Where Does This Popular Dish Come From?
Creamy mushroom sauce steak has French roots, of course! It’s a variation of the classic “steak au poivre,” where a rich, creamy mushroom sauce enhances a quality cut of beef. Over time, chefs added their own twists—and here’s mine.
The Star Ingredient: Beef Tenderloin
For this dish, beef quality is key. I recommend 3A Angus tenderloin. Why 3A? It’s all about marbling—those fine streaks of fat within the muscle. The more marbling, the more tender and flavorful the meat. Aim for 150–200g per person—perfect. Tenderloin is a premium, lean cut that melts in your mouth. It’s what gives this dish its luxurious feel.

Mushrooms: Earthy Goodness
I use brown cremini mushrooms. They have a deeper, nuttier flavor than white mushrooms and are widely available.
When choosing mushrooms, check that the insides are white with no suspicious spots. The smell should be earthy and pleasant, never sour.
A Quebec Twist: Fiddleheads
Fiddleheads are a springtime specialty in Quebec. Their flavor is a cross between asparagus and green beans. Before eating, you must boil them to remove natural toxins. I boil them in salted water for 3 minutes. They add a fresh, original touch to the dish.
Important: Always boil fiddleheads for 3 minutes to make them safe to eat.
The Perfect Side: Homemade Fries
Nothing beats homemade fries with this dish! Check out my dedicated fry video. I cut them thick so they’re crispy on the outside, soft on the inside.

Preparation:
In the kitchen, “mise en place” is essential. That means prepping all your ingredients before you start cooking. Clean and slice the mushrooms, bring the beef to room temperature, and lay out your tools and ingredients. This prevents stress and mistakes while cooking.
Cut the mushrooms into even slices. Trim off any damaged parts. This step takes around 15 minutes.

Preparing the Tenderloin:
Pat the beef dry with paper towels. Season generously with salt. Heat a pan over high heat —it needs to be very hot to sear the meat and create a crust. Melt the duck fat in the pan (or place oil in the pan).
The Sear:
Sear the beef on high heat (about 200°C) for 2–3 minutes per side. This gives an even cook and a crispy crust. If you like rare steak, now is the time to remove it from the pan. Otherwise, cook a bit longer.
Set the steak aside.
Butter:
In the same pan, add a generous knob of butter. Butter melts around 30–35°C. Don’t let it burn—it will taste bitter.
Sautéing the Mushrooms: Flavor Fusion
Sauté the mushrooms in the flavorful butter. They’ll soak up the meat juices and develop a golden color. Stir regularly to ensure even cooking.
They should be golden, not burned. Mushrooms should reduce in volume and become tender.

Deglazing with Red Wine: The Sauce Base
Deglaze the pan with a splash of red wine. Pour it into the hot pan and scrape up the caramelized bits with a spatula. Let it reduce by half to concentrate the flavors. A robust red wine works wonders here.
Reducing the wine eliminates acidity and intensifies the flavors.

Richness from Brown Stock: Depth and Umami
Add brown stock (beef stock concentrate) to the sauce. Let it reduce to a thick, velvety consistency like a demi-glace.
Demi-glace is a glossy, rich sauce that coats the meat beautifully.

Finishing the Sauce: Perfect Balance
Stir in a splash of 15% cream for richness and smoothness. Gently mix with a heat-proof spatula. Taste and adjust the seasoning if needed.
The sauce should be thick, silky, and flavorful. Add a pinch of salt or pepper if necessary.

Resting the Steak:
Turn off the heat and return the steaks to the sauce just to rewarm them. Make sure the sauce is hot but not boiling—you don’t want to overcook them.
Sautéing the Fiddleheads: Final Touch
Quickly sauté the fiddleheads in butter. They should stay bright green and a bit crunchy. Add panko breadcrumbs for a crispy texture (optional).
Fiddleheads are delicate—don’t overcook them. They should remain vibrant and slightly crunchy.

Plating: A Mouthwatering Presentation
Slice the tenderloin and lay it on a warm plate. Generously spoon the mushroom sauce on top. Add the sautéed fiddleheads around the steak. Garnish with fresh parsley if desired.
Internal Temperature Check: Precision is Key
Use a kitchen thermometer to check your steak’s doneness. For rare steak, aim for 55°C.
And there you have it! Your creamy mushroom sauce steak is ready to enjoy. I hope you love it as much as I do. Drop me a comment to let me know how it turned out!
