-

Directions
-
Prepare the oven and ingredients
Begin by preheating your oven to 375°F (190°C). While the oven warms, lightly grease a 9×13-inch baking dish with olive oil, ensuring every corner is coated to prevent the lasagna from sticking. This small step will also help the flavors meld beautifully as the lasagna bakes. Gather all your vegetables and cheeses, and have them ready to streamline the cooking process. Prepping in advance reduces stress and allows you to focus on layering flavors. -
Roast the butternut squash
Place the peeled and cubed butternut squash in a large mixing bowl. Drizzle with one tablespoon of olive oil, then season with salt, pepper, and half of the thyme and rosemary. Toss gently to coat every piece evenly. Spread the squash in a single layer on a baking sheet, making sure the pieces are not overcrowded, which ensures even roasting. Roast in the preheated oven for 25–30 minutes, stirring halfway through. The squash should be tender when pierced with a fork and slightly caramelized at the edges. Roasting brings out its natural sweetness and deepens the flavor, providing a rich, hearty base for the lasagna. -
Sauté the mushrooms and onions
While the squash roasts, heat the remaining olive oil in a large skillet over medium heat. Add the diced onion and sauté for 3–4 minutes until it becomes soft and translucent. Next, add the mushrooms and cook until they release their moisture and become lightly browned. This process intensifies their earthy flavor. Stir in the minced garlic, remaining thyme, rosemary, and a pinch of nutmeg, cooking for an additional minute to allow the aromas to infuse. The combination of herbs and spices complements the sweetness of the roasted squash perfectly. -
Wilt the spinach
Add the chopped fresh spinach to the skillet and stir until it just begins to wilt. Be careful not to overcook it, as the spinach will continue to soften in the oven. Once wilted, remove the skillet from heat and set aside. This ensures the spinach retains its vibrant green color and fresh flavor. -
Prepare the cheese mixture
In a medium mixing bowl, combine the ricotta cheese with half of the grated Parmesan cheese. Season lightly with salt and pepper, then stir until smooth and creamy. The ricotta mixture acts as a rich, silky layer between the vegetables and pasta, binding the flavors together. For an extra touch, you can add a small pinch of nutmeg or a teaspoon of fresh herbs, enhancing the aromatic complexity of the lasagna. -
Cook the lasagna noodles
If using traditional lasagna noodles, cook them according to package instructions until al dente. Be careful not to overcook, as they will continue to cook in the oven. Drain the noodles carefully and lay them flat on a clean kitchen towel to prevent sticking. For a faster option, no-boil noodles can be used, but slightly overlapping them may be necessary to ensure full coverage. -
Assemble the layers
Begin assembly by spreading a thin layer of marinara sauce on the bottom of your prepared baking dish. Lay down the first layer of noodles, making sure they cover the sauce evenly. Add a layer of roasted squash, followed by a generous portion of the sautéed vegetables. Spoon dollops of the ricotta mixture evenly across the top and sprinkle with a portion of mozzarella cheese. Continue layering in this order—noodles, squash, vegetables, ricotta, mozzarella—until all ingredients are used. Finish with a final layer of noodles, sauce, and a generous topping of mozzarella and remaining Parmesan cheese. This layering ensures every bite is a perfect combination of creamy, cheesy, and vegetable-packed goodness. -
Optional cream layer
For an extra creamy and indulgent texture, drizzle ½ cup of heavy cream evenly over the top layer before baking. This step adds richness and helps achieve a golden, bubbly finish. -
Bake the lasagna
Cover the dish with aluminum foil and bake in the preheated oven for 25 minutes. Remove the foil carefully and bake for an additional 15–20 minutes, or until the cheese on top is melted, golden brown, and bubbly. Baking in two stages prevents the top layer from burning while ensuring the lasagna heats evenly throughout. -
Rest and serve
Once baked, remove the lasagna from the oven and let it rest for at least 10 minutes before slicing. This resting period allows the layers to set, making serving easier and preventing the filling from spilling out. Garnish with fresh parsley for a pop of color and extra freshness, then serve warm and enjoy the comforting flavors of autumn in every bite.

Frequently Asked Questions
Can I make this recipe vegan?
Yes! Transforming this Autumn Harvest Veggie Lasagna into a vegan-friendly dish is simple. Replace the ricotta cheese with a plant-based ricotta alternative made from cashews, tofu, or almonds, which provides a creamy texture similar to traditional ricotta. Swap the mozzarella for a vegan cheese that melts well—look for brands labeled “melty” or “shreddable” for best results. Instead of heavy cream, use a plant-based cream or even unsweetened oat or soy milk thickened slightly with cornstarch. By making these substitutions, you maintain the rich, creamy layers of the lasagna while keeping it completely plant-based. Additionally, you can enhance the flavor with extra herbs like sage or thyme, which complement the roasted vegetables beautifully.
Can I use pre-cooked or frozen vegetables?
Absolutely. Using pre-cooked or frozen vegetables can save time and still deliver excellent flavor. If using frozen butternut squash, mushrooms, or spinach, it’s important to thaw them fully and drain any excess moisture before layering. Excess water can make the lasagna watery, affecting the texture. For pre-cooked vegetables, ensure they are not overly soft or mushy, as they will cook further in the oven. Roasting frozen squash or sautéing frozen mushrooms before assembly helps intensify their flavor and ensures the layers remain distinct.
How do I prevent the lasagna from being watery?
A common challenge with vegetable lasagnas is excess liquid. To avoid this, make sure to drain or pat dry all vegetables before layering. Roasting vegetables like butternut squash concentrates their natural sweetness while reducing water content. Using a thick, well-simmered marinara sauce also helps maintain the proper consistency, preventing the noodles from becoming soggy. Additionally, avoid overlapping noodles too heavily, as trapped moisture can accumulate and cause watery layers. If needed, slightly reduce the amount of sauce for each layer while still keeping the lasagna flavorful.
Can I assemble this lasagna ahead of time?
Yes, this recipe is perfect for make-ahead cooking. Assemble the lasagna a day in advance and cover it tightly with plastic wrap or foil. Store it in the refrigerator until ready to bake. When you’re ready, bake as instructed, adding an extra 10–15 minutes if the lasagna is cold from the fridge. Preparing it ahead not only saves time on busy evenings but also allows the flavors to meld, resulting in an even more delicious and cohesive dish.
