How to make Baked Chicken Tacos:
Step 1: Prepare the oven. Preheat it to 400 degrees F. Using a nonstick spray, grease a 9 x 13-inch baking dish.
Step 2: In a medium skillet, heat the olive oil over medium heat. Once hot, add the onion and saute for about 2 to 3 minutes or until clear and aromatic.
Step 3: Add the chicken, taco seasoning, fully drained tomatoes, and green chiles. Stir well until completely combined. Decrease the heat to a simmer and let it cook for about 5 to 8 minutes.
Step 4: In the baking dish, place the taco shells standing up. Place the baking dish in the preheated oven and bake the taco shells for about 5 minutes until crisp. Take them out of the oven when done.
Step 5: Into the bottom of each taco shell, spoon 1 tbsp of beans. Add the chicken on top, then generously sprinkle with shredded cheese. Return to the oven and continue baking the tacos for another 7 to 10 minutes or until the cheese has completely melted and the edges of the shells are browned.
Step 6: Before serving, top the tacos with your preferred toppings like jalapenos, sour cream, cilantro, and salsa.
Enjoy!
