The base is made with eggs, cottage cheese, pepper jack, and green chilies, creating a “chile relleno”-inspired flavor. So delicious!

Breakfast Casserole Ingredients

ingredients for easy breakfast casserole neatly arranged in bowls - green onions, cottage cheese, spices, eggs, two small cans of green chiles, bowl of milk, and grated cheese.
  • Eggs - The hearty foundation of this breakfast casserole, creating a fluffy, protein-rich base that holds everything together.
  • Cottage cheese - Adds creaminess, moisture, and extra protein while helping the casserole bake up light and tender. Whole-milk cottage cheese yields the best texture.
  • Milk - Helps loosen the egg mixture and creates a soft custardy consistency.
  • Salt, pepper, garlic powder, and oregano - A simple blend of seasonings that adds savory flavor and warmth without overpowering the dish.
  • Pepper Jack cheese - Brings melty richness and a gentle kick of spice, creating those irresistible cheesy pockets throughout the casserole.
  • Diced green hatch chilies - Add mild heat and Southwestern flavor, keeping the casserole interesting while still family-friendly. Use 2-3 small 4-ounce cans.
  • Green onions or cilantro - Provide fresh, bright flavor and a pop of color; using a mix of both works especially well.

Variations

Add any of the suggestions below to your breakfast casserole for extra protein or veggies! I will say, though, that it is truly delicious without any additions, but feel free to add:

  • Browned sausage or diced ham
  • Sautéed vegetables, like bell peppers, yellow onion, mushrooms, zucchini, or broccoli
  • Wilted spinach for extra nutrients
  • Roasted poblano or hatch chilies (instead of diced green chilies)

How to Make Breakfast Casserole

Preheat the oven to 350F.

1. Blend the eggs. Add eggs, cottage cheese, milk, spices, salt, and black pepper to a blender and blend until smooth.

2. Stir in the remaining ingredients. Reserve 1/2 cup of cheese for the top, then stir the rest into the egg mixture, along with the chilies and most of the green onions or cilantro (leave some for garnish!).

3. Assemble the breakfast casserole. Pour the egg mixture into a greased 9×13-inch baking dish. Sprinkle the remaining shredded cheese on top.

4. Bake. Place the baking dish on the lower middle rack for 35-50 minutes, or until the center puffs. Check halfway through and tent with aluminum foil if the edges are getting too dark.

5. Garnish and serve. Garnish with the remaining green onions or cilantro, then cut into squares with a sharp knife, and serve warm or at room temperature.

Chef’s Tips

  1. Stir in the cheese, don’t blend! When adding the cheese, chilies, and green onions or cilantro, be sure to stir well. Avoid blending, as this will turn the mixture green. Plus, you want to preserve some texture!
  2. Use Pepper Jack cheese for the best flavor! Pepper Jack adds a lot of flavor. If you use a different cheese, I recommend adding more spices, salt, or even chili flakes.
  3. Cover the pan with foil if it begins to brown. Keep an eye on the casserole, and if it begins to brown along the edges, place a tented sheet of foil over the top, or move to the lowest rack.
  4. The casserole is done when the center puffs. Check the center of the casserole for doneness.

Serving Suggestions

Enjoy this breakfast casserole any time of day on its own or with a breakfast side like Breakfast Potatoes or Sweet Potato Hash, fresh fruit, or simple dressed greens. Here are more of our favorite pairings:

Make-Ahead & Storage

  • Make-ahead: Feel free to assemble the breakfast casserole the day before serving. Prep it and store it in the refrigerator, then bake it in the morning. Let the pan come to room temperature before baking. Or, simply bake the day before and reheat in the morning.
  • Storage: Leftovers can be stored in an airtight container in the refrigerator for up to 4 days. Reheat in the oven or microwave until warmed through.
  • Reheat: Reheat covered in a 350F oven until internal temp reaches 145F, or reheat individual pieces in the microwave- for 2-ish minutes.

Description

This make-ahead breakfast casserole is fluffy, cheesy, and packed with protein. Perfect for busy mornings, holiday brunch, or feeding a crowd. A delicious, healthy breakfast idea, or serve it for lunch! Keto, Vegetarian, Low carb.


