Lemon Spaghetti Recipe: 20-Minute Italian Pasta Favorite 2026

Lemon spaghetti is one of those Italian pasta dishes that proves how far a few humble ingredients can go. Garlic softened in butter, the zest and juice of a fresh lemon, and a handful of grated Parmesan come together into a silky, fragrant sauce that coats every strand.

The whole thing takes about 20 minutes from start to finish, and most of that time the pasta is simply boiling away while you make the sauce in a skillet. It is a perfect quick lunch or a light dinner for one, and the fresh, natural lemon flavor keeps it tasting bright rather than heavy.

Ingredients for Lemon Spaghetti

These amounts make one generous single serving of lemon spaghetti.

• 100 g spaghetti
• Salt
• 1 tablespoon butter
• 1 garlic clove
• 1 lemon (juice and zest)
• 30 g Parmesan cheese
• A few leaves of fresh basil

How to Make Lemon Spaghetti Step by Step

1. Boil the spaghetti

In a pot, boil 100 g of spaghetti in plenty of salted water for the time indicated by the manufacturer on the package. Keep the cooking water handy before draining, since a little of that starchy liquid is what helps the sauce come together later.

2. Sauté the garlic in butter

Meanwhile, prepare the lemon sauce in a skillet. Heat 1 tablespoon of butter and sauté 1 chopped garlic clove in it for 1 minute, just until it smells fragrant and sweet without browning.

3. Add the lemon zest

Add the zest of 1 lemon, lower the heat, and keep the skillet over low heat. The zest releases its citrus oils into the warm butter, which is where most of the lemon aroma comes from.

4. Toss the pasta with the cooking water and lemon juice

Transfer the drained pasta to the skillet along with half a glass of the cooking water and mix well. Then add the lemon juice, tossing so the starchy water and butter emulsify into a light, glossy coating.

5. Add the Parmesan and basil

Remove the skillet from the heat and add 30 g of grated Parmesan cheese and a few chopped basil leaves. Stir until the cheese melts into the sauce, giving it that creamy texture without any cream at all.

6. Season and serve right away

Season with salt and pepper to taste and serve this delicious lemon pasta dish immediately so you can enjoy it freshly made, while the sauce is still loose and silky.

Tips for the Best Lemon Spaghetti

Use the starchy cooking water

The creaminess of the lemon sauce in this recipe comes from the grated Parmesan melting with part of the cooking water, which has enough starch to create a smooth, flavorful sauce. Save a little before you drain the pasta, and add it gradually so the sauce never turns watery.

Keep the heat low with the zest

Once the lemon zest goes in, drop the heat to low and keep the skillet there. High heat can turn the garlic bitter and dull the fresh citrus notes you are after.

Finish with fresh basil

To serve these lemon spaghetti, you can add a few basil leaves to garnish just before serving, which gives an irresistible finishing touch. Tear them rather than chop them finely so they stay green and fragrant.

30 Home-Cooked Recipes I Keep Coming Back To

If you're anything like me, your kitchen rotation probably includes a little bit of everything — cozy comfort plates, tried-and-true dishes from around the globe, and sweets that make a crowd happy.

When a rich, indulgent treat is calling my name, I reach for this La Viña Molten Cheesecake recipe, this refined Original French Crème Brûlée recipe, or a luxurious Chocolate Mousse Cake recipe. And on days when only something fruity and soothing will do, this timeless French Tarte Tatin recipe is my go-to.

Mornings and lighter plates call for these airy Oatmeal and Banana Pancakes recipe, a hearty Stuffed Sweet Potato recipe, or these bright Eggs Stuffed with Avocado and Salmon recipe. And for a gluten-free staple I can keep on hand, this no-fuss Gluten-Free Rice Flour recipe does the trick.

Tapas and Mediterranean flavors are a constant craving, so I switch between this punchy Basque Tuna with Tomato recipe, golden Patatas Bravas Air Fryer recipe, silky Tirokafteri Greek Dip Sauce recipe, and a cool Burrata Salad with Tomato and Pesto recipe. And when the occasion begs for something a touch fancier, this elegant Italian Vitello Tonnato recipe is what I serve.

Come lunch or dinnertime, these are the dishes I hand out to friends most often: a soul-warming Meatballs in Spanish Sauce recipe, a time-honored Meatballs in Almond Sauce recipe, a deeply savory Italian Bolognese Sauce recipe, and velvety Chicken Croquettes in Thermomix recipe. For something more substantial, out comes this oven-baked Greek Pastitsio Pie recipe, a homey Potatoes and Squid Stew recipe, or the deeply comforting French Boeuf Bourguignon recipe.

Street-food cravings and party spreads usually mean this succulent Homemade Chicken Doner Kebab recipe, crispy Salchipapas recipe, boldly seasoned Mexican Pork Carnitas recipe, or these crisp Korean Hobak Jeon recipe.

Even More Tasty Recipes to Cook for the Family

After years of cooking, testing, and tweaking in my own kitchen, I've come to believe the greatest dishes are built on three things: simplicity, techniques you can trust, and flavor that really pops.

Every recipe gathered here is one I genuinely cook over and over — whether it's a fast solo meal or a spread I'm putting together for the people I love.

On the sweet side, the rich, silky Orange Chocolate Mousse Recipe is a favorite of mine when I want something that feels fancy yet comes together without fuss. Another dessert I adore is the caramelized Trdelnik Slavic Pastry Recipe, modeled after the celebrated Central European chimney cake. If baking is your thing, knowing how to make syrup for better dessert texture pays off, and my Inverted Sugar Recipe walks through exactly how I do it at home.

When something light and unfussy sounds right, I tend to go with the timeless Italian Caprese Salad Recipe or a flawlessly cooked Simple Poached Egg Recipe. And for cozier, heartier fare, I'm quick to suggest the filling Meatball Sandwich Recipe, the velvety Russian Stroganoff Beef Recipe, and the fast weeknight winner One Pot Pasta Recipe.

Sharing dishes from across the globe is another joy of mine — among them the genuine Sorropotún de Bonito Fish Stew Recipe, golden Chilean Pumpkin Sopaipillas Recipe, and the traditional Spanish Cochifrito Segovian Fried Pig Recipe.

Air fryer cooking is another category I turn to often, since it delivers great texture while saving time. The ones I make most are Air Fryer Pork Ribs Recipe, Air Fryer Chicken Thighs Recipe, Air Fryer Sweet Potatoes Recipe, Air Fryer Baked Potatoes Recipe, Air Fryer Peppers Recipe, Air Fryer Mixed Sandwich Recipe, Air Fryer Toasted Bread Recipe, and Air Fryer Hard-Boiled Eggs Recipe.

And for anyone steering clear of wheat, my cozy Gluten-Free Lasagna Recipe shows that a classic baked pasta can still be rich, cheesy, and completely gratifying without any gluten.
