Step‑by‑Step Instructions for Chile Rellenos Casserole

Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This temperature is essential for achieving the perfect golden-brown top for your Chile Rellenos Casserole. As the oven warms up, you can prepare your baking dish and the rest of the ingredients, setting the stage for a delicious meal.

Step 2: Grease the Baking Dish
Lightly grease an 8×8 or 9×9 baking dish with non-stick spray or butter. This step helps prevent the casserole from sticking to the dish, ensuring easy removal once it’s baked. Spread the grease evenly across the bottom and sides to create a protective layer for your flavorful Chile Rellenos Casserole.

Step 3: Whisk the Wet Ingredients
In a mixing bowl, whisk together the eggs and whole milk until the mixture is completely smooth and well combined. This will create a rich and fluffy base for your casserole. Aim for a light froth on top as you whisk, which indicates that air is being incorporated, contributing to the overall texture once baked.

Step 4: Layer the Roasted Green Chiles
Evenly layer the roasted green chiles across the bottom of the prepared baking dish. Make sure to spread them out to ensure their smoky flavor permeates every bite of your Chile Rellenos Casserole. You can use fresh roasted chiles or canned fire-roasted chiles, depending on what you have on hand.

Step 5: Add the Cheese Blends
Sprinkle the Monterey Jack and cheddar cheese evenly over the chiles, covering them completely. The combination of these cheeses will melt beautifully, creating a creamy, bubbling layer that blends perfectly with the chiles. Ensure the cheese is distributed well for even flavor in every slice of your casserole.

Step 6: Pour the Egg Mixture
Gently pour the egg and milk mixture over the layered ingredients, ensuring it reaches all corners of the dish. This will bind the casserole together and create that signature fluffiness. Take care to pour slowly to avoid disturbing the layers of chiles and cheese too much, resulting in a structured dish.

Step 7: Bake Until Golden
Place the baking dish into the preheated oven and bake for 35 minutes. Keep an eye on the casserole as it bakes; the top should turn golden brown, and a toothpick inserted in the center should come out clean. This visually appealing finish indicates that the eggs are fully set and the cheese is melted to perfection.

Step 8: Cool Before Serving
Once baked, remove the casserole from the oven and let it cool for about 10 minutes. This resting time allows the flavors to meld and makes slicing easier. The Chile Rellenos Casserole will be hot and bubbly, so this final step ensures safe and enjoyable servings for everyone around the table.
