Ingredients
  

For the Caramelized Onions
  • 3 large Onions thinly sliced
  • 2 tbsp Olive oil
  • 1 tbsp Butter
  • 1 tsp Brown sugar
  • 1 tbsp Balsamic vinegar
  • 1/2 tsp Salt
  • 1/4 tsp Black pepper
For the Chicken
  • 4 Boneless, skinless chicken thighs about 1.5 lbs
  • 1 tbsp Olive oil
  • 1 tsp Smoked paprika
  • 1 tsp Garlic powder
  • 1/2 tsp Onion powder
  • 1/2 tsp Dried thyme
  • 1/2 tsp Salt
  • 1/4 tsp Black pepper
For the Sauce
  • 1/2 cup Chicken broth
  • 1 tbsp Dijon mustard
  • 1 tsp Worcestershire sauce
  • 2 tbsp Fresh parsley chopped, for garnish

Equipment

  • Large oven-safe skillet (e.g., cast iron)
  • Cutting Board
  • Sharp Knife
  • Whisk
  • Small bowl
  • Tongs or spatula

Method
 

Prepare
  • Preheat your oven to 375°F (190°C).
Caramelize the Onions
  • Heat 2 tbsp olive oil and 1 tbsp butter in a large oven-safe skillet (like a cast iron) over medium-low heat. Add the thinly sliced onions.
  • Cook the onions slowly, stirring occasionally, for 25-30 minutes, or until deeply golden brown and very soft. This process should not be rushed as true caramelization takes time.
  • During the last 5 minutes of cooking the onions, stir in the brown sugar, balsamic vinegar, 1/2 tsp salt, and 1/4 tsp black pepper. Remove caramelized onions from the skillet and set aside in a bowl.
Prepare and Sear the Chicken
  • Pat the boneless, skinless chicken thighs dry with paper towels. In a small bowl, combine smoked paprika, garlic powder, onion powder, dried thyme, 1/2 tsp salt, and 1/4 tsp black pepper.
  • Rub the spice mixture evenly all over the chicken thighs.
  • Return the same skillet to medium-high heat and add 1 tbsp olive oil. Once hot, sear the seasoned chicken thighs for 3-4 minutes per side, until nicely browned. They don't need to be cooked through at this stage. Remove chicken from skillet and set aside.
Assemble and Bake
  • Deglaze the skillet by pouring in 1/2 cup chicken broth and scraping up any browned bits from the bottom with a wooden spoon. This adds rich flavor to the sauce.
  • Whisk in 1 tbsp Dijon mustard and 1 tsp Worcestershire sauce into the broth mixture.
  • Return the caramelized onions to the skillet, spreading them evenly across the bottom. Place the seared chicken thighs on top of the onions, ensuring they are nestled well.
  • Transfer the skillet to the preheated oven and bake for 20-25 minutes, or until the chicken is cooked through (internal temperature reaches 165°F / 74°C).
Serve
  • Garnish generously with fresh chopped parsley before serving.
  • Serve immediately with your favorite side dishes such as rice, mashed potatoes, or crusty bread to soak up the delicious sauce.

Notes

For best caramelization, ensure the heat is kept low and the onions are cooked slowly. A cast-iron skillet works wonderfully for this recipe as it goes from stovetop to oven seamlessly. Leftovers can be stored in an airtight container in the refrigerator for up to 3 days.
