Let’s get started!
Creamy Mushroom Sauce Ingredients
This recipe makes 2 cups of creamy mushroom sauce. If you only need 1 cup of sauce, cut the ingredients in half and it turns out just as well.
Heavy cream: This creamy mushroom sauce is made with heavy cream. I haven’t tested it with half and half. And if you’re wondering if you can make a cream sauce with milk – nope. Milk does not provide the richness and body you want in a cream sauce.
Cremini mushrooms: Use cremini mushrooms (aka Baby Bella) rather than white button mushrooms. Cremini mushrooms are much more flavorful.
Garlic: For the best flavor, mince two cloves of garlic right before you’re ready to start making this cream sauce.
Yellow onion: Slice and chop the onion into 1/2 inch pieces until you have half a cup.
Butter: We’ll use butter to create a roux for thickening the sauce, and to cook the onion.
Flour: I use gluten-free flour to thicken the cream sauce, but if you’re not gluten-free you can use regular flour.
Salt and pepper to taste
How to Make Creamy Mushroom Sauce in 3 Steps!
Step 1: Make a Roux
We’re going to thicken our cream sauce with a roux. A roux is a technique common in French cooking to thicken sauces. But don’t worry, it’s very easy to make one. We’ll create our roux with equal parts fat and flour. In this case, we are using butter as the fat.
How to Make a Roux
- Place a small sauce pan over very low heat on your stovetop. Add 2 tablespoons of butter and let it melt. When it’s melted, add 2 tablespoons of flour and stir quickly to fully combine the flour and butter.
- Remove it from the heat when the ingredients are combined and it starts to smell like pie crust. This will take less than a minute or so.
Step 2: Simmer the Sauce
Melt half a tablespoon of butter in a separate frying pan and add the onion. Stir frequently until the onion is soft.
Add the heavy cream to the onion, plus half a cup of water and the minced garlic. Stir well to combine.
Carefully add sliced mushrooms to the mixture and bring it to a gentle simmer. Avoid boiling the sauce. Boiling increases the risk of a broken sauce.
Stir occasionally until the mushrooms are cooked. This will take about 15 minutes depending on how lively the simmer is.
3. Thicken the Sauce
Next, add half of your roux to the sauce and stir well to combine. The sauce will start to thicken. Give it half a minute, then judge whether you want to add more roux for a thicker sauce, or less for a thinner sauce.
Continue adding roux and stirring the cream sauce until it reaches your desired consistency.
Remove the sauce from heat and stir before serving.
Recipe Tips and Tricks
– Prepare all ingredients before starting
In French cooking, the term mise en place means to “put in place” or gather your ingredients.
Ever watch a cooking show and the host has all the ingredients measured out into little bowls? Yep, that’s what we’re talking about.
Having the ingredients ready to go before you start is especially important when making a cream sauce. The sauce comes together so quickly that there isn’t time to stop and slice the mushrooms or mince the garlic.
Frequently Asked Questions
Why is there a skin forming on top of my cream sauce?
A skin forms on top of a cream sauce because water on the surface of the sauce evaporates more quickly. The skin is harmless though, just stir it back into the sauce.
Can I make creamy mushroom sauce ahead?
Absolutely. Store the sauce in a container with a tight lid in your fridge. Reheat over low heat on the stovetop when you’re ready to use it. Be sure to stir well.
How long will homemade cream sauce last in the fridge?
Let’s be honest, I haven’t done a study to see how long cream sauce keeps in the fridge. But aren’t our human instincts of sight and smell pretty spot on? If it smells bad or looks bad, throw it out.
Can I freeze this mushroom sauce?
I tried freezing this mushroom sauce and it did not work out. After a week in the freezer the sauce took on a gritty texture when I thawed and reheated it.
Can I make a mushroom cream sauce with milk?
I have not made mushroom cream sauce with milk and would not recommend it. Milk has a different flavor profile from cream. So even if you thicken the milk more aggressively, it won’t taste nearly as rich as a cream sauce made with actual cream.
Can I make creamy mushroom sauce with half and half?
I have not tried making this creamy mushroom sauce with half and half so I can’t recommend it. Half and half is made by combining whole milk with cream, so while you could definitely make a cream sauce with half and half, the flavors won’t be as rich.
Can I substitute garlic powder instead of fresh garlic?
I do not recommend this using anything other than freshly minced garlic in this sauce.
