How to Make:

Quick Overview

This casserole is quick to assemble, satisfying in flavor, and perfect for busy evenings. It combines a simple browned ground beef base with corn and diced tomatoes, folded into a creamy mushroom sauce, topped with cheddar, and finished with a blanket of tater tots that bake until crisp. Preparation is straightforward and beginner-friendly. Expect about 15 minutes of active prep and 40 to 45 minutes of baking time for a total of roughly 60 minutes from start to finish. The standout element is the creamy sauce meeting the crunchy tater top.

Ingredients

1 1/2 pounds ground beef (85/15 lean), raw
1 cup corn kernels, drained if canned or thawed if frozen
1 (10 oz) can diced tomatoes, drained
2/3 cup condensed cream of mushroom soup, room temperature
1/3 cup whole milk, room temperature
1/4 cup sour cream, room temperature
1 cup shredded sharp cheddar cheese, divided, shredded
1 teaspoon onion powder
1/2 teaspoon black pepper
32 ounces frozen tater tots, straight from the freezer
1 tablespoon chopped fresh parsley, for garnish

Directions

Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch casserole dish with cooking spray or a thin layer of oil to prevent sticking.
In a large skillet over medium heat, add the ground beef. Break it up with a wooden spoon and cook until fully browned and no longer pink, about 7 to 8 minutes. Stir occasionally so it cooks evenly. Drain any excess fat by carefully tilting the pan and using a spoon or pour into a heat-proof container.
Return the skillet to medium heat and stir in the corn and the drained diced tomatoes. Cook for 1 to 2 minutes to warm through.
Add the condensed cream of mushroom soup, half of the shredded cheddar cheese (about 1/2 cup), whole milk, sour cream, onion powder, and black pepper. Stir continuously until the mixture becomes smooth, creamy, and evenly combined, about 2 to 3 minutes. Taste and adjust seasoning if needed.
Spread the beef mixture evenly into your prepared 9×13-inch baking dish, smoothing the top with a spatula so the surface is level.
Sprinkle the remaining cheddar cheese evenly across the top of the beef mixture. This creates a cheesy barrier before the tots go on.
Arrange the frozen tater tots in a single layer over the casserole, covering the surface so each bite gets a crispy top. No need to thaw — they bake crisp from frozen.
Bake uncovered in the preheated oven for 40 to 45 minutes, or until the tater tots are crispy and golden and the casserole is bubbling around the edges.
For an extra melty finish, sprinkle a little more shredded cheddar across the top after the initial bake and return to the oven for 5 minutes until melted.
Remove from the oven and let the casserole rest 5 minutes before serving. Sprinkle chopped fresh parsley for a bright touch.

What to Serve With

Pair this cowboy casserole with light, bright sides to balance the richness. A simple mixed green salad with a lemon vinaigrette, steamed green beans with a squeeze of lemon, or roasted broccoli are all great options. For a heartier meal, serve with warm dinner rolls or cornbread. Drinks that pair well include iced tea, a crisp lager, or a citrusy soda for kids. For a full family-style meal, add a bowl of coleslaw for crunch and a tangy counterpoint.

Top Tips for Perfecting

Ingredient substitutions: Swap ground beef for ground turkey or chicken for a leaner option, or use a plant-based crumble for a vegetarian twist. Use cream of chicken if you prefer a milder flavor.
Timing adjustments: If your tater tots brown too quickly, tent the dish loosely with foil for the first 25 minutes, removing foil for the final bake to crisp.
Flavor enhancements: Add a teaspoon of smoked paprika or a splash of Worcestershire sauce to the beef mixture for deeper flavor. Stir in a cup of cooked, drained black beans for extra protein and fiber.
Common mistakes to avoid: Don’t overcrowd the skillet when browning beef — cook in batches if needed. Drain excess fat to prevent a greasy casserole. Ensure the tater tots are in a single layer for even crisping.
Finish with freshness: A squeeze of lemon or a sprinkle of fresh parsley brightens the dish and balances the creaminess.

Storing and Reheating Tips

Store leftover casserole in an airtight container or cover the baking dish tightly with foil or plastic wrap. Refrigerate for up to 3 to 4 days. To freeze, place cooled casserole portions in freezer-safe containers for up to 2 months; thaw overnight in the refrigerator before reheating.

Reheat in the oven at 350°F (175°C) for 20 to 25 minutes covered with foil, then remove the foil and bake 5 to 10 minutes more to re-crisp the tater tots. For single servings, microwave on medium power for 2 to 3 minutes, then crisp under a broiler or in a toaster oven for a minute if desired.

FAQs

Can I make this casserole ahead of time?
Yes. Assemble the casserole, cover tightly, and refrigerate for up to 24 hours before baking. Add a few extra minutes to the baking time if going from chilled.

Can I use fresh corn instead of canned or frozen?
Absolutely. Use about 1 cup of fresh corn kernels, cooked briefly or blanched, for the best texture.

Is there a way to make this gluten-free?
Yes. Ensure the condensed soup you use is labeled gluten-free or make a quick homemade roux with gluten-free flour. Most other ingredients are naturally gluten-free.

How do I make the topping extra crispy?
Place the casserole on the top rack of the oven for the last 10 minutes of baking and broil for a minute or two, watching carefully to avoid burning.

Can I add vegetables to make it healthier?
Definitely. Stir in cooked diced bell peppers, mushrooms, or spinach to boost nutrition. Just saute any extra vegetables first to avoid adding moisture.
