When you want a hearty meal and a delicious dish that you can make all in one pan, casseroles are the way to go. This dinner staple usually contains a mixture of protein, starch, and veggies, and it can be topped with anything from cheese to potato chips. The varieties are almost endless, so no matter what types of foods you like best, you’re sure to find a casserole that you love.
From cheesy pasta dishes to vegetable casseroles, to hearty meat and potato mixtures, there are casseroles for every taste and every occasion. There are also a variety of ways to cook and reheat your casseroles, and if you’re new to preparing this dish, you might be wondering how to make sure your casseroles are cooked perfectly every time.
The heating method for your casserole is going to depend on a few factors, like whether you’re starting with raw meat and whether you’re cooking the casserole for the first time, reheating leftovers, or heating a frozen casserole. No matter what type of casserole you’re making, you’ll want to be sure that the dish reaches a safe internal temperature, but isn’t cooked so long that it dries out. Below, you’ll find some easy tips for getting all kinds of casseroles perfectly cooked or reheated.

Tools
To start, you’ll need a few handy tools that will help you heat your dishes and monitor the temperature as they’re cooking. An instant-read thermometer is going to be your best friend, and if you don’t have one, I highly recommend making the purchase.
Instant-read digital thermometers are the most popular type of food thermometer. They’re designed to be inserted into the thickest part of the food and will instantly tell you the internal temperature, so it’s the best way to ensure that your food is fully cooked, with no guessing involved. Not only will this tool help you with your casseroles, but you’ll get plenty of use out of it when cooking any type of meat or seafood dishes. You can pick up an instant-read thermometer for less than $20 on Amazon, and I promise that it’s well worth the investment.
If you’re planning to bake casseroles often, you’ll also want to invest in a good quality casserole baking dish that retains heat well and distributes it evenly throughout the dish. Ceramic and glass are good choices for retaining heat, and either of these is likely to be a microwave-safe dish as well, so you won’t have to transfer your casserole to another container if you want to reheat it later in the microwave.
Heating for the First Time
When you’re making your casserole for the first time, most casserole recipes will call for you to cook the meat separately before adding it to the casserole. Some recipes may call for raw meat to be added directly to the casserole dish, and this can work as long as you ensure that the meat reaches a safe internal temperature. However, this is definitely a trickier method, and one that I wouldn’t attempt without a food thermometer. You also run the risk of your veggies and starches getting overcooked by the time your meat reaches a safe temperature.
But regardless of when you cook your meat, you’ll want to be sure that it has been cooked well enough to destroy any potentially harmful bacteria, so let’s talk about the correct internal temperatures for various types of meat.
According to the United States Department of Agriculture, the minimum safe internal temperature for chicken and poultry is 165 degrees F, while ground meat and eggs are listed at 160 degrees Fahrenheit, and fish and shellfish are listed as 145 degrees F. The USDA also has a separate category for casseroles in which it lists the safe minimum internal temperature as 165 degrees F. To be sure your casserole is heated thoroughly, I’d recommend following the general casserole guidelines and making sure that your internal temperature reaches 165 F as a general rule, regardless of the contents of your casserole.
Tips for Taking an Accurate Reading
- When checking the temperature of your dish, try to insert the thermometer as close to the center of the casserole as possible. Readings taken at the edges of the casserole may give you an inaccurate reading, as the middle may still be undercooked.
- Wait a few seconds for the temperature to stabilize before taking the reading. If you remove the thermometer too quickly, this can give you an inaccurate reading as well.
Reheating a Leftover Casserole
One of the best things about casseroles is that they make great leftovers. If you’re lucky, you’ll get several meals out of your casserole and if reheated properly, they’ll taste just as good the next day as when they were freshly prepared.
The air fryer or oven methods generally work best for reheating casserole leftovers, as they’ll do the best job keeping toppings like bread crumbs perfectly crisp and cheese melted evenly. An oven temperature of 350 degrees F and a cooking time of 20-30 minutes is suitable for reheating most casseroles, but you’ll want to make sure that your internal temperature reaches 165, just like when you first prepared it. Also, it’s a good idea to remove it from the refrigerator and let it come to room temperature, then remove any plastic wrap and cover it with aluminum foil before placing it in the hot oven.
Heating from Frozen
If you made an extra casserole to freeze for later, good for you! There are tons of great make-ahead casseroles that give you an easy meal to pop in the oven at dinner time on those busy weeknights. But you’ll definitely want to plan ahead if your casserole is frozen. For best results, you should let it thaw in the refrigerator overnight and then sit on the counter until it comes to room temperature. If you don’t have enough time to let it thaw overnight, you can also use your microwave oven to defrost it.
Store-Bought Casseroles
If you’re buying a premade casserole, it will likely come with instructions on the best way to heat it and the preferred oven temperature. If it doesn’t, you can go with the general guidelines above. And even if the instructions don’t specify an internal temperature for the casserole, be sure to use your food thermometer to verify that the center has reached 165 degrees F.
Other Tips
- Avoid a dry casserole by storing leftovers in an airtight container
- Pay attention to portion size – smaller portions will take less time to heat or reheat
I hope these tips have provided all the information you need to cook and reheat your casseroles with confidence. Now, let’s get cooking with a few of my favorite casserole recipes!
