Making and freezing basil pesto in a great way to preserve the fresh flavors of summer. Healthy and versatile – pesto is perfect brushed on grilled meats, tossed with steamed veggies or stirred into soup.

Homemade Basil Pesto
Homemade basil pesto is one of my favorite recipes to prepare in bulk during the summer. It takes just minutes to prepare, is extremely versatile and is ideal for freezing.  Since basil can be pricey during cooler months of the year, having frozen pesto on hand in the freezer is like having money in the bank.

Washing Basil for Pesto - The Lemon Bowl

Chances are, you are either growing basil in your backyard or live near a farmer who is selling it for pennies.  Making and freezing pesto is the perfect use for an abundance of fragrant fresh herbs.

  • Basil can be replaced spinach, parsley, arugula or cilantro.

Fresh lemon juice and zest brightens up the flavor and adds a great acidic balance to the olive oil, cheese and nuts. Toasting the pine nuts takes less than 10 minutes and provides a deep, rich flavor that you simply don’t get with raw pine nuts.

Pesto is packed with health benefits including heart-healthy mono-unsaturated fatty acids from the olive oil, iron from the leafy greens and vitamin C from the lemon. Added bonus? Iron helps boost the absorption of vitamin c so consuming them together is a win win.

  2. The whole lemon and zest was too much lemon for me so I added more garlic and pine nuts. Seemed to even it out a bit. Just putt in the freezer!

  3. I love Pesto, however my daughter has a nut allergy. Do you have any suggestions other than the ones you posted for swapping them out for something else?

  4. Great recipe but it is taking more then 2 hours to freeze. It may take longer to freeze then 2 hours. It tastes good,also I did not use the lemon juice or Zest it still turned out great. Al if you do not have a food processor you will need one a blender will not work. Love this it is worth all the work.

  5. I try not to use oil or consume oil of any kind in my food. Do I HAVE to use olive oil when making your pesto?

      • To make pesto w/o oil or cheese, for freezing: Just use the same proportions of fresh basil, garlic and lemon juice that you normally use for your pesto and pound, crush or blend in a food processor then freeze in half pint batches. When ready to use defrost, add cheese and oil and mix by hand and add to your recipe.

  6. My daughter has a severe nut allergy. I’m growing fresh basil & wanting to make pesto. Anything I can use instead of pine nuts? Or just completely omit the nuts & hopefully still taste awesome? Thanks!

  9. Liz,
    I’ve never thought to add lemon zest to my pesto–great idea. I make mine thicker (usually because I’ve got so many leaves vs cheese and nuts) and use a small disher or cookie scoop to freeze it on trays. The act of freezing bursts the cell walls, and the pesto is . . . well not runny, but let’s say liquid . . . when thawed. (I have a shortage of ice cube trays and don’t like to tie them up, so I tried it this way with success.)

    Thanks!

  10. I have never thought to freeze my pesto either! Also, due to a nut allergy in the fam, I use Pumpkin Seeds instead of Pine Nuts and it turns out great!

  16. Exactly what I plan to do this weekend. Our basil is going to seed so fast I’ve been plucking it like crazy; now to do something with all of that amazing abundance!

    I have been using toasted walnuts of late in pesto; as much as I love pine nuts; their $20/lb price tag needs some adjusting before it can regain it’s place as the favored kitchen nut!

    • I love the idea of toasting walnuts!! Pine nuts are so dang expensive but we buy them at Costco in bulk and freeze the bag. It lasts us about 3 months-6 months.

  19. I totally freeze pesto the same way!! This is how I made my kids baby food too. Ice cube trays are so versatile! ha ha. We have several basil plants growing in our backyard here in Vegas. My 5 year old will pick leaves and eat them like they are chips or something. Crazy kiddo

  20. ALL of these years I’ve been making basil pesto and never considered freezing it! What a brilliant tip, Liz. This is so useful, especially since I can’t get enough of the stuff year-round and homemade tastes SO much better than store bought.

    • Yes freezing it is the best!!! So much tastier than those tiny bottles for $6 at the grocery store. :)

  21. I laughed when I saw the title- this post couldn’t be more timely! We have a ton of basil in our garden. I made sunflower seed pesto a few days ago, and just harvested a whole colander full of basil this afternoon. It’s so nice to know that the basil cubes will be patiently waiting for me in the freezer come December :)

  26. Thanks for the reminder that I need to try this! I love, love, love pesto, but have never tried the freezer method. Now I just need to go load up on basil and other yummy greens :-)
