Let’s look at the different methods you can use to reheat a green bean casserole.
Slow Cooker
You. can reheat a green bean casserole by putting it into a crockpot or slow cooker on low heat for 1 to 2 hours, or high heat, for 30 minutes to 1 hour.
Please note that the time may vary depending on your specific slow cooker. Some heat faster than others.
The idea is that you simply want to reheat it in the slow cooker until it is warmed through. Reheating it in the slow cooker is ideal, especially if your oven is full.
Microwave
Another way to reheat your leftover green bean casserole is in the microwave. Microwaving it is quick and easy but could make the French-fried onions on top of your casserole mushy, rather than crispy.
However, if you’re looking for the fastest method, then microwaving your green bean casserole leftovers is likely going to be the fastest option.
How to Reheat Green Bean Casserole in Microwave
To reheat your green bean casserole in the microwave, first transfer the green bean casserole into a microwave-safe bowl, or another type of microwave-safe dish.
Cover the casserole with a damp paper towel, then microwave for 2 to 5 minutes, or until the casserole is warmed all the way through.
Please note that the microwave time may vary depending on your specific microwave.
Oven
The best way, in our opinion, to reheat a green bean casserole is to reheat it in the oven. When doing this, it’s important that you use a room-temperature casserole dish, so that you’re not putting a cold glass dish into a hot oven.
You can also use a lid to cover the casserole dish, or cover with aluminum foil if you wish to cover it. Otherwise, you can simply leave it open, especially if you want the French-fried onions to become crispy.
If you have to use a cold dish in the oven, then you will want to place the cold dish into a cold oven, most of the chances of cracking the dish are much less.
How to Reheat Green Bean Casserole in the Oven
To reheat a green bean casserole in the oven, preheat the oven to 350°F.
Transfer the leftover green bean casserole into a casserole dish, if desired add additional French-fried onions to the top.
Cover the casserole dish with a lid, or aluminum foil if desired, then place the casserole dish into the oven, and bake for approximately 15 to 20 minutes or until the green beans are warmed through.
If you chose to cover the casserole dish, you may want to remove the lid, for the last five or eight minutes of cooking, so that the French-fried onions become crispy.
After the green bean casserole is warmed all the way through, remove it from the oven, serve, and enjoy!
Stovetop
Another way you can reheat leftover green bean casserole is in a pan on the stovetop. This method is less common but can be done if necessary.
You would likely want to use a cast-iron skillet, Dutch oven, or another type of pan that heats evenly.
Place it over medium heat and allow it to warm for a few minutes until the casserole is warmed all the way through.
When the casserole has heated all the way through, remove it from the stovetop, serve, and enjoy.
Air Fryer
Another way you can reheat your green bean casserole is in the air fryer. To do this you will need an air fryer that is large enough to fit a casserole dish or another type of dish.
Please note that this method is not ideal for everyone, because some air fryers are much too small to reheat more than one serving.
How to Reheat Green Bean Casserole in Air Fryer
First, to reheat green bean casserole in the air fryer, you will want to make sure that you have a container small enough to fit into your air fryer. Then make sure that the container is oven safe.
When you have found an oven-safe dish, that is safe to use in your air fryer, transfer the green bean casserole into the container.
If your air fryer has a re-heat setting, we recommend using that. Preheat your air fryer to 350°F, on the reheat setting if possible.
When preheated, add your green bean casserole to the air fryer basket. The amount of time that it takes to reheat your leftover green bean casserole in the air fryer will vary depending on your specific air fryer.
It could take anywhere between 5 to 10 minutes for it to warm all the way through. We recommend checking on your green beans occasionally until they are warmed through.
Once they are warmed all the way through, remove them from the air fryer, then serve, and enjoy.
Please note: you may want to cover your green bean casserole with aluminum foil before reheating it in the air fryer depending on how close your air fryer basket is to the heating coil.
If you choose to cover it with aluminum foil, and we recommend poking holes in the foil, so the air can still circulate into your green beans.
Toaster Oven
Another way you can reheat leftover green bean casserole is in a toaster oven. A toaster oven is very similar to an air fryer. Before reheating green bean casserole in your toaster oven, you will want to make sure that you have a dish that can safely be heated in your toaster oven and one that fits inside the toaster oven.
How to Reheat Green Bean Casserole in the Toaster Oven
First, transfer your green beans into an oven-safe dish that fits into the toaster oven.
Preheat the toaster oven to 350°F.
Cover the green bean casserole with aluminum foil, then place it into the preheated toaster oven for 4 to 8 minutes depending on your specific toaster oven.
When the green beans are heated all the way through, we recommend removing the aluminum foil from the top of the green bean casserole and continuing cooking for another 1 to 3 minutes so that the French-fried onions on top can become crispy.
After it is warmed all the way through, remove the green bean casserole from the toaster oven, serve, and enjoy.
Instant Pot
While green bean casserole can be made in an instant pot, we do not recommend reheating green bean casserole in an instant pot, because it doesn’t typically turn out quite right.
How to Reheat a Frozen Casserole
You can freeze leftover green bean casserole, for longer storage if desired. After the green bean casserole has been frozen, you can also reheat the frozen casserole.

In the Oven. If you’re able, storing the casserole dish in the oven, after the oven has been turned off is a great way to keep it warm until you serve the side dish.
In the Microwave. Another way to store leftover green bean casserole and keep it warm until you’re ready to serve it is to place it in the microwave. Do not run the microwave, instead simply close it in the microwave, with the microwave off for a few minutes until you are ready to serve the casserole.
Covered in Foil. Another way you can keep the green bean casserole warm for a few minutes so that all the food is ready at one time is to cover the green bean casserole with aluminum foil. This helps trap the heat inside the container.
