How to Make Roasted Butternut Squash Lasagna

  1. Preheat the oven to 425°F. Spray a baking sheet with cooking spray. Slice the butternut squash into ¼ inch thick planks after removing the ends, seeds, and skin. Toss with 1 tablespoon of olive oil, salt, and pepper. Bake for 15 minutes until just tender, then let cool.

  2. Sauté the garlic. Heat the remaining tablespoon of olive oil in a pan over medium heat. Add minced garlic and cook for 1-2 minutes until fragrant. Include the spinach and sauté until wilted, then remove from heat and set aside.

  3. Make the sauce. In a medium saucepan over medium heat, melt the butter and whisk in the flour for about a minute. Gradually whisk in the plant-based milk, around ½ cup at a time. Add the nutmeg and bay leaf, simmering on low for 3-5 minutes until thickened.

  4. Mix the cheese. In a medium bowl, combine ricotta, lemon zest, sage, rosemary, parmesan, mozzarella, salt, and pepper. Stir until well combined, creating a creamy filling.

  5. Layer the lasagna. Reduce the oven temperature to 400°F and spray a 9×13 baking dish with cooking spray. Start with a ladle of white sauce, then add a layer of no-cook noodles, butternut squash, sautéed spinach, and the ricotta mixture. Repeat the layers and finish with a final layer of noodles topped with the remaining sauce and parmesan cheese.

  6. Bake for 35 minutes on the middle rack until the top is golden brown and bubbling. Remove from the oven and allow to cool for at least 30 minutes to set before serving.

Optional: Garnish with fresh herbs for an extra pop of flavor.

Make Ahead Options

This Roasted Butternut Squash Lasagna is a fantastic choice for meal prep, allowing you to enjoy homemade comfort without the last-minute rush! You can prepare the entire lasagna up to 24 hours in advance. Simply follow the layering process, cover it tightly with plastic wrap or foil, and refrigerate until you’re ready to bake.

When you’re ready to serve, simply preheat your oven to 400°F and bake for 35 minutes. This make-ahead method ensures you can savor restaurant-quality flavors right at home, making busy weeknights a breeze!

How to Store and Freeze Roasted Butternut Squash Lasagna

Fridge: Store leftover lasagna in an airtight container in the refrigerator for up to 3 days. Reheat individual portions in the microwave or oven until warmed through.

Freezer: You can freeze the lasagna before or after baking. Wrap it tightly in plastic wrap and then aluminum foil; it keeps well for up to 3 months.

Reheating: If frozen, thaw overnight in the fridge before reheating. Bake at 375°F for about 30-40 minutes until heated through. This Roasted Butternut Squash Lasagna remains delicious even after freezing!

Serving Suggestion: Add fresh herbs or a sprinkle of cheese as you reheat to revive the flavors and elevate the dish for a delightful meal.

Tips for the Best Roasted Butternut Squash Lasagna

  • Proper Squash Prep: Cut the butternut squash planks evenly to ensure they cook uniformly and provide a consistent texture in your lasagna.

  • Avoid Watery Layers: Drain excess moisture from the sautéed spinach before layering; this prevents a soggy lasagna, ensuring each bite is perfectly rich and satisfying.

  • Layering Technique: Start and end with sauce layers when assembling your lasagna. This helps to keep the noodles moist while ensuring a delightful cheesy crust on top.

  • Cooling Time: Let your lasagna cool for at least 30 minutes before serving. This helps the layers set, making it easier to slice and serve without falling apart.

  • Maximize Flavor: Feel free to experiment with additional herbs or spices in the ricotta mixture. Adding a pinch of red pepper flakes can give the roasted butternut squash lasagna a pleasant kick!

Roasted Butternut Squash Lasagna Variations

Feel free to get creative and personalize your lasagna with these delicious twists!

  • Dairy-Free: Substitute ricotta with a cashew or tofu-based alternative for a creamy, dairy-free version that doesn’t skimp on flavor. Add nutritional yeast for an extra cheesy taste!

  • Vegetable Medley: Add layers of thinly sliced zucchini or eggplant to incorporate even more nutrition and color. These veggies add moisture and a unique twist to each bite.

  • Gluten-Free: Use gluten-free lasagna noodles to ensure everyone can enjoy this delightful dish. The no-cook kind works perfectly to keep the convenience intact!

  • Pesto Punch: Swirl a couple of tablespoons of basil pesto into the ricotta mixture for a fresh, aromatic flavor that beautifully complements the butternut squash and spinach.

  • Extra Creamy: Amp up the creaminess by adding an extra cup of plant-based milk or mixing in some cream cheese into the sauce for an even richer taste sensation!

  • Meat Lover’s Delight: For those who crave a heartier dish, layer in cooked ground turkey or sausage between the squash and spinach layers, adding robust flavors without compromising the original recipe.

  • Spicy Kick: Sprinkle in some red pepper flakes among the layers for those who enjoy a little heat. It’s an exciting way to wake up the flavors in this comforting dish!
