Keto Mushrooms in Cream Sauce
Restaurant creamed mushrooms are usually thickened with flour and sit heavy in the stomach. The keto version skips the flour and still turns out creamy: reduced cream and the mushrooms' own juices form a glossy sauce. Per serving: 3 g net carbs, 22 g fat, 6 g protein. Pairs with steak, chicken breast, an unbreaded schnitzel, or simply a fried egg.

Tips for foolproof creamed mushrooms
- Clean mushrooms dry, never wash them.
- Preheat the pan properly and cook in a single layer.
- Only add salt once the mushrooms have taken on color.
- Reduce the cream gently, do not boil hard, or it will split.
- Stir in the parsley right at the end so color and aroma stay fresh.
Why don't creamed mushrooms need flour?
Mushrooms are around 90 percent water. Sear them hot and in a thin layer and that water evaporates instead of diluting the sauce. Reduced cream is naturally thick: the fat-rich protein network sets once it is cooked down to about half its volume, no starch required. A classic roux would only add 10 to 15 g of extra carbs per serving without contributing to flavor. A hard sear matters more here than any thickener.

How can I vary the creamed mushrooms?
With cognac: deglaze with 2 tbsp cognac right before the cream, flambéed or simply reduced, for a restaurant-style depth. With thyme: fry 1 sprig of fresh thyme together with the mushrooms, great with braised meats and beef. Mixed mushrooms: combine 250 g white mushrooms with 250 g chanterelles or porcini, a little pricier but more aromatic. With bacon: render 80 g diced bacon first, then sear the mushrooms in the bacon fat for a rustic version. With cream cheese: swap 50 ml of the cream for 50 g cream cheese for a thicker, cheesier sauce, perfect with pasta substitutes like konjac noodles.

FAQ
Why do my mushrooms turn watery?
Two reasons: the pan is too cool or too crowded. Mushrooms need space and heat. Better to sear them in two batches than all at once. And only salt them once the surface has color, otherwise the cells open up and the water rushes out.
Can I prepare the sauce ahead?
Mushrooms in cream sauce keep for two days in the fridge. When reheating in the pan, stir in a splash of fresh cream if the fat has separated. The microwave works too, but the mushrooms get slightly rubbery.
Which other mushrooms work?
Chanterelles, porcini, king oyster mushrooms or shiitake, any mushroom with a firm structure works well. Very wet mushrooms like oyster mushrooms need longer to sear properly.
Does this side fit a keto weight-loss plan?
Yes. It brings 3 g of net carbs and a lot of volume for 260 kcal, so it fills the plate cheaply. Almost all the calories are in the butter and cream, so reducing the cream and stretching with mushroom juices works well.
