Easy Tater Tot Breakfast Casserole Recipe
When my kids were little, they didn’t really like potatoes – not baked, or mashed, or roasted – unless they were French Fries or Tater Tots. Kids are so weird.
This tater tot casserole was (and still is!) always a hit when I serve it. It’s made with breakfast sausage, vegetables, cheese, simple seasonings, and tater tots, of course. It’s crazy easy, hearty and filling, and just plain delicious. There’s also no flour, so it’s a great option for anyone with gluten sensitives.
Enjoy it the same day you bake it or prep and stash it in the fridge overnight for an even easier breakfast the next morning. I’ve been known to serve it for dinner, too. We all love it.

Cheesy Tater Tot Casserole Ingredients
You’ll need just a short, simple list of ingredients to make this cheesy tater tot casserole:
(Scroll below to the printable recipe card for details and measurements.)
- Tater Tots – frozen tater tots. We’re partial to the Ore-Ida brand, but any are fine.
- Breakfast sausage – or you can use mild Italian or hot sausage, if you prefer.
- Vegetables – onion, red bell pepper, and garlic.
- Eggs – you’ll need 8 large eggs, which makes this tater tot casserole thick and filling.
- Milk – whole milk is my preference for taste and creaminess. 2% is fine, but I wouldn’t go below that. If you want it even richer, use half-n-half.
- Cheese – we love shredded Colby jack cheese. Cheddar cheese or pepper jack would also work really well.
- Seasonings – simple seasonings like salt, pepper, garlic powder, and dry ground mustard add to the delicious flavor. The mustard is very subtle, but you can omit it, if preferred.
No Need To Thaw The Tater Tots

How to Make Tater Tot Breakfast Casserole
You only need a few minutes to prep this easy casserole and the fact that the tots don’t need to be defrosted first, makes it even easier! Here’s a brief summary of the steps:
(For all the details, scroll down to the complete printable recipe card.)
- Cook the sausage and vegetables. Drain off grease and place in a 9×13 casserole dish.
- Whisk together the eggs, milk, and seasonings. Pour over cooked veggies.
- Sprinkle with half the cheese and the tater tots.
- Bake, uncovered, for about 40 minutes. Sprinkle with remaining cheese and cook a few minutes more.
- Let stand for a couple minutes, then serve and enjoy!

Make Ahead and Storage
- Can you make tater tot breakfast casserole ahead of time? If you would like to make tater tot casserole ahead of time, prep it without the tater tots, then cover it with foil and place it in the refrigerator overnight. The next day, top it with the tater tots and bake it according to the directions. You certainly can assemble the entire thing the night before, but I recommend waiting to add the tater tots right before baking so they don’t get soggy.
- How to store leftovers? Cool completely, then place in an airtight container and keep in the fridge for up to 3 days.
- Can you freeze tater tot breakfast casserole? Yes! This casserole freezes well. Allow to cool completely after baking, then transfer to a freezer-safe, airtight container (or portion out into individual servings.) It can be stored up to 2 months. Thaw in the fridge overnight.
