Our keto Cincinnati chili recipe ingeniously swaps refined grain spaghetti for nutrient-rich roasted spaghetti squash, transforming a classic comfort food into a low-carb, low-calorie chili that’s both delicious and diet-compliant. If you’re unfamiliar with the iconic Cincinnati 5-way chili, also famously known as Skyline Chili, prepare to discover a culinary experience unlike any other, now reimagined for healthy eating.

The Iconic Taste of Cincinnati Chili: A Culinary Journey
The distinctive recipe for Cincinnati chili emerged in the 1920s, a culinary innovation credited to immigrant restaurateurs in Cincinnati, Ohio. Brothers Tom and John Kiradjieff are widely recognized for inventing this beloved dish, which has since become an enduring symbol of the Cincinnati region’s rich food culture. Far from a typical chili, this unique creation boasts a fascinating history and a flavor profile that sets it apart.
You don’t need to live in Ohio to enjoy this regional favorite. This guide will show you how to prepare a healthy and incredibly flavorful version of this chili right in your own kitchen. But first, let’s delve deeper into what exactly makes Cincinnati chili so special and why it has captured the hearts (and taste buds) of so many.
What Makes Cincinnati Chili Different?
What is the difference between chili and Cincinnati chili? Unlike the thick, robust, and often spicy chili found in other parts of the United States, Cincinnati chili presents a notably different character. It is often referred to as Skyline chili, a nod to a prominent chain of chili restaurants in the greater Cincinnati area that has popularized the dish. The classic Cincinnati chili recipe features a meaty, subtly spiced chili, unique for its use of unexpected ingredients like cinnamon, allspice, and sometimes even a touch of cocoa powder, giving it a Mediterranean-inspired aroma. Crucially, it is traditionally served over a bed of spaghetti.
A basic serving of chili over spaghetti is known as a “2-way.” However, the true Cincinnati experience involves customizing your dish with a variety of toppings, giving rise to the famous “ways” system. Whether you’re a purist or prefer a more loaded plate, Cincinnati chili offers a truly personalized dining adventure.
Understanding the “Ways” of Cincinnati Chili
The “ways” system is an integral part of the Cincinnati chili experience, allowing diners to customize their meal precisely to their preferences. Each “way” adds another layer of flavor and texture, building up to the legendary 5-way. Here’s a breakdown of how you can order and enjoy your chili:
- 2-Way: This is the simplest form, featuring chili served generously over a mound of spaghetti.
- 3-Way: Building on the 2-way, this adds a generous blanket of shredded cheddar cheese on top of the chili and spaghetti. This is arguably the most popular way to enjoy Cincinnati chili.
- 4-Way: For those who desire more, the 4-way introduces an additional topping. You can choose either chopped onions OR chili beans (typically kidney beans) to go on top of your chili, spaghetti, and cheese.
- Cincinnati Chili 5-Way: The ultimate indulgence, the 5-way combines all the elements: chopped onions AND chili beans are added to the chili, spaghetti, and cheese, creating a hearty and flavorful dish that truly satisfies.
Beyond the core “ways,” many establishments and home cooks also offer oyster crackers and hot sauce as optional additions, allowing for even further customization of this iconic dish.
Transforming Cincinnati Chili into a Keto-Friendly Masterpiece
In our modern take on this Cincinnati-style chili recipe, we’re making it compatible with a low-carb, ketogenic diet without sacrificing any of its signature appeal. The most significant adaptation involves substituting traditional wheat-based spaghetti with roasted spaghetti squash. This clever swap not only drastically reduces the carbohydrate count but also introduces a subtle, sweet earthiness and a delightful texture that mimics conventional pasta.
To fully embrace the “ways” while maintaining keto compliance, we include classic toppings like shredded cheddar cheese and chopped onions. For the beans, which are typically high in carbs, we opt for low-carb black soy beans, offering a similar texture and protein boost without the carb overload. The result is a truly satisfying low-calorie Cincinnati chili spaghetti that is both keto-friendly and naturally gluten-free. Incorporating this modified Cincinnati chili recipe into your healthy eating plan can be a delicious strategy to support your weight loss and dietary goals, proving that comfort food can indeed be healthy and delicious.
