Step 1: Make the Marinade
In a small bowl, whisk together olive oil, lemon juice, minced garlic, oregano, thyme, Dijon mustard, kosher salt, and black pepper until well combined.

Step 2: Marinate the Chicken
Place chicken thighs in a large bowl or zip-top bag. Pour the marinade over the chicken and toss to coat thoroughly. Cover and refrigerate for 1 to 2 hours (or up to 8 hours for more flavor).

Step 3: Prepare to Bake
Preheat oven to 350°F (180°C). Arrange chicken thighs on a sheet pan or baking dish. Pour any leftover marinade over the top.

Step 4: Bake the Chicken
Bake for 40 to 45 minutes, until chicken is cooked through and the internal temperature reaches 175°F (80°C). For crispier skin, turn on the broiler during the last 2–3 minutes of cooking.

Step 5: Rest and Serve
Let chicken rest for 5 minutes before serving. Spoon pan juices over the top and garnish with lemon slices or fresh herbs if desired.
