Creamy Tarragon Mushroom Sauce

Mushrooms and tarragon are a classic flavour harmony. The earthy, umami-rich taste of mushrooms provides an excellent base, lifted by the freshness of tarragon. This sauce is thick, chunky, and filling, so it can be not just a side but even the star of a meal, for example with tagliatelle.

Instructions

1

Clean the mushrooms (don't soak, just wipe!), and slice them. Finely chop the onion and garlic.

Tip: Mushrooms have a sponge-like structure; if washed in water, they soak it up and won't fry nicely.
2

Heat the butter in a large frying pan over medium heat. Add the onion and sweat until soft.

Tip: The onion is ready when translucent and soft, but not yet brown.
3

Increase heat to high and add the mushrooms. Fry until they release liquid, this evaporates, and the mushrooms start 'squeaking' and browning.

Tip: High heat is key for caramelisation, which deepens the mushroom flavour.
4

If using wine, pour it in now and boil it away completely. If not, skip this step.

Tip: Wine acidity helps dissolve the browned bits stuck to the pan (deglazing).
5

Add crushed garlic and tarragon, stir (approx. 30 sec). Pour in the cream, season with salt and pepper.

Tip: Give the garlic only a short cooking time so it doesn't become bitter.
6

Cook the sauce for a few minutes until it thickens. Finally, stir in the lemon juice.

Tip: Lemon juice acidity 'wakes up' the heavy, creamy mushroom flavours.

Recipe FAQ

Why did the mushrooms get watery?
Mushrooms contain a lot of water. If you put too many mushrooms in the pan at once, the temperature drops and they start steaming instead of frying.
What mushrooms should I use?
Brown chestnut mushrooms are tastier than white, but mixing with wild mushrooms makes it truly special.
