Ingredients Needed for an Absolutely Delicious Dairy Free Pesto Sauce

Fresh Herbs - this is the main ingredient, for this recipe the herb we are going to use is basil. But you could use sun-dried tomatoes, spinach, parsley, cilantro or any leafy herb or vegetable.

Nuts - Cashews are the best choice for as a non dairy substitute for cheese in this Paleo pesto sauce because cashews taste the closest to parmesan cheese. Of course you can use any nut you like.

Oil - You always want to use the freshest and finest oil. Extra Virgin Olive Oil works best if you are making a Basil Pesto. You want to match the oil with the type of pesto you are making. Other options are avocado oil, truffle oil, sesame seed oil, etc

Garlic - garlic is the heart of any good pesto sauce. Always use freshly, crushed garlic. Crushing the garlic brings out the boldness of the garlic. Some even sauté the garlic, this isn't necessary but optional if you want to take this extra step

Salt and Pepper

Vinegar or lemon juice how about lime juice1(00% optional)

Note: While I don't personally add lemon juice or vinegar to my basil pesto sauce you may wish to include them. Aside from keeping the basil from discoloring, I don't feel that it adds flavor worth including it as an ingredient. But, that's just my opinion!

So, if you want, I'll leave it up to you to decide whether you want to add lemon juice or not, this is totally optional.

Instructions on How to Make Dairy Free Pesto

The easiest way to make pesto is by using a food processor or mini-food processor. That's what I use. Depending on how much pesto you are going to make you can use a regular size food processor.

Saute some garlic in olive oil until lightly brown and set aside.

Place cashews or nuts into a food processor and chop until ground fine but coarsely.

If you don't have a food processor, don't worry. You can also use a hand mixer.
For those of you that don't have a food processor, you can finely chop up the basil with a knife or scissors.

Of course, if you have a mortar and pestle you can also use it to finely grind the basil and then take it from there. Add remaining ingredients and Bob's your uncle.

Add the basil to the food processor with the cashew and add the garlic. Chop until ingredients are ground finely. Remove ground ingredients and place into a bowl.

Use immediately or store in a sealed container in the refrigerator.

In this dairy free pesto recipe we substitute pine nuts with cashews as a substitute because cashews have a cheese taste. This basil pesto recipe is refined sugar free, soy free, gluten free, keto and dairy free and its an easy vegan pesto sauce recipe.

What is Pesto Sauce Used For?

Here are some ways to use pesto sauce:

spaghetti squash (aka Whole30 spaghetti)
vegetables
dips
spreads
pizza sauce
grilled/baked salmon, seafood

Unlike other sauces, pesto sauce doesn't require any cooking. One thing you want to consider when you are using Basil to make a pesto is the final taste.

Fresh basil tastes much different than cooked pesto. And usually, the Basil Pesto sauce is added to spaghetti or vegetables just prior to it being served, but you don't actually cook with it.

The only exception might be if you are making a pizza and are using it as a pizza sauce. Then you would spread the pesto over the pizza dough and bake it.

Serving on Vegetables - Use this pesto over grilled vegetables. Once your vegetables are ready, you can pour the sauce over your vegetables and toss to combine.

You can also brush on the pesto if your vegetables are cut into large pieces.

Serving over Spaghetti Squash - Place your cooked spaghetti squash in a pan and heat to cook off the water. Turn heat off and pour pesto over squash and mix to combine.

Serving over Pasta - When it comes to pasta, it's all about that wonderful starchy pasta water! Always reserve some of your past water when you drain your pasta. I recommend saving about 1 cup.

Do not rinse pasta! If you rinse the pasta you will wash away the starch that helps the sauce to stick to it. Once your pasta is drained, place it back in the pot and pour the pesto sauce over it. Mix the pasta to combine the sauce. Use the reserved pasta water if your pasta starts to stick together or clumps up!

Equipment Needed to Make Basil Pesto

Equipment plays a large role in ensuring that your recipe turns out well. This recipe doesn't call for a lot of ingredients. You can use a food processor, a mini food processor or a mortar and pestle.

If you plan on making a large portion of pesto sauce, you'll also need some miniature mason jars.

How Long will Fresh Homemade Pesto Sauce last?

Because homemade pesto sauce has no preservatives it will not have a long shelf life. You can store pesto refrigerated for 5 -7 days in the fridge. Always make sure that there is sufficient oil to submerge the herbs/ingredients.

You can also freeze it in a freezer safe container and thaw it out overnight in the freezer when you are ready to use it.
