Ingredients & Substitutions
Tater Tots: Frozen tater tots make this dish super easy. If you want to switch it up, you can use hash browns or even sweet potato tots for a different flavor.
Breakfast Sausage: I love using pork sausage for its rich taste, but turkey sausage is a great lighter option. You can also use vegetarian sausage if you’re looking for a meatless choice.
Cheddar and Mozzarella Cheese: Sharp cheddar adds a nice bite, while mozzarella contributes gooeyness. If you’re out of either, try Colby jack, Monterey Jack, or any cheese you enjoy. Just keep in mind the melting qualities!
Eggs and Milk: Large eggs are standard, but you can use egg substitutes or egg whites for a healthier option. For dairy-free, consider almond milk or oat milk, but the texture may be slightly different.
Onion: While optional, I recommend onions for added flavor. If you’re not a fan, you can leave them out or switch them for green onions for a milder taste.
How Do I Get Perfectly Cooked Eggs in My Casserole?
Getting the eggs just right is essential for a delicious casserole. whisking well is important, it combines the eggs and milk, ensuring even cooking. Here’s how to do it:
- Mix eggs and milk thoroughly until no streaks remain.
- Add garlic powder, salt, and pepper to the egg mixture for flavor. Adjust seasoning according to your taste.
- After layering your casserole, pour the egg mix evenly over all layers.
- Press down gently to help the tots and sausage soak up the egg mixture, ensuring a fluffy finish.
Remember not to overbake; keeping an eye on it after 40 minutes can help. You want the eggs fully set but still soft for the best texture!

- 1 (32 oz) bag frozen tater tots
- 1 lb breakfast sausage (pork or turkey)
- 1 cup shredded cheddar cheese (sharp or mild)
- 1 cup shredded mozzarella cheese
- 8 large eggs
- 1 cup milk

How Much Time Will You Need?
This delicious breakfast casserole will take about 15 minutes to prepare and 40-50 minutes to bake. You’ll spend your time layering all the yummy ingredients, and then just let the oven do the work. Perfect for a breakfast or brunch gathering!
Step-by-Step Instructions:
1. Prep Your Oven and Dish:
Start by preheating your oven to 350°F (175°C). While it warms up, take a 9×13 inch baking dish and lightly grease it with cooking spray or butter. This will help prevent the casserole from sticking!
2. Cook the Sausage:
In a large skillet set over medium heat, cook the breakfast sausage until it’s browned and fully cooked. Remember to break it into small crumbles as it cooks. If you’re using onions, toss them in when the sausage is almost done, cooking until they turn translucent. Don’t forget to drain any excess fat if needed!
3. Start Layering the Casserole:
Spread half of the frozen tater tots evenly across the bottom of your prepared baking dish. On top of the tater tots, sprinkle half of the cooked sausage, followed by half of the shredded cheddar and mozzarella cheese. Repeat this layering with the remaining tater tots, sausage, and cheeses. Trust me, it’s going to be delicious!
4. Whisk the Egg Mixture:
In a large bowl, whisk together the eggs, milk, garlic powder, salt, and pepper until everything is well combined. The eggs will add a lovely fluffiness to the dish.
5. Combine Everything:
Pour the egg mixture evenly over all the layers in your baking dish. Press down lightly to help the tater tots and sausage soak up that flavorful egg mixture.
6. Bake the Casserole:
Place the casserole in your preheated oven and bake it uncovered for 40-50 minutes. You’ll know it’s done when the eggs are set, the cheese is melted and bubbling, and the tater tots are golden and crispy on top. Your kitchen will smell amazing!
7. Let It Cool and Serve:
Once baked, take the casserole out of the oven and let it cool for about 5-10 minutes before slicing. This resting time helps it hold its shape. If you’d like, you can garnish with some freshly chopped parsley before serving. Enjoy your warm, hearty breakfast casserole!
Can I Use Other Types of Sausage?
Absolutely! You can substitute the pork sausage with turkey sausage for a lighter option, or even use a veggie sausage if you’d prefer a meatless version. Just ensure it’s fully cooked before layering in the casserole.
Can I Make This Casserole Ahead of Time?
Yes, you can prepare the casserole the night before! Simply assemble everything and cover it with plastic wrap in the fridge. Bake it the next morning, adding a few extra minutes to the cooking time if it’s cold from the fridge.
What Should I Do with Leftover Casserole?
Store any leftovers in an airtight container in the fridge for up to 3 days. To reheat, place it in the microwave or warm it in the oven until heated through. It makes for a fantastic quick breakfast option!
How Do I Customize This Casserole?
You can mix and match your favorite ingredients! Feel free to add vegetables like bell peppers or spinach for extra nutrition. You can also swap out the cheeses for your favorites; just keep in mind that different cheeses will bring varying flavors and textures.
