Ingredients

Main Ingredients

  • 4 boneless, skinless chicken breasts or thighs (about 1.5–2 lbs)
  • 1/2 cup unsalted butter (melted)
  • 1 cup grated Parmesan cheese
  • 1/2 cup heavy cream
  • 1 tbsp garlic powder
  • 1 tbsp Italian seasoning
  • 1 tsp onion powder
  • 1/2 tsp salt (or to taste)
  • 1/2 tsp black pepper (or to taste)
  • 1/2 tsp crushed red pepper flakes (optional, for heat)
  • 2–3 cloves garlic (minced)
  • fresh parsley (chopped, for garnish)

Instructions 

  • Place chicken breasts or thighs at the bottom of the slow cooker. (Optional: Sear first for extra flavor.)
  • In a bowl, whisk melted butter, Parmesan, heavy cream, garlic powder, Italian seasoning, onion powder, salt, pepper, red pepper flakes, and minced garlic.
  • Pour sauce over chicken, coating evenly. Give a gentle stir or shake to combine.
  • Cover and cook on LOW for 4–6 hours or HIGH for 2–3 hours, until chicken reaches 165°F and is tender.
  • Remove chicken and shred or leave whole. Stir it back into the creamy sauce.
  • Serve hot, spooning sauce over each portion. Garnish with chopped parsley.

Notes

For a thicker sauce, remove lid for the last 30 minutes of cooking or add a pinch of xanthan gum. Try adding low-carb veggies like mushrooms or zucchini during the last hour for extra flavor and nutrition.
