This casserole brings together the nostalgia of pizza night and the comforting ease of tater tot hotdish. I first whipped this up when the fridge was bare except for tater tots and odds and ends and now it is firmly in the monthly dinner rotation at our house.
Ingredients
- Ground beef: Choose lean beef for less grease and rich flavor. Freshly ground is always great if available
- Yellow onion: Adds savory depth to the beef and makes the whole house smell amazing. Look for firm onions with papery skins
- Marinara sauce: This brings the tangy pizza flavor. Homemade or a high-quality jarred sauce adds tons of personality
- Italian seasoning: Adds herby notes reminiscent of your favorite pizza parlor
- Salt and pepper: Essential for boosting all the other flavors
- Shredded mozzarella cheese: Melt-in-your-mouth gooey texture and classic pizza flavor. Buy a block to shred for best melting
- Frozen tater tots: The star of the topping. Crisp up beautifully for that satisfying crunch. Check for brands with minimum ingredients for best texture
- Optional toppings: Like mini pepperoni, olives, bell pepper, green onion, or mushrooms let you make this casserole your own. Opt for fresh vibrant toppings for extra flavor
Instructions
- Preheat the Oven:
- Set your oven to four hundred degrees Fahrenheit. Give your baking dish a good greasing to keep the casserole from sticking. If you want extra-easy cleanup line the dish with parchment paper
- Brown the Beef and Onions:
- In a large skillet over medium heat add ground beef and diced onions. Stir frequently and use a spoon to break the meat into small pieces. Cook gently until the beef is fully browned and the onions are soft which should take about five to seven minutes. Drain off any excess grease so your casserole is not too oily
- Combine with Sauce and Seasonings:
- Return the cooked beef and onions to the skillet if you have removed them. Add marinara sauce Italian seasoning and a good pinch of salt and pepper. Stir thoroughly and allow this mixture to gently simmer for several minutes so the flavors meld and the sauce thickens
- Layer the Casserole Base:
- Spread the beef and sauce mixture evenly in your greased baking dish. Sprinkle half of the mozzarella cheese over the top. This cheese layer will create gooey glue for the tater tots above
- Arrange Tater Tots and Cheese:
- Lay out the tater tots in a single layer over the cheesy beef filling. Try to cover as much of the meat as possible. Top this tater tot layer with the remaining cheese so the whole top gets nice and bubbly
- Bake the Casserole:
- Slide the dish into your preheated oven. Bake for twenty-five to thirty minutes until the tater tots are deeply golden and crisp and the cheese is melted and bubbly. Watch near the end to make sure nothing burns
- Top and Finish Baking:
- If you are adding extra pizza toppings like pepperoni or veggies sprinkle them evenly over the baked casserole and return it to the oven for about five minutes just until the toppings are heated through
- Cool and Serve:
- Let the casserole cool for several minutes after removing it from the oven. This resting period will make it easier to slice and serve while ensuring the cheese does not ooze everywhere

One of my favorite parts about this dish is the extra-melty cheese that bubbles up around every tater tot. My kids love building their own section of toppings so everyone gets their ideal slice. Watching the cheese get all browned and stretchy is the moment we all look forward to when it comes out of the oven.
Storage Tips
To store leftovers let the casserole cool to room temperature and then cover the baking dish tightly with foil or plastic wrap. Refrigerate for up to three days. For best reheating results use the oven to keep the tots crisp rather than the microwave.
Ingredient Substitutions
You can swap the ground beef for ground turkey or chicken for a lighter option. Vegetarian crumbles also work beautifully. Use any pizza cheese blend or a mixture of mozzarella and cheddar if that is what you have. For the sauce try any pizza or tomato-based pasta sauce you enjoy.
Serving Suggestions
This is truly a meal on its own but a crunchy green salad or garlic bread makes a great side. For fun movie-night vibes serve with a little ranch or extra warm marinara for dipping. If you are feeding kids let them add their favorite toppings right at the table.

Success Stories
Several readers have shared that this dish got raves even from picky eaters. One mom told me her kids now ask for Pizza Tot Casserole instead of takeout pizza. The leftovers are popular for work lunch and the pan is always scraped clean at potlucks.
Freezer Meal Conversion
To make this ahead assemble up to the baking step then wrap tightly with foil and freeze for up to two months. Bake directly from frozen at four hundred degrees for about forty-five minutes or until bubbling and crispy all the way through. It is a lifesaver when you need a low-effort dinner in a hurry.
