Tater Tot Breakfast Casserole

Ingredients

(Tip: You'll find the full list of ingredients and measurements in the recipe card below.)

1 (32 oz) bag frozen tater tots
1 pound breakfast sausage
8 large eggs
1 cup milk
2 cups shredded cheddar cheese
½ cup shredded mozzarella cheese
½ cup bell pepper, diced
¼ cup green onions, sliced
1 teaspoon garlic powder
½ teaspoon onion powder
Salt and black pepper to taste
Nonstick cooking spray

Directions

I start by preheating the oven to 375°F (190°C) and lightly greasing a 9x13-inch baking dish with nonstick cooking spray.

I arrange the frozen tater tots in an even layer across the bottom of the prepared baking dish.

In a large skillet over medium heat, I cook the breakfast sausage until it’s browned and fully cooked, breaking it apart as it cooks. I drain the excess grease, then sprinkle the sausage evenly over the tater tots.

In a large mixing bowl, I whisk together the eggs, milk, garlic powder, onion powder, salt, and black pepper until everything is smooth and well combined. I stir in the diced bell pepper and half of the shredded cheddar cheese.

I pour the egg mixture evenly over the tater tots and sausage. Then I sprinkle the remaining cheddar cheese and the mozzarella cheese over the top.

I bake the casserole for 35 to 45 minutes, until the eggs are set in the center and the top is golden brown. Once it’s done, I remove it from the oven and let it cool for 5 to 10 minutes before garnishing with sliced green onions. I slice and serve it warm.

Servings and timing

I prepare this casserole in about 15 minutes. It bakes for around 40 minutes, bringing the total time to approximately 55 minutes.

This recipe makes 8 servings, and each serving contains about 420 calories. I find this is the perfect amount for a family breakfast or a small gathering.

Variations

I sometimes swap the breakfast sausage for cooked bacon or diced ham when I want a different flavor. If I prefer a little heat, I add chopped jalapeños or a pinch of red pepper flakes to the egg mixture.

For a veggie-packed version, I mix in sautéed mushrooms, spinach, or onions. I also like experimenting with different cheeses, such as pepper jack for spice or a Colby blend for extra creaminess.

Storage/Reheating

I store leftovers in an airtight container in the refrigerator for up to 4 days. When I want to reheat a slice, I microwave it for about 1–2 minutes until warmed through.

If I have more time, I reheat it in a 350°F oven for about 10–15 minutes to help the edges crisp up again. I can also freeze individual portions by wrapping them tightly and storing them in a freezer-safe container for up to 2 months. I thaw overnight in the refrigerator before reheating.

FAQs

Can I make this casserole ahead of time?

Yes, I often assemble everything the night before, cover it tightly, and refrigerate it. In the morning, I bake it as directed, adding a few extra minutes if it’s cold from the fridge.

Can I use fresh potatoes instead of frozen tater tots?

I can, but I would need to cook them first to ensure they’re tender. I prefer tater tots because they give me a crisp texture with less effort.

How do I know when the casserole is fully cooked?

I check the center with a knife or toothpick. If it comes out clean and the eggs are set without jiggling, it’s ready.

Can I make this recipe without sausage?

Absolutely. I simply leave out the sausage or replace it with plant-based sausage or extra vegetables for a meatless option.

Can I double the recipe?

Yes, I double the ingredients and bake it in two 9x13-inch dishes. I make sure not to overcrowd one pan so it cooks evenly.

Conclusion

I find this Tater Tot Breakfast Casserole to be one of the easiest and most satisfying breakfast dishes I can make. It’s hearty, cheesy, and endlessly customizable. Whether I’m hosting brunch or just feeding my family on a weekend morning, this casserole always delivers comfort and flavor in every bite.
