Costco Deli Fresh Yakisoba Stir Fry Kit: A Complete Meal
The fresh **Costco yakisoba stir fry** kit from the deli section is a game-changer for busy households. It comes pre-portioned with all the components needed for a full meal, making dinner prep incredibly straightforward.
Cooking Instructions for the Deli Kit
While the specific instructions are printed on the packaging, here’s a detailed guide on **how to cook Costco yakisoba stir fry** to perfection, ensuring a restaurant-quality meal right in your kitchen:

1. Prepare Your Pan: Heat a wok or a large sauté pan over medium-high heat on your stovetop. Add approximately ¼ cup of cooking oil (the kit typically suggests 2 ounces, which is roughly ¼ cup). Ensuring your pan is adequately heated before adding ingredients is key to achieving that signature stir-fry texture.
2. SautĂ© the Vegetables: Carefully add the mixed vegetables from the kit to the hot pan. Cook for about 2 minutes, stirring frequently. Don’t be surprised by the generous amount of vegetables; they are often hidden beneath the noodles in the packaging, providing a substantial and healthy component to the dish. Stir-frying at a high temperature ensures they remain tender-crisp, not soggy.
3. Add the Chicken: Introduce the seasoned chicken to the pan with the vegetables. Continue to cook for another 2 minutes, stirring occasionally. The goal is to heat the chicken thoroughly and allow it to develop a nice sear.
4. Combine Noodles and Sauce: Finally, add the yakisoba noodles and the savory sauce to the pan. Cook for just 1 minute, stirring continuously to ensure all ingredients are evenly coated with the rich sauce. The **Costco yakisoba noodles stir fry** is ready once it reaches a safe internal temperature of 165°F (74°C). Always use a meat thermometer to verify, especially with chicken.

Taste and Texture Review of Costco Deli Yakisoba
Our experience with the Costco deli yakisoba was overwhelmingly positive. We were particularly impressed by the generous quantity of vegetables, which were surprisingly abundant once stirred out from beneath the noodles in the container. The balance of vegetables to noodles felt satisfying and well-proportioned. The sauce itself was a highlight – a harmonious blend of salty and subtly sweet notes that truly enhanced the entire dish. It’s a flavor profile that appeals to a wide range of palates, making it a crowd-pleaser for family meals or entertaining.

For those who are sensitive to salt or prefer a milder flavor, a great tip is to use only half of the provided sauce initially. After a quick taste test, you can always add more to achieve your desired seasoning level. This allows for personalized customization, ensuring everyone can enjoy the dish to their preference.

Storage and Reheating Tips
Any leftover **Costco yakisoba stir fry** should be stored promptly in a covered, airtight container in the refrigerator. It will keep well for up to 3-4 days. To reheat individual portions, simply place them in a microwave-safe bowl and heat on high for 1-2 minutes, or until thoroughly warmed through. Alternatively, you can reheat it in a pan on the stovetop over medium heat, stirring occasionally, until hot.
Optimal Heat for Stir Frying
A common question when preparing stir-fries is about the ideal cooking temperature. Generally, stir-fries benefit from being cooked quickly over medium-high to high heat in a wok or large pan. This high heat is crucial for searing the meat, locking in its juices, and ensuring the vegetables retain their desirable tender-crisp texture, preventing them from becoming soft and overcooked.
Costco Frozen Vegetable Yakisoba: A Versatile Side
Beyond the fresh deli option, Costco also offers a convenient frozen vegetable yakisoba, often under the Ajinomoto brand. This product serves as an excellent side dish or a quick, light meal, particularly appealing to vegetarians or those seeking a meatless option. It’s perfect for when you need a fast and flavorful addition to your dinner spread.
Microwave Cooking Instructions for Frozen Yakisoba
For the ultimate in speed and simplicity, the frozen **Costco veggie yakisoba** can be prepared in the microwave:

