In a large mixing bowl, combine the softened cream cheese and shredded sharp cheddar cheese until smooth.
Stir in the finely chopped jalapeños, chopped cilantro, garlic powder, onion powder, smoked paprika, and season with salt and pepper. Mix thoroughly until all ingredients are evenly incorporated.
Using a sharp knife, carefully slice each chicken breast horizontally to create a pocket, ensuring you do not cut all the way through.
Generously fill each chicken pocket with the jalapeño and cheese mixture. Use toothpicks to seal the openings if needed.
Place the breadcrumbs in a shallow dish. Carefully coat each stuffed chicken breast in the breadcrumbs, pressing gently to ensure they adhere well.
In an oven-safe skillet, heat the olive oil over medium-high heat. Once the oil is hot, gently add the stuffed and breaded chicken breasts to the skillet. Sear each side for 3-4 minutes.
After searing, transfer the skillet directly into the preheated oven. Bake for an additional 20-25 minutes, or until the chicken is fully cooked.
Once done, remove the skillet from the oven and allow the chicken to rest for 5 minutes.
Notes
Slice each chicken breast into medallions for an impressive display. Garnish with fresh cilantro and serve with lime wedges.
