It’s also highly adaptable — add veggies for nutrition or swap meats for what you have on hand. Perfect for weeknights, casual gatherings, or when you want a simple, make-ahead dinner that reheats well.

How this recipe comes together
- Brown and season the ground beef with onion and garlic to build savory depth.
- Stir cream of mushroom soup, sour cream, milk, and most of the cheese into the beef for a rich, creamy filling.
- Spread the filling into a baking dish, top with an even layer of tater tots, sprinkle the remaining cheese, and bake until the tots are golden and the center bubbles.
- Garnish with fresh chives and diced red pepper for color and brightness.

Gather these items
What you’ll need (with quick notes and substitutions)
- 1 lb ground beef — lean or 80/20 works; drain excess fat if needed.
- 1 small onion, diced — yellow or sweet onion adds subtle sweetness.
- 1 clove garlic, minced — or 1/2 tsp garlic powder.
- 1 can cream of mushroom soup — swaps: cream of chicken or celery.
- 1/2 cup sour cream — plain Greek yogurt works if you want tang and protein.
- 2 cups shredded cheddar cheese — sharp or mild; a mix of cheddar and Monterey Jack melts nicely.
- 1/2 cup milk — any milk will do; use a splash more for looser filling.
- 1 bag frozen tater tots (32 oz) — you won’t need all if you prefer a thinner layer; 24 oz is fine.
- 1/4 cup diced red bell peppers (optional, for garnish) — adds color and sweetness.
- 2 tbsp chopped chives (for garnish) — fresh herbs brighten the rich casserole.
- Salt and pepper to taste.

Step-by-step instructions
Preparation
- Preheat the oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish.
- Thaw any frozen tots slightly if they’re very icy; a few minutes on the counter works.
Cooking
3. In a large skillet over medium heat, brown 1 lb ground beef with the diced onion until the beef is fully cooked and the onion is translucent, about 6–8 minutes.
4. Add the minced garlic and cook 30 seconds more until fragrant. Season generously with salt and pepper.
5. Remove excess fat if necessary. Stir in 1 can cream of mushroom soup, 1/2 cup sour cream, 1/2 cup milk, and 1 1/2 cups of shredded cheddar cheese. Mix until smooth and heated through. Taste and adjust seasoning.
6. Spread the beef mixture evenly into the prepared baking dish.
7. Arrange tater tots in a single layer over the beef mix. Sprinkle the remaining 1/2 cup cheese on top of the tots.
8. Bake uncovered for 25–35 minutes, or until the tater tots are golden brown and the filling is bubbling. For extra crispness, finish under the broiler for 1–2 minutes—watch closely.
Serving
9. Let the casserole rest 5–10 minutes before slicing so it sets. Garnish with diced red bell pepper and chopped chives. Serve warm.
Safety note: Ground beef should reach an internal temperature of 160°F (71°C) during cooking. Use a thermometer if in doubt.
Best ways to enjoy it
- Pair with a crisp green salad or steamed broccoli to balance richness.
- Serve with pickled jalapeños or a squeeze of hot sauce for a tangy contrast.
- For a brunch version, top with a fried egg per portion.
- Plate it family-style straight from the baking dish for casual gatherings, or spoon portions onto warm plates and finish with a sprinkle of fresh chives for a restaurant touch.
How to store & freeze
- Refrigerate: Cool the casserole to room temperature, cover tightly, and refrigerate for up to 3–4 days.
- Reheat: Reheat individual portions in the microwave for 1–2 minutes until hot. For the best texture, reheat a whole or partial casserole in a 350°F oven covered with foil for 20–30 minutes, then uncover to crisp the tots.
- Freeze: Assemble and bake, or assemble raw and freeze. To freeze baked: cool completely, wrap tightly, and freeze up to 3 months. To bake from frozen: thaw in the fridge overnight, then bake at 375°F until heated through; if baking from frozen raw, add 20–30 minutes to the bake time and cover with foil until hot, then uncover to brown.
Food safety tip: Do not leave the casserole at room temperature for more than 2 hours.
Helpful cooking tips
- Drain excess grease after browning the beef to prevent a runny filling.
- Don’t over-stir the filling once cheese is added — stir enough to combine, then transfer to the dish to preserve a slight structure.
- For extra flavor, sauté the onions in a tablespoon of butter until golden before adding beef.
- Want a lighter version? Use ground turkey, Greek yogurt instead of sour cream, and reduced-fat cheese.
- If your tater tots brown too fast, tent the dish with foil mid-bake.
Recipe variations
- Vegetarian: Swap beef for a cooked lentil and mushroom mixture and use vegetable cream soup.
- Tex-Mex: Add a packet of taco seasoning to the beef, mix in corn and black beans, and top with pepper jack cheese.
- BBQ twist: Use shredded cooked chicken tossed in BBQ sauce instead of ground beef and top with smoked cheddar.
- Potato swap: Use frozen hash brown patties or shredded potatoes in place of tater tots for a different texture.
Your questions answered
Q: How long does this casserole take from start to finish?
A: About 45–60 minutes total — 10–15 minutes active prep, 25–35 minutes baking, plus a few minutes to rest.
Q: Can I make this ahead?
A: Yes. Assemble the casserole and refrigerate (covered) for up to 24 hours before baking. If assembling and freezing, see the storage section for thawing and bake times.
Q: Is this safe for kids and picky eaters?
A: Absolutely. The flavors are mild and familiar; the tater tot topping is usually a hit. You can hide finely chopped veggies in the filling for extra nutrition.
Q: Can I reduce calories without losing texture?
A: Use lean ground beef or ground turkey, substitute Greek yogurt for sour cream, and choose reduced-fat cheese. Keep in mind lower-fat cheeses may produce a slightly different melt.
Q: My filling is watery — what went wrong?
A: Possible causes: excess fat not drained, too much milk, or a watery soup brand. Drain beef fat, reduce milk slightly, or add an extra 1/4 cup cheese or 1/4 cup breadcrumbs to help thicken.
