I love preparing homemade basil pesto in bulk during the summer. I can prepare the sauce in just minutes, and it’s also extremely versatile and ideal for freezing. When you’re in need of a quick lunch or dinner, you can take a cube of frozen pesto and have a sauced up pasta in minutes! It’s actually super simple, and I’ll show you how easy it is to make and freeze your own basil pesto.

Ingredients

  • Fresh basil: Whether from your own yard or the store or farmer’s market, it needs to be fresh!
  • Parmesan: Nutty and salty, it adds texture and flavor to the sauce.
  • Pine nuts: Instead of using raw pine nuts, I like to toast them to add a deep, rich flavor.
  • Garlic: Earthy, nutty, and somewhat spicy, it adds rich flavor to the pesto.
  • Lemon juice and zest: Brightens up the flavor while adding an acidic balance to the olive oil, cheese, and nuts.
  • Olive oil: Helps to evenly distrubute the ingredients as they blend and gives the pesto its spreadable consistency.

  1. Loved the recipe tasted great i put walnuts in mine. I want to ship some from Ma to Florida overnite should i send frozen or just as it was made

  2. Hi Liz, I saw where one of your commenters asked if you have to use olive oil in your pesto recipe. I have made it using avocado oil and it’s a great substitute. I personally missed the flavor of the olive oil, but for those who don’t like olive oil, I think they will like the avocado oil version. I have also used macadamia nuts and they were also a great substitute for the pine nuts.

  3. You gave purpose to all the basil growing in the tomato planter. First time ever making pesto and your recipe (substituted roasted cashews for pine nuts) è delizioso. Many thanks!

  4. This was my first time making basil pesto, and it was great! I did save pine nuts for garnish, and think I will also garnish with a touch of lemon zest when I have a fresh lemon in the fridge. Basil plant going crazy, another batch of leaves washed and spun to be processed tomorrow. Thank you for the recipe.

  5. Is there any way you could be more specific on the lemon juice and zest, they can vary in size so much? Right now I have a huge lemon, so I’m sure I don’t want to use the whole thing, but I’m not sure how much is the right amount…

  6. I use almonds & pre-grind them in a coffee bean grinder.
    I pour the pesto into ziplock freezer bags, lay them flat on a cookie sheet to freeze, then break off what I need &?reseal. Great space saver for the freezer & has lasted me all year.

  7. Delicious recipe but I went a little lighter on the lemon juice. I don’t have ice trays.. can I put it in mini muffin tin?

  8. Hi Liz! Thank you for this delicious recipe. I was calculating the pesto calories however as per my calculation 2 tbsp has 157 calories, 1.8 g carbs, 16.2 g fat (since you added 1 cup olive oil) and 2.3 g prot… correct me if I am wrong :) thanks again!

    1. If substituting the pine nuts for walnuts/cashews/pistachios:
      1) do I still toast them? How long and at what temperature?
      2)can I use a mix of the three kinds of nuts or should I stick with all of one kind?
      Thank you!

  9. 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!

  10. 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?

  11. 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.

      1. Do not wish to be a member of this site

        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.

  12. 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!
