Step 1: Prepare the Chicken Filling
In a skillet over medium heat, add the olive oil and shredded chicken.
Sprinkle in the taco seasoning and pour in ¼ cup of water. Stir well to coat the chicken evenly. Simmer for 2–3 minutes until the mixture thickens. Remove from heat and set aside.
Step 2: Assemble the Tacos
Preheat the oven to 400°F (200°C).
Lightly spray a muffin tin with cooking spray to prevent sticking.
Warm the mini tortillas slightly (either in the microwave or in a pan) to make them pliable.
Place each tortilla into a muffin cup, gently pressing to form a taco shell shape.
Step 3: Fill and Bake the Tacos
Spoon the seasoned chicken mixture into each tortilla, filling it halfway.
Top with a generous sprinkle of shredded cheese.
Bake in the preheated oven for 10–12 minutes, or until the tortillas are crisp and the cheese is melted and bubbly.
Step 4: Garnish and Serve
Remove the tacos from the oven and let them cool slightly.
Add your desired toppings, such as sour cream, diced tomatoes, jalapeños, or cilantro, and serve warm.
