Pesto with Jalapeno

Traditional pesto gets a jolt of green chile heat with this version. A seeded jalapeño goes into the food processor with pine nuts and garlic first, breaking down into a fiery base before the fresh basil and parsley get pulsed in with olive oil. Five minutes, no cooking, no cheese.

The parsley-basil blend is a smart call here. A full cup of parsley stretches the basil and adds a clean, peppery brightness that balances the jalapeño’s heat. All-basil pesto can taste heavy and one-note, but the parsley lightens the whole thing and gives it a greener, fresher color that lasts longer without oxidizing.

No Parmesan in this recipe, and that’s not an oversight. Leaving out the cheese makes this pesto vegan-friendly and lets the herb and pepper flavors stand front and center. It also means it freezes better, since cheese can turn grainy after thawing.

Kitchen Tips

• Process the nuts, garlic, and jalapeño first before adding the greens. The hard ingredients need more time to break down evenly.
• Pulse the herbs in short bursts rather than running the processor continuously. Over-processing heats the basil and turns it dark.
• Taste and adjust the heat. One small seeded jalapeño gives mild warmth. Leave the seeds in for serious spice.
• This pesto freezes well in ice cube trays. Pop out a cube whenever you need a burst of flavor for pasta, soup, or grilled meat.

Variations

• Serrano pesto: Swap the jalapeño for a serrano pepper for sharper, more intense heat.
• Walnut version: Use walnuts instead of pine nuts for a more affordable, earthier pesto.
• With Parmesan: Stir in freshly grated Parmesan after processing if you want a more traditional flavor with the added heat.
