Ingredients

This simple yet flavorful baked poblano pepper casserole starts with fresh, quality ingredients.

You’ll need six medium poblano peppers, cooking spray or olive oil for greasing, 2 cups of shredded Monterey Jack cheese (divided), and 1 cup of shredded Colby Jack cheese (divided). For the rich custard, gather 5 large eggs, 1 ½ cups of whole milk, 3 tablespoons of all-purpose flour, 1 teaspoon of baking powder, ½ teaspoon of kosher salt, ½ teaspoon of garlic powder, ½ teaspoon of onion powder, ¼ teaspoon of dried oregano, and ¼ teaspoon of freshly ground black pepper. For serving, don’t forget fresh cilantro, sour cream, and roasted tomato salsa.

Notes & Substitutions

  • When crafting this cheesy baked pepper casserole, a few thoughtful substitutions can tailor it to your pantry or preferences. While fresh poblanos offer the best flavor, you can use two 7-ounce cans of whole green chiles, drained and patted dry, in a pinch.
  • For the cheese, feel free to experiment with authentic Mexican melting cheeses like Oaxaca or Chihuahua for a truly regional taste. If you need a dairy-free option, unsweetened almond milk or oat milk works well for the custard.
  • For gluten-free needs, a 1:1 gluten-free flour blend can easily replace all-purpose flour. Adjust the spices to your heart’s content, adding a pinch of cumin or a dash of cayenne if you desire extra warmth in your casserole bake.

  • Set your oven rack directly underneath the broiler and turn the broiler on high. Place the poblano peppers on a baking sheet lined with aluminum foil and broil for 5 minutes on each side until the skin is mostly blackened and blistered. This initial charring infuses a wonderful smoky flavor.
  • Remove the baking sheet from the oven and loosely cover it with aluminum foil or plastic wrap to trap in the heat. Allow the peppers to steam and the skin to soften for 5 minutes. This steaming process helps loosen the skins for easy peeling.
  • Peel, rub off, and discard as much of the loose skin as you can from each pepper. Make a vertical slit down one side of the peppers and remove and discard the stem, seeds, and veins. Set the prepared peppers aside.
  • Preheat the oven to 350°F and grease a 2-quart or 9×9-inch baking dish with cooking spray or olive oil.
  • Lay 3 of the roasted peppers on the bottom of the baking dish in a single, even layer. Sprinkle the top with 1 cup of Monterey Jack cheese and ½ cup of Colby Jack cheese. Repeat the layers with the remaining peppers and shredded cheese, building a foundation of flavor.
  • In a medium bowl, whisk together the eggs, milk, flour, baking powder, salt, garlic powder, onion powder, oregano, and black pepper until fully combined and smooth. This creates the rich, fluffy custard.
  • Pour the egg mixture evenly on top of the layered cheese and poblanos. Gently shake the dish to ensure the liquid settles into all the crevices.
  • Bake for 45 minutes until the casserole is beautifully puffed up in the center and the eggs are set and golden around the edges. A knife inserted into the center should come out clean.
  • Allow the baked casserole to cool and rest for 10 minutes before serving. This crucial resting time allows the custard to set completely, preventing it from collapsing. Garnish generously with fresh chopped cilantro and enjoy a comforting bite of this delightful Chile Rellenos Casserole Recipe.

Pro Tips & Troubleshooting

Cooking should be a joyful experience, not a source of frustration. A few simple insights can elevate your baked cheesy poblano dish from good to unforgettable, ensuring every batch is a success.

Common Mistakes to Avoid

  • Not Roasting Peppers Sufficiently: Under-roasted peppers will be tough to peel and lack the desired smoky depth. Ensure good charring on all sides.
  • Over-Mixing Egg Batter: Over-mixing can develop the gluten in the flour too much, leading to a dense, rather than fluffy, custard. Whisk just until combined.
  • Overbaking the Casserole: Baking for too long can result in a dry, rubbery texture. Keep an eye on it; it’s done when puffed and golden.
  • Slicing Too Soon After Baking: Cutting into the casserole immediately will cause it to deflate and the custard to spread. Patience is key for perfect slices.

Expert Tips for Success

  • Roast Peppers for Maximum Flavor: The char on the poblano skins develops a beautiful smoky sweetness, crucial for this dish. Don’t rush this step for the best-tasting poblano and cheese bake.
  • Thoroughly Steam Peppers for Easy Peeling: Steaming after roasting makes the skins effortlessly slide off, saving you time and frustration.
  • Use Freshly Shredded Cheese: Pre-shredded cheeses often contain anti-caking agents that can hinder smooth melting. Freshly shredded cheese melts beautifully and tastes better.
  • Adjust Seasonings to Taste: Taste the egg mixture before pouring it over the peppers and cheese. This allows you to fine-tune the salt and spices to your preference.
  • Let Casserole Rest for Best Texture: A 10-minute rest ensures the egg custard sets properly, giving you clean, stable slices of your comforting pepper and egg bake.

Serving Suggestions & Variations

This comforting baked Chile Rellenos Casserole Recipe is a star on its own, but it truly shines with a few thoughtful accompaniments. Serve each slice with a generous dollop of cool sour cream or a vibrant dollop of roasted tomato salsa. Slices of fresh avocado or a scoop of homemade guacamole add a creamy, fresh contrast. For a heartier meal, offer warm corn tortillas on the side or a bed of fluffy Mexican rice.

Flavor Variations

Get creative with your cheesy pepper and egg bake by adding your favorite ingredients.

  • Add Protein: Stir in cooked ground beef, spicy chorizo, shredded chicken, or tender pulled pork to make it a more substantial meal.
  • Vegetable Boost: Incorporate black beans, corn, sautéed spinach, or sliced mushrooms into the layers for extra texture and nutrients.
  • Spice It Up: For those who love a kick, finely diced jalapeños or serrano peppers can be added to the layers, or a dash of your favorite hot sauce to the egg mixture.

Frequently Asked Questions (FAQ)

Cooking is an adventure, and questions are a natural part of any journey. Here are some common queries about making your flavorful Chile Rellenos Casserole Recipe.

Can I use canned green chiles?

Yes, you can use two 7-ounce cans of whole green chiles, drained and patted very dry. Just note they won’t have the same smoky flavor as freshly roasted poblanos.

What if I don’t have a broiler?

You can roast the poblanos directly over a gas flame until charred, or bake them at 400°F (200°C) for 20-30 minutes, turning until skins are blackened.

Can I make this casserole ahead?

Absolutely! Assemble the casserole up to the point of baking, cover, and refrigerate overnight. Let it come to room temperature for 30 minutes before baking as directed.

How do I prevent a watery casserole?

Ensure your roasted poblanos are well-drained and patted dry before layering. Excess moisture from the peppers can lead to a watery result.

Is this recipe spicy?

Poblanos are generally mild, offering more flavor than heat. The spice level is quite gentle, making it family-friendly.
