To get the best texture, don't skip browning the zucchini — let it sit in the pan without stirring for those golden spots. Reserve more pasta water than you think you'll need (every batch behaves differently). Warm your serving bowls briefly under hot water to keep the creamy texture alive. Add lemon juice gradually — start with 2 tablespoons and adjust, as it's hard to fix an overly tart sauce. This pasta is best fresh, but leftovers keep in the fridge for up to 2 days; reheat in a skillet with a splash of water.
