Chile Relleno Casserole with Eggs: A Southwestern Comfort

My grandmother, bless her heart, wasn’t much of a risk-taker in the kitchen, but she had a few dishes that were family staples. This Chile Relleno Casserole was one of them. I remember being a picky kid, but I’d always devour a huge piece, sneaking extra bites of the melted cheese off the top when no one was looking. The subtle heat of the chiles combined with the creamy, eggy custard was just pure comfort food, and the aroma would fill the whole house with warmth. It’s a dish that tastes of family gatherings, laughter, and love, and it’s one I cherish making to this day.

Recipe Overview

• Prep Time: 20 minutes
• Cook Time: 45 minutes
• Total Time: 1 hour 5 minutes
• Servings: 8
• Yield: 1 casserole
• Dietary Type: Vegetarian

Ingredients

• 4 (7 ounce) cans whole mild green chiles
• 1 lb Monterey Jack cheese
• 5 eggs
• 1 1/4 cups milk
• 1/4 cup flour
• 1/2 teaspoon salt
• 1 dash black pepper
• 4 cups grated cheddar cheese, mild (1 pound)

Equipment Needed

• 3-quart baking dish
• Mixing bowls
• Knife
• Whisk
• Measuring cups and spoons

Instructions

1. Preheat your oven to 350°F (175°C). Ensure that your oven rack is positioned in the center of the oven for even baking.
2. Prepare the green chiles: Gently slit each chile lengthwise along one side. Be careful not to tear the chile completely open. This slit allows you to remove the seeds.
3. Remove the seeds from each chile. This will reduce the overall heat of the dish, particularly important if you’re using anything beyond mild chiles. After seeding, drain the chiles well. Patting them dry with a paper towel can also help.
4. Slice the Monterey Jack cheese into ¼-inch thick slices. These slices will be used to stuff the chiles.
5. Stuff each chile with the sliced Monterey Jack cheese. Ensure a generous amount of cheese fills each chile, but don’t overstuff, as the cheese will melt and expand during baking.
6. Arrange the cheese-filled chiles in an ungreased 3-quart baking dish. Arrange them in a single layer, if possible, ensuring they are evenly distributed. This promotes even cooking and prevents overcrowding.
7. In a mixing bowl, whisk together the eggs, milk, flour, salt, and pepper. Whisk vigorously until the mixture is smooth and free of lumps. A smooth batter ensures an even distribution of flavor throughout the casserole.
8. Pour the egg mixture evenly over the stuffed chiles in the baking dish. Make sure all chiles are submerged in the mixture, which will create a custard-like consistency as it bakes.
9. Sprinkle the grated cheddar cheese evenly over the top of the casserole. The cheddar cheese will melt and create a golden-brown, bubbly crust.
10. Bake the casserole uncovered in the preheated oven for 45 minutes. The casserole is done when the top is golden brown and the egg mixture is set. A knife inserted into the center should come out clean.
11. Remove the casserole from the oven and let it cool slightly before serving. This will allow the casserole to set a bit more and make it easier to cut and serve.

Expert Tips & Tricks

• Spice it up!: If you prefer a spicier casserole, use hot green chiles or add a pinch of cayenne pepper to the egg mixture.
• Cheese variations: Feel free to experiment with different cheeses. Asadero, Oaxaca, or even pepper jack would be delicious alternatives.
• Make ahead: This casserole can be assembled ahead of time. Prepare it up to the point of baking, cover, and refrigerate for up to 24 hours. Add about 10 minutes to the baking time if baking directly from the refrigerator.
• Prevent a soggy bottom: Make sure to drain the chiles really well. You can even pat them dry with paper towels. A soggy casserole is nobody’s friend.
• Browning perfection: If the cheese is browning too quickly, you can tent the casserole with foil for the last 15 minutes of baking.

Serving & Storage Suggestions

Serve the Chile Relleno Casserole warm, cut into squares or wedges. It’s excellent on its own, but it’s also fantastic served with a side of sour cream, guacamole, or salsa. A dollop of Greek yogurt also makes a tangy and delicious topping.

Leftovers should be stored in an airtight container in the refrigerator. They will keep for 3-4 days. To reheat, microwave individual portions or reheat the entire casserole in a preheated oven at 350°F (175°C) until warmed through. You can also freeze the casserole for longer storage. Wrap tightly in plastic wrap and then in foil. It can be frozen for up to 2 months. Thaw overnight in the refrigerator before reheating.

Variations & Substitutions

• Dairy-Free: Use dairy-free cheese alternatives and a plant-based milk substitute like almond or oat milk. Be aware that the texture and flavor will be different.
• Gluten-Free: Ensure your flour is a gluten-free blend. A simple mix of rice flour, tapioca starch, and potato starch works well.
• Vegetarian with a Kick: Add some crumbled vegetarian chorizo or black beans for extra protein and flavor.
• Roasted Chiles: For a smoky flavor, roast fresh poblano peppers until blackened, then peel, seed, and use in place of the canned chiles.
• Different Cheeses: Try using a combination of Monterey Jack and pepper jack for a spicier kick, or Queso Oaxaca for a more authentic Mexican flavor.
• Add Vegetables: Incorporate sautéed onions, bell peppers, or corn for added flavor and texture.
