Ingredients
For the Filling:
1.5 lbs (680g) lean ground beef (85/15 or 90/10)
1 medium yellow onion, diced
1 medium green bell pepper, diced
3 cloves garlic, minced
1 (15 oz) can sweet corn, drained
1 (15 oz) can pinto beans or kidney beans, drained and rinsed
1 (10.5 oz) can condensed cream of mushroom soup (or cream of celery)
1 cup sour cream
1 (10 oz) can diced tomatoes with green chilies (like Rotel), drained
2 tablespoons tomato paste
1 tablespoon Worcestershire sauce
1 teaspoon smoked paprika
1 teaspoon chili powder
½ teaspoon ground cumin
Salt and freshly ground black pepper, to taste
1 tablespoon olive oil
For the Topping:
1 (32 oz) bag frozen tater tots
2 cups shredded sharp cheddar cheese, divided
¼ cup thinly sliced green onions or chopped fresh parsley (for garnish)
Optional for serving: extra sour cream, pickled jalapeños, hot sauce
Equipment
Large, oven-safe skillet (12-inch cast iron is ideal) OR a 9×13 inch baking dish
Wooden spoon or spatula
Mixing bowl
Oven preheated to 375°F (190°C)
Instructions
Step 1: Brown the Beef & Veggies
Preheat your oven to 375°F (190°C). Heat the olive oil in your large oven-safe skillet over medium-high heat. Add the diced onion and bell pepper, sautéing for 4-5 minutes until softened. Add the ground beef, breaking it up with your spoon, and cook until no longer pink, about 6-7 minutes. In the last minute, add the minced garlic and cook until fragrant. Carefully drain any excess grease from the skillet.
Step 2: Build the Savory Filling
Reduce the heat to medium. To the beef mixture, stir in the drained corn, beans, drained diced tomatoes, and tomato paste. In a separate bowl, whisk together the cream of mushroom soup, sour cream, Worcestershire sauce, smoked paprika, chili powder, and cumin. Pour this creamy mixture into the skillet and stir until everything is beautifully combined and heated through. Season generously with salt and pepper. Taste and adjust seasoning—this is your flavor base! Remove from heat.
Step 3: Layer & Bake to Perfection
If using a baking dish, transfer the beef mixture into it now, spreading it into an even layer. Sprinkle 1 cup of the shredded cheddar cheese evenly over the hot filling. This creates a deliciously gooey middle layer. Now, artfully arrange the frozen tater tots in a single, snug layer over the entire surface. They are your crispy, potatoey roof!
Step 4: The Final Bake
Place the skillet or dish on the center rack of your preheated oven. Bake for 25 minutes. Carefully remove it (the handle will be hot!) and evenly sprinkle the remaining 1 cup of cheddar cheese over the tater tots. Return to the oven for 8-12 more minutes, or until the cheese is completely melted and bubbly, and the tater tots are deep golden brown and crispy.
Step 5: Rest & Serve
This is a crucial step for setting the casserole! Let it rest for 8-10 minutes after removing it from the oven. This allows the filling to thicken slightly, making serving much cleaner. Garnish with sliced green onions or fresh parsley. Serve directly from the skillet at the table for a rustic, communal feel, scooping out hearty portions onto plates.
Chef’s Notes & Variations
Make it Spicy: Use hot diced tomatoes with green chilies, add a diced jalapeño with the onions, or mix ½ teaspoon of cayenne pepper into the filling.
Protein Swap: Ground turkey, chicken, or even plant-based crumbles work wonderfully.
Vegetable Boost: Stir in a handful of spinach or diced zucchini with the corn and beans.
Texture Tip: For extra crispy tots, you can bake them on a sheet pan for 10 minutes before adding them to the casserole.
Make Ahead: Assemble the casserole completely (through Step 3), cover tightly, and refrigerate for up to 24 hours. Add 5-10 minutes to the bake time when cooking from cold.
Storage & Reheating: Store leftovers in an airtight container in the refrigerator for up to 4 days. Reheat individual portions in the air fryer or toaster oven to keep the tots crispy, or in the microwave for 2-3 minutes until hot.
