How to substitute pesto, step by step
- 1
Pick the right substitute for the job
For most recipes use Nutritional yeast + cashew pesto — pasta and sandwiches. If you need a different texture, Miso pesto works for deeper savoury note.
- 2
Measure using the correct ratio
1:1. Weigh rather than eyeball it — small errors show up much faster when replacing pesto.
- 3
Adjust the method
Add a splash of pasta water when tossing — vegan pesto is thicker and needs loosening.
- 4
Taste and correct
Plant swaps are usually a little less salty and less rich than pesto. Season at the end and add acid (lemon, vinegar) or umami (miso, nutritional yeast) if the dish tastes flat.
Mistakes to avoid
- Swapping by volume when the recipe measures pesto by weight — check the ratio above first.
- Using a sweetened or flavoured version in a savoury recipe.
- Ignoring the method change: Add a splash of pasta water when tossing — vegan pesto is thicker and needs loosening.
- Assuming every packaged product labelled "plant-based" is vegan — some still contain milk powder, honey or egg. Scan the barcode to be sure.
Conversion ratio

Replace the job, not just the ingredient
An egg can bind a burger, enrich a cake or create the foam in a meringue. Those jobs need different substitutes: ground flaxseed can help with binding, while aquafaba is useful for whipping.
Review the rewritten method as well as the ingredient list. Changing the amount of liquid, the cooking temperature or the resting time can matter as much as the substitute itself.
- A practical example
- For a creamy pasta, try unsweetened plant cream or blended silken tofu; add acidity and seasoning to taste rather than relying on a cheese substitute alone.
- What to keep in mind
- Substitutions can change allergens, texture and nutrition. Test a small batch before making a dish for guests.
