Ingredients For Tater Tots Casserole Recipe
Ground beef: Provides the main protein and a rich, savory flavor.
Cream of mushroom soup: Adds creaminess and depth to the casserole.
Sour cream: Enhances the creaminess and adds a slight tang.
Shredded cheddar cheese: Melts to create a gooey, cheesy topping.
Frozen tater tots: Forms a crispy, golden layer on top.
Chopped onion: Adds flavor and texture to the ground beef mixture.
Salt and pepper: Seasonings to taste.
Technique Tip for This Recipe
When browning the ground beef and onion in the skillet, make sure to break the beef into small, even pieces to ensure it cooks evenly. This will also help the onion to soften more uniformly. Draining any excess fat is crucial to avoid a greasy casserole. For an extra layer of flavor, consider adding a splash of Worcestershire sauce or a pinch of garlic powder to the beef mixture. When spreading the frozen tater tots on top, arrange them in a single, even layer to ensure they become golden brown and crispy during baking.

How to Store / Freeze This Casserole
- To store your tater tots casserole, allow it to cool completely at room temperature. Once cooled, transfer it to an airtight container or cover the baking dish tightly with aluminum foil or plastic wrap. Refrigerate for up to 3-4 days.
- For longer storage, you can freeze the casserole. After cooling, wrap the entire dish in plastic wrap and then a layer of aluminum foil to prevent freezer burn. Alternatively, portion the casserole into individual servings and place them in freezer-safe containers or resealable plastic bags. Label with the date and freeze for up to 2-3 months.
- When ready to enjoy your frozen tater tots casserole, thaw it in the refrigerator overnight. This slow thawing process helps maintain the texture and flavor of the dish.
- Reheat the thawed casserole in a preheated oven at 350°F (175°C) for about 20-25 minutes, or until heated through. If reheating from frozen, cover the dish with foil and bake for 45-50 minutes, then remove the foil and bake for an additional 10-15 minutes to crisp up the tater tots.
- For a quick reheat, you can also use the microwave. Place a portion of the casserole on a microwave-safe plate, cover with a microwave-safe lid or another plate, and heat on medium power for 3-5 minutes, or until hot. Stir halfway through to ensure even heating.
- To keep the tater tots crispy when reheating, consider using a toaster oven or air fryer. Preheat the appliance to 350°F (175°C) and heat the portion for 10-15 minutes, checking occasionally to avoid overcooking.
How to Reheat Leftovers
Preheat your oven to 350°F (175°C). Place the leftover tater tots 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. Remove the foil for the last 5 minutes to let the tater tots crisp up again.
For a quicker method, use the microwave. Place a portion of the casserole on a microwave-safe plate. Cover it with a microwave-safe lid or another plate to retain moisture. Heat on medium power for 2-3 minutes, checking halfway through. Stir if necessary and continue heating until hot.

On the stovetop, use a non-stick skillet over medium heat. Add a splash of broth or water to the skillet to prevent sticking. Place the casserole in the skillet and cover with a lid. Heat for about 10 minutes, stirring occasionally, until warmed through.
