Instructions

1️⃣ Preheat the Oven
Set oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish.

2️⃣ Season the Chicken
Pat the chicken dry and season both sides with salt and pepper.

3️⃣ Optional Sear
For added flavor, heat olive oil in a skillet over medium-high heat. Sear chicken for 2–3 minutes per side until lightly golden, then transfer to the baking dish.

4️⃣ Add the Soup
Pour the condensed French onion soup evenly over the chicken. Cover the dish tightly with foil.

5️⃣ Bake Covered
Bake for 20 minutes.

6️⃣ Add Cheese & Finish Baking
Remove foil. Spoon some of the sauce over each piece, then sprinkle shredded cheese evenly on top. Return to oven, uncovered, and bake 10–15 more minutes, until the internal temperature reaches 165°F (74°C) and the cheese is melted and bubbly.

7️⃣ Rest & Serve
Let the chicken rest for 5 minutes before serving. Spoon extra onion sauce over each portion.
