- 2 cups marinara sauce
- 1 tsp Italian seasoning
- Salt and pepper (to taste)
- 2 cups shredded mozzarella cheese
- 1 bag (32 oz) frozen tater tots
- Optional Toppings: pepperoni, olives, bell pepper, green onions, mushrooms
Chef notes:
- Use a good marinara = better depth.
- Fresh onion = sweeter base.
- Mozzarella shred melts best finely shredded.
(Also, if you like a bit more zip, toss in a pinch of red pepper flakes.)
For another easy dessert to finish the meal, I sometimes pair it with this banana pudding recipe.
How to Make It
- First, preheat your oven to 400°F (200°C). Check with an oven thermometer if you have one. Grease a 9×13-inch dish or line with parchment for easy serving.
- Next, heat a skillet over medium. Add the ground beef and diced onion. Stir and break up the beef; cook until browned and the onion softens, about 5–7 minutes. Listen for a steady sizzle.
- Then, drain excess grease. Use a slotted spoon to leave fat behind so the casserole won’t feel greasy.
- Now return beef to the skillet (or leave it in the pan) and add 2 cups marinara, 1 tsp Italian seasoning, and a pinch of salt and pepper. Stir and let the sauce simmer and thicken for 2–3 minutes. You’ll smell the herbs bloom.
- Spread the beef and sauce evenly in the prepared dish. Sprinkle 1 cup of mozzarella over the meat to make a melty base.
- Arrange tater tots in a single layer on top. Press lightly so they sit snug. Then sprinkle the remaining 1 cup cheese over the tots.
- Place the casserole in the oven and bake 25–30 minutes until tots are golden and edges crisp. Look for bubbling cheese and browned tot edges.
- If you want toppings, add pepperoni, olives, or sliced peppers for the last 5 minutes of baking so they heat through but don’t burn.
- Finally, remove from oven and let sit 5–10 minutes. The cheese settles and serving becomes neater. Serve warm.

Kitchen Tips (From My Kitchen)
- Time-saver: Brown meat while you dice the onion so you finish faster.
- Common mistake + fix: Don’t skip draining—too much grease makes the tots soggy. Drain well.
- Simple variation: Stir a teaspoon of smoked paprika into the sauce for a warm, smoky twist.
I also keep a short author note on practical tips on my author page.
Serving Ideas
- Weeknight family dinner with a crisp green salad and pickles.
- Casual game-day plate: let everyone add their own toppings.
- Easy brunch option with a side of scrambled eggs.
- Holiday potluck bring-along—slice like a casserole and serve warm.
Garnish with green onions or a drizzle of extra marinara.
Storing & Leftovers
- Fridge: Store covered for 3–4 days.
- Freezer: Freeze portions up to 2 months (freeze before baking for best texture).
- Reheat: Warm in a 350°F oven until bubbly, 15–20 minutes, to keep tots crisp.
Leftover idea: Turn slices into a hearty sandwich with greens and a smear of sauce.
