What You’ll Need
Grab these simple ingredients from your kitchen. You likely have most of these on hand already. High-quality cheese makes a big difference here.
- 4 (6 oz) boneless, skinless chicken breasts
- 3 large yellow onions, thinly sliced
- 3 tablespoons unsalted butter
- 2 tablespoons olive oil
- 1/2 cup beef broth
- 1 tablespoon balsamic vinegar
- 1 teaspoon dried thyme
- 1 cup shredded Gruyère cheese
- 1/2 cup shredded Provolone cheese
- 1/2 teaspoon kosher salt
- 1/2 teaspoon ground black pepper
Step-By-Step Directions
- Preheat the oven to 400°F (200°C).
- In a large skillet, melt butter and 1 tablespoon of olive oil.
- Add sliced onions and cook for 25 to 30 minutes.
- Stir in balsamic vinegar and beef broth.
- Simmer for 2 to 3 minutes until the liquid reduces.
- Season chicken with salt, pepper, and dried thyme.
- Sear chicken in a separate pan for 3 minutes per side.
- Spread caramelized onions over each chicken breast.
- Sprinkle Gruyère and Provolone cheeses over the onions.
- Bake for 15 to 20 minutes until the chicken is done.

How To Serve It
I love serving this chicken over creamy mashed potatoes. The onions create a natural sauce that tastes incredible. You can also pair it with crusty bread to soak up juices. A crisp green salad adds a fresh touch to the plate. It makes a beautiful presentation for a casual dinner party.
Leftovers & Storage
Store any leftovers in an airtight container in the fridge. They will stay fresh for up to three days. Reheat slowly in the oven at 350°F. This keeps the cheese melty without drying out the meat. You can also freeze the cooked chicken for later. Just thaw it in the fridge overnight before reheating.
Make It Even Better (Pro Tips)
- Do not rush the onions; deep color means deep flavor.
- Use a meat thermometer to ensure the chicken stays juicy.
- Deglaze the pan thoroughly to catch every bit of flavor.
- Swap Gruyère for Swiss cheese if you are on a budget.
- Use an oven-safe skillet to save on washing extra dishes.
- Prep the onions on Sunday for a faster weeknight meal.
- Add a splash of white wine for extra acidity and depth.
Easy Ways To Change It Up
- Add sliced mushrooms to the onions for an earthy twist.
- Use chicken thighs instead of breasts for more moisture.
- Top with fresh parsley for a bright pop of color.
- Try smoked provolone for a deeper, wood-fired taste.
Quick Questions
Can I make this ahead of time?
Yes, you can caramelize the onions a day early. Store them in the fridge until you are ready. This cuts your prep time down significantly on busy nights.
What if I do not have an oven-safe skillet?
No problem at all. Just transfer the seared chicken to a baking dish. Top it with onions and cheese before putting it in the oven.
I hope you enjoy this cozy meal as much as I do. It is the perfect way to end a long day. Let me know how it turns out!
