What is Cowboy Casserole?

Cowboy Casserole is a comforting, all-in-one baked dish made with ground beef, shredded cheese, corn, sour cream, and crispy tater tots. It’s similar to a classic tater tot hotdish, but with a Tex-Mex twist thanks to the Rotel tomatoes. The result is a creamy, cheesy, one-pan dinner with just the right amount of kick.

Cowboy Casserole ingredients.

Recipe Variations and Substitutions

  • Protein: Ground turkey or chicken works great in place of beef. Or skip the meat and use a mix of black beans and pinto beans for a protein-packed, vegetarian-friendly version
  • Cheese: Use what you have—cheddar, provolone, or pepper jack add great flavor
  • Tomatoes: Swap Rotel with regular canned tomatoes if you want it milder
  • Vegetables: Add a handful of frozen peas or bell peppers to the meat mixture for extra veg
  • Spicy Version: Add a can of diced green chilies or a few chopped jalapeños to the meat mixture for extra heat and flavor
  • Cornbread Twist: For a fun variation, swap tater tots with cornbread batter to make a cowboy cornbread casserole.

How to Make Cowboy Casserole

  1. Prep the pan and tater tots: Preheat oven to 375°F. Spray a 9×13-inch casserole dish. Arrange tater tots in a single layer and bake for 8 minutes. Remove and set aside. Increase oven temperature to 425°F.
  2. Cook the beef mixture: In a large skillet, brown the ground beef and onion over medium heat until the beef is fully cooked and the onion is soft. Drain any excess grease.
  3. Add seasoning and simmer: Stir in Rotel tomatoes, garlic powder, onion powder, and black pepper. Cook for 8 minutes or until the liquid reduces.
  4. Combine filling: Remove from heat. Stir in sour cream, soup, corn, and ½ cup shredded cheese until the cheese melts and mixture is creamy.
  5. Assemble casserole: Spread the beef mixture evenly in the prepared baking dish. Sprinkle ½ cup cheese over the top, then layer the pre-baked tater tots.
  6. Top and bake: Sprinkle remaining ½ cup cheese and chopped chives on top. Cover with foil and bake for 20 minutes. Remove foil and bake until cheese is bubbly and golden.
  7. Serve: Let the casserole rest for a few minutes before serving. Enjoy!

Recipe Tip: How do I keep the tater tots crispy on top?

Pre-bake the tater tots before assembling the casserole. This step helps them stay crispy and golden brown, even after baking under the cheese.

Jenn’s Notes

  • Pay super close attention to the ingredients above whether or not you should drain or not drain any of the canned ingredients! If you accidentally do the opposite, it will change the overall consistency and end product of your casserole!
  • Pro-Tip: It is not absolutely necessary that you bake the tater tots before putting them in the casserole. As long as they are thawed out, they will cook in the oven regardless. However, I highly recommend if you have the time, adding this easy step because they will turn out so much better! They will be far crunchier and crispier.
