This spinach pierogi casserole can be spiced to your liking. Once you've mastered the recipe, try using other savory pierogi in place of the potato and cheese version. —Susan Skrtich, Hamilton, Ontario

Ingredients

  • 1 teaspoon olive oil
  • 1 medium onion, chopped
  • 1 tablespoon minced garlic
  • 1 tablespoon minced fresh basil
  • 1/2 teaspoon salt
  • 1/2 teaspoon pepper
  • 1 cup meatless pasta sauce
  • 1 package (14 ounces) frozen potato and cheese pierogi, thawed
  • 1-1/2 cups frozen chopped spinach, thawed and squeezed dry
  • 1 large egg, lightly beaten
  • 1 cup frozen cubed butternut squash (about 5 ounces)
  • 1-1/2 cups shredded part-skim mozzarella cheese
  • 1/2 cup sour cream, optional

Directions

  1. Preheat oven to 350°. Line a 9x5-in. loaf pan with foil, letting ends extend up sides; grease foil.
  2. In a small skillet, heat oil over medium-high heat. Add onion; cook and stir until tender, 6-8 minutes. Add garlic, basil, salt and pepper; cook 1 minute longer. Remove from the heat.
  3. Spread 1/2 cup pasta sauce into prepared pan. Top with pierogi; press firmly. Top with onion mixture. Mix spinach and egg; spoon over onion mixture. Spread squash evenly over spinach; spoon remaining 1/2 cup pasta sauce over top. Sprinkle with cheese. Bake until bubbly and cheese is golden brown, 55-65 minutes.
  4. Let stand 10 minutes. Lifting with foil, remove from pan. Cut into slices. Serve with sour cream if desired.