1. Vent the Bag: Tear open a small corner of the yakisoba bag to create a vent for steam to escape during cooking.
2. Microwave: Place the bag in the microwave and cook on high for approximately 3 minutes. (Note: These directions are based on an 1100-watt microwave; cooking times may vary based on your microwave’s power.)
3. Serve Carefully: Exercise caution when handling the bag as it will be extremely hot and filled with steam. Carefully tear the bag open, pour the contents into a bowl, and enjoy your quick veggie yakisoba.
Stovetop Cooking Instructions for Frozen Yakisoba
For a slightly more involved but often preferred method that can enhance texture, here’s how to cook Costco frozen veggie yakisoba on the stove:
1. Boil Water: Bring 1 cup of water to a boil in a shallow, non-stick pan on your stovetop.
2. Add Yakisoba: Empty one bag of frozen yakisoba into the boiling water, ensuring the vegetable side is facing down.
3. Cook and Stir-fry: Heat on high for 6 minutes, then flip the noodles over. Continue to lightly stir-fry for another 3-4 minutes, or until all the water has evaporated and the noodles are heated through and slightly caramelized. Serve immediately and enjoy.
Costco Yakisoba Serving Sizes
The prepared **Costco yakisoba stir fry** from the deli is designed to serve 4-6 individuals as a complete, one-pan meal. This makes it an ideal option for families or small gatherings. In contrast, a box of Costco’s frozen yakisoba typically contains 6 individually packaged servings, making it perfect for single portions or as a flexible side dish.

The fresh option provides significantly more protein per calorie, making it a more robust main dish choice.

FAQs About Costco Yakisoba
Can you freeze Costco yakisoba stir fry?
While technically possible, freezing the fresh Costco Yakisoba Stir Fry is not recommended if you prioritize texture and quality. Freezing can cause the vegetables to become mushy and the noodles to turn soggy. Additionally, the sauce may separate upon thawing, potentially diminishing the overall flavor of the dish. It’s best enjoyed fresh or from its original frozen state.
Are yakisoba noodles from Costco vegan?
The noodles themselves in the Kirkland yakisoba stir fry are typically vegan. However, the fresh deli kit includes chicken, making it unsuitable for a vegan diet. The frozen Ajinomoto vegetable yakisoba, on the other hand, appears to be a vegan-friendly product, as its ingredient list does not contain animal-derived components.
What is the sauce for Costco yakisoba?
The sauce for Costco yakisoba shares many similarities with teriyaki sauce and can often be used interchangeably in a pinch. Traditional teriyaki sauce is typically made from soy sauce, sugar, sake or mirin (rice wine), and sometimes includes ginger and garlic. Costco’s yakisoba sauce incorporates these base flavors but also adds ketchup, which contributes a unique tang and richness to its overall profile.
Are yakisoba noodles already cooked?
Yes, most yakisoba noodles, including those found in both the fresh and frozen Costco kits, are pre-cooked. This is why they only require a brief reheating period during stir-frying. If you’re using dried yakisoba noodles purchased separately, they would typically need to be boiled in water for a few minutes until tender yet still slightly firm before being added to a stir-fry.

Notes
đź’ Expert Tips from Dietitian Summer Yule
This is a level 2 recipe (transition or weight maintenance). Can yakisoba be healthy? Yakisoba can be a healthy dish if prepared with the right ingredients and in moderation. Get more information on making healthy yakisoba in my beef yakisoba recipe.
My main complaint about all of the prepared yakisoba options is that they are very high in sodium. If you eat a double portion of the yakisoba stir fry from the Costco deli, you’re getting 2020 mg sodium. That’s close to the recommended sodium limit for an entire day.
On the other hand, we really enjoyed the Costco yakisoba for a quick, tasty, and balanced meal. (Balanced in the sense that it provided a range of food groups, including lots of vegetables.) I would definitely purchase this one again, and you can always use half the sauce if you want things less salty.
Nutrition information is for one serving of the Costco yakisoba stir fry kit (6.75 ounces). A more realistic portion is likely a double serving, in which case the nutrition info below should be doubled.
