    ❤️ Reasons to Love This Recipe

    • It's a crowd pleaser. This vegetarian tater tot breakfast casserole can easily feed nine hungry people. You will certainly have them asking for the recipe as well!
    • It's easy. There really isn't much that needs to be done to prepare this casserole. The hardest part might be chopping the veggies and grating the cheese, but even that is no biggie. You could always buy pre-grated cheese, but we've found that freshly-grated cheese melts better.
    • It's make ahead friendly. You will love that you can prepare everything the night before and store the whole casserole covered in your fridge overnight. Then, all you have to do the next morning is bake and enjoy!
    • And of course, it's vegetarian!

    🥔 Ingredients

    Vegetarian Tater Tot Breakfast Casserole ingredients
    • Frozen Tater Tots.
    • Olive oil. This is used to sauté the mushrooms and onions.
    • Sweet onion. Diced.
    • Sliced cremini mushrooms. You can substitute your favorite mushroom variety.
    • Milk.
    • Heavy cream. For a lower fat version, you can substitute half and half or milk.
    • Salt. Salt enhances the flavor of this breakfast casserole. You can add more or less according to your taste.
    • Smoked paprika. We love the flavor that smoked paprika adds, but you can substitute regular paprika, or ¼ teaspoon of cayenne pepper.
    • Large eggs. Beaten.
    • Small red bell pepper. Diced. Adds color and flavor.
    • Small green bell pepper. Diced. Adds color and flavor.

    💡 Variations

    • Spicy - Substitute cayenne pepper for the smoked paprika and add a diced jalapeño or two.
    • Meat lovers - Add cooked sausage, bacon, or ham. You can either leave the mushrooms or substitute them for your breakfast meat of choice. Add the cooked meat along with the cooked onions.

    🌡️ Storage

    We recommend freezing any leftovers right away in individual freezer-safe meal prep containers. Casserole will keep in the freezer for up to 3 months. Reheat individual servings in the microwave on high until heated through.
