Ingredients

Scale
  • 4 boneless, skinless chicken breasts
  • 4 large yellow onions, thinly sliced
  • 2 tablespoons unsalted butter
  • 3 garlic cloves, minced
  • 2 cups beef broth
  • 1/2 cup dry white wine (optional, can substitute with extra broth)
  • 1 tablespoon Dijon mustard
  • 1 teaspoon dried thyme or 1 tablespoon fresh thyme
  • Salt to taste (start with 1 teaspoon)
  • Black pepper to taste (start with 1/2 teaspoon)
  • 1/2 cup heavy cream
  • 8 slices baguette, toasted
  • 1 1/2 cups shredded Gruyere cheese

Instructions

  1. Thinly slice 4 large yellow onions (about 10 minutes).
  2. Melt 2 tablespoons unsalted butter in a large skillet over medium-low heat. Add sliced onions and a pinch of salt. Cook slowly, stirring occasionally, until deep golden brown and sweet, about 30-40 minutes. Add a splash of water if onions stick.
  3. Stir in 3 minced garlic cloves during the last 2 minutes of cooking the onions.
  4. Transfer caramelized onions and garlic into the crockpot. Place 4 boneless, skinless chicken breasts on top.
  5. Pour in 2 cups beef broth and 1/2 cup dry white wine (or extra broth). Stir in 1 tablespoon Dijon mustard and 1 teaspoon thyme. Season with salt and pepper (start with 1 teaspoon salt and 1/2 teaspoon pepper).
  6. Cover and cook on low for 6-8 hours or on high for 3-4 hours until chicken is tender and reaches an internal temperature of 165°F (74°C).
  7. About 15 minutes before serving, stir in 1/2 cup heavy cream and mix gently until combined and heated through.
  8. While cream warms, toast 8 slices of baguette in the oven at 350°F (175°C) for 5-7 minutes until slightly crisp. Top each slice with about 1/4 cup shredded Gruyere cheese. Broil for 2-3 minutes until cheese is melted, bubbly, and golden brown. Watch carefully to avoid burning.
  9. Serve each chicken breast topped with generous amounts of onion sauce and one or two slices of Gruyere toast. Enjoy hot.

Notes

Caramelizing onions low and slow is key for deep flavor; add garlic last to avoid burning. Use beef broth for richer flavor. Gruyere cheese should be freshly shredded for best melt. To thicken sauce, mix 1 teaspoon cornstarch with 1 tablespoon cold water and stir in during last 10 minutes of cooking. For dairy-free, substitute heavy cream with coconut cream and use vegan cheese. Chicken thighs can be used for juicier meat with slight cooking time adjustment. Store chicken and sauce separately from Gruyere toast to avoid sogginess.
