    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. 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!

    2. 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!

    3. 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!

      1. 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.

    4. 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

    5. 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 :)

      1. Hi thx for the recipe. I actually made pea pesto in the past so for those with treenut or even seed allergies this might work as well. For the person that asked about minimizing the oil I have also used vegetable broth or believe it or not tofu to make it creamy
