Ingredients
For the chicken:
- 6 bone-in or boneless chicken thighs
- 1 teaspoon salt
- 1 teaspoon black pepper
- 1 teaspoon garlic powder
- ½ teaspoon smoked paprika
- 2 tablespoons olive oil
For the French onion sauce:
- 3 large yellow onions, thinly sliced
- 3 tablespoons butter
- 3 garlic cloves, minced
- 1 teaspoon fresh thyme (or ½ teaspoon dried)
- 1 teaspoon sugar (helps quick caramelizing)
- 1 teaspoon salt
- 1 tablespoon flour (for thickening)
- 1 cup beef broth (or chicken broth)
- ½ cup shredded Gruyère or mozzarella cheese
- 1 tablespoon fresh parsley for garnish
Instructions
- Season the chicken: Mix salt, pepper, garlic powder, and paprika. Coat chicken thighs evenly. This builds bold flavor from the start.
- Brown the chicken: Heat oil and sear chicken skin-side down for 4–5 minutes. Flip and cook 3 more minutes. Remove and set aside. Browning locks in juices and adds deep color.
- Caramelize the onions: Add butter, sliced onions, thyme, sugar, salt, and pepper. Cook 10–12 minutes until deep golden. Stir often so they don’t burn. This step gives the dish its signature French onion flavor.
- Add garlic and flour: Add garlic and cook 1 minute. Stir in flour to thicken the sauce. Cook another minute so flour loses its raw taste.
- Deglaze with broth: Pour in broth and scrape the pan to lift browned bits. These bits turn into rich, savory flavor.
- Add chicken back to pan: Place chicken thighs over the onions. Spoon the sauce over them. Cover and simmer 15–20 minutes until chicken cooks through.
- Add cheese: Sprinkle cheese over chicken. Cover 2 minutes until melted. You can also broil for a golden top.
- Serve: Garnish with parsley and serve hot. It pairs well with rice, mashed potatoes, pasta, or crusty bread.
