Alrighty, this is an easy keto recipe you are going to love. Making a keto creamy mushroom sauce is not hard. It takes no fancy ingredients but I do have a couple of variations to suit your tastes.

I used very simple button mushrooms in this recipe. However, you can add some rehydrated forest mushroom mix, portobello, pine, or swiss brown mushrooms. Whatever mushrooms you prefer you can use.

Cream and butter – I have used a thickened (or heavy) cream for the mushroom sauce recipe. However, for a dairy-free option you can swap butter for avocado oil and cream for beef broth (or coconut cream) if preferred. This is perfect for a paleo or keto vegan mushroom sauce option too. Parmesan can also be swapped for nutritional yeast flakes for a “cheesy” flavour.

Fresh herbs – while I have used fresh parsley and fresh thyme, tarragon or dill are perfect herbs that go with mushrooms too.

Variations: Add Worcestershire sauce (when sauteeing mushrooms) and Dijon mustard for added umami. Omit the cream and use beef broth or chicken broth for an easy keto mushroom gravy. If you need to thicken the gravy (or sauce) add a 1/4 teaspoon of xanthan gum or glucomannan powder).

FAQs and Tips

What mushrooms are best in a creamy mushroom sauce? Even though this recipe uses white button mushrooms any mushrooms of choice, or a combination can be used. Portobello, pine, oyster or brown mushrooms to name a few.

Can the sauce be frozen? I wouldn’t recommend it although it can be. If you do freeze it please reheat over a gentle heat careful not to split the cream.

Can I make this sauce into a keto mushroom gravy? Yes, you can. By using large brown mushrooms, which will add a richer deeper flavour, you can make this recipe into more of a keto mushroom gravy.
