  • 3 (7 ounce) cans whole green chilies, fire roasted
  • 2 1/2 cups Monterey Jack cheese, shredded
  • 1 cup cheddar cheese, shredded
  • 6 large eggs
  • 1 3/4 cups milk (2% or whole)
  • 1/4 cup all-purpose flour
  • 1/2 teaspoon baking powder
  • 1/2 teaspoon salt
  • 1/4 teaspoon fresh ground black pepper
  • Pico de Gallo (optional)
  • Chopped cilantro (optional)
  • Sour cream (optional)


Step 1: Preheat the Oven

Preheat your oven to 350 degrees Fahrenheit. Spray a 9 x 13 inch dish with nonstick cooking spray.

Step 2: Prepare the Chilies

Cut the chilies open by slicing from top to bottom and remove any stems. Layer half of the cut chilies in the bottom of the prepared casserole dish.

Step 3: Add the Cheese

Sprinkle half of the Monterey Jack and cheddar cheese over the layer of chilies. Layer with the second half of the cut chilies and the remaining cheese.

Step 4: Make the Egg Mixture

In a medium bowl, whisk together the eggs, milk, flour, baking powder, salt, and black pepper. Pour the egg mixture over the cheese and green chilies.

Step 5: Bake

Bake for 35-40 minutes or until lightly browned on the edges and set in the middle.

Step 6: Cool and Serve

Cool for 7-10 minutes before slicing. Top with Pico de Gallo, chopped cilantro, and sour cream if desired.

Variations & Tips

Quality Ingredients

  • Cheese: For best results, buy good quality blocks of cheese and shred it yourself to avoid anti-caking agents that are often found in pre-shredded cheese.
  • Chilies: Canned green chilies can be found in the Hispanic food section of your local grocery store.

Add Protein

  • Ground Meat: Add 1 pound of cooked ground beef, ground chorizo, or ground pork sausage to the casserole with the two layers of cheese and green chilies.
  • Chicken: Increase the protein content by adding shredded chicken between the layers of chilies.

Enhance the Flavor

  • Fresh Peppers: Take this recipe to the next level by using fresh roasted poblano peppers instead of canned chilies.
  • Toppings: Customize with your family favorites like Pico de Gallo, sour cream, salsa, minced jalapeno, or chopped avocados.

Can I use fresh chilies instead of canned?

Yes, fresh roasted poblano peppers can be used instead of canned green chilies for a more authentic flavor.

How can I make this casserole spicier?

To add some heat, include minced jalapenos or a dash of hot sauce in the egg mixture. You can also use spicy cheese blends.

What type of milk works best for this recipe?

Whole milk or 2% milk works best, but you can also use half-and-half for a richer casserole. Avoid using skim milk as it may make the casserole less creamy.

Serve the casserole warm, topped with Pico de Gallo, chopped cilantro, and sour cream. It pairs well with a side salad, rice, or beans.

What if I don’t have a 9 x 13 inch dish?

How long can I store the leftovers?

Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. They can also be frozen for up to 2 months.

Can I add vegetables to the casserole?
