Step-by-Step Recipe for Cheesy Tater Tot Breakfast Casserole

This easy casserole comes together in just a few simple steps. Follow along for a foolproof way to make a hearty and cheesy tater tot breakfast casserole that everyone will enjoy.

Prep Time: 15 minutes

Cook Time: 45 minutes

Total Time: 1 hour

Servings: 6–8

Prepare the Baking Dish

Preheat your oven to 350°F (175°C).
Lightly grease a 9×13-inch (33×23 cm) baking dish with butter or non-stick cooking spray to prevent sticking.

Cook the Meat and Vegetables

In a large skillet, cook 1 lb (450 g) breakfast sausage over medium heat until browned, breaking it apart with a spatula.
If desired, add 1 diced onion and sauté until soft and translucent.
Drain excess grease and set aside.

Mix the Egg and Cheese Custard

In a large mixing bowl, whisk together:
- 8 large eggs
- 1 cup (240 ml) whole milk or half-and-half
- 1 teaspoon salt, ½ teaspoon black pepper, and 1 teaspoon garlic powder
Stir in 1 cup (100 g) shredded cheddar cheese.

Assemble the Casserole

Spread the cooked sausage and onion mixture evenly on the bottom of the baking dish.
Pour the egg and cheese mixture over the sausage layer.
Arrange 32 oz (900 g) frozen tater tots in a single, even layer on top.
Sprinkle with the remaining 1 cup (100 g) shredded cheddar cheese for a cheesy, golden finish.

Bake the Casserole

Place the dish in the preheated oven and bake for 40–45 minutes, or until the eggs are fully set and the top is golden brown.
If the top browns too quickly, cover loosely with aluminum foil during the last 10 minutes of baking.

Cool, Slice, and Serve

Allow the casserole to cool for about 5–10 minutes before slicing.
Garnish with fresh parsley or green onions if desired.
Serve warm with fruit, toast, or a fresh salad for a complete breakfast or brunch.

Delicious Variations and Serving Ideas

One of the best things about this tater tot breakfast casserole is how easy it is to customize. Whether you want a meaty, vegetarian, or spicy twist, there are endless ways to make it your own. Here are a few variations and serving suggestions to inspire you:

1. Loaded Casserole for Extra Flavor

Turn your breakfast bake into a loaded tater tot casserole by adding colorful vegetables like bell peppers, mushrooms, or spinach. You can also sprinkle in some crumbled bacon along with sausage for double the savory goodness.

2. Vegetarian Option

Skip the meat and bulk up your casserole with veggies. Try roasted zucchini, broccoli, or sautéed mushrooms for a hearty but lighter version. Using a blend of cheeses such as mozzarella and pepper jack will still give you that indulgent, cheesy finish.

3. Spicy Kick

For heat lovers, add diced jalapeños, green chilies, or even a pinch of cayenne pepper to the egg mixture. Top with a drizzle of hot sauce or salsa before serving for a bold morning bite.

4. Overnight Make-Ahead Version

If you’re hosting brunch or preparing for a holiday morning, assemble the casserole the night before. Cover and refrigerate overnight, then bake in the morning. This not only saves time but also allows the flavors to meld together beautifully.

Serving Ideas

Pair with a fresh fruit salad for a lighter balance.
Serve alongside buttery toast or biscuits for a classic breakfast spread.
Offer toppings like sour cream, chives, or avocado slices so everyone can personalize their plate.
Make it brunch-worthy by serving with mimosas, coffee, or fresh juice.

This casserole is hearty enough to stand on its own but versatile enough to shine in a full breakfast or brunch spread.

Tips for Storing, Freezing, and Reheating

This casserole isn’t just delicious fresh out of the oven—it also stores and reheats beautifully, making it perfect for meal prep, leftovers, or make-ahead breakfasts. Here’s how to keep it tasting as good as day one:

1. Storing in the Refrigerator

Allow the casserole to cool completely before storing.
Cover the baking dish tightly with plastic wrap or transfer slices into airtight containers.
Store in the fridge for up to 3–4 days.

2. Freezing for Later

To freeze the entire casserole: Bake as directed, let it cool completely, then wrap tightly in plastic wrap followed by aluminum foil.
To freeze individual portions: Slice the casserole into squares, wrap each piece in plastic wrap, and place them in a freezer-safe bag or container.
Frozen casserole will keep well for up to 2 months without losing flavor or texture.

3. Reheating Instructions

In the oven (best method): Preheat to 350°F (175°C), cover the casserole with foil, and bake for 20–25 minutes (whole dish) or 10–12 minutes (individual slices).
In the microwave (quick method): Heat individual portions on a microwave-safe plate for 1–2 minutes, checking halfway through.
For a crispy top, add a sprinkle of shredded cheese before reheating in the oven.

Extra Tips for Success

Always cool the casserole before refrigerating or freezing to prevent sogginess.
Label your freezer containers with the date so you know how long it’s been stored.
If baking directly from frozen, add about 15–20 extra minutes to the cooking time.

With these storage and reheating tips, you can enjoy your cheesy tater tot breakfast casserole any time—whether it’s fresh from the oven, a busy weekday morning, or a make-ahead holiday breakfast.
