ingredients needed for the recipe: basil, parmesan cheese, lemon, olive oil, salt, pepper, garlic and pepitas

Ingredients

Basil: Fresh basil is the star—use tender leaves for the best herbaceous flavor.

Pepitas: Hulled pumpkin seeds add a nutty richness and great texture. Use raw or roasted pepitas depending on your preference.

Garlic: Two cloves provide a bright, savory bite.

Parmesan cheese: Freshly grated Parmesan adds salty, nutty depth. If you want a dairy-free option, substitute nutritional yeast (see FAQs).

Lemon: A squeeze of fresh lemon juice brightens and balances the pesto.

Salt and pepper: To taste—these lift and round the flavors.

Extra virgin olive oil: Use a good-quality olive oil for a smooth emulsion and rich mouthfeel.

Cold water: Optional—used to thin the pesto without adding extra oil if needed.

Equipment

Food processor or blender: A standard food processor gives the most control. High-powered blenders work as well.

Grater: A microplane or box grater for finely grating Parmesan if you’re not using pre-grated cheese.

Chef’s knife: To roughly chop garlic and halve the lemon.

How to make pepita pesto

Fit your food processor with the standard blade. Add pepitas, basil leaves, garlic, grated Parmesan, lemon juice, salt, and pepper. Pulse on high for 5–10 seconds until everything is very finely chopped.

With the motor running on low, slowly stream in the olive oil until the pesto emulsifies and becomes smooth. If the texture is too thick, add 1–2 tablespoons of cold water while blending to loosen it. Taste and adjust seasoning with additional salt or pepper as needed.

Transfer to a jar or airtight container and refrigerate. Pesto will keep in the fridge for up to about 7–10 days; it can also be frozen for longer storage.

FAQs

Can I make this dairy-free?

Yes. Omit the Parmesan and substitute 1/4 cup nutritional yeast for a savory, cheesy flavor to make a vegan pesto.

Can I use something besides pepitas?

Yes. Pine nuts, cashews, walnuts, almonds, or sunflower seeds can be used as alternatives.

How should I store this and how long does it last?

Store in an airtight container or mason jar in the refrigerator for up to 7–10 days. You can also freeze portions for several months; thaw in the fridge before using.
