Ingredients for Barbecued Oven Baked Chicken Thighs

  • Chicken Thighs
  • Seasoning Salt
  • Fresh Ground Black Pepper
  • 2 tablespoons olive oil or vegetable oil
  • Garlic
  • 1 medium onion, thinly sliced
  • Green Bell Pepper
  • Yellow Mustard
  • 1/2 cup ketchup
  • 2 tablespoons cider vinegar
  • 1 teaspoon liquid smoke
  • Dark Brown Sugar
  • 1 teaspoon chili powder
  • Cayenne Pepper

How to Make Barbecued Oven Baked Chicken Thighs

  1. Preheat oven to 350°F (175°C). Grease a large (9x13 inch) casserole dish.
  2. Thinly slice one medium onion and one green bell pepper. Arrange them on the bottom of the prepared baking dish.
  3. Season 2 lbs bone-in, skin-on chicken thighs generously with salt and pepper. Heat 2 tablespoons of oil in a large skillet over medium-high heat. Brown the chicken thighs on both sides for about 2-3 minutes per side.
  4. Place the browned chicken thighs on top of the onion and pepper slices in the casserole dish.
  5. In a medium bowl, whisk together: 1/4 cup French's yellow mustard, 1/2 cup ketchup, 2 tablespoons cider vinegar, 1 teaspoon liquid smoke, 2 tablespoons brown sugar, 1 teaspoon chili powder, 2 cloves minced fresh garlic, 1/4 teaspoon cayenne pepper (optional), and 1/4 teaspoon black pepper.
  6. Add 1/4 teaspoon salt to the sauce, or to taste.
  7. Pour the sauce evenly over the chicken thighs in the casserole dish.
  8. Using tongs or clean hands, gently turn the chicken to ensure it's fully coated in the sauce.
  9. Bake for 40-60 minutes, or until the chicken is cooked through (internal temperature reaches 165°F) and the sauce is bubbly. If you skipped browning the chicken, increase the baking time to 50-70 minutes.
  10. Let rest for 5-10 minutes before serving. Enjoy with your favorite sides!

Chef's Tip for Extra Flavor

Chef's secret: layers of flavor make a dish truly memorable! Consider what a little extra something could bring – perhaps a touch of acidity like a good vinegar or citrus zest, a hint of smokiness from paprika, a bit of umami from mushrooms or soy sauce, or a sprinkle of toasted nuts for texture. Experiment and taste as you go!
