  • ½ cup dry red wine (like Pinot Noir) or beef broth

🍗 Instructions

  1. Prep the chicken

    • Pat chicken breasts dry and season with salt and pepper.
    • Heat olive oil and 1 tbsp butter in a large oven-safe skillet over medium-high heat.
    • Sear chicken 5–6 minutes per side until golden and cooked through (165°F). Remove and set aside.

  2. Caramelize the onions

    • In the same pan, melt 1 tbsp butter. Add onions and cook over medium-low heat for 15–20 minutes , stirring occasionally, until deep golden and sweet.
    • Stir in garlic and thyme; cook 1 minute more.

  3. Deglaze the pan

    • Pour in red wine (or broth) and Worcestershire sauce.
    • Scrape up browned bits from the bottom of the pan.
    • Simmer 3–5 minutes until slightly reduced.

  4. Assemble & bake

    • Return chicken to the pan, nestling it into the onions.
    • Sprinkle with Gruyère and Parmesan.
    • Broil on high for 3–5 minutes until cheese is bubbly and golden.

  5. Serve hot

    • Let rest 5 minutes. Garnish with fresh thyme or parsley.
    • Serve with:
      • Mashed potatoes
      • Buttered egg noodles
      • Crusty bread (to soak up the sauce!)

Tips for the Best French Onion Chicken

🔥 Slice onions evenly — for even caramelization
🔥 Cook onions low and slow — don’t rush the caramelization
🔥 Use an oven-safe skillet — no need to transfer to a baking dish
🔥 Don’t skip the wine — it adds depth (use broth if avoiding alcohol)
🔥 Broil with caution — watch closely to avoid burning
