Creamy Portabella Gratin Recipes

PORTOBELLO MUSHROOM GRATIN

Steps:

• Preheat the oven to 400 degrees F (200 degrees C).
• Melt butter in a frying pan over medium heat. Add leeks and celery root and cook for 10 minutes. Add mushroom pieces, 1/2 of the tarragon, and 1/2 of the chives; continue cooking until mushrooms give off liquid, about 6 minutes more.
• Meanwhile, combine bread crumbs and Gruyere cheese in a mixing bowl.
• Add flour to the frying pan with the mushroom mixture. Add cream in a stream and stir until it becomes an even color, about 3 minutes. Add 1/2 of the bread crumb mixture and stir until cheese starts to melt, about 2 minutes. Turn off heat. Transfer mixture to a baking dish and top with remaining tarragon, chives, and bread crumb mixture. Add a small amount of water to moisten the mixture.
• Bake in the preheated oven until the cheese is bubbly, about 10 minutes.
• Use a spatula to scoop portions and serve immediately.

POTATO/PORTOBELLO GRATIN

Steps:

• Heat oven to 400 degrees and butter a 9 by 13-inch baking dish and set aside.
• Using a mandolin, V-slicer or the slicing attachment on a food processor, slice the potatoes approximately 1/8-inch thick. (If you don't want to slice all the potatoes at once, slice them one at a time and build the gratin as you go.) Create the first layer by laying the slices in overlapping rows. Once the first layer is down, season lightly with salt and pepper, then scatter with mushroom slices and a couple tablespoons of the cheese. (Don't over-do it on these layers, if you create a barrier between the adjoining potato layers, the gratin won't set.) Continue building layers until you're out of potatoes or out of room to build, but be sure to save 1/2 cup of the cheese for the top.
• Pour 2/3 cup of the half and half over the gratin then spread both hands over the surface and push down to work the air out from the layers. Add remaining liquid only if half and half does not come to the surface when you push down. Sprinkle the gratin with cheese, cover loosely with foil and place in middle of oven for 1 hour. Check for doneness by inserting the point of a paring knife straight into the gratin. If it goes through smoothly, remove the foil, return to oven, and turn on the broiler just long enough to turn the top golden-brown. Remove, and allow to sit at room temperature for 15 to 20 minutes before serving.

INDIVIDUAL PORTOBELLO MUSHROOM GRATINS

Steps:

• Preheat oven to 350 degrees. Lightly oil a rimmed baking sheet. Arrange portobello caps, gill sides down, on sheet. Bake until tender, 20 to 25 minutes. Transfer to a plate to cool. Preheat broiler.
• Stir together cheese, breadcrumbs, 1 tablespoon parsley, 1 tablespoon chives, and 1 tablespoon oil; set aside.
• Chop portobello stems into 1/2-inch pieces. Heat remaining tablespoon oil in a large skillet over medium heat until hot but not smoking. Add shallots; cook, stirring, until softened, about 2 minutes. Add sliced mushrooms and chopped stems; cook, stirring occasionally, until tender, 6 to 7 minutes. Add wine; cook until most of the liquid has evaporated, about 2 minutes. Stir in cream, remaining 2 tablespoons each parsley and chives, and the salt and pepper. Remove from heat.
• Arrange portobello caps, gill sides up, on a clean baking sheet. Divide mushroom mixture and then crumb mixture among caps. Broil until bubbling and golden brown, about 2 minutes.

CREAMY SALSIFY GRATIN

Steps:

• Fill a large bowl with water and add lemon juice or vinegar.
• Peel the salsify and trim the ends.
• Transfer the salsify to the acidulated water as you peel it.
• Slice the salsify 1/4 inch thick (a mandoline or food processor makes this a quick process).
• Return the salsify immediately to the water to keep it white.
• Move the oven rack to the upper third of the oven and preheat oven to 400°F.
• In a large soup pot, melt the butter.
• Add the flour and cook over moderate heat for 2 minutes, whisking constantly.
• Add the half-and-half and bring to a boil, whisking constantly.
• Cook, whisking, for about 3 minutes, or until the half-and-half is slightly thickened.
• Season with salt, pepper and nutmeg.
• Drain the salsify and pat it completely dry.
• Add the salsify to the pot and cook over moderate heat, stirring occasionally to prevent scorching, until tender, 25 to 30 minutes.
• Pour the salsify mixture into a 9 x 13 inch baking dish and sprinkle with the cheeses.
• Bake for 20 minutes, until the cheese is melted and the casserole is bubbling.
• Preheat the broiler and broil the gratin for about 5 minutes, or just until the cheese is golden and crusty.
• Let the gratin stand for 10 minutes before serving.

CREAMY PORTABELLA GRATIN

PORTOBELLO GRATIN

Steps:

• Split 6 portobello mushroom caps to make 12 thin rounds. Toss 1 1/4 cups shredded muenster cheese, 1/3 cup breadcrumbs, 2 tablespoons chopped parsley, 1 grated garlic clove, and salt and pepper. Layer the portobello rounds and cheese mixture in a baking dish, making 3 layers of each. Drizzle with 3 tablespoons water, cover with foil and bake at 400 degrees F, 35 minutes. Uncover and bake 8 more minutes.

FARRO AND MUSHROOM GRATIN

Steps:

• Heat oven to 425 degrees. Bring a medium pot of well-salted water to a boil over high heat.
• Add farro to the pot, and cook according to package directions until tender (which should be about 20 to 30 minutes). Drain well in a colander. While still warm (and leaving the farro in the colander, if you like), drizzle the grains with enough olive oil to coat lightly, tossing well to prevent from sticking. Set aside.
• While farro is cooking, prepare the mushrooms: In a large ovenproof skillet, heat 3 tablespoons of the oil over medium-high until hot but not smoking. Add enough of the mushrooms to cover the skillet in one layer without crowding and half the thyme. Cook, undisturbed, until bottoms of the mushrooms are golden brown, 3 to 5 minutes. Stir and let brown on the other side, 2 to 3 minutes more. Use a slotted spoon to transfer mushrooms and thyme to a plate, and season with salt and pepper. Add another 2 tablespoons oil to the pan and repeat with another layer of mushrooms and thyme, adding them to the plate when done. Repeat with any more mushrooms if necessary.
• Add remaining 1 tablespoon oil to skillet and stir in shallots and a large pinch of salt and pepper. Sauté until tender and golden brown, 4 to 6 minutes.
• Remove skillet from heat and return mushrooms to the pan (discarding the thyme sprigs). Stir in farro, mascarpone and 3/4 cup parsley. Taste and add more salt and pepper, if needed. Spread mixture evenly in the skillet and sprinkle Gruyère on top. Bake until the farro is hot and Gruyère is melted, 10 to 15 minutes. Turn on broiler and broil for 1 to 2 minutes until Gruyère starts to bubble and develop brown spots.
• Sprinkle with remaining parsley and serve with lemon wedges for squeezing on top, if you'd like.
