So fresh and vibrant, this nut-free Easy Pumpkin Seed Pesto is super quick to make and incredibly versatile. With a creamy, slightly textured consistency, it’s a delicious addition to everything from pasta to pizza, grilled veggies, soups or sandwiches, eggs and more.

This is not your average pesto recipe. Imagine lots of fresh leafy greens, bright lemon, sweet basil, garlic and nutty Parmigiano Reggiano combined with nutrient-rich pumpkin seeds for a slightly chewier texture.

Here’s everything you’ll need to make this Easy Pumpkin Seed Pesto

2 cups (65 grams) baby spinach
1 cup (20 grams) arugula
¼ cup (6 grams) fresh basil
¼ cup (15 grams) fresh parsley
2 to 4 garlic cloves, peeled
1 to 2 tablespoons (10-15 grams) fresh squeezed lemon juice (about ½ lemon)
¼ cup (20 grams) pumpkin seeds
½ cup (50 grams) Parmigiano Reggiano, chopped, sliced or grated
½ teaspoon (3 grams) coarse sea salt
½ cup (125 grams) extra-virgin olive oil

It starts with a combination of baby spinach, arugula, basil and parsley to produce a pesto that’s packed with beneficial nutrients and rich in colour.

I use pumpkin seeds (pepitas) in a variety of recipes and always have them on hand. They’re a great source of calcium and make such a lovely, crunchy addition to so many dishes.

🌻 How to unlock the best flavour

While you can absolutely use raw pepitas straight from your pantry, taking three quick minutes to toast them completely transforms the pesto!

Pop your pumpkin seeds into a dry skillet over medium-low heat until they just begin to turn fragrant and pop.

This light toast releases their natural oils, cutting down any raw bitterness and giving your pesto an incredibly rich, nutty depth.

Let them cool completely before blending them into your leafy greens.

Variations & substitutions

This recipe is completely customizable using whatever greens, herbs, nuts or seeds you have on hand. A great staple to have in your rotation year-round, just use the measurements below as a guide.
If you don’t have pumpkin seeds, almonds, hazelnuts and walnuts all work well and sunflower seeds are a great nut-free alternative.
This pesto can be made ahead of time and stored in a well-sealed container in the refrigerator for up to 3 days.
It’s freezer friendly. Spoon it into an ice cube tray then transfer the individual portions to a zip-loc bag or air-tight container for future use. *If using from frozen, just be sure to bring the pesto to room temperature before serving.

🌿 Herb storage tip

Leafy herbs like basil, cilantro and parsley are best stored on the counter in a tall glass with a little water. Just change out the water every couple of days and they will thrive!

This nut-free Easy Pumpkin Seed Pesto is such a great way to get your greens in or to use up that stash of herbs and veggies you have in your kitchen. All you have to do is blitz everything together in a 4-cup food processor like this one and you’re good to go. Try it with kale, cilantro or fresh tarragon!
