Ingredients You’ll Need

This Creamy Mushroom Sauce calls for everyday ingredients, each one playing an essential role in building flavor and achieving that dreamy, velvety texture. Don’t skip anything—each part really pulls its weight!

• Brown mushrooms (400g/14oz), sliced: The heart of the sauce—brown mushrooms offer a rich, earthy taste and develop gorgeous color as they brown.
• Heavy cream (⅔ cup): Also labeled thickened cream, this is the secret to creaminess; its higher fat content ensures a silky, stable sauce that won’t break.
• Stock (½ cup): Beef, chicken, or vegetable stock all work well, adding depth and balancing the richness without overpowering the mushrooms.
• Brown onion (¼, thinly sliced): Adds a natural sweetness and ensures an aromatic backbone from the very first sizzle.
• Garlic (2 cloves, minced): The punchy, irresistible core seasoning that brings everything together.
• Dijon mustard (½ tbsp): Gives the sauce a gentle tang to cut through the cream—don’t worry, it won’t overpower!
• Cornstarch (1 tbsp): For that lovely nappe (coating) consistency, it helps the sauce cling to everything.
• Unsalted butter (2 tbsp): The first layer of richness, perfect for sautéing mushrooms and onions.
• Salt and pepper: Essential for seasoning at every stage; black pepper in particular makes the flavors pop.

Variations

The beauty of this Creamy Mushroom Sauce is just how easy it is to tweak; trust me, you can make it your own! Whether you need to accommodate allergies, personal preference, or just the ingredients you have on hand, there’s room to experiment.

• Go Dairy-Free: Use full-fat coconut cream and vegan butter for a surprisingly convincing, plant-based version.
• Add Herbs: Try stirring in fresh thyme, parsley, or even tarragon just before serving for garden-fresh aroma.
• Swap the Mustard: Grainy mustard adds a subtle bite, or, for a milder profile, use a touch of whole-grain or omit it entirely.
• Make It Extra Garlicky: Double (or even triple!) the garlic if you’re a true garlic lover—there’s no such thing as too much flavor here.
• Play With Mushrooms: Incorporate a mix—add some wild or portobello mushrooms to deepen the flavor mix and make things interesting.

How to Make Creamy Mushroom Sauce

Step 1: Sauté Onion and Butter

Start by heating the unsalted butter in a large pan over medium heat. Once it melts and begins to foam, add your thinly sliced brown onion. Sauté for about 1.5 minutes, stirring occasionally, just until the onion becomes tender and smells sweet—it should already start layering in flavor that’ll make the sauce unforgettable!

Step 2: Brown the Mushrooms

Toss in all your sliced mushrooms and turn the heat to medium-high. Give them a good toss every minute or so, but let them sit long enough to brown. You want those golden, caramelized edges! Season with salt and pepper about halfway through. This step takes about 8 minutes and creates so much of that signature flavor (and gorgeous color) for the Creamy Mushroom Sauce.

Step 3: Add Garlic

Reduce the heat to medium-low. Sprinkle in your minced garlic and stir it through the mushrooms for about a minute. As soon as the aroma hits your nose, the garlic is ready—don’t let it brown or burn!

Step 4: Deglaze with Stock

Pour in your chosen stock (beef, chicken, or veg—whatever you love). Use a wooden spoon to scrape up all the golden goodness stuck to the pan. Let the stock bubble away for about 1.5 minutes, reducing by half and deepening the mushroom flavor as it thickens.

Step 5: Add the Cream and Dijon

Lower the heat to its gentlest setting—this keeps your cream luxuriously smooth. Stir in the heavy cream and dijon mustard. Give it a good mix and season to taste. Let everything get cozy, but don’t let it bubble up too much—a gentle simmer is perfect for this Creamy Mushroom Sauce.

Step 6: Thicken and Finish

In a small bowl, combine 1 tablespoon cornstarch with 2 tablespoons cold water to make a slurry. Stir this into the sauce and keep simmering for about 3 minutes, stirring regularly. The sauce will transform before your eyes, going from creamy to utterly luscious. Once it coats your spoon, you’re done!

How to Serve Creamy Mushroom Sauce

Garnishes

For a fresh, beautiful final touch, shower the finished Creamy Mushroom Sauce with finely chopped flat-leaf parsley or a light sprinkle of fresh thyme leaves. Both add a pop of color and subtle herbal lift, and make your sauce look every bit as delicious as it tastes.

Side Dishes

This sauce is a natural best friend to steak or roast chicken, but don’t stop there—it’s phenomenal over pillowy mashed potatoes, egg noodles, or a bed of rice. You can even spoon it over grilled asparagus, broccoli, or roasted root veggies for an elevated vegetarian meal.

Creative Ways to Present

For a dinner party wow-factor, serve the Creamy Mushroom Sauce in a small pitcher or gravy boat so guests can help themselves. Or, try mixing it with cooked pasta and sauteed spinach for an instant creamy mushroom pasta. Swirl it onto a plate before topping with seared chicken for that dramatic, restaurant-style look!

Make Ahead and Storage

Storing Leftovers

Keep any leftover sauce refrigerated in an airtight container for up to 3 days. As it sits, the sauce will naturally thicken—don’t worry, it’ll loosen back up beautifully on reheating with a splash of water.

Freezing

I don’t recommend freezing Creamy Mushroom Sauce. Dairy-based sauces tend to split when thawed, leading to a grainy or separated texture—especially if you’ve used light cream. It will still taste fine, but won’t have that signature silkiness.

Reheating

To reheat, pour the sauce into a pan over low heat, stirring gently. Add a splash or two of water if needed to restore the sauce’s original consistency, and stir constantly so the cornstarch doesn’t clump. Avoid boiling, especially with light cream in the mix.
