Ingredients

  • 4 tablespoons extra virgin olive oil, divided
  • 1/2 small onion, cut into 1/4-inch dice ( 1/2 cup)
  • 4 cloves garlic, minced
  • 8 ounces mushrooms, coarsely chopped
  • 1 small zucchini (about 6 ounces), unpeeled and shredded (1 cup)
  • 1 medium carrot, peeled and shredded ( 1/2 cup)
  • Kosher salt and freshly ground black pepper
  • 1 pound lean ground turkey
  • 2 teaspoons chopped fresh thyme
  • 1 26-ounce jar pasta sauce
  • 3 tablespoons all-purpose flour
  • 2 1/2 cups 1% low-fat milk
  • 1/4 teaspoon ground nutmeg
  • 1 9-ounce box dried no-boil lasagna noodles (16 sheets)
  • 1/2 cup grated Parmesan cheese
  • 1 cup shredded part-skim mozzarella cheese

Method

  • Preheat the oven to 375F.
  • Heat 1 tablespoon of the oil in a large Dutch oven or saucepan over medium heat.
  • Add the onion and cook, stirring frequently, until softened, about 7 minutes.
  • Add the garlic and cook an additional 1 minute.
  • Raise the heat to medium-high, stir in the mushrooms, zucchini, carrot, and salt and pepper to taste and cook, stirring frequently, until the vegetables are softened, about 8 minutes.
  • Add the turkey and thyme and cook until no longer pink, about 5 minutes.
  • Stir in the pasta sauce, heat through, and set aside.
  • Heat the remaining oil in a medium saucepan over medium heat.
  • Add the flour and whisk until smooth, about 2 minutes.
  • Whisk the milk and nutmeg slowly into the flour mixture.
  • Raise the heat and bring to a low boil, stirring constantly.
  • Reduce heat, simmer, and stir until the mixture thickens, about 3 minutes.
  • To assemble, lightly oil or coat a 9 x 13-inch baking pan or dish with nonstick cooking spray.
  • Spread 1 cup meat mixture on the bottom.
  • Lay 5 noodles on top, allowing them to overlap.
  • Break the fifth noodle into a few pieces and fill in empty spaces.
  • Top with 3/4 cup bechamel sauce, 1/4 cup Parmesan, 2 cups meat mixture, and 1/4 cup mozzarella.
  • Repeat with a second layer of 6 noodles (overlapping and two broken), 3/4 cup sauce, 1/4 cup Parmesan, the remaining meat, and 1/4 cup mozzarella.
  • Top with the remaining noodles, bechamel sauce, and cheese.
  • Cover loosely with foil and bake until bubbly, about 50 minutes.
  • Remove the foil and bake until the cheese melts, 5 minutes.
