Looking for a dish that’s both comforting and refined? Meet the Savory Onion Chicken Delight. This recipe combines tender chicken with caramelized onions and gooey Gruyere cheese, offering a flavor-packed meal perfect for any season.
Boneless chicken breasts are the star of the dish, providing a lean, protein-rich base that absorbs all the delicious flavors. Olive oil is used to caramelize the onions, enhancing their natural sweetness. Three large onions form the heart of the dish, offering a slightly sweet, deeply savory profile once caramelized.
Beef broth adds depth and a savory backbone to the sauce, while balsamic vinegar introduces a tangy, slightly sweet note that balances the richness. Dried thyme and dried rosemary bring an earthy, aromatic dimension to the dish. Finally, the Gruyere cheese, with its nutty, melty goodness, crowns the dish, creating a delightful crust.
This dish pairs wonderfully with a side of creamy mashed potatoes or roasted vegetables. A light, crisp salad with a tangy vinaigrette can also complement the richness of the chicken beautifully.
Preheat your oven to 400°F so it's hot and ready when your dish is assembled. Meanwhile, grab a large skillet and heat the olive oil over medium heat. Toss in the sliced onions and let them cook down slowly, stirring occasionally. It takes about 15 minutes for them to caramelize, but you’ll want to watch them closely near the end to avoid burning.
Once the onions are beautifully browned and fragrant, pour in the beef broth and balsamic vinegar. Sprinkle in the thyme, rosemary, and a good pinch of salt and pepper. Let everything simmer together for about 5 minutes, stirring occasionally to meld those flavors together.
Place the chicken breasts in a baking dish in a single layer. Pour the onion mixture over the chicken, making sure each piece is well-covered. Top everything with a generous layer of Gruyere cheese, ensuring every inch is blanketed for that perfect melt.
Slide the dish into your preheated oven and bake for 25-30 minutes. You’re looking for the chicken to be cooked through and the cheese to be bubbly and golden. Once done, let it rest for a few minutes before serving.
