Tender and juicy Shredded Mexican Style Chicken is layered into crispy Taco shells, topped with shredded cheese and baked to golden perfection in the oven to create these Baked Chicken Tacos. What my family loves about it is that we can each add just whatever toppings we like in any quantity we chose. YUMM!
Preheat oven to 400F. Spray a 9x13 baking dish with nonstick spray and set aside. Heat olive oil over medium heat in a medium skillet.
Add onion to skillet and cook for 2-3 minutes, or until the onion is translucent and fragrant. Stir in the chicken, tomatoes, and green chilis. Stir to combine fully. Reduce to simmer and allow to cook for 5-8 minutes.
Place the taco shells in the baking dish, standing up. I was able to fit 10 taco shells in the dish by adding 2 on each side.Spoon 1 tablespoon of beans into the bottom of each taco shell. Top with the chicken mixture, almost to the top of each shell.
