How to Make Butternut Squash Lasagna with Mushrooms and Spinach

Step 1: Prepare the Butternut Squash

Start by peeling and cubing the butternut squash, then toss with olive oil, salt, and pepper. Roast on a baking sheet at 400°F (200°C) for about 25-30 minutes until tender and caramelized. This roasting step deepens the flavor and makes the squash wonderfully creamy for layering.

Step 2: Sauté the Mushrooms and Spinach

In a large skillet, heat olive oil and sauté finely chopped onions and garlic until fragrant. Add chopped mushrooms and cook until their moisture evaporates and they turn golden brown. Toss in fresh spinach last, allowing it to wilt slightly, then season with salt, pepper, and herbs like thyme or sage.

Step 3: Prepare the Cheese Mixture

In a bowl, combine ricotta cheese with a handful of grated Parmesan, a pinch of salt, pepper, and some chopped fresh herbs. This mixture will add richness and creaminess to the layers without overpowering the vegetables.

Step 4: Boil the Lasagna Noodles

Cook the lasagna noodles in salted boiling water until al dente, then drain and lay them flat on a towel to prevent sticking. Proper noodle texture is key so your lasagna isn’t mushy but holds together perfectly.

Step 5: Assemble the Lasagna

In a baking dish, start with a thin layer of sauce or olive oil, then place noodles. Spread a layer of ricotta cheese mixture, followed by roasted butternut squash, sautéed mushrooms and spinach, then sprinkle mozzarella and Parmesan. Repeat the layers until you reach the top, finishing with a generous cheese layer for a bubbly, golden crust.

Step 6: Bake to Perfection

Cover lightly with foil and bake at 375°F (190°C) for about 30 minutes. Remove the foil in the last 10 minutes to let the top brown beautifully. Allow the lasagna to rest for 10-15 minutes before slicing to let the layers set nicely for serving.

Pro Tips for Making Butternut Squash Lasagna with Mushrooms and Spinach

• Don’t Skip Roasting: Roasting the squash caramelizes its sugars and brings out deeper flavors than boiling or steaming.
• Drain Mushrooms Well: Mushrooms release moisture, so cook until all liquid evaporates to avoid a watery lasagna.
• Use Fresh Herbs: Fresh thyme or sage instantly elevate the flavor, giving a nice aroma and complexity.
• Rest After Baking: Letting the lasagna cool slightly helps it firm up and makes serving cleaner and easier.
• Layer Thoughtfully: Spread fillings in even layers to ensure each bite offers a perfect balance of squash, mushrooms, spinach, and cheese.

How to Serve Butternut Squash Lasagna with Mushrooms and Spinach

Garnishes

Sprinkle freshly chopped basil or parsley over the warm lasagna for a burst of color and a fresh herbal note. A drizzle of high-quality extra virgin olive oil or a dusting of extra Parmesan can also add a lovely finishing touch.

Side Dishes

To complement the richness of the lasagna, serve with a crisp green salad dressed lightly with lemon and olive oil or roasted seasonal vegetables for added texture and nutrition.

Creative Ways to Present

Serve individual portions in small cast iron skillets to keep the lasagna warm and perfectly portioned. Alternatively, create mini lasagna cups using muffin tins for a fun, bite-sized party appetizer.

Make Ahead and Storage

Storing Leftovers

Wrap leftover butternut squash lasagna tightly with plastic wrap or store in an airtight container in the refrigerator. It stays fresh for up to 3-4 days, making it a convenient next-day meal.

Freezing

This recipe freezes well! Assemble the lasagna in a freezer-safe dish, cover tightly with foil, and freeze for up to 3 months. When ready, thaw overnight in the refrigerator before baking.

Reheating

Reheat individual slices in the microwave or warm the entire dish in the oven at 350°F (175°C) until heated through. Cover with foil to prevent drying out and remove foil towards the end to re-melt the cheese.

FAQs

Can I use frozen spinach instead of fresh?

Yes, you can substitute frozen spinach but be sure to thaw and thoroughly squeeze out excess moisture before adding to prevent a watery lasagna.

Is it necessary to roast the butternut squash first?

Roasting is highly recommended as it enhances sweetness and texture, creating a creamy layer that boiling or steaming doesn’t achieve.

Can I prepare this recipe ahead of time?

Absolutely! You can assemble the lasagna a day in advance and keep it refrigerated until ready to bake, which actually helps flavors meld together beautifully.

What is the best cheese mix for this recipe?

A combination of ricotta, mozzarella, and Parmesan provides creaminess, meltiness, and sharpness, achieving perfect balance and texture.

How can I make this recipe vegan-friendly?

Replace the cheeses with vegan ricotta and mozzarella alternatives or cashew cream, and use olive oil instead of butter to keep it fully plant-based.
