While this recipe is delicious using ingredients exactly as listed, it’s also a smart way to make the most of any leftover potatoes and veggies. Use 2-1/2 cups leftover mashed potatoes and whatever cooked vegetables you have on hand. You can also substitute 1/2 pound Italian sausage for the bacon if you want a heartier quiche. —Heather King, Frostburg, Maryland

Ingredients

  • 1 package (24 ounces) refrigerated mashed potatoes
  • 2 tablespoons olive oil, divided
  • 8 ounces sliced fresh mushrooms
  • 2 garlic cloves, minced
  • 5 ounces frozen chopped spinach, thawed and squeezed dry (about 1/2 cup)
  • 6 bacon strips, cooked and crumbled or 1/3 cup bacon bits
  • 2 teaspoons minced fresh rosemary or 1/2 teaspoon dried rosemary, crushed
  • 4 large eggs
  • 1 cup 2% milk
  • 1/4 teaspoon pepper
  • 1 cup shredded cheddar cheese

Directions

  1. Preheat oven to 350°. Press mashed potatoes onto bottom and up sides of a greased 9-in. deep-dish pie plate. Brush with 1 tablespoon oil. Bake 30 minutes or until edges are golden brown.
  2. Meanwhile, in a large skillet, heat remaining oil over medium-high heat. Add mushrooms; cook and stir 3-4 minutes or until tender. Add garlic; cook 1 minute longer. Remove from heat. Stir in spinach, bacon and rosemary; spoon over crust. In a small bowl, whisk eggs, milk and pepper until blended; stir in cheese. Pour over mushroom mixture.
  3. Bake 25-30 minutes longer or until golden brown and a knife inserted in the center comes out clean. Let stand 10 minutes before cutting.
