The answer is a resounding NO. You should always remove the plastic film before cooking your Stouffer’s lasagna. Leaving it on can lead to uneven cooking, potential melting of the plastic into the food, and potentially harmful chemical leaching.
Why Removing the Film is Crucial
Stouffer’s lasagna is a staple in many households, offering a convenient and comforting meal. However, achieving that perfect, bubbly cheese and perfectly heated interior requires understanding the proper cooking instructions. The plastic film, while seemingly harmless, plays a specific role during freezing and shipping: to protect the lasagna’s surface. It’s not designed for oven temperatures.
Potential Dangers of Cooking with the Film On
- Melting: High oven temperatures can cause the plastic film to melt, potentially contaminating the lasagna with plastic particles.
- Uneven Cooking: The film acts as a barrier, preventing heat from properly penetrating the top layer of the lasagna. This can result in a partially frozen center or a burnt exterior.
- Chemical Leaching: Even if the plastic doesn’t visibly melt, chemicals from the film can leach into the food at high temperatures, posing a potential health risk. While the film may be food-grade at low temperatures, it’s not intended for sustained high heat exposure.
- Altered Taste and Texture: Even without visible melting, the film can subtly alter the taste and texture of the lasagna, preventing you from enjoying its full flavor.
The Right Way to Cook Stouffer’s Lasagna
- Remove the Plastic Film: This is the most crucial step. Discard the film before preheating your oven.
- Preheat Your Oven: Follow the instructions on the packaging for the correct temperature and cooking time, usually around 375°F (190°C).
- Bake Covered: Cover the lasagna with aluminum foil for the majority of the cooking time to prevent the top from burning.
- Uncover and Bake: Remove the foil for the last portion of the cooking time to allow the cheese to brown and bubble.
- Check for Doneness: Use a fork to check the center of the lasagna. It should be hot and bubbly throughout.
- Let it Rest: Allow the lasagna to rest for 10-15 minutes before cutting and serving. This allows the cheese to set and the flavors to meld.
Stouffer’s Lasagna FAQs: Your Burning Questions Answered
This section addresses common questions and concerns regarding Stouffer’s lasagna, ensuring a foolproof cooking experience.
1. Can I Cook Stouffer’s Lasagna in the Microwave?
While Stouffer’s doesn’t recommend cooking their large lasagna in the microwave, some of their smaller individual portions are designed for microwave cooking. Always refer to the packaging for specific instructions. If microwaving, be sure to follow the designated microwaving times and use a microwave-safe dish.
2. What Happens if I Accidentally Cooked it with the Film On?
If you accidentally cooked the lasagna with the film on, remove the lasagna from the oven immediately. Carefully peel off the film. Inspect the lasagna thoroughly for any signs of melting or contamination. If you see any melted plastic or suspect chemical leaching, it’s best to discard the lasagna.
3. Can I Use a Different Type of Cover Than Aluminum Foil?
Yes, you can use a lid specifically designed for oven use that fits the baking dish. Glass lids or silicone covers are suitable alternatives to aluminum foil. Ensure the lid is oven-safe at the required temperature.
4. How Long Should I Cook Stouffer’s Lasagna?
Cooking time varies depending on the size of the lasagna and your oven’s performance. Always refer to the packaging for specific instructions. Generally, it takes between 55 minutes to 1 hour and 30 minutes for a large lasagna to cook thoroughly. Use a food thermometer to ensure the internal temperature reaches 165°F (74°C).
5. My Lasagna is Still Frozen in the Middle. What Should I Do?
If your lasagna is still frozen in the middle, return it to the oven, cover it with foil, and continue baking for an additional 15-30 minutes. Check the internal temperature again to ensure it reaches 165°F (74°C). In some cases, it may be necessary to lower the oven temperature slightly to prevent the top from burning while the center cooks.
6. Can I Cook Stouffer’s Lasagna from Frozen?
Yes, Stouffer’s lasagna is designed to be cooked from frozen. Do not thaw it before cooking. Thawing can affect the texture and cooking time, potentially leading to an unevenly cooked lasagna.
7. What’s the Best Way to Prevent the Cheese from Burning?
The best way to prevent the cheese from burning is to cover the lasagna with aluminum foil for the majority of the cooking time. Only remove the foil during the last 15-20 minutes to allow the cheese to brown and bubble. If the cheese starts to brown too quickly, you can carefully tent the foil over the top of the lasagna.
8. Can I Add Extra Cheese or Other Ingredients to Stouffer’s Lasagna?
Yes, you can definitely customize your Stouffer’s lasagna. Adding extra cheese, vegetables, or meat is a great way to personalize it. Just be mindful of the increased volume, which may require a slightly longer cooking time. Add any extra ingredients during the last 30 minutes of cooking.
9. How Do I Store Leftover Stouffer’s Lasagna?
Store leftover Stouffer’s lasagna in an airtight container in the refrigerator for up to 3-4 days. To reheat, you can use the microwave, oven, or stovetop.
10. Can I Refreeze Cooked Stouffer’s Lasagna?
While technically possible, refreezing cooked Stouffer’s lasagna is not recommended. Refreezing can significantly affect the texture and flavor of the lasagna, making it less enjoyable.
11. Are Stouffer’s Lasagnas Gluten-Free?
Stouffer’s offers a gluten-free lasagna option. Check the packaging carefully to ensure you are purchasing the gluten-free variety. The regular Stouffer’s lasagna contains wheat and is not suitable for individuals with gluten sensitivities or celiac disease.
12. Is the Packaging Recyclable?
