Why I love this spinach pesto recipe

You guys know that I like pesto right? Are you sure? Ok. Because if you don’t already know, I’ll be glad to tell you again. I love it.

I mentioned last week, when I posted my recipe for Smoked Turkey Pesto Pasta Salad, that I would share my recipe for my favorite pesto sauce, spinach basil pesto, and now I am. It really is my favorite.

It’s my favorite because it’s the best. It’s the best because it’s adding the spinach makes the basil go a lot farther, and basil can be expensive. Even when I grow my own, there’s never enough.

Other than the usual pesto ingredients, this recipe calls for nutritional yeast. If you’ve never used it before, it’s a dried, flakey ingredient that you can find in the organic or natural section of your grocery store. You can also find it online, but keep in mind that it will most likely be a bit pricier.

What is a substitute for pine nuts in pesto?

This recipe makes it easy for you to enjoy any of your favorite pesto-based meals for a lot cheaper. It’s a 2:1 ratio of spinach to basil, so whatever you make will be extra green.

I also opted to skip the traditional pine nuts – although you’re more than welcome to use them yourself if you want – and I went for walnut pieces this time. In the past, I’ve used sliced almonds and even shelled pistachios in a pinch.

You really can’t go wrong, but I would steer clear of straight up peanuts since the flavor is so overwhelming.

How to make pesto with spinach

Measure and prep your ingredients. Trim any large stems from your basil and spinach, and peel or press your garlic if you need to (although I usually just pop in the whole clove or use pre-minced).

Blend your pesto ingredients. Combine all of the ingredients into the bowl of a food processor. Scrape the sides with a spatula once or twice to make sure everything is blended smoothly.

Adjust your seasonings with salt & pepper. You can also add extra olive oil to thin the pesto sauce if you need to, or if you prefer your pesto to be a bit thinner.

Store in an airtight container. If you aren’t serving the pesto immediately, transfer it to container and place it in the fridge until you’re ready to use it. It should stay good for up to a week (as long as you used fresh ingredients).

FAQs about spinach basil pesto

What is pesto sauce made of? Traditionally pesto is made from basil, pine nuts, garlic, parmesan cheese and olive oil. I swapped the cheese for nutritional yeast and the pine nuts for walnuts. I also added spinach to give it a little extra green.

Does pesto need to be cooked? No. You shouldn’t normally cook your pesto because it changes the flavor of the fresh basil, but I have used it as an ingredient in marinades and to season proteins before grilling them. Usually when I do this, I add more pesto after the cooking process to give it even more flavor.

What can I use instead of basil in pesto? Obviously, I’ve added spinach to this recipe to give us more bang for our buck when it comes to the basil, but if you don’t want to use basil at all, you can easily substitute it for another herb (like cilantro or parsley) or use more spinach.

Do vegans eat pesto? Since traditional pesto is made with cheese, vegans shouldn’t eat it, but since this recipe uses nutritional yeast instead of cheese, this is safe for vegans, or anyone avoiding dairy, to eat.

Tips for making the best pesto sauce

Use a good quality olive oil. I recommend trying extra virgin olive oil because it has the most flavor.
If you’re using whole nuts, chop them a bit before adding them to the food processor. This helps prevent the pesto from turning into a nut-buttery paste.
To keep the pesto from browning, keep the air out. Use the smallest container you can, or use a layer of plastic wrap to keep the air out.
