Pizza Tot Casserole brings together two of my all time favorite comfort foods into one cozy bake that hits all the right notes for weeknight dinners and weekend gatherings. It is cheesy like lasagna but loaded with the fun crunch of crispy tots on top. When my family craves something hearty that satisfies both pizza and casserole lovers, this is my go to recipe. It delivers that classic pizza flavor but comes together with pantry basics and almost no fuss.
I first made this when the kids could not decide between pizza and tater tots and it has been a regular request ever since. The blend of gooey cheese and pizza sauce is so nostalgic and I can count on everyone cleaning their plate.
Ingredients
- Ground beef: Using beef gives a meaty flavor and heartiness but you can also swap for Italian sausage for extra punch. Select beef with a bit of fat for better taste.
- Onion: Adds depth and natural sweetness. Choose a firm small onion with no soft spots.
- Marinara or pizza sauce: These sauces bring the signature pizza flavor. Go for a thicker marinara for less watery casserole.
- Italian seasoning: Boosts the unmistakable herby pizza aroma. Use a blend that smells fresh and intense.
- Salt and pepper: Balances out all the flavors. Taste your sauce and beef before baking so it is just right.
- Shredded mozzarella cheese: Melts beautifully for that ooey gooey factor. A mix of mozzarella and cheddar gives stretch and tang.
- Frozen tater tots: Fun crispy topping that turns golden in the oven. Look for a brand with a simple ingredient list and no broken pieces.
- Mini pepperoni slices: These are optional but add that classic pizza bite
- Sliced black olives: Provide briny flavor and easy color contrast
- Bell pepper: Fresh crunch and color works well get one with bright skin
- Green onions: Lively garnish for a bit of zip
- Mushrooms: Earthy flavor and extra heartiness avoid soggy varieties
Step-by-Step Instructions
- Preheat the Oven:
- Get your oven up to a hot 400 degrees Fahrenheit which ensures both the cheesy layer and tots crisp up evenly. Grease your baking dish with a light brushing of oil so nothing sticks and clean up stays easy.
- Cook the Beef and Onion:
- Place a large skillet over medium heat and add your ground beef and diced onion together. Let them cook gently for about seven minutes. Use a spatula to break up the meat so there are no big chunks. The onion should soften and turn nearly translucent and the beef will get browned bits for added flavor. Drain off any grease so your casserole is not oily.
- Season and Add the Sauce:
- Sprinkle in your Italian seasoning then pour over the marinara or pizza sauce. Give the mix a careful stir so the beef gets coated in all those herby and tomato rich flavors. Add salt and pepper to bring it all together. Allow the whole skillet to simmer quietly for two or three minutes while the sauce thickens slightly.
- Assemble the Casserole:
- Spoon the beef and sauce mixture into your prepared baking dish, smoothing it into a nice even layer so every bite is balanced. Scatter one cup of the shredded cheese directly onto this hot mixture. The heat will help the cheese start to melt and blend right in.
- Top with Tater Tots and Cheese:
- Take your bag of frozen tots and gently arrange them all across the casserole in one tidy layer. Make sure they cover almost all the surface so you get maximum crunch. Then sprinkle your last cup of cheese over the tots so they bake up melty and golden at the same time.
- Bake to Golden Perfection:
- Slide the casserole into the preheated oven and let it bake for about twenty five to thirty minutes. You are looking for bubbling cheese, crunchy tater tots, and the sides to look just barely caramelized. Everything should smell irresistible at this point.
- Add Optional Toppings:
- If you love that loaded pizza shop vibe, this is your chance. Layer on mini pepperoni, olives, bell pepper, or mushrooms right over the top. Return the baking dish to the oven for just five minutes so these extra toppings are piping hot and the cheese gets extra gooey.
- Cool and Serve:
- Carefully take the dish out of the oven and let it cool for at least five minutes. This helps everything set up so you get cleaner slices. The cheese and filling will still be hot and melty so serve up and enjoy.

The mozzarella in this recipe truly makes every bite stretchy and irresistible I always smile when I see my kids trying to stretch the cheese as high as they can from pan to plate It feels like the perfect mix of tradition and fun with every serving
Storage Tips
Let leftovers cool then scoop into an airtight container and refrigerate for up to three days The casserole holds up well and can be reheated in the microwave right in your lunch container or in the oven for best texture If freezing cover tightly with foil and use within two months The tots will not be quite as crisp but the flavors all meld deliciously
Ingredient Substitutions
Italian sausage is a flavorful swap for ground beef Any type of shredded cheese will work but mozzarella gives the true pizza effect You can use any hearty tomato based red sauce you have on hand and for a leaner dish use ground turkey Tots can be replaced with crispy hash brown rounds if you want a change
