Ingredients:
Kosher salt
1 pound dry spaghetti
1/4 cup olive oil
2 teaspoons minced rosemary
1/2 teaspoon crushed red pepper
6 garlic cloves, thinly sliced
1 medium shallot, thinly sliced
2 medium zucchini, coarsely grated
Freshly ground black pepper
4 ounces feta, crumbled
1/2 cup fresh basil leaves, torn
2 tablespoons freshly squeezed lemon juice
Directions:
Bring a large pot of salted water to a boil. Add the spaghetti and cook until al dente according to package directions. Drain, reserving 1 cup pasta water.
Meanwhile in a large high-sided skillet, heat the olive oil over medium-high heat. Add the rosemary, crushed red pepper, garlic, and shallot and cook until softened, 2-3 minutes. Add the zucchini with a heavy pinch of salt and pepper and cook down until jammy, 4-5 minutes.
Add the drained spaghetti, pasta water, and feta, then cook, stirring constantly, until a glossy sauce forms, about 2 minutes. Stir in the basil and lemon juice. Taste and adjust seasoning with salt and pepper, then serve.
