Ingredients

- ½ cup sour cream
- 1 small onion, diced
- 2 cups shredded cheddar cheese, divided

How to Make Tater Tot Casserole with Ground Beef
Step 1: Preheat the Oven
Preheat your oven to 375°F (190°C). Grease a 9×13-inch casserole dish with butter or cooking spray.
Step 2: Cook the Ground Beef
In a large skillet over medium heat, brown the ground beef, breaking it up as it cooks. After about 5 minutes, add the diced onion and continue cooking until the beef is fully browned and the onion is softened.
Season with salt, pepper, and any optional spices like garlic powder or paprika. Drain any excess fat from the pan.
Step 3: Combine with the Cream Sauce
Stir the cream of mushroom soup and sour cream into the beef mixture. Let it cook for 2–3 minutes, stirring often, until everything is heated through and well combined.
Step 4: Assemble the Casserole
Spread the beef mixture evenly into the prepared casserole dish.
Sprinkle 1 cup of shredded cheddar cheese over the beef mixture.
Arrange the tater tots in a single layer over the cheese, covering the entire surface.
Step 5: Bake
Bake the casserole for 25–30 minutes, or until the tater tots are golden brown and crispy.
Step 6: Add Final Cheese Layer
Remove the casserole from the oven. Sprinkle the remaining 1 cup of cheddar cheese over the top.
Return to the oven for another 5 minutes, or until the cheese is melted and bubbly.
Step 7: Serve
Let the casserole rest for 5 minutes before serving. This helps it set up and makes it easier to slice. Enjoy!
Tips for Success
- Don’t skip draining the fat — this keeps the casserole from becoming greasy.
- Use sharp cheddar for extra flavor.
- Add vegetables to make it a one-dish meal — frozen corn, peas, or green beans work great.
- Make it spicy by adding a sprinkle of cayenne or a dash of hot sauce to the beef mixture.

Storage and Make-Ahead Tips
- Refrigerate: Store leftovers covered in the fridge for up to 3 days.

- Reheat: Warm in the oven at 350°F until heated through, or microwave individual portions.
