Best Portobello Steaks With Mashed Celery Root Recipes

PORTOBELLO STEAKS

Steps:

• Remove stems and clean the mushrooms; set aside.
• Mix vinegar, Worcestershire, oil, garlic, onion powder, salt, and pepper together in a small bowl.
• Place mushrooms inside a large zip-top bag. Pour in the marinade and turn the bag so the mushrooms get evenly coated. Let sit in a refrigerator for a minimum of 5 minutes, or up to 12 hours.
• Spray a large skillet with cooking spray and heat over high heat. Grill mushrooms in the hot pan until heated through and browned, about 4 minutes per side.

VEGETARIAN CHICKEN-FRIED PORTOBELLO MUSHROOM STEAKS

Steps:

• Position an oven rack at the top of the oven, and preheat the broiler. Arrange the mushrooms on a baking sheet, and broil until the sides facing up begin to soften, about 5 minutes. Flip, and continue to broil until the sides facing up are soft, about 5 minutes more. Let cool.
• Put the mushrooms, gill-side up, between 2 pieces of plastic wrap, and pound to about 1/4 inch thick with a meat mallet. Season all over with 1/2 teaspoon salt.
• Whisk together the flour, baking powder and 1 teaspoon each salt and pepper in a shallow dish. Whisk together the milk and eggs in a separate shallow dish.
• Lower the oven heat to 250 degrees F. Put a rack over a rimmed baking sheet. Heat about an inch of oil to 350 degrees F in a large cast-iron skillet or Dutch oven over medium-high heat.
• While the oil heats, dredge each mushroom in the flour mixture to completely coat; shake off any excess. Then dip into the egg mixture until fully coated; let the excess drip off. Return the mushroom to the flour mixture, and dredge a second time, until completely coated, pressing firmly into the flour mixture. Arrange on one side of the rack on the baking sheet.
• Add 2 of the breaded mushrooms to the hot oil, and cook, turning once, until crisp and golden, about 5 minutes total. Transfer the mushrooms to the unused side of the rack. When the oil comes back to temperature, repeat with the remaining 2 mushrooms and keep the first 2 warm in the oven.
• Serve the mushroom steaks with mashed potatoes and generous spoonfuls of hot gravy. Garnish with chives or scallions if using.
• Position an oven rack in the top position in the oven and preheat to 450 degrees F. Toss the onions, celery, carrots and garlic with the oil and 1 teaspoon salt on a rimmed baking sheet. Roast until the vegetables are charred in some places, 25 to 30 minutes.
• Bring the roasted vegetables, 1 cup water, mushrooms, thyme, sun-dried tomatoes, soy sauce, bay leaf and 1 teaspoon salt to a simmer in a medium saucepan over medium-high heat. Cook, stirring occasionally, until most of the liquid is gone, 8 to 10 minutes. Add 6 cups water and 1/2 teaspoon salt, and bring back to a simmer. Reduce the heat to medium-low, and gently simmer until reduced by about one third, about 45 minutes. Strain the stock into a large liquid measuring cup, then squeeze all the liquid out of the solids with the back of a ladle (there should be about 4 cups of stock); discard the solids. (If not making gravy right away, let the stock cool to room temperature, then refrigerate for up to 3 days or freeze for up to 1 month; warm slightly before making gravy.)
• Melt the butter in a medium saucepan over medium heat. Add the sage leaves to the butter, and stir for 30 seconds; remove the fried sage leaves, and set aside. Add the flour to the saucepan, and stir until smooth and lightly golden, about 2 minutes. Slowly pour in the warm stock while whisking constantly until smooth and thick, 8 to 10 minutes.
• Chop the fried sage, stir it and the parsley into the gravy and season to taste with pepper.

PORTOBELLO 'STEAK' AU POIVRE

Steps:

• Brush the mushrooms all over with olive oil. Sprinkle the pepper evenly over the gill sides (about 1/2 teaspoon per mushroom). Heat a large cast-iron skillet over medium-high, then add the mushrooms gill side up and sear until the underside is browned and the gill side looks wet, 3 to 6 minutes. Flip and cook until golden and the pepper is fragrant, 2 to 4 minutes.
• Reduce heat to medium-low. Flip the mushrooms so they're gill side up, then add the butter and garlic, and season with salt. While stirring the garlic to keep it from scorching, tilt the skillet to spoon up the melting butter and baste the mushrooms until tender, 2 to 5 minutes. Transfer the mushrooms to a plate, leaving the butter in the skillet.
• Add the shallot and stir until softened, 2 to 4 minutes, adding a little more butter if the pan is dry. Stand back, and carefully add the Cognac. (It might flame.) Stir until the Cognac has nearly evaporated. Add the heavy cream and mustard, season with salt, and stir to combine. Return the mushrooms to the pan gill side down, and cook until the cream is thickened and the color of a latte, 2 to 4 minutes. Eat the mushrooms with a drizzle of the sauce.

PORTOBELLO STEAKS WITH MASHED CELERY ROOT

Steps:

• Preheat the oven to 350˚F.
• Overnight, or several hours in advance, make the marinade and set it aside.
• Remove the stems from the mushrooms, then use a fork to remove the gills. Do so by gently scraping in the direction of the gills about 1/8-inch deep. Set the mushrooms top side down in a baking dish and pour the marinade over them. Let them sit for at least 20 minutes or up to 8 hours.
• While the mushrooms marinate, place the whole celery root into a glass baking dish with about 1/4 inch of water in the bottom. Cover the dish with tinfoil and roast the root in the oven for 45 minutes to 1 hour. Remove the tinfoil and allow the root to cool until you can handle it with your hands.
• Use a knife to peel away the celery root skin, then roughly chop the root and place the pieces into a food processor. Purée the root with the horseradish and coconut butter, and add enough almond milk for the mixture to reach a mashed potato-like texture and consistency. Season with sea salt then fold in the chopped scallions. Set aside and keep warm.
• Place the mushrooms onto a baking dish and cook in the oven until tender, about 10 to 12 minutes.
• Slice the mushrooms then set them on top of mounds of the celery root mash. Enjoy with garlicky greens or roasted asparagus.
