In a mixing bowl, whisk together the maple syrup, Dijon mustard, olive oil, minced garlic, thyme, salt, and black pepper until well combined. This will create a flavorful marinade that balances sweetness and tang.

Place the chicken thighs in a large resealable plastic bag or a shallow dish. Pour the marinade over the chicken, ensuring each piece is well coated. Seal the bag or cover the dish and refrigerate for at least 30 minutes, or up to 2 hours for maximum flavor.

Preheat your oven to 400°F (200°C). This high temperature will help to caramelize the marinade on the chicken, creating a delicious crust.

Remove the chicken from the marinade and place it in a baking dish, skin side up. Discard any leftover marinade to avoid contamination.

Bake in the preheated oven for 30-35 minutes, or until the internal temperature reaches 165°F (74°C) when checked with a meat thermometer. This ensures the chicken is fully cooked and safe to eat.

Once cooked, remove the chicken from the oven and let it rest for 5 minutes. This allows the juices to redistribute, making the chicken more tender.

Garnish with chopped fresh parsley if desired, and serve warm with your favorite sides.
