Ingredients You’ll Need

Ingredients you’ll need for this recipe
  • 12 oz pasta (spaghetti, penne, or linguine)
  • ¾ cup basil pesto (store-bought or homemade)
  • 2 tbsp olive oil
  • 3 cloves garlic, minced
  • ½ cup reserved pasta water
  • ½ cup cherry tomatoes, halved (optional)
  • ¼ cup grated Parmesan cheese
  • Salt and black pepper, to taste
  • Fresh basil leaves, for garnish

Store-bought pesto works perfectly here. A good jarred pesto is totally fine. If you have homemade on hand, even better — use it generously.

Step-by-Step Guide

  1. Bring a large pot of salted water to a boil. Cook the pasta according to package directions until al dente. Before draining, reserve ½ cup of pasta water.
  2. Drain the pasta and set aside.
  3. Heat olive oil in a large skillet over medium heat. Add minced garlic and cook for 1 minute until fragrant. Don’t let it burn.
  4. Add the drained pasta to the skillet and toss to coat in the garlic oil.
  5. Add the pesto and pour in a splash of reserved pasta water. Toss until every piece of pasta is fully coated and the sauce is smooth and silky.
  6. Add cherry tomatoes if using and toss gently.
  7. Season with salt and black pepper. Top with grated Parmesan and fresh basil. Serve immediately.

Important Recipe Notes

  • Don’t skip the pasta water. The starch in it helps the pesto cling to the pasta evenly instead of clumping or sliding off.
  • Add pesto off the heat or over low heat. High heat turns basil pesto brown and kills the fresh flavor fast.
  • Be generous with the pesto. This dish is meant to be well-coated — don’t hold back on the sauce.
  • Cook pasta al dente. Slightly firm pasta holds up better when tossed and when reheated the next day.
  • Store leftovers in an airtight container in the fridge for up to 3 days. Add a splash of water when reheating to loosen the sauce.
  • Make it a full meal by adding grilled chicken, shrimp, or white beans for extra protein.
