Why I Love This Recipe
This recipe is quick to prepare and a total crowd-pleaser.
I love that I can use leftover rotisserie chicken and toss in any extra veggies I have on hand.
The layers come together easily, and the final result is a golden, bubbly casserole that tastes like comfort in every bite.
What You’ll Need (Ingredient Highlights)
Shredded chicken: Perfect for using up leftovers or rotisserie chicken.
Black beans: Adds plant-based protein and hearty texture.
Bell peppers and onion: Bring natural sweetness and color.
Whole wheat tortillas: A wholesome base that holds everything together.
Enchilada sauce: Adds moisture and bold flavor—store-bought or homemade.
Mexican blend cheese: Melty, cheesy goodness in every layer.
Pro Tips Before You Start
For extra depth, lightly toast the tortillas before layering.
Want a bit of heat? Add chopped jalapeños or a dash of hot sauce to the bean mixture.
Let the casserole rest for 5–10 minutes before slicing so it holds its shape better.
How to Make Cheesy Chicken Enchilada Casserole
Step 1: Prep the Oven
Preheat your oven to 375°F (190°C) and grease a 9×13-inch baking dish with cooking spray or oil.
Step 2: Sauté the Veggies
Heat olive oil in a skillet over medium-high heat.
Add minced garlic and cook for about 1 minute, then toss in the diced onion and bell peppers.
Sauté until soft—about 5 minutes.
Step 3: Add Beans and Seasoning
Stir in the black beans and taco seasoning.
Mix well to heat everything through, then remove from heat.
Step 4: Start Layering
Place two whole wheat tortillas on the bottom of your baking dish.
Add half the veggie-bean mixture, half the shredded chicken, half the enchilada sauce, and half the cheese.
Step 5: Repeat
Add two more tortillas and repeat the layers.
Finish with a generous layer of shredded cheese on top.
Step 6: Bake
Cover the dish with foil and bake for 15 minutes.
Then uncover and bake for another 5 minutes until the top is golden and bubbly.
Step 7: Garnish and Serve
Let the casserole cool for a few minutes, then sprinkle with chopped green onions.
Slice and enjoy!
