For many, preparing authentic Greek spanakopita from scratch can be a time-consuming and intricate process, involving delicate phyllo dough handling and a rich, flavorful filling. This is precisely where frozen spanakopita from Costco shines, offering unparalleled convenience without compromising on taste or quality. Opting for ready-to-bake frozen spanakopita saves you valuable time and effort, making it an ideal choice for busy weeknights, impromptu gatherings, or simply when you crave a delicious, hassle-free snack. With our optimized air fryer spanakopita recipe, you can transform these frozen delights into crispy, golden perfection in approximately 10-12 minutes, delivering a taste of the Mediterranean right to your table with minimal fuss.
While the original Costco spanakopita cooking instructions are provided on the packaging, it’s not uncommon for boxes to get misplaced. Fear not! We’ve meticulously tested and refined the best practices for preparing these savory treats. Here, you’ll find reliable frozen spanakopita cooking instructions for both air fryers and traditional ovens. We’ve even made a few minor tweaks to the standard Costco spanakopita air fryer directions to guarantee they turn out perfectly puffed, gloriously golden, and irresistibly crispy.
Each box of these delightful Costco spinach and feta mini pies contains a generous 48 pieces, making it an excellent value and an ideal quantity for larger social events, such as holiday parties, family potlucks, or game day festivities. The substantial quantity ensures you’ll have plenty to share, or to keep stocked for multiple occasions.
Costco understands that you might not always need to prepare all 48 spinach triangles at once. To preserve freshness and convenience, the spanakopita are thoughtfully packaged into four individual trays, with 12 triangles in each. This intelligent portioning allows you to cook smaller batches as needed, ensuring that the remaining frozen pastries stay fresh and are ready for future enjoyment. This flexibility makes them perfect for smaller households or for serving as a quick snack for one or two people.

Despite the generous quantity and thoughtful packaging, these delicious appetizers have a tendency to disappear remarkably fast once they’re out of the freezer. Their irresistible flavor and perfectly crispy texture make them a crowd-pleaser that rarely lingers for long!
🔪 How to Cook Spanakopita from Costco
Curious about how to cook frozen spanakopita for the best results? You have two primary options: your oven or an air fryer. For optimal crispiness and browning of the phyllo dough, it’s crucial to avoid using a microwave. Microwaving will unfortunately result in soggy, unappealing pastries that lack the signature flaky texture spanakopita is known for. Stick to conventional heating methods for a truly satisfying experience.
❓ How to Cook Costco Spanakopita in an Air Fryer for Perfect Crispiness
The air fryer has revolutionized how we prepare frozen foods, and Costco spanakopita is no exception. This method offers a quick and efficient way to achieve beautifully golden and crispy pastries. You can use any brand of air fryer, whether it’s a Ninja Foodi, Philips, Instant Pot Vortex, Cosori, Nuwave, Kalorik, or Breville. Remember that cooking times can vary slightly between different air fryer models and wattages, even more so than between ovens. To prevent overcooking and ensure perfect results, always check your food a little earlier than recommended the first time you try a new air fryer recipe.
To begin this simple frozen spanakopita air fryer recipe, start by preheating your air fryer to 350 degrees Fahrenheit (177°C) for a full 5 minutes. Proper preheating is essential for achieving that desirable crispy phyllo dough. Once preheated, carefully arrange the frozen spanakopita pieces in a single layer within the air fryer basket or on the tray. It’s crucial that the pastries do not touch each other, as this allows hot air to circulate evenly around each piece, promoting uniform cooking and crisping. Depending on the size of your air fryer, you should be able to fit approximately 8-9 spinach triangles per batch.

Ensure that the spanakopita triangles are placed glazed side up. This helps in achieving that beautiful golden-brown finish. Carefully slide the tray or basket back into the air fryer. If you have an air fryer oven model, use the top rack position for best results. Air fry for 10-11 minutes. There’s no need to flip them halfway through, making this method even more convenient.
While the Costco spanakopita box directions suggest an air frying time of 10-13 minutes, our tests revealed that 13 minutes was often too long for most air fryer models. At the 10-minute mark, the pastries typically achieve a lovely golden brown color and a crispy texture. By 11 minutes, you’ll notice the spanakopita puffing up beautifully, with some pieces just beginning to show slight splitting in the phyllo layers, indicating they are perfectly done. Continuing to cook them beyond this point could lead to over-browning or a messy, crumbly texture, so keep a close eye on them during the last few minutes.
The box recommends cooking frozen spanakopita until it reaches a safe minimum internal temperature of 165°F (74°C). To verify this, use an instant-read thermometer to check the internal temperature of a pastry after air frying. Insert the thermometer into the thickest part of the filling. If the temperature hasn’t been reached, add additional cooking time in 1-2 minute increments until it’s safe to eat.
Once cooked, allow your air fryer spanakopita to rest for about 2 minutes. The filling and outer layers will be extremely hot right out of the air fryer, and a brief resting period helps the internal temperature stabilize and prevents you from burning your mouth. This short wait also allows the phyllo to set, maintaining its crispiness.

⏲ Costco Spanakopita Oven Baking Instructions
If you prefer a more traditional cooking method or are preparing a larger batch, the conventional oven is an excellent choice for baking Costco spanakopita. This method provides consistent heat, ensuring a uniformly golden and crispy result across all your pastries. Follow these straightforward steps to bake your frozen spanakopita to perfection.
To bake frozen spanakopita in the oven, start by preheating your oven to 400°F (200°C). While the oven heats up, arrange the frozen spanakopita pieces on a non-stick cookie sheet or a baking tray lined with parchment paper. Place them glazed side up, ensuring they are not touching each other to allow for proper air circulation and even browning. It’s important not to break the individual triangles apart if they are slightly stuck together from freezing; they will separate naturally as they bake.
Bake the Costco spanakopita for 17-19 minutes, placing the cookie sheet in the center of the oven for even heat distribution. You’ll know they are done when they’ve turned a beautiful golden brown and have puffed up, indicating the phyllo layers are perfectly flaky and the filling is hot. As with air frying, always check the internal temperature with a meat thermometer to ensure it reaches a safe 165°F (74°C). This ensures food safety while guaranteeing the filling is thoroughly heated through. A final rest of 2 minutes before serving is recommended to allow the pastries to cool slightly and firm up.

