🧄 What Is Pesto?

Pesto is a traditional Italian sauce originating from Genoa in the Liguria region. The classic version, known as Pesto alla Genovese, is made with:

Fresh basil leaves
Garlic
Pine nuts
Parmesan cheese (or Pecorino)
Olive oil

The word “pesto” comes from the Italian verb pestare, meaning “to crush” or “to pound,” which reflects how it was traditionally made with a mortar and pestle.

Today, pesto is enjoyed all over the world and has many variations, but nothing beats the bright, aromatic flavor of the original.

🍝 Ingredients You’ll Need

Here’s what you’ll need to make this simple yet delicious pesto pasta recipe:

For the Pesto Sauce:

2 cups fresh basil leaves (packed)
2 cloves garlic
¼ cup pine nuts (or walnuts for a budget-friendly option)
½ cup grated Parmesan cheese
½ cup extra-virgin olive oil
Salt to taste
Optional: a squeeze of lemon juice for brightness

For the Pasta:

12 oz spaghetti, linguine, penne, or fusilli
Salt for pasta water
Optional toppings: cherry tomatoes, grilled chicken, roasted veggies, or extra cheese

👩‍🍳 How to Make Pesto Pasta (Step-by-Step)

Step 1: Cook the Pasta

Bring a large pot of salted water to a boil. Add your pasta and cook according to package instructions until al dente. Reserve ½ cup of the pasta water before draining.

Why salt the water? It’s the only chance to season the pasta from the inside out!

Step 2: Make the Pesto Sauce

While the pasta cooks, make the pesto.

Food processor method (quick & easy):

Add basil, garlic, and pine nuts to a food processor. Pulse until roughly chopped.
Add cheese and pulse again.
Slowly drizzle in the olive oil while blending until smooth.
Season with salt and a squeeze of lemon juice if desired.

Traditional mortar & pestle method:
If you’re feeling traditional, crush the garlic and salt together, add basil gradually, then nuts, cheese, and finally the oil. This method gives a more textured and aromatic result.

Step 3: Toss Pasta with Pesto

In a large bowl or the same pot (off the heat), combine the drained pasta and pesto sauce. Add a splash of the reserved pasta water to loosen the sauce and help it cling to the noodles.

Tip: Start with a few tablespoons of pesto and add more as needed. You can store extra in the fridge.

Step 4: Serve and Garnish

Serve immediately, garnished with extra Parmesan, cracked black pepper, and optional toppings like:

Sliced cherry tomatoes
Roasted pine nuts
Shredded rotisserie chicken
Sauteed shrimp
Steamed broccoli

🧂 Pro Tips for the Best Pesto Pasta

Use fresh basil. Avoid wilted or bitter leaves for the best flavor.
Toast your nuts. Lightly toasting pine nuts or walnuts enhances their flavor.
Don’t overcook pasta. Al dente texture helps the pasta hold up against the sauce.
Balance the flavor. Add lemon juice or extra cheese to adjust acidity and richness.
