Ingredients
Method
- Boil. Cook pasta in well-salted water until al dente. Reserve 1.5 cups of pasta water before draining.
- Sauté. While pasta cooks, heat olive oil in a large skillet over medium heat. Add garlic and red pepper flakes and cook 30 seconds until fragrant.
- Mix. In a bowl, whisk together the ricotta, lemon juice, lemon zest, and half the parmesan until smooth.
- Toss. Add the drained pasta to the skillet, then pour the ricotta mixture over. Toss vigorously, adding pasta water a splash at a time until you get a silky, creamy sauce. Season with salt and pepper, top with basil and remaining parmesan.
Notes
Use whole milk ricotta for the creamiest sauce. Low-fat ricotta will taste grainy. Zest the lemons before juicing them. It's much easier to zest a whole lemon. The pasta water is essential. The starch helps the ricotta emulsify into a smooth sauce instead of clumping.
