Cowboy Casserole Recipe Ingredients

• 1 tablespoon vegetable oil
• 1½ pounds lean ground beef
• 1 small yellow onion, diced
• 2 garlic cloves, minced
• 1 teaspoon chili powder
• 1 teaspoon smoked paprika
• ½ teaspoon ground cumin
• ½ teaspoon salt
• ¼ teaspoon ground black pepper
• 1 can (10 ounces) diced tomatoes with green chiles, undrained
• 1 can (15 ounces) whole-kernel corn, drained
• 1 can (10½ ounces) condensed cream of mushroom soup

• 1 tablespoon chopped fresh parsley or sliced green onions, optional

How to Make Cowboy Casserole

1. Heat the oven and prepare the dish.
   Preheat the oven to 375°F. Lightly grease a 9-by-13-inch baking dish with cooking spray or a small amount of oil.
2. Brown the ground beef.
   Heat the vegetable oil in a large skillet over medium-high heat. Add the ground beef and diced onion.Cook for 6 to 8 minutes, breaking the beef into small crumbles with a wooden spoon. Continue cooking until the meat is browned and the onion is soft. Drain away any excess grease.
3. Add the garlic and seasonings.
   Return the skillet to medium heat. Stir in the garlic, chili powder, smoked paprika, cumin, salt, and black pepper.Cook for about 30 seconds. The garlic and spices should smell warm and fragrant, but do not let the garlic burn.
4. Make the creamy beef filling.
   Add the diced tomatoes with their liquid and the drained corn. Stir in the condensed soup and sour cream until the mixture is evenly combined.Let the filling cook for 2 to 3 minutes, stirring occasionally. It should be creamy and thick enough to hold together, not watery.
5. Add the first layer of cheese.
   Remove the skillet from the heat. Stir in 1 cup of the shredded cheddar cheese until it begins to melt into the warm filling.
6. Fill the baking dish.
   Spoon the beef mixture into the prepared baking dish. Spread it into an even layer, making sure the corners are filled.
7. Arrange the tater tots.
   Place the frozen tater tots over the beef mixture in a single layer. You can line them up neatly or scatter them across the top, but avoid piling them on one another so they can brown evenly.
8. Bake the casserole.
   Bake uncovered for 30 minutes. The filling should be bubbling around the edges, and the tater tots should be starting to turn crisp and golden.
9. Add the remaining cheese.
   Sprinkle the remaining 1 cup of cheddar over the tater tots. Return the casserole to the oven and bake for another 8 to 10 minutes, until the cheese is fully melted.For a crisper top, broil the casserole for 1 to 2 minutes at the end. Watch it closely because the cheese can brown quickly.
10. Rest and serve.
    Let the casserole rest for 5 to 10 minutes before serving. This short rest helps the creamy filling thicken, making each portion easier to scoop.Sprinkle with parsley or green onions, if desired.

Recipe Notes and Helpful Tips

Drain the beef well

Too much grease can make the filling oily and prevent it from thickening properly. After browning the beef, carefully drain off the excess fat before adding the remaining ingredients.

Keep the tater tots frozen

There is no need to thaw them. Frozen tater tots hold their shape better and become crisp as the casserole bakes.

Adjust the heat

Diced tomatoes with green chiles add mild warmth. For a gentler version, use plain diced tomatoes. For more heat, add sliced jalapeños or a pinch of cayenne pepper.

Try different vegetables

Drained black beans, pinto beans, peas, or chopped bell peppers can be added to the filling. Keep the total amount of extra ingredients to about 1 or 2 cups so the casserole does not overflow.

Make it ahead

Prepare the beef filling and spread it in the baking dish up to 24 hours in advance. Cover and refrigerate it without the tater tots.

When ready to bake, add the frozen tater tots and allow a few extra minutes in the oven because the filling will be cold.

Storing leftovers

Cover the casserole tightly or transfer leftovers to an airtight container. Refrigerate for up to four days.

Reheat individual servings in the microwave, or warm a larger portion in a 350°F oven until heated through. The oven gives the tater tots a better chance of becoming crisp again.

Frequently Asked Questions

What is Cowboy Casserole made of?

Cowboy Casserole is usually made with seasoned ground beef, corn, a creamy sauce, shredded cheese, and frozen tater tots. Some versions also include beans, tomatoes, bell peppers, or green chiles.

Can I use ground turkey instead of ground beef?

Yes. Ground turkey works well in this easy Cowboy Casserole. Because turkey is leaner, cook it with an extra teaspoon of oil and season it generously so the filling stays moist and flavorful.

Why are my tater tots soggy?

Tater tots may become soggy if the filling contains too much liquid or if they are packed too closely together. Drain the beef and corn well, use undiluted condensed soup, and arrange the tots in a single layer.

Can Cowboy Casserole be frozen?

Yes. Assemble the beef filling in a freezer-safe baking dish, but wait to add the tater tots and final cheese layer. Cover and freeze for up to three months.

Thaw overnight in the refrigerator, add the frozen tater tots, and bake as directed. Add extra baking time as needed until the center is hot.

A Cozy Dinner for Hungry Evenings

This casserole is not delicate, and that is part of its charm. It is cheesy, hearty, crisp around the edges, and generous enough to feed a hungry table. Serve it with a simple green salad or steamed vegetables, then save any leftovers for an easy lunch the next day.
