Step‑by‑Step Instructions for French Onion Chicken Rice Bake

Preheat your oven to 375°F (190°C).
Season the chicken breasts generously with salt and black pepper on both sides. Heat a skillet over medium-high heat with olive oil and sear each chicken breast for about 2 minutes on each side until golden brown. Set the chicken aside.
In the same skillet, reduce heat to medium, add butter, and melt completely. Add thinly sliced onions and stir frequently for approximately 15 minutes until caramelized and translucent.
Introduce minced garlic to the caramelized onions, cooking for an additional 30 seconds until fragrant.
Add long-grain white rice, stirring to combine with the onion and garlic mixture. Allow it to absorb the flavors for about a minute.
Pour in chicken broth and sour cream, along with dried thyme, salt, and pepper to taste. Bring to a gentle simmer while stirring continuously.
Transfer the rice mixture to a greased baking dish, then place the seared chicken breasts on top.
Generously sprinkle the grated Gruyère cheese over the chicken and rice mixture.
Cover the baking dish with aluminum foil and bake for 35 minutes.
After 35 minutes, remove the foil and continue baking for an additional 5 minutes for a golden crust.
Let the bake rest for about 5 minutes before garnishing with freshly chopped parsley.

Store leftovers in an airtight container for up to 3 days. Freeze portions for up to 2 months, and gently reheat before serving.
