Ingredients You’ll Need

The image shows a flat lay of cooking ingredients arranged on a white marbled surface. At the bottom right, a glass jar tipped over spills yellow penne pasta, which leads to a clear glass bowl filled with bright orange cubed cheese at the bottom left. Above the cheese, there is a small wooden bowl holding a single white egg. In the center, a clear glass bowl contains white creamy ricotta cheese, surrounded by small wooden bowls and glass containers holding grated cheese in two shades of pale yellow, fresh dark green spinach leaves, olive oil in a small glass bowl, and water in another glass bowl. Three small wooden bowls hold seasonings, one with a light beige powder, one with dark dried herbs, and one with red chili flakes. Two small glass jars with black tops labeled S and P, likely salt and pepper, are placed near the top right. The arrangement is tidy and well spaced, the colors bright against the white marbled background. Photo taken with an iphone --ar 4:5 --v 7

The magic of this Butternut Squash and Spinach Pasta Pie Recipe lies in its simple but thoughtfully chosen ingredients. Each one plays a unique role, whether it’s the creamy texture of ricotta, the mellow sweetness of butternut squash, or the vibrant green freshness of spinach. Together, they build layers of flavor and color that make this dish as pleasing to the eye as it is to the palate.

Large egg: Helps bind the ingredients and adds a rich, silky texture throughout the pie.
Ricotta cheese (1 cup): Provides a creamy, mild base that complements the vegetables beautifully.
Grated parmesan (1 cup, divided): Adds a nutty, savory kick, especially when sprinkled on top for a golden crust.
Shredded mozzarella (1 cup): Melts perfectly to give gooey, stringy goodness in every bite.
Water (1 1/4 cups): Keeps the pasta moist and helps create a tender texture inside the pie.
Olive oil (3 tablespoons, divided): Brings richness and a delicate fruity aroma; reserve some for drizzling to finish.
Garlic powder (1/2 teaspoon) or 3 cloves fresh garlic minced: Infuses the pie with warmth and subtle spice.
Crushed red pepper flakes (1/4 teaspoon): Adds a gentle heat to enliven the flavors without overpowering.
Dried thyme (1/2 teaspoon): Offers a bright herbal note, perfectly balancing the sweetness of the squash.
Kosher salt (1 teaspoon): Essential for seasoning, enhancing all the natural flavors in the dish.
Freshly ground black pepper (1/4 teaspoon): Adds just enough bite to keep things interesting.
Winter squash, cubed small (3 cups, about 1 pound): The star of the show, bringing sweetness and a velvety texture.
Baby spinach (5 ounces, roughly chopped): Provides freshness, color, and a mild earthy flavor that brightens the pie.
Penne pasta (8 ounces): Serves as the hearty base, holding all the delicious components together; lasagna noodles can work if broken into pieces.

How to Make Butternut Squash and Spinach Pasta Pie Recipe

Step 1: Prep Your Pan and Oven

Start by preheating your oven to 350°F. Taking a little time to line a nine-inch springform pan with parchment paper really pays off—it prevents sticking and helps you lift out the pie cleanly. I like folding two pieces in a plus sign shape so all sides are covered and the edges easily fold over later.

Step 2: Blend the Cheeses and Spices

In a large bowl, beat the egg first to ensure smooth mixing. Then add ricotta, half the parmesan, mozzarella, water, two tablespoons of olive oil, garlic powder, crushed red pepper flakes, thyme, salt, and pepper. Mix everything together until you have a silky, fragrant base that promises creamy, flavorful bites throughout the pie.

Step 3: Add Veggies and Pasta

Now, fold in the cubed butternut squash, chopped spinach, and cooked penne pasta. Give it a thorough stir using a sturdy wooden spoon or spatula. This is where the texture balance really comes alive — soft pasta meets tender squash, with vibrant leafy spinach scattered throughout.

Step 4: Assemble the Pie

Pour your mixture into the prepared springform pan, spreading it evenly and pressing gently to smooth the surface. Next, sprinkle the remaining parmesan over the top. Carefully fold the parchment edges up and over the filling, then cover tightly with foil to trap moisture and ensure even cooking.

Step 5: Bake Your Pasta Pie

Place the pan on a baking sheet to catch any drips. Bake covered for 1 hour—it’s slow baking that softens the squash perfectly. Then remove the foil, fold down those parchment edges, drizzle the leftover tablespoon of olive oil on top, and bake uncovered for another 30 minutes until the surface develops golden, slightly crispy spots.

Step 6: Cool and Serve

Once out of the oven, let the pie sit for 30 minutes to firm up; this resting time makes slicing much easier while allowing flavors to settle beautifully. To serve, remove the springform ring and gently slide the pie out using the parchment paper as a sling. Cut into wedges and get ready to enjoy!

Garnishes

Simple garnishes like fresh basil leaves or a sprinkle of extra parmesan make a lovely finishing touch both visually and flavor-wise. A light drizzle of good-quality olive oil or a few cracked black pepper flakes on each slice really brings out the cheesy richness.

Side Dishes

This pasta pie pairs wonderfully with crisp salads—think arugula with lemon vinaigrette or a simple crunchy cucumber salad. Roasted or grilled vegetables can also round out the meal without competing with the hearty pasta flavors.

Creative Ways to Present

For a dinner party, serve individual wedges on colorful plates with a dollop of herbed Greek yogurt or a tangy tomato chutney on the side. You can also cut the pie into smaller bites for appetizers or party platters, garnished with microgreens for an elegant touch.

Make Ahead and Storage

Storing Leftovers

After enjoying your Butternut Squash and Spinach Pasta Pie, store leftovers tightly covered in the fridge for up to 3 days. The flavors actually deepen overnight, making leftovers just as delightful as the fresh bake.

Freezing

If you want to make this dish ahead, it freezes beautifully. Simply assemble and bake the pie fully, cool it completely, then wrap it tightly in plastic wrap followed by foil before freezing. It will keep for up to 2 months.

Reheating

To reheat, thaw the frozen pie overnight in the fridge if needed, then warm it in a 350°F oven for about 20-30 minutes until heated through and the cheese has softened again. Avoid microwaving if you want to retain the texture and avoid sogginess.

FAQs

Can I substitute another type of squash for butternut?

Absolutely! Kabocha or acorn squash can work well in this recipe, but keep in mind their moisture and sweetness levels differ slightly, which might affect baking time and flavor balance.

Do I need to pre-cook the pasta?

No need here because the water in the mixture allows the pasta to cook fully while baking. Using dried pasta straight into the mix saves time and infuses everything with flavor as it softens.

Can this recipe be made vegan?

You can adapt it by using vegan ricotta and mozzarella alternatives and replacing the egg with a flax or chia egg. Just note the texture and flavor will differ but still be deliciously satisfying.

Is it possible to use fresh garlic instead of garlic powder?

Yes, fresh garlic adds a vibrant punch. Use about 3 cloves minced to replace the garlic powder, adjusting to your taste.

How do I cleanly remove the pie from the springform pan?

Using parchment paper lining makes this super easy. After baking and cooling, run a thin spatula around the edges before releasing the springform ring, then gently lift the pie out by the parchment for perfect slices.
