Tater Tot Breakfast Casserole

We have a smaller house so we don’t generally have friends or family staying for the night but, occasionally, we have someone passing out on the sofa because of one too many mimosas. That’s when a great, hearty breakfast casserole comes in handy.

If you’re anything like us, you LOVE tater tots. They’re somewhat addicting with their crispy exterior and tender interior. I think they may be even better than french fries….at least the one’s you make at home. So, it’s only natural that I’d find a way to start the day with a plate filled with tater tots and this Tater Tot Breakfast casserole is sure to please!

What is Tater Tot Breakfast Casserole?

It you’ve ever had Tater Tot Casserole then this is very similar except it’s made with eggs, cheese, sausage, peppers and onions. It’s much more breakfast-y than a typical Tater Tot Hotdish.

If you’re wondering what a Tater Tot Casserole is, it’s just a casserole made with a base of tater tots that’s baked in a sauce with some sort of meat and vegetables. It’s also known as a hotdish in the midwest and, believe it or not, it’s not very common in the Northeastern US. So, I’m blazing trails over here on the east coast with this recipe.

How To Make Tater Tot Breakfast Casserole

Sunday morning breakfast is a big deal around here so I like to make something extra comforting like bacon and pancakes BUT I usually lean towards something easier like a breakfast casserole

This Tater Tot Breakfast Casserole recipe is super easy to make and you can even make it the day before so all you have to do is pop it in the oven when you wake up in the morning making this a go-to on the regular.

  1. Arrange the tater tots in the bottom of a 13×9 inch baking dish coated with cooking spray.
  2. Sprinkle the tater tots with cooked, crumbled sausage and sauteed peppers and onions.
  3. Sprinkle the casserole with half the cheese and then pour the egg mixture over the cheese.
  4. Sprinkle with the remaining cheese and allow to rest for 30 minutes or overnight.
  5. Bake the tater tot casserole in the oven for 1 hour or until cooked all the way through.
  6. Allow the casserole to rest for 15 minutes before cutting.
  7. Serve with chopped fresh parsley, hot sauce and sour cream, if desired.

To Freeze or Not To Freeze

The best thing about this breakfast casserole is that you can make it in advance but I wouldn’t recommend freezing it. I found that when I freeze the casserole both before baking and after baking it tends to separate when reheated. The raw eggs, when frozen, get weird, too. I know…that’s a highly scientific way to describe it but that’s all I got for you. 

My recommendation is to just assemble the day before and bake right before serving. It’s simple enough and doesn’t take much time at all.

What To Serve It With

Because this breakfast casserole is a one pot deal, for the most part, I like to keep things simple with a fresh green salad (for something more brunch-y) or this easy Fruit Salad is light and quick.

If you need to round out your breakfast even more, you can serve with these easy Smoked Salmon Canapes and a sparkling mimosa. When I’m serving it for a brunch spread, I also like to include these easy Overnight Oats or a simple smoothie recipe to keep everyone happy and satisfied.
