How To Store / Freeze This Casserole
Allow the ground beef casserole to cool to room temperature before storing. This helps prevent condensation, which can make the dish soggy.
Transfer the casserole to an airtight container or wrap it tightly with aluminum foil or plastic wrap. This will keep it fresh and prevent any unwanted odors from seeping in.
Store the casserole in the refrigerator if you plan to eat it within 3-4 days. This ensures the ground beef and cheddar cheese remain at a safe temperature.
For longer storage, freeze the casserole. Place it in a freezer-safe container or wrap it securely with heavy-duty aluminum foil. Label the container with the date to keep track of its freshness.
When ready to reheat, thaw the casserole in the refrigerator overnight if it was frozen. This gradual thawing helps maintain the texture and flavor of the pasta and beef mixture.
Reheat the casserole in the oven at 350°F (175°C) until it is heated through and the cheese is bubbly again. This usually takes about 20-25 minutes. Cover with foil if the top starts to brown too quickly.
For a quicker option, you can reheat individual portions in the microwave. Place a serving on a microwave-safe plate, cover with a microwave-safe lid or another plate, and heat on high for 2-3 minutes, or until hot.
Always check the internal temperature of the reheated casserole to ensure it reaches at least 165°F (74°C) for safe consumption.
How To Reheat Leftovers
Preheat your oven to 350°F (175°C). Place the leftover ground beef casserole in an oven-safe dish. Cover it with aluminum foil to prevent it from drying out. Bake for about 20-25 minutes or until heated through.
For a quicker option, use the microwave. Transfer a portion of the casserole to a microwave-safe dish. Cover it with a microwave-safe lid or a damp paper towel. Heat on medium power for 2-3 minutes, stirring halfway through to ensure even heating.
If you have an air fryer, preheat it to 350°F (175°C). Place the casserole in an air fryer-safe dish. Heat for 10-15 minutes, checking halfway through to ensure it doesn't overcook.
For stovetop reheating, place the casserole in a skillet over medium heat. Add a splash of water or broth to keep it moist. Cover and heat for about 10 minutes, stirring occasionally until warmed through.
If you prefer a crispy topping, reheat the casserole in the oven uncovered for the last 5 minutes of heating. This will help the cheddar cheese get bubbly and slightly browned.
