Honey-mustard is a favorite combination of many people for a reason, it's delicious! Spicy and sweet with lots of savory mushrooms, this dish is high in protein and big on flavor. Enjoy with a side of fresh green salad!


  • 1 tablespoon olive oil (or avocado oil)
  • 1/2 red onion, chopped
  • 2.5 tablespoons dijon mustard
  • 2 tablespoons honey
  • 1 tsp dried thyme
  • 1/4 tsp garlic powder
  • 1 tsp salt
  • 1 cup warm water
  • 6 Boneless Skinless Chicken Breasts
  • 8 oz baby bella mushrooms, sliced
  • 2 tablespoons flour (*see Tip for gluten-free option)

Makes 6


    1. In a small bowl, combine oil, chopped onion, mustard, honey, thyme, garlic powder, salt and warm water. Stir to combine using a fork.
    2. In your slow cooker, lay chicken breasts on the bottom (frozen chicken is ok!).
    3. Next spread sliced mushrooms over the chicken.
    4. Finally, pour sauce over the mushrooms and chicken.
    5. Cook on LOW for 5-6 hours.
    6. During the last 30 minutes of cooking, remove about 1/2 cup of liquid from the slow cooker using a glass liquid measuring cup or something similar. Sprinkle 2 tablespoons of flour into the 1/2 cup of liquid and mix quickly using a fork, then pour back into the slow cooker for last 30 minutes of cooking to thicken the sauce.

Note: Every slow cooker is different. Keep an eye on your chicken the first time you make this. If needed, for those who have a slow cooker that runs hot, you can add an additional 1/2 cup water during cooking. Also, if using fresh or thawed chicken, your cooking time will be closer to 5 hours, frozen chicken will be closer to 6hrs.

Tip: If you are eating gluten-free you can substitute Tapioca flour (sometimes called tapioca starch) in place of the flour.
