Prepare the Chicken:
Preheat your oven to 375°F (190°C).
Pat the chicken thighs dry with a paper towel and season both sides with smoked paprika, garlic powder, salt, and black pepper.
Sear the Chicken:
Heat the olive oil in a large skillet over medium-high heat.
Place the chicken thighs skin-side down and sear for 3–4 minutes until golden and crispy. Flip and sear the other side for another 2 minutes. Remove the chicken and set aside.
Make the Jalapeño Peach Glaze:
In the same skillet, reduce the heat to medium and add the diced peaches, jalapeños, honey, soy sauce, apple cider vinegar, grated ginger, and red pepper flakes.
Stir and let the mixture simmer for 5–7 minutes, until the peaches soften and the glaze thickens slightly. (For a smoother sauce, blend the mixture in a food processor or blender, then return it to the skillet.)
Glaze and Bake:
Return the chicken thighs to the skillet, spooning the jalapeño peach glaze generously over each piece.
Transfer the skillet to the preheated oven and bake for 20–25 minutes, or until the chicken is fully cooked (internal temperature of 165°F/74°C).
Serve:
Remove the chicken from the oven and let it rest for 5 minutes.
Spoon extra glaze over the chicken before serving. Garnish with fresh peach slices or chopped cilantro for a burst of color.
