Ingredients You’ll Need

This Creamy Mushroom Sauce Recipe relies on a handful of simple yet powerful ingredients that work together to create its lush texture and rich flavor. Each component is essential, from the earthy mushrooms to the tangy dijon mustard, creating layers of taste and a luscious, silky finish.

Brown mushrooms (400 g / 14 oz, sliced): The star of the sauce, bringing umami depth and a meaty texture when caramelized.
Heavy cream (⅔ cup): Also known as thickened cream, this adds the signature rich, creamy body to the sauce.
Stock (½ cup): Beef, chicken, or vegetable stock all work wonderfully to deglaze the pan and add savory complexity.
Brown onion (¼, thinly sliced): Provides sweetness and a subtle bite, softening perfectly when cooked.
Garlic (2 cloves, minced): Just enough to infuse the sauce with aromatic warmth without overpowering.
Dijon mustard (½ tbsp): Offers a gentle tang that brightens the cream and balances richness.
Cornstarch (1 tbsp): Mixed with water to thicken the sauce to silky, spoonable perfection.
Unsalted butter (2 tbsp): For sautéing the onions and mushrooms, adding luxury and a golden hue.
Salt and pepper: To season at different stages and bring all flavors into harmony.

How to Make Creamy Mushroom Sauce Recipe

Step 1: Sauté the onions

Start by melting the unsalted butter in a large pan over medium heat. Add the thinly sliced brown onions and gently cook for about a minute and a half, until they become soft and translucent. This step lays the flavorful foundation, releasing natural sweetness that pairs beautifully with the mushrooms.

Step 2: Caramelize the mushrooms and onions

Toss in the sliced brown mushrooms and increase the heat to medium-high. Stir frequently, allowing the mushrooms and onions to caramelize evenly. This process takes about eight minutes and is crucial for developing their deep, savory flavor—season with salt and pepper halfway to enhance the natural taste.

Step 3: Add the garlic

Turn the heat down to medium-low and stir in the minced garlic. Cook it for about one minute until it’s fragrant—this quick step infuses the sauce with a gentle, warming aroma that complements the richness ahead.

Step 4: Deglaze with stock

Pour in your choice of stock to deglaze the pan, using it to lift all those delicious browned bits stuck to the bottom. Let the liquid reduce by half, roughly a minute and a half, concentrating the flavors and adding a savory depth.

Step 5: Incorporate cream and dijon mustard

Lower the heat to its gentlest setting and gently stir in the heavy cream and dijon mustard. Season with salt and pepper to taste. The cream introduces the luscious texture, while the dijon adds a subtle tang that cuts through the richness, making every bite perfectly balanced.

Step 6: Thicken the sauce

Mix the cornstarch with two tablespoons of cold water until smooth, then pour this mixture into the pan. Allow the sauce to simmer for about three minutes, stirring regularly to achieve a silky, thick consistency that clings beautifully to any dish.

Step 7: Final touches and serving

Finish with a sprinkle of finely diced fresh parsley or fresh thyme leaves to add a burst of color and fragrant brightness. This small touch brings freshness and elevates the sauce’s presentation, making it as delightful to look at as it is to eat.

Make Ahead and Storage

Storing Leftovers

Allow the sauce to cool completely before transferring it to an airtight container. It will keep well in the refrigerator for up to three days, making it a fantastic option for meal prep or quick flavor boosts during the week.

Freezing

You can freeze this Creamy Mushroom Sauce Recipe for up to two months. Use a freezer-safe container, leaving some space for expansion. Keep in mind that cream sauces might separate slightly after freezing, but gentle reheating and whisking usually restore the perfect texture.

Reheating

Reheat the sauce gently over low heat on the stove, stirring frequently to prevent sticking and to bring back its silky consistency. If it’s too thick, add a splash of stock or cream to loosen it up without compromising flavor.

FAQs

Can I use other types of mushrooms for this sauce?

Absolutely! While brown mushrooms offer a great balance of flavor and texture, you can experiment with cremini, shiitake, or even porcini for a more intense earthy note. Just adjust cooking times slightly based on the mushroom’s firmness.

Is there a dairy-free option for the cream?

Yes! You can substitute the heavy cream with coconut cream or a cashew-based cream substitute. Keep in mind the flavor will change slightly, but it will still be creamy and delicious.

How thick should the sauce be?

The sauce should be thick enough to coat the back of a spoon, but still pourable. The cornstarch-thickening step ensures this luscious texture, so don’t skip it for the best results.

Can I make the sauce ahead of time?

Definitely. The sauce holds up well in the fridge and even tastes better the next day as the flavors meld. Just reheat gently before serving and stir in a little extra cream if needed to refresh its texture.

What dishes pair best with this creamy mushroom sauce?

This sauce pairs wonderfully with steak, chicken, pasta, and roasted vegetables. It’s versatile enough to dress up simple meals while bringing comforting richness that’s hard to resist.
