Vegan Pesto Sauce
Nutrition
This vegan pesto sauce recipe, bursting with flavor, offers a guilt-free pleasure for serving your family. Its versatility shines through, especially for lactose-intolerant family members, as it cleverly substitutes cheese with nutritional yeast. This adaptation ensures everyone can enjoy its rich, savory taste without compromise.

I’ve shared in the past about my journey with vegetarianism and veganism. For nine years, I embraced this lifestyle, but eventually, I frequently dreamed about eating meat. This recurring theme led me to believe that my body was signaling a need for more protein, prompting me to reconsider my dietary choices.
But I didn’t stop using nutritional yeast. I love the taste, and the recipes I most use it in are soups.
Nutritional yeast and its uses
Nutritional yeast is a deactivated yeast with a robust flavor. If you haven’t had it before, it tastes cheesy and nutty. Like some cheeses, it can also be pungent and earthy-tasting.
That makes it perfect to add to various sauces where you might otherwise use cheese. It is also delicious, sprinkled on salad, popcorn, vegetables, and more.

Helpful tips
- When replacing cheese with nutritional yeast, start with a small amount and adjust according to your taste. Nutritional yeast provides a cheesy, nutty flavor without dairy.
- While traditional pesto uses basil, feel free to experiment with other greens like parsley (like I did), spinach, kale, or arugula for different flavor profiles.
- Pine nuts are a classic ingredient in pesto, but they can be pricey, so I used pistachios and walnuts. Other options include almonds, cashews, or sunflower seeds.
- Use less oil and add more to achieve your desired consistency for a thicker pesto. This makes it adaptable for various dishes, from pasta sauces to sandwich spreads.
- Fresh ingredients are key for the best flavor. Fresh basil, fresh parsley, and quality extra virgin olive oil enhance the taste.
- Vegan pesto can be stored in an airtight container in the fridge for up to a week. For longer storage, freeze it in ice cube trays for easy portioning, or put it in a glass jar in the freezer for up to two months.
- A splash of lemon juice not only adds a bright flavor but also helps maintain the vibrant green color of the pesto. Adjust the acidity to suit your palate.
- Start with a small amount of garlic and adjust according to your taste, as raw garlic can be quite potent. I am using garlic paste as it comes in a tube and is easy to dispense.
- If you’re using salted nuts, adjust the additional salt in the recipe accordingly to avoid an overly salty pesto.
- Feel free to add extras like sun-dried tomatoes, roasted red peppers, or chili flakes for an added flavor dimension.

Your pesto is fantastic! I had not seen nutritional yeast in that nice glass bottle of theirs yet. Very good to know. I don’e really need those large containers.
Thanks so much Ginny. I appreciate it!
This was simply scrumptious! I love the naturally brilliant emerald color and the addition of nutritional yeast! (Which is also super yummy on popcorn!)
Thanks, Rebecca! I love it on popcorn!
Excellent idea to swap the cheese for the nutritional yeast! It was fantastic, as usual, Elaine!
Thanks so much Beth! 🙂
I love that the spices are organic. I put the pesto on pasta, which was amazing!
Thank you Dawn, I appreciate it!
Totally trying to take cheese out of my diet. This pesto was great and love the nutritional yeast and didn’t miss the cheese!
It is a great replacement Carol. Just don’t expect it to ‘melt’, it just gives the flavor! Thank you for your comment! 🙂
I love that Simply Organics has flakes and not powder. Great pesto. Thanks!
