In a large skillet over medium heat, cook the ground beef and diced onion until the beef is browned and the onion is soft, about 5-7 minutes. Drain any excess grease.

Add the marinara or pizza sauce, Italian seasoning, and a pinch of salt and pepper to the skillet. Stir to combine and let it simmer for a couple of minutes.

Spread the beef and sauce mixture evenly in the prepared baking dish. Sprinkle 1 cup of the shredded cheese over the beef mixture.

Arrange the tater tots in a single layer over the cheese and beef mixture. Sprinkle the remaining 1 cup of cheese on top of the tater tots.

Place the casserole in the preheated oven and bake for 25-30 minutes, until the tater tots are golden and crispy, and the cheese is melted and bubbly.

If desired, add mini pepperoni, olives, bell peppers, or any other pizza toppings over the casserole. Bake for an additional 5 minutes until toppings are heated through.
