Homemade Tomatillo Chicken Enchilada Casserole You’ll Want Every Week

Roasted Tomatillo Chicken Enchilada Casserole

This roasted tomatillo chicken enchilada casserole is the kind of dish that instantly becomes a regular in your kitchen. It combines tender shredded chicken, soft tortillas, melted cheese, and a bold homemade tomatillo sauce that brings everything together.

The highlight of this recipe is the roasted sauce, made from fresh tomatillos, garlic, and jalapeños. It delivers a tangy, slightly spicy flavour that takes this casserole far beyond the usual versions made with packaged sauces.

Why This Recipe Stands Out

What makes this casserole special is the homemade green sauce. Roasting the tomatillos and peppers creates a deeper flavour with a slightly smoky edge, while blending them with fresh herbs adds brightness.

The result is a sauce that is rich, vibrant, and perfectly balanced between tangy and creamy.

Key Ingredients

For the Sauce

• Tomatillos, husks removed
• Jalapeño peppers
• Garlic cloves
• Fresh cilantro
• Green onions
• Chicken or vegetable broth
• Sour cream
• Olive oil

For the Casserole

• Flour tortillas
• Boneless, skinless chicken breasts
• Shredded cheese

How to Make Roasted Tomatillo Sauce

Preheat the oven to 220°C (425°F). Place tomatillos and jalapeños on a baking tray and drizzle with oil. Wrap the garlic in foil with a little oil and place it on the tray.

Roast everything for about 30 minutes, turning once to prevent burning.

Transfer the roasted ingredients to a blender or food processor. Add cilantro and green onions, then blend until mostly smooth. Stir in broth, sour cream, and a bit of oil until the sauce reaches a slightly thick but pourable consistency.

Preparing the Chicken

Bring a pot of water to a boil, add the chicken, then turn off the heat and cover. Let it sit for about 30 minutes until fully cooked. Once done, shred the chicken and set aside.

Assembling the Casserole

Preheat the oven to 180°C (350°F) and lightly grease a baking dish.

Dip tortillas briefly in warm water to soften them. Layer the bottom of the dish with tortillas, followed by shredded chicken, sauce, and cheese.

Repeat the layers, finishing with a final layer of tortillas, sauce, and cheese on top.

Baking

Bake uncovered for 15 to 20 minutes until the casserole is hot, bubbly, and the cheese is melted.

Let it rest slightly before serving to allow the layers to set.

Tips for Best Results

• Adjust the amount of broth to control the thickness of the sauce
• Use freshly roasted ingredients for the best flavour
• Do not skip softening the tortillas to keep the texture tender
• Add extra toppings like fresh tomatoes or herbs for more color and freshness
