Step‑by‑Step Instructions for Chile Relleno Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This step is crucial for ensuring that your Chile Relleno Casserole bakes evenly and achieves that delightful golden crust. Make sure the oven is fully heated before you place the casserole inside to get the best results.
Step 2: Prepare the Baking Dish
While the oven warms up, take a suitable baking dish and grease it generously with oil or butter. This will prevent your casserole from sticking and make for easier serving later. Use a paper towel or brush to spread the oil or butter across the entire surface of the dish.
Step 3: Layer the Green Chiles
Spread one cup of green chiles evenly on the bottom of your prepared baking dish. Feel free to use canned, frozen, or fresh chiles, depending on your preference. The chiles should cover the base completely, forming a flavorful foundation for your Chile Relleno Casserole that will soak up the delicious flavors.
Step 4: Add the Cheese
Next, sprinkle one cup of shredded cheese over the layer of green chiles. A blend of cheddar and Monterey Jack works beautifully, melting into gooey perfection. Make sure the cheese is distributed evenly, as it will create a luscious layer that combines wonderfully with the chiles during baking.
Step 5: Whisk the Egg Mixture
In a separate bowl, use a whisk to combine one cup of eggs, teaspoon each of salt and pepper, garlic powder, onion powder, and cumin. Whisk until the mixture is fully combined and slightly frothy. This will be the binding component of your Chile Relleno Casserole, adding taste and texture to the dish.
Step 6: Pour the Egg Mixture
Once your egg mixture is ready, pour it evenly over the layered cheese and chiles in the baking dish. Be gentle as you pour to avoid disturbing the layers below. This blend of eggs and spices creates a rich and fluffy texture that brings all the elements of the casserole together beautifully.
Step 7: Bake the Casserole
Place the baking dish in the preheated oven and bake for 30–35 minutes. Keep an eye on your casserole as it bakes; it’s ready when the edges are golden brown and a toothpick inserted in the center comes out clean. This perfect visual cue indicates that the casserole has set beautifully.
Step 8: Cool and Serve
Once baked, remove the Chile Relleno Casserole from the oven and let it cool slightly before serving. This resting period allows the flavors to meld and makes it easier to cut into portions. You’ll love the inviting aroma and the comforting appearance of this satisfying dish!