🤔 Why You Should NOT Microwave Costco Spanakopita
The packaging for Costco spanakopita explicitly states, “Do not prepare in the microwave oven.” This warning is crucial and should be heeded. The delicate phyllo dough, which is central to spanakopita’s appeal, simply does not brown or crisp up properly in a microwave. Instead of developing a beautiful golden, flaky exterior, microwaved spanakopita will turn out soggy, limp, and unappetizing. To truly enjoy the authentic texture and flavor of these Greek pastries, always opt for baking in a conventional oven or air fryer.

🌡️ Can Spanakopita Be Frozen After Cooking?
For optimal texture and flavor, Costco spanakopita should be kept frozen until you are ready to cook it. It’s generally recommended to only prepare the amount you intend to consume immediately. While it is technically possible to freeze leftover cooked spanakopita, the quality can significantly diminish upon thawing and reheating. The delicate phyllo dough, once baked and then frozen, tends to lose its crispiness and can become quite soggy. For the best experience, enjoy your spanakopita fresh out of the oven or air fryer.
👪 Delightful Spanakopita Dips and Serving Suggestions
So, what exactly pairs well with spanakopita? Traditionally, spanakopita is served alongside tzatziki dip, a refreshing Greek yogurt-based sauce with cucumber, garlic, and dill. Its cool and creamy texture perfectly complements the savory, flaky pastry. Other excellent options include a simple cucumber yogurt dressing, a zesty lemon-dill sauce, or even a spicy feta dip for those who enjoy a kick. You can also enhance the spanakopita itself by sprinkling it with additional seasonings like za’atar or fresh oregano after baking, adding an extra layer of authentic Mediterranean flavor.

For a more substantial meal, consider serving spanakopita with a fresh Greek salad, a light tomato and cucumber salad, or even a simple lentil soup. It also makes a fantastic appetizer for larger meals, adding an authentic touch to any Mediterranean spread.
Frequently Asked Questions (FAQs) About Costco Spanakopita
How much does Spanakopita cost at Costco?
At the time of writing, the average price for Costco spanakopita (a box of 48 pieces) is approximately $14.99. However, it’s important to remember that prices can fluctuate based on your specific Costco location, regional promotions, and are always subject to change. It’s always a good idea to check your local store for the most current pricing.
What’s the best frozen spanakopita brand?
Determining the “best” frozen spanakopita is largely a matter of personal preference. Different brands offer slight variations in filling flavor, phyllo crispiness, and overall seasoning. To find your favorite, we recommend conducting a taste test! Beyond the popular Cuisine Adventures brand available at Costco, you might also explore options such as Apollo Spinach & Cheese Spanakopita, Grecian Delight Cheese and Spinach Pie, and The Fillo Factory Spinach & Cheese Fillo Pie. Each offers a unique take on this classic Greek pastry.
Is phyllo pastry healthier than puff pastry?
The term “healthier” is subjective and depends on individual dietary needs and goals. However, when comparing phyllo dough to puff pastry, phyllo typically emerges as the lower-fat and lower-calorie option before preparation. Phyllo consists of paper-thin sheets of dough that are inherently low in fat. Puff pastry, on the other hand, is made with a significant amount of butter or other fats layered within the dough to create its characteristic flaky texture. While phyllo dough itself is lighter, many recipes call for brushing oil or butter between its numerous layers during preparation, which can increase the overall fat and calorie content of the final dish. Even with added fat, spanakopita made with phyllo dough often has fewer calories and less saturated fat than a comparable dish made with puff pastry, making it a slightly lighter choice for those mindful of their intake.

Notes
💭 Expert Tips from Dietitian Summer Yule
This is a level 3 recipe (suitable for weight maintenance and active lifestyles). How healthy is spanakopita?
The first and most prominent ingredient in Cuisine Adventures Costco spanakopita is spinach, providing some valuable nutrients. Additionally, you benefit from calcium and a decent amount of protein from the feta cheese, along with an assortment of B vitamins from the enriched flour in the dough.
That being said, Costco’s spanakopita, like many convenient frozen foods, falls into the category of ultra-processed foods. Foods in this category often contain a higher proportion of refined grains and added fats relative to protein and fiber. Many individuals find highly palatable foods like these very easy to overeat (and I certainly can relate!).
If you were to prepare spanakopita entirely at home, you would have the freedom to control ingredients, potentially using less oil and opting for whole grains in your phyllo dough. You could also increase the ratio of nutrient-dense filling to dough. However, realistically, making spanakopita from scratch is a labor-intensive endeavor that requires a certain degree of culinary skill and time.
For these reasons, I personally enjoy Costco spanakopita as an occasional treat. It’s incredibly convenient to have a box in the freezer for unexpected guests, or when my college-aged son visits home. However, it wouldn’t be my primary dietary staple if I were actively pursuing a weight loss goal or focused on rigorous weight maintenance.
To enhance the nutritional profile and flavor of this appetizer, consider serving it with a creamy, protein-rich yogurt-based dip, such as tzatziki. Not only does this add a boost of protein, but it also provides a refreshing and delicious counterpoint to the crispy spinach triangles.
Nutrition information provided is for one serving of plain Costco spanakopita (3 pieces) and does not include any added dips.
