Ingredients
- 1 1/2 lb (680 g) ground beef
- 1 medium onion, diced
- 2 cloves garlic, minced
- 1 can (10.5 oz) condensed cream of mushroom soup
- 1/2 cup sour cream
- 2 cups frozen mixed vegetables (corn, peas, green beans)
- 2 cups shredded cheddar cheese, divided
- 1 bag (32 oz) frozen tater tots
- 1 tsp garlic powder
- Salt and black pepper to taste
Instructions
- Heat the oven to 375°F (190°C) and grease a 9x13-inch baking dish. Brown the beef and onion in a large skillet over medium-high heat, 6 to 7 minutes, then stir in the garlic.
- Drain the fat, then stir in the cream of mushroom soup, sour cream, garlic powder, salt, and pepper. Fold in the frozen vegetables and 1 cup of the cheddar cheese.
- Spread the beef mixture evenly in the baking dish. Arrange the tater tots in neat rows over the top with no gaps, so the crust bakes up golden and crunchy.
- Bake 30 minutes until the tots are starting to crisp and the filling bubbles at the edges.
- Sprinkle the remaining cheddar over the tots and bake 10 more minutes until the cheese is melted and the tots are deeply golden.
- Rest 10 minutes so the layers set, then scoop and serve. A dollop of sour cream on top is never wrong.
Pro tips
- Arrange the tots in a single tight layer; gaps in the topping let the filling bubble through and get soggy.
- Do not thaw the vegetables; they cook through in the oven and hold their texture better.
- Season the beef mixture boldly, since the creamy soup mutes flavors as it bakes.
- Reheat leftovers in the oven so the tots turn crispy again.
Frequently asked questions
Can I assemble tater tot casserole ahead of time?
Yes. Assemble the beef layer, cover, and refrigerate up to a day ahead. Add the tots just before baking so they crisp properly.
What can I use instead of cream of mushroom soup?
Cream of chicken soup or a homemade white sauce with mushrooms both work in the same amount.
Can I use fresh potatoes instead of tater tots?
You can, but they need par-cooking first and will not get quite as crisp. Frozen tots are the classic choice.
How long do leftovers keep?
Up to 4 days refrigerated. Reheat in the oven so the tots crisp up again instead of going soft in the microwave.
