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, 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 the pasta according to package instructions until al dente. Reserve 120 ml pasta water, then drain and set aside.
