Yield Makes 10 servings

Number Of Ingredients 11

1 1/2 cups hot water
1 1/2-ounce package dried porcini mushrooms*
1 1/2 pounds portobello mushrooms
12 tablespoons olive oil
4 garlic cloves, minced
4 pounds Yukon Gold potatoes or white-skinned potatoes, peeled, cut into 1/8-inch-thick slices
1/4 cup chopped fresh parsley
1 tablespoon chopped fresh thyme
1 tablespoon chopped fresh rosemary
2 teaspoons salt
1 teaspoon ground black pepper

Steps:

  • Combine 1 1/2 cups hot water and porcini in small bowl. Let stand until mushrooms soften, about 30 minutes. Drain, reserving 2/3 cup soaking liquid. Chop porcini; set aside. Remove and chop stems from portobellos; place in large bowl. Using small spoon, scrape away dark gills from portobellos and discard. Cut portobello caps into 1/2-inch pieces; add to bowl.
  • Heat 3 tablespoons olive oil in heavy large skillet over medium-high heat. Add chopped portobello stems and caps and sauté 4 minutes. Stir in garlic and reserved porcini and sauté until mushrooms are tender, about 10 minutes. Season with salt and pepper. Remove from heat.
  • Preheat oven to 375°F. Coat each of two 13x9x2-inch glass baking dishes with 1 tablespoon oil. Combine remaining 7 tablespoons oil, potatoes, parsley, thyme, rosemary, salt and pepper in large bowl; toss to coat. Layer 1/6 of potato mixture in each prepared dish (there will not be enough to overlap slices). Top potatoes in each with 1/4 of mushroom mixture. Repeat layering. Top with remaining potatoes. Pour 1/3 cup reserved porcini soaking liquid over potatoes in each dish. Cover dishes with foil.
  • Bake gratins 45 minutes. Uncover and bake until tops are brown and potatoes are tender, about 40 minutes longer. (Can be prepared 2 hours ahead. Let stand at room temperature. Cover with foil and rewarm in 350°F oven about 20 minutes.)
  • *Dried porcini mushrooms are available at Italian markets, specialty foods stores and many supermarkets.

PORTOBELLO MUSHROOM GRATIN



Portobello Mushroom Gratin image

I designed this portobello gratin as sort of a mix between my zucchini gratin and my bell pepper gratin with fennel and mushrooms. It's a robust blend of earthy flavors topped with the classic gratin cheese, Gruyere.

Yield 6

Number Of Ingredients 11

4 tablespoons butter
2 leeks, diced
1 celery root, chopped
3 large portobello mushroom caps, diced
1 tablespoon chopped fresh tarragon, divided
1 tablespoon chopped fresh chives, divided
1 cup panko bread crumbs
1 cup grated Gruyere cheese
1 ½ tablespoons all-purpose flour
¾ cup heavy cream
2 tablespoons water, or as needed

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.

  • Assemble the gratin. Layer the cooked mushrooms, sauce, and cheese in a baking dish.
  • Bake the gratin. Bake the gratin until the cheese is melted and bubbly.
