Mushroom and Mustard Sauce Recipe

Prep Time 10 minutes

Cook Time 15 minutes

Total Time 25 minutes

Ingredients

2 tablespoons unsalted butter
1 tablespoon olive oil
12-16 oz (350-450g) fresh mushrooms (cremini or mix), cleaned and sliced
1 shallot or ½ small onion, finely chopped
3 cloves garlic, minced
2 tablespoons Dijon mustard
1 tablespoon whole-grain mustard
1 cup heavy cream
½-¾ cup beef, chicken, or vegetable broth (low-sodium)
1 teaspoon fresh thyme leaves (or ½ teaspoon dried)
Salt and freshly ground black pepper, to taste
2 tablespoons fresh parsley, chopped (for garnish)
Optional: splash of white wine or sherry for deglazing

Instructions

Prep ahead for ease — Slice mushrooms evenly, chop shallot, mince garlic, measure mustards and cream, chop parsley. Everything ready means smooth, enjoyable cooking!
Heat your skillet — Set a large pan over medium-high. Add olive oil and 1 tablespoon butter—let it foam and heat up for golden mushroom magic.
Brown the mushrooms — Toss in sliced mushrooms with a pinch of salt/pepper. Spread out and cook 4-6 minutes undisturbed until deeply golden—stir occasionally for even color.
Aromatics bloom — Lower heat to medium, add remaining butter, shallot, and garlic. Stir 1-2 minutes until softened and fragrant—don't let garlic burn!
Deglaze deliciously — Pour in broth (or wine if using), scraping up all browned bits from the pan. Let bubble 1-2 minutes to reduce and intensify flavor.
Mustard magic — Stir in both Dijon and whole-grain mustard until fully mixed—taste and add more if you crave extra tang!
Cream it up — Lower heat, slowly pour in heavy cream while stirring. Bring to a gentle simmer (no hard boil) for 4-6 minutes until sauce thickens nicely.
Herb and season — Add thyme, taste, and adjust with salt/pepper—mustard adds punch, so season carefully. Simmer 1-2 more minutes if needed for clingy texture.
Final polish — If too thick, splash in extra broth; remove from heat for best creaminess. Stir in most parsley for fresh pop.
Plate and wow — Spoon generously over steak, chicken, pork, or pasta. Garnish with extra parsley—sit back and enjoy the compliments on this tangy, creamy masterpiece!

Notes

Adjust mustard to taste—start conservative if new to the combo. Naturally gluten-free (check broth). Excellent with seared meats; for pasta, thin with pasta water. Use fresh mushrooms for texture—canned won't brown well. The mustard brightness cuts richness perfectly for balanced indulgence!

Recipe Tips and Tricks

Brown mushrooms thoroughly on high heat without crowding for deep caramelization—pat dry first for better sear.
Use a mix of Dijon (smooth) and whole-grain mustard for layered flavor and nice texture contrast.
Add mustard off the heat or on low to prevent curdling the cream.
Deglaze well to capture all browned bits for maximum savoriness.
Simmer gently after cream addition—no vigorous boil to keep sauce smooth.
Taste before extra salt—mustard and broth bring plenty of seasoning.
For thicker sauce, reduce longer or whisk in a tiny cornstarch slurry.

Ingredients Notes

Mushrooms — Fresh cremini (baby bella), button, or a mix (12-16 oz/350-450g) for meaty texture and rich umami—slice evenly and clean gently to maximize browning and flavor absorption.
Mustard — Dijon for smooth sharpness and whole-grain for texture and mild heat—use quality brands for best taste; about 2-3 tbsp total.
Heavy cream — Full-fat for luxurious silkiness and stable emulsion; lower-fat may separate.
Broth — Beef for steak pairings, chicken/vegetable for lighter options—low-sodium to control salt.
Aromatics — Shallot/onion and fresh garlic for sweet-savory base that complements mustard.
Butter/oil — Butter for richness, oil to prevent burning during high-heat sauté.
Herbs — Fresh thyme or parsley for brightness—thyme early, parsley at end.

Variations and Substitutions

Grainy focus: Use only whole-grain mustard for rustic texture and bolder bite.
Lighter: Swap half-and-half or evaporated milk; thicken with cornstarch if needed.
No cream: Reduce broth/wine longer with butter for a pan sauce style.
Spicy: Add cracked black pepper, horseradish, or cayenne for extra heat.
Herb twists: Tarragon or rosemary instead of thyme; chives for garnish.
Protein add-ins: Stir in bacon bits or browned sausage for heartier sauce.
Vegan: Use plant-based cream/butter, vegetable broth, and vegan mustard.
Wine enhancement: Deglaze with dry white wine or sherry for complexity.

Storage Options

Refrigerate in an airtight container for up to 4 days. Reheat gently on low stovetop, adding a splash of broth or cream to loosen—stir often to prevent separation. Microwave in short bursts with stirring. Freezes for 1-2 months (thaw in fridge); reheat slowly with extra liquid if sauce separates slightly.
