Start by preheating your oven to 400°F (200°C). Heat the olive oil in a large skillet over medium heat. Add the diced onions and bell pepper. Cook them for about 5 to 6 minutes, or until they soften and start smelling sweet and savory.
Next, add the ground beef directly into the pan with the vegetables. Use a spoon to break it up as it cooks. Let it brown for 6 to 8 minutes. Once it’s no longer pink, stir in the garlic, taco seasoning, and smoked paprika. Let everything cook for 1 more minute so the spices can release their flavors.
Add the pickled jalapeños, corn, black beans, and enchilada sauce. Stir well so everything is evenly coated. Simmer the mixture for 2–3 minutes. Season with salt and pepper as needed.
Turn off the heat. Stir in the sour cream and 1 cup of shredded cheese. This makes the beef mixture creamy and cheesy—just the way we want it.
Transfer the beef mixture to your baking dish. Spread it out into an even layer. Then, take your frozen tater tots and neatly arrange them on top in a single layer.
Pop the dish into the oven and bake for 25 minutes. After that, take it out and sprinkle the remaining 1 cup of cheese over the tots. Return it to the oven for 10 more minutes. The cheese should be bubbly, and the tots golden and crisp. Let it rest for 5 minutes before serving—it’s going to be hot!
