Ingredients in Costco’s Frozen Lasagna

Frozen Lasagna Cooking Methods
There are several effective methods for cooking frozen lasagna from Costco, each yielding different results in terms of texture and flavor. The primary methods are:
- Oven Baking
- Microwave
- Convection Oven
Each method will be discussed in detail below.
1. Oven Baking
Oven baking is the most recommended method for cooking frozen lasagna. This technique ensures even cooking and allows the cheese to melt beautifully while the edges become wonderfully crispy.
Cooking Instructions for Oven Baking
To prepare your lasagna using the oven, follow these steps:
- Preheat the Oven: Preheat your oven to 375°F (190°C). This step is crucial for even cooking.
- Remove Packaging: Take the frozen lasagna out of its packaging. If it’s in a plastic tray, it’s essential to transfer it to an oven-safe dish to avoid melting the plastic.
- Cover with Foil: Cover the lasagna with aluminum foil. This keeps moisture in and prevents the cheese from burning during the initial stages of cooking.
- Bake: Place the covered lasagna in the preheated oven and bake for about 50 minutes.
- Uncover and Continue Baking: After 50 minutes, carefully remove the foil and continue baking for another 15-20 minutes. This allows the cheese to caramelize and gives a nice golden color.
- Check for Doneness: The lasagna is done when it reaches an internal temperature of 165°F (74°C). You can use a meat thermometer to check.
- Rest Before Serving: Once cooked, let the lasagna rest for 10-15 minutes. This helps set the layers, making it easier to cut and serve.
Following this method will result in a deliciously baked lasagna, ready to impress your family or guests.
2. Microwave Cooking
If you’re short on time, the microwave method is a viable option, though it may not achieve the same crispy texture as oven baking.
Cooking Instructions for Microwave
To microwave your Costco frozen lasagna, use these straightforward steps:
- Remove Packaging: Just like the oven method, start by removing any plastic packaging. If it’s in a microwavable dish, leave it there.
- Cover: Cover the lasagna loosely with microwave-safe plastic wrap to avoid splatters.
- Microwave Settings: Set your microwave to medium power and cook the lasagna for about 7-10 minutes. This can vary depending on the wattage of your microwave – start checking at 7 minutes.
- Check Temperature: Use a food thermometer to ensure the internal temperature reaches at least 165°F (74°C) before removing.
- Let it Rest: Allow the lasagna to sit for 2-3 minutes before serving. This will help distribute the heat evenly throughout the dish.
Although quicker, using the microwave may result in a softer texture for the noodles and cheese. Therefore, it’s suggested to reserve this method for days when you need something fast and easy.
3. Convection Oven Method
For those who own a convection oven, this method offers the advantage of quicker cooking times and can achieve a delightful crispiness.
Cooking Instructions for Convection Oven
To cook your frozen lasagna using a convection oven, follow these steps:
- Preheat the Convection Oven: Set it to 350°F (175°C). The lower temperature compared to a regular oven helps prevent over-browning.
- Prepare the Lasagna: As with the other methods, remove the packaging and transfer the lasagna to an oven-safe dish if needed.
- Cover with Foil: Initially cover it with aluminum foil to trap moisture, but remove it halfway through.
- Bake: Cook the lasagna for about 30-45 minutes, monitoring closely. The convection oven circulates air, allowing for faster cooking compared to a standard oven.
- Check for Doneness: Confirm the internal temperature reaches 165°F (74°C), and the cheese is bubbly and lightly browned.
- Cool Before Serving: Allow the lasagna to rest for about 10 minutes.
This method produces delicious results and can be especially useful when cooking for large gatherings.
Serving Suggestions for Your Frozen Lasagna
Once your lasagna is cooked to perfection, it’s time to think about how to present and enjoy this delightful dish.
Accompaniments
Pair your lasagna with the following sides for a complete meal:
- Garlic Bread: Nothing beats the classic combination of lasagna and garlic bread. It’s easy to make, and it’s a wonderful way to scoop up extra sauce.
- Mixed Green Salad: A fresh green salad drizzled with vinaigrette balances the rich flavors of lasagna nicely.
You can get creative with different salads, dressings, or even roasted vegetables to complement your meal.
Storing Leftovers
If you’re fortunate enough to have leftovers, storing them correctly can extend their shelf life:
- Cool Completely: Allow any leftover lasagna to cool to room temperature.
- Airtight Container: Transfer portions into airtight containers.
- Refrigeration: Store in the refrigerator for up to 3-5 days, or freeze for up to 3 months for longer storage.
When you’re ready to eat the leftovers, you can reheat them in the oven or microwave, following similar cooking instructions, ensuring it reaches an internal temperature of 165°F (74°C) before serving.

