Craving an easy family dinner? This hearty Slow Cooker Cowboy Casserole with ground beef & cheesy tater tots is a crowd-pleaser. A true set-it-and-forget-it meal perfect for busy weeknights.
Ingredients
- 1.5 lbs lean ground beef 90/10 recommended
- 1 large yellow onion diced
- 3 cloves garlic minced
- 1 can (10.5 oz) condensed cream of mushroom soup
- 1 cup sour cream full-fat for best results
- 1 can (15 oz) sweet corn drained
- 2 cups shredded sharp cheddar cheese divided
- 1 tbsp Worcestershire sauce
- 1 tsp salt or to taste
- 0.5 tsp black pepper freshly ground
- 1 bag (32 oz) frozen tater tots
- 4 slices bacon cooked and crumbled, for topping (optional)
- 2 tbsp fresh chives or green onions sliced, for garnish
Instructions
- Tip #1: Brown the Beef for Maximum Flavor. In a large skillet over medium-high heat, cook the ground beef, diced onion, and minced garlic until the beef is no longer pink and the onion is softened. Drain off any excess grease thoroughly. This step is crucial for developing a rich, savory flavor base and preventing a greasy casserole.
- Prepare the Creamy Filling. In a large mixing bowl, combine the condensed cream of mushroom soup, sour cream, drained corn, 1 cup of the shredded cheddar cheese, Worcestershire sauce, salt, and pepper. Stir until everything is well incorporated.
- Combine and Layer. Add the cooked ground beef and onion mixture to the bowl with the creamy filling. Stir to combine everything. Spread this mixture evenly into the bottom of your 6-quart slow cooker.
- Tip #2: Keep the Tots Crispy. Arrange the frozen tater tots in a single, tightly packed layer over the top of the beef mixture. Do not thaw them first! Placing them on top while frozen is the secret to ensuring they bake up crispy and golden, rather than becoming soggy in the casserole.
- Slow Cook to Perfection. Cover the slow cooker and cook on LOW for 4-5 hours or on HIGH for 2-3 hours, until the filling is hot and bubbly around the edges.
- Tip #3: Add Cheese at the End. During the last 20 minutes of cooking, uncover the slow cooker and sprinkle the remaining 1 cup of cheddar cheese and the crumbled bacon (if using) over the tater tots. Replace the lid and continue cooking until the cheese is perfectly melted and gooey.
- Garnish and Serve. Turn off the slow cooker and let the casserole rest for 5-10 minutes before serving. This allows it to set up slightly. Garnish with fresh sliced chives or green onions and serve hot.
Notes
Secret Tip Recap:
1. Brown the Beef: Never skip browning the beef and onions. It builds the foundational flavor of the entire dish.
2. Frozen Tots on Top: Always use frozen tater tots and layer them on top. This is the key to a crispy, not mushy, topping.
3. Cheese Last: Add the final layer of cheese in the last 20 minutes to get that perfect, gooey melt without it burning or hardening. Storage: Store leftovers in an airtight container in the refrigerator for up to 3 days. For best results, reheat in an oven or air fryer at 375°F (190°C) until warmed through to help re-crisp the tater tots. Variations:
- Spice it up: Add a can of diced green chiles or 1/2 teaspoon of cayenne pepper to the beef mixture.
- Add Beans: Stir in a can of drained pinto or black beans along with the corn for extra fiber.
- Change the Soup: Feel free to use cream of chicken or cream of celery soup for a different flavor profile.
