How to Make Healthy Lasagna

  1. Preheat oven to 400°F (200°C).
  2. In a large pot, heat 2 tablespoons olive oil over medium heat. Add 1 medium onion, chopped, and 2 cloves minced garlic. Cook, stirring occasionally, for 5 minutes.
  3. Stir in 28 ounces (794g) canned crushed tomatoes, 1 teaspoon dried oregano, 1/2 teaspoon salt, and 1/2 teaspoon black pepper.
  4. Reduce heat and simmer for 30 minutes, or until thickened. Set aside.
  5. While the sauce simmers, in a 12x15 inch baking pan, toss 1 medium butternut squash (about 1.5 lbs), peeled, seeded, and cubed, with 1 tablespoon olive oil, 1 teaspoon fresh thyme, 1/4 teaspoon salt, and 1/4 teaspoon black pepper. Add 4 whole garlic cloves.
  6. Bake for 10-15 minutes, or until squash is tender. Reduce oven temperature to 350°F (175°C).
  7. Transfer the baked squash to a food processor and puree.
  8. Meanwhile, remove stems from 1 bunch (about 10 oz) kale. Wash and boil the leaves for 5-10 minutes, or until tender. Drain and cool.
  9. Bring 3 quarts of water to a boil in a large pot. Add 9-12 lasagna noodles (oven-ready preferred) and cook according to package directions. Drain and rinse with cold water.
  10. In a bowl, combine 15 ounces (425g) ricotta cheese, 1/4 teaspoon nutmeg, 1 cup shredded mozzarella cheese, 1/4 teaspoon salt, and 1/4 teaspoon black pepper.
  11. In a 9x13 inch baking pan, spread 1/3 of the tomato sauce. Layer 3 noodles, then half of the pureed squash, and half of the kale. Repeat layers: 3 noodles, ricotta mixture, remaining kale, and 3 noodles.
  12. Top with the remaining tomato sauce and remaining mozzarella cheese.
  13. Bake for 30 minutes, or until bubbly and cheese is melted. Let stand for 10 minutes before serving.
  14. For make-ahead: Assemble the lasagna as directed and refrigerate overnight. Add 10-15 minutes to baking time. For frozen lasagna, bake for 1 hour and 15 minutes from frozen.
