Equipment
- Large pot For boiling pasta; at least 6-quart capacity
- Large skillet or sauté pan At least 12 inches wide; for building the cream sauce
- Colander For draining the cooked pasta
- Microplane or fine grater For lemon zest and freshly grating Parmesan
- Wooden spoon or silicone spatula For stirring the sauce
- Measuring cups and spoons
- Ladle or heatproof measuring cup For reserving pasta water before draining
- Tongs For tossing the pasta in the sauce
Ingredients
- 12 oz spaghetti or linguine 340g; long thin pasta works best
- 3 tbsp unsalted butter
- 4 garlic cloves minced
- 2 tbsp extra virgin olive oil
- 1 cup heavy cream 240ml; whole milk may be substituted for a lighter sauce
- 1/2 cup reserved pasta water 120ml; reserved before draining pasta
- lemon 1 large lemon, zested; zest before juicing
- 3 tbsp fresh lemon juice from 1 large lemon, seeds removed; about 45ml
- 1 cup freshly grated Parmesan cheese 100g; plus more for serving. Use Parmigiano Reggiano for best results — do not use pre-grated
- 1/2 tsp red pepper flakes optional
- salt to taste; for pasta water and sauce
- freshly ground black pepper to taste
For Garnish
- 2 tbsp fresh parsley finely chopped
- Parmesan cheese extra, for serving; freshly grated
Instructions
- Bring a large pot of generously salted water to a rolling boil over high heat. The water should taste pleasantly salty like light seawater.
- Zest the lemon using a Microplane, then halve and squeeze out 3 tablespoons of fresh juice, removing any seeds. Set the zest and juice aside in separate small bowls.
- Cook spaghetti or linguine according to package directions but pull it 1–2 minutes early (it will finish in the sauce). Before draining, reserve at least 1 cup of starchy pasta water, then drain — do not rinse.
- Heat olive oil and butter in a large skillet over medium heat until the butter melts and foams. Add minced garlic (and red pepper flakes if using) and cook, stirring frequently, for 1–2 minutes until fragrant and just barely golden.
- Pour in the heavy cream and stir in the lemon zest. Bring to a gentle simmer over medium heat and cook for 3–4 minutes, stirring occasionally, until the sauce has thickened slightly and coats the back of a spoon.
- Reduce heat to low and stir in the freshly grated Parmesan in 2–3 additions, allowing each to melt fully before adding more. Add the fresh lemon juice, stir to combine, then season with salt and black pepper to taste.
- Add the drained pasta to the skillet and toss with tongs to coat, adding reserved pasta water a splash at a time until the sauce is silky, fluid, and clings to every strand.
- Divide pasta among four warmed bowls and top with freshly chopped parsley and extra grated Parmesan. Add a crack of black pepper and serve immediately.
Notes
- Always use fresh lemon juice — bottled juice lacks the bright, vibrant flavor this dish needs.
- Do not skip reserving the pasta water. The starch is essential for emulsifying the sauce into a silky, creamy texture.
- Grate Parmesan fresh from a block. Pre-grated cheese contains anti-caking agents that prevent smooth melting and can make the sauce grainy.
- Pull the pasta 1–2 minutes before fully cooked — it finishes cooking in the sauce and will reach perfect al dente texture.
- Keep heat on low when adding Parmesan. High heat causes the cheese proteins to seize, resulting in a greasy or broken sauce.
- To add protein, top with sautéed shrimp, grilled chicken, or pan-seared salmon before serving.
- For a lighter version, substitute half-and-half for the heavy cream and reduce butter by 1 tablespoon. The sauce will be slightly thinner but still flavorful.
- Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently in a skillet over low heat with a splash of water or cream to loosen the sauce.
- This dish does not freeze well — the cream sauce tends to separate upon thawing. Enjoy fresh for best results.
- For a gluten-free version, substitute your favorite gluten-free pasta. All other ingredients in this recipe are naturally gluten-free.
