    Making your own homemade pesto sauce doesn't have to be difficult. In fact it's so quick and easy that you'll never buy pesto again. This low sodium pesto sauce uses fresh herbs and ingredients that adds flavor to almost any savory dish. It comes together with only 9 ingredients and it only takes seconds to make in a blender or food processor.

    Most store-bought pesto products are loaded with preservatives and have too much sodium. Some can even average over 500 milligrams of sodium per serving size! Traditional pesto is made with garlic, nuts, salt, basil leaves, parmigiano-reggiano, and extra-virgin olive oil. This low sodium pesto recipe puts a little twist to the pesto sauce. It uses avocado to add in some healthy fat, spinach for extra nutrients and is made with dairy free cheese. But don't worry, it's full of all the flavors you love in a pesto sauce that are herbal, nutty and garlicky with no added salt. 

    You can add it to your favorite homemade pasta dishes, protein, pasta salads, and more with this versatile spinach pesto. So, say no to the bottled pesto sauces and make your own healthy pesto sauce with less sodium right at home.

    Equipment You'll Need

    • Measuring Spoons - for measuring the ingredients

    Ingredients You'll Need

    To make this homemade version of pesto, you'll need good quality fresh produce for the best results. Here's what you'll need: 

    • Basil -   look for fresh basil leaves with green leaves and a fragrant smell.
    • Spinach -  fresh spinach adds color and you get extra iron from the leafy greens. 
    • Avocado - you'll only need ½ of a large or 1 whole small avocado. 
    • Garlic -  using just 2 fresh garlic cloves adds a noticeable garlic flavor. You can adjust for your taste preference. 
    • Pine nuts - too help bring out the savory flavor in the pesto
    • Lemon juice - for a little acidity 
    • Olive oil - to help enhance the flavors and texture of the pesto. Make sure to use extra virgin olive oil.
    • Water - only 3 tablespoons is needed however this will vary based on the consistency of the sauce you like.
    • Parmesan cheese - this vegan pesto uses dairy free parmesan cheese. You can also use nutritional yeast or feel free to use your favorite parmesan cheese.

    How to Make Low Sodium Pesto

    1. Add  the basil, spinach, avocado, garlic, pine nuts and lemon juice to a food processor.
    2. Pulse for 20 seconds or until the pesto is combined. Slowly add the olive oil to food processor and pulse for about 10 - 15 minutes to combine.
    3. Pour in the water and process again until completely smooth. You may like to add more water to get it to your desired consistency.
    4. Transfer to a bowl and stir in the dairy free parmesan cheese.
    5. Taste and adjust the seasonings as needed.
    6. Refrigerate until ready to use.

    How to Store

    • To Store - The pesto can be stored in an airtight container in the refrigerator for 2-3 days. 
    • To Freeze -  If you make a big batch of the pesto and have leftovers, it freezes well and can be stored in a freezer-friendly container for up to 1 month. You can even use ice cube trays that come with a lid, to store the sauce in.
    • To Reuse - When you're ready to use it, let it defrost in the fridge overnight before using.  The pesto will thicken in the fridge. You can thin it with a little water or just enjoy it as-is. Serve it with your favorite pasta or protein dish.

    Is It a Thyroid-Friendly Recipe? Avocados are loaded with healthy fats and are a great source of potassium, folate, fiber and contain anti-inflammatory and antioxidants. Spinach is a nutritious leafy, green vegetable that is rich in multiple vitamins and minerals and is linked to numerous health benefits that may help improve your eyesight, cancer prevention and help to regulate blood sugar. All which help to maintain the hormonal balance for proper thyroid function and boost your immune system.

    Recipe FAQ

    What does pesto taste like? 

    Pesto tastes like a creamy, nutty lemony, garlicky basil sauce.

    How do you reduce salt in pesto?

    There is no salt added to this pesto. You can add an extra squeeze of fresh lemon or add in more parmesan cheese to help balance the flavors if preferred.

    What could I use instead of a food processor?

    A high powered blender works great! Just make sure to scrape down the sides with a spatula as needed while blending.

    Does avocado pesto turn brown?

    Avocado oxidizes (turns brown) when exposed to air. I recommend storing the avocado pesto in a container with a little lemon juice on top and covering it with plastic cling wrap before sealing the container with the lid.

    How can I reduce my salt content?

    Focus on eating more whole food like fruits and vegetables. Read any packaged foods or sauces you may purchase from the grocery store and check how much sodium is in it. Also, when buying packaged foods, like soups, broths or sauces, see if they have a low-sodium option.
