Ingredients

  • 2 pounds chicken cut into thin strips
  • 3 bell pepper red and yellow, cut into strips
  • ½ red onion sliced thin, large
  • 2 cups pepper jack cheese shredded
  • 8 ounces cream cheese cut into cubes
  • ½ cup sour cream
  • 3 tablespoons olive oil divided
  • 2 tablespoons butter divided
  • 1 tablespoon fajita seasoning homemade
  • 2 tablespoons cilantro chopped, fresh
  • lime zest and juice of 1
  • 1 teaspoon salt
  • ¼ teaspoon black pepper ground

Instructions

    Cup of Yum
  1. Slice each chicken breast into three thin filets, then slice them into strips so you end up with very thin strips.
  2. Heat a skillet to medium, add in half the olive oil, half the butter and chicken strips. Season with half the salt and the fajita seasoning. If your pan is on the smaller side, you might sauté the chicken in two batches like I did.
  3. Sauté until the chicken is almost cooked through, then remove it and set it aside.
  4. Preheat oven to 375°F.
  5. Add in the remaining olive oil, butter, salt and pepper, along with the bell peppers and onions. Sauté for several minutes or until the onions are slightly caramelized.
  6. Turn off the heat, add in the cream cheese, sour cream and lime juice and zest. Stir until melted, then add the chicken back in and half the pepper jack cheese and stir until combined. Add the remaining pepper jack cheese on top and bake for 20-22 minutes or until the cheese is melted and golden.
  7. Serve with a garnish of cilantro and any of your favorite toppings like a dollop of sour cream and pickled jalapeño peppers.

Notes

  • If pepper jack cheese is unavailable, use Mexican cheese blend, cheddar, colby, or Monterey Jack as alternatives.
  • Red onion can be substituted with yellow onion if needed without significant flavor change.
