Directions

  1. Duxelles: Place about 2 cups mushrooms in a food processor, and pulse 12 times or until finely chopped, scraping sides of bowl occasionally. Place chopped mushrooms in a large bowl. Repeat procedure in batches with the remaining mushrooms.
  2. Heat a large nonstick skillet over medium-high heat. Add oil to pan; swirl to coat. Add onion, leek, and garlic to pan; sauté 3 minutes or until tender. Stir in mushrooms; sauté 30 minutes or until liquid evaporates, stirring occasionally. Remove from heat; stir in parsley, chives, salt, and pepper. Cool completely. (can be made in advance and freeze in 4 - 1 cup freezer bags). This recipe will use only 1 cup of the mushroom mixture. If used frozen, retain some of the mushroom liquid and add it to the milk mixture (optional).
  3. Potato Gratin: Preheat oven to 375°.
  4. Combine first 6 ingredients in a large stockpot over medium heat; bring to a boil. Reduce heat, and simmer 10 minutes, stirring frequently. Drain potatoes through a sieve over a bowl; reserve potatoes and liquid.
  5. Arrange half of potatoes in an 11 x 7-inch glass or ceramic baking dish coated with cooking spray. Spread Duxelles evenly over potatoes; sprinkle with 1/2 the cheese. Top with remaining potatoes. Pour the reserved cooking liquid over potatoes; sprinkle with remaining 1/2 cheese. Bake at 375° for 50 minutes or until cheese begins to brown. Let stand 5 minutes.
