Preheat the oven: Set to 400°F (205°C). Lightly grease a 9x13-inch baking dish or line it with parchment.
Prep the chicken: Pat the chicken breasts dry.
If they’re thick, slice them in half horizontally to create thinner cutlets for even cooking. Season both sides with 1/2 teaspoon salt, pepper, and smoked paprika.
Brown the chicken: Heat oil in a large skillet over medium-high. Sear chicken 2–3 minutes per side until lightly golden.
Transfer to the baking dish. (They’ll finish cooking in the oven.)
Make the popper topping: In a bowl, mix softened cream cheese, shredded cheddar, chopped jalapeños, minced garlic, onion powder, remaining 1/2 teaspoon salt, and green onions if using. Fold in most of the crumbled bacon, saving a little for topping.
Assemble: Spread the cream cheese mixture evenly over each chicken breast. Sprinkle the reserved bacon on top.
Bake: Cook 15–18 minutes, or until the chicken reaches an internal temperature of 165°F (74°C) and the topping is bubbly.
If you want extra color, broil for 1–2 minutes at the end—watch closely.
Rest and serve: Let the chicken rest 5 minutes. Garnish with chopped cilantro or parsley and a squeeze of lime if you like.
