7 steps
Prepare the Chicken
Season the chicken breasts with salt, pepper, and garlic powder. Heat olive oil in a skillet over medium heat, then add the chicken and cook until golden brown, about 6-7 minutes per side.
Ensure the chicken is cooked through, reaching an internal temperature of 165°F.Caramelize the Onions
In the same skillet, add the sliced onions and cook over low heat until they are caramelized, about 15-20 minutes, stirring occasionally.
Add a splash of beef broth to deglaze the pan and enhance flavor.Add Broth and Thyme
Once the onions are caramelized, add the beef broth and thyme. Stir to combine and let simmer for 5 minutes.
This will create a rich base for the chicken.Combine Chicken and Onions
Return the chicken to the skillet, spoon the onion mixture over it, and sprinkle with Gruyère cheese. Cover and cook on low for an additional 5-7 minutes until the cheese is melted.
Covering the skillet helps melt the cheese evenly.Roast the Carrots
While the chicken cooks, preheat the oven to 400°F (200°C). Toss the carrots with olive oil, salt, and pepper, then spread them on a baking sheet and roast for 20-25 minutes.
Roasting enhances the natural sweetness of the carrots.Prepare Mashed Potatoes
Boil the cubed potatoes until tender, about 15-20 minutes. Drain and mash with butter, milk, salt, and pepper until smooth.
For creamier potatoes, add more milk as needed.Serve
Plate the chicken with caramelized onions, serve alongside roasted carrots and mashed potatoes.
Garnish with fresh thyme for added flavor.
