Ingredients

1 pound pasta (spaghetti, linguine, or fettuccine)

2 large zucchini (about 1.5 pounds), sliced into 1/4-inch thick rounds

1 large yellow onion, thinly sliced

4 cloves garlic, minced

1/4 cup olive oil, extra virgin

2 tablespoons unsalted butter

1/2 cup vegetable broth or reserved pasta water

1/4 cup grated Parmesan cheese, plus more for serving

2 tablespoons chopped fresh basil, plus more for garnish

1 teaspoon red pepper flakes (optional)

Salt and freshly ground black pepper, to taste

1/4 cup toasted pine nuts (optional, for garnish)

Instructions

  1. Prepare the zucchini, onion, and garlic.

  2. Heat olive oil and butter in a skillet. Sauté onion with salt for 8–10 minutes.

  3. Add zucchini, season with salt and pepper, and cook for 20–25 minutes until caramelized. Add broth if needed to prevent sticking.

  4. Stir in garlic and red pepper flakes. Cook 1–2 minutes.

  5. Cook pasta in salted water until al dente. Reserve 1/2 cup water, then drain.

  6. Add pasta to skillet with caramelized vegetables. Toss with reserved liquid.

  7. Stir in Parmesan and basil until creamy. Adjust seasoning.

  8. Serve hot, garnished with extra cheese, basil, and pine nuts if desired.

Notes

  • Use day-old pasta water or broth to loosen the sauce.
  • Make it vegan with plant-based butter and vegan cheese.
  • Add lemon zest for brightness.
  • Reheat gently to retain texture.
  • Zucchini noodles can be used instead of pasta for a low-carb version.
