    What is gluten-free pesto made of?

    Traditionally, pesto in its simplest form is made by crushing a few key ingredients together. The original forms of pesto are from Genoa and Sicily, respectively as pesto al Genovese (basil pesto) and pesto rosso (pesto with sundried tomatoes).

    Pesto sauces are made with numerous different ingredients, usually a combination of basil, nuts (mostly pine nuts), Parmesan (or pecorino)cheese, garlic, and olive oil. These ingredients are all naturally gluten-free, so if you’re using a homemade or store-bought pesto made with these ingredients, you’re good to go.

    Watch out for additives and alternative ingredients

    Like I’ve said above, it’s important to be aware that some store-bought pestos may contain additives or alternative ingredients that contain gluten.

    For example, some manufacturers may add wheat-based thickeners or flour to their pesto to give it a thicker consistency. Try to avoid pesto with ingredients that contain gluten like yeast. Yes, it is naturally gluten-free but some manufacturers do include wheat flour or wheat starch in it(especially dry).

    Additionally, some variations of pesto may include ingredients that contain gluten. Examples may include, sun-dried tomato pesto (not all brands) or pesto made with nuts other than pine nuts may contain gluten. So be sure to check the ingredient list to understand all the ingredients in your pesto and also look for a gluten-free label to be sure.

    Homemade pesto is the way to go

    Most of the pesto you encounter in the U.S. is different for a few reasons. First off, most of what you see here is made by machine, usually a food processor or hand blender.

    This holds true even if it is homemade. Which still can taste reasonably good, but because the ingredients aren’t hand-chopped you end up with a texture that is more like a moist paste and there is little to no definition between ingredients.

    The same applies to gluten-free pesto. If you’re looking to be extra cautious, the best option is to make it yourself at home. This way, you will better have control over the ingredients you use in your pesto and can be sure that everything is gluten-free. Plus, homemade pesto (honestly in my opinion) is often fresher and more flavorful than store-bought varieties.
