Let’s Make Oil-Free Pesto
Time to whip up this homemade oil-free vegan pesto! At home, you can use a blender, food processor, or a bullet blender to make pesto very quickly. Of all the kitchen appliances we have tried, we favor our food processor to make pesto.
Here’s the thing, many high powered blenders have a minimum capacity in order to reach a smooth, blending consistency. In our Vitamix, we need to make about 2 cups of pesto (double this recipe) for the blender to work well– and if we don’t have that much basil lying around…. it doesn’t work and we end up switching to the fp…. and washing more dishes.
You can make this recipe without a food processor– simply use a bullet blender or double the recipe for a full-size blender. Or go full-blown authentic with it and use a mortar and pestle.
The ingredients you need to make oil-free vegan pesto are usual suspects in most vegan kitchens:
- Fresh basil
- Lemon juice
- A couple cloves of garlic
- Nutritional yeast
- Nuts
- Salt & pepper
- Avocado
- Water
On Cooking & Eating
How to use pesto? We use pesto in a lot of different ways around our kitchen… some traditional and some full-on, out there unconventional. Fresh pesto has huge flavor, we usually use this for run-of-the-mill meals that need a little pizzaz!
Here are some ideas on how to use leftover pesto:
- Pizza sauce
- Pasta sauce–oil-free pesto pasta, or even in a lasagna
- As a dressing for a grain bowl– rice & veggies topped with pesto
- On toast. Yes, we do this.
- Use it to flavor hummus or other dips
- Add it to a tofu or chickpea scramble in the morning
- As a spread in quesadillas or sandwiches
- Use as a dressing for cold pasta salads- pesto pasta salads are delicious in the summertime
Also, it’s really up to you on whether on not to toast the nuts/seeds you use. The pesto will definitely have a more pronounced, nutty flavor if you toast them.
If you want to take a swing at toasting the nuts for your pesto, toast in a skillet over medium heat for 7-9 minutes stirring frequently until nuts are golden and fragrant. Alternatively, place on a cookie sheet in a 350* oven for 9-11 minutes, removing every 3 minutes to stir.
Be careful! It’s incredibly easy to burn nuts when you intended to toast them!
Is Pesto Vegan?
Pesto is traditionally a fresh basil and olive oil sauce, right? What makes pesto not vegan? Parmesan cheese is traditionally and commonly used in pesto today, which is why most pesto recipes are not vegan.
In this oil-free pesto recipe, we will replace the parmesan cheese with nutritional yeast to achieve the same cheesy, nutty, acidic quality that parmesan cheese lends to traditional pesto.
We’re also going to use avocado to replace the olive oil. Avocados have a smooth, creamy texture and their high-fat content will replace olive oil beautifully.
Troubleshooting Oil-Free Pesto
This sauce seems easy enough- what could possibly go wrong? Most sauces made in a blender or food processor are forgiving as you can blend the ingredients, taste test, and adjust as needed. This recipe allows you to do exactly that! I’ll often taste and add a pinch of salt and another dash of lemon juice.
Why is my pesto bitter? This can happen for several reasons, the culprit is usually basil! (Surprise!) Some varieties of basil leaves are more bitter than others and off-season basil can have more bitter notes. If your pesto has a very bitter taste try adding more lemon juice (acid), nutritional yeast (flavor), or nuts (fat + flavor). If this doesn’t curb the bitterness, try adding a few springs of another herb like parsley or cilantro to help counteract the bitterness.
Why is my pesto turning brown? Pesto will oxidize and turn from a bright, cheery green color to dark, muddy green- just like guacamole does. This is completely normal and the pesto is still ok to eat and will taste delicious! Especially as we are using avocado as the main fat component of this sauce, the pesto will turn brown!
Is there a substitute for nutritional yeast? Use miso as a nutritional yeast substitute! Miso gives a satisfying, umami flavor but it doesn’t provide the same level of ‘cheesiness’ that nutritional yeast does.

I only had super tiny avocados so I used a whole one and added a little extra water- we used it with pasta and had some leftover that we added to eggs in the morning. Both ways it was really great.

I made this last night with a few adjustments. I used both walnuts and pine nuts ~ 1/2 cup, 3 garlic cloves, a whole avocado, a whole lemon and no salt. It was great! I never would have thought to use an avocado. Will definitely make this again!!

This is the best oil free vegan pesto I’ve tried. I’ve been trialling a few lately as I wanted to cut out oil. This is by far the best one, many thanks for posting. I changed the salt for miso as I’m cutting out salt aswell. It tasted lovely still.
