15-Minute Lemon Garlic Butter Pasta

This is the back-pocket pasta every busy cook needs: hot spaghetti glossed with a silky lemon-garlic butter sauce, a snowfall of parmesan, and a pinch of heat. It tastes like a restaurant date night but comes together faster than takeout. If you like quick creamy pastas, you will also love our creamy cabbage alfredo.

🧺Ingredients

  • 12 oz spaghetti or linguine
  • 6 tbsp unsalted butter
  • 5 cloves garlic, thinly sliced
  • 1 tsp red pepper flakes
  • Zest and juice of 2 large lemons
  • 3/4 cup grated parmesan cheese, plus more to serve
  • 1/2 cup reserved pasta water
  • 1/2 tsp kosher salt, plus more for pasta water
  • 1/2 tsp black pepper
  • 1/4 cup chopped fresh parsley

👩‍🍳Instructions

  1. Boil the pasta. Bring a large pot of heavily salted water to a rolling boil. Cook the spaghetti 1 minute less than the package directions. Before draining, scoop out 1/2 cup of the starchy pasta water — this is what makes the sauce silky.
  2. Bloom the garlic. Meanwhile, melt the butter in a large deep skillet over medium heat. Add the sliced garlic and red pepper flakes; cook 60-90 seconds until fragrant and just golden. Do not let the garlic brown.
  3. Build the sauce. Stir in the lemon zest, lemon juice, salt, and pepper. Add 1/3 cup of the pasta water and swirl until the butter turns into a glossy, emulsified sauce.
  4. Toss and finish. Add the drained pasta straight to the skillet. Toss vigorously for 1 minute, showering in the parmesan a handful at a time and splashing in more pasta water until every strand is coated and shiny. Shower with parsley and extra parmesan, and serve immediately.

🍋 Sauce smarts

Pasta water is liquid gold here — the starch is what turns butter and lemon juice into a real sauce instead of an oily slick. Toss off the heat if the sauce looks like it might split; a splash of cold pasta water brings it right back together. Add a handful of baby spinach or some seared shrimp to make it a full meal.

❓ Common questions

Can I use bottled lemon juice?
Fresh lemons make all the difference here since zest is half the flavor, but bottled juice works in a pinch — use 3 tablespoons and skip the zest.

What pasta shape works best?
Long strands like spaghetti, linguine, or fettuccine grab the buttery sauce best, but short shapes like penne work too.

How do I keep the sauce from breaking?
Keep the heat at medium (never high) and toss off the heat if needed. The starchy pasta water is the emulsifier — don't skip it.
