Ingredients

1 bag 32 ounces frozen tater tots
1 lb. ground beef
1 medium yellow onion finely chopped
2 cloves garlic minced
3 tablespoons taco seasoning
1 (15 ounce) can black beans rinsed and drained
1 (15 ounce) can can whole kernel corn drained
1 (14.5 ounce) can fire roasted tomatoes
1 (7 ounce) can green chiles
2 cups shredded cheddar cheese divided
½ cup sour cream warmed to room temperature for 40 minutes
kosher salt to taste
freshly ground black pepper to taste

Instructions

Preheat oven to 425
Spread the tater tots over a large baking sheet. Bake the tater tots in the preheated oven for 15 minutes.
Brown the ground beef in a large ovenproof skillet over medium heat. About halfway through the browning process, add the chopped onions. Continue cooking until the ground beef is browned and the onions are soft. Drain any excess grease. Reduce the heat to low and add the garlic. Cook for 1 minute while stirring constantly.
Reduce oven temperature to 375 degrees.
Add the taco seasoning, black beans, corn, fire-roasted tomatoes, and diced green chiles to the hamburger mixture. Simmer over low heat for 5 minutes. Remove the pan from the heat and cool for 10 minutes. Stir in 1 cup shredded cheddar and the sour cream. If you are not cooking this in an ovenproof skillet at this time, transfer the contents to a 9x13-inch casserole dish.
Layer the tater tots on the top of the hamburger mixture in the skillet. Bake uncovered for 15 minutes. Remove the skillet from the oven and top with the remaining cheese. Bake for 12-15 more minutes or until the cheese is melted.

Notes

Store leftovers in an airtight container in the refrigerator for up to 3 days or freeze in a sturdy freezer container for up to 2 months. Thaw in the fridge overnight.
Reheat in the oven at 375 degrees for about 20-25 minutes or until warm. Or in the microwave at 70% power for 3-4 minutes or until warmed.
