Tip for best results

Make this with freshly grated Parmesan cheese, instead of the stuff in the green can. There's no need to grate by hand if you have a blender or food processor.

Just cut up a Parmesan wedge into large chunks, toss them into the machine, and pulse until you have a nice consistency. (I use speed 7 on my Vitamix (affiliate link) and keep that grated cheese in the fridge for weeks.

Instructions

  • If you need to grate your cheese, cut up your Parmesan wedge into chunks and put them in your food processor or blender. Chop them until the cheese is the right consistency. Rinse your spinach, if needed, and pat dry.

  • Add the spinach and all ingredients to the bowl of the food processor. Pulse until you have the consistency of a smooth paste, stopping once to scrape down the sides of the bowl.

  • Serve the pesto stirred into cooked pasta or use it as a topping for pizza, chicken or salmon. (See notes for ideas.) Store the pesto in the refrigerator up to one week or freeze it for longer.

Notes

  • For ideal texture, use a food processor instead of a blender. If you only have a blender, just pulse the ingredients instead of letting your blender run for too long, or you will end up with more of a liquid texture instead of a paste.

    I can't believe it but I actually grew basil this year...it's normally too cold here and it only lasts a few weeks. It is so nice to have fresh basil! But I love the looks of this spinach pesto, especially that you don't need to cook it first. Looks so delicious!

      Yay for basil! You can freeze it too, if you have enough and want to make it last. But this spinach pesto has a really nice flavor and is so easy. I'm thinking about making a few batches to freeze and have on hand. Thanks, Denise!
