Back-to-school season always feels like a whirlwind in our house. Between packing lunches, organizing school supplies, and managing two full-time jobs, I’m constantly looking for make-ahead breakfast recipes that are quick, hearty, and most importantly, family-approved.

One of our current favorites? This Breakfast Tater Tot Casserole with Sausage. It’s warm, savory, satisfying, and can double as breakfast-for-dinner (a total win on chaotic weeknights). Whether you're meal prepping for the week or feeding a crowd during weekend brunch, this casserole is a total lifesaver.

Why You'll Love This Breakfast Casserole

This tater tot breakfast casserole is everything you want in a family meal:

As a busy mom, these are the kinds of recipes I keep on repeat. You can prep it ahead of time and just pop it in the oven when you're ready. Plus, it reheats beautifully for leftovers.

Ingredients for Breakfast Tater Tot Casserole

Here’s what you’ll need to whip up this hearty dish:

1-pound fresh sausage (pork, turkey, or chicken sausage all work well)

1 medium onion, diced

1 red bell pepper, chopped

1 cup shredded sharp cheddar cheese

1 cup shredded mozzarella cheese

12–16 large eggs (depending on how eggy you like it)

2 cups milk

1 tablespoon each salt, garlic powder, and black pepper

1 bag frozen tater tots (enough to cover the top of a 9x13" pan)

Feel free to adjust the veggies based on what your family likes. This recipe is super flexible!

How to Make the Casserole

Step 1: Preheat Oven
Preheat your oven to 350°F and spray a 9x13" baking dish with non-stick cooking spray.

Step 2: Cook the Sausage and Veggies
In a large skillet over medium-high heat, cook the sausage, onions, and bell peppers together. Crumble the sausage as it cooks until browned and cooked through. Drain excess grease, then transfer the mixture to your prepared baking dish.

Step 3: Mix the Egg Base
In a large bowl, whisk together the eggs, milk, shredded cheeses, and seasonings. Pour this mixture evenly over the sausage and veggie layer in your pan. Stir gently to combine everything.

Step 4: Add the Tater Tots
Top the casserole with a single, even layer of frozen tater tots. Don’t press them in, just lay them on top like a crispy crown.

Step 5: Bake
Place the casserole in the oven and bake for about 40 minutes, or until a knife inserted in the center comes out clean and the top is golden and crispy. Let it cool for 10 minutes before serving to allow the casserole to set.
