Ingredients for Tater Tot Breakfast Casserole

This is an easy Tater tot breakfast casserole recipe and great for mixing up the ingredients. Use up leftover meat and veggies and make it a new recipe every time.

Tater Tots – Of course, tater tots are the key ingredient in this casserole. No tater tots? No problem! Layer some frozen or homemade hash browns or hashbrown patties. Sweet Potato Hashbrowns or some Homemade Shredded Hashbrowns would work too!

Bacon – We love crispy bacon in this recipe (make oven bacon to keep it easy). Feel free to swap it out for breakfast sausage, leftover ham, or even turkey sausage

Veggies – The combination of onions and green & red bell peppers not only adds flavor but also a burst of color. If you don’t have onions, you can use onion powder or garlic powder as a substitute.

Cheese – This recipe is adaptable when it comes to cheese. Choose a Mexican blend, sharp cheddar, or pepper jack cheese – they all go perfectly.


Anything goes! Try sliced mushrooms, tomatoes, olives, or even broccoli pieces to give tater tot casserole a new flair! Add seasonings or spices to your liking.

  • 20 ounces tater tots

    1. This recipe is best made ahead of time but should be fine to go straight in the oven. If you try it I would love to hear how it turns out Ann!

    1. Hi Deborah, you can leave the cheese out of this recipe and while it will change the flavor, it will still be delicious!

  1. I’m not really a big fan of eggs, but this even looks good to me. Did you put a few extra tater tots on top (per picture) or do a few just rise to the tot?

    1. The photo in the post with tots and no cheese is with the egg mixture added before baking. You can see that the eggs don’t quite cover the ingredients. You could add a few extra tots to the top if you’d like!

  2. Recipe is easy to follow until the last step – raise oven temp to 425 and cook an additional 150-20 minutes. What is the correct cooking time?

    1. Hi Gloria, we cook the casserole covered at 350°F for 40 minutes. Then we remove the cover, top with remaining cheese and bacon and cook at 425°F for an additional 15-20 minutes or until set and cheese is browned. So it would be cooked for about an hour or up to an hour and 15 minutes if needed.
