Notes on Ingredients

For this recipe, you’ll need:

  • Chicken Breasts: Choose skinless, boneless halves for easy preparation.
  • Baby Portabella Mushrooms: Their rich flavor pairs perfectly with chicken.

How to Make Keto Mushroom-Stuffed Chicken Breasts

  1. Preparation: Preheat your oven to 400°F (200°C) and position the rack in the center. Pound the chicken breasts to an even 1/2-inch thickness using a meat mallet.
  2. Mushroom Filling: In a saucepan, melt butter over medium heat. Sauté the sliced mushrooms until softened, then add garlic and thyme. Continue to cook until the mushrooms are tender and most liquid has evaporated. Reduce heat and stir in cream cheese until melted. Season with salt and remove from heat.
  3. Assembling the Chicken: Spoon the mushroom mixture onto each chicken breast, roll them up, and secure with toothpicks. Place seam-side up in a baking dish.
  4. Baking: Bake for 20 minutes, then brush with Dijon mustard and sprinkle with Parmesan cheese. Return to the oven and bake for an additional 15-20 minutes until the chicken is fully cooked and juices run clear.
  5. Serving: Discard toothpicks before serving. Enjoy your delicious, low-carb meal!

  • 4 skinless boneless chicken breast halves
  • 2 tablespoons butter
  • 1 8 ounce package baby portabella mushrooms, sliced
  • 2 cloves garlic minced
  • ½ teaspoon thyme
  • 1 8 ounce package cream cheese
  • ¼ teaspoon salt
  • toothpicks
  • 2 tablespoons Dijon mustard
  • 2 tablespoons grated Parmesan cheese or as needed


  • Preheat the oven to 400 degrees F (200 degrees C). Set an oven rack in the center of the oven.
  • Place chicken breasts between 2 sheets of heavy plastic on a solid, level surface. Firmly pound with the smooth side of a meat mallet to 1/2-inch thickness.
  • Melt butter in a saucepan over medium heat. Add mushrooms and cook until softened, about 4 minutes. Add garlic and thyme and cook until mushrooms are tender and most of the liquid has evaporated, 4 to 5 minutes. Reduce the heat to medium-low. Stir in cream cheese and season with salt. Cook and stir until cream cheese has completely melted. Remove from the heat.
  • Spoon the mushroom-cream mixture onto chicken breasts. Wrap chicken around the mixture and secure with toothpicks. Set chicken bundles, seam-side up, in a baking dish.
  • Bake in the preheated oven for 20 minutes. Remove from the oven and brush with Dijon mustard. Sprinkle with Parmesan cheese and return to the oven.
  • Continue baking until no longer pink in the center and the juices run clear, 15 to 20 minutes more. An instant-read thermometer inserted into the center should read at least 165 degrees F (74 degrees C). Discard toothpicks before serving.
