In an oven-safe skillet, over medium heat, sauté the chicken in the oil until no longer pink and an instant thermometer inserted into the center reads 165 degrees F, about 7-10 minutes.

Step 3

Transfer the chicken out of the skillet and set it aside.

Step 4

Add the onions and peppers to the skillet and sauté until they are tender, for about 3-5 minutes.

Step 5

Add the chicken back to the skillet and stir in the fajita seasoning, sour cream, and cream cheese. Mix well.

Step 6

Sprinkle the chicken mixture with cheddar cheese.

Step 7

Bake until the cheese is bubbly, about 20 minutes.

Step 8

Serve with your favorite Tex-Mex garnishes like guacamole, sour cream, salsa, and/or hot sauce.
