Portobello Steaks Au Poivre Ingredients
For the Steaks
• Portobello Mushrooms – Large portobellos (4 to 5 ounces each) are recommended for best results and maximum flavor.
• Unsalted Butter – Adds richness and moisture to the dish; use vegan butter for a dairy-free option.
• Shallot – Adds a subtle sweetness; if unavailable, a small onion can be used as a substitute.
• Garlic – Enhances the aroma and flavor; prep using 4 peeled cloves, smashed for extra impact.
• Whole Peppercorn Blend – Provides the signature peppery coating; if a blend is not available, regular black peppercorns work just fine.
• Vegetable Oil – Used for frying the mushrooms; opt for a neutral oil like canola or sunflower.
For the Sauce
• Fresh Thyme – Adds an herbal freshness; for a different flavor, switch to 1 teaspoon of dried thyme.
• Cognac – Crucial for deglazing the pan and enhancing the sauce depth; you can substitute with brandy or white wine.
• Low-Sodium Vegetable Broth – Adds flavor without excessive salt; homemade broth is ideal for richer flavor.
• Heavy Cream – Creates a luscious sauce; for a dairy-free version, use coconut cream instead.

How to Make Portobello Steaks Au Poivre
-
Prep the Mushrooms: Gently scrape the stems and gills from the portobello mushrooms and discard them. This ensures a wonderfully tender steak texture.
-
Mince and Smash: Mince the shallot and smash the garlic cloves. The smashing releases more flavor, making your dish extra aromatic!
-
Create the Spice Paste: Prepare the spice paste by crushing the peppercorns and combining them with garlic powder, onion powder, and vegetable oil. This fragrant mix will add that signature kick.
-
Heat the Skillet: Heat 2 tablespoons of oil in a skillet over medium-high heat until hot. You want it shimmering but not smoking—perfect for searing those mushrooms.
-
Rub and Sear: Rub the spice paste on the gill side of the mushrooms and place them gill-side up in the skillet. Cook until golden-brown, about 4-5 minutes, then flip and cook for an additional 2 minutes.
-
Baste for Flavor: Reduce the heat to medium-low, and baste the mushrooms with butter, garlic, and thyme for about 2 minutes until tender. This step adds richness and depth.
-
Remove and Keep Warm: Remove the mushrooms from the skillet and keep warm under foil. This helps retain their moisture while you prepare the sauce.
-
Sauté the Shallots: In the same skillet, sauté the shallots in the remaining butter until translucent. They’ll absorb all those flavorful bits left behind.
-
Deglaze the Pan: Deglaze the pan with Cognac, scraping up the brown bits. Add the vegetable broth and let it simmer for 3 minutes to build a robust sauce.
-
Finish the Sauce: Stir in the heavy cream, season with salt, and cook until thickened, about 4-8 minutes. You’ll want a luscious, velvety sauce to coat those mushrooms.
-
Serve and Delight: Slice the mushrooms, serve them topped with the rich sauce, and enjoy every savory bite!
Optional: Garnish with fresh thyme for an extra pop of color and flavor.
