Ingredients

Main Ingredients

  • 1 lb chicken breast, cubed (boneless, skinless)
  • 8 oz mushrooms, sliced (white or cremini)
  • 1 cup heavy cream
  • 1 cup shredded cheddar cheese sharp gives more flavor
  • 1/2 cup chicken broth low-sodium preferred
  • 2 cloves garlic, minced
  • 1 teaspoon onion powder
  • Salt and pepper to taste
  • Fresh parsley, for garnish

Instructions

Preparation

  • Cube the chicken, slice the mushrooms, and mince the garlic.
  • Pat the chicken dry to achieve a light brown if searing.

Cooking

  • Place the cubed chicken and sliced mushrooms into the crockpot.
  • Add the minced garlic, onion powder, salt, and pepper; toss to distribute seasonings.
  • Pour the chicken broth and heavy cream over the chicken mixture. Stir gently to combine.
  • Cover and cook on low for 6–8 hours or high for 3–4 hours (chicken should reach 165°F).
  • 30 minutes before serving, sprinkle shredded cheddar over the top and stir until melted and incorporated.
  • Taste and adjust seasoning, then garnish with fresh parsley before serving.

Notes

For a lighter version, consider pairing with cauliflower mash, riced cauliflower, or a crisp salad. It can be stored in the refrigerator for up to 3–4 days or frozen for 2 months.
