For 16 servings
- prep · ~3 min
Toast the Brazil nuts.
Place Brazil nuts in a dry pan over medium heat and toast for 2-3 minutes, shaking occasionally, until lightly golden and fragrant. Let cool completely.
TIPWatch the nuts closely — they burn fast and turn bitter. Remove from pan the moment they smell toasty. - prep · ~2 min
Prep the basil and garlic.
Wash basil leaves and pat them completely dry. Peel the garlic cloves.
- mix · ~1 min
Blend the nuts and aromatics first.
Add cooled Brazil nuts, garlic, and a pinch of salt to the food processor. Pulse until coarsely chopped — a few 1-second bursts are enough.
TIPProcess the nuts and garlic first so they break down uniformly before the soft leaves go in. - mix · ~1 min
Add basil and cheese.
Add basil leaves and grated Parmesan cheese to the food processor bowl. Pulse again, stopping to scrape down the sides, until a chunky paste forms.
TIPPulse, don't run the motor continuously — this keeps the pesto textured and prevents the basil from heating up and turning brown. - mix · ~1 min
Stream in the olive oil.
With the food processor running on low, slowly drizzle in olive oil through the feed tube until the pesto reaches a creamy, slightly coarse consistency.
- mix · ~1 min
Season to finish.
Transfer pesto to a bowl. Stir in the lemon juice and freshly ground black pepper. Taste and adjust salt if needed.
TIPAlways stir in lemon juice at the end — adding it during processing can dull the basil's bright green color. - serve
Use immediately or store.
Toss with hot pasta, spread on sandwiches, or dollop over grilled vegetables. For storage, transfer to a jar and float a thin layer of olive oil on top to prevent browning.
TIPPesto keeps 5 days in the fridge or freezes beautifully in ice-cube trays for single-serving portions.
What to keep in mind.
7 tips from the recipe — small details that make a real difference to the final dish.
- 1Toast the Brazil nuts just until fragrant and golden, then remove from the pan immediately to avoid bitterness.
- 2Pat basil leaves completely dry before blending – excess water makes the pesto watery and dulls its color.
- 3Pulse the nuts and garlic first so they break down evenly before adding the soft basil leaves.
- 4Pulse the basil and cheese in short bursts to keep the pesto textured and prevent the basil from heating up and turning brown.
- 5Stir in lemon juice at the end, not during blending, to preserve the basil's vibrant green color.
- 6Store pesto in a jar with a thin layer of olive oil on top to prevent browning; it keeps 5 days in the fridge.
- 7Freeze pesto in ice-cube trays for single-serving portions that are ready to toss into pasta or sauces.
Adapt it for your goals.
Vegan
Replace Parmesan cheese with 2 tablespoons of nutritional yeast for a dairy-free, umami-packed version that keeps the pesto creamy and cheesy-tasting.
Nut FreeNut-Free
Substitute Brazil nuts with sunflower seeds or pepitas (pumpkin seeds) for a nut-free pesto that still delivers a rich, toasty flavor and creamy texture.
SpicySpicy
Add 1 small red chili (seeded, if desired) to the food processor along with the garlic for a kick of heat that complements the herbaceous basil and buttery nuts.
High ProteinHigh-Protein
Swap half the basil with fresh spinach and add a handful of shelled hemp seeds for a protein boost (about 5g extra per serving) without sacrificing color or taste.

Frequently asked questions
Raw, unsalted Brazil nuts are best because toasting them yourself gives you control over doneness and salt level; pre-roasted or salted nuts can make the pesto too salty or bitter.