Key Ingredients for Your Keto Cincinnati Chili
To create the ultimate keto Cincinnati chili copycat recipe, you’ll need a carefully selected blend of savory ingredients and aromatic spices that capture the essence of the original. Here’s a comprehensive list of what goes into the flavorful chili base:
- Extra lean ground beef: The foundation of the chili, providing a rich, meaty flavor.
- Water: To help simmer the chili to the perfect consistency.
- Canned tomato sauce: Adds a tangy depth and classic chili base.
- Chili powder: A foundational spice for any chili, offering warmth and flavor.
- Cumin: Earthy and aromatic, essential for the chili’s spice profile.
- Cinnamon: One of the signature “secret” ingredients in Cincinnati chili, adding a distinct, warm, and slightly sweet note.
- Ground cloves: Another unique spice that contributes to the chili’s complex and aromatic character.
- Salt: Enhances all the flavors.
- Crushed red pepper: For a subtle hint of heat, adjustable to your preference.
- Garlic powder: A savory staple that complements the meat and tomato.
- Bay leaf: Infuses a subtle, herbaceous aroma during simmering.
- Apple cider vinegar: A touch of acidity to brighten the flavors and balance the richness.

(You’ll find specific quantities for these ingredients in the detailed recipe card at the end of this post.)
To truly experience the 5-way Skyline chili in its keto-friendly glory, you’ll also need these essential components for building your customized dish:
- Roasted spaghetti squash: Your low-carb foundation, replacing traditional spaghetti.
- Shredded cheese: A generous topping of sharp cheddar cheese is classic.
- Black soy beans: A fantastic low-carb alternative to conventional chili beans.
- Chopped white onion: Adds a fresh, pungent crunch.
The transformation begins with the choice of “noodles.” Our recipe proudly features roasted spaghetti squash, a fibrous vegetable that, when cooked, shreds into pasta-like strands. This is a crucial element for making our Cincinnati chili lower in carbohydrates and calories. For one of the easiest and most flavorful ways to prepare this versatile veggie, try our Air Fryer Spaghetti Squash method.
Mastering Spaghetti Squash: Your Low-Carb Noodle Alternative
Preparing spaghetti squash doesn’t have to be a daunting task. While roasting in the oven offers a lovely caramelized flavor, there are several convenient methods to get perfectly tender strands:
Microwave Method: For a quick and effortless approach, pierce the spaghetti squash all over with a sharp knife. Microwave it on high for about 6-8 minutes, or until softened. Once cooked, the squash strands are incredibly easy to separate with a fork. Keep in mind that microwave heating times can vary based on your appliance’s wattage and the size of the squash, so you might need to adjust the cooking duration slightly.
Oven Roasting Method: If you’re simmering your chili for an hour, roasting the spaghetti squash in the oven simultaneously is an excellent option that doesn’t add extra time to your overall meal preparation. Simply halve the squash, scoop out the seeds, brush with a little oil, and roast until tender. This method often yields slightly firmer, more flavorful “noodles.”
Instead of the traditional kidney beans often found in a 5-way chili, we utilize black soy beans. These canned beans are remarkably low in net carbs and provide a complete protein, making them ideal for a keto diet. We’ll discuss other low-carb bean substitutes further down for more flexibility. To bring this delicious Skyline chili to life, you’ll primarily need a sturdy cast iron skillet and a metal spatula for the chili, plus a good knife for preparing your fresh toppings.
Step-by-Step: Crafting Your Keto Cincinnati Chili at Home
Making a keto-friendly Skyline chili is straightforward. Follow these simple steps to create a hearty and flavorful dish:

Begin by browning the extra lean ground beef in a large cast iron skillet over medium heat. As it cooks, use a metal spatula to break the beef into fine crumbles. This ensures the chili has the characteristic texture of Cincinnati-style meat sauce.
