Takeaway
Lemon Parmesan pasta is a weeknight hero. It takes 20 minutes, uses pantry staples, and delivers a restaurant-quality sauce without cream.

Master this method, and you'll have a go-to dinner that feels special any night of the week.
Frequently Asked Questions
Can I use a different type of pasta?
Yes. Long pasta like spaghetti, linguine, or fettuccine works best because the sauce clings to the strands. Short pasta like penne or fusilli also work, but you may need to adjust the sauce amount slightly.
Why did my sauce turn clumpy or stringy?
This usually happens if the heat is too high when you add the cheese, or if you add all the cheese at once. Keep the heat on low or medium-low, add the Parmesan in small handfuls, and toss vigorously between additions. Using pre-shredded cheese (which contains anti-caking agents) can also cause clumping—always grate your own from a block.
Can I make this dairy-free?
Yes. Replace the butter with a good olive oil and use a high-quality vegan Parmesan that melts well. The sauce will be slightly thinner but still flavorful. Add an extra tablespoon of lemon juice to brighten it up.
How do I keep the pasta from getting sticky after draining?
Do not rinse the pasta after draining. The starch on the surface helps the sauce cling. Also, toss the pasta immediately with the sauce. If you need to hold it for a minute, toss it with a drizzle of olive oil.
Recipe: Lemon Parmesan Pasta
Equipment
- Large pot
- colander
- large skillet or sauté pan
- microplane or zester
- chef's knife
- cutting board
- wooden spoon
- measuring cups and spoons
Ingredients
- 12 ounces dried spaghetti or linguine
- 2 tablespoons unsalted butter
- 3 cloves garlic (thinly sliced)
- 1 teaspoon lemon zest (from 1 large lemon)
- 1/4 cup fresh lemon juice (from 1-2 lemons)
- 1 cup finely grated Parmesan cheese (plus more for serving)
- 1/2 teaspoon kosher salt (plus more for pasta water)
- 1/4 teaspoon freshly ground black pepper
- 1/4 cup chopped fresh parsley (optional, for garnish)
Instructions
- Bring a large pot of salted water to a rolling boil (about 1 tablespoon salt per 4 quarts water). Add the pasta and cook until al dente, about 1 minute less than package directions. Reserve 1 1/2 cups pasta water before draining. Drain pasta, but do not rinse.
- While the pasta cooks, melt the butter in a large skillet over medium heat. Add the sliced garlic and cook, stirring frequently, until fragrant and just golden, about 1 minute. Do not let it brown.
- Reduce heat to low. Add the lemon zest and lemon juice to the skillet. Stir for 30 seconds.
- Add 1/2 cup of the reserved pasta water to the skillet. Increase heat to medium-low and bring to a gentle simmer.
- Add the drained pasta to the skillet. Toss with tongs to coat. Sprinkle the Parmesan cheese over the pasta in three additions, tossing well after each addition. Add more pasta water, 1/4 cup at a time, until the sauce is creamy and coats each strand. The sauce will look thin at first but will thicken as the cheese melts and emulsifies.
- Season with salt and pepper. Taste and adjust lemon or salt as needed.
- Serve immediately in warm bowls. Top with extra Parmesan and parsley if using. The pasta will thicken as it cools, so serve right away.
