Chicken breast in creamy mushroom and butternut squash sauce

25 October 2018 | Last Updated: 10 March 2021 By Aleksandra

Quick delicious autumn dinner. Juicy and moist chicken breast in creamy mushroom sauce with butternut squash. The preparation is very simple and the dish full of flavor. This recipe can be made two ways – either with raw butternut squash or with pumpkin puree. Serve it with potatoes or with pasta!

Chicken breast in creamy mushroom and butternut squash sauce


  • Chicken – I used chicken breast but also boneless chicken thighs can be used (they may require a little longer cooking time). Turkey breast can also be used.
  • Butternut squash – you can use any type of squash or pumpkin. You can also use raw pumpkin or pumpkin puree. This sauce is also really amazing with pumpkin puree – it thickens the sauce naturally. I also tested it with roasted pumpkin chunks, but I like it much better with either raw pumpkin or pumpkin puree. Cooking time may slightly vary depending on the pumpkin/squash type.
  • Mushrooms – I used cremini mushrooms (brown mushrooms) but also easier-to-get white button mushrooms can be used. Cremini mushrooms taste a little better.
  • Cream – the sauce is a bit lightened up, because I used sour cream instead of heavy cream, as I usually do. But it‘s slightly sour and tangy and works here perfectly and balances rather heavy mushrooms and pumpkin. You can easily swap it for heavy cream/heavy whipping cream but I really like the tang of the sour cream. When using pumpkin puree I would add heavy cream though.

Chicken breast in creamy mushroom and butternut squash sauce – step by step:

STEP 1: Cut the chicken breast into equal-sized pieces. Season with salt and pepper.

STEP 2: Cut the mushroom into slices, butternut squash into small cubes. Dice the onion and finely chop the garlic.

STEP 3: Cook the chicken pieces on both sides until golden. Chicken doesn’t have to be cooked through. Transfer to a plate.

STEP 4: Cook the mushroom, butternut squash, onion, and garlic.

STEP 5: Add the cream, broth, and nutmeg. Simmer for a couple of minutes until the sauce thickens.

STEP 6: Add the chicken pieces back to the pan. Cook until cooked through. Season with salt and pepper to taste and enjoy!


  • The key to success is to cook the meat very briefly. Cooking the delicate chicken breast for too long results in dry and tasteless meat. Cook the meat until golden, turn, fry very briefly and remove from the pan. The meat will be cooked through later in the sauce.
  • Don’t stir the mushroom right away. Wait a little allowing them to brown. This will provide lots of flavor.

-> 2 small chicken breasts, about 300g / 10.5 oz

    -> for the sauce:

    • 2 tablespoons frying oil
    • 200 g / 7 oz cremini mushrooms
    • 120 g / 4.2 oz butternut squash without skin and seeds OR 2/3 cup pumpkin puree
    • 1 small onion or 2 shallots
    • 2 cloves garlic
    • ½ cup sour cream 12% or heavy cream 30-36%, 120 ml
    • ½ cup broth vegetable/chicken broth/water, 120 ml
    • ¼ teaspoon nutmeg
    • 1 tablespoon chopped dill
    • salt and pepper to taste

    to serve: potatoes, green beans


      • Cut the chicken breasts into 3 equal pieces (in half crosswise, then the thicker half again in half, lengthwise). You can also pound it lightly to an even thickness (it will cook evenly and be juicy. Season to taste with salt and pepper.
      • Cut the butternut squash into very small cubes, about 0.5 cm / 1/4 inch. You can also grate it on the big holes of the grater, but I think it looks more appetizing when you cut it in cubes. If you're using pumpkin puree add it later along with the broth and cream.
      • Cut the mushrooms into thick, 0.5 mm / 1/4 inch slices.
      • Chop finely the shallots (or onion) and garlic.
      • Heat the oil in a large frying pan over high heat, add in the chicken pieces. Cook on one side for about 3 minutes, until golden, turn over and cook for a minute. Be careful not to overcook the meat, or it will be tough. Remove from the pan, it should be slightly pink in the middle (it will be cooked through later in the sauce) or no longer pink. Transfer on a plate.
      • Add the mushrooms and butternut squash to the pan, spread them evenly. Cook over high heat for about 3 minutes, don’t stir (!). When they are sightly browned at the bottom – stir, then add the onion with garlic. Reduce the heat to medium-low. Cook, stirring from time to time for about 4-5 minutes.
      • Pour in the cream and broth (and pumpkin puree if using), season with nutmeg and cook over medium-low heat for a few minutes, until the sauce thickens a bit. Don‘t worry if the sour cream breaks into small clumps – the sauce will be smooth again after cooking for a few minutes.
      • Add the chicken back to the pan, cook until cooked through.
      • Remove from the heat, season with salt and pepper, stir in chopped dill.
      • Serve with potatoes and optionally with other vegetables, like cooked green beans.
      • Enjoy!


      • Butternut squash substitute: you can use other sqash type or pumpkin. Raw sqash can be used or pumpkin puree. Both versions are delicious.
      • You can also serve this sauce with pasta.
      • Sour cream substitute: heavy cream or heavy whipping cream.
      • If your using raw squash and not pumpkin puree you can drench the chicken in flour prior to cooking it, to thicken the sauce (totally optional).
      • Cooking times may vary, depending on the stovetop type.
      • Calories count = 1/2 of the recipe, not including the pictured potatoes and green beans (this is only an estimate).

      I made this recipe, when I googled the ingredients I had available, mushrooms, butternut squash , and chicken breast. I changed it up. I dredged the chicken in flour, salt and pepper. I cooked the chicken with EVOO and Butter. then followed the rest of the recipe as written. Used onion since i didn’t have shallots. It was so delicious. Thank you.
