This hearty Pizza Tot Casserole combines two beloved comfort foods into one irresistible dish that has become my go-to solution for busy weeknights when I need something guaranteed to please everyone at the table.
I created this recipe during a particularly chaotic week when both pizza night and tater tot night were requested by different family members. The compromise became an instant hit, and now it appears on our monthly rotation as the most requested comfort food mashup.
Ingredients
- Ground beef: Provides the hearty base and pairs perfectly with the pizza flavors
- Onion: Adds aromatic sweetness when cooked with the beef
- Marinara sauce: Infuses the dish with classic pizza flavor without extra work
- Italian seasoning: Creates authentic pizza taste with just one ingredient
- Mozzarella cheese: Creates that iconic stretchy pizza cheese pull
- Frozen tater tots: Deliver the perfect crispy contrast to the saucy base
- Optional toppings: Like pepperoni and olives make each casserole unique
Step-by-Step Instructions
- Preheat Oven:
- Set your oven to 400°F and thoroughly grease a 9×13 baking dish. This temperature ensures your tater tots get properly crispy while the cheese achieves that perfect golden bubble. I prefer using a ceramic baking dish as it conducts heat evenly and looks nice for serving.
- Cook the Beef:
- Brown ground beef and diced onion in a large skillet over medium heat for 5-7 minutes. Break the meat into small crumbles as it cooks for the best texture. Be sure to drain any excess grease after cooking this prevents the final casserole from becoming soggy or oily.
- Season and Sauce:
- Add marinara sauce Italian seasoning salt and pepper to your beef mixture. Allow everything to simmer for 2-3 minutes which concentrates the flavors and allows the beef to absorb the seasonings. I sometimes add a pinch of red pepper flakes here for adults who enjoy a slight kick.
- Assemble the Casserole:
- Spread your seasoned beef mixture evenly across the bottom of your greased baking dish. Top with half the cheese which serves as a binding layer. I find using a rubber spatula helps create a perfectly even layer.
- Add Tater Tots:
- Arrange frozen tater tots in a single layer covering the entire surface. This is where the magic happens the tots will crisp up while absorbing flavors from below. For extra crispiness do not overcrowd your tots give them a little breathing room.
- Bake:
- Place your assembled casserole in the oven for 25-30 minutes until the tater tots turn golden brown and crispy. The key here is patience allowing enough time for the tots to properly crisp while the cheese beneath melts into bubbly perfection.

The Italian seasoning is my secret weapon in this recipe. I discovered that using a quality blend makes all the difference in bringing that authentic pizza parlor flavor to the dish. My children now request this casserole for special occasions, calling it "pizza but better" which is high praise coming from pizza purists.
Make It Your Own
This casserole is incredibly versatile. Try using ground turkey or plant-based crumbles instead of beef for a lighter option. The key is to ensure whatever protein you choose is well-seasoned. My vegetarian sister loves it with Beyond Meat crumbles and says it satisfies her pizza cravings perfectly.

For a spicier version, add diced jalapeños or a few dashes of hot sauce to the beef mixture. My husband particularly enjoys when I add pepperoncini peppers to half the casserole for an adult-friendly kick that reminds him of his favorite pizzeria.
Storage Tips
This casserole keeps beautifully in the refrigerator for up to three days. Store in an airtight container and reheat individual portions in the microwave for 1-2 minutes. For best results when reheating a larger portion, use the oven at 350°F for about 15 minutes to maintain the crispy texture of the tater tots.
You can also freeze this casserole either before or after baking. When freezing unbaked, assemble everything except the tater tots, which should be added just before baking. Frozen casseroles will keep for up to three months when properly wrapped in freezer-safe containers.
Kid-Friendly Variations
My children love helping create this dish, especially when we turn it into a build-your-own adventure. I divide the casserole into sections before adding toppings, allowing each family member to customize their portion. This has become a Friday night tradition that everyone looks forward to.
For younger children who might be wary of combined foods, I sometimes serve this deconstructed with the tater tots, cheese and meat sauce in separate sections of their plate. This approach has helped introduce new flavors without overwhelming picky eaters.
