Ingredients for cream of mushroom soup sauce
Rich umami mushrooms, velvety cream, and aromatic herbs—everything you need for restaurant-quality cream of mushroom sauce.
| Ingredient | Amount | Notes |
|---|---|---|
| White Button Mushrooms 🍄 | 1 ½ lb | Sliced into even pieces |
| Unsalted Butter 🧈 | ½ cup | Cold, cubed for roux |
| All-Purpose Flour 🌾 | ½ cup | White gold for thickening |
| Shallots 🧅 | 2 whole | Minced for aromatic base |
| Garlic Cloves 🧄 | 3 cloves | Finely minced for depth |
| Fresh Thyme Leaves 🌿 | ¼ cup | Or 1 tbsp dried thyme |
| Heavy Cream 🥛 | 1 ½ cups | Full-fat for richness |
| Chicken Broth 💧 | 2 cups | Low-sodium preferred |
| Dry Sherry 🍷 | ½ cup | Or substitute with white wine |
| Salt 🧂 | 1 tsp | Diamond Crystal preferred |
| Ground Black Pepper 🌶️ | ½ tsp | Freshly cracked |
The mushrooms are the soul of this sauce. White buttons work perfectly, but cremini or shiitake add even deeper flavor. Slice them uniformly so they cook evenly—no one wants mushy bits. For the best quality, grab fresh mushrooms from Whole Foods or your local market. If you're using dried mushrooms, soak them first and use the soaking liquid in the sauce. The butter and flour combo creates that signature roux—don't rush this step. A slow cook over medium heat prevents burning, which would turn your sauce bitter.
No sherry? Dry white wine or extra chicken broth keeps the sauce balanced. Fresh thyme is ideal, but dried thyme at one-third the amount works in a pinch. For a dairy-free version, swap heavy cream for coconut milk (use full-fat for best texture). The shallots and garlic can be pre-minced to save time—just don't skip them. They're what gives the sauce that subtle, complex sweetness. If you're making this ahead, the flavor actually improves as it sits, so don't hesitate to prep early.
This sauce keeps beautifully. Store leftovers in an airtight container in the fridge for up to 5 days, or freeze for 3 months. To reheat, warm gently on the stove and stir occasionally—never let it boil. The texture will thicken slightly as it cools, so add a splash of warm broth if it gets too stiff. I like to portion it into small jars for easy use throughout the week. Perfect for drizzling over mashed potatoes, pairing with roasted chicken, or even using as a base for creamy pasta dishes.

Step-by-step instructions for cream of mushroom soup sauce
Here's how to craft a luxurious, velvety mushroom sauce with deep umami flavor and perfect texture.
Sauté Aromatics and Mushrooms Until Golden
Heat a large Dutch oven over medium heat. Add the cubed unsalted butter and let it melt completely, watching for golden bubbles to form along the edges. This is your signal to add the minced shallots and garlic cloves, cooking them for 2-3 minutes until they become translucent and fragrant.
Increase heat to medium-high and add the sliced white button mushrooms. Cook them undisturbed for 5 minutes to develop a golden crust on the bottom. Stir occasionally, breaking up any large pieces as they release their moisture. You'll know they're ready when the mushrooms have softened and released their juices, creating a rich, earthy base for your sauce.
Build the Roux for Thickening
Reduce heat to medium-low and sprinkle the all-purpose flour evenly over the mushrooms. Stir constantly for 2-3 minutes until the mixture forms a smooth, pale roux. This step is crucial—it removes the raw flour taste while creating the velvety texture that defines cream of mushroom soup.
Watch the color carefully. You want it to be a light golden hue, not brown. If it starts to darken too quickly, reduce the heat slightly. The roux should coat the back of a spoon smoothly when you lift it from the pot. This ensures your sauce will thicken beautifully without becoming gluey.
Deglaze and Simmer the Base
Pour in the dry sherry and scrape the bottom of the pot vigorously with a wooden spoon to release all the flavorful browned bits. Let the mixture simmer for 3-4 minutes until the alcohol smell dissipates completely. This step adds depth and complexity to your sauce.
