Ingredients
  

  • 2 to 2.5 pounds boneless, skinless chicken breasts or thighs
  • 16 ounces cremini or baby bella mushrooms, sliced
  • 1 medium yellow onion, thinly sliced
  • 3 cloves garlic, minced
  • 1 cup low-sodium chicken broth
  • 1 cup heavy cream or half-and-half (see notes for lighter swaps)
  • 4 ounces cream cheese, softened and cubed
  • 2 tablespoons unsalted butter or olive oil
  • 1 tablespoon Dijon mustard
  • 1 teaspoon dried thyme (or 1 tablespoon fresh, chopped)
  • 1 teaspoon dried parsley (optional)
  • 1 teaspoon onion powder
  • 1/2 teaspoon paprika
  • Salt and freshly ground black pepper
  • 1 to 2 tablespoons cornstarch (optional, for thickening)
  • Fresh parsley or chives, chopped (for garnish)
  • Serving ideas: cooked rice, mashed potatoes, buttered egg noodles, or crusty bread

Method
 

  1. Prep the aromatics: Slice the mushrooms and onion. Mince the garlic. Lightly season the chicken with salt, pepper, and paprika on both sides.
  2. Optional sear for extra flavor: In a skillet over medium-high, melt the butter or heat oil. Sear the chicken 2 to 3 minutes per side until lightly golden. This step adds depth but isn’t required.
  3. Layer the slow cooker: Add onions and mushrooms to the bottom. Sprinkle in garlic, thyme, onion powder, and dried parsley. Place the chicken on top.
  4. Build the sauce base: In a bowl, whisk the chicken broth with Dijon and a pinch of salt and pepper. Pour over the chicken and vegetables.
  5. Cook low and slow: Cover and cook on Low for 4 to 5 hours, or on High for 2.5 to 3.5 hours. Chicken should be tender and reach 165°F internally.
  6. Add the creamy elements: Stir in the cream cheese cubes and heavy cream. Cover and cook on High for 15 to 20 minutes until smooth. Gently stir to fully melt and combine.
  7. Thicken if needed: If you want a thicker sauce, whisk 1 tablespoon cornstarch with 1 tablespoon cold water. Stir into the crockpot and cook 10 more minutes on High until the sauce coats a spoon.
  8. Taste and finish: Adjust salt and pepper. Sprinkle with fresh parsley or chives.
  9. Serve: Spoon chicken and mushroom sauce over rice, mashed potatoes, or noodles. Add a green side like roasted broccoli or a simple salad.
