Ingredients

• Boneless skinless chicken breasts: Look for plump pieces and trim any extra fat for the best sear and tenderness
• Large yellow onions: Choose onions with tight skins and a heavy feel to ensure sweetness when caramelized
• Gruyère cheese slices: A good Swiss or Emmental can also work for that creamy melt and nutty flavor
• Unsalted butter: Fresh butter helps the onions caramelize beautifully without oversalting
• Beef broth low sodium: Use a high quality broth for a richer sauce and control salt levels
• Fresh thyme leaves: Opt for fresh sprigs if you can as they bring out an earthy aroma
• Salt: Choose fine sea salt or kosher salt to bring out flavors gradually
• Freshly ground black pepper: For the most aromatic kick grind it just before cooking

Instructions

Caramelize the Onions

Melt butter in a large skillet over medium heat add sliced onions and cook low and slow stirring often for about 25 minutes you want them deep golden but not burnt this creates that essential sweet base

Sear the Chicken

Pat chicken breasts dry and season both sides with salt and freshly ground black pepper heat another pan over medium high and sear chicken for three minutes per side until browned this gives both flavor and a tender crust

Build the Sauce and Simmer

Add the caramelized onions and fresh thyme into the pan with the chicken pour in beef broth until it just covers the base reduce heat to low cover and simmer gently for fifteen minutes so the chicken soaks up all those flavors

Melt the Cheese

Preheat your broiler arrange the finished chicken breasts in an oven safe dish spoon the onions all over and top each piece with Gruyère cheese broil just two to three minutes until cheese is bubbling and golden

The onions are hands down my favorite part here I will never forget learning to caramelize them from my grandmother she taught me patience was the secret to their magic and her words still echo every time the kitchen fills with that sweet scent
