Ingredients You’ll Need

This Healthy Chicken Taco Casserole brings together simple staples for a meal that’s fresh, colorful, and supremely satisfying. Each ingredient is either a flavor booster, a wholesome base, or a melty topping—think of them as the dream team for a cozy, nutritious dinner!

• Olive oil: Essential for sautéing the vegetables, and adds a subtle richness without overpowering the other flavors.
• Garlic clove, minced: Just one, but it brings in that irresistible savory base note.
• Yellow onion, diced: Sautéed onion builds a sweet, fragrant backbone for your filling.
• Red and green bell peppers, diced: Both peppers add beautiful color and a gentle crunch, making every bite more interesting.
• Black beans (15 ounces, drained and rinsed): These make the casserole filling and give plenty of plant-based protein and fiber.
• Taco seasoning: The spice heart of the dish—choose a homemade blend or your favorite store-bought packet for flavor with zero hassle.
• Whole wheat tortillas (4, 8”): The lighter, fiber-rich foundation for every delicious layer.
• Cooked chicken, shredded (2 cups): Using pre-cooked rotisserie or weekend meal-prep chicken makes assembly a breeze.
• Low fat Mexican blend cheese (2 cups): Melts beautifully, giving you that irresistible gooey top while keeping things light.
• Enchilada sauce (1 cup): Store-bought or homemade, this brings zesty moisture and authentic Southwest flavor to every layer.
• Green onion, chopped (¼ cup): Sprinkled over top, it adds a fresh, peppery finish to the casserole.

Variations

One of my favorite things about this Healthy Chicken Taco Casserole is that it’s wonderfully forgiving—making it a blank canvas if you like to tweak things for flavor, nutrition, or dietary needs. Here are a few fun ways to put your signature spin on this recipe!

• Vegetarian-friendly: Skip the chicken and double the black beans, or swap in lentils for a hearty meatless casserole.
• Go spicy: Add extra chopped jalapeños or a few dashes of hot sauce to the vegetable sauté for a fiery kick.
• Dairy-free: Use your favorite plant-based cheese, or simply top with a generous sprinkle of nutritional yeast for cheesy flavor without dairy.
• Low-carb: Substitute low-carb tortillas or thin zucchini slices for a lighter, grain-free take.

How to Make Healthy Chicken Taco Casserole

Step 1: Prepare Your Oven and Dish

Preheat your oven to 375°F (190°C) to guarantee that golden-bubbly finish. Lightly grease a 9×13 baking dish—this not only helps with cleanup but also prevents sticking, so every cheesy slice lifts out easily.

Step 2: Sauté the Veggies

Warm the olive oil in a large skillet over medium-high heat. Toss in the minced garlic and let it sizzle for about a minute, then add the diced onion and both bell peppers. Cook everything for around 5 minutes until your kitchen smells amazing and the veggies are softened with just a hint of caramelization.

Step 3: Build the Taco Filling

Add the drained black beans and sprinkle in the taco seasoning. Give everything a toss so the spices coat every ingredient and the beans are just warmed through. Take the skillet off the heat—your filling is ready!

Step 4: Layer It Up

Lining your baking dish with two tortillas, tear or overlap them as needed to cover the bottom. Spoon in half the bean mixture, then scatter half the shredded chicken over it. Drizzle generously with enchilada sauce and sprinkle on half the cheese—try to layer evenly for the perfect flavor in every bite. Repeat with a second layer, finishing with a thick blanket of cheese on top.

Step 5: Bake to Golden Perfection

Cover the casserole with foil and bake for 15 minutes to let everything meld together. Then, remove the cover and bake for an additional 5 minutes—watch for that glorious golden, bubbly cheese that signals it’s ready to eat! Let it cool slightly, then shower with chopped green onions before serving.

How to Serve Healthy Chicken Taco Casserole

Garnishes

For a fiesta of flavor and color, sprinkle your Healthy Chicken Taco Casserole with thinly sliced green onions, fresh chopped cilantro, or even a few diced cherry tomatoes. A dollop of Greek yogurt (or light sour cream) and some avocado slices take every serving completely over the top!

Side Dishes

This casserole is hearty on its own, but it pairs perfectly with simple sides like a crisp green salad, roasted corn, or even a bowl of cilantro-lime brown rice. For a fun touch, add a dish of salsa or extra enchilada sauce for drizzling at the table.

Creative Ways to Present

Slice your Healthy Chicken Taco Casserole cleanly and plate each generous wedge on a colorful dish. For parties, try baking in individual ramekins for personal casseroles, or serve as hearty taco “squares” in cupcake liners for easy picking at tailgates and potlucks!

Make Ahead and Storage

Storing Leftovers

Cover any leftover casserole tightly or transfer to an airtight container, and store it in the fridge for up to 3 days. It’s just as good, if not better, the next day as the flavors deepen together—making lunch or dinner extra delicious with minimal effort.

Freezing

Want to prep ahead or save some for later? Healthy Chicken Taco Casserole freezes beautifully! Wrap cooled portions tightly in foil and then plastic wrap, or place in freezer-safe containers for up to 2 months. Thaw overnight in the fridge before reheating.

Reheating

For best results, reheat leftovers in a 350°F oven, covered, until warmed through (about 20–25 minutes), then uncover for a few extra minutes to crisp up the top. Microwave individual servings for 1–2 minutes, but watch for hot spots—in both cases, a sprinkle of fresh green onion after reheating brightens up each bite!
