Creamy Mushroom Sauce

This luscious creamy mushroom sauce is the versatile finishing touch your weeknight dinners long for. Earthy mushrooms become golden and nutty in the pan, then melt into a silky sauce that clings to steak or pasta. The hit of dijon and a whisper of garlic set it apart from the usual, making even the simplest meal feel like a treat.

I whipped up this creamy mushroom sauce for a Sunday steak night last winter and it completely wowed my family. Now I keep mushrooms in the fridge at all times just in case someone drops by hungry.

Ingredients

• Brown mushrooms: These bring rich umami flavor and caramelize beautifully Look for firm mushrooms with no dark spots
• Heavy cream: Delivers silky texture and richness Choose one labeled thickened cream if possible
• Stock: Adds depth and can match your main dish Beef chicken or veg all work Pick low sodium to have more control over salt
• Brown onion: Gives gentle sweetness Thin slices melt into the sauce without overpowering
• Garlic: Fresh minced garlic adds fragrance and warmth Choose plump cloves free of green shoots
• Dijon mustard: Gives that unique gentle tang Opt for smooth dijon for perfect blending
• Cornstarch: Ensures the sauce is perfectly thick Choose a fresh box to avoid lumps
• Unsalted butter: Adds richness and helps everything brown Use good quality for a clean finish
• Salt and pepper: Simple must haves to wake up every ingredient Use a flaky salt and fresh cracked pepper

Instructions

Sauté the Onion:

In a large pan add the butter over medium heat and cook the thinly sliced onions Stir for four to five minutes until the onion softens and becomes almost translucent This sets a sweet base for the sauce

Caramelize the Mushrooms:

Add all the sliced brown mushrooms to the pan and let them cook without moving for a few minutes Once they start to brown stir occasionally and continue cooking until the mushrooms shrink and turn a deep golden color You will want to season them lightly as they cook

Bloom the Aromatics:

Add the minced garlic and stir for a minute until it smells deeply fragrant Be careful not to let the garlic brown or it can taste bitter

Deglaze the Pan:

Pour in the stock and use your spoon to scrape up every bit stuck to the bottom Let the liquid bubble away and reduce by half This concentrates all the flavors

Create the Creamy Base:

Add the heavy cream and the dijon mustard to the pan Stir everything together and bring to a simmer Taste and season as needed Let the sauce gently bubble so the flavors marry

Thicken the Sauce:

Mix the cornstarch with a little cold water in a small bowl until fully dissolved Slowly pour this into the mushroom pan while stirring Simmer for another minute or two until the sauce coats the back of a spoon

Serve:

Pour the sauce over steak pasta or your favorite roasted vegetables Finish with chopped parsley or fresh thyme for brightness

My favorite part of this recipe is those golden bits stuck to the pan after caramelizing the mushrooms scraping them up with the stock is what takes the sauce from simple to truly memorable. Last Thanksgiving my little sister swiped extra sauce for her mashed potatoes and declared it the best part of the whole meal.
