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 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.

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…
