Spaghetti al Limone is a simple Italian lemon pasta with a fresh, bright flavor and a wonderfully creamy texture—without any heavy cream. The sauce is made with fresh lemon juice and zest, extra virgin olive oil and starchy pasta water.
The secret to creamy lemon spaghetti is the cooking technique. The pasta is drained before it is fully cooked and then finished directly in the pan with the lemon sauce and a little cooking water. In Italian, this method is called “risottare la pasta”, because the pasta finishes cooking much like a risotto, gradually absorbing the liquid while releasing starch.
As the spaghetti cooks in the pan, the starch helps the lemon juice, olive oil, and cheese emulsify into a silky sauce that coats every strand. This is what gives Spaghetti al Limone its characteristic creaminess without the need for cream.
This style of lemon pasta is closely associated with Campania and the Amalfi Coast, an area famous for its exceptionally fragrant lemons. Since both the juice and zest are essential to the recipe, always choose an untreated or organic lemon with a flavorful peel.
Spaghetti are my favorite choice for this recipe, but linguine or tagliolini also work beautifully. Serve it immediately for a quick summer meal or an elegant first course made with just a handful of simple Italian ingredients.

Why This Recipe Works
Creamy without heavy cream. The sauce becomes smooth and silky thanks to the starch released by the pasta, together with butter, extra virgin olive oil, lemon juice, and pasta cooking water.

Fresh and simple. A handful of ingredients is enough to create a bright, aromatic pasta where the flavor of fresh lemon really stands out.
Quick to prepare. Spaghetti al Limone comes together in about the time it takes to cook the pasta, making it ideal for an easy lunch, a weeknight dinner, or a light summer meal.
Ingredients
Prep Time: 10 Min | Cook Time: 10 Min | Servings: 4
- 350 g (12 oz) spaghetti
- 40 g (3 tablespoons) unsalted butter
- 1 large organic or untreated lemon
- 1 garlic clove
- 1 tablespoon extra virgin olive oil
- 1 tablespoon finely chopped fresh parsley
- 1.5 liters (about 6⅓ cups) water
- ½ tablespoon coarse salt
How to Make spaghetti al limone
Step 1) - Wash and dry the lemon thoroughly. Finely grate the zest, taking care to remove only the yellow part and avoid the bitter white pith underneath. Then squeeze the lemon juice and set both the zest and juice aside.
Step 2) - Place the butter, extra virgin olive oil, and most of the lemon zest in a large skillet. Reserve a little zest for serving.
Melt the butter over low heat, then add the lemon juice and the whole garlic clove. Cook gently for about 4 to 5 minutes, stirring occasionally. Keep the heat low so the garlic and lemon zest don't burn.
Step 3) - Meanwhile, bring 1.5 liters (about 6⅓ cups) of water to a boil and add the coarse salt. Cook the spaghetti, but drain them well before they reach al dente, since they will finish cooking directly in the lemon sauce.
Before draining, reserve plenty of the starchy pasta cooking water.
Transfer the partially cooked spaghetti directly to the skillet with the lemon sauce.
Step 4) - Add one ladleful of the reserved pasta cooking water and continue cooking the spaghetti over medium heat, tossing and stirring frequently.
As the pasta finishes cooking, it will release more starch and gradually absorb the lemon sauce. Add more cooking water, a little at a time, whenever the pan begins to look dry.
Continue until the spaghetti are al dente and the liquid has emulsified with the butter and olive oil into a smooth, glossy sauce that coats the pasta.
Remove the garlic clove and serve the Spaghetti al Limone immediately. Finish with the reserved lemon zest and finely chopped fresh parsley.
Tips for the Best Spaghetti al Limone
Choose a fragrant, untreated lemon. Since this recipe uses both the juice and the zest, choose a fresh, firm organic or untreated lemon and wash it thoroughly before using. Avoid lemons with a dry or dull peel, as the zest provides much of the aroma of the dish.
Use the best lemons you can find. If available, Sorrento lemons or Sfusato Amalfitano are ideal because of their intensely fragrant peel. Eureka and Lisbon lemons are also excellent alternatives and are widely available outside Italy.
Prefer long pasta. Spaghetti are perfect for this sauce because the lemon emulsion coats the long strands evenly. Linguine, tagliolini, fettuccine, or tagliatelle also work well. If you want to make the pasta from scratch, you can use our homemade pasta recipe. Dry durum wheat pasta is particularly suitable because it holds its texture during the final cooking in the pan.
Keep the heat under control. Cook the lemon sauce gently so the zest and garlic don't burn. Once you add the pasta, use medium heat and toss frequently to help the sauce emulsify without reducing too quickly.
Add pasta water gradually. The starchy cooking water is essential for creating the creamy texture of Spaghetti al Limone. Add it one ladleful at a time, allowing the pasta to absorb the liquid before adding more.
Why Cook Spaghetti Risotto-Style?
In Italian, risottare la pasta means finishing the pasta directly in the pan with its sauce, much like cooking a risotto.
This technique is especially important for Spaghetti al Limone. As the pasta finishes cooking in the pan, it releases starch into the lemon, butter, and olive oil mixture. The starch helps emulsify the sauce, creating a smooth, glossy texture that coats the spaghetti naturally, without the need for heavy cream.
Variations and Substitutions
The classic version of Spaghetti al Limone is delicious in its simplicity, but you can easily adapt it with a few additional ingredients. Here are some variations to try.
Lemon Pepper Spaghetti. Toward the end of cooking, add about 3 tablespoons of grated Pecorino Romano or Parmigiano Reggiano and plenty of freshly ground black pepper. Toss well with the pasta water until creamy. The result is reminiscent of Cacio e Pepe, but with a fresh lemon aroma.
Lemon Spaghetti with Shrimp. Add peeled raw shrimp to the skillet during the last few minutes of cooking. Lemon and shrimp pair especially well, making this variation perfect for a more elegant dinner or a seafood meal.
Creamy Lemon Spaghetti with Heavy Cream. The traditional-style version doesn't need cream, but you can add about 120 ml (½ cup) heavy cream if you prefer a richer, more indulgent sauce. Add it to the skillet before the pasta and warm it gently with the lemon sauce.
Spaghetti al Limone Without Butter. For a dairy-free version, omit the butter and use a little more extra virgin olive oil instead. Finish the pasta with a drizzle of good-quality olive oil just before serving.
Try Different Herbs. Parsley is a classic choice, but mint and thyme also pair beautifully with lemon. You can omit the garlic for a more delicate flavor or add a pinch of red chili flakes for a slightly spicy version.
How to Serve Spaghetti al Limone
Spaghetti al Limone are best served immediately, while the sauce is still silky and creamy. Finish each plate with a little fresh lemon zest, chopped parsley, and, if you like, freshly ground black pepper.
Because of their fresh and delicate flavor, they pair especially well with light vegetable side dishes or simple Italian salads. For a summer meal, you can serve them with Fennel and Orange Salad or a fresh Caprese Salad.
For a more complete menu, Spaghetti al Limone also work beautifully before a simple fish or seafood main course.
Storage
Spaghetti al Limone are best enjoyed immediately, while the sauce is still silky and creamy. As the pasta cools, the sauce thickens and loses the delicate emulsion created with the starchy cooking water.
If you have leftovers, you can store them in an airtight container in the refrigerator for up to 1 day, but the texture will not be as good as when freshly made.
Freezing is not recommended, as the sauce can separate and the pasta may become soft after thawing.
