  • 3-4 boneless skinless chicken breasts (2 pounds of chicken)
  • 10.5 ounce can French onion soup
  • 1 packet onion soup mix
  • 1 cup shredded Swiss or provolone cheese Gruyère if you're feeling fancy!
  • ½ cup sour cream or heavy cream for extra richness
  • 3 tablespoons butter
  • 1 cup sliced mushrooms
  • Optional add-in: ½ cup caramelized onions for extra depth

Instructions

  • Spray the crockpot with nonstick cooking spray.
  • Place chicken breasts in the slow cooker. Add the sliced mushrooms. Pour the canned French onion soup over the top.

Notes

This flavorful chicken and oniony sauce is wonderful spooned over mashed potatoes, egg noodles, white rice or brown. Serve with crusty bread for maximum sauce-soaking potential!
Refrigerate leftovers in an airtight container for 3-4 days.
