Few things make steak dinner feel as special as a luscious homemade mushroom sauce. This recipe is simple enough for a weeknight but fancy enough to impress guests at a celebration meal thanks to layers of flavor from butter, good wine, garlic, and the deep earthiness of real mushrooms. Once you master this sauce you will want to put it on steak chicken potatoes or even just a hunk of bread.
I whipped this up on a whim when a friend popped by with a surprise steak and we still talk about that meal. It is comforting but elegant and always makes dinner feel like an event.
Ingredients
- Portobello mushrooms: sliced thick This keeps their texture perfect through browning plus they pack extra umami. Look for firm smooth caps
- Butter: For sautéing and adding richness Use the best quality you have salted or unsalted goes
- Shallots: These build a gentle base flavor Milder than onion and a little sweet Buy plump blemish-free shallots
- Garlic: Fresh always gives the sharpest punch Measure with your heart but fresh is best
- Fresh rosemary: Delivers a fragrant herby note Just a spoonful chopped fine Dried works but use less
- Wine: Port merlot or sherry will all bring depth and just a hint of sweet Try to use something you would enjoy drinking
- Chicken broth: Keeps it savory Go for low-sodium if you like to control salt
- Heavy cream: Makes it silky and spoonable Whole milk or half and half both swap in well but cream gives the richest sauce
- Cornstarch and cold water: This combo helps the sauce thicken Use only if needed begin with the smallest amount to avoid a gummy texture
Step-by-Step Instructions
- Prep the Mushrooms:
- Clean mushrooms well then pat dry Slice into thick pieces About a half-inch thick is perfect This ensures they stay juicy through double cooking
- Sauté the Shallots:
- Melt a generous knob of butter in your largest skillet over medium-low Add finely diced shallots and cook gently for about six minutes until soft and translucent This slow build makes a sweet aromatic foundation
- Brown the Mushrooms in Batches:
- Raise heat to medium high Add a fraction of sliced mushrooms so they sit in a single layer Let them sear untouched for two to three minutes each side Repeat in two more batches always letting the pan come back to heat and adding more butter as needed This browning step unlocks the deep mushroom flavor
- Deglaze with Wine and Herbs:
- Once all mushrooms are browned pull the last batch out Add minced garlic chopped rosemary and pour in the wine Use a wooden spoon to scrape up every brown bit from the pan bottom These sticky leftovers transform into flavor as the wine bubbles and reduces for two minutes
- Simmer with Broth and Cream:
- Return all browned mushrooms plus any juices back to the skillet Pour in chicken broth and heavy cream Season gently Simmer uncovered until the sauce thickens and mushrooms are meltingly tender Taste and adjust salt and pepper
- Adjust Thickness:
- In a small bowl mix a splash of cold water with a teaspoon of cornstarch Stir half of this slurry into the sauce and let it cook for one minute If you want it thicker add the rest If you want it thinner simply stir in a touch more broth
