• 1/4 cup fresh cilantro chopped

For Assembly

• 1 cup shredded Colby Jack cheese or more Monterey Jack
• 4 large eggs
• 1/2 cup milk
• 1/4 cup all-purpose flour
• Pinch salt
• Optional toppings sour cream, extra cilantro, sliced avocado

Equipment

• Blender or food processor (optional, for smooth sauce)
• Cutting Board
• Knife
• Baking Sheet
• Tongs
• Plastic wrap
• Whisk

Method

 

Roast Poblanos

1. Preheat oven broiler. Place poblano peppers on a baking sheet. Broil for 5-7 minutes per side, turning with tongs, until skins are blistered and charred.
2. Transfer peppers to a bowl, cover tightly with plastic wrap, and let steam for 10-15 minutes. Once cooled, peel off the skins, remove stems and seeds, and slice the peppers into strips. Set aside.

Cook Chicken

1. While peppers cool, heat 1 tbsp olive oil in a large skillet over medium-high heat. Add cubed chicken seasoned with chili powder, cumin, garlic powder, salt, and pepper. Cook for 5-7 minutes, stirring occasionally, until chicken is cooked through and lightly browned. Remove from skillet and set aside.

Prepare Sauce

1. In the same skillet (no need to clean), heat 2 tbsp olive oil over medium heat. Add chopped yellow onion and cook for 5-7 minutes until softened and translucent. Add minced garlic and cook for 1 minute more until fragrant.
2. Stir in crushed tomatoes, chicken broth, oregano, cumin, salt, and pepper. Bring to a simmer, then reduce heat to low and let it cook gently for 10-15 minutes, allowing flavors to meld. Stir in fresh cilantro.

Prepare Egg Mixture

1. In a medium mixing bowl, whisk together eggs, milk, flour, and a pinch of salt until well combined and smooth. This will form the custard-like base.

Assemble Casserole

1. Preheat oven to 375°F (190°C). Lightly grease a 9×13 inch baking dish. Spread about 1/2 cup of the tomato sauce on the bottom of the baking dish. Arrange half of the roasted poblano strips over the sauce. Top with half of the cooked chicken. Sprinkle with 1.5 cups of the shredded cheese mixture (Monterey Jack and Colby Jack combined).
2. Pour about half of the egg mixture evenly over the cheese layer. Repeat the layers: remaining poblano strips, remaining chicken, and remaining shredded cheese (reserving about 1/2 cup for the very top).
3. Pour the remaining egg mixture over the layers. Gently pour the remaining tomato sauce evenly over the top. Sprinkle with the reserved 1/2 cup of shredded cheese.

Bake and Serve

1. Bake for 35-45 minutes, or until the casserole is bubbly, the cheese is melted and golden, and a knife inserted into the center comes out clean (indicating the egg mixture is set).
2. Remove from oven and let the casserole rest for 10-15 minutes before serving. This allows it to set properly and makes for easier slicing. Serve hot with optional toppings like sour cream, extra cilantro, or sliced avocado.

Notes

For extra heat, you can leave some seeds in the poblanos or add a pinch of cayenne pepper to the chicken seasoning. This casserole can be assembled ahead of time, covered, and refrigerated for up to 24 hours. If baking from cold, add about 10-15 minutes to the baking time. Leftovers store well in an airtight container in the refrigerator for up to 3-4 days.

Pro Tips for Making This chile relleno casserole with chicken

To ensure your chile relleno casserole with chicken turns out perfectly every time, I’ve gathered some of my go-to tips from years in the kitchen.

• Roast Your Poblanos Just Right: Don’t skip charring the poblanos! It enhances their smoky flavor and makes them easier to peel. My top tip is to place them in a bowl covered with plastic wrap immediately after roasting; the steam helps loosen the skin for effortless peeling.
• Don’t Overcook the Chicken: When cooking the boneless, skinless chicken breast, cook it just until it’s no longer pink. It will continue to cook in the oven, so slightly undercooking it initially prevents it from becoming dry.
• My Secret Trick: I always let my casserole rest for about 10-15 minutes after it comes out of the oven. This allows the layers to set beautifully, making for cleaner slices and preventing it from falling apart when serving.
• Cheesy Perfection: For the ultimate creamy texture in your chile relleno casserole with chicken, use freshly shredded Monterey Jack and Colby Jack cheese. Pre-shredded cheeses often contain anti-caking agents that can hinder their melt.

