Fresh basil is a fragrant herb that brings vibrant, peppery flavor to countless dishes, but perhaps nowhere does it shine more than in a classic pesto pasta. This recipe highlights basil’s freshness, pairing it with garlic, pine nuts, Parmesan, and olive oil to create a sauce that’s both simple and deeply satisfying. Whether you’re looking for a quick weeknight meal or a way to use up a garden bounty, this pesto pasta is a reliable favorite.
Ingredients
- 2 cups fresh basil leaves, packed
- 1/2 cup extra-virgin olive oil
- 1/3 cup pine nuts (or walnuts as a substitute)
- 2–3 garlic cloves, peeled
- 1/2 cup freshly grated Parmesan cheese
- 1/4 teaspoon kosher salt, plus more to taste
- 1/4 teaspoon freshly ground black pepper
- 12 ounces dried pasta (spaghetti, linguine, or penne work well)
- 2 tablespoons reserved pasta cooking water
- Optional: 1/2 teaspoon lemon zest and 1 tablespoon lemon juice
Instructions
- Prepare the basil and other ingredients: Wash the basil leaves and gently pat them dry with a clean towel. Peel the garlic cloves and grate the Parmesan cheese if not pre-grated.
- Toast the pine nuts: In a small, dry skillet over medium-low heat, toast the pine nuts, stirring frequently, until golden and fragrant (about 3–4 minutes). Remove from the pan immediately to prevent burning and let cool.
- Make the pesto: In a food processor or high-powered blender, combine basil leaves, toasted pine nuts, garlic, Parmesan, salt, and pepper. Pulse several times until finely chopped.
- Add oil: With the machine running, slowly drizzle in the olive oil and blend until the mixture becomes a thick, smooth sauce. Scrape down the sides as needed. Taste and adjust seasoning, adding the lemon zest and juice if you like a brighter flavor.
- Cook the pasta: Bring a large pot of salted water to a boil. Add the pasta and cook according to package instructions until al dente. Reserve 1/2 cup pasta water, then drain pasta.
- Toss pasta with pesto: Return drained pasta to the pot. Add 1/2 cup of pesto and 2 tablespoons of reserved pasta water. Toss to coat, adding more pesto or pasta water as needed for a silky sauce that clings to the noodles.
- Serve: Divide pasta among bowls. Top with extra Parmesan, a sprinkle of black pepper, and a few torn basil leaves for garnish. Serve immediately.
Tips
- Substitutions: If you don’t have pine nuts, walnuts or almonds make good substitutes. For a dairy-free version, use nutritional yeast instead of Parmesan.
- Blanching basil: For an even brighter green pesto, quickly blanch basil leaves in boiling water for 10 seconds, then plunge into ice water before processing.
- Prevent bitterness: Use a gentle touch with the food processor and avoid over-blending, which can make basil taste bitter.
- Make ahead: Pesto can be made up to 3 days ahead and stored in an airtight container in the refrigerator with a thin layer of olive oil on top.
Serving Suggestions
- Serve pesto pasta as a main dish with a crisp green salad and crusty bread.
- Top with grilled chicken, shrimp, or roasted vegetables for added protein.
- Use pesto as a spread for sandwiches or as a drizzle over grilled fish.
- Pair with a light white wine such as Pinot Grigio or Sauvignon Blanc for a refreshing meal.
Variations
- Pesto Rosso: Add sun-dried tomatoes for a deeper, slightly sweet flavor.
- Spicy Pesto: Blend in a pinch of red pepper flakes or a fresh chili for heat.
- Vegan Pesto: Use nutritional yeast instead of Parmesan and add a tablespoon of miso for umami.
- Nut-Free Pesto: Omit the nuts or use sunflower seeds for a safe alternative.
Storage and Reheating
Refrigerator: Store leftover pesto pasta in an airtight container for up to 3 days. The pesto itself (without pasta) can be refrigerated for 3–4 days, covered with a thin layer of olive oil to prevent browning.
Freezer: Pesto freezes well. Spoon into ice cube trays or small containers, cover with oil, and freeze for up to 3 months. Thaw in the refrigerator overnight before using.
Reheating: To reheat pasta, add a splash of water and warm gently in a skillet over low heat, stirring frequently. Avoid microwaving for too long, as basil can lose its bright color and flavor.
Frequently Asked Questions
- Can I use other herbs instead of basil?
- Yes, you can substitute part or all of the basil with other fresh herbs such as parsley, cilantro, or arugula. Each will impart a different character to the pesto, though classic pesto relies on basil for its signature flavor.
- Do I need a food processor to make pesto?
- No, you can use a high-powered blender, or even a mortar and pestle for a more traditional, rustic texture. A mortar and pestle will take more time but is gentler on the basil and can enhance flavor.
- How can I prevent my pesto from turning brown?
- Basil oxidizes quickly. To keep pesto green, use fresh leaves, work quickly, and cover the finished sauce with a thin layer of olive oil before storing. Blanching basil before blending also helps preserve color.
- Is it safe to eat raw basil?
- Yes, fresh basil is safe and commonly eaten raw in salads, pesto, and garnishes. Always wash basil thoroughly before use to remove dirt or potential contaminants.
- Can I make this recipe gluten-free?
- Absolutely. Simply substitute your favorite gluten-free pasta. The pesto itself is naturally gluten-free, so just check your pasta package for allergy information.
- What should I do if my pesto is too thick or too thin?
- If the pesto is too thick, add a bit more olive oil or pasta water, a tablespoon at a time, until you reach the desired consistency. If it’s too thin, blend in more basil, cheese, or nuts to thicken.
