Set your oven to 400°F (200°C) and coat a casserole dish (9×13 inches) with some cooking spray or a little oil.
02 -
Cook the ground beef with the chopped onion in a skillet over medium heat. Stir occasionally until the meat isn't pink, around 5-7 minutes. Drain off the grease.
03 -
Add your pizza or marinara sauce, the Italian seasoning, and some salt and pepper to the skillet with the beef. Stir it up nicely and let it cook for a few minutes.
04 -
Spread the beef-sauce mixture evenly across the greased dish. On top, scatter 1 cup of shredded cheese across the meat.
05 -
Line the tater tots in a single row over the cheesy meat layer. Toss the other cup of cheese across the tots evenly.
06 -
Put your dish into the oven and bake it for about 25-30 minutes. You'll know it's ready when the tater tots are crispy and golden, and the cheese is bubbling.
07 -
If you'd like, throw on your favorite toppings like olives, peppers, or mini pepperoni. Let it warm up in the oven for another 5 minutes.
08 -
Take it out of the oven and wait a few minutes before digging in. It's casserole time!
