Best 11 Roasted Portobello Melts Recipes

PORTOBELLO PATTY MELTS

Steps:

• Caramelize onions. Melt 2 tablespoons of the butter in a large skillet set over high heat. When it foams, add the onions and sprinkle with salt. Do not stir immediately. Wait 1 minute, then begin to stir frequently over high heat for 5 minutes or so, or until the onions have released some liquid and started to become translucent.
• Reduce the heat to medium, and cook, stirring often, for what will seem like a very long time, until the onions are fully melted and dark golden brown, approximately 30 to 40 minutes. Remove onions, and set them and the skillet aside. (You can caramelize the onions a day ahead of time and reheat slowly when you're ready to cook.)
• Take a small baking dish, and put into it olive oil, soy sauce, balsamic vinegar and minced clove of garlic. Add portobello caps, then cover with foil, and roast in a 400-degree oven for 30 to 45 minutes, turning once.
• Set the skillet to medium heat, and put four pieces of rye bread into the butter that remains from cooking the onions. Top each piece with a slice of cheese, then two portobello caps, then some of the caramelized onions, and finally another slice of cheese and another slice of rye. Use the spatula to press down on the packages, and after about a minute or so, carefully turn over each patty to begin to brown the other side. (You may need to add the additional butter.) Cook until the cheese is fully melted and the bread is golden brown and crisp on both sides. Slice in half before serving.

• Preheat the oven to 425 degrees F. Arrange the mushrooms on a baking pan and roast until browned and tender, about 30 minutes. Transfer the mushrooms to a serving plate and drizzle with the liquid from the pan.
