My Famous & Most Popular Creamy Garlic Mushroom Sauce That’s Insanely Good!
This creamy garlic mushroom sauce is a versatile, restaurant-style condiment that elevates simple weeknight dinners and special-occasion meals alike. Built on a base of clarified butter and a touch of olive oil, the sauce combines sautéed garlic, shallot and brown mushrooms with a splash of white wine and fresh herbs before finishing with thickened cream. The result is a silky, flavor-rich sauce that pairs beautifully with steak, chicken, pork, roasted vegetables, mashed potatoes and pies.
The technique is straightforward but focused: high heat to develop color on the mushrooms, careful deglazing to capture concentrated flavor, and gentle simmering to reduce the cream until it coats the back of a spoon. This recipe produces a sauce with a luxurious mouthfeel and deep garlic and mushroom character without overpowering the main protein. It stores well in the refrigerator for several days and reheats gently to preserve texture and emulsion.

Pin Recipe
Ingredients
- 2 Tbsp (28g) – Clarified Unsalted Butter
- 1 tsp (5ml) – Olive Oil
- 1 – Shallot, Finely Diced (Brunoise)
- 4 – Garlic Cloves, Thinly Sliced or Minced
- 300g (10.5oz) – Swiss Brown Mushrooms, Thinly Sliced
- 2 Tbsp (40ml) – White Wine (Substitute For Chicken or Vegetable Stock)
- 5g (0.2oz) – Flat Leaf Parsley, Roughly Chopped
- 2g (0.1oz) – Thyme, Finely Chopped
- 400ml (1 ⅗ Cups) – Thickened Cream
Instructions
-
Heat a large pan over high heat until hot. Add the clarified butter and olive oil and allow them to melt and shimmer.
-
Add the garlic and shallot, stir briefly to combine and sauté for about 30 seconds until fragrant. Add the sliced mushrooms, toss to coat, and continue to sauté over high heat for 6–7 minutes, stirring frequently so the mushrooms brown evenly. Season with salt and pepper halfway through cooking.
-
Pour in the white wine (or stock) and deglaze the pan, scraping up any browned bits. Let the liquid reduce for about a minute. Stir in the chopped parsley and thyme to release their aroma.
-
Stir in the thickened cream and bring the mixture to a gentle boil. Reduce the heat to medium-low and simmer for about 15 minutes, stirring occasionally, until the sauce has reduced and thickened to your desired consistency. Taste and adjust seasoning, then serve warm over your chosen dish.

Recipe Notes
Creamy Garlic Mushroom Sauce Storage Instructions
This sauce keeps well refrigerated for up to four days when stored in an airtight container. Because it is cream-based and emulsified, freezing is not recommended. Freezing and then reheating often causes separation (splitting), where water separates from fats and the sauce loses its smooth texture.
Creamy Garlic Mushroom Sauce Reheating Instructions
To reheat, warm the sauce gently on the stovetop over medium heat, stirring frequently. Add a splash of cream or stock while reheating to refresh the texture and prevent the sauce from becoming grainy. Avoid reheating in a microwave, as uneven, intense heat increases the risk of separation. Reheat slowly until the sauce is warmed through and glossy.
