Ingredients
Method
- Bring a large pot of salted water to a boil. Meanwhile, heat the olive oil and butter in a large skillet over medium-high heat. Add the zucchini, season with salt and pepper, and cook until golden, about 5 minutes. Stir in the garlic and red pepper flakes and cook 30 seconds.
- Add the spaghetti to the boiling water and cook until al dente, 8 to 10 minutes. Reserve 1 cup of pasta water, then drain.
- Transfer the drained pasta to the skillet with the zucchini. Remove from heat. Add the lemon zest, lemon juice, half the Parmesan, and a splash of pasta water. Toss vigorously for 1 to 2 minutes, adding more water as needed, until the sauce coats the pasta.
- Divide among bowls, top with the remaining Parmesan, basil, and black pepper. Serve hot.
Notes
For the best texture, cook the zucchini over high heat and avoid crowding the pan. If doubling the recipe, cook the zucchini in batches. The pasta is best right after tossing, but leftovers can be reheated gently with a splash of water.
