Ingredients

For the Pasta

12 ounces pasta, such as rigatoni, fettuccine, pappardelle, or orecchiette
3 cups peeled and cubed butternut squash
2 tablespoons olive oil
1/2 teaspoon sea salt
1/4 teaspoon black pepper
1/2 teaspoon garlic powder
6 tablespoons unsalted butter
12 fresh sage leaves
2 garlic cloves, finely minced
1/2 cup grated parmesan cheese, plus more for serving
1/2 cup reserved pasta water, plus more as needed
1 teaspoon fresh lemon juice
1/2 teaspoon lemon zest, optional
Pinch of red pepper flakes, optional

For Finishing

Freshly grated parmesan
Extra crisp sage leaves
Black pepper
Drizzle of olive oil, optional

Instructions

Preheat the oven to 400°F. Line a baking sheet with parchment paper.
Add the cubed butternut squash to the baking sheet. Drizzle with olive oil and season with salt, black pepper, and garlic powder. Toss until evenly coated.
Roast the squash for 25–30 minutes, turning once halfway through, until tender and lightly caramelized.
Bring a large pot of salted water to a boil. Cook the pasta according to package directions until al dente. Reserve at least 1 cup of pasta water before draining.
While the pasta cooks, make the brown butter. Add butter to a large skillet over medium heat. Let it melt, foam, and begin to turn golden, stirring occasionally.
Add the sage leaves to the butter and cook for 1–2 minutes, until the sage is crisp and the butter smells nutty. Remove a few sage leaves for garnish if desired.
Add the minced garlic to the skillet and cook for 30 seconds, just until fragrant.
Add the cooked pasta to the skillet and toss gently in the brown butter.
Add the roasted butternut squash, parmesan cheese, lemon juice, lemon zest if using, and 1/2 cup reserved pasta water. Toss until the pasta is glossy and lightly coated, adding more pasta water as needed.
Taste and adjust seasoning with salt, black pepper, or red pepper flakes.
Serve warm with extra parmesan, crisp sage, and a light drizzle of olive oil if desired.

Tips for the Best Pasta

Roast the butternut squash until it is tender and lightly caramelized. This brings out its natural sweetness and adds depth to the final dish.

Watch the butter carefully as it browns. It should smell nutty and look golden, not dark or burnt.

Reserve more pasta water than you think you need. The starchy water helps the sauce cling beautifully to the pasta.

Use fresh sage if possible. It crisps beautifully in the butter and gives the dish its signature flavor.

Add lemon juice at the end to brighten the richness of the brown butter and parmesan.

Serving Ideas

Serve this pasta with a crisp green salad, roasted broccolini, garlic bread, marinated olives, or a simple citrus salad. It also pairs beautifully with a bowl of soup or a warm vegetable side for a more complete seasonal meal.

For an elevated presentation, plate the pasta in shallow bowls and finish each serving with parmesan, black pepper, crisp sage, and a few golden pieces of roasted squash on top.

Substitutions

Use sweet potato or pumpkin instead of butternut squash.

Try pecorino romano instead of parmesan for a sharper flavor.

You can add vegan butter and dairy-free parmesan for a dairy-free version.

Add spinach, kale, mushrooms, or caramelized onions for extra vegetables.

If preferred, Use gluten-free pasta if needed.

Don’t forget toasted walnuts, pecans, or pumpkin seeds for crunch.

Storage Notes

Store leftover pasta in an airtight container in the refrigerator for up to 3 days. Reheat gently in a skillet with a splash of water or broth to loosen the sauce.

This pasta is best served fresh, but the roasted butternut squash can be prepared up to 3 days ahead and stored separately in the refrigerator.
