Fresh basil leaves are the heart of many Italian dishes, and nothing showcases their vibrant flavor more than classic homemade basil pesto. This recipe captures the herb’s aromatic, peppery notes in a creamy, garlicky sauce that comes together in minutes. Whether tossed with pasta, spread on sandwiches, or used as a dip, this basil pesto delivers a burst of summer freshness any time of year.
Ingredients
- 2 cups fresh basil leaves, packed (about 60g)
- 1/2 cup freshly grated Parmesan cheese (about 45g)
- 1/3 cup pine nuts (about 40g)
- 2 garlic cloves, peeled
- 1/2 cup extra-virgin olive oil (120ml)
- 1/2 teaspoon fine sea salt, plus more to taste
- 1/4 teaspoon freshly ground black pepper
- 1 teaspoon freshly squeezed lemon juice (optional, for brightness)
Instructions
- Prepare the basil: Rinse the basil leaves under cold water and gently pat dry with paper towels or a salad spinner. Remove any thick stems.
- Toast the pine nuts: Place pine nuts in a dry skillet over medium-low heat. Stir frequently for 2–3 minutes until lightly golden and fragrant. Immediately transfer to a plate to cool. (Watch closely to prevent burning.)
- Blend the dry ingredients: In a food processor or blender, combine basil leaves, toasted pine nuts, garlic cloves, Parmesan, salt, and black pepper. Pulse several times until finely chopped and well combined.
- Stream in the olive oil: With the processor running, slowly drizzle in the olive oil. Scrape down the sides as needed. Process until the mixture is smooth but still has some texture. Avoid over-processing, which can make the pesto dense.
- Finish and adjust seasoning: Add lemon juice if using. Taste and season with additional salt, pepper, or lemon as desired. If the pesto seems too thick, add a splash more olive oil.
- Serve or store: Use immediately, or transfer to a clean jar and cover with a thin layer of olive oil to prevent browning. Refrigerate until ready to use.
Tips
- Substitutions: If pine nuts are unavailable or expensive, try walnuts, almonds, or cashews. For a nut-free pesto, use sunflower seeds or pepitas.
- Cheese choices: Parmigiano-Reggiano is traditional, but Pecorino Romano or Grana Padano also work well. For a dairy-free version, substitute nutritional yeast and a pinch more salt.
- Keep it green: To prevent pesto from turning brown, always use very fresh basil, and cover the finished sauce with a thin layer of olive oil before storing.
- Texture control: For a chunkier pesto, pulse ingredients briefly. For a smoother sauce, process a little longer, but avoid overheating, which dulls the basil’s flavor.
Serving Suggestions
- Pasta: Toss with hot cooked pasta and a splash of reserved pasta water for a silky sauce.
- Sandwich spread: Spread on crusty bread, panini, or wraps for a burst of herby flavor.
- Pizza: Drizzle over freshly baked pizza as a finishing touch, or use instead of tomato sauce for a white pizza.
- Veggies and proteins: Dollop onto grilled vegetables, chicken, fish, or tofu.
- Dip: Serve alongside crudités or swirl into hummus or Greek yogurt for a vibrant dip.
Variations
- Spinach or arugula pesto: Replace half the basil with baby spinach or arugula for a milder or pepperier flavor.
- Sun-dried tomato pesto: Add 1/4 cup sun-dried tomatoes with the basil for a sweet-savory twist.
- Cilantro or parsley pesto: Swap some or all of the basil for fresh cilantro or flat-leaf parsley for a different herbal profile.
- Vegan pesto: Omit cheese entirely and add 2–3 tablespoons nutritional yeast for cheesiness.
- Spicy pesto: Add a pinch of red pepper flakes or a small fresh chili for heat.
Storage and Reheating
Homemade basil pesto is best fresh, but it stores well with proper care:
- Refrigerator: Store pesto in an airtight container, topped with a thin layer of olive oil to minimize oxidation. It keeps for up to 5 days in the fridge.
- Freezer: Portion pesto into ice cube trays or small containers and freeze for up to 3 months. Thaw overnight in the refrigerator before use.
- Reheating: Pesto should not be boiled or microwaved at high heat, as this dulls its flavor and color. Instead, gently bring to room temperature or stir into hot pasta right before serving.
Frequently Asked Questions
- Can I make pesto without a food processor?
Yes! You can use a mortar and pestle for a more rustic texture, or finely chop all ingredients by hand and mix together. The mortar and pestle method is traditional and brings out basil’s aroma, though it takes more time. - Why does my pesto turn brown?
Basil oxidizes quickly when exposed to air, causing browning. To minimize this, use very fresh basil, process quickly, and cover the surface of stored pesto with olive oil. Adding a splash of lemon juice also helps preserve the color. - How can I make my pesto creamier?
For a creamier pesto, add an extra tablespoon or two of olive oil, or blend in a tablespoon of room-temperature unsalted butter at the end. Some cooks also add a spoonful of ricotta or cream cheese for extra richness. - Is it safe to eat raw garlic in pesto?
Yes, raw garlic is a classic ingredient in pesto and safe to eat. If you prefer a milder garlic flavor, use one clove instead of two, or briefly blanch the garlic in boiling water before blending. - Can I use dried basil?
Dried basil is not recommended for pesto, as it lacks the vibrant flavor and color of fresh basil. For best results, always use fresh leaves. If you have leftover fresh basil, freeze it for future pesto batches. - What pasta shapes work best with pesto?
Pesto clings well to shapes with grooves or twists, such as trofie, fusilli, penne, or farfalle. However, it also works beautifully with spaghetti or linguine. Reserve a splash of pasta water to help the sauce coat the noodles evenly.
