This version, packed with vibrant winter vegetables, offers that same sense of nostalgia, but with a lighter, healthier twist – proving that you can indulge without compromising your well-being.

Recipe Overview

• Prep Time: 45 minutes
• Cook Time: 40 minutes
• Total Time: 1 hour 25 minutes
• Servings: 8
• Yield: 1 Lasagna
• Dietary Type: Healthy, Vegetarian

Ingredients

• 4 tablespoons olive oil, divided
• 1 red onion, peeled and sliced
• 3 garlic cloves, peeled (1 minced, 2 left whole)
• 2 (14 1/2 ounce) cans tomatoes, crushed
• 1 teaspoon oregano, dried
• 1 teaspoon salt
• 1 teaspoon pepper
• 6 cups butternut squash, peeled and cut into cubes
• 1⁄2 teaspoon thyme, dried
• 1 lb kale
• 9 whole wheat lasagna noodles
• 1 (15 ounce) container part-skim ricotta cheese
• 1⁄8 teaspoon nutmeg, ground
• 2 cups mozzarella cheese, divided

Equipment Needed

• Large pot
• 12 x 15 inch baking pan
• Food processor
• 9 x 13 inch baking pan

Instructions

1. Preheat oven to 400°F.

2. In a large pot over medium heat, heat 2 tablespoons of the olive oil. Stir in the red onion and minced garlic (1 clove). Cook, stirring occasionally, for 5 minutes, until the onion is softened.

3. Stir in the crushed tomatoes, oregano, 1/2 teaspoon salt, and 1/2 teaspoon pepper. Reduce heat and simmer for 30 minutes, or until the sauce has thickened. Set aside.

4. While the sauce is simmering, in a 12 x 15 inch baking pan, place the butternut squash cubes. Sprinkle with the thyme, remaining olive oil (2 tablespoons), and remaining salt and pepper (1/2 teaspoon each). Add the whole garlic cloves (2) and toss to combine.

5. Bake for 10-15 minutes, or until the squash is soft. Don’t overcrowd the pan; roast in batches if necessary for even cooking.

6. Reduce oven temperature to 350°F.

7. Transfer the roasted squash mixture to a food processor and puree until smooth. Add a splash of water or vegetable broth if needed to achieve a creamy consistency.

8. Tear kale leaves from the ribs—discard the ribs (or save them for stock!).

9. In a large pot, bring 3 quarts of water to a boil. Add the kale leaves and boil for 5-10 minutes, or until soft. Drain thoroughly and let cool slightly. Squeeze out any excess water from the kale to prevent a soggy lasagna.

10. In the same pot, bring another 3 quarts of water to a boil. Add the lasagna noodles and cook according to package directions (typically around 10 minutes). Drain and rinse with cold water to prevent sticking.

11. In a bowl, mix together the ricotta cheese, nutmeg, 1 cup of the mozzarella cheese, and the remaining salt and pepper (1/2 teaspoon each).

12. In a 9 x 13 inch baking pan, pour in 1/3 of the tomato sauce, spreading it evenly across the bottom.

13. Lay 3 lasagna noodles over the sauce. Top with half of the pureed butternut squash. Sprinkle 1/2 of the cooked kale over the squash.

14. Arrange 3 more noodles on top of the kale. Spread the ricotta cheese mixture evenly over the noodles. Top with the remaining kale leaves.

15. Arrange the final 3 noodles on top of the ricotta and kale. Cover with the remaining tomato sauce and the remaining mozzarella cheese.

16. Bake for 30 minutes, or until the cheese is melted and bubbly and the lasagna is heated through.

17. Let stand for 10 minutes before serving. This allows the lasagna to set slightly, making it easier to slice and serve.

Expert Tips & Tricks

• Roasting the Squash: Roasting the butternut squash instead of boiling it intensifies its sweetness and adds a lovely caramelized flavor.
• Kale Preparation: Be sure to thoroughly drain and squeeze the kale to remove excess moisture. This prevents the lasagna from becoming watery.
• Noodle Flexibility: If whole wheat lasagna noodles are not available, you can use regular lasagna noodles or even oven-ready noodles (follow package directions for oven-ready).
• Ricotta Enhancement: To add extra flavor to the ricotta filling, consider incorporating a tablespoon of chopped fresh herbs like basil or parsley.
• Preventing Sticking: Lightly spray the baking dish with cooking spray before layering the lasagna to prevent sticking.

Serving & Storage Suggestions

Serve this healthy lasagna warm, straight from the oven. It pairs beautifully with a simple green salad dressed with a light vinaigrette. For a heartier meal, serve alongside some crusty bread for soaking up the delicious sauce.

Leftovers can be stored in an airtight container in the refrigerator for up to 3-4 days. To reheat, cover the lasagna with foil and bake in a preheated oven at 350°F until heated through. You can also reheat individual portions in the microwave.

For longer storage, you can freeze the unbaked lasagna. Wrap it tightly in plastic wrap and then foil. It can be kept in the freezer for up to one month. To bake from frozen, add 1 1/4 hours to the baking time.
