Follow these simple steps to create perfectly roasted honey mustard chicken thighs every time:

1. Preheat Your Oven and Prepare a Baking Sheet: Start by preheating your oven to 400°F (200°C). This high temperature is key to achieving crispy skin and juicy chicken. While the oven is preheating, prepare a large baking sheet. You can line it with parchment paper or foil for easier cleanup, although this is optional. If you want extra crispy skin all around, consider using a wire rack placed inside the baking sheet. This allows air to circulate under the chicken, promoting even crisping.
2. Make the Honey Mustard Marinade: In a large bowl, whisk together the Dijon mustard, honey, olive oil, apple cider vinegar, garlic powder, onion powder, paprika, salt, and black pepper. Ensure all the ingredients are well combined to create a smooth and emulsified marinade. Taste the marinade at this stage and adjust seasonings if necessary. If you prefer a sweeter glaze, add a little more honey. For a tangier flavor, increase the Dijon mustard.
3. Marinate the Chicken Thighs: Add the chicken thighs to the bowl with the marinade. Using your hands or tongs, toss the chicken thoroughly to ensure each piece is evenly coated in the honey mustard mixture. For the best flavor penetration, allow the chicken to marinate for at least 30 minutes at room temperature, or for up to 4 hours in the refrigerator. Longer marinating times will result in more flavorful and tender chicken. If marinating in the refrigerator, bring the chicken to room temperature for about 20-30 minutes before roasting to ensure even cooking.
4. Arrange Chicken on Baking Sheet: Arrange the marinated chicken thighs in a single layer on the prepared baking sheet. Make sure the chicken pieces are not overcrowded, as this can steam the chicken instead of roasting it and prevent proper browning. If necessary, use two baking sheets to ensure adequate spacing. Leave a little space between each thigh to allow for even heat circulation.
5. Roast the Chicken: Place the baking sheet in the preheated oven and roast for 35-40 minutes for bone-in, skin-on thighs, or 25-30 minutes for boneless, skinless thighs. The cooking time may vary depending on the size of the chicken thighs and your oven. To ensure the chicken is cooked through, use a meat thermometer to check the internal temperature. The thickest part of the thigh should reach 165°F (74°C).
6. Baste and Continue Roasting (Optional for Glaze Enhancement): For an extra glossy and flavorful glaze, you can baste the chicken halfway through cooking, around the 20-minute mark. Remove the baking sheet from the oven and brush the chicken thighs with any remaining marinade from the bowl. Return the baking sheet to the oven and continue roasting for the remaining time. This basting step is optional but highly recommended for a more intense honey mustard flavor and caramelized finish.
7. Broil for Extra Crispy Skin (Optional): If you desire even crispier skin, you can broil the chicken for the last 2-3 minutes of cooking. Increase the oven temperature to broil (high heat) and carefully watch the chicken to prevent burning. Broiling can quickly caramelize the sugars in the honey mustard glaze and create a beautifully crispy skin. Broil for a short time and keep a close eye on the chicken as it can burn easily under the broiler.
8. Rest Before Serving: Once the chicken is cooked through and has reached an internal temperature of 165°F (74°C), remove the baking sheet from the oven. Let the chicken rest for 5-10 minutes before serving. Resting allows the juices to redistribute throughout the chicken, resulting in more tender and flavorful meat. Cover the baking sheet loosely with foil while the chicken rests to keep it warm.
9. Garnish and Serve: Garnish the honey mustard roasted chicken thighs with fresh herbs, such as chopped parsley, thyme, or rosemary, if desired. Serve immediately and enjoy! The chicken is delicious served hot, warm, or even at room temperature. The flavorful glaze makes it perfect for pairing with a variety of side dishes.
