Creating Cheesy Pizza Tot Casserole is a hassle-free process. Just follow these steps:

1. Preheat Oven: Start by preheating your oven to 425°F (220°C).
2. Prepare Pan: Grease a 9×13 inch baking dish with cooking spray or a bit of olive oil.
3. Layer Tater Tots: Evenly spread the frozen tater tots in a single layer across the bottom of the prepared baking dish.
4. Add Pizza Sauce: Pour pizza sauce over the tater tots, making sure to cover them adequately.
5. Sprinkle Cheese: Generously sprinkle half of the shredded mozzarella cheese over the sauce.
6. Add Toppings: Distribute pepperoni slices and diced bell peppers evenly atop the cheese.
7. Season: Sprinkle garlic powder, Italian seasoning, salt, and pepper over the top. Adjust seasoning according to your taste.
8. Finish with Cheese: Top the entire casserole with the remaining shredded mozzarella cheese for a cheesy finish.
9. Bake: Place the baking dish in the preheated oven and bake for 30-35 minutes or until golden and bubbly.
10. Cool: Once fully cooked, remove from the oven and let cool for 5-10 minutes. This allows the cheese to set slightly, making it easier to serve.
11. Garnish: Optionally, sprinkle chopped parsley or basil for a fresh touch.

These steps will lead you to a wonderfully cheesy, savory casserole that will satisfy your cravings for both pizza and comfort food.
