How to Make Tater Tot Casserole with Ground Beef Recipe
Step 1: Prepare Your Oven and Dish
Start by preheating your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish using cooking spray or a bit of oil—this will help prevent sticking and make cleanup easier.
Step 2: Cook the Ground Beef Mixture
Heat olive oil in a large skillet over medium-high heat. Sauté the finely chopped onion and minced garlic until the onion becomes translucent, usually about 3 to 4 minutes. Next, add the ground beef, breaking it apart with your spoon, and cook until it’s no longer pink and nicely browned. Season with salt and pepper. If you’re opting for veggies like peas or green beans, stir them in now and cook for another 2 to 3 minutes. Drain off any excess fat so the casserole isn’t greasy.
Step 3: Mix the Creamy Sauce
In a separate large bowl, combine the cream of mushroom soup with the sour cream. Whisk them together until the mixture is smooth and creamy—this combo adds richness and a lovely tang that complements the beef beautifully.
Step 4: Assemble Your Casserole
Spread the cooked ground beef evenly across the bottom of your baking dish. Pour the creamy mushroom and sour cream mixture over the beef and gently spread it out. Next, sprinkle half of your shredded cheddar cheese over the top. Finally, arrange your frozen tater tots side by side in a single layer on top—this layer will become wonderfully crisp as it bakes.
Step 5: Bake Until Golden and Melty
Place the dish in your preheated oven and bake for 35 to 40 minutes, or until the tater tots are golden, crispy, and irresistibly crunchy. Pull the casserole out briefly to sprinkle the remaining cheese evenly on top, then return it to the oven for another 5 to 7 minutes until that cheese melts into a bubbly, gooey blanket.
Step 6: Let It Rest and Serve
Once out of the oven, allow the dish to cool for a few minutes. This rest time helps the casserole set up so each serving is neat and satisfying. Then dig in and savor the layers of crispy, creamy, and savory goodness.

Make Ahead and Storage
Storing Leftovers

Freezing
If you want to save some for later, this casserole freezes well. Cover the dish tightly with foil and plastic wrap, then freeze for up to two months. Thaw overnight in the fridge before reheating.
Reheating
Reheat leftovers in the oven at 350°F (175°C) until warmed through and the tater tots regain a bit of their crispness, usually about 20 to 25 minutes. Avoid microwaving if possible, as it can make the tots soggy.

What if I don’t have cream of mushroom soup?
You can substitute with cream of chicken or cream of celery soup, or even make a quick homemade white sauce for a fresh twist.
How crispy do the tater tots get in this dish?
The tater tots become satisfyingly crispy on the outside while remaining tender inside, especially after that final cheese-melting bake.
