Instructions

1. 1

   Prepare the aromatics

   Peel and finely chop the onion. Peel and mince the garlic, then chop the parsley or thyme and set it aside.

2. 2

   Slice the mushrooms

   Rinse the mushrooms to remove any dirt, trim their stems and slice them thinly.

3. 3

   Soften the onion

   Melt the butter in a frying pan over medium heat. Add the onion and sauté for about 2 minutes, until softened, then add the garlic and cook for 1 minute.

4. 4

   Cook the mushrooms

   Add the mushrooms and cook over medium-high heat for about 5 minutes, until they have softened and their liquid has evaporated.

5. 5

   Simmer the liquid

   Pour in the wine, stock or water, lower the heat and simmer for 5 minutes.

6. 6

   Add cream and seasoning

   Stir in the cream and season with salt and black pepper. If using cheese, sprinkle it in now.

7. 7

   Thicken the sauce

   Simmer for another 2–3 minutes, stirring occasionally as the sauce thickens. Keep it from boiling, as the cream may split.

8. 8

   Finish and serve

   When the sauce reaches your preferred thickness, stir in the chopped parsley and serve straight away. If it is too thick, loosen it with a few spoonfuls of water, milk or stock.

What is creamy mushroom sauce?

This is a Polish-style mushroom sauce: sliced mushrooms are cooked with onion and garlic, then simmered with a liquid and finished with cream. Creamy mushroom sauces are served in many cuisines, and this version is suited to a range of familiar mains as well as traditional Polish dishes.

The method builds flavour by cooking the mushrooms until their released liquid has evaporated before adding the wine, stock or water. Cream gives the sauce its richness, while optional grated cheese adds another savoury note.

Nutrition and macros by portion

The nutrition label shows one serving as written: 226 calories, 10g protein, 10g carbs, 15g fat.

The mushrooms provide some of the carbohydrates, while the cream, butter and optional cheese contribute much of the fat; the mushrooms and cheese also contribute protein. Pair a serving with a source of fibre such as vegetables, or serve it over pasta if you want a more substantial plate.

Choosing the ingredients

Mushrooms: Brown button mushrooms have a deeper flavour, but white mushrooms or fresh wild mushrooms can be used instead. Slice them evenly so they cook at a similar rate.

Cooking liquid: Dry white wine gives a different flavour from stock or water; use whichever suits the dish you are serving. The cream and optional cheese bring richness, so the sauce can be made without cheese if preferred.

Herbs: Parsley keeps the finish fresh, while thyme gives it a more aromatic edge. The recipe adds the herbs at the end.

Get the mushrooms ready

Rinse the mushrooms to remove dirt, then trim the stems and slice them thinly. Let them cook until their liquid has evaporated and the slices have softened before adding the next liquid.

Avoid rushing this stage: the recipe relies on that evaporation before the sauce is built. If liquid remains in the pan, continue cooking until it has gone.

Keep the cream smooth

Once the cream goes in, keep the sauce at a gentle simmer rather than letting it boil. Stir occasionally as it cooks for the final 2–3 minutes, watching for it to thicken.

Cheese is optional and is stirred in with the cream. If the finished sauce becomes too thick, add a few spoonfuls of water, milk or stock.

What to serve it with

The sauce works with chicken, steak or salmon, and it can be spooned over pasta. It also suits a variety of traditional Polish dishes.

Choose a main that benefits from a creamy, savoury accompaniment. A simple vegetable side can add freshness and contrast to the rich sauce.

Timing and doneness

The listed total time is 15 minutes, with several short cooking stages in sequence. Chopping the onion, garlic, herbs and mushrooms before heating the pan helps keep the cooking moving.

The mushrooms are ready for the liquid when softened and their liquid has evaporated. The sauce is ready when it has thickened to your liking after its final gentle simmer.

Recipe notes & tips

• Slice the mushrooms thinly so they soften evenly.
• Cook off the mushroom liquid before adding the wine, stock or water.
• Choose parsley or thyme according to the flavour you want.
• Keep the sauce at a gentle simmer after adding the cream.
• Loosen a thick sauce with a few spoonfuls of water, milk or stock.

Variations

• Use shallots: Replace the onion with the listed shallots for a milder allium flavour.
• Try white mushrooms: Use regular white mushrooms in place of brown button mushrooms.
• Use wild mushrooms: Substitute fresh wild mushrooms for a different mushroom flavour.
• Change the liquid: Choose stock or water instead of dry white wine.
• Add cheese: Stir in finely grated Gouda, Cheddar or Polish bursztyn for a cheesier sauce.
• Choose thyme: Use fresh thyme instead of parsley for a more aromatic finish.

Common mistakes to avoid

• Adding liquid too soon: Cook until the mushrooms' released liquid has evaporated first.
• Boiling the cream: Keep the sauce at a gentle simmer to reduce the risk of it splitting.
• Uneven slices: Cut the mushrooms thinly and evenly so they soften at a similar rate.
• Over-thickening: Stir in a few spoonfuls of water, milk or stock to loosen the sauce.
• Skipping the final stir: Stir occasionally during the last 2–3 minutes so the sauce thickens evenly.

How to store

Refrigerate leftover sauce in a covered container and use within 2 days. Reheat gently in a pan, stirring; add a splash of water, milk or stock if it has thickened.
