- 4 large eggs
- 1 cup whole milk (you can substitute with low-fat milk if preferred)
- ½ cup heavy cream (for that rich, creamy texture)
- ¼ cup all-purpose flour (sifted for a smoother mix)

- ¼ teaspoon black pepper (freshly ground is best)
- ¼ teaspoon garlic powder (for extra flavor)
- ¼ teaspoon onion powder (adds depth to the dish)
Step-by-Step Instructions
Preheat the Oven
-
First things first, preheat your oven to 350°F (175°C). This is crucial because you want that casserole to start cooking evenly right from the get-go!
Make the Egg Mixture
-
In a mixing bowl, whisk together the 4 large eggs, 1 cup of whole milk, and ½ cup of heavy cream. It should be a lovely, smooth mixture. Then, add in ¼ cup of all-purpose flour, ½ teaspoon of baking powder, ½ teaspoon of salt, ¼ teaspoon of black pepper, ¼ teaspoon of garlic powder, and ¼ teaspoon of onion powder. Keep whisking until everything is well combined. Don't worry if it looks a bit runny; that's perfectly normal!
Layer the Chiles and Cheese
-
Grab your baking dish and layer half of the drained and split open green chiles at the bottom. Spread them out evenly; it's all about that balance.
-
Now, sprinkle half of the 2 cups of shredded Monterey Jack or Pepper Jack cheese and 1 cup of shredded cheddar cheese over the chiles. Just look at that cheesy goodness! Repeat the layers with the remaining chiles and the rest of the cheese. You're creating a deliciously cheesy masterpiece here!
Pour and Bake
-
Pour the egg mixture evenly over the top of your layered chiles and cheese. Take your time with this step; you want to make sure every bit is coated and soaking in those flavors.
-
Finally, pop it in the oven and bake for about 30 minutes, or until it's set and golden. You'll know it's ready when your kitchen starts smelling heavenly, and you can't resist sneaking a peek!

Variations
- Add diced tomatoes or corn for a fresh twist.
- Try using roasted poblano peppers for a deeper flavor.
- Substitute with dairy-free cheese for a vegan version.
- Mix in cooked ground turkey or beef for added protein.
- Serve with a drizzle of salsa verde for a zesty kick.
