What You’ll Need
Kitchen Equipment
You’ll need a large skillet, a whisk, a couple of mixing bowls, a 9×13-inch baking dish, and measuring cups and spoons. A cheese grater helps if you’re shredding fresh cheese, and a meat masher is handy for cooking the sausage evenly.
Ingredients Overview
The sausage brings a rich, savory kick. Frozen tater tots add a crispy, golden layer that holds up beautifully under the creamy eggs. Milk gives the casserole a soft, fluffy texture, while cheddar and mozzarella melt together for the ultimate cheesy goodness. You can toss the tater tots in straight from the freezer. This recipe easily halves or doubles for smaller or larger gatherings.
How to Make Tater Tot Sausage Breakfast Casserole
Prepare the Sausage
Start by preheating your oven to 350ºF. Brown 2 pounds of hot breakfast sausage in a skillet over medium heat until fully cooked, breaking it apart as it browns. Drain off any excess fat. If you like, stir in diced onions or bell peppers for an extra burst of flavor.
Combine the Base
In a large bowl, mix the frozen tater tots, cooked sausage, 1½ cups cheddar, and ½ cup mozzarella. Stir everything well so each bite has a little of everything. Pour this mixture into a lightly greased 9×13-inch baking dish and spread it evenly.
Make the Egg Mixture
In a separate bowl, whisk together 8 eggs, 2 cups of milk, salt, pepper, garlic powder, and onion powder until smooth. Pour this evenly over the tater tot and sausage mixture so it seeps through all the layers.
Bake Until Perfect
Place the dish uncovered in the oven and bake for 60 to 70 minutes. The casserole is ready when the top is golden and the eggs are set. To check, gently jiggle the center — it should be firm, not liquid.
Cool and Serve
Let the casserole rest for 5 to 10 minutes before cutting. This helps it set and makes slicing easier. Top with green onions, salsa, or hot sauce for a flavor boost. Serve it alongside Brioche French Toast Casserole for a Crowd for a delicious brunch spread.

Make-Ahead and Storage Tips
You can assemble this casserole a day ahead and refrigerate it overnight. Just bake it straight from the fridge, adding about 10 extra minutes to the cooking time. For freezing, wrap the unbaked dish tightly and freeze for up to 2 months. Thaw it completely in the fridge before baking. To reheat a baked casserole, cover with foil and bake at 350ºF for 30 to 40 minutes until warmed through. This makes it ideal for holidays or busy weekday mornings.
Recipe Variations and Add-Ins
You can swap the sausage for cooked bacon or diced ham for a twist. Add diced bell peppers, mushrooms, or spinach for extra color and nutrition. For a spicy kick, use pepper jack cheese or add a few dashes of hot sauce to the egg mix. Want a lighter option? Try turkey sausage and reduced-fat cheese. You can also make it gluten-free by checking your sausage and tater tot brands for certification.
Serving Suggestions
This casserole pairs perfectly with a bowl of fresh fruit salad, a glass of orange juice, or a hot cup of coffee. It also fits beautifully on any brunch table next to Fluffy Japanese Soufflé Pancakes or Air Fryer Egg and Cheese Toast. For something sweet on the side, try Peach Oatmeal Breakfast Cookies.
Helpful Tips for the Best Results
Use good-quality sausage for the richest flavor. Don’t thaw the tater tots — they’ll stay crispier if you add them frozen. Always let the casserole rest before slicing to keep it from falling apart. Shred your cheese fresh instead of using pre-shredded, as it melts more smoothly. If you’re unsure whether it’s cooked through, check that the internal temperature reaches about 160°F.
