Ingredients

Scale

Main Ingredients:

  • 4 boneless chicken breasts
  • 6 cups (1.4 kg) sliced yellow onions
  • 1⅓ cups (170 grams) shredded Swiss cheese

Seasonings and Spices:

  • 1 tablespoon all-purpose flour
  • 1 tablespoon Worcestershire sauce
  • 1 teaspoon sugar
  • 1 teaspoon fresh thyme leaves (or ¼ teaspoon dried)
  • 1 rounded teaspoon Dijon mustard
  • Sea or kosher salt
  • Black pepper

Fats and Liquids:

  • 2 tablespoons melted butter

Instructions

  1. Prepare the crockpot by liberally coating a 4-5 quart (3.8-4.7 liters) slow cooker with cooking spray, then evenly spread thinly sliced onions across the bottom.
  2. Create a flavor-packed sauce by thoroughly whisking melted butter, Worcestershire sauce, Dijon mustard, all-purpose flour, granulated sugar, fresh thyme leaves, salt, and freshly ground black pepper in a mixing bowl until smooth and well-combined.
  3. Thoroughly drizzle the prepared sauce over the onions, gently tossing to ensure every onion slice is evenly coated with the aromatic mixture.
  4. Carefully arrange chicken breasts atop the sauce-coated onions, then generously season the chicken with additional salt and freshly cracked black pepper to enhance the overall flavor profile.
  5. Secure the slow cooker lid and cook on low temperature for 5-7 hours or on high temperature for 3-4 hours, allowing the chicken to become exceptionally tender and the onions to caramelize beautifully.
  6. During the final cooking stage, delicately layer Swiss cheese over each chicken breast, then replace the lid to allow the cheese to melt into a luxurious, creamy topping.
  7. Plate the chicken by transferring each piece onto a serving platter, generously spooning the rich, caramelized onions over the top and drizzling the flavorful cooking juices around the dish for added moisture and taste.

Notes

  • Slow cooker magic transforms ordinary chicken into a mouthwatering French-inspired feast bursting with caramelized onion goodness.
  • Worcestershire sauce and Dijon mustard create a tangy base that infuses deep, complex flavors throughout the entire dish.
  • Cooking low and slow allows chicken to become incredibly tender while onions develop rich, sweet caramelization.
  • Swiss cheese melts luxuriously over chicken, adding creamy texture and complementing the savory onion sauce perfectly.
  • Minimal prep time means you’ll have a restaurant-quality meal waiting when you return home after a busy day.
  • Serve with crusty bread or roasted vegetables to soak up the delicious cooking juices and complete this comforting meal.
