Ingredients
For the Chicken:
-
4 boneless, skinless chicken breasts
-
Salt and pepper, to taste
-
1/2 tsp garlic powder
-
1/2 tsp dried thyme
-
2 tbsp olive oil (or butter)
For the Onion Sauce:
-
2 large yellow onions, thinly sliced
-
2 tbsp butter
-
1 tbsp olive oil
-
2 cloves garlic, minced
-
1 tsp sugar (helps caramelize)
-
1/4 cup dry white wine (or chicken broth)
-
1 cup low-sodium beef broth (or chicken broth)
-
1 tsp Worcestershire sauce
-
Fresh thyme sprigs (optional)
-
Salt and pepper to taste
To Finish:
-
4 slices provolone, Swiss, or gruyère cheese (or shredded)
-
Optional: chopped parsley or thyme for garnish
Instructions
Step 1: Caramelize the Onions
-
In a large skillet over medium heat, add butter and olive oil.
-
Add sliced onions, sprinkle with sugar, and cook slowly for 20–25 minutes, stirring occasionally.
-
When onions are deep golden brown, add garlic and cook 1 minute more.
-
Pour in white wine (or broth) to deglaze the pan, scraping up any browned bits.
-
Simmer until wine is mostly reduced, then stir in beef broth and Worcestershire sauce. Simmer 5 minutes more.
-
Transfer onions to a bowl and wipe out the skillet.
Pro Tip: The more time you give the onions, the deeper the flavor!
Step 2: Cook the Chicken
-
Pat chicken breasts dry and season with salt, pepper, garlic powder, and dried thyme.
-
Heat olive oil in the same skillet over medium-high heat.
-
Sear chicken breasts 4–5 minutes per side until golden brown. They don’t need to be fully cooked through yet.
-
Reduce heat to medium-low.
Step 3: Bring It Together
-
Return the caramelized onions to the skillet with the chicken.
-
Spoon onions over and around the chicken.
-
Top each chicken breast with a slice of cheese.
-
Cover the skillet with a lid and cook for another 5–8 minutes, or until the chicken is cooked through (internal temp 165°F / 74°C) and cheese is melted.
Step 4: Garnish & Serve
-
Garnish with chopped parsley or thyme if desired.
-
Serve hot, spooning extra onion sauce over the chicken.
