Your favorite taco flavors in an easy-to-prepare casserole!

Need an easy-to-prepare dinner that the entire family will enjoy? Look no further because you’ve found it! This Mexican-inspired, healthy chicken taco casserole is stacked with healthy, protein-rich ingredients that even the kids will love. It offers all of the classic flavors you crave in a simple-to-serve casserole. And the leftovers taste pretty amazing, too—in the unlikely chance that you end up with any!
For the Love of Casseroles

Growing up, my mom’s go-to dinners were almost always based around some sort of casserole. Since then, I’ve always been inspired to put my favorite dishes and flavors together to create unique and delicious casseroles just like this one! We’ve combined amazing Mexican flavors using healthy ingredients and simple taco spices (and you can even make our very own Enchilada Sauce) in this stacked casserole.
The Skinny On This Dish

We’ve swapped out some of the traditional, higher-fat ingredients in this recipe for some low-fat ones. This includes choosing shredded chicken over any ground beef, as well as low-fat cheese and black beans (no refried beans in here!) We’ve also used fiber-rich whole wheat tortillas and colorful veggies to fill out this healthy chicken taco casserole recipe. This recipe also uses enchilada sauce, which you can buy at the store, or you can make your own with our Skinny Ms. Enchilada Sauce!
High Protein Ingredients

This casserole provides almost 30 grams of protein per serving, thanks to all of its protein-rich ingredients. Between all that fantastic, muscle-building protein, the fiber boost from the whole grains and beans, and even the many nutrients found in the veggies, this casserole is just so healthy—and filling! You can even add some more veggies and protein to your plate and serve this casserole with some delicious sides, such as our Creamy Coleslaw or Southwest Cucumber and Avocado Salad.
How to Create this Healthy Chicken Taco Casserole

First, preheat your oven to 375 degrees and grease a 9×13 baking dish. I just use a little spray of olive oil baking spray. Meanwhile, heat the olive oil in a skillet over medium-high heat. Once warm, add the garlic and saute for 1 minute before adding the onion and bell pepper pieces. Cook for about 5 minutes or until soft. Finish by adding in the black beans and taco seasoning and tossing them until warm. Once the mixture is well combined, you can remove the skillet from the heat.

In the baking dish, begin your stack by laying 2 whole wheat tortillas on the bottom, trying to cover as much of the dish as you can. Spread half of the bean mixture, chicken, and cheese over the top. Then, put down another layer of whole wheat tortillas and repeat the stack. Cover the casserole dish with foil and bake for 15 minutes. Remove the foil and bake for another 5 minutes, or until the cheese on top is golden and gooey! Let the casserole cool a bit before cutting into it.

So glad I found this!! It was delicious and easy to make.
Great! Please leave a review when you get a minute.
Delicious, great way to use leftover chicken and ingredients that I had in my pantry.
Was good and quick but would not use the tortillas next time, they were slimy and gooey. The rest of it was delicious though.
Do you think green chile enchilada sauce would work or should I stick with your homemade sauce?
Thanks!
Connie, I think a green chile sauce would be fine.
Thank you for this crowd pleasing recipe! I added a few teaspoons of apple cider vinegar and a tablespoon or so of honey to the homemade enchilada sauce recipe. It was delicious!
Libby, Great! Thank you so much for the feedback.
Soooooooo delicious! It’s in our weekly rotation! Thanks! 🙂
I’ve made this 3 times in 3weeks and it is SO delicious that it gets gobbled up! I’ve doubled the recipe & added cilantro & a few shakes of red pepper flakes (to the onion/garlic saucepan) it can be tweaked easily to be spicy or not and is simply a fabulous meal for healthy Mexican food aficionados!!
