About This Recipe
This Tater Tot Breakfast Casserole combines classic breakfast flavors into one satisfying, family-friendly dish. Crispy tater tots form a comforting base and topping, while seasoned breakfast sausage and two kinds of cheese make the filling rich and savory. Eggs and milk bind everything together for a hearty casserole that’s easy to slice and serve.
The casserole is very forgiving, which makes it an excellent choice when you need to feed a group without fuss. You can assemble it the night before, refrigerate it covered, and bake it the next morning right from the fridge. That convenience makes it a favorite for holiday mornings, potlucks, or when you want to free up time to enjoy guests rather than cook.
Simple flavor adjustments let you make this casserole your own: add veggies like bell pepper or spinach, swap sharp cheddar for pepper jack for heat, or use turkey sausage for a lighter option. For crispier tots on top, bake uncovered toward the end of cooking or briefly broil for a minute or two—watch closely so they don’t burn.
Key Ingredients
Breakfast sausage: Use your favorite breakfast sausage or a mild Italian sausage for a different flavor profile. Brown and crumble it completely before combining with the other ingredients.
Frozen tater tots: Use straight from the bag; they crisp in the oven as the casserole bakes. A 24–32 ounce bag works well for a 9×13-inch pan.
Cheddar cheese: Sharp cheddar provides tang and depth. You can substitute white cheddar or a blend of cheeses to suit your taste.
Mozzarella cheese: Adds a gooey, melty texture. Freshly shredded cheese melts best—preshredded blends often contain anti-caking agents that can affect melting.
Eggs and milk: Eggs set the casserole, while milk (whole milk or half-and-half for extra richness) makes the custard silky. Adjust milk fat to preference.
Spices: Salt, black pepper, garlic powder, and onion powder are all you need for a balanced base. Feel free to add a pinch of sage, smoked paprika, or fennel for a sausage-style twist.
Instructions
STEP 1: Preheat the oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish with cooking spray or a small amount of butter and set aside. In a large skillet over medium-high heat, cook and crumble the sausage until it is no longer pink. Drain any excess fat.
STEP 2: In a large bowl, toss together the frozen tater tots, cooked sausage, shredded cheddar, and shredded mozzarella until evenly distributed.
STEP 3: Spread the tater tot and sausage mixture into the prepared baking dish in an even layer.
STEP 4: Whisk together the eggs, milk, salt, pepper, garlic powder, and onion powder in a medium bowl until combined.
STEP 5: Pour the egg mixture evenly over the tater tot mixture, pressing gently so the liquid reaches between the tots.
STEP 6: Bake uncovered for 60–70 minutes, or until the eggs are set and the center no longer jiggles. If desired, broil for 1–2 minutes at the end to brown the tops of the tater tots—watch carefully.
