Healthy Chicken Taco Casserole is a delicious and comforting dish that brings together tender shredded chicken, vibrant veggies, and just the right amount of spice. It’s layered with beans, cheese, and a mix of flavorful taco seasonings, all baked to bubbly perfection. This casserole has the familiar taste of tacos but in a warm, cozy form that’s perfect for family dinners.
I love making this casserole because it feels like a treat without the heavy guilt. Using lean chicken and plenty of veggies means you get all the goodness without extra calories. Plus, it’s a one-dish meal, which means less mess and more time to relax or chat with family while it’s baking in the oven.
My favorite way to serve it is with a dollop of plain Greek yogurt and a sprinkle of fresh cilantro on top. It adds a cool and fresh contrast that really kicks the taco flavors up a notch. This casserole is great for feeding a crowd or making ahead for easy weeknight dinners. It’s one of those dishes that gets better the next day, too, so leftovers are always a win!
Key Ingredients & Substitutions
Chicken breast: Using skinless, lean chicken breast keeps the casserole light and healthy. You can swap it with shredded rotisserie chicken or cooked turkey for convenience or variety.
Brown rice: This adds fiber and a nutty flavor, improving the dish’s nutrition. If you prefer, use quinoa or cauliflower rice for a lower-carb option.
Black beans & corn: These boost the protein and fiber, giving great texture and flavor. If black beans aren’t available, pinto or kidney beans work well. Fresh or frozen corn are both good choices.
Cheese: Reduced-fat cheddar cheese adds tasty meltiness with fewer calories. You can try a Mexican cheese blend or a lighter mozzarella if you want a milder taste.
Taco seasoning: Store-bought packets are easy, but making your own lets you control salt and spice levels. Adjust chili powder and cumin to suit your taste.
How Can I Make This Casserole Moist and Flavorful Without Extra Fat?
Keeping the casserole moist while staying healthy can be tricky. Here’s how I do it:
- Sauté onion and bell pepper in a small amount of olive oil to bring out their natural sweetness and soften them without needing extra fat.
- Add diced tomatoes with green chilies to introduce a juicy, tangy element that moistens the mix.
- Use shredded chicken that’s cooked but not dried out; if using leftovers, reheat gently before combining.
- Mix all ingredients thoroughly to ensure every bite is flavorful and moist.
- Don’t overbake—the cheese should melt and be bubbly, but not dry out; 20-25 minutes usually works perfectly.
Equipment You’ll Need
- 9×9 inch baking dish – I like it because it’s the perfect size to hold all the layers without spilling over.
- Large skillet – makes sautéing the veggies and mixing everything easy and quick.
- Wooden spoon or spatula – helps stir ingredients evenly without scratching your pan.
- Measuring cups and spoons – keep everything precise for the best results.
- Oven – needed to bake the casserole until golden and bubbly.
Flavor Variations & Add-Ins
- Swap chicken for cooked ground turkey or beef; it adds a different flavor and texture.
- Mix in some chopped jalapeños or a dash of hot sauce if you like extra spice.
- Add diced avocado or a squeeze of lime on top for a fresh, creamy contrast.
- Stir in chopped spinach or kale with the veggies for more greens and nutrition.

- 1 1/2 cups reduced-fat shredded cheddar cheese

How Much Time Will You Need?
Preparation takes about 10 minutes to chop and sauté vegetables and mix the ingredients. Baking takes 20-25 minutes, and then a 5-minute rest before serving. In total, plan for about 35-40 minutes from start to table.
Step-by-Step Instructions:
1. Prepare and Sauté Vegetables:
Preheat your oven to 375°F (190°C). Lightly grease a 9×9 inch casserole dish. In a large skillet over medium heat, warm 1 teaspoon of olive oil. Add the diced onion and green bell pepper and cook until they soften, about 4-5 minutes.
2. Combine the Filling Ingredients:
Add shredded chicken, cooked brown rice, black beans, corn kernels, and drained diced tomatoes with green chilies into the skillet. Sprinkle the taco seasoning over the mixture. Stir everything well and cook for another 2-3 minutes to let the flavors come together.
3. Assemble the Casserole:
Spread half of the chicken and rice mixture evenly into your prepared casserole dish. Sprinkle half of the reduced-fat shredded cheddar cheese and half the sliced black olives over the first layer. Add the remaining chicken mixture on top, then finish by sprinkling the rest of the cheese and olives evenly over the casserole.
4. Bake and Serve:
Place the uncovered casserole in the preheated oven and bake for 20-25 minutes, or until the cheese is melted and bubbly. When done, remove it from the oven and let it rest for 5 minutes. Serve warm, garnished with chopped fresh tomato, cilantro, and a dollop of Greek yogurt if you like.
Can I Use Frozen Chicken for This Casserole?
Yes! Just be sure to fully thaw the chicken in the refrigerator overnight before shredding and using it in the recipe. This helps keep the texture tender and avoids excess moisture.
Can I Make This Casserole Ahead of Time?
Absolutely! Prepare and assemble the casserole, then cover and refrigerate it for up to 24 hours before baking. When ready, bake as directed, adding a few extra minutes if baking straight from the fridge.
How Should I Store Leftovers?
Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently in the microwave or oven until warmed through.
Can I Substitute the Brown Rice with Something Else?
Yes, you can swap brown rice for quinoa, cauliflower rice, or even whole wheat pasta if you prefer. Just cook the substitute fully before adding it to the casserole.
