2 tbsp butter

1 tsp olive oil

Instructions

Preheat the oven to 375°F (190°C).
In a skillet over medium heat, melt the butter with the olive oil. Add the sliced onions and cook, stirring occasionally, until soft and caramelized, about 15 minutes.
Season the chicken breasts with garlic powder, salt, and pepper.
Place the chicken in a greased baking dish. Spoon the caramelized onions evenly over each piece, then pour the French onion soup over the chicken and onions.
Sprinkle the shredded Swiss or Gruyère cheese evenly on top.
Bake uncovered for 30–35 minutes, or until the chicken reaches an internal temperature of 165°F (75°C) and the cheese is bubbly and golden.
Garnish with fresh thyme or parsley before serving, if desired.

Notes

Swiss or Gruyère cheese can be used interchangeably for slightly different flavor profiles.

Add an extra half onion for deeper caramelized flavor.

Sliced mushrooms can be cooked with the onions for added richness.

Store leftovers in an airtight container in the refrigerator for up to 3 days.

Reheat in a 350°F (175°C) oven until warmed through, or microwave in short intervals.

Freeze after baking and cooling completely for up to 2 months. Thaw in the refrigerator before reheating.