Gradually whisk in the chicken broth, making sure to incorporate it slowly to prevent lumps. Add the fresh thyme leaves and bring the mixture to a gentle simmer. Let it cook uncovered for 10-12 minutes, stirring occasionally, until the liquid has reduced by about one-third. You'll notice the sauce becoming thicker and more concentrated as it develops its rich mushroom flavor.
Finish with Cream for Velvety Texture
Reduce heat to low and gradually whisk in the heavy cream. Let the sauce simmer gently for 5-7 minutes, stirring occasionally. The cream will help smooth out the texture while adding luxurious richness. Taste and adjust seasoning with the salt and ground black pepper—this is where you can really refine the flavor balance.
Continue simmering until the sauce reaches your desired consistency. It should coat the back of a spoon smoothly but still be pourable. For an extra-smooth finish, use an immersion blender to purée the sauce until completely silky. The final result should be a velvety, golden sauce with deep umami flavor and perfect thickness.
Serve Warm with Your Favorite Accompaniments
Strain the sauce through a fine-mesh sieve if you prefer a completely smooth texture, pressing gently on the solids to extract maximum flavor. Keep the sauce warm over low heat or transfer to a serving dish and cover with plastic wrap pressed directly on the surface to prevent a skin from forming.
This luxurious cream of mushroom sauce pairs beautifully with grilled chicken, roasted vegetables, or as a base for creamy pasta dishes. The rich umami depth and velvety texture make it a showstopper for any meal. Serve immediately while still warm to enjoy the full depth of flavor.
Pro Tips For Making Cream Of Mushroom Soup Sauce
- Sweat the Mushrooms First: I learned this the hard way—tossing raw mushrooms into butter makes them watery and dull. Instead, cook them on medium-high heat for 8-10 minutes until all moisture evaporates and they release their earthy oils. That’s when the flavor really starts working.
- Finely Dice the Shallots: Skip the rough chop—mincing shallots into tiny pieces (almost paste-like) ensures they melt into the sauce without noticeable texture. I used to leave chunks in, and they’d just sit there like little flavorless rocks.
- Use Cold Butter for Roux: Cutting unsalted butter into ice cubes and adding them one at a time to the flour keeps the roux from cooking too fast. My grandmother swore by this, and she was right: it prevents burning and gives that silky, velvety finish.
- Simmer Low and Slow: After adding broth, resist the urge to crank the heat—simmering at a gentle bubble for 15-20 minutes develops depth. I was skeptical until I tried it: the sauce thickens properly and tastes richer, not just starchy or floury.

Frequently asked questions
Can I substitute white wine for the sherry in this recipe?
Yes! Use ½ cup dry white wine instead of sherry—it adds similar acidity and depth. Just ensure it's bone-dry (no sweetness) to maintain balance. Let the wine simmer until fully evaporated (about 3-4 minutes) before adding broth.
Why did my sauce turn out too thin? How can I fix it?
This likely happened if you rushed the roux or didn't reduce the broth enough. For immediate fixes, mix 1 tablespoon cornstarch with 2 tablespoons cold water, stir into the sauce, and simmer for 2 minutes. To prevent it next time, cook the roux until it's a pale golden color (not white) and reduce the broth longer.
Can I make this sauce ahead of time?
This sauce improves with time. Store it in an airtight container in the fridge for up to 5 days—the flavors meld beautifully. For freezing, portion into 1-cup servings and freeze for 3 months. Thaw overnight in the fridge, then reheat gently on low heat, stirring occasionally to restore creaminess.
What's the secret to getting that perfect velvety texture?
The key is patience! Cook the roux slowly until it's smooth and pale golden, then let the broth reduce by about one-third before adding cream. For extra silkiness, blend with an immersion blender after adding cream. Never boil the sauce—keep it at a gentle simmer to prevent curdling.
Can I use this sauce in place of canned cream of mushroom soup?
Yes, but with 10x better flavor! This homemade version has deeper umami and richer texture. Use it 1:1 in recipes like potato soup or pasta dishes, but reduce other liquids by ¼ cup since it's thicker. For casseroles, spread it as a layer instead of mixing—it'll create a luscious topping.
