Fresh Basil Pesto That's Ready in 5 Minutes and Stays Bright for Days
That first whiff when you walk into the kitchen—bright, garlicky, so green you can practically taste the summer—that's what this fresh basil pesto does. Blanched basil, good nuts, real Parmesan, and a food processor: five minutes, no fuss, and it won't turn brown on you by dinner. The only pesto recipe you'll need.
Equipment
- Small saucepan
- Bowl of ice water
- Fine-Mesh Strainer
- Food Processor
- Small skillet
- Rubber Spatula
Ingredients
- 3 cups packed fresh basil leaves
- 1/3 cup pine nuts or walnuts
- 2 cloves garlic
- 1/2 cup freshly grated Parmigiano-Reggiano
- 1/3 cup extra-virgin olive oil, plus more for covering
- 1 tablespoon fresh lemon juice
- 1/2 teaspoon flaky sea salt, plus more to taste
Instructions
- Blanch the basil: Bring a small pot of salted water to a boil. Have a bowl of ice water ready. Drop the basil leaves in and stir — 10 seconds, no more. They'll turn bright green immediately. Scoop them out with a slotted spoon or pour through a strainer, then plunge into the ice water. Drain well and squeeze out as much water as you can with your hands.
- Toast the nuts: In a dry small skillet over medium heat, toast the pine nuts or walnuts for 2–3 minutes, shaking the pan frequently, until they smell nutty and are lightly golden. Do not let them burn.
- In the food processor, pulse the garlic and cooled nuts until they're finely chopped — about 5–6 pulses.
- Add the blanched, squeezed basil and the grated Parmesan. Pulse again until everything is combined and the basil looks broken down.
- With the processor running, slowly pour the olive oil through the feed tube. Let it run until the pesto comes together into a thick, spreadable paste. Scrape down the sides once if needed.
- Add the lemon juice and ½ teaspoon salt. Pulse once or twice to combine. Taste on a piece of bread and add more salt if needed (remember the Parmesan is salty).
Notes
How to store: Transfer to an airtight jar, smooth the top, and drizzle with a thin layer of olive oil to seal. Refrigerate for up to 1 week. To freeze: spoon into ice cube trays (about 1 tablespoon each), freeze solid, then pop out and store in a zip-top bag for up to 3 months. Never microwave pesto – toss with hot pasta and a splash of pasta water instead.
Chef's tips: Do not over-process – you want texture, not a paste. Blanch every time, even if using immediately, to mellow astringency. Taste before adding extra salt – Parmesan is salty. Reserve pasta water to thin the pesto into a silky sauce.
Substitutions: For vegan, swap Parmesan for 2–3 tbsp nutritional yeast. For nut-free, use sunflower seeds or pepitas. For spicy, add ½ tsp red pepper flakes or a small jalapeño. Replace ¼ of the basil with parsley, mint, or arugula for a different flavor. Add lemon zest for extra brightness.
