Simply put, Chile Relleno Casserole works because it takes the essence of a traditional dish and reimagines it in a way that’s approachable, delicious, and reliable every time.
What You’ll Need For This Recipe
To make a rich and flavorful Chile Relleno Casserole, gather the following ingredients:
Whole Green Chiles (14 ounces, canned): These are mild, roasted chiles packed in brine. They’re the foundation of the dish and provide a smoky, peppery backdrop without overwhelming heat.
Jack Cheese (3/4 pound, grated): Known for its creamy, melty quality, jack cheese ensures gooey goodness in every bite.
Cheddar Cheese (1 cup, grated): Adds sharpness and a deeper flavor profile, balancing the milder jack cheese.
Eggs (2 large): They give the casserole structure and help bind the filling.
All-Purpose Flour (1/2 cup): Provides a slight thickness to the custard mixture, ensuring the casserole sets properly.
Milk (1½ cups): Creates a smooth custard that bakes into a light, creamy base.
Salt (1 teaspoon): Essential for flavor balance.
Black Pepper (1/2 teaspoon): Adds just the right amount of seasoning and mild heat.
Optional add-ins include cooked ground beef, shredded chicken, diced onions, or even a sprinkle of fresh cilantro after baking.
How To Make Chile Relleno Casserole
Here’s a step-by-step breakdown of how to prepare Chile Relleno Casserole:
Prepare the Pan: Preheat your oven to 350°F and spray a 9×9 inch baking dish with nonstick spray. This ensures easy removal and prevents sticking.
Prepare the Chiles: Slice the whole canned green chiles open, rinse out any seeds, and drain them well. This step keeps the casserole from becoming watery.
Layer the Ingredients: Arrange half the chiles in the bottom of the dish, followed by half the grated jack and cheddar cheeses. Add another layer of chiles, then top with the remaining cheese.
Make the Custard Mixture: In a small bowl, whisk together the eggs, flour, milk, salt, and pepper until smooth. Pour this mixture evenly over the casserole.
Bake: Place the dish in the oven, uncovered, and bake for 30–35 minutes, until the top is golden brown and the casserole is set.
Cool & Slice: Allow the casserole to cool for a few minutes before slicing into six equal pieces. Serve warm and enjoy the cheesy, peppery goodness.
Tips + Tricks & More For Recipe Success
To ensure your Chile Relleno Casserole turns out perfectly every time, here are some expert tips:
Drain Chiles Thoroughly: Excess liquid from canned chiles can make the casserole watery. Pat them dry with paper towels if necessary.
Shred Your Own Cheese: Pre-shredded cheese often contains anti-caking agents that prevent smooth melting. For best results, grate block cheese yourself.
Custard Consistency: Whisk the flour well into the milk and eggs to avoid lumps. A smooth mixture bakes into a custard-like texture.
Spice Level: If you prefer more heat, swap the canned green chiles for fire-roasted Hatch chiles or add diced jalapeños.
Make Ahead: Assemble the casserole up to one day in advance, cover, and refrigerate. Bake when ready to serve.
Double the Recipe: For larger gatherings, double the ingredients and bake in a 9×13 dish. Increase baking time by 10–15 minutes.
Storage: Leftovers keep well in the refrigerator for up to 3 days. Reheat gently in the oven or microwave.
By following these tricks, your Chile Relleno Casserole will consistently come out golden, flavorful, and perfectly set.
