How To Store / Freeze This Breakfast Casserole
To store the tater tot breakfast casserole in the refrigerator, first allow it to cool completely. This prevents condensation and sogginess. Once cooled, cover the baking dish tightly with aluminum foil or transfer the casserole to an airtight container. It will keep well in the refrigerator for up to 3-4 days.
For freezing, let the casserole cool to room temperature. Cut it into individual portions for easier reheating. Wrap each portion tightly in plastic wrap and then place them in a freezer-safe bag or container. Label with the date to keep track of freshness. The casserole can be frozen for up to 2-3 months.
When ready to reheat from the refrigerator, preheat your oven to 350°F (175°C). Place the desired portion in an oven-safe dish and cover with aluminum foil. Heat for about 20-25 minutes or until warmed through.
To reheat from frozen, you have two options. For a quicker method, you can use the microwave. Unwrap the portion and place it on a microwave-safe plate. Microwave on high for 2-3 minutes, checking and stirring halfway through. For the best texture, reheat in the oven. Preheat to 350°F (175°C), place the frozen portion in an oven-safe dish, cover with aluminum foil, and bake for 30-35 minutes or until hot and bubbly.
If you prefer a crispier top, remove the aluminum foil during the last 10 minutes of reheating in the oven. This will allow the cheese to melt and brown nicely.
Always check the internal temperature of the reheated casserole to ensure it reaches at least 165°F (74°C) for safe consumption.
