I first made this brown butter pasta with butternut squash and sage when looking for a simple way to bring fall flavors to dinner. The nutty aroma from browning butter and the deep sweetness of caramelized squash is always a hit at our table.

Ingredients

  • Pasta: 350 g dried pasta (such as penne or fusilli), salt for pasta water
  • Vegetables: 1 medium butternut squash (about 700 g), peeled, seeded, and cut into 1 cm cubes; 2 cloves garlic, finely minced
  • Brown Butter & Sage: 60 g unsalted butter; 12 fresh sage leaves
  • Seasoning & Finishes: 40 g grated Parmesan cheese (plus extra for serving); freshly ground black pepper, to taste; 1/2 teaspoon chili flakes (optional); zest of 1/2 lemon (optional)

Instructions

Cook Pasta:
Bring a large pot of salted water to a boil. Cook pasta according to package instructions until al dente. Reserve 120 ml (1/2 cup) pasta water, then drain and set aside.

Recipe FAQs

How do I achieve the perfect brown butter for this dish?

Melt the butter over medium heat and cook while swirling the pan frequently until it turns golden brown and gives off a nutty aroma, about 2-3 minutes. Watch carefully to avoid burning.

Can I substitute butternut squash with another vegetable?

Yes, sweet potato is a great alternative that caramelizes similarly and pairs well with the brown butter and sage flavors.

What pasta types work best here?

Penne, fusilli, or other short pasta shapes are ideal as they hold the sauce well, but feel free to use your preferred variety, including whole wheat or gluten-free options.

How can I make this dish dairy-free?

Replace unsalted butter with plant-based alternatives and omit the Parmesan or use a vegan cheese substitute.

What is the purpose of reserving pasta water?

The reserved pasta water helps create a silky, cohesive sauce by loosening the mixture and allowing it to cling to the pasta evenly.

How do I add extra protein to this meal?

Incorporate cooked chickpeas or white beans when tossing the pasta to enhance the protein content without changing the flavor profile significantly.
