Chile Relleno Casserole Ingredients

For the Casserole
30 ounces mild green chiles – The main flavor base; feel free to use whole chiles or diced for easier distribution.
1 pound pepper jack cheese – Adds creaminess and a mild kick; freshly shredded melts better for that gooey texture.
1 pound cheddar colby jack cheese – Introduces a deep richness; opt for freshly shredded to elevate the flavor and consistency.
5-7 large eggs – Essential for structure and moisture, acting as the binding agent to hold everything together.
1 1/4 cups whole milk – Lends creaminess to the dish; almond milk can be used for a dairy-free alternative.
1 teaspoon coarse salt – Essential for enhancing overall flavors; adjust according to your taste preferences.
1 teaspoon powdered dry mustard – Adds a subtle depth of flavor; omit if you don’t have it on hand.
1/4 cup flour – Provides fluffiness and helps bind the egg mixture; skip it for a gluten-free version or try cream of tartar as a substitute.
Cooking spray – Prevents sticking and ensures easy serving.

Feel free to experiment with variations to make this Chile Relleno Casserole your own, and enjoy a delightful meal!

How to Make Chile Relleno Casserole

  1. Preheat the oven to 350°F. Prepare a 9×13 baking dish by spraying it generously with cooking spray to prevent sticking. This ensures your casserole comes out easily without any mess.
  2. Stuff the whole chiles with pepper jack cheese, or simply spread diced chiles evenly in the dish. Then, layer half the shredded cheddar colby jack cheese over the chiles for that creamy goodness.
  3. Whisk the eggs, whole milk, coarse salt, and dry mustard in a mixing bowl until the mixture is smooth and well combined. Pay attention to any lumps—they will affect the final texture.
  4. Combine a portion of the egg mixture with the flour to create a paste, and then mix it back into the main egg mixture. This step helps to bind everything together beautifully.
  5. Pour the egg mixture evenly over the chiles and cheese layers in the baking dish. It should cover them without leaving any dry spots—this will make for a cohesive casserole.
  6. Bake uncovered for 40 minutes. After that, sprinkle the remaining cheese on top and continue to bake for an additional 5 minutes, or until the cheese is melted and bubbly, and the casserole is firm.
  7. Cool the casserole for 5 minutes before serving. This brief resting time allows for easier slicing and helps the flavors to meld together perfectly.

Optional: Top with fresh cilantro or diced avocado for a pop of color and flavor!
