Creating the 20 Minute Mini Baked Chicken Tacos is as easy as following these straightforward steps:

1. Preheat Oven: Begin by preheating your oven to 375°F (190°C).
2. Cook Chicken: In a large skillet, heat the olive oil over medium heat. Add the ground chicken and cook until no longer pink, breaking it up with a spatula as it cooks.
3. Season Chicken: Once the chicken is cooked, add the taco seasoning and stir well to combine. Cooking for an additional 2 minutes will allow the flavors to meld.
4. Prepare Taco Shells: Arrange the mini taco shells upright in a baking dish. You can use a muffin tin as a support if needed.
5. Fill Taco Shells: Spoon the seasoned chicken into each mini taco shell, filling them generously.
6. Add Cheese: Top each taco with a sprinkle of shredded cheese.
7. Bake Tacos: Place the baking dish in the preheated oven and bake for 8-10 minutes, or until the cheese is melted and bubbly.
8. Prepare Toppings: While the tacos are baking, chop and prepare your desired toppings (lettuce, tomatoes, avocado, etc.).
9. Serve: Once cooked, remove the tacos from the oven. Let them cool for a couple of minutes before garnishing with your selected toppings and sour cream or Greek yogurt.
10. Enjoy: Serve immediately and enjoy your delicious mini tacos with family and friends!