Ingredients

Units Scale
  • 12 large eggs
  • 2 cups cottage cheese (whole milk)
  • 1/4 cup whole milk, half and half or plain yogurt
  • 1/2 teaspoon salt
  • 1/2 teaspoon pepper
  • 1/2 teaspoon garlic powder
  • 1/2 teaspoon oregano
  • 812 ounces pepper jack cheese, grated
  • 23 cans (4-ounce) diced chilies (see notes)
  • 1/2 cup green onions or cilantro (or use half and half of both)

Instructions

  1. Preheat the oven to 350F
  2. Blend. Place the eggs, cottage cheese, milk, spices, salt and pepper in a blender, and blend until smooth.
  3. Stir. Stir in the cheese (save ½ cup for the top), chilies, and most of the green onions/cilantro (save some for garnish. Stir well (don’t blend). 
  4. Assemble. Pour into a greased 9×13-inch baking dish. Sprinkle with remaining cheese. 
  5. Bake. Bake on the lower-middle rack for 35-50 minutes, until the center puffs. Check halfway through, and tent with foil if the edges are getting too dark. 
  6. Garnish. Sprinkle with the remaining green onions or cilantro. Delicious served warm or at room temp. 

Notes

Make ahead: This meatless breakfast casserole can be prepped ahead, refrigerated, and baked in the morning. Let it come to room temp before baking. This can also be baked ahead and reheated. It’s delicious any time of day. 

Leftovers will keep up to 4 days in an airtight container in the fridge. Reheat in a warm oven or microwave. 

Cheese: Pepperjack cheese adds a lot of flavor. If using a different cheese, I would “up” the spices and salt, and maybe add some chili flakes. 

Variations: Feel free to add browned sausage, sauteed vegetables or wilted spinach. If you would like to use fresh chilies (poblano or hatch), dice and saute them, or roast, peel, and chop- you’ll need about one cup. 

If halving the recipe, use an 8×8 baking pan.

  1. I loved this recipe, but I’m unable to print it from my
    computer. I don’t want to save it on my computer. Please help!

  2. You all comtinue to improve my life with dishes like this one! Ton of flavor and a kick of heat from the pepper jack cheese. Had it with your sourdough bread and I am so happy that it stores well so I have breakfast ready for a few more days… Thanks!

  3. I prepared this the night before my 6 &7 year old grandsons came to spend the day with me, let me tell you that it did not stand a chance, no crumb left behind..this dish is going to be our new go-to for Nana days! Thank you so much!

  4. Easy and delicious!! Lighter than most egg casseroles which include potatoes or bread. Reheats beautifully for busy weeks. Will definitely be making this again. Thanks for another great recipe!

    1. Hi Jan! Reheat covered in a 350F oven until internal temp reaches 145F, or reheat individual pieces in the microwave- for 2-ish minutes. I added this to the post as well.

  5. I needed a gluten free brunch dish for my daughter’s baby shower. This was super easy and tasty! I made it the night before and baked it in the morning…a crowd pleaser!

  6. I’m not normally into egg-heavy dishes like omelettes and frittata, but this was delicious! I’ll definitely make it again.

  7. Soooo yummy!!! Added mushrooms and roasted veggies. Your recipes never disappoint. Thank you!!!

  8. Once again, perfect timing when I needed a simple dinner for family! I decided to look in the pantry and fridge for additions…I added marinated artichokes, spinach and gruyere, with fresh sage, cilantro and basil from the garden–YUM!

  9. Super easy, great flavors and loved the extra punch of protein with the cottage cheese. We added some chicken sausage and some leftover carmelized onions. Tasted delicious…will do this one again for sure!

  10. I love breakfast for any meal of the day, and this recipe hit the nail on the head in my household! Thank you so much!

  11. So delicious for Sunday brunch. Definitely will make again for our Sunday get-togethers.
    Big hit with the grandbabies.

  12. This was a big win in our house! All 4 of my kids got seconds, which says a lot. It was one of the most simple things to make and I am excited to personalize it and add some veggies and meat varieties too. I will definitely be making this again and again.

    1. Love hearing this Ginger! Let us know your favorite variations. Thanks for taking time to review.

  13. This is a very adaptable recipe. Been making a variation of this for decades called Green Chili Egg Puff, and it’s great. By adding a bit of flour and baking powder you get the “puff.” Add sautéed onions, red pepper, sausage. Sub fresh roasted and diced chilies, sub cheddar, use leftovers if any in breakfast tacos/burritos.

    1. Hi Chris, I haven’t tried this with just egg whites, so really not sure here. I like the idea of it though!
