This Healthy Chicken Taco Casserole is a perfect mix of comforting and good-for-you. It’s packed with tender shredded chicken, black beans, corn, and just the right amount of spices to give it that classic taco flavor without feeling heavy. The layers of cheese on top melt beautifully, adding a little gooey goodness that everyone loves.
I love making this casserole when I want something that feels like a treat but is still wholesome. It’s super easy to put together, and I usually toss in extra veggies like bell peppers or tomatoes to add some freshness. What’s great is that it reheats well, so you can enjoy leftovers for a quick lunch or dinner the next day.
My favorite way to serve it is right out of the casserole dish with a scoop of plain yogurt or sour cream, a sprinkle of fresh cilantro, and maybe some avocado slices on the side. It’s a dish that brings a cozy, family-friendly vibe to the table every time!
Key Ingredients & Substitutions
Chicken: Shredded cooked chicken works best for this casserole. Rotisserie chicken saves time, but boiled chicken breast is leaner and just as good.
Brown Rice: Brown rice adds fiber and a nice nutty flavor. If you’re short on time, cooked quinoa or cauliflower rice are good low-carb alternatives.
Black Beans & Corn: These boost protein and fiber while keeping things colorful. Canned beans need to be rinsed well to remove excess salt. Frozen corn is fine if fresh isn’t available.
Taco Seasoning: Store-bought packets are convenient but watch the salt content. Making your own blend lets you control spices and avoid preservatives.
Cheese: Reduced-fat cheddar and Monterey Jack keep the dish lighter but still melty and flavorful. You can swap for part-skim mozzarella for a milder melt.
Greek Yogurt: This adds creaminess without extra fat compared to sour cream. If you’re dairy-free, try a plant-based yogurt or skip it altogether.
How Do You Get the Perfect Flavor Blend in the Casserole?
The key is in layering flavors and textures:
- Sauté the onions and garlic first until soft. This builds a savory base.
- Mix chicken, beans, corn, and seasoning with the rice and tomatoes to combine all tastes well.
- Don’t skip stirring in the Greek yogurt to add a creamy, tangy kick that balances spices.
- Fresh cilantro and diced tomato garnish added after baking brighten up the casserole with fresh notes.
- Give it a few minutes to rest after baking so the casserole sets and slices cleanly.
Following these steps ensures each bite has a nice balance of warmth, creaminess, herbs, and spice.
Equipment You’ll Need
- 9×9 inch baking dish – I like it because it’s the perfect size for this casserole, managing even baking.
- Large skillet – makes sautéing the onions and garlic easy and keeps everything in one pan before baking.
- Chef’s knife and cutting board – for chopping cilantro, tomatoes, and onion easily.
- Measuring cups and spoons – help you get the right amount of ingredients.
- Grater – for shredding cheese fresh, if you prefer it to pre-shredded.
Flavor Variations & Add-Ins
- Use cooked lean ground turkey or beef instead of chicken for a different flavor profile.
- Swap cheddar and Monterey Jack with pepper jack or a Mexican blend for extra spice.
- Add sautéed bell peppers, zucchini, or corn for even more veggies and crunch.
- Mix in a dash of hot sauce or chopped jalapeños if you like extra heat.

Ingredients You’ll Need:
- 2 cups cooked chicken, shredded (rotisserie or boiled)
- 1 cup cooked brown rice
- 1 can (15 oz) black beans, drained and rinsed
- 1 cup corn kernels (fresh or frozen)
- 1 can (10 oz) diced tomatoes with green chilies, drained
- 1 packet (1 oz) taco seasoning (or homemade: chili powder, cumin, garlic powder, paprika, salt)
- 1 cup shredded reduced-fat cheddar cheese
- 1 cup shredded reduced-fat Monterey Jack cheese
- 1/2 cup plain Greek yogurt (optional, for creaminess)

- 2 cloves garlic, minced
- 1/4 cup fresh cilantro, chopped (plus extra for garnish)

How Much Time Will You Need?
This casserole takes about 15 minutes to prep and 20-25 minutes to bake, plus 5 minutes to rest before serving. So about 40-45 minutes total from start to finish.
Step-by-Step Instructions:
1. Preheat and Prepare:
Preheat your oven to 375°F (190°C). Lightly grease a 9×9 inch baking dish with cooking spray or olive oil so the casserole doesn’t stick.
2. Sauté Onions and Garlic:
Heat olive oil in a large skillet over medium heat. Add chopped onion and minced garlic. Cook, stirring often, until they soften and smell delicious—about 3 to 4 minutes.
3. Mix the Chicken Filling:
Add shredded chicken, taco seasoning, black beans, corn, cooked brown rice, diced tomatoes with green chilies, and Greek yogurt to the skillet. Stir everything well to blend all the flavors. Then, take it off the heat and stir in half of the chopped cilantro.
4. Assemble the Casserole:
Pour the filling evenly into your prepared baking dish. Sprinkle the shredded cheddar and Monterey Jack cheeses evenly on top so they melt beautifully and make a cheesy crust.
5. Bake Time:
Bake the casserole uncovered for 20-25 minutes or until the cheese is melted, bubbly, and golden around the edges.
6. Rest and Garnish:
Take the casserole out of the oven and let it rest for 5 minutes; this helps it set so it slices nicely. Sprinkle with the remaining chopped cilantro and fresh diced tomatoes for a pop of color and freshness.
7. Serve and Enjoy:
Enjoy your warm, comforting chewy casserole as is, or add a dollop of plain Greek yogurt or sour cream for extra creaminess. This dish is perfect for a healthy family dinner or meal prep for the week!
Can I Use Frozen Chicken in This Recipe?
Yes! Just make sure the chicken is fully thawed before shredding. Thaw it overnight in the fridge or use the defrost setting on your microwave. Pat it dry to avoid extra moisture in the casserole.
Can I Make This Casserole Ahead of Time?
Absolutely! Prepare the mixture and assemble the casserole, then cover and refrigerate for up to 24 hours before baking. Add a few extra minutes to the baking time if baking straight from the fridge.
How Should I Store Leftovers?
Store leftovers in an airtight container in the fridge for up to 3 days. Reheat gently in the microwave or oven until warmed through. You can also freeze portions for up to 2 months—thaw overnight before reheating.
Can I Substitute Brown Rice with Another Grain?
Yes! Quinoa, cauliflower rice, or even cooked whole wheat couscous are great substitutes and keep this dish healthy and filling. Just make sure your chosen grain is fully cooked before adding it to the casserole.
