Step 1

In a bowl, add the chicken thighs, salt, pepper, garlic, dried parsley, and olive oil, and toss until evenly coated.

Step 2

Add the chicken to a skillet on medium-high heat. Sear until golden brown, about 4 minutes. Flip and cook the other side of the chicken, 2 minutes. Remove the chicken from the pan and set aside.

Step 3

Preheat oven to broil.

Step 4

Add the butter, sliced onions, salt, and pepper to the same pan, stirring occasionally until softened. Reduce heat to low and cook until they are deeply caramelized, about 1 hour.

Step 5

Add thyme and beef broth and bring the mixture to a simmer.

Step 6

Add the chicken on top of the onions, and sprinkle with Gruyère cheese.

Step 7

Broil for 5 minutes, until the cheese is melted and golden brown.

Step 8

Serve over bread.
