Before you start

Before beginning, ensure the oven is preheated to 400°F (200°C) to guarantee consistent roasting. Wash and dry the Brussels sprouts thoroughly, removing any damaged outer leaves.

Peel and chop the sweet potatoes into uniform, bite-sized cubes to ensure they cook through at the same time as the chicken. Have the garlic butter melted and ready in a small pitcher, and ensure the chicken is patted dry with paper towels to help the skin crisp up effectively in the hot oven.

Ingredients at a glance (6)
  • 4 bone-in skin-on chicken thighs
  • 1 lb Brussels sprouts, halved
  • 2 cups sweet potato cubes
  • 4 tbsp unsalted butter, melted and mixed with garlic
  • fresh thyme sprigs, to taste
  • flaky salt, to taste

Instructions

Preparation and Arrangement

  1. Arrange the ingredients
    Preheat your oven to 400°F (200°C). Line a large sheet pan with parchment paper. Arrange the chicken thighs, halved Brussels sprouts, and sweet potato cubes in a single layer on the pan to ensure even roasting.
    Look for Ingredients are in a single layer
    Tip Ensure the chicken skin is facing up for maximum crispiness during roasting.

Check that all ingredients are arranged in a single layer on the parchment-lined pan. The chicken skin should be facing upward, and the vegetables should be spread out to allow for proper air circulation. This initial setup is crucial for ensuring that everything cooks evenly and achieves the desired level of crispiness without any overlapping components that might lead to soggy textures.

Roasting Process

  1. Season and roast
    Pour the melted garlic butter evenly over the chicken and vegetables. Scatter the fresh thyme sprigs and flaky salt across the tray. Place the pan in the oven and roast until the vegetables are tender and the chicken is fully cooked.
    Look for Butter is drizzled and herbs are distributed
    Tip Use a small pitcher to pour the butter for better control and even coverage.

During the roasting phase, the garlic butter will melt and mingle with the juices from the chicken. The kitchen should smell fragrant and savory as the thyme releases its oils.

Monitor the pan to ensure the edges of the sweet potatoes are beginning to brown and the Brussels sprouts are softening. The heat should be consistent throughout the oven to ensure even browning across the entire surface of the pan.

Final Browning and Resting

  1. Finalize and rest
    Continue roasting until the chicken reaches an internal temperature of 165°F (74°C) and the skin is golden brown. Remove from the oven and let the chicken rest for 5 minutes before serving.
    Look for Chicken skin is golden and crispy
    Safe temperature 165°F (74°C) internal temperature (poultry)
    Tip A metal spatula is helpful for lifting the chicken thighs without tearing the skin.

The final phase involves achieving the perfect level of browning on the chicken skin. Once the chicken reaches 165°F (74°C), the vegetables should be fully tender and golden-edged. Remove the pan from the oven and let it sit for a few minutes. This allows the cooking process to stabilize and ensures that the final result is perfectly cooked and ready to be served immediately while still warm.

Common mistakes

Avoid overcrowding the pan, as this causes the ingredients to steam rather than roast, preventing the skin from crisping and the vegetables from caramelizing. Ensure the butter is distributed evenly; pooling butter in one area can lead to uneven cooking.

Additionally, do not skip the resting period, as cutting into the chicken immediately after taking it out of the oven causes the juices to escape, resulting in drier meat. Always verify the temperature with a meat thermometer.

How to tell it’s done

The dish is ready when the chicken thighs reach an internal temperature of 165°F (74°C) in the thickest part. The skin should appear deeply golden and crispy, while the sweet potato cubes should be fork-tender.

The Brussels sprouts should be lightly charred around the edges, indicating they are fully cooked and flavorful. Let the chicken rest for at least 5 minutes to allow the juices to redistribute, ensuring every bite remains moist and tender when served.
