Refrigerated lasagna is a delicious and convenient make-ahead dish that can be enjoyed for days after it’s been prepared. But how long should you heat up refrigerated lasagna to ensure it’s thoroughly heated and safe to eat? The answer depends on a few factors, including the size of the lasagna and the type of oven you’re using.
In general, it’s recommended to heat up refrigerated lasagna in the oven for about 20-30 minutes. This allows enough time for the lasagna to heat through and for the cheese to become melty and bubbly. However, if you’re using a smaller portion of lasagna, it may take less time to heat through. On the other hand, if you’re reheating a large lasagna, it may take longer for the center to heat up.
When heating up refrigerated lasagna, it’s important to use a preheated oven set to a moderate temperature, usually around 350°F (175°C). This allows for an even heat distribution and ensures that the lasagna is heated thoroughly without burning the edges.
Before reheating your refrigerated lasagna, ensure that it’s properly stored in an airtight container or covered tightly with aluminum foil. This helps to retain moisture and prevent the lasagna from drying out during the reheating process. Once heated, the lasagna should be piping hot throughout, with an internal temperature of at least 165°F (74°C), to ensure it’s safe to eat.
Best Methods for Heating Lasagna
Heating up refrigerated lasagna can be a delicate process. If not done properly, you may end up with unevenly heated or dried out lasagna. Here are a few of the best methods for heating lasagna to ensure a delicious and evenly heated meal:
1. Oven Method:
The oven method is ideal for large portions of lasagna. Preheat your oven to 350°F (175°C). Place the lasagna in an oven-safe dish and cover it with aluminum foil to prevent it from drying out. Bake it in the oven for about 20-30 minutes, or until it is heated through. If you prefer a crispy top, remove the foil during the last 10 minutes of cooking.
2. Stovetop Method:
If you’re in a rush and don’t have much time, the stovetop method is a great option. Place a non-stick skillet or pan over medium heat. Cut the lasagna into individual portions and place them in the skillet. Add a few tablespoons of water or sauce to the pan to create steam and prevent sticking. Cover the skillet and let it cook for about 10-15 minutes, or until heated through. Make sure to stir occasionally to heat the lasagna evenly.
