Ingredients and Preparation

Here’s what you’ll need for the recipe:

Ingredients (Serves 4)

• ½ small yellow onion, diced
• 1 tablespoon salted butter
• 12 ounces mushrooms, brown or white, sliced
• Salt and pepper, to taste
• 2 cloves garlic, minced
• 3 sprigs fresh thyme (or ¼ teaspoon dried thyme)
• ½ cup white wine (optional; substitute with chicken broth for a non-alcoholic version)
• ½ cup chicken broth
• ⅔ cup heavy whipping cream
• 1 tablespoon cornstarch
• 3 tablespoons chopped fresh parsley

Ingredient Substitutions

1. Mushrooms: Use a mix of wild mushrooms like cremini, shiitake, or portobello for a richer flavor.
2. Butter: Substitute with olive oil or vegan butter for a dairy-free option.
3. White Wine: If you prefer to skip alcohol, replace it with an equal amount of chicken or vegetable broth for similar depth.
4. Chicken Broth: Swap with beef broth or vegetable broth depending on your preference.
5. Heavy Cream: For a lighter version, use half-and-half or evaporated milk.
6. Thyme: Rosemary or oregano can work as alternatives if thyme isn’t available.

Step-by-Step Instructions

Step 1: Prepare the Ingredients

Before you start cooking, gather all your ingredients and prepare them. Dice the onion finely for an even sauté. Slice the mushrooms thinly—this helps them cook quickly and release their juices. Mince the garlic and chop the parsley, keeping them ready to add later.

Step 2: Sauté the Onion

In a large skillet, melt the butter over medium heat. Once it’s bubbling, add the diced onion. Cook for about 3–5 minutes, stirring occasionally, until the onion becomes translucent and soft. This step builds the base flavor for the sauce.

Step 3: Cook the Mushrooms

Add the sliced mushrooms to the skillet. Sprinkle with a pinch of salt and pepper to help draw out their moisture. Cook for about 5–7 minutes, stirring occasionally, until the mushrooms release their juices and start to brown.

Step 4: Add Garlic and Thyme

Toss in the minced garlic and thyme. Stir well and cook for about 1 minute, or until the garlic becomes fragrant. Be careful not to burn the garlic—it can turn bitter quickly.

Step 5: Deglaze with White Wine

Pour the white wine into the skillet, using a wooden spoon to scrape up any browned bits stuck to the bottom of the pan. This process, known as deglazing, adds depth and richness to the sauce. Let the wine simmer for 2–3 minutes until it’s almost evaporated.

Step 6: Add Broth and Cream

Stir in the chicken broth and heavy whipping cream. Reduce the heat to medium-low and let the mixture simmer gently for about 5 minutes. This allows the flavors to meld together and the sauce to reduce slightly.

Step 7: Thicken the Sauce

In a small bowl, mix the cornstarch with 2 tablespoons of water or broth until smooth. Gradually add the cornstarch slurry to the sauce, a little at a time, stirring constantly. You may not need all of it—stop once the sauce reaches your desired thickness. Let it simmer for 1 more minute.

Step 8: Finish with Parsley

Turn off the heat and stir in the chopped parsley. Taste the sauce and adjust the seasoning with additional salt and pepper if needed.

Beginner Tips and Notes

1. How to Tell If Mushrooms Are Cooked: Mushrooms are ready when they’re golden brown and have released most of their moisture. Avoid overcrowding the pan, as this can cause steaming instead of browning.
2. Avoid Over-Thickening: Add the cornstarch mixture gradually. If you add too much at once, the sauce can become overly thick and gluey.
3. Fixing Overcooked Vegetables: If the mushrooms or onions become too soft, balance the texture by adding some sautéed mushrooms on top when serving.
4. Make-Ahead Tip: Prepare the sauce up to Step 6 and refrigerate it for up to two days. Reheat gently on the stove, adding a splash of broth or cream to refresh the consistency.

Serving Suggestions

This creamy mushroom sauce pairs beautifully with various dishes. Here are some serving ideas:

• Over Protein: Pour it over grilled chicken breasts, steak, or roasted beef for a luxurious finish.
• With Pasta: Toss it with cooked fettuccine or penne for an instant creamy mushroom pasta.
• As a Side: Serve it alongside mashed potatoes or steamed rice for a comforting, hearty meal.
• With Vegetables: Drizzle over roasted vegetables like asparagus, green beans, or carrots.

Leftovers and Storage

• Refrigeration: Store leftover sauce in an airtight container in the fridge for up to three days.
• Reheating: Warm it gently on the stove over low heat. If the sauce thickens too much, add a splash of broth or cream to loosen it.
• Freezing: While it’s possible to freeze the sauce, note that the texture may change slightly due to the cream. Freeze in small portions and thaw overnight in the fridge before reheating.
