The Essential Ingredients for The Best Pesto
The simplicity of this dish means that the quality of your fresh ingredients is absolutely paramount.
For the Perfect Homemade Basil Pesto:
- Fresh Basil: The heart and soul of the sauce! You will need a large, 2-cup bunch of fresh, vibrant green basil leaves.
- Toasted Pine Nuts: Toasting your pine nuts in a dry skillet for a few minutes before you blend them is the secret that unlocks their deep, buttery, and nutty flavor.
- The Cheeses: A classic, authentic combination of salty, sharp Parmigiano-Reggiano and/or Pecorino Romano cheese is essential. It is crucial to grate your own cheese from a block for the best flavor and texture.
- Fresh Garlic: A few cloves of fresh garlic add a wonderful, pungent kick.
- Extra-Virgin Olive Oil: Because the oil is a primary ingredient, it is essential to use a high-quality, fruity, and flavorful extra-virgin olive oil.
- Fresh Lemon Juice: A squeeze of fresh lemon juice is a brilliant secret ingredient that not only brightens the flavor of the pesto but also helps to keep it a beautiful, vibrant green color.
For the Pasta:
- Spaghetti or Bucatini: A long, classic pasta shape is the perfect vehicle for this light, silky sauce.
- Starchy Pasta Water (The “Liquid Gold”!): This is the most important secret ingredient for a perfect sauce!
Step-by-Step to the Best Pesto Pasta
This elegant meal comes together in the time it takes to boil your pasta.
Part 1: How to Make the Perfect Homemade Basil Pesto
Step 1: In a food processor or a blender, combine the 2 cups of fresh basil leaves, the 1/3 cup of toasted pine nuts, the 2 minced garlic cloves, and the 1/2 cup of grated Parmesan or Pecorino cheese.
Step 2: Pulse the mixture a few times until the ingredients are finely chopped.
Step 3: With the food processor running on low, slowly stream in the 1/3 cup of extra-virgin olive oil until the mixture is well combined.
Pro Tip (The Secret to Bright Green Pesto!): To keep your pesto from browning, you can quickly blanch your basil leaves in boiling water for 15 seconds and then immediately plunge them into an ice bath before you blend them. The addition of a little lemon juice also helps!
Part 2: Cook the Pasta (and Save That Water!)
Bring a large pot of heavily salted water to a rolling boil. Add your 12 ounces of spaghetti and cook according to the package directions until it is perfectly al dente (tender but still has a firm bite).
Crucial Pro Tip: Just before you drain the pasta, be sure to reserve at least 1 cup of the starchy, salty pasta water. This is the most important ingredient for your sauce! Drain the cooked pasta.
Part 3: Create the Creamy Pesto Sauce
Step 1: Transfer your hot, drained pasta to a large skillet or back into the warm pot, off the heat.
Step 2: Add your prepared homemade pesto and about 1/2 cup of your reserved, hot starchy pasta water to the pasta.
Step 3 (The Magic Step!): Toss everything together vigorously with a pair of tongs. The starchy water will combine with the pesto and the heat from the pasta to create a beautiful, light, and surprisingly creamy sauce that clings to every noodle. If the sauce seems too thick, you can add another splash of the pasta water until it has reached your desired, silky consistency.
Give the dish a final taste and season with any more salt and pepper if needed. Serve the hot pesto pasta immediately in warm, shallow bowls, with an extra sprinkle of grated Parmesan cheese and some fresh basil leaves.

- This is a very fast meal, perfect for a busy weeknight.
Storage and Make-Ahead Tips
A fresh pesto pasta is at its absolute peak of perfection in the moments right after it is made.
- Make-Ahead: The homemade basil pesto is the perfect make-ahead component! You can prepare the pesto and store it in an airtight container or a jar in the refrigerator for up to 1 week. For the best, most vibrant green color, you can pour a thin layer of olive oil directly on the surface of the pesto before you cover it.
- Storage: Store any leftover pasta in an airtight container in the refrigerator for up to 4 days.
- Freezing Pesto: Pesto freezes beautifully! You can freeze it in small jars, or you can portion it into an ice cube tray and freeze it into perfect, individual serving-sized cubes.

Creative Recipe Variations
- Add a Savory Protein: For a hearty, non-vegetarian version, this pasta is absolutely fantastic when tossed with some sliced, grilled chicken, some sautéed shrimp, or some crispy, crumbled pancetta. For a vegetarian protein boost, you can stir in one 15-ounce can of drained and rinsed cannellini beans or chickpeas.
- Add Some Fresh Vegetables: For a pop of color and some extra texture, you can stir in about 1 cup of halved cherry tomatoes or some steamed and chopped asparagus or green beans at the very end.
- Use a Different Nut or Herb: If you don’t have pine nuts, you can make a delicious pesto with toasted walnuts, almonds, or even pistachios. You can also substitute about half of the basil with fresh baby arugula or parsley for a different, peppery flavor profile.

Frequently Asked Questions (FAQs)
Q1: What is the absolute, number one secret to a creamy pesto sauce that isn’t just an oily mess?
The secret is the starchy pasta water! This cloudy, salty water that your pasta has cooked in is full of wonderful, dissolved starches. This starchy water, often called “liquid gold” by Italian chefs, is the perfect, natural emulsifier. When you add a generous splash of it to your thick pesto paste and toss it vigorously with the hot pasta, it helps to transform the oil-based pesto into an incredibly creamy, luscious, and glossy sauce that clings perfectly to every single noodle.
Q2: What is the secret to keeping my homemade pesto a beautiful, bright green color and preventing it from turning brown?
The browning of pesto is a natural process called oxidation. A quick and easy trick to slow this down is to add a squeeze of fresh lemon juice to your pesto, as the acid helps to preserve the color. For an even more foolproof, vibrant green, you can blanch your basil leaves in boiling water for just 15 seconds and then immediately shock them in an ice bath before you blend them.
Q3: Can I make homemade pesto without a food processor?
Yes! The most traditional and authentic way to make pesto is with a mortar and pestle. This method actually creates a superior texture, as it crushes the ingredients and releases their essential oils rather than simply chopping them. It just requires a bit more elbow grease!
Q4: Can I freeze homemade pesto?
Yes, pesto freezes beautifully! It is a fantastic way to preserve the fresh flavor of summer basil. You can freeze it in small, airtight containers or jars. A great trick is to portion the fresh pesto into an ice cube tray. Once the cubes are frozen solid, you can pop them out and store them in a freezer-safe, resealable bag for perfect, individual portions.
Q5: What is the difference between Pecorino cheese and Parmesan cheese?
While they are both hard, salty, Italian cheeses that are perfect for grating, Parmigiano-Reggiano is made from cow’s milk and has a nutty, slightly fruity flavor. Pecorino Romano, on the other hand, is made from sheep’s milk and is typically a bit saltier and tangier than Parmesan.
