2 cups shredded cheddar cheese
8 large eggs
1 cup whole milk
1 teaspoon garlic powder
1 teaspoon salt
½ teaspoon black pepper

How to Make Cheesy Tater Tot Breakfast Casserole

Preheat your oven to 375°F and grease a 9×13-inch baking dish.
In a skillet over medium heat, cook the ground sausage until browned and no longer pink. Drain excess grease and set aside.
In the same pan, sauté the diced onions and bell peppers for 3 to 4 minutes until slightly soft. Set aside.
In a large mixing bowl, whisk together the eggs, milk, garlic powder, salt, pepper, and smoked paprika until well combined.
In the baking dish, layer cooked sausage, sautéed vegetables, and 1½ cups of shredded cheese. Pour the egg mixture evenly over the top. Arrange frozen tater tots in a single layer across the surface.
Bake uncovered for 40 to 45 minutes, or until the eggs are set and the tater tots are golden and crispy.
Sprinkle with the remaining ½ cup of cheese and return to oven for 5 minutes to melt. Garnish with parsley before serving.

Serving Suggestions for Brunch or On-the-Go

This cheesy tater tot breakfast casserole is best served warm, right out of the oven. Cut it into squares and serve alongside fresh fruit, toast, or a light arugula salad for contrast. It pairs beautifully with fresh orange juice, hot coffee, or a creamy iced latte.

If you’re planning brunch, keep it simple with a fruit tray, yogurt parfaits, and mini muffins. For a heartier meal, add scrambled eggs or a breakfast burrito bar.

Want it grab-and-go style? Let the casserole cool, slice into portions, wrap in foil, and refrigerate. Reheat a slice in the toaster oven for a perfect quick breakfast during the week.

End the meal on a sweet note with a simple fruit compote or cinnamon rolls if you’re entertaining.

Variations to Make It Yours

Use ground turkey sausage for a lighter version without sacrificing flavor.
Add chopped spinach, mushrooms, or zucchini for more vegetables and color.
Swap cheddar for Monterey Jack, Pepper Jack, or mozzarella to change the flavor profile.
For spice lovers, toss in chopped jalapeños or a dash of hot sauce into the egg mix.
Make it vegetarian by using plant-based sausage or skipping the meat entirely.

How to Store and Reheat Leftovers

To store, let the casserole cool completely, then cover the dish tightly with foil or transfer slices into airtight containers. Refrigerate for up to 4 days.

To reheat, place a slice on a microwave-safe plate and heat for 60–90 seconds. For a crispier texture, reheat in a toaster oven or air fryer at 375°F for 5–7 minutes.

To freeze, wrap individual slices in foil or plastic wrap, then place in a zip-top freezer bag. Label and store for up to 2 months. Thaw in the fridge overnight before reheating.

Pro Tips for the Best Tater Tot Casserole

• Always use frozen tater tots straight from the bag. Thawed tots get soggy.

• Let the casserole rest 5–10 minutes after baking. This helps it firm up for cleaner slices.

• Use a mix of cheeses if you like layers of flavor. Sharp cheddar and Monterey Jack are a winning combo.

• Don’t overmix the eggs, whisk just enough to blend yolks and whites smoothly.

• Cook your sausage thoroughly and drain it well to avoid greasy casserole bottoms.

Common Mistakes to Avoid with Breakfast Casserole Tater Tots

• Using too much liquid can make the casserole rubbery. Stick to 1 cup milk for 8 eggs.

• Don’t skip sautéing the vegetables. Raw peppers can release too much water and stay crunchy.

• Avoid overbaking. Check around 40 minutes, if it’s golden and set, it’s ready.

• Too many toppings (like extra cheese) on top of the tater tots can keep them from crisping up.

• Using low-fat cheese can result in a less creamy texture. Stick with full-fat cheddar for best melt and flavor.
