How to Make Butternut Squash Lasagna with Mushrooms and Spinach

Step 1: Roast and Puree the Butternut Squash

Start by peeling and cubing your butternut squash. Toss the cubes in olive oil, salt, and pepper, then roast in a preheated oven at 400°F (200°C) for about 25-30 minutes until tender and caramelized. Once cooled slightly, puree the squash in a food processor or blender until smooth and creamy. This puree forms a luscious base layer and adds natural sweetness to the lasagna.

Step 2: Sauté the Mushrooms, Spinach, and Aromatics

In a large skillet, heat olive oil over medium heat. Add finely chopped onions and garlic, cooking until fragrant and translucent. Then add sliced mushrooms and cook until they’re soft and slightly browned. Finally, toss in the spinach and cook until just wilted. Season with salt, pepper, fresh sage, and thyme to enhance the flavor profile of the vegetable filling.

Step 3: Prepare the Ricotta Mixture

In a bowl, combine ricotta cheese with a little milk or cream if you want a lighter consistency. Mix in some grated Parmesan, salt, pepper, and a pinch of nutmeg for warmth. This creamy mixture adds another layer of texture and richness to the lasagna.

Step 4: Assemble the Layers

In a greased baking dish, start with a thin layer of butternut squash puree. Next, layer lasagna noodles followed by the ricotta mixture, the sautéed mushrooms and spinach, and a sprinkle of mozzarella. Repeat these layers until you run out of ingredients, finishing with a generous topping of mozzarella and Parmesan cheese for a golden crust.

Step 5: Bake to Perfection

Cover the dish with foil and bake in a preheated oven at 375°F (190°C) for 30 minutes. Remove the foil and bake for an additional 10-15 minutes until the cheese is bubbly and golden brown. Allow the lasagna to cool for at least 10 minutes before slicing to ensure clean, perfect layers.

Pro Tips for Making Butternut Squash Lasagna with Mushrooms and Spinach

• Roast squash in advance: This saves time on busy days and enhances the squash’s caramelized flavor.
• Use no-boil noodles: They absorb moisture better and simplify the assembly process.
• Don’t over-sauté spinach: Just wilt it lightly to keep its vibrant color and fresh taste.
• Layer thoughtfully: Spread ingredients evenly for balanced flavors and moist lasagna.
• Let it rest: Cooling before serving helps the lasagna set, improving texture and slice-ability.
