How to Make Butternut Squash and Spinach Lasagna

Step 1: Roast the Butternut Squash

Preheat your oven and toss peeled, cubed butternut squash with olive oil, salt, and a sprinkle of black pepper. Spread it evenly on a baking tray and roast until tender and caramelized, about 25 minutes. Roasting brings out the natural sweetness that forms the signature base of this lasagna.

Step 2: Sauté Aromatics and Spinach

While the squash roasts, heat olive oil in a pan and gently sauté diced onions and minced garlic until fragrant and translucent. Add fresh spinach and cook just until wilted. Stir in vegetarian Worcestershire sauce (natural), nutmeg, and pepper to build flavor depth.

Step 3: Prepare the Sauce with Natural Gelling Agent

Make a creamy sauce by combining plant-based milk with a natural gelling agent in a saucepan over medium heat. Whisk until it thickens to a luscious consistency, then season with salt and pepper. This velvety layer will bind the other ingredients and add moist richness.

Step 4: Assemble the Layers

Start with a thin coat of sauce on the bottom of your baking dish. Add a layer of cooked pasta sheets, followed by roasted butternut squash, sautéed spinach mixture, dollops of plant-based cheese, and more sauce. Repeat until all ingredients are used, finishing with a pasta layer topped with a generous sprinkle of grated plant-based Parmesan cheese.

Step 5: Bake to Perfection

Cover the assembled lasagna with foil and bake in the oven at a moderate temperature for 30-35 minutes. Remove the foil for the last 10 minutes to allow the top to brown lightly and bubble enticingly. Let it rest a few minutes before serving for best texture.

Pro Tips for Making Butternut Squash and Spinach Lasagna

  • Roast squash evenly: Cut evenly-sized cubes to ensure uniform roasting and caramelization.
  • Don’t over-sauté spinach: Just wilt to keep it vibrant and fresh-tasting.
  • Use fresh herbs: Fresh sage or thyme elevate the layers with bright herbal notes.
  • Layer sauces thinly: Too much sauce can turn the lasagna soupy; aim for balance.
  • Rest before serving: Cooling for at least 10 minutes helps the lasagna set for cleaner slices.

How to Serve Butternut Squash and Spinach Lasagna

Garnishes

Add a sprinkle of chopped fresh parsley or basil for a lively color pop and fresh aroma that complements the warm, creamy flavor inside.

Side Dishes

Serve alongside a crisp green salad with a lemon and olive oil dressing or some roasted seasonal vegetables to keep the meal balanced and vibrant.

Creative Ways to Present

For a special occasion, make individual portions using ramekins or mini cast iron skillets. Layer and bake as usual, then garnish with microgreens for an elegant touch.

Make Ahead and Storage

Storing Leftovers

Keep leftover lasagna covered in the fridge for up to 3-4 days in an airtight container. The flavors deepen beautifully overnight.

Freezing

Wrap the entire lasagna tightly with plastic wrap and foil or portion into freezer-safe containers. Freeze for up to 2 months for a quick future meal.

Reheating

Thaw frozen portions overnight in the fridge, then reheat in the oven covered with foil to retain moisture, or microwave individual slices on medium power for a creamy warm-up.

FAQs

Can I use frozen spinach instead of fresh?

Yes, but be sure to thaw and squeeze out excess water well to avoid soggy layers.

How do I ensure the lasagna stays creamy and not watery?

Use the right amount of natural gelling agent in the sauce and avoid overloading with watery spinach or squash juices.
