Lemon Garlic Spaghetti

Lemon garlic spaghetti is a bright, simple pasta where a silky sauce of garlic, lemon juice, and pasta water clings to every strand. The key is finishing the pasta in the sauce so it absorbs the flavor instead of sitting in plain olive oil.

Ingredients for Lemon Garlic Spaghetti

Spaghetti is the base and soaks up the lemon and garlic flavors. Garlic becomes soft and sweet when cooked gently in olive oil, giving the sauce its backbone. Lemon juice and lemon zest provide brightness and acid that balance the richness of the oil. Olive oil emulsifies with the starchy pasta water to create a silky coating. Salt seasons the pasta water and the finished dish. Black pepper adds a gentle heat, and fresh parsley brings color and a fresh finish. Parmesan cheese adds umami and helps thicken the sauce.

Why This Lemon Garlic Spaghetti Works

The pasta cooks until just short of tender, then finishes in the sauce with a splash of starchy cooking water. This starch acts like glue, letting the oil, lemon juice, and cheese come together into a creamy sauce that coats the pasta instead of sliding off.

The garlic is cooked slowly in olive oil over low heat so it turns golden and mellow instead of harsh and bitter. Lemon juice and zest go in at the end to stay bright and fresh. The result feels rich but tastes light.

Mistakes To Avoid

Draining the pasta and rinsing it washes away the starch that makes the sauce cling. Skip the rinse and go straight from the colander to the pan with the garlic and oil.

Using too little pasta water leaves the sauce gluey and thick instead of silky and light. Start with 1/2 cup and add more a few tablespoons at a time until the sauce flows and coats the pasta.

Cooking the garlic over medium or high heat turns it brown and bitter instead of golden and sweet. Keep the heat low and stir often so it softens without browning.

Letting the finished pasta sit in the warm pan causes it to continue absorbing water and turn mushy. Plate it right away and serve it hot so the texture stays tender but not soft.

Ingredients

• 1 pound spaghetti
• 6 cloves garlic, thinly sliced
• 1/2 cup olive oil
• Juice of 2 large lemons, about 1/3 cup
• Zest of 1 lemon, about 2 teaspoons
• Salt to taste
• 1/2 teaspoon black pepper
• 1/4 cup fresh parsley, chopped
• 1/2 cup grated Parmesan cheese

Step-by-step Instructions

1. Bring a large pot of salted water to a boil over high heat. The water should taste like sea water.
2. Add the spaghetti and cook for one minute less than the package directions, stirring once. It should bend but still feel firm when bitten.
3. Reserve 1 cup of the starchy cooking water in a liquid measuring cup, then drain the pasta into a colander.
4. While the pasta cooks, pour the olive oil into a large skillet. Add the sliced garlic and place over low heat.
5. Cook the garlic gently for 3 to 5 minutes, stirring often, until it turns light golden and smells sweet. Do not let it brown.
6. Add the cooked pasta to the skillet with the garlic oil. Toss gently to coat.
7. Pour in 1/2 cup of the reserved pasta water. Toss constantly for 1 to 2 minutes over low heat until the water is absorbed and the pasta glistens.
8. Add the lemon juice and lemon zest. Toss well. If the sauce seems too thick, add more pasta water a tablespoon at a time until it flows.
9. Remove from heat. Add the black pepper, Parmesan cheese, and fresh parsley. Toss gently one more time.
10. Divide among four bowls and serve hot right away.
