Cast-Iron Roasted Bone-In Chicken Breasts with Sweet Apples, Melted Leeks & Cider Pan Jus

Instructions

1. 1

   Preheat your oven to 400°F (200°C). Place a 12-inch cast-iron skillet on the middle oven rack so it warms up along with the oven.

   10 min

   Tip: Preheating the skillet ensures immediate heat transfer and helps build a deep, golden crust on the chicken skin without overcooking the meat inside.

2. 2

   In a small bowl, blend 3 tbsp unsalted butter with 1 tbsp fresh sage, 2 tsp fresh thyme leaves, 2 grated cloves garlic, 1/2 tsp kosher salt, and 1/4 tsp freshly cracked black pepper until completely homogenous.

   5 min

   Tip: Make sure the butter is at room temperature so it spreads smoothly without tearing the delicate chicken skin.

3. 3

   Pat 2 large bone-in, skin-on split chicken breasts thoroughly dry with paper towels. Carefully slide your fingers beneath the skin to separate it from the meat, keeping the edges attached. Evenly distribute the herb butter mixture underneath the skin of both breasts, massaging from the outside to spread it across the entire breast. Season the outside of both breasts all over with 3/4 tsp kosher salt and 1/2 tsp freshly cracked black pepper.

   5 min

   Tip: Bone-in chicken breast stays naturally juicy, but stuffing that compound butter right against the flesh guarantees basting from within while roasting.

4. 4

   Toss 2 medium sliced leeks and 2 medium cored and wedged apples together in a bowl with 1 tbsp olive oil, the remaining 1 tsp fresh thyme leaves, 2 smashed cloves garlic, and the remaining 1/4 tsp kosher salt and 1/4 tsp freshly cracked black pepper.

   4 min

   Tip: Slice the leeks thick so they melt and caramelize slowly without burning under the roasting chicken.

5. 5

   Carefully remove the hot cast-iron skillet from the oven and set it over medium heat on the stovetop. Place the chicken breasts skin-side down directly onto the dry, hot iron. Sear undisturbed until the skin renders, turns deep golden brown, and releases naturally, about 5 to 6 minutes. Transfer the chicken breasts skin-side up to a plate temporarily.

   6 min

   Tip: Don't fight the chicken—if it sticks when you try to lift it, give it another 30 to 45 seconds to naturally release as the skin crisps.

6. 6

   Scrape the tossed leek and apple mixture into the rendered fat in the skillet, spreading it into an even layer across the bottom. Nestle the chicken breasts on top of the aromatics, skin-side up.

   2 min

   Tip: The leeks and apples create a flavorful bed that catches the roasting juices and shields the breast bottoms from over-browning.

7. 7

   Transfer the skillet back into the preheated 400°F oven. Roast until the thickest part of the chicken breasts registers 160°F to 162°F on an instant-read thermometer, about 22 to 25 minutes.

   24 min

   Tip: Pull the chicken at 160°F; carryover cooking while it rests will comfortably bring it to the food-safe 165°F mark while preserving moisture.

8. 8

   Carefully remove the skillet from the oven. Transfer the chicken breasts to a warm cutting board or serving platter and tent loosely with foil to rest. Spoon the tender leeks and apples around the chicken, leaving the savory pan drippings in the skillet.

   3 min

   Tip: Resting for at least 8 to 10 minutes lets the juices redistribute through the meat fibers so every bite is succulent.

9. 9

   Return the cast-iron skillet to medium-high heat on the stovetop. Pour in 1/2 cup dry hard apple cider, scraping up any browned bits stuck to the bottom of the pan with a wooden spoon. Boil vigorously until reduced by half, about 2 to 3 minutes.

   3 min

   Tip: Deglazing while the pan is smoking hot lifts all that concentrated, caramelized fond into the sauce.

10. 10

    Whisk in 1/2 cup low-sodium chicken stock, 1 tbsp whole-grain Creole mustard, 1 tsp raw apple cider vinegar, and 1/2 tsp fish sauce. Simmer until thickened to a light, glossy glaze, about 3 minutes. Remove from heat and swirl in the remaining 1 tbsp unsalted butter until melted and velvety.

    4 min

    Tip: The half-teaspoon of fish sauce doesn't taste fishy at all—it adds that essential glutamic punch that ties the sweet cider and savory chicken fond together.

11. 11

    Carve the chicken breasts off the bone and slice crosswise into thick medallions, or serve each half breast whole on the bone. Spoon the warm leeks and apples alongside, then drizzle the glossy cider pan jus generously over the top.

    3 min

    Tip: Pour the jus around the sliced meat and on top of the vegetables rather than over the skin, so that crackling crispiness stays intact.