Once the beef is browned, drain any excess fat. Then, add the water, canned tomato sauce, chili powder, cumin, cinnamon, ground cloves, salt, crushed red pepper, garlic powder, bay leaf, and apple cider vinegar to the skillet. Stir everything well to combine. Bring the mixture to a gentle simmer, then reduce the heat to medium-low and let it cook for 30 minutes, or up to 1 hour, stirring occasionally. This simmering time allows the flavors to meld beautifully and the unique spices to infuse the meat.
During the simmering process, the liquid in the chili should mostly evaporate, leaving you with a rich, thick meat sauce. If you notice it drying out too quickly or becoming too thick for your preference, you can partially cover the pan to retain more moisture or add a splash of beef broth.
Once the chili has finished simmering and reached your desired consistency, remove the bay leaf. To serve, ladle the flavorful chili over a generous portion of roasted spaghetti squash. Then, customize your dish with your chosen “ways” by adding chopped onions, low-carb black soy beans, and a sprinkle of shredded cheddar cheese on top, as desired.
Cooking Tip! It’s helpful to approach Skyline chili as more of a meat sauce than a traditional chunky chili. Authentic Cincinnati chili often has a thinner consistency, but for easier eating, many prefer it thicker. If you desire a thinner consistency, simply stir in some beef broth until it reaches your liking. This flexibility allows you to tailor the dish perfectly to your preference.

Storage and Reheating: Enjoying Your Chili Longer
To maximize the freshness and flavor of your homemade low-carb Cincinnati chili, proper storage is key. Transfer any leftover chili to an airtight container and store it in the refrigerator for up to 3-4 days. It’s best to keep the roasted spaghetti squash separate from the chili until you’re ready to serve, as this helps maintain its texture and prevents it from becoming overly soggy.
When you’re ready for another meal, this keto Skyline chili reheats beautifully. You can gently warm it on the stovetop over medium-low heat, stirring occasionally, or use the microwave for a quicker option. For stovetop reheating, you might add a splash of water or beef broth if the chili has thickened too much in the fridge.
This keto Skyline chili can also be frozen for longer storage. Allow the chili to cool completely before transferring it to a freezer-safe, airtight container. It can be stored in the freezer for up to 3 months. However, be aware that spaghetti squash tends to become a bit watery and softer in texture after freezing and thawing. For the best experience, it’s recommended to prepare fresh spaghetti squash each time you serve the frozen chili. Alternatively, you can use a bag of pre-frozen veggie noodles, such as zucchini noodles, which hold up well after freezing, to pair with your reheated chili.
Exploring Keto Alternatives and Customizations
One of the great advantages of making your own Skyline Chili low-carb version is the flexibility to customize it to your dietary needs and preferences. There are numerous ways to modify this recipe, whether you’re looking for shortcuts or different low-carb ingredient options.
Canned Chili Shortcut: For an incredibly quick meal, you can use low-carb canned chili in place of making the chili from scratch. Many brands offer varieties that fit a ketogenic diet. You can buy canned Skyline chili here (on Amazon), which boasts only 2 grams of net carbs per serving, making it an excellent base for a speedy keto meal.
Keto-Friendly Beans: Traditional Cincinnati chili often includes kidney beans in its 4-way and 5-way variations. If you want to include beans in your keto Skyline chili, several low-carb options exist. Besides the black soy beans we recommend, you could also try lupini beans or shelled edamame. These alternatives offer fiber and protein without significantly impacting your carb count. For those following a Paleo diet, simply skip the cheese and beans altogether.
Low-Carb Pasta Substitutes: While roasted spaghetti squash is our primary recommendation for a low-carb noodle base, you have other excellent options if you prefer variety or different textures. Here are a few popular spaghetti substitutes suitable for Cincinnati chili:
- Palmini noodles: Made from hearts of palm, these noodles are very low in carbs and have a neutral flavor.
- Shirataki noodles: Also known as konjac noodles, they are virtually carb-free and excellent for absorbing the chili’s flavors.
- Zucchini noodles (zoodles): Freshly spiralized zucchini offers a light, refreshing, and ultra-low-carb base.
Keto Cracker Alternatives: If you enjoy the traditional crunch of oyster crackers with your chili, you can easily find keto-friendly substitutes. Consider using pork rinds, keto cheese crisps, or your favorite keto crackers to add that satisfying texture without the carbs.

