No one really wants to eat room-temperature casseroles. Today, we'll break down all the different methods so you can store food safely and enjoy a hot meal while relaxing with friends and family.
Keep a Casserole Warm (with Electricity)
Have an electrical outlet close by? Then use these methods.
Oven or toaster oven
Using the oven or a large toaster oven is a fool-proof way to keep your casserole dish out of the danger zone. Set the temperature to 200 degrees F and keep the food inside until you're ready to serve it.
No oven? No problem. Dishes made in the crock pot are even easier to keep warm. Set the slow cooker to the warm setting, and you're good to go. I like that the food stays hot while serving, too!
Electric warmer/buffet table tray
If you entertain often, you might invest in an electric warmer/buffet table tray. These surfaces prevent heat loss and keep potluck food hot—just set your dish on, and it'll stay nice and warm.
Some hosts get a little crafty by setting a plate on top of an electric blanket. While this won't generate enough heat to keep large casseroles warm, it's a good way to create a makeshift "hot plate" for rolls, cookies, or other small items. Be sure to use a heat-proof plate, like ceramic.
Keep a Casserole Warm While On the Go
Sometimes you don't have access to electricity. That's when these methods are the way to go.
Thermal cookers are sort of like cordless crockpots. They're a great option for keeping food hot while transporting it to a potluck or picnic.
Insulated carrier/casserole carrier
If your baking dish came with a casserole carrier, it's likely an insulated carrier! Dig it out from the back of your pantry and put it to use—the special material is designed to keep heat from escaping.
Coolers/ ice chests
Coolers aren't just for cold beer. The same insulating material that keeps cold drinks chilly will also keep hot food warm.
Most people recommend you "preheat" your cooler by pouring in some hot (not boiling) water. Let it sit, then dry it out. Finally, add a heating pad or hot water bottle, place your food in carefully, and shut the lid.
You can also use heating packs on their own, along with a few towels and tin foil. Completely wrap the dish with foil—shiny side facing the food. Then, place it carefully on a few flat hot packs and wrap everything in a spare towel for extra insulation.
Consider using some chafing dishes for your potluck dinner. These foil containers are filled with water and stacked over a small flame to keep food steaming hot for an extended period of time.
💭 Things to know
Expert Tip: When setting up for a potluck, keep all the warm foods in one spot next to each other. Place the cold foods together farther away.
- If food sits with an internal temperature below 140 degrees F for longer than two hours, you risk getting sick. Throw it away.
- The easiest way to double-check the internal temp of a casserole is with a food thermometer—I recommend instant-read for quick results.
- Keeping food in the oven for a long time to warm can dry it out. Cover it with a layer of aluminum foil to keep the moisture inside.
- Most slow and rice cooker brands recommend using the warm setting for up to four hours. Any longer, and you can dip out of the safe zone.
- If you have a crispy topping for your casserole, you may opt to add it just before serving. Crisp ingredients tend to get soggy as they sit.
This depends on the temperature of your casserole, how large it is, and the carrier itself. On average, insulated carriers keep food hot for about an hour.
For extended periods of time, I recommend using the oven or chafing dishes. Not all of the methods in this post will keep your food at a safe temperature all day long.
Use what you already have! Take advantage of the oven or a crockpot. If you don't have access to those, try the foil, old towel, and heating pad trick to keep it warm for a bit.
It sure does! Foil works by reflecting heat back into the food. Remember this tip: the shiny side should face hot food to keep it hot. On the other hand, the dull side should face cold food to keep it cold!
If you have a lot of moisture in your dish and are worried about it getting mushy, you may want to leave the lid slightly off. However, if you want to prevent a dish from drying out, keep it covered.
