Cowboy Casserole
This hearty cowboy casserole is a Tex-Mex twist on the classic Midwestern hot dish. It combines savory taco-seasoned ground beef with a creamy, rich filling loaded with corn and black beans, all topped with gooey cheddar cheese and perfectly golden, crispy tater tots for the ultimate comfort food experience.
Equipment
- Large Oven-Safe Skillet or Cast Iron Skillet - 12-inch recommended
- 9x13-inch baking dish - Use if not using an oven-safe skillet
- Cutting board
- Sharp knife
- Wooden spoon or silicone spatula
- Measuring cups and spoons
- Box grater - Highly recommended for shredding your own cheese
- Aluminum foil - Optional, for covering leftovers
Ingredients
- 1½ lbs ground beef - 680g, 80/20 lean-to-fat ratio
- 1 medium yellow onion - diced
- 3 cloves garlic - minced
- 1 packet taco seasoning - 1 oz / 28g
- 1 tablespoon Worcestershire sauce
- 1 can condensed cream of mushroom soup - 10.5 oz / 298g, undiluted
- ½ cup sour cream - 120ml
- 1 can black beans - 15 oz / 425g, drained and rinsed
- 1 can whole kernel corn - 15 oz / 425g, drained
- 1½ cups sharp cheddar cheese - 170g, shredded, divided
- salt and black pepper - to taste
- 1 bag frozen tater tots - 32 oz / 907g
- cooking spray - for greasing the baking dish
Instructions
- Preheat your oven to 375°F (190°C) and lightly grease a 9x13-inch baking dish with cooking spray. Set your frozen tater tots aside on the counter.
- Heat a large skillet over medium-high heat. Add the ground beef and cook, breaking it apart with a wooden spoon, for 7-8 minutes until browned and no pink remains. Drain off the excess fat.
- Reduce heat to medium. Add the diced onion to the skillet and cook for 4-5 minutes until softened and translucent. Add the minced garlic and cook for 1 more minute until fragrant.
- Stir in the taco seasoning packet and Worcestershire sauce, cooking for 1 minute to allow the spices to bloom. Season with salt and pepper to taste.
- Reduce heat to low. Add the undiluted cream of mushroom soup and sour cream, stirring until fully incorporated and smooth. Mix in the drained black beans, corn, and ¾ cup (85g) of the shredded cheddar cheese until melted into the filling.
- Transfer the filling mixture into the prepared 9x13-inch baking dish (if not using an oven-safe skillet) and spread it into an even layer.
- Sprinkle the remaining ¾ cup (85g) of shredded cheddar cheese evenly over the filling. Arrange the frozen tater tots in a single, snug layer on top of the cheese.
- Bake, uncovered, on the center rack for 35-40 minutes until the tater tots are deep golden brown and crispy and the filling is bubbly. For extra-crispy tots, broil for 2-3 minutes at the end.
- Remove from the oven and let the casserole rest for 5 minutes before serving. This allows the filling to set slightly for cleaner serving portions.
Notes
- Make it Ahead: Assemble the casserole completely (without the tater tots) and refrigerate for up to 24 hours. Add the frozen tater tots just before baking, and add 5 extra minutes to the bake time.
- Drain the Fat: Don't skip draining the excess grease from the ground beef, as it will make the filling greasy and prevent the sauce from being creamy.
- Use Freshly Shredded Cheese: Pre-shredded cheese contains anti-caking agents that prevent smooth melting. Grating your own cheddar yields a much silkier, gooier result.
- Pack the Tater Tots Tightly: The tots shrink as they bake, so pack them snugly side by side for maximum coverage and crunch.
- Soup Substitutes: Cream of chicken, cream of celery, or cream of potato soup are excellent substitutes for cream of mushroom. Use them undiluted, straight from the can.
- Freezing Instructions: You can freeze the unbaked casserole (without the tater tots) for up to 3 months. Thaw overnight in the refrigerator, add the frozen tater tots, and bake as directed.
- Spicy Variation: For extra heat, add a can of diced green chiles, a teaspoon of cumin, or a drizzle of hot sauce to the filling. Top with sliced pickled jalapeños before baking.
- Lighter Version: Swap the ground beef for lean ground turkey, and use low-sodium soup and beans to reduce the salt content.
- Resting is Key: Letting the casserole rest for 5 minutes after baking helps the filling firm up, so you get clean, scoopable servings instead of a soupy mess.
- Fresh Toppings: Elevate the dish by adding fresh toppings at the table, such as sour cream, salsa, sliced green onions, jalapeños, or fresh cilantro.
