What Makes this Breakfast Egg Casserole So Special

For one, the chiles! It’s chile season I don’t mean soup.

During the peak season between August and September,  Hatch Green Chile Festivals take place all over! As these chiles reach their peak flavor and nutrient potential, stores often roast them outside, filling the air with a comforting aroma that reminds me of coming home in the fall. After all, who doesn’t love the smell of Chili that has been simmering on the stove all day or warm homemade bread? Luckily, this breakfast egg casserole fits right in with cooler weather go-to’s and meal prep staples. Not to mention, it smells so good you’ll want to wake up to it every morning!

More reasons to love this egg casserole:

  1. Not only is this green chile breakfast casserole easy to make ahead, but it’s also budget-friendly. 
  2. It’s adjustable for all your dietary needs! For all my vegetarian readers, this dish is perfect for those of you who are looking to add more protein to your diet and stabilize your blood sugar.
  3. It’s also the perfect recipe for holiday parties, busy school days, and everything in between!

My mouth is watering just thinking about it. So, let’s get on with the recipe so you can get to the store!

Ingredients for the Best Egg Casserole

Hatch Green Chile Pepper – Hatch green chiles add a slightly sweet and smoky flavor to this casserole, but if you don’t want to roast them or can’t find them in your store, you can just swap them out for chopped green chiles instead. 

Spinach – Spinach is a great source of vitamins A, C, K, folate, iron, and more. Plus, it adds color to this dish making it super pretty! 

Onions – For a sweet flavor, I recommend using white or yellow onions. Red onions have too much of a kick for this recipe. 

Eggs – Full of protein and healthy fats, eggs are the base of this recipe and hold the rest of the ingredients. If you want a slightly denser texture, you’ll want to add 1 or 2 extra before baking. 

Non-Dairy Milk – Milk helps create a creamy texture and adds tons of calcium to this dish. To keep this egg casserole allergy-friendly while still gaining nutritional benefits, I used almond milk, but any milk you keep on hand will work. 

Gluten Free Flour – If you don’t have arrowroot flour you can use potato starch or a gluten free multipurpose flour to create the same fluffy casserole effect without altering the flavor.

Chopped Green Chiles – Not only are they tasty, green chiles are rich in vitamin A, vitamin B6, calcium, zinc, and iron! I like to use a spicy version, but mild works, too. 

Cheese – For the best results, I recommend using unprocessed cheese that is also super meltable such as provolone, mozzarella, or white cheddar. However, if you follow a dairy free diet, simply omit the cheese or use a cheese alternative of choice. 

Tomato – Technically, the tomatoes are optional, but they add beautiful color to this recipe along with vitamins and antioxidants including vitamin C and potassium.

First Things First – How to Roast Hatch Green Chiles

You’ll want to roast your hatch green chiles before you add them to this casserole. To do so, start by heating your oven’s broiler, and line a baking sheet with foil. Then, place the whole chiles on the baking sheet, and let them roast for 3-4 minutes on each side or until their skin has browned. 

Don’t have time to roast chiles? No prob! See note below!

Pro Tip

Note:  Feel free to use any other pepper! Roasted red pepper and even poblano work great in this casserole.

To start, sauté the onion and spinach together on medium heat for about 3 minutes or until the onion is fragrant. 

Next, use an electric mixer to beat the eggs and milk in a large bowl until they are light and frothy. Then, add the flour, baking powder, and seasonings, and blend the ingredients until they are just combined. Add the green chiles, and mix them evenly. 

Layer the bottom of a casserole dish with the spinach and onion mixture followed by a few slices of cheese and egg batter. 

Pro Tip

Pro-Tip: For a thicker casserole use an 8×11’ dish. Or, if you like your casseroles on the thinner side, opt for a 9×13’ dish. 

Peel and slice the hatch green chile peppers, and layer them on top of the egg casserole along with tomato slices and more cheese. 

Place the dish in the oven to bake for 30-40 minutes letting it broil for the last minute to create crispy edges. 

Pro Tip

Note: Check the casserole after 30 minutes. If the outside is brown but the inside still hasn’t set, cover it with foil. Then, let it bake for another 5-10 minutes until the center has cooked.

