Portobello-Layered Mashed Potatoes Recipe

From The Complete Cooking Light Cookbook by Cathy A. Wexler (Oxmoor House), for About.com

Portobello mushrooms cooked in garlic and onions give a rich touch to this casserole with gold potatoes. The mashed potatoes are made with low-fat buttermilk, then layered with the sauteed mushrooms and topped with Parmesan.

Prep Time: 20 minutes

Cook Time: 55 minutes

Ingredients:

  • 3 pounds Yukon gold potatoes
  • 3/4 cup low-fat buttermilk
  • 1 teaspoon salt, divided
  • 1/4 teaspoon ground nutmeg
  • 1/4 teaspoon black pepper, divided
  • 1-1/2 Tablespoons butter or stick margarine
  • 1/4 cup minced fresh onion
  • 2 garlic cloves, minced
  • 3-1/2 cups finely chopped portobello mushroom caps (about 1 pound)
  • 1/3 cup chopped fresh or 2 tablespoons dried basil
  • Cooking spray
  • 1/4 cup (1 ounce) grated fresh Parmesan cheese
  • 1/2 teaspoon paprika
  • 1/2 teaspoon olive oil

Preparation:

Place gold potatoes in a saucepan, and cover with water; bring to a boil. Reduce heat, and simmer 30 minutes or until tender; drain, reserving 1/2 cup cooking liquid.

Cool and peel potatoes; mash.

Add reserved cooking liquid, buttermilk, 3/4 teaspoon salt, nutmeg, and 1/8 teaspoon pepper, and beat at medium speed of a mixer until smooth.

Melt butter in a medium nonstick skillet over medium-high heat. Add onion and garlic, and saute 2 minutes. Add mushrooms and cook 2 minutes, without stirring. Cook until liquid almost evaporates (about 4 minutes), stirring frequently. Remove from heat, and stir in 1/4 teaspoon salt, 1/8 teaspoon pepper, and basil.

Preheat oven to 375 degrees F.

Spread one-third of potato mixture in bottom of an 8-inch square baking dish or 2-quart casserole dish coated with cooking spray. Spread half of the mushroom mixture over potato mixture; repeat layers, ending with potato mixture. Sprinkle top with Parmesan cheese and paprika. Drizzle with oil.

Bake at 375 degrees F for 25 minutes.
