Ingredients

Scale

For the Chicken:

4 boneless, skinless chicken breasts (about 6 oz each)
2 tbsp olive oil
1 tsp salt
1/2 tsp black pepper
1 tsp garlic powder
1 tsp dried thyme
1/2 tsp smoked paprika

For the Onion Magic:

4 large yellow onions, sliced thin
3 tbsp butter
1 tbsp olive oil
1 tsp salt
1/2 tsp black pepper
2 tbsp brown sugar
1/4 cup dry white wine (or chicken broth)
2 tbsp balsamic vinegar
2 cloves garlic, minced
1 tsp fresh thyme (or 1/2 tsp dried)

For the Cheese Crown:

1.5 cups Gruyere cheese, grated (or Swiss if you can’t find Gruyere)
1/4 cup Parmesan cheese, grated
2 tbsp fresh chives, chopped
Fresh thyme sprigs for garnish

Instructions

Step 1: Prep the Chicken Preheat oven to 375°F. If your chicken breasts are thick, pound them to an even 3/4-inch thickness (this helps them cook evenly). Season both sides with salt, pepper, garlic powder, thyme, and smoked paprika.

Step 2: Sear That Chicken Heat olive oil in a large oven-safe skillet over medium-high heat. Add chicken breasts and cook for 5-6 minutes per side until golden brown and cooked through (internal temp should hit 165°F). Remove chicken and set aside.

Step 3: Caramelize Those Onions In the same skillet, melt butter with olive oil over medium heat. Add sliced onions, salt, and pepper. Cook, stirring occasionally, for 20-25 minutes until onions are golden brown and caramelized. Don’t rush this part — good things take time!

Step 4: Add the Good Stuff Stir in brown sugar and cook for 2 minutes. Add wine (or broth) and balsamic vinegar, scraping up any browned bits. Add garlic and thyme, cook for another 2 minutes until fragrant.

Step 5: Bring It All Together Nestle the seared chicken breasts back into the onions. Top each piece with Gruyere and Parmesan cheese.

Step 6: Finish in the Oven Transfer the skillet to the preheated oven and bake for 10-12 minutes until cheese is melted and bubbly and chicken is heated through.

Step 7: Serve and Bask in Glory Remove from oven and let rest for 5 minutes. Garnish with fresh chives and thyme sprigs. Serve immediately while that cheese is still doing its gorgeous melty thing.

Notes

Serve over creamy mashed potatoes or egg noodles to catch all that oniony goodness.

A simple green salad with vinaigrette cuts through the richness perfectly.

Crusty bread for sopping up every last drop of those caramelized onions.

A glass of the same white wine you used for cooking makes this feel fancy.
