How to Reheat Casserole in the Oven
Casseroles are great because the leftovers are just as good as the original meal. Casseroles are also versatile and can be made with a variety of ingredients for any meal of the day.
While they are most often served during brunch, lunch, or dinner, they may also be served during breakfast time.
The leftovers for a casserole can be reheated to make them just as good as when they just came out of the oven. However, for the best results there are some very specific ways to reheat the casserole.
1. Reheating Breakfast Casserole
Breakfast casserole is great in the morning. It gives a full meal offering your choice of breakfast meat, eggs, cheese, and breading that gives a sweet and savory concoction that will keep you fed for many mornings. Reheating this meal can be an important part to how it is enjoyed.
Reheating in the Oven
This is the traditional way to reheat your casserole, and probably the longest way. However, it is the most satisfying. Preheat the oven to 350 degrees Fahrenheit.
While that is heating, you should place your casserole in a container that is appropriate for the oven.
Assess whether your casserole has separated or not. This can be done by looking to see if there is moisture around the casserole.
If it is not separated, leave the container covered to lock in moisture. However, if it has separated you should uncover the casserole so it doesn’t get soggy or chewy.
Let the breakfast casserole cook for about 30 minutes. This time is actually very subjective; you should heat it until you are satisfied with the temperature.
However, because it has eggs, you should leave it in until you are sure it is hot enough to kill off any bacteria.
Once it is steaming hot, enjoy it straight out of the container you served it in or serve it however you desire. Make sure you leave it to sit for 5 to 10 minutes.
2. Reheating Vegetable Casserole
These are probably the healthiest option for making casserole. They can be made with a variety of vegetables and cheeses that can make a delicious mixture of ingredients.
Properly heating the leftover casserole from last night’s dinner will ensure you enjoy it as if it has just left the oven.
Reheating in the Oven
Unlike the breakfast casserole, the vegetable casserole can withstand higher temperatures and is more likely to get soggy while it is stored in the refrigerator.
You should preheat your oven to 400 degrees Fahrenheit as a result. This higher temperature will also save you time.
Depending on your preferences, you can either reheat it covered or uncovered. Uncovering it will dry out the casserole.
Place it in an oven safe container and leave it in the oven after it has preheated. Depending on the size, you should leave it cooking for 10 to 20 minutes.
After it has cooked long enough, you can check the temperature with a thermometer. The internal temperature should be at least 165 degrees Fahrenheit. If it is less than that temperature, then you should leave it in for more time as you see fit.
Once it is done, leave it out for five to ten minutes before serving.
Both breakfast and vegetable casseroles can also be reheated in the microwave. However, this way of heating can be more prone to contamination and the heating is less even than you would like. However, in a pinch a microwave is always a great option.
Place your casserole in a microwave safe container. Place it in the microwave for 2 to 5 minutes depending on the size of the casserole. You can check the temperature as it cooks to see if the internal temperature has reached at least 165 degrees Fahrenheit.
After the microwave is done and it has reached the correct temperature, you can serve your casserole. Let it sit for a few minutes before serving.
