Ingredients & Substitutions

  • Eggs – The base of this casserole is made with eggs, providing lots of protein. If you don’t like eggs, try this recipe instead.
  • Milk – A bit of milk helps to create a creamy, fluffy texture in the casserole. I used 1% milk, but any type of milk will work.
  • Taco Seasoning – This adds a flavorful kick to the casserole. Feel free to adjust the amount or use a homemade seasoning blend to suit your taste. I used a low sodium variety.
  • Black Beans – Canned black beans are a convenient way to add protein and fiber. You can substitute with pinto beans.
  • Cheese – A shredded Mexican cheese blend melts beautifully and adds richness to the casserole. You can use cheddar, Monterey Jack, or even a dairy-free cheese if you prefer.
  • Tater Tots – These crispy potato bites form the top layer of the casserole. If you have leftover tots, try my vegetarian tater tot bake!

How to Make a Vegetarian Breakfast Casserole

In the casserole dish, whisk together the eggs, milk, and taco seasoning until well combined.
Stir in half of the shredded cheese and the black beans.
Add the tater tots on top of the egg mixture, spreading them out in a single layer.
Top with remaining cheese and cover tightly with aluminum foil.
Bake for 40-50 minutes, or until the egg mixture is set and the tater tots are golden brown.
Remove the foil and continue to bake for 5-7 minutes until the cheese is brown on top. Add toppings and enjoy.

Frequently Asked Questions

  • Is this recipe healthy? While tater tots might not be the first thing that comes to mind when you think of healthy ingredients, this casserole offers a balance of protein, carbs, and fats. The eggs and black beans provide a good source of protein and fiber, making it a filling and satisfying meal.
  • Can I add veggies? Yes! This recipe would be great with chopped spinach or finely diced peppers and onions.
  • Can I make a double batch? I haven’t tested a larger batch, so I can’t say for sure. I think you could double it and bake it in a larger pan, but you’d need to adjust the cooking time.

What to Serve with This Casserole

This vegetarian breakfast casserole pairs perfectly with my creamy fruit salad. It’s also great with a drizzle of my cilantro sauce on top for an extra burst of flavor. For a homemade salsa option, try my 5 minute blender salsa.

How to Store Leftovers

Store any leftover casserole in an airtight container in the refrigerator for up to 5 days. To reheat, simply pop a portion in the microwave or warm it in the oven until heated through.
