Step-By-Step: How to Make Classic Pesto Pasta

  1. Boil the Pasta: Bring salted water to a rolling boil. Add pasta and cook until al dente. Reserve 1/4 cup of pasta water before draining.
  2. Sauté Onion: Heat olive oil in a skillet over medium heat. Add chopped onion and cook until soft and translucent.
  3. Add Pesto and Season: Stir in the pesto sauce, salt, and pepper. Warm through gently, taking care not to overcook the pesto.
  4. Combine: Toss the hot drained pasta with the pesto mixture and a splash of reserved pasta water for a silky sauce.
  5. Add Cheese: Stir in freshly grated Parmesan until the pasta is evenly coated and glossy.
  6. Serve: Plate immediately and finish with extra Parmesan, black pepper, or fresh basil leaves if desired.

Expert Tips for the Best Pesto Pasta

  • Don’t Overheat the Pesto: Direct high heat dulls the fresh basil flavor. Always warm it gently, just until heated.
  • Reserve Pasta Water: A splash of this starchy liquid makes your sauce extra creamy and helps it cling to the noodles.
  • Use Fresh Parmesan: Grated from a block, fresh cheese melts beautifully and tastes richer than pre-packaged shreds.
  • Go Green: Add spinach or arugula for extra nutrients and color.
  • Customize: Experiment with walnuts or almonds in your homemade pesto, or add a pinch of red pepper flakes for gentle heat.

Creative Variations and Additions

Make your pesto pasta uniquely yours with these mix-in ideas:

  • Proteins: Grilled chicken, sautéed shrimp, Italian sausage, or crispy chickpeas.
  • Veggies: Roasted cherry tomatoes, sautéed zucchini, bell peppers, or artichoke hearts.
  • Cheese: Try adding soft mozzarella pearls or crumbled goat cheese for extra creaminess.
  • Nuts: Toasted pine nuts or slivered almonds for crunch.
  • Sun-Dried Tomatoes: For a sweet, tangy pop.
