I’ve been making a different version of mushroom sauce at just about every restaurant I’ve ever worked in. Most restaurant recipes start with a high carb gravy powder, with a small amount of cream and mushrooms added in – that’s the kind of sauce we’d rather avoid.

We recommend making your keto mushroom sauce fresh, but the leftover sauce can be stored in the fridge for up to 3 day days.

Reheat the sauce over low heat, as too high heat will cause it to split.

    This sauce was insanely good! This is a keeper even if you are not doing keto, It is very rich and flavourful so a little goes a long way, I served over pork tenderloin medallions but would be really good with salmon or chicken, I didn’t have tarragon so used a pinch of fennel seed and some fresh parsley,
