01 - Preheat oven to 400°F. Line a baking sheet with parchment paper or aluminum foil.
02 - Combine cream cheese, cheddar, Monterey Jack, jalapeños, green onions, and garlic powder in a small bowl. Mix until thoroughly blended.
03 - Pat chicken breasts completely dry with paper towels. Season both sides generously with salt and pepper.
04 - Using a sharp knife, cut a horizontal pocket into the side of each chicken breast. Do not cut through completely—leave about 1/2 inch uncut on all sides.
05 - Divide the cheese mixture evenly among the 4 breasts, approximately 2 tablespoons per pocket. Secure openings with toothpicks if needed.
06 - Wrap 2 bacon slices around each stuffed breast, tucking the ends underneath. Secure with toothpicks if necessary to hold bacon in place.
07 - Place chicken breasts seam-side down on the prepared baking sheet, leaving space between pieces for even cooking.
08 - Bake for 30–35 minutes until chicken reaches an internal temperature of 165°F and bacon is crispy. If bacon needs extra crisping, broil for 2–3 minutes at the end.
09 - Remove all toothpicks carefully before serving. Let rest for 5 minutes for juicier results.
