Ingredients You’ll Need

Since there are so few ingredients needed to make this fresh lemon spaghetti, quality is key. Check out some notes on what you’ll need below, and scroll down to the recipe card for a printable ingredients list.

  • Spaghetti – Or any pasta you’d like. Other good options are linguine and fettuccine. Or, channel your inner Nonna with homemade egg noodles.
  • Butter – You can use butter or olive oil. Butter has a richer flavor.
  • Garlic – Freshly minced. You can adapt the number of cloves to taste.
  • Crushed Red Pepper Flakes – For a hint of kick. Feel free to omit the red pepper flakes if you’re sensitive to spice.
  • Heavy Cream – Or whole milk.
  • Parmesan Cheese – Freshly grated parmesan cheese. Another hard, sharp cheese, like pecorino or Parmigiano also works. Reserve some of the grated cheese to use as a garnish, too.
  • Parsley – You can substitute fresh chopped parsley with another herb, like thyme or basil.
  • Lemons – You’ll need the zest and juice.
  • Salt and Pepper

How to Make Lemon Spaghetti

The beauty of this fresh lemon pasta is in how simple it is to make. Find printable instructions in the recipe card. For now, here’s a quick step-by-step! You’ll start by boiling spaghetti noodles on the stovetop, and while you’re doing that:

  • Make the sauce. Melt butter in a skillet, and add garlic and red pepper flakes. Let the garlic cook for a minute so that it’s fragrant. Then, pour in the heavy cream.
  • Add the pasta. Drain your cooked spaghetti and immediately toss it with the cream sauce.
  • Finish and serve. Lastly, stir in parmesan, parsley, lemon zest, and lemon juice. Season your lemon pasta to taste with salt and pepper, sprinkle over some extra parm, and serve. That’s it!

Tips for Success

These are my pro tips for the best possible pasta dish:

  • Use fresh lemon. This is a MUST for the best possible flavor when making lemon pasta. Also, zest the lemon before you squeeze it for the juice.
  • Freshly grate the cheese. Buy a wedge or block of parmesan and grate it fresh. The flavor and texture is a million times better!
  • Salt the pasta water. Add 2-3 spoonfuls of salt to the water you use to boil the spaghetti. Well-seasoned pasta water is key to flavorful pasta!
  • Make use of the pasta water. For an even saucier dish, transfer the cooked pasta directly from the pot of boiling water to the sauce, along with a ladleful of pasta water. The starches in the pasta water emulsify with the sauce, making it creamier.
  • Add breadcrumbs. Turn this lemon spaghetti into a variation of my creamy Caesar pasta with a sprinkling of garlicky toasted breadcrumbs.

What to Serve With Lemon Spaghetti

Zesty lemon spaghetti is the perfect side dish or light dinner, especially in warm weather months. Serve your creamy lemon pasta dinner outdoors, paired with a glass of Pinot Grigio and easy apps like bruschetta or Tuscan sausage dip with a rustic homemade baguette. For a heartier meal, add a protein, like grilled chicken or shrimp, and serve this spaghetti with a side of green salad or asparagus.

Storing and Reheating Leftovers

  • Fridge. Store any leftover lemon spaghetti in an airtight container in the refrigerator for up to 3 days. To reheat, add the pasta to a saucepan, sprinkle it with a bit of water, and warm it on the stovetop until heated through. You can also use the microwave.
  • Freeze. Due to the cream sauce, I don’t recommend freezing. Luckily, this recipe is quick to whip up fresh every time!

    Fast, easy, and gorgeous. Sign me up girl! I’m still wishing I had more zucchini in the garden though to make your chocolate cake. The best!

  2. As much as I love this dish, I equally love your white square plate! I am a huge fan of butter and I don’t even care what the first 4 letters of butter are! I will not let that discourage me! Ha. It just adds the right flavor to every meal!!!