Frequently Asked Questions About Cincinnati Chili
Skyline Chili vs. Gold Star Chili – What’s the Difference?
Gold Star Chili is another prominent restaurant chain in the Cincinnati, OH area that serves its own version of Cincinnati chili, complete with the famous “ways.” While both are beloved, subtle differences exist. Some aficionados claim Gold Star chili is slightly meatier, while others find it a touch thicker or spiced differently. The debate often boils down to personal preference, making it a fun culinary challenge to conduct your own taste test if you ever find yourself in the region!
What’s the Skyline Chili Menu?
The Skyline Chili restaurant menu typically features their signature chili in all its “ways” (2-way, 3-way, 4-way, 5-way), often served over spaghetti, hot dogs (Coneys), or in bowls. You’ll also find sides like fries and salads. Their full menu can be found on their official website, detailing offerings at their locations across Ohio, Indiana, Kentucky, and Florida.
What’s Skyline Coney Bowl?
The Skyline Coney Bowl is a popular menu item at Skyline Chili restaurants, especially for those who love their hot dogs. It typically consists of three hot dogs, cut into pieces, served in a bowl filled with Skyline chili and generously topped with shredded cheddar cheese. It’s a hearty and comforting meal that combines two of Cincinnati’s favorite chili-based offerings.
How to Make Cincinnati Chili Vegetarian?
To make a vegetarian Cincinnati chili, you have several excellent options. Instead of ground beef, you can use plant-based ground meat alternatives like Beyond Beef, which mimics the texture and richness of red meat very well. A whole-foods approach would involve using cooked lentils as the base, offering a fibrous and protein-rich alternative. For a truly vegan Cincinnati chili, you would need to replace both the meat substitute and the dairy cheese with your favorite vegan alternatives, such as plant-based ground and dairy-free shredded cheese.
How to Make Instant Pot Cincinnati Chili?
You can certainly adapt this keto Cincinnati chili recipe for an Instant Pot or Ninja Foodi. Start by browning the ground beef using the “Sauté” function. Once browned, add all the remaining chili ingredients. Cook on high pressure for about 10-15 minutes, followed by a natural release. Alternatively, for a “set it and forget it” approach, you can make slow cooker Cincinnati chili. Brown the beef in a skillet first, then transfer it and all other ingredients to a Crock-Pot. Cook on low for 6-8 hours, adding additional water or broth if a thinner consistency is desired.
What is the Secret Ingredient in Skyline Chili?
The “secret ingredient” in authentic Skyline Chili is a topic of much debate among fans and food historians. While the exact blend remains a closely guarded trade secret, commonly cited “secret” ingredients include cinnamon, unsweetened cocoa powder, and bay leaf. Each of these spices contributes to the chili’s distinct, almost Mediterranean flavor profile. Our copycat recipe incorporates cinnamon and bay leaf, which are essential for that characteristic taste. While some recipes suggest cocoa powder, we find it’s not strictly necessary for achieving a delicious and authentic-tasting keto version.

Notes
Expert Tips from Dietitian Summer Yule
This is a level 1 recipe (may help support fat loss). Is Skyline chili bad for you? The original Skyline chili is high in calories, sodium, and refined carbs. I would consider this keto Skyline chili to be a healthier option, depending on what you’re looking for.
Skyline restaurant chili has 2040mg sodium in a regular 3-way chili, and 2310mg sodium in a regular 5-way chili. The recommended daily limit for sodium (per the Dietary Guidelines) is 2300mg per day. Our low-carb chili recipe is a much better choice if you’re watching your sodium intake.
It may come as a surprise, but this cheesy, beefy plate of deliciousness clocks in at around 500 calories. Swapping out refined grain noodles for spaghetti squash is an easy way to lower the calories and carbs in this dish. Try spaghetti squash in other pasta recipes to create new, better-for-you family favorites.
Another benefit of using spaghetti squash is that it offers fluid volume and fiber. These elements can help volume eaters feel full on fewer calories.
Like the original Skyline chili recipe, our keto version offers plenty of protein to help keep you full. Adding the black soy beans and cheese toppings will help boost the protein up even more.
