Best Tater Tor Casserole

This tater tot casserole is a cross between a quiche and a casserole. It has plenty of eggs and vegetables. I developed this breakfast casserole, especially for vegetable lovers. (Hi! 🙋🏼‍♀️) I didn’t include a protein in it but you can add one pound of breakfast sausage or one pound of cooked and chopped bacon if you want. It’s honestly delicious with sausage or bacon and without it.

The full recipe is at the end of the post.

  • Tater tots, frozen
  • Mushrooms, sliced. The mushrooms can be a mix or whatever you have on one hand, baby portobello, shiitake, white cap, etc. Furthermore, if you don’t like mushrooms you can omit them altogether.
  • Fresh spinach
  • Eggs
  • Red bell peppers, diced
  • Onion, diced
  • Cheddar cheese, grated. You can use Colby, Havarti, or Monterrey cheese.
  • Half and half. Half and half is a mixture of equal parts cream and whole milk. Therefore, you can substitute 1 cup heavy cream and 1 cup whole milk. You can also use all whole milk but your casserole will not be a rich and creamy.
  • Sun-dried tomatoes. You can sub canned or freshly diced tomatoes, drained well. Or you can sub roasted red peppers.
  • Jalapeño, diced. Remove seeds, veins & pith if you want less heat. You can also substitute pablono peppers or a green bell pepper if you don’t want the heat whatsoever.
  • Salt and pepper to taste
  • Parsley to garnish

how to make tater tot casserole
Can I make this ahead of time and freeze it?

You can make components of this dish ahead of time and freeze them, like the veggies. The tater tots are already frozen. I would just crack the eggs and whisk right before you want to make the dish, as it will taste the best.

Do I have to use a 9×13 dish?

This is the preferable dish size but if you only want to make half of the recipe, then an 8×8 dish would work. The cooking times will vary, so just make sure to be checking to see if the eggs have set, that is the most important part.

Prep Time: 15 minutes
Cook Time: 1 hour 5 minutes
Servings: 12 servings


  • 1.5 pound tater tots frozen
  • 1 cup mushrooms sliced
  • 2 cups fresh spinach
  • 8 large eggs
  • 2 medium red bell peppers diced
  • 1 medium onion diced
  • 8 ounces cheddar cheese grated
  • 2 cups half and half heavy whipping cream or whole milk
  • ½ cup sun-dried tomatoes
  • 1 medium jalapeno diced
  • Salt and pepper to taste
  • Parsley to garnish


  • In a skillet, over medium heat, sauté the onions, peppers, and mushrooms until the onions are translucent and the peppers and mushrooms are tender. Usually, 6-7 minutes and then place in a bowl and set aside.
  • In the same skillet, place the spinach on low heat and just allow the spinach to wilt. 1-2 minutes and set aside
  • In a large bowl, crack the eggs and whisk in half and half as well as salt and pepper. Whisk until well combined and the mixture is starting to become paler in color. Thiswill result in fluffier eggs.
  • Spray a 9×13 casserole dish with cooking spray. Place the veggie mixture and the spinach in the dish and spread it out evenly. Pour the egg mixture over the veggies. Layer in 3/4 of the cheese into the dish, and set the remaining cheese aside until later.
  • Layer the tater tots evenly across the whole dish. Place in the oven and bake for 55-65 minutes at 350 degrees. The eggs should be almost set and just give a slight jiggle.
  • Pull the dish out and cover the top with the remaining cheese. Place back in the oven for about 8-10 minutes or until the cheese is melted. Take out and garnish with parsley. Enjoy!
