Casserole Ingredients

• Olive oil: 2 tablespoons for sautéing.
• Onion and bell pepper: 1 medium onion and 1 bell pepper, diced.
• Garlic: 3 cloves, minced.
• Black beans: 1 (15.5 oz) can, rinsed and drained.
• Sweet corn: 1 (15.25 oz) can, drained.
• Shredded chicken: 3 cups (rotisserie or homemade).
• Green chilis: 1 (4 oz) can or 1–2 fresh chilis, chopped; add to taste.
• Salt and pepper: 1/2 teaspoon salt and 1/4 teaspoon cracked black pepper.
• Taco seasoning: 2 tablespoons.
• Enchilada sauce: 2 cups total (reserve 1/2 cup for the baking dish).
• Flour tortillas: 6 medium to large.
• Cheese: 1 cup shredded white cheddar and 1 cup shredded regular cheddar (or 2 cups of one type).
• Garnishes: chopped cilantro, sliced avocado, sour cream, etc.

How to Make Chicken Enchilada Casserole

1. Preheat: Heat the oven to 350°F.
2. Sauté aromatics: Warm the oil in a large skillet over medium heat. Add diced onion and bell pepper and cook until softened, about 5 minutes. Add garlic and cook 1 minute more.
3. Add filling: Stir in black beans, corn, shredded chicken and green chilis. Season with salt, pepper and taco seasoning. Cook until everything is heated through, about 5 minutes.
4. Add sauce: Reserve 1/2 cup of enchilada sauce for the dish bottom. Pour the remaining enchilada sauce into the skillet and mix with the filling.
5. Assemble: Spread the reserved 1/2 cup of enchilada sauce on the bottom of a 9×13-inch baking dish. Place two tortillas to cover the bottom. Spoon one-third of the chicken mixture over the tortillas, then sprinkle with one-third of the cheese. Repeat the tortilla, filling and cheese layers two more times, finishing with cheese on top.
6. Bake: Bake for 30 minutes, until the casserole is bubbly and the cheese is melted.
7. Serve: Let the casserole rest for 8–10 minutes before cutting. Serve with sour cream, sliced avocado and chopped cilantro.

Tips for Success

• Corn tortillas: If using corn tortillas, briefly sauté them in hot oil before layering to reduce sogginess.
• Don’t overcook: Use precooked chicken and warm it just until heated so it stays moist.
• Let it rest: Allow the casserole to sit 8–10 minutes after baking so it sets and slices cleanly.

Variation & Mix-In Ideas

• Beef: Substitute shredded beef or cooked ground beef for a different flavor.
• Green sauce: Use green enchilada sauce instead of red for a fresh twist.
• Extra toppings: Add sautéed mushrooms, diced tomatoes, black olives or other taco-bar favorites to customize the casserole.

What Goes with Enchilada Casserole?

• Refreshing drinks: A bright, citrusy beverage pairs nicely with the rich casserole.
• Salsa: Fresh salsa or an avocado-based salsa helps cut the richness of the sauce and cheese.
• Simple dessert: A light, easy dessert finishes the meal without extra fuss.

How to Store and Reheat Leftovers

• Refrigerate: Cover tightly and refrigerate for up to 3 days.
• Reheat: Warm in a 350°F oven for about 20 minutes, or until heated through.

Can I Freeze Chicken Enchilada Casserole?

• Freeze before baking: Assemble but do not bake. Cool, cover tightly with foil and plastic wrap, and freeze up to 3 months.
• To cook from frozen: Bake as directed, adding 5–15 minutes as needed until heated through.
