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 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.

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.
For a simple guide on washing and storing dark leafy greens (including basil!) be sure to check out my tips and video tutorial. It’s the best way to make fresh greens such as romaine, kale or Swiss chard last longer in the fridge.
If you don’t have every ingredient listed, get creative, and use what you have on hand with this easy swap-out guide:
- Basil can be replaced spinach, parsley, arugula or cilantro.
- Parmesan can be replaced with pecorino, romano, or Grana Padano cheese.
- Pine nuts can be replaced with walnuts, pistachios, or cashews.
Fresh lemon juice and zest will brighten 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 monounsaturated 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.

Olive oil prevents oxidation and slows the pesto from turning brown. I’ve never tried not using olive oil

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…
Liz DellaCroce
1/4 cup lemon juice and 1 teaspoon zest. :)

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.

Sounds great!!!!

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?
Liz DellaCroce
Great idea!

If frozen in an ice cube tray how much will it be defrosted?

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!
Liz DellaCroce
Ok I just re-did the calculations and I get 119 per two table spoons!
MAJ
You say it is 169 calories per serve but don’t say how many servings your recipe makes.
Liz DellaCroce

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!
Liz DellaCroce
