Ingredients for Tater Tot Sausage Breakfast Casserole

This is a really hearty breakfast casserole. It's kind of old-fashioned and reminds me of something my mom and her friends used to make for brunch. The ingredients are simple, affordable, and probably already in your kitchen.

What You'll Need

• 1 pound breakfast sausage (pork sausage, crumbled)
• 1 small onion, diced
• 1 bell pepper, diced (any color)
• 8 large eggs
• 1 cup whole milk
• ½ teaspoon garlic powder
• ½ teaspoon onion powder
• ½ teaspoon salt
• ¼ teaspoon black pepper
• 2 cups shredded cheddar cheese (divided)
• 1 bag (32 ounces) frozen tater tots
• Optional: 2 tablespoons salsa or hot sauce (for extra flavor)

Why These Ingredients Matter

Tater tots create the signature texture. The crispy, golden tater tots are the star of this dish. They form a sturdy, delicious base and get perfectly crispy on top while staying tender inside.

Breakfast sausage adds savory, meaty flavor. Use your favorite pork sausage, turkey sausage, or even bacon if you prefer. The sausage adds richness and makes this casserole hearty enough to keep you full all morning.

Eggs and milk create a creamy custard. The beaten eggs and milk mixture binds everything together and bakes into a soft, creamy custard that holds the casserole together without being dry.

How to Make Tater Tot Sausage Breakfast Casserole

Step-by-Step Directions

1. Preheat your oven to 350°F. Grease a 9x13-inch baking dish with butter or nonstick spray.
2. Cook the sausage and vegetables. In a large skillet over medium heat, cook the crumbled sausage until browned, about 5 to 7 minutes. Add the diced onion and bell pepper and cook for another 3 to 4 minutes until softened. Drain any excess grease and set aside.
3. Whisk together the eggs and seasonings. In a large mixing bowl, whisk together the eggs, milk, garlic powder, onion powder, salt, and pepper. If you like a little kick, add salsa or hot sauce.
4. Layer the casserole. Arrange half of the frozen tater tots in an even layer at the bottom of the prepared baking dish. Top with the cooked sausage and sautéed vegetables, then sprinkle with 1 cup of shredded cheddar cheese.
5. Pour the egg mixture over the top. Pour the whisked egg mixture evenly over the sausage and cheese layer. Gently press down with a spatula to make sure the egg mixture seeps into all the layers.
6. Add the remaining tater tots and cheese. Arrange the remaining tater tots on top in a single layer. Sprinkle the remaining 1 cup of shredded cheese over the tater tots.
7. Bake until golden and set. Cover the dish with aluminum foil and bake for 45 minutes. Remove the foil and bake for an additional 15 to 20 minutes, until the eggs are fully set and the top is golden brown and crispy.
8. Let it cool and serve. Let the casserole cool for 5 to 10 minutes before slicing and serving. This helps it set up and makes it easier to cut clean slices.

Quick Tip: If you're making this the night before, assemble the casserole through step 6, cover it tightly with plastic wrap or foil, and refrigerate overnight. In the morning, bake as directed, adding an extra 10 to 15 minutes to the baking time since it's coming straight from the fridge.

Little Moments in the Kitchen

The first time I made this casserole, Adam wandered into the kitchen and said, "Mom, it smells like McDonald's in here. Are we having breakfast from a restaurant?" I laughed and told him it was just tater tots and sausage. He looked skeptical. "But tater tots are for lunch, not breakfast."

I served him a big slice anyway. He took one bite, paused, then said, "Wait, this is actually amazing. Can we have this every Saturday?" Now he calls it "the breakfast with the crunchy potatoes," and Grandma Viola says it reminds her of the hearty, old-fashioned casseroles her church ladies used to bring to potlucks.

Substitutions for Tater Tot Sausage Breakfast Casserole

• Sausage: Swap pork sausage with turkey sausage, chicken sausage, crumbled bacon, or diced ham. You can also use plant-based sausage for a vegetarian version.
• Tater tots: Use frozen hash browns or diced frozen potatoes instead of tater tots.
• Milk: Use half-and-half for a richer custard, or use almond milk or oat milk for a dairy-free option.
• Cheese: Try Monterey Jack, pepper jack, mozzarella, or a Mexican cheese blend instead of cheddar.

Variations on Tater Tot Sausage Breakfast Casserole

• Sausage Tater Tot Casserole No Eggs: Skip the eggs and layer the tater tots, cooked sausage, and shredded cheese in the dish. Pour 1 can of cream of mushroom soup mixed with ½ cup milk over the top, then bake at 350°F for 45 to 50 minutes.
• Sausage Cream Cheese Tater Tot Breakfast Casserole: Add 4 ounces of softened cream cheese to the egg mixture and whisk until smooth for an extra-creamy, rich casserole.
• Tater Tot Breakfast Casserole with Cottage Cheese: Replace ½ cup of the milk with ½ cup cottage cheese for a high-protein, tangy twist.
• Tater Tot Sausage Bacon Breakfast Casserole: Use half sausage and half crumbled bacon for a double-meat version.
• Overnight Sausage Tater Tot Breakfast Casserole: Assemble the casserole the night before, cover tightly, refrigerate, and bake fresh in the morning. Add 10 to 15 extra minutes to the baking time.

• Large skillet: For browning the sausage and sautéing the vegetables.
• Large mixing bowl: For whisking together the eggs, milk, and seasonings.
• Aluminum foil: Essential for covering the casserole during the first half of baking to prevent over-browning.
