Ingredients

Preparation Time: 10 minutes
Cook Time: 20 minutes
Yield: 6 servings

• 3 tablespoons butter
• 1 tablespoon olive oil
• 1 medium onion, finely chopped
• 4 cloves garlic, minced
• 500g mushrooms (button or cremini), sliced
• 1 teaspoon salt (adjust to taste)
• 1/2 teaspoon black pepper
• 1 teaspoon dried thyme (or 1 tablespoon fresh)
• 1 cup heavy cream
• 1/2 cup chicken or vegetable broth
• 1/2 cup grated Parmesan cheese
• 1 tablespoon all-purpose flour (optional, for thickening)
• Fresh parsley, chopped (for garnish)

Instructions

1. I start by heating the butter and olive oil together in a large skillet over medium heat. This combination gives the sauce a rich flavor while preventing the butter from burning.
2. Next, I add the chopped onions and sauté them for about 3–4 minutes until they become soft and translucent. This step builds the base flavor of the creamy garlic mushroom sauce.
3. I stir in the minced garlic and cook for about 30 seconds until fragrant. Be careful not to burn it, as garlic can turn bitter quickly.
4. Then, I add the sliced mushrooms and cook them for about 8–10 minutes. At first, they release moisture, but I keep cooking until the liquid evaporates and the mushrooms start to brown. This is key for developing that deep, earthy flavor.
5. I season the mixture with salt, black pepper, and thyme, stirring well to evenly distribute the spices.
6. If I want a slightly thicker sauce, I sprinkle in the flour and stir for about a minute to cook out the raw taste.
7. Next, I pour in the broth and let it simmer for 2–3 minutes, allowing the flavors to meld together.
8. I reduce the heat to low and slowly add the heavy cream, stirring continuously to create that smooth, creamy texture.
9. Once the sauce begins to gently simmer, I stir in the Parmesan cheese until it melts completely and the sauce becomes rich and silky.
10. I let the creamy garlic mushroom sauce cook for another 3–5 minutes until it reaches my desired consistency, then taste and adjust seasoning if needed.
11. Finally, I garnish with freshly chopped parsley and serve immediately.

Tips or Variations

One of the reasons I love this creamy garlic mushroom sauce is how flexible it is. You can easily tweak it to suit your taste or what you have available in your kitchen. If you prefer a lighter version, you can substitute half-and-half for the heavy cream, though the sauce will be slightly less rich.

For a deeper flavor, I sometimes add a splash of white wine after cooking the mushrooms and let it reduce before adding the cream. It adds a subtle tang that pairs beautifully with the garlic and mushrooms.

If you’re a fan of bold flavors, try adding a pinch of chili flakes for a gentle heat. You can also mix in spinach or sun-dried tomatoes for extra texture and color. This creamy garlic mushroom sauce works wonderfully with pasta, grilled chicken, steak, or even as a topping for baked potatoes.

For a vegetarian version, simply use vegetable broth instead of chicken broth. You can also experiment with different types of mushrooms like portobello or shiitake for a more complex flavor profile.
