How to Make Healthy Chicken Taco Casserole Recipe
Step 1: Preheat Your Oven and Prepare the Dish
Start by preheating your oven to 375 degrees Fahrenheit to get it ready for baking. Lightly grease a 9×13-inch baking dish—this ensures that the casserole won’t stick and will come out easily when it’s time to serve.
Step 2: Sauté the Vegetables
Heat the olive oil in a skillet over medium-high heat and toss in the minced garlic, diced yellow onion, and both red and green bell peppers. Let them cook together until everything softens and becomes fragrant, which should take about 5 minutes. This step deepens the flavors and softens the veggies just right for layering.
Step 3: Add the Black Beans and Taco Seasoning
Once your vegetables are tender, stir in the drained and rinsed black beans. Sprinkle the taco seasoning on top and mix it all until everything is evenly coated. This seasoning is the heart of the flavor, giving that classic taco taste you’re after. After mixing, remove the skillet from heat to keep things warm but not overcooked.
Step 4: Layer the Casserole
Now, the fun part: assembling the casserole. Start by placing 2 whole wheat tortillas flat in the bottom of your prepared baking dish. Over these, spread half of the bean and veggie mixture, then the shredded cooked chicken, followed by half the enchilada sauce and a generous sprinkling of cheese. Repeat all those layers with the remaining ingredients, finishing off with a heavy layer of cheese on the very top. This layering technique ensures each bite is packed with flavor and texture.
Step 5: Baking Time
Cover the casserole with foil and bake it for 15 minutes to allow everything to heat through nicely. Then remove the foil and bake uncovered for an extra 5 minutes. This step browns the cheese perfectly, giving you a bubbly, golden crust that makes it irresistible just to look at.
Step 6: Let It Cool and Garnish
Once out of the oven, give the casserole a few minutes to cool so it sets up and is easier to serve. Sprinkle the chopped green onions over the top for a fresh burst of color and flavor that just brightens the whole dish beautifully.
How to Serve Healthy Chicken Taco Casserole Recipe

Garnishes
While the chopped green onions add a fresh crunch, you can also jazz things up with some sliced avocado, a dollop of Greek yogurt or sour cream, and a sprinkle of fresh cilantro. Each garnish adds a layer of flavor and makes the dish look restaurant-worthy.
Side Dishes
For a complete meal, pair this casserole with simple sides like a crisp garden salad dressed in lime vinaigrette or a bowl of Mexican-style rice. These accompaniments keep things light and complement the robust flavors of the casserole perfectly.
Creative Ways to Present
If you want to impress, serve individual portions in small ramekins topped with a drizzle of hot sauce and a lime wedge on the side. Another fun idea is offering a build-your-own taco bar using the casserole as a filling, letting everyone customize their plate with their favorite toppings.
Make Ahead and Storage
Storing Leftovers
This Healthy Chicken Taco Casserole Recipe keeps wonderfully in the fridge for up to 3 days. Store leftovers tightly covered in an airtight container to preserve moisture and freshness, making it super easy to enjoy later without losing any flavor.
Freezing
If you want to prep in advance or save some for a busy day, you can freeze the assembled casserole (before baking). Wrap it tightly with foil and plastic wrap and freeze for up to 2 months. When you’re ready, just thaw overnight in the fridge and bake as usual.
Reheating
Reheat leftovers in the oven at 350 degrees Fahrenheit until heated through, about 15-20 minutes, or microwave individual portions for 2-3 minutes. Adding a little extra cheese on top before reheating can bring back that fresh-from-the-oven magic.
FAQs
Can I use other types of beans in this recipe?
Absolutely! If you don’t have black beans on hand, pinto or kidney beans will work just as well and still provide a great texture and taste for this casserole.
Is it possible to make this vegetarian?
For a vegetarian version of this Healthy Chicken Taco Casserole Recipe, simply omit the chicken and maybe add extra beans or even some sautéed mushrooms for an additional savory boost.
What’s the best way to shred cooked chicken?
The easiest way is to use two forks to pull the cooked chicken apart or toss it in a food processor with a few pulses for a quicker option without turning it into mush.
Can this recipe be made gluten-free?
Yes! To keep it gluten-free, use corn tortillas instead of whole wheat ones, and check that your taco seasoning and enchilada sauce don’t contain any hidden gluten ingredients.
How spicy is this casserole? Can I adjust it?
The heat level depends mostly on the taco seasoning and enchilada sauce you choose. Feel free to pick mild versions or add extra chili powder if you like it hotter—this recipe is very adaptable.
