Ingredients

  • 4 boneless, skinless chicken breasts
  • 8 ounces (225 g) mushrooms, sliced
  • 1 medium onion, chopped
  • 3 cloves garlic, minced
  • 1 cup (240 ml) chicken broth
  • 1 cup (240 ml) heavy cream
  • 1 tablespoon Dijon mustard
  • 1 teaspoon dried thyme
  • 1 teaspoon salt, or to taste
  • 1/2 teaspoon black pepper, or to taste
  • Fresh parsley, chopped (for garnish)

Instructions

  1. Place the chicken breasts in a single layer at the bottom of the slow cooker.
  2. Add the sliced mushrooms, chopped onion, and minced garlic evenly over the chicken.
  3. In a medium bowl, whisk together the chicken broth, heavy cream, Dijon mustard, dried thyme, salt, and pepper until smooth and well combined.
  4. Pour the creamy mixture over the chicken and vegetables in the slow cooker, making sure everything is mostly submerged.
  5. Cover and cook on LOW for 6–7 hours or on HIGH for 3–4 hours, until the chicken is cooked through and very tender.
  6. Once cooked, carefully remove the chicken breasts from the slow cooker and set them on a plate. Stir the sauce well to fully combine the mushrooms, onions, and juices.
  7. Taste the sauce and adjust seasoning with additional salt and pepper if needed.
  8. Return the chicken to the slow cooker, turning to coat it in the creamy mushroom sauce. Let it sit on the WARM setting for about 10 minutes to absorb the flavors.
  9. Serve hot, spooning plenty of mushroom sauce over each piece of chicken, and garnish with freshly chopped parsley.

Variation

  1. Use boneless, skinless chicken thighs instead of breasts for an extra-juicy result; cooking time stays about the same.
  2. Swap heavy cream for half-and-half and stir in 2–3 tablespoons grated Parmesan at the end for a lighter, cheesy twist.
  3. Make it a complete one-pot meal by adding 2 cups baby spinach and 1 cup frozen peas during the last 20–30 minutes of cooking.

Cooking Notes

  1. Chicken is done when it reaches an internal temperature of 165°F (74°C); it should be very tender and easy to slice or shred.
  2. Avoid lifting the lid frequently while cooking each peek can add 20–30 minutes to the total cook time.
  3. If the sauce looks slightly separated near the end, a good whisk or stir usually brings it back together into a creamy consistency.

Serving Suggestions

  1. Serve over mashed potatoes, rice, or egg noodles to soak up every drop of the creamy mushroom sauce.
  2. Pair with steamed green beans, roasted broccoli, or a simple side salad for balance and freshness.
  3. Add a crusty loaf of bread or garlic bread on the side for dipping into the extra sauce.

Tips

  • Slice mushrooms evenly so they cook at the same rate and stay tender but not mushy.
  • Season the chicken lightly with salt and pepper before placing it in the slow cooker for an extra layer of flavor.
  • Let leftovers cool completely, then store in an airtight container in the refrigerator for up to 3–4 days; reheat gently on the stovetop over low heat or in the microwave.

Frequently Asked Questions

  1. Can I use frozen chicken?
    It’s safest to use fully thawed chicken in the slow cooker so it reaches a safe temperature quickly and cooks evenly.
  2. Can I make this dairy-free?
    Yes, use full-fat coconut milk in place of heavy cream and ensure your broth is dairy-free.
  3. How can I thicken the sauce more?
    Stir in a cornstarch slurry (1 tablespoon cornstarch mixed with 1 tablespoon cold water) and cook on HIGH for 10–15 minutes until thickened.
  4. Can I prep this ahead of time?
    You can add all ingredients (except cream) to a freezer bag and freeze. Thaw overnight, add to the slow cooker with cream, and cook as directed.

Notes

  • For a thicker sauce, remove the chicken at the end of cooking, whisk 1–2 teaspoons cornstarch with a splash of cold water, stir into the sauce, and cook on HIGH for 10–15 minutes.
  • If your slow cooker runs hot, check the chicken on the earlier side of the time range to avoid overcooking.
  • Use low-sodium chicken broth to better control the salt level, especially if serving with salty sides like Parmesan mashed potatoes.
