In a pan, heat the olive oil over medium heat. Add the shredded chicken, cumin, garlic powder, onion powder, salt, and pepper. Stir to combine.
Warm the tortillas in the microwave for about 20 seconds to make them pliable. Fill each tortilla with a portion of the chicken mixture and roll tightly.
Spread 1 cup of the enchilada sauce on the bottom of a baking dish. Place the rolled tortillas seam-side down in the dish.
Pour the remaining enchilada sauce over the tortillas and sprinkle the shredded Monterey Jack cheese on top.
Bake in the preheated oven for 20-25 minutes, until the cheese is melted and the sauce is bubbly.
Garnish with chopped cilantro and serve with sour cream.
Notes
These enchiladas can be prepared ahead of time and refrigerated until ready to bake.
