Equipment

  • Slow Cooker/Crockpot
  • Large Skillet

Ingredients

Main Ingredients

  • 4 boneless, skinless chicken breasts about 2 pounds
  • 3 large yellow onions thinly sliced
  • 2 tbsp butter or olive oil for a lighter option
  • 3 cloves garlic minced
  • 1 tbsp Worcestershire sauce
  • 2 cups low-sodium beef broth
  • 1 tbsp fresh thyme leaves or 1 teaspoon dried thyme
  • 1 bay leaf
  • 2 tbsp all-purpose flour or cornstarch for gluten-free option
  • 1.5 cups Gruyère cheese shredded
  • salt and freshly ground black pepper to taste
  • 1 tbsp balsamic vinegar optional

Instructions

  • Lightly coat your slow cooker with non-stick cooking spray or a thin layer of olive oil to prevent sticking and make cleanup easier.
  • Heat butter in a large skillet over medium heat. Add sliced onions and cook for 8-10 minutes until they begin to soften and turn golden. Add minced garlic and cook for another minute until fragrant.
  • Transfer the caramelized onions to your slow cooker. Whisk together beef broth, Worcestershire sauce, thyme, and flour (or cornstarch) in a bowl until smooth, then pour over the onions.
  • Season chicken breasts generously with salt and pepper on both sides, then nestle them into the onion mixture.
  • Cover and cook on low for 6-7 hours or on high for 3-4 hours. The chicken is ready when it reaches an internal temperature of 165°F (74°C) and shreds easily with a fork.
  • During the final 10-15 minutes of cooking, sprinkle the shredded Gruyère cheese over the chicken. Cover again to allow the cheese to melt.

Notes

For optimal flavor development, don't skip caramelizing the onions before adding them to the slow cooker.
You can substitute mozzarella or Swiss cheese if Gruyère isn't available.
The dish can be stored in the refrigerator for up to 4 days, and flavors actually improve overnight.
