Mexican Breakfast Casserole

Happy Cinco de Mayo! Boy, do I have a treat for you today! This has seriously become one of my new favorite recipes. I can’t get enough!! I’ve made it multiple times over the past couple of weeks, and I’ve enjoyed every last bit of left-overs in between. It’s not fancy, but it’s easy, fast, and absolutely incredible!

I layer corn tortillas with lean ground beef, cheese, peppers, onions, taco seasoning, and plenty of eggs (that’s where the “breakfast” part of the title comes in!). It’s so hearty and filling that you will never feel like you’re missing out on calories or taste. Thanks to all of that lean protein, it sticks to your ribs in the best way possible!

I actually like to serve this casserole for dinner since every one of my kids loves it, but I also enjoy the left-overs for breakfast in the morning. Since it’s an easy option to make in advance, I usually prepare it in the morning and leave it in the refrigerator until I’m ready to bake it. If you’re serving this dish for brunch, however, you could easily assemble it the night before so that you only have to throw it in the oven when you wake up.

I love a minimal-prep, hands-off casserole that serves a crowd, tastes delicious, and is still healthy as well!

Prep: 15 minutes
Cook: 50 minutes
Total: 1 hour 5 minutes
Servings 8


  • 4 eggs
  • 6 egg whites
  • 1 ½ cups low-fat milk
  • 1 pound extra-lean ground beef cooked and drained
  • 1 packet taco seasoning
  • 1 red bell pepper diced
  • ¾ cup sliced green onions
  • 1 ½ cups reduced-fat Mexican blend shredded cheese divided
  • 9 corn tortillas
  • Optional: salsa chopped tomatoes, sour cream, avocado/guacamole for serving


  • Preheat oven to 350 degrees F. Spray a large 13-inch by 9-inch baking dish with cooking spray and set aside.
  • In a bowl, stir together ground beef and taco seasoning. Add red pepper, green onions, and 1 cup of the cheese. Toss together.
  • In a separate large bowl, beat eggs, egg whites, and milk with a whisk until combined.
  • Place 3 tortillas in the bottom of your prepared casserole dish, tearing if needed to fit the bottom of the dish.
  • Top the tortillas with half of the beef mixture. Layer 3 more tortillas on top, then top those tortillas with the remaining beef mixture. Top that layer with the 3 remaining tortillas. Pour egg mixture over tortillas. Sprinkle remaining ½ cup of cheese on top.
  • Cover casserole tightly and bake for about 45 minutes, or until the center is set. Remove the cover and cook for an additional 5-10 minutes to allow the cheese on top to brown and crisp slightly.
  • Serve with salsa or diced tomatoes, sour cream, avocado, or guacamole.
