Creamy Mushroom Sauce with Sage Roasted Chicken

A perfect dinner for guests. This crispy roasted chicken cooked with sage butter, then smothered in a creamy, indulgent mushroom sauce, tastes like you’ve been slaving away in the kitchen for hours. When in fact, it doesn’t take a lot of time or effort at all.

I love to serve this chicken dish as part of a roast dinner. The creamy mushroom sauce goes particularly well when you dip roast potatoes into it. Serve some Yorkshire puddings on the side with some steamed vegetables and you have a show-stopping delicious meal that’s perfect for date night or dinner parties.

The mushroom sauce is full of flavour but surprisingly easy to make. The sauce is pretty versatile, you can choose your own mixture of mushrooms to add in but simple closed cup mushrooms will still taste brilliant.

The roasted chicken pieces with crispy skin are quicker to bake that a whole roasted chicken, saving you both time and energy in the kitchen too.

Preparing and Roasting The Chicken

To make the most flavourful, moist roast chicken with crispy skin, we smother each piece with a garlic sage butter and allowing it to marinate before roasting in the oven.

I prefer to use chicken quarters for this recipe, but if you’d prefer, you can use chicken thighs, drumsticks or skin-on chicken breast. You want a cut of chicken with the skin for that roasted crispy chicken skin result. Leaving the skin on the chicken allows the meat to retain the moisture too.

Any variety of bone-in chicken mentioned will still take at least 40 minutes to roast. Chicken breast will be slightly less at around 30 minutes. The reason that chicken pieces with the bone still intact take longer, is due to the bone impacting the heat distribution. However, it does improve the taste and moistness of the meat somewhat, so the extra roasting time is worth it.

Allow your butter to come to room temperature. You want the butter soft but not melted for ease when it comes to spreading it on.

To really incorporate the butter sage flavours into the chicken, score the chicken with a sharp knife. You can then spread the sage butter over them, being sure to allow some to get deep into the scored areas. For best results, I recommend covering the chicken and placing in the fridge to marinate overnight or at least 2 hours.

Roast the chicken uncovered for the crispiest skin.

Check to make sure your chicken is cooked all the way through. The best method is to use a meat thermometer. Pierce the chicken with the thermometer into the thickest part, it should read 75C (165F). Another, although not so accurate method is to cut the chicken quarter and look at the juices, they should run out clear.

Chicken should be removed from the fridge after marinating and allowed to come to room temperature before roasting in the oven.

You can freeze your uncooked chicken portions with the butter for make ahead meals.

How to Make The Mushroom Sauce

For this sauce recipe, I used a simple closed cup white mushroom but you can also use brown chestnut mushrooms or add in a mixture of wild varieties such as Porcini, Oyster, Shitake or Maitake for depth of flavour.

Using a double cream (heavy cream if you’re from the US) makes the sauce thicker and more creamy. If you want to use a lower fat cream, add in a teaspoon of cornflour/cornstarch to a small amount of the cream in a separate bowl, before mixing in the rest of the cream and adding to the recipe.

I don’t recommend adding salt to the sauce as you usually have plenty already added to the chicken stock and cheese. However if you feel the sauce needs more seasoning, wait until you have cooked your mushrooms through before adding it in. The reason for this, is that salt will draw out the liquid in the mushrooms too quickly, making them soggy before they’ve had a chance to brown and cook. Add the salt once the mushrooms are cooked through.

This mushroom sauce is great with steak, if you want an alternative meat. It’ll taste amazing served with this nut roast too, for a vegetarian option.

For a vegetarian mushroom sauce, just replace the chicken stock with a vegetable stock and use a vegetarian parmesan.

You can omit the parmesan if you’d prefer, the sauce still tastes amazing.

You can also omit the wine, just use extra stock. But in this instance, I recommend leaving the parmesan in the recipe for the flavour.

The Sauce can be made ahead and reheating it in a pan doesn’t ruin the flavour at all, just add the cream and cheese before serving to prevent it separating. Cook all the sauce ingredients and then wait to add the cream when you heat it up to use it.

Recipe FAQ

Can I freeze this recipe?

For the chicken, I recommend freezing it uncooked, with the butter spread on.
For the sauce, you can freeze it once made and cooled, but the cream may separate upon reheating. For best results when freezing. Omit the cream and cheese until you reheat the sauce and add them in to warm through, before serving.

Can I use a different herb instead of sage?

You can substitute the sage for rosemary or thyme.

  • Dried Sage can also be used as a substitute to fresh, just use a bit less as it has a more intense flavour.

    Hi Becky,

    I just made this last night! I changed one little thing – I carmelized the onions and mushrooms before adding the leek and garlic. It turned out absolutely fantastic!! Since I only had heavy cream, I thickened the sauce with a little cornstarch and water and it worked like a charm. I’ll definitely make this recipe again, thank you!

      Caramelized onions….Yum! Sounds amazing! x

  2. Hi again, just wondering what happened to the recipe? I was about to make it for this evenings dinner and the recipe is nowhere on the page!

    1. Becky Author says:

      Hi Ashley,

      So sorry there is sometimes a problem with the printable recipe feature, I’m working on finding the problem and fixing it, but you’ll find the recipe live again now.

    This looks utterly delicious, but I do have one question. I live in Canada and have never seen Double Cream anywhere. Is there something else I could use? Thanks!!

    1. Becky Author says:

      Hi Ashley, In Canada I think the closest equivalent would be whipping cream. You may find the sauce is slightly thinner but you can try heating it for a little longer to thicken it. Good luck with the recipe and I’d love to hear how you get on, so please come back and share :) x

      1. Hi Becky,

        thanks so much for getting back to me. I’m definitely going to give it a shot this week. I’ll be sure to let you know how it turns out! :)
