NO NUT PUMPKIN PESTO

As Americans, we usually think of pesto in the green, garlicky Genovese style, but there are heaps of variations throughout Italy. I love traditional pesto (and Sicilian pesto agli agrumi), though the olive oil and cheese make it a Deceptively Indulgent Sauce. This pesto, while still creamy and flavorful, offers a low fat, low acid option intended to be gentler on digestion.

Boyfriend is allergic to pine nuts, which are traditionally used in pesto alla genovese. We were out of our usual alternatives (almonds, cashews, pistachios, walnuts) but had plenty of raw pepitas-style pumpkin seeds on hand. We ended up preferring them over walnuts, and they are much cheaper! After further experimenting with pumpkin, this pesto sauce tastes great paired with savory autumnal treats or topping filled pasta like tortellini.

SO CREAMY & SEEDY

Prep:

20 min

Blend:

5 min

Total:

25 min

Makes roughly 2 cups in volume. Servings estimated at ¼ cup (~50 ml), so 8 servings.

FUN FACTS:
  • The name “pesto” derives from the act of preparing the sauce via crushing or pounding the ingredients. Originally, this would have been done with a mortar and pestle. Many people do this today to wonderful results, though it takes a lot of time, patience, and fine motor skills.
  • Although most nuts and seeds are more acidic in pH, pumpkin seeds are surprisingly alkaline and a good source of zinc, which can be helpful with acid reflux!

INGREDIENTS:

  • ¼ cup raw pumpkin seeds
  • 2 packed cups fresh basil*
  • ½ cup pumpkin puree** (either prepared from fresh or make sure it is 100% canned pumpkin puree, not the pie filling with added sugars)
  • ¼ tsp coarse salt

*If you don’t have your own plant, basil is pricey in your area, or find it hard to get fresh basil depending on the season, you can sub in 1 cup of alternative greens, such as arugula/rocket, baby spinach (with the stems removed), blanched kale, Italian parsley…just make sure you have around 1 cup of basil for flavor.

      [Optional] 

  • ¼ teaspoon ground allspice – It added a nice, subtle grounding to the sauce, especially if not using olive oil at all, since olive oil can have the slight bitter, spicy tones to it like a wine can.
  • ¼ cup nutritional yeast, which adds a nutty, cheese like flavor
  • ¼ cup grated parmesan or pecorino sardo if you eat cheese and don’t have nutritional yeast.

**Skeptical about nixing the olive oil? Feel free to use ½ cup extra virgin olive oil instead of pumpkin, or ¼ cup pumpkin puree and ¼ cup extra virgin olive oil. One of best things about pesto is that it so easy to customize! The nutrition facts at the bottom of the post will tell you the ratios for the ½ cup pumpkin compared to ½ cup extra virgin olive oil.

STEP BY STEP:

  • OPTIONAL: Some people recommend blanching basil before making pesto, which preserves the vibrant green color and prevents browning. This may be a good option if you plan to refrigerate your pesto for the next few days, or even freeze it for later use. I skip this step if we’re going to use all the pesto at once. To blanch basil, set a small pot of water to boil. Nearby, fill a medium sized bowl with ice. Using a handheld strainer, submerge and swirl the basil in the boiling water for no more than 15 seconds, then plunge the herbs into the ice bath. Remove them from the ice bath, blot with paper towels, and set aside to dry. You can use the aromatic basil water to boil pumpkin seeds, thin out the pesto sauce, or save/freeze it to add to future batches of risotto or sorbet.

  • 1. Either soak the ¼ cup of pumpkin seeds overnight, or boil them in a small saucepan full of water for at least 15 minutes. Afterwards, strain the water, reserve ¼ cup water aside, pour the seeds into a bowl and let them cool completely. Boiling or pre-soaking seeds allows them to blend into a creamy consistency.

  • 2. Clean your produce. Make sure your herbs are as dry as possible before you blend them. If using basil from a live plant, remember to clip it off at the top where the leaves grow (at the node) so the leaves can grow back big and healthy! Slightly tear the basil leaves before adding them into the blender/food processor.

  • 3. Pulse the cooled pumpkin seeds in the processor about 10 times. Next, combine pumpkin puree, ¼ cup nutritional yeast/cheese, basil, salt, and allspice (if using) into your blender/food processor. Blend until well combined. If you aren’t using oil and find your pesto to be a bit thick, use some of the reserved water from boiling the seeds to thin it out and blend further. If using olive oil, stream the oil bit by bit through an opening in the top your blender/food processor so it emulsifies. (3 minutes). Enjoy your pesto and check out some recipe ideas below the photo gallery!

  • Note:  Basil is a more delicate, aromatic herb usually ended at the end of cooking, so to preserve flavor it’s better to add the sauce to your cooked food right before serving. Tossing it all together will warm up pesto; make sure a previously frozen batch gets defrosted ahead of time. I like to let my pesto sit at room temperature while cooking the main dish.

MEAL IDEAS

  • Omnivore: For one meal, we simmered cubed chicken breasts, minced garlic, plus carrot strips in garlic, and olive oil while cooking pasta at the same time. After the pasta was cooked, we tossed everything together with quite a bit of pesto (I prepared 2 servings of pasta). All in all, everything took less than 30 minutes. Shrimp would also be a good protein option.
  • Vegetarian: This lean, green pesto tastes awesome with stuffed pasta like tortellini or ravioli, particularly cheese, mushroom and butternut squash varieties. A pasta dish with farfalle, cremini/porcini mushrooms, green peas, garlic and some freshly grated parmesan cheese makes some satisfying comfort food.
  • Vegan: Besides suggestions full of pasta dishes, roasted chickpeas, cauliflower, garlic, pearl onions, and yellow bell pepper would be lovely tossed together with the pesto and served with pearled couscous, farro or rice. Pasta made with legumes can add a great boost of protein for plant-based diets.

If you are not planning to use all the pesto immediately, I recommend freezing it for future use (defrost in the fridge). Leftovers will be fine in the fridge for up to 48 hours.
