The BEST Breakfast Casserole with Tater Tots

A breakfast casserole is one of my favorite hacks for getting everyone fed on a weekend morning without turning the kitchen into a mess. I throw this together, slide it in the oven, and suddenly I have 40 minutes to drink my coffee while this casserole cooks!

With savory turkey sausage, fluffy eggs, peppers and onions, crispy tater tots, and melty cheddar, it's basically every good breakfast thing thrown into one dish, and it works so well. I'll make this on a Sunday and have slices ready to reheat all week long, which makes it one of my most-used meal prep breakfasts.

If you're a casserole person like me (and once you make this, you will be), you have to try my Croissant Breakfast Casserole, my Sweet Potato Egg Breakfast Casserole, and my Everything Bagel Breakfast Casserole. They're all in heavy rotation around here for good reason!

Why You'll Love This Tater Tot Egg Breakfast Casserole

It feeds a crowd! One 9×9 dish serves 6 to 8 people, which makes it perfect for brunch gatherings, holiday mornings, or Sunday meal prep.
The tater tot base is pure genius. Forget making hash browns from scratch. Frozen tater tots crisp up beautifully on the bottom and act as the ultimate starchy base.
It's packed with protein. Between the turkey sausage, eggs, and cottage cheese (yes, cottage cheese, trust me!), each slice delivers serious staying power to keep everyone full all morning.
Make it ahead with ease. You can assemble this the night before and pop it in the oven the next morning. Meal prep wins!
Totally customizable. Swap the sausage, change up the veggies, or adjust the cheese. This recipe is super flexible and works with whatever you have on hand.

Ingredients Needed

Here's a little bit about everything that goes into this tater tot breakfast casserole:

Frozen tater tots: For ease, I just use frozen tater tots as the base of this tater tot egg breakfast casserole. No thawing needed! They go in straight from frozen and bake up perfectly golden.
Olive oil: Used to sauté the veggies. Avocado oil works great here too.
Yellow onion: To build flavor right from the start. White onion works as a substitute.
Red bell pepper: For a little sweetness and that classic breakfast flavor. Feel free to swap in green or orange pepper.
Ground turkey sausage: I love using ground turkey sausage for this. It's leaner than pork sausage and still incredibly flavorful. Any breakfast sausage in tube form works here, including pork or chicken sausage.
Eggs: To bind everything together and add extra protein. Use large eggs for best results.
Cottage cheese: This is my secret ingredient! It blends right into the egg mixture and makes the eggs unbelievably fluffy and creamy without any detectable cottage cheese texture or taste. Full-fat or 2% both work well.
Shredded cheddar cheese: Melted on top! Pepper jack or Monterey Jack are fun alternatives if you want a little kick.
Green onion: Totally optional but highly recommended as a garnish.

Substitutions & Additions

Swap the protein. Ground pork sausage, chicken sausage, or even crumbled bacon all work in place of turkey sausage. You can also go veggie and leave the meat out entirely by using a vegetarian meat alternative or adding extra veggies.
Change up the veggies. Mushrooms, spinach, jalapeño, or zucchini are all great additions. Sauté any extra veggies along with the onion and pepper.
Mix up the cheese! Try a blend of cheddar and pepper jack for a spicy kick, or go with gruyere for something special.
Add heat. A pinch of red pepper flakes or a dash of hot sauce in the egg mixture gives this a nice kick.

How to Make Easy Tater Tot Breakfast Casserole

Step 1: Preheat your oven to 375°F and grease a 9×9 baking dish. Spread the frozen tater tots in an even layer across the bottom.

Step 2: In a large sauté pan, heat olive oil over medium-high heat. Add the diced onion and red pepper and cook for 3 minutes. Add the turkey sausage and cook until no longer pink, breaking it up along the way. Pour the mixture evenly over the tater tots.

Step 3: Whisk together the eggs, cottage cheese, salt, pepper, onion powder, and garlic powder. Pour over the tater tot and sausage layer, spreading as evenly as possible. Top with shredded cheddar cheese.

Step 4: Bake for 40–45 minutes, or until the center is set and no longer jiggly. If the cheese starts browning too quickly, loosely cover with foil halfway through. Let rest for at least 15 minutes before slicing.

Erin's Expert Recipe Tips

The cottage cheese is non-negotiable (in my opinion!). I know it sounds a little unexpected, but it completely disappears into the egg mixture and creates the fluffiest, creamiest texture. Give it a chance!
Use a 9×9, not a 9×13. A 9×9 dish gives you a nice thick casserole with a good egg-to-tater-tot ratio. A larger pan will spread it too thin.
Make it ahead! Assemble the casserole the night before up to the baking step, cover with plastic wrap, and refrigerate. In the morning, pull it from the fridge, let it sit for 15–20 minutes at room temp, and bake as directed. You may need to add 5 extra minutes of bake time.
Serve it with: A fresh fruit salad, a simple green salad, or pair it with my Easy Roasted Breakfast Potatoes if you're going all out for a brunch spread! It's also amazing with my Coffee Protein Smoothie!

Frequently Asked Questions

Can I use hash brown patties instead of tater tots?

Yes, hash brown patties work great as a substitute! Just layer them across the bottom of the baking dish the same way you would the tater tots.

Why does my casserole still look jiggly in the center?

Give it more time! The egg layer can take the full 45 minutes, especially if your oven runs cool. The center should be completely set (not liquidy) before you pull it out.

Can I use egg whites instead of whole eggs?

You can swap in egg whites, though the texture will be slightly less rich. Use about 16 egg whites in place of 8 whole eggs.

Storing Leftovers

Let the breakfast casserole with tater tots cool completely before transferring to an airtight container. It'll keep in the fridge for up to 4 days, making it a great option for weekday breakfasts. Just reheat individual slices in the microwave for 1–2 minutes or in the oven at 350°F for about 10 minutes until warmed through.

Can I freeze this casserole?

Yes! This tater tot casserole freezes really well. Slice it up, wrap each piece individually in plastic wrap and foil, and store in the freezer for up to 2 months. To reheat, pop it in a 350°F oven for 20–25 minutes or microwave on 50% power until heated through.
