Ingredients You’ll Need

Tater Tot Breakfast Casserole

  • 2 pounds hot breakfast sausage
  • 1 30–32 ounces bag frozen tater tots
  • 1 teaspoon salt
  • 1/2 teaspoon pepper
  • 1/4 teaspoon garlic powder
  • 1/4 teaspoon onion powder
  • 1–1/2 cups shredded cheddar cheese
  • 1/2 cup mozzarella cheese
  • 8 eggs
  • 2 cups milk

Chef notes:

  • Use hot sausage for a kick.
  • Shred cheese fresh for meltier texture.
  • Room-temperature eggs bind better.

How to Make It

  1. First, preheat the oven to 175°C (350°F) and spray a 9×13-inch pan.
  2. Then, heat a large skillet over medium and add the sausage; cook until crumbly and browned, and listen for that satisfying sizzle. Drain off excess grease.
  3. Next, in a large bowl toss the browned sausage with the cheddar, mozzarella, and frozen tater tots until they look evenly coated.
  4. Transfer this mix into the prepared pan and spread it into an even layer; you should see tots peeking through the cheese.
  5. Meanwhile, whisk together the eggs, milk, garlic powder, onion powder, salt, and pepper until smooth and slightly frothy.
  6. Pour the egg mixture over the tater tots, then gently stir once so eggs settle around the pieces; do not overmix.
  7. Finally, bake for about 60 minutes. The casserole is done when the top looks set, edges are golden, and a knife in the center comes out mostly clean with a few moist crumbs. Let it rest 5–10 minutes before serving so it firms up.
  8. Serve warm and watch the crisp edges and bubbly cheese pull apart. For a different serving style, try it over grains like a breakfast bowl for a hearty start to the day: hearty breakfast bowls.

Kitchen Tips (From My Kitchen)

  1. Time-saver: Brown the sausage the night before and keep it chilled; then assemble in the morning.
  2. Common mistake + fix: If it comes out too soggy, bake uncovered 10–15 minutes longer to crisp the edges.
  3. Simple variation: Stir in chopped green chilies or swap hot sausage for mild and add a pinch of cayenne; also try alongside a cheesy scalloped corn casserole.

Serving Ideas

  • Brunch spread: slice and serve with fresh fruit and coffee.
  • Weeknight dinner: pair with a simple green salad and mustard vinaigrette.
  • Holiday morning: set it out buffet-style with eggs and toast.
  • For garnish: chopped chives, sour cream dollops, or salsa on the side.
    Also, if you want snack-sized portions, this recipe fits right into lists of great breakfast snacks.

Storing & Leftovers

  • Fridge: Keep in an airtight container for 3–4 days.
  • Freezer: Freeze portions up to 2 months; thaw overnight in the fridge.
  • Reheat: Warm in a 350°F oven for 10–15 minutes to keep the tots crisp.
    Leftover idea: Wrap slices in a tortilla for a quick breakfast sandwich.
