This pizza tater tot casserole combines two family favorites into one irresistible dish. The savory ground beef mixture topped with crispy tater tots and melty cheese creates a comfort food masterpiece that satisfies pizza cravings in casserole form.
I created this recipe when my pantry was nearly empty but the kids were clamoring for both pizza and tater tots. What started as a desperate dinner solution has become our most requested meal for movie nights.
Ingredients
- Ground beef: Provides the hearty base just like a meat lovers pizza
- Green pepper: Adds a fresh vegetable element and authentic pizza flavor
- Onion: Creates depth of flavor as it caramelizes with the beef
- Fresh mushrooms: Contribute an earthy umami taste that elevates the dish
- Pizza sauce: Brings that classic tangy tomato flavor everyone loves
- Dried basil: Infuses an Italian herb profile throughout the casserole
- Mozzarella cheese: Creates that pizza pull factor we all crave
- Frozen Tater Tots: Make a crispy golden topping that beats traditional crust
- Cheddar cheese: Adds a sharp finishing touch and beautiful color
Step-by-Step Instructions
- Brown the Meat Mixture:
- Cook ground beef in a large skillet over medium heat until it begins to brown. Add chopped green pepper, onion, and mushrooms to the beef. Continue cooking until beef is completely browned and vegetables have softened. This takes about 8 to 10 minutes. Drain any excess grease from the pan to keep your casserole from becoming greasy.
- Season the Base:
- Add pizza sauce and dried basil to the meat mixture, stirring thoroughly to combine. Let it simmer for 2 to 3 minutes so the flavors meld together. The mixture should be saucy but not watery.
- Assemble the Casserole:
- Transfer the meat mixture to a greased 3 quart baking dish or 13x9 inch pan, spreading it evenly across the bottom. Sprinkle the mozzarella cheese evenly over the meat layer, using all 3 cups for maximum cheesy goodness. Arrange the frozen tater tots in neat rows covering the entire cheese layer.
- Bake to Perfection:
- Place the assembled casserole in a preheated 400°F oven and bake uncovered for 30 to 35 minutes. The tater tots should become golden brown and crispy on top. The casserole will be bubbling around the edges when ready.
- Add the Finishing Touch:
- Remove the casserole from the oven and sprinkle cheddar cheese evenly over the hot tater tots. Return to the oven for about 5 minutes until the cheddar melts completely and begins to bubble slightly. Let stand for 5 minutes before serving to allow the casserole to set.

The first time I served this casserole, my son declared it better than regular pizza. Now whenever we have guests over, they always ask if I'm making "that pizza tater tot thing." The combination of crispy potatoes and pizza flavors just works magic on everyone who tries it.
Make It Your Own
This casserole welcomes customization just like a pizza. Add pepperoni between the meat and cheese layers for a pepperoni pizza version. Italian sausage can replace some or all of the ground beef for a spicier profile. Vegetarians can substitute plant based ground for the beef or double up on vegetables like bell peppers, olives, and additional mushrooms.
Storage and Reheating
Store leftover casserole covered in the refrigerator for up to 3 days. For best reheating results, use an oven preheated to 350°F for about 15 minutes to restore the tater tot crispiness. Microwave reheating works in a pinch but sacrifices the crispy texture of the tots. This casserole also freezes beautifully either before or after baking. Wrap tightly and freeze for up to 3 months.
Serving Suggestions
Pair this hearty casserole with a simple green salad dressed with Italian vinaigrette to balance the richness. For a complete pizza night experience, serve with garlic bread sticks and a side of warm marinara sauce for dipping. Set up a toppings bar with sliced black olives, banana peppers, and crushed red pepper flakes so everyone can garnish their portion to taste.

This is sure to become a family favorite with its customizable pizza flavors and crispy tater tot topping. Enjoy!
