Looking for a sauce that can turn any dish around? A creamy mushroom sauce is your best bet. Start with fresh mushrooms sautéed until golden brown, followed by milk or cream to make the sauce of your culinary dreams. And once you make it fresh at home, there’s no way you’d go for a canned soup or a pre-mix. 

Making it from scratch gives you more control over the flavour and texture. The best part is that this simple yet versatile recipe takes only 20 minutes from pan to plate!

What Makes a Mushroom Sauce “Creamy”?

A creamy mushroom sauce doesn't need a long list of ingredients. All it needs is fresh mushrooms and a trip to your pantry. We use mushrooms, aromatics and butter or oil to create the flavour base, while milk or cream gives the sauce its rich, silky texture.

Unlike canned cream of mushroom soup, a homemade sauce lets the mushrooms take centre stage. You can make it lighter or richer, depending on what you're craving. The best part? Fresh mushrooms make all the difference.

How to Make the Creamy Mushroom Sauce, Step by Step

Step 1: Prep the mushrooms

Clean your fresh mushrooms gently by brushing away dirt and wiping them with a damp cloth. Slice larger mushrooms evenly, so they cook at the same rate.

Our go-to tip? Do not slice them too thin. Mushrooms shrink in the pan once they lose moisture, and you want them to retain some texture.

Step 2: Brown them properly

Heat butter or oil in a wide pan and add the mushrooms in a single layer. If the pan is too full, the mushrooms will steam instead of brown. Remember not to add salt at this stage either.

Let them cook until they release their moisture and begin turning golden, stirring occasionally. Once deeply browned, add your onion or shallot and cook until softened.

Ever heard of the Maillard reaction? It’s a chemical process between amino acids and reducing sugars that gives browned food its unique flavour, aroma, and colour. And guess what? It is the most important step for building flavour.

Step 3: Build the creamy base

Add minced garlic and cook for another minute until fragrant. Deglaze the pan with a splash of stock or water - make sure you get all those crispy browned bits from the bottom. Lower the heat and add your milk or cream, stirring to bring everything together.

If you're using flour, sprinkle it over the mushrooms and aromatics before adding the liquid. If using cornflour, mix it with a little cold water first and add it towards the end.

Step 4: Combine and simmer

Let the sauce simmer gently for a few minutes. Avoid boiling it too much, especially if you're using dairy. A gentle heat will help the sauce thicken smoothly. At this point, feel free to add your herbs, black pepper and Parmesan.

Step 5: Adjust the thickness and seasoning

What’s the texture you’re looking for? The sauce should coat the back of a spoon without feeling too heavy. If it's too thick, add a splash of milk or stock. If it's too thin, simmer for a little longer. Be sure to taste your sauce at this point and adjust the salt, pepper and herbs before serving.

Step 6: Serve, or store for later

Use your sauce straight away over pasta, rice, toast, vegetables or potatoes. You can also store it for another meal.

Getting More Mushroom Flavour Into the Sauce

If you want a deeply umami sauce, start with more mushrooms and less liquid. The mushrooms should be the star of the dish, with the cream playing a supporting role.

An underrated tip? Do not rush the browning stage. That golden colour is what we’re after. It means the savoury, caramelised flavours that give the sauce its depth.

The mushroom variety matters too. Shiitake brings a rich, earthy umami flavour, while king trumpet has a substantial texture and savoury character. Oyster mushrooms are milder and more delicate, making them ideal when you want a lighter mushroom dish.

You can also mix and match varieties for a more complex sauce!

How Thick Should It Be?

The ideal consistency depends on how you're planning to use it. Keep in mind that sauces continue to thicken as they cool.

Can You Use Other Fresh Mushroom Varieties?

We wholeheartedly encourage you to unleash your inner culinary scientist! The joy of making a creamy mushroom sauce from scratch lies in experimenting with different varieties.

Try oyster mushrooms for a delicate, tender texture, shiitake for deeper umami, or king trumpet for a meatier bite. Button mushrooms work beautifully too, particularly when you're looking for an everyday sauce.

Storing Leftover Creamy Mushroom Sauce

Allow the sauce to cool before transferring it to an airtight container and refrigerating. It is best used within 3-4 days. When reheating, warm it gently over low to medium heat. Add a splash of milk or stock if it has thickened in the fridge, and stir until smooth.

Add a splash of milk or stock if it is too thick. Cream-based sauces can change texture when frozen and thawed, so refrigeration is a better option. Since this sauce takes only 20 minutes to make, we recommend you enjoy it fresh.

Frequently Asked Questions
