Rich and silky without heavy cream
Uses simple pantry ingredients

Perfect for busy weeknights or quick lunches

There was a tiny pasta place tucked between two narrow streets near the coast where the menu changed almost every evening depending on what was fresh that day. Some nights, the simplest pasta dishes ended up being the most memorable. A warm plate of spaghetti with garlic, olive oil, lemon, and plenty of grated cheese would arrive at the table glossy and fragrant, with the lemon cutting through the richness perfectly. This recipe always reminds me of those kinds of meals because it proves you do not need many ingredients to make something deeply satisfying, just like my Garlic Shrimp Gambas al Ajillo, and Spanish Sautéed Mushrooms with Garlic.

Now I make this lemon garlic spaghetti when I want dinner that feels comforting without being heavy. The butter and Parmesan create a silky sauce once mixed with the pasta water, while the lemon keeps everything fresh and balanced. I also love how quickly it comes together because most of the ingredients are already sitting in the kitchen. It is the kind of pasta that works just as well for a quiet weeknight dinner as it does for serving friends with Fresh Tomato Burrata Salad, Traditional Gazpacho, or warm bread on the side.

Key Ingredients in Lemon Garlic Spaghetti

You'll find the exact measurements in the recipe card, but here's a closer look at key ingredients and why I use them.

Spaghetti & Pasta Water: I like using spaghetti because it holds the lemon garlic sauce well without feeling too heavy. The pasta water helps bring the Parmesan, butter, and olive oil together into a silky sauce.
Garlic, Chili & Olive Oil: Extra virgin olive oil gives the sauce a smooth base, while fresh garlic adds the main flavor. I also add a little fresh red chili for gentle heat, but it should not overpower the lemon.
Lemon, Parsley & Seasoning: Lemon zest and fresh lemon juice make the pasta bright and fresh. Chopped parsley, salt, and black pepper keep the flavor balanced and simple.
Butter & Parmesan: I use unsalted butter and finely grated Parmesan to make the sauce glossy and rich without adding cream.

How to Make Lemon Garlic Spaghetti

You can find the complete printable recipe with measurements below, but for now, here's a quick overview of how it goes:

1. Cook the Spaghetti: Bring a large pot of salted water to a boil. Add the spaghetti and cook according to the package instructions until al dente. Before draining, reserve some of the pasta cooking water.

2. Prepare the Garlic and Lemon Base: While the pasta cooks, heat the olive oil in a large skillet. Add the finely chopped garlic and red chili, then cook over medium heat for 30-60 seconds until fragrant. Stir in the lemon zest and chopped parsley, and cook for 1-2 minutes.

3. Toss the Pasta: Transfer the cooked spaghetti directly into the skillet. Season with salt and pepper, then toss well. Add the butter, lemon juice, and a little reserved pasta water, and continue tossing until the spaghetti looks glossy and lightly coated.

4. Finish with Parmesan: Reduce the heat to low, add the Parmesan cheese, and toss until it melts into the sauce. Add a little more pasta water if needed to create a silky coating.

Tips for Silky Lemon Garlic Spaghetti

Add the Parmesan Slowly: I like adding the Parmesan little by little over low heat because it melts more evenly and keeps the sauce smooth.

Use Fresh Lemon Juice: The pasta, I find, tastes much fresher and brighter when made with freshly squeezed lemon juice instead of bottled.

Toss Until Glossy: I always give the spaghetti an extra minute in the pan so the sauce coats every strand properly and turns silky.

Storage

Store leftover lemon garlic spaghetti in an airtight container in the refrigerator for up to 3 days. I like reheating it gently with a splash of water to loosen the sauce and bring back the silk.

What to Serve With Lemon Garlic Spaghetti

This lemon garlic spaghetti pairs well with a simple tomato burrata salad, sautéed vegetables, or grilled chicken. If you want to keep the meal light, a slice of crusty ciabatta and a fresh green salad work beautifully alongside it.