Fun Variations for chile relleno casserole with chicken

One of the greatest joys of home baking (and cooking!) is the freedom to get creative! This chile relleno casserole with chicken is wonderfully adaptable, and I love seeing how friends put their own spin on it.

Spice It Up

If you’re like my brother who loves a little extra kick, consider adding a finely diced jalapeño or serrano pepper to your onion and garlic mixture. You could also sprinkle a pinch of cayenne pepper into the sauce for a bolder flavor profile in your chile relleno casserole with chicken.

Veggie Boost

For an extra layer of goodness, my friend Sarah loves adding corn or black beans to her casserole. Simply stir a can of drained and rinsed corn or black beans into the chicken and sauce mixture before assembling. It adds lovely texture and boosts the fiber!

Different Cheeses

While Monterey Jack and Colby Jack are classic, feel free to experiment! A smoky gouda or a sharp cheddar could add a unique twist. My mom sometimes uses a blend that includes a little Oaxaca cheese for an even more authentic touch.

What to Serve With chile relleno casserole with chicken

This hearty chile relleno casserole with chicken is truly a meal in itself, but a few simple accompaniments can elevate it even further, making your dinner table feel extra special.

I love serving it with a simple, crisp green salad tossed with a light vinaigrette. The freshness cuts beautifully through the richness of the cheese and the peppers. A side of warm tortillas or a scoop of fluffy cilantro-lime rice would also be absolutely delightful for soaking up all those delicious flavors. My husband, always a fan of something cool and creamy, insists on a dollop of sour cream or a spoonful of fresh guacamole on the side. It’s truly comforting and makes for a complete, satisfying meal.

How to Store chile relleno casserole with chicken

Keeping your delicious chile relleno casserole with chicken fresh for future enjoyment is wonderfully simple, ensuring those comforting flavors last!

Refrigerator Storage

Once cooled to room temperature, cover the casserole dish tightly with plastic wrap or aluminum foil. It will keep beautifully in the refrigerator for up to 3-4 days. My personal tip is to press the plastic wrap directly onto the surface of the casserole to prevent any air from drying it out.

Freezing Instructions

If you’re looking to enjoy your chile relleno casserole with chicken even longer, it freezes well! After baking and allowing it to cool completely, cut the casserole into individual portions. Wrap each portion tightly in plastic wrap, then again in aluminum foil, and place them in an airtight freezer-safe bag or container. It can be frozen for up to 2-3 months.

Reheating Tips

To reheat, thaw frozen portions in the refrigerator overnight. For refrigerated leftovers, you can warm individual servings in the microwave or place the entire dish (covered with foil) in a preheated oven at 350°F (175°C) until heated through, about 20-30 minutes for a whole casserole.

Nutritional Benefits

While we always bake for joy and flavor, it’s lovely to know that this chile relleno casserole with chicken also offers some wonderful nutritional benefits. It’s packed with lean protein from the chicken, and the poblano peppers contribute vitamins and a touch of fiber. This makes it a treat that’s both incredibly satisfying and nourishing, embodying my philosophy of simple, wholesome ingredients.

FAQs

Can I make this chile relleno casserole with chicken ahead of time?

Absolutely! You can assemble the entire casserole, cover it, and refrigerate it for up to 24 hours before baking. Just add about 10-15 minutes to the baking time if baking from cold to ensure it’s heated through.

How can I adjust the spice level in this casserole?

To reduce the heat, remove the seeds and membranes from the poblano peppers entirely. For more spice, add a diced jalapeño to the onion mixture or a pinch of cayenne pepper to the sauce, transforming your chile relleno casserole with chicken.

What if I don’t have poblano peppers for my chile relleno casserole with chicken?

While poblanos are key for the authentic flavor, you could use roasted Anaheim peppers as a milder substitute. For a slightly different profile, green bell peppers could work, though they won’t offer the same smoky depth in your chile relleno casserole with chicken.

Can I freeze leftovers of this chile relleno casserole with chicken?

Yes, this casserole freezes beautifully! Allow it to cool completely, then wrap individual portions tightly in plastic wrap and foil. Store in a freezer-safe container for up to 2-3 months. Thaw in the refrigerator before reheating.
