Ingredients You’ll Need

Every ingredient here is pulling double duty: they create rich taste and deliciously hearty texture, while also bringing beautiful color and nutrients to your Healthy Chicken Taco Casserole. Gather these essentials, and you’ll see just how easy it is to make magic happen in a single casserole dish.

• Olive oil: Adds heart-healthy richness and keeps the veggies soft and flavorful.
• Garlic clove (minced): Just one clove brings a gentle, aromatic foundation to the casserole’s savory notes.
• Yellow onion (diced): Sweet and mild, it creates a classic base that soaks up every bit of spice.
• Red bell pepper (diced): Adds tangy sweetness and a pop of color to every bite.
• Green bell pepper (diced): Offers earthy crunch and balances the sweetness of red pepper beautifully.
• Black beans (15 ounces, canned, drained and rinsed): These hearty beans bring plant-based protein and a creamy texture.
• Taco seasoning (1 tablespoon): Provides that iconic zesty punch, making it unmistakably Mexican-inspired.
• Whole wheat tortillas (4, 8-inch): Earthy and hearty, they hold the layers together while sneaking in extra fiber.
• Cooked chicken (2 cups, shredded): Lean and versatile, shredded chicken soaks up all the flavors and adds satisfying protein.
• Low fat Mexican blend cheese (2 cups): Melted cheese unites each layer with creaminess without weighing it down.
• Enchilada sauce (1 cup): Whether homemade or store-bought, this brings a bold, tangy backbone to the casserole.
• Green onion (1/4 cup, chopped): Fresh, peppery, and the perfect finisher for a sprinkle of color and flavor.

How to Make Healthy Chicken Taco Casserole

Step 1: Prep the Oven and Baking Dish

Start by preheating your oven to 375 degrees Fahrenheit. Lightly grease a 9×13-inch baking dish—this step ensures that every slice of your Healthy Chicken Taco Casserole releases easily and stays picture-perfect.

Step 2: Sauté the Aromatics and Veggies

Heat olive oil in a large skillet over medium-high heat. Add the minced garlic first, letting it sizzle and bloom for about one minute. Then pile in the diced onion, red bell pepper, and green bell pepper, stirring for around five minutes until they’re soft and just starting to caramelize. The aroma will have your kitchen smelling like taco night already!

Step 3: Add Beans and Season

Toss your drained and rinsed black beans into the skillet, sprinkling in the taco seasoning for that signature kick. Stir everything gently so the beans are heated through and coated in those vibrant spices, then remove from heat. This savory mixture forms the backbone of your Healthy Chicken Taco Casserole.

Step 4: Layer the Casserole

Begin the layering by arranging two whole wheat tortillas at the bottom of your prepared baking dish. Spoon half of the bean and veggie mixture across the top, then scatter on half the cooked shredded chicken, half the enchilada sauce, and a generous handful of cheese. This step builds the structure and flavor layer by layer—don’t be shy with those ingredients!

Step 5: Repeat the Layers

Place the remaining two tortillas over the first layer and repeat: spread out the rest of your bean and veggie mixture, chicken, enchilada sauce, and finish with the remaining cheese. Make sure the top is thickly covered in cheese so it bakes up golden and bubbly.

Step 6: Bake to Perfection

Cover your Healthy Chicken Taco Casserole and bake it for 15 minutes. Then, uncover and return it to the oven for another 5 minutes to let the cheese turn irresistibly golden and slightly crisp at the edges. The aroma will make it tough to wait, but trust me—it’s worth it.

Step 7: Cool and Top

Remove the casserole from the oven and give it a few minutes to cool so the layers can set. Top with a scattering of fresh chopped green onion for a vibrant, zesty finishing touch—you’re now ready to serve!

How to Serve Healthy Chicken Taco Casserole

Garnishes

A finishing touch of freshness really takes things to the next level. Sliced avocado, a dollop of Greek yogurt (in place of sour cream), chopped cilantro, or a squeeze of fresh lime make each serving of Healthy Chicken Taco Casserole feel extra special and restaurant-worthy.

Side Dishes

While this casserole is hearty enough to stand alone, it pairs beautifully with a crisp side salad, cilantro-lime rice, or a bowl of roasted corn. For a lighter meal, try a tangy cabbage slaw that echoes those zesty taco flavors.

Creative Ways to Present

For a playful spin, you can serve Healthy Chicken Taco Casserole in individual ramekins at your next gathering, or cut it into small squares as a lively party appetizer. If you’re feeling adventurous, spoon warm casserole into lettuce cups for a hand-held, extra-fresh twist.

Make Ahead and Storage

Storing Leftovers

Any leftover Healthy Chicken Taco Casserole keeps well in the refrigerator for up to four days. Simply cover the dish tightly with foil or transfer slices to airtight containers to lock in all the flavor and moisture.

Freezing

This casserole is an absolute lifesaver when frozen. Cool the Healthy Chicken Taco Casserole fully, then cover tightly with a layer of plastic wrap and foil, or portion into lidded freezer-safe containers. It’ll stay fresh for up to three months—just be sure to label with the date so you never miss out.

Reheating

To reheat, thaw overnight in the fridge if frozen, then warm slices in the oven at 350 degrees until heated through (about 20 minutes). For a speedier option, the microwave works too—just add a small splash of water and cover loosely to keep things moist.

FAQs

Can I use rotisserie chicken instead of cooked chicken?

Absolutely! Rotisserie chicken makes this casserole even quicker to pull together and adds a tasty, savory depth. Just shred and use as directed.

Is there a way to make this casserole gluten-free?

Yes—swap out the whole wheat tortillas for your favorite certified gluten-free tortillas. Everything else in the Healthy Chicken Taco Casserole is naturally gluten-free, making this an easy adaptation.

What if I don’t like black beans?

Feel free to substitute with pinto beans, kidney beans, or even skip the beans entirely and bulk up the veggie content instead. This Healthy Chicken Taco Casserole is flexible and forgiving.

Can I assemble the casserole in advance?

Definitely! Assemble the Healthy Chicken Taco Casserole up to a day ahead, cover, and store in the fridge. When you’re ready to bake, just pop it in the oven and add a few extra minutes if needed.

How can I make it spicier?

Stir in some diced jalapeños when cooking the veggies, use a spicy enchilada sauce, or add red pepper flakes to the bean mixture. It’s easy to dial up the heat to suit your crowd.
