Why I Love This Meal

  • Set it and forget it – If you have a long day ahead of you, throw these few ingredients in the slow cooker in the morning and end your day with a comforting meal that takes very little work.
  • Very little prep – This easy Slow Cooker Mushroom Chicken only takes a few minutes to prep and you can let it cook low and slow all day.
  • That creamy sauce – The ultra-creamy sauce is made from condensed cream of mushroom soup, sour cream, and mushrooms. It is so rich and satisfying you’re going to want to drink it up!


The mushroom sauce is super simple but yields an incredible flavor when cooked with the chicken. It’s just condensed cream of mushroom soup, sour cream, chicken broth, and minced garlic that is poured over the seasoned chicken and cooks together to form a thick, creamy, delicious sauce.

  • Chicken Breasts – 2 pounds or about 3 large chicken breasts is all you need. Both should be boneless and skinless.
  • Seasoning – Onion powder, paprika, salt, and black pepper. I use this simple seasoning on just about everything.
  • Sour Cream – A full-fat sour cream will give you the best flavor and make your gravy extra creamy. You can also use low-fat if you prefer.
  • Condensed Cream of Mushroom Soup – Find this in the soup aisle of the grocery store. Do not add any milk or water to the cream soup.
  • Chicken Broth – I always opt for a low-sodium variety because I prefer to control the salt content myself.
  • Minced Garlic – Fresh or jarred works great.
  • Mushrooms – Easy to find in the produce section. I usually buy pre-sliced to keep it easy. Make sure to wash them first to remove any dirt.

How To Make Slow Cooker Mushroom Chicken

Get a detailed list of ingredients & instructions in the recipe card below.

  1. Season the chicken. Sprinkle both sides of the chicken with salt, pepper, paprika, and onion powder.
  2. Make the mushroom sauce. In a medium bowl, mix together the cream of mushroom soup, chicken broth, and minced garlic. Stir in the sliced mushrooms until evenly distributed.
  3. Slow cook it. Lay the seasoned chicken into the slow cooker and pour the mushroom sauce over the top. Cover and cook on LOW for 6 hours or HIGH for 4 hours. Mix the sour cream into the sauce until it is combined.
  4. Serve it. I like to serve the mushroom chicken over egg noodles but it is also great over rice or mashed potatoes.

How To Thicken Mushroom Gravy

If the mushroom sauce is too thin for your taste, add a little bit of cornstarch slurry:

  • In a small bowl, whisk together 1 tablespoon of cornstarch and 1-2 tablespoons of water.
  • Pour this into the crockpot and give it a stir. Cover and continue cooking on low for 10 minutes or until thickened. It should thicken pretty quickly.

Make Ahead, Storage, and Freezer Tips

Make Ahead: Because this dish only takes minutes to throw together, other than putting it all into the slow cooker, there isn’t much to do ahead of time.

Storing Leftovers: This mushroom chicken serves 4-6 so if you have leftovers, store them in an airtight container in the fridge for up to 3 days. Reheat on the stovetop.

Freezing: You can freeze prepared mushroom chicken in a freezer bag or freezer safe container for up to a month. To thaw the frozen portion, you can put it back in the slow cooker for a couple hours on low to come to temperature.


Which type of chicken should I use?

I use boneless skinless chicken breasts. If you are short on time, you can butterfly the breasts and they will cook in 2-3 hours on HIGH.

Should I use fresh mushrooms?

I use fresh sliced mushrooms. You can find them in the produce section, pre-washed and pre-sliced which make them really convenient. You can also use canned mushrooms if that’s what you have on hand or prefer.

What do you serve with mushroom chicken?

I like to serve this mushroom chicken over egg noodles, rice, or mashed potatoes. It’s also really tasty over German Spaetzle. I always pair it with a vegetable side like green beans, broccoli, or carrots.

Helpful Tips

  • For evenly cooked chicken, it’s important to ensure the chicken breasts are roughly the same size and thickness. Gently pound them if needed.
  • I highly recommend using fresh mushrooms. While you can use canned mushrooms, they won’t taste the same.
  • Do not overcook the chicken – Chicken breasts are notorious for being easy to overcook. Do not cook longer than suggested.
