Step‑by‑Step Instructions for Creamy Butternut Squash and Spinach Lasagna
Step 1: Prepare the Butternut Squash Filling
Begin by preheating your oven to 400°F (200°C). Roast the diced butternut squash for 25-30 minutes until tender and slightly caramelized, allowing natural sweetness to develop. Once cooled, blend the squash with ricotta cheese, milk, salt, and a sprinkle of nutmeg in a food processor until creamy and smooth. Set this delightfully creamy mixture aside for layering.
Step 2: Make the Spinach Filling
In a medium bowl, combine the drained fresh spinach with ricotta, half of the shredded mozzarella, minced garlic, and a pinch of salt and pepper. Stir thoroughly until all ingredients are well integrated and the mixture has a vibrant green hue. Taste and adjust seasoning if necessary, ensuring it’s flavorful and aromatic for your layers in the Butternut Squash and Spinach Lasagna.
Step 3: Cook the Lasagna Noodles
Bring a large pot of salted water to a boil. Add lasagna noodles and cook them for about 8-10 minutes or until al dente, stirring occasionally to prevent sticking. Once cooked, drain the noodles and quickly rinse them under cold water to stop the cooking process. Lay them flat on a clean surface or parchment paper to prevent them from gluing together as you build the lasagna.
Step 4: Layer the Lasagna
Grease a 9×13 inch baking dish with a little olive oil to prevent sticking. Start layering by spreading a thin layer of the butternut squash filling at the bottom, followed by a layer of noodles. Repeat the process: add the spinach filling, then more noodles, alternating until all fillings are used. Finish with a final layer of the butternut squash filling and top generously with the remaining mozzarella and Parmesan cheese.
Step 5: Bake the Lasagna
Cover the baking dish tightly with aluminum foil and place it in the preheated oven at 375°F (190°C). Bake for 30 minutes, allowing the flavors and textures to meld beautifully. After 30 minutes, remove the foil and continue baking for an additional 10 minutes until the cheese is golden and bubbly, creating a delicious crust that beckons you.
Step 6: Rest and Serve
Once baked, carefully take the lasagna out of the oven and allow it to rest for about 10 minutes. This resting period helps the layers set and makes slicing easier. Use a sharp knife to cut into squares, revealing the vibrant layers of your comforting Butternut Squash and Spinach Lasagna before serving. Enjoy a slice with a side salad or some crusty garlic bread for a fulfilling meal!

Make Ahead Options
These Butternut Squash and Spinach Lasagna layers make it a dream for meal prep enthusiasts! You can prepare the butternut squash filling (which keeps its creamy texture) and the spinach filling up to 24 hours in advance. Simply refrigerate them in airtight containers to maintain freshness. Additionally, you can cook the lasagna noodles, layer everything in the baking dish, and then cover tightly with foil; it can be kept in the fridge for up to 3 days. When you’re ready to bake, just pop it in the preheated oven straight from the fridge and increase the baking time by a few minutes to ensure it’s heated through. By prepping ahead, you’ll have a comforting, homemade dinner ready in no time, bringing joy back to your busy weeknights!

Butternut Squash and Spinach Lasagna Recipe FAQs
How do I choose ripe butternut squash?
Absolutely! When selecting butternut squash, look for one that feels heavy for its size, has a smooth and matte skin, and is free from any dark spots or blemishes. The color should be a uniform beige with a slight sheen, indicating it’s ripe. A stem that is dried out can also be a good sign of ripeness.
What’s the best way to store leftovers?
You can store your Butternut Squash and Spinach Lasagna in an airtight container in the fridge for up to 4 days. To maintain the vibrancy of the flavors, cover it tightly. If you’re not planning to eat it right away, consider freezing unbaked portions for up to 3 months. Wrap it well in plastic wrap, then foil to prevent freezer burn.
Can I freeze the lasagna? If so, how?
Absolutely! To freeze your butternut squash and spinach lasagna, prepare it up to the baking step. Wrap the unbaked lasagna tightly using plastic wrap, then cover it with foil to avoid freezer burn. When you’re ready to enjoy it, simply transfer it to the fridge to thaw overnight before baking, or bake it from frozen—just increase the cooking time by about 15-20 minutes.
Why is my lasagna watery?
Very! A common reason for watery lasagna is not draining your spinach sufficiently. To avoid this, after cooking, squeeze out excess moisture using a clean kitchen towel or paper towels. Additionally, ensure your butternut squash puree is blended smoothly and thick, as any excess water can contribute to the final texture. Layering too much sauce can also lead to a runny result—use just enough to moisten.
Can I use other greens instead of spinach?
Definitely! If you want to get a bit creative, you can substitute spinach with other greens like kale or Swiss chard. Just make sure to chop them finely and sauté briefly to reduce bitterness and ensure tenderness. This will add a new layer of flavor while keeping your lasagna healthy and packed with nutrients!
Is this recipe suitable for vegetarians?
You bet! This Butternut Squash and Spinach Lasagna is entirely vegetarian. For vegan diners, simply replace the cheese with dairy-free alternatives, like cashew ricotta or vegan mozzarella, and use plant-based milk. You can also skip the Parmesan topping and sprinkle nutritional yeast for a cheesy flavor enhancement.