Nutrition Tip

Nutrition Tip for Diet Variations:

  • Watching your cholesterol levels? Replace half of the eggs with an equivalent amount of egg whites.
  • Looking for more protein? Try adding in chicken sausage, shredded pork or chicken, or turkey bacon!
  • Need some added carbs to keep you fueled? Try pairing this casserole with roasted potatoes, or serve it in a gluten free tortilla for a breakfast burrito!

Common Questions

How do you keep egg casserole from falling?

It’s natural for the casserole to deflate a bit after it cooks. However, adding a bit more (1 tablespoon or so) of gluten free flour or starch will help! This should make the eggs “sturdier.”
Alternatively, you could try baking the casserole at a lower temperature for longer, around 325 F.

Why is my egg casserole rubbery?

If the casserole is rubbery, it is most often due to excess moisture from the veggies. To prevent this from happening, try patting the peppers and tomatoes with a paper towel or dishcloth before adding them to the casserole.

How do you know when an egg casserole is done?

You’ll know your egg casserole has finished baking when the edges are golden and a toothpick inserted in the center comes out clean.

What temperature should egg casserole be?

The internal temperature of your egg casserole should be between 180 and 190 degrees Fahrenheit (82-88° Celsius) before it has finished baking.

Meal Prep Tips

Once fully cooked, this green chile egg casserole will stay fresh in the fridge for up to 3 days. Or, store it in the freezer for up to 2 months. However, if you want to prepare it ahead of time and serve it fresh, you can easily prepare the egg batter the night before. Then, all you have to do is layer the veggies and cheese, and pop it in the oven! 

Reheating Tips

To avoid soggy leftovers, I recommend reheating your egg casserole in the oven at 350 degrees Fahrenheit. To keep it from drying out, try covering it with a piece of foil before placing it back in the oven.

Ingredients


Units

  • 2 hatch green chile pepper (see notes for substitutes)
  • 1 teaspoon olive oil or avocado oil
  • 1 cup baby spinach
  • 1 cup chopped white onion
  • 1012 eggs (12 eggs for a denser texture)
  • 1 cup non dairy milk
  • 3 Tablespoon arrowroot/tapioca flour or cornstarch
  • 1 teaspoon baking powder
  • 1/2 teaspoon salt
  • 1/4 teaspoon pepper
  • 1/2 teaspoon cumin

  • 6 ounces sliced cheese (parmesan, mozzarella, white cheddar)
  • 1 plum tomato, sliced
  • Grated hard cheese for topping (optional)
  • Fresh chopped cilantro

Instructions

  1. Preheat the broiler. Line a baking sheet with foil.
  2. Place the Hatch green chile pepper on the foil. Once the broiler is ready place the peppers in the oven, and broil them for 3-4 minutes on each side or until the skin is browned. Remove the peppers from the oven, and set them aside.
  3. Turn the oven temperature down to 350 degrees Fahrenheit.
  4. In a small pan, add 1 teaspoon of oil, and sauté the onion and spinach together on medium to medium high heat for about 3 minutes or until they are fragrant. Remove the pan from the heat.
  5. In a large bowl, beat the eggs and milk on medium-high speed with an electric mixer until they are light and fluffy. Add the flour (or starch), baking powder, salt, garlic powder, pepper, and cumin.
  6. Blend the ingredients for about 30 seconds until they are just combined and smooth. Stir in the canned green chilies (8 ounces).
  7. Layer the bottom of an 8×11 casserole dish with the cooked spinach and onion. (See notes for other sizes of dishes.)
  8. Then, add a few slices of cheese, followed by the egg and green chile batter.
  9. Once cooled, peel the skin off the roasted hatch green chiles and slice them length-wise, removing the stem. Layer the top of the casserole with tomato, slices, sliced roasted Hatch green chiles, and more cheese.
  10. Place the casserole in the oven, and bake for 30-40 minutes. Check the casserole after 30 minutes. If the outside is brown but the inside is still not set, cover the dish, and continue to bake for an additional 5 to 10 minutes. For crispy edges, set the oven to broil the last minute of cooking.
  11. Remove the casserole from the oven. Sprinkle it with extra cheese (if desired) and fresh cilantro. Salt and pepper to taste.

Notes

  • Feel free to use any other pepper! Roasted red pepper and even poblano work great in this casserole.
  • For a thicker casserole, use an 8X11 pan, or for a thinner casserole, use a 9×13 pan.
  • This egg casserole keeps well for 3 days covered in the fridge. The egg batter can be prepared the night before. Then, just layer with the vegetables and cheese before cooking.