What are the recommended cooking times for Costco’s frozen lasagna?
The recommended cooking time for Costco’s frozen lasagna can vary depending on the oven temperature. Generally, you should bake it at 375°F for about 70 to 80 minutes when frozen. It’s important to check the lasagna’s internal temperature with a food thermometer; it should reach at least 165°F to ensure it is fully heated and safe to eat.
If you prefer to cook the lasagna from thawed, reduce the baking time to approximately 50 to 60 minutes, again checking that the internal temperature meets the recommended safety standards. Always cover the lasagna with aluminum foil for the first part of the cooking process to keep moisture in and prevent burning.
Can I cook Costco’s frozen lasagna in a microwave?
Yes, you can cook Costco’s frozen lasagna in a microwave, but it may take longer than conventional baking. For best results, place the lasagna in a microwave-safe dish, cover it with a microwave-safe lid or plastic wrap, and heat on high for about 10 to 15 minutes per serving. Be sure to rotate the dish halfway through for even cooking.
Keep in mind that the texture may differ from oven-baked lasagna, as microwaving can result in a softer consistency. If you prefer a firmer texture, consider using the oven method instead, or finish in the oven after microwaving to achieve a desirable texture and appearance.
How do I know when the lasagna is done cooking?
To determine if Costco’s frozen lasagna is done cooking, you can use a food thermometer to check the internal temperature. It should reach at least 165°F in the center. Additionally, the cheese on top should be melted and slightly golden, offering a visual clue that the lasagna is thoroughly cooked.
If you don’t have a thermometer, you can also check by inserting a knife in the center; if it comes out hot and clean, the lasagna is likely done. Finally, letting the lasagna rest for about 10 to 15 minutes after removing it from the oven will allow the layers to set, making it easier to serve.
Can I add extra ingredients to Costco’s frozen lasagna?
Absolutely! Many people enhance Costco’s frozen lasagna by adding ingredients such as vegetables, meats, or extra cheese before baking. Sautéed spinach, mushrooms, or bell peppers can be layered in for added flavor and nutrition. Ground beef or Italian sausage works well if you prefer a heartier meal.
Just keep in mind that adding ingredients can affect cooking time; you may need to bake it longer to ensure everything is cooked thoroughly. If you’re adding significant amounts of extra ingredients, keep an eye on the lasagna to avoid burning the top or edges; covering it with foil can prevent excessive browning.
Is it possible to freeze leftover lasagna?
Yes, you can freeze leftover Costco lasagna. Make sure to let the lasagna cool completely before transferring it to an airtight container or wrapping it tightly in plastic wrap and foil. This will help prevent freezer burn and maintain the quality of the dish when you reheat it later.
When you’re ready to enjoy the leftovers, you can thaw them in the refrigerator overnight. Reheat in the oven at 350°F covered with foil for about 25 to 30 minutes or until heated through. Microwaving is also an option; just be sure to cover it and heat in intervals for even warming.
What should I serve with Costco’s frozen lasagna?

For a more Italian-themed meal, consider serving roasted vegetables such as zucchini, asparagus, or carrots. A side of marinara sauce for dipping or drizzling can also enhance the flavors of the lasagna. The combination of sides will make for a well-rounded meal that’s sure to impress.
Can I cook Costco’s frozen lasagna in an air fryer?
