HOW TO COOK PORTOBELLO MUSHROOM CAP RECIPES

Steps:

• Clean the mushroom caps by wiping away any dirt and cutting off any remaining stems with a paring knife. Remove the gills by scraping them off with a small, round spoon. Place in a single layer on a sheet tray.
• Whisk together the olive oil, soy sauce, balsamic vinegar, garlic, and black pepper in a small bowl. Brush the mixture all over the tops and undersides of the mushroom caps and let them marinate for 15 minutes.
• Preheat a grill or grill pan over medium heat. Place the mushrooms cap-side down and brush the gill side with some of the reserved marinade. Cover and cook for 3 to 4 minutes until golden brown grill marks appear. Flip and baste the tops with more marinade. Cover and cook another 3 to 4 minutes until the mushrooms have charred around the edges, softened, and shrunken slightly.  

Steps:

• Preheat the oven to 400 degrees F.
• Peel the brown skin from the tops of the mushrooms to reveal the cream colored under skin. Toss the mushroom caps with the 2 tablespoons of the olive oil and season with 1 teaspoon of salt and 1/2 teaspoon of pepper. Place the caps on an aluminum foil lined baking sheet, stem-end up, and roast in the oven until well roasted and browned, about 35 to 40 minutes. Remove from the oven and cool for 10 minutes.
• Set a 1-quart saucepan over medium heat and add the butter to the pan. Once the butter is melted, about 1 minute, add the onions and saute until translucent, about 3 minutes. Sprinkle the flour into the pan and stir to form a roux. Continue to cook the roux for 2 to 3 minutes before adding the milk. Bring the milk to a boil and reduce to a simmer, season with the remaining 1/4 teaspoon of salt, 1/4 teaspoon of white pepper and the nutmeg.
• Cook the bechamel sauce for 5 minutes before removing from the heat. Allow the mixture to cool slightly before folding in the crabmeat and cheese. Combine the bread crumbs with the remaining tablespoon of olive oil.
• Spoon 1/3 cup of the bechamel over each mushroom cap and sprinkle 1 teaspoon of the bread crumb mixture over each stuffed mushroom. Place in the oven and roast until the bechamel is bubbling and lightly browned on the edges, about 8 to 10 minutes. Serve immediately.
