Why Pumpkin Seed Pesto Is Trending in 2026

Key Ingredients in a Pumpkin Seed Pesto Recipe
You only need a handful of fresh, simple ingredients to pull this together.
- 3 oz of fresh basil
- 2 oz of fresh spinach
- 1 lemon (zest and juice)
- 3 cloves of garlic
- 1/4 cup of pepitas or nuts of your choice
- 1/4 to 1/2 cup of neutral oil (vegetable or canola)
- Salt and pepper to taste
Step-by-Step Guide: How to Make Pumpkin Seed Pesto
Follow these six steps and you'll have a vibrant green sauce ready in under 10 minutes.
Step 1: Separate Fresh Basil Leaves
Start by measuring and separating about 3 oz of fresh basil leaves from the stems. Use only the tender green leaves. Discard any wilted or brown ones.
Fresh basil is the base of this pumpkin seed pesto recipe. It gives the sauce that classic herbal flavor and bright green color.
Step 2: Prepare Lemon Zest and Juice
Grate the zest from one fresh lemon first. Stay close to the surface and skip the white pith, which tastes bitter.
Then cut the lemon in half and squeeze out all the juice. Both the zest and juice matter here. They add brightness and balance to the rich, nutty flavor of the seeds.
Step 3: Add Basil to the Grinder
Place the basil leaves into a grinder or food processor. This is the aromatic base of your pesto. Keep the leaves loosely packed so they blend evenly.
Fresh basil releases its natural oils when processed, which is what gives this pumpkin seed pesto recipe its deep herbal flavor and vivid green color.
Step 4: Add Garlic, Seeds, Oil, and Spinach
Now add 3 cloves of garlic, 1/4 cup of pepitas, 2 oz of fresh spinach, and 1/4 to 1/2 cup of neutral oil into the grinder with the basil.
This step builds the body of the sauce. The pepitas add creaminess. The spinach boosts the green color. The oil brings everything together into a smooth, rich blend.
Step 5: Season with Salt, Pepper, and Lemon
Add salt and freshly cracked black pepper to taste. Then pour in the lemon zest and juice. This step is what balances everything out.
The seasoning brings out the nuttiness of the pepitas. The lemon keeps the pesto tasting fresh and light, not heavy or greasy.
Step 6: Grind Until Smooth and Serve
Run the grinder until the mixture is smooth and creamy. Stop a few times to scrape down the sides. This ensures everything blends evenly.
Once it looks glossy and well combined, it's ready. Your pumpkin seed pesto recipe is done and good to use right away.
