🌿 Ingredients

  • Basil: Basil has a strong, pungent flavor with hints of anise (licorice-like). It can be purchased in-stores or easily grown in your garden. Basil is the main ingredient in pesto, and provides us with antioxidants and nutrients such as vitamins A, K, and calcium.
  • Pepitas: The crunch from pepita results in nut-free pesto without sacrificing any of the flavor or texture. Pepitas have heart healthy fats and are loaded with nutrients such as iron, magnesium, and zinc (USDA Food Nutrient Database). Pepitas are specifically harvested from a variety of pumpkin that does not have a hull on the seed. In cooking applications that use pepitas within the recipe (versus as a garnish), be sure to use actual pepita seeds. When garnishing a meal, pepita or pumpkin seeds can be used interchangeably.
  • Cheese (or nutritional yeast): Parmesan cheese is traditionally used in pesto, but if you’re making a cheese-free pesto then substitute it for nutritional yeast for a savory and nutty flavor.
  • Olive oil: Oil keeps pesto from becoming a thick sauce and helps to thin the emulsion in order to best coat your food. The oil also adds flavor to the pesto, so be sure to choose a good quality olive oil.
  • Garlic, salt, and pepper: Garlic, pepper, and salt are the traditional seasonings for pesto. Add garlic and pepper while processing your pesto and then season with salt to taste.
  • Optional ingredients: Bring a bit of acid to your pesto with a splash of lemon at the end.

πŸ₯£ How to make (step-by-step photos)

1️⃣ Step One: Wash and prep basil

The first step is to prep and clean the basil by washing under running water, or adding to a bowl of water and swirling it around to remove dirt.

Once the basil is clean, lay it flat to dry or spin it in a salad spinner.

3️⃣ Step Three: Add nutritional yeast, spices, and lemon juice

Finally, add in nutritional yeast, salt, and pepper and do a taste test for flavor. Add more salt or pepper as needed, and top it off with a squeeze of lemon juice (optional).

Then serve on top of roasted vegetables, over pasta, as a sauce for pizzas, or drizzled into soups and stews!
