How to Freeze Fresh Basil with Olive Oil for Year‑Round Flavor
There’s nothing quite like the aroma of fresh basil picked straight from the garden. But if your plants are producing more than you can use right now, don’t let those fragrant leaves go to waste!
Freezing fresh basil with a light coat of olive oil is a quick and easy way to preserve that summer flavor for months to come. Plus, it’s a fantastic way to have basil ready for pasta, soups, sauces, or homemade pesto any time of year—no sad, wilted leaves in sight.
In this post, I’ll walk you through step‑by‑step how to pick, prep, and freeze basil so it stays bright, aromatic, and full of flavor.
Step 1: Pick Your Basil at Its Best
The best time to harvest basil is in the morning after the dew has dried but before the sun gets too hot. Look for vibrant green leaves with no signs of yellowing or damage. Use clean scissors or garden snips to cut stems just above a set of leaves—this encourages your plant to keep growing.
Step 2: Remove the Leaves from the Stems
Once you’ve brought your basil inside, gently strip the leaves from the stems. Discard any wilted or damaged leaves. This not only makes freezing easier but also saves you prep time later when you’re ready to cook. Gently rinse and dry the basil leaves. They need to be completely dry before moving to the next step.
Step 3: Lightly Coat with Olive Oil
Place the fresh basil leaves in a large mixing bowl. Drizzle lightly with olive oil—just enough to coat the leaves, not drench them. I use about 1 tablespoon of olive oil to 4 cups of basil leaves. The olive oil helps preserve the basil’s color and flavor while preventing the leaves from becoming brittle in the freezer or getting freezer burn.
Step 4: Bag and Label for Freezing
Transfer the oil‑coated basil into freezer‑safe bags. Gently press out any excess air to help prevent freezer burn. Label each bag with the date so you’ll know exactly how fresh your frozen basil is.
Step 5: Freeze Until You’re Ready to Use
Place your basil bags in the freezer, laying them flat for easy storage. Frozen basil will keep its flavor for up to 6 months—sometimes even longer! When you’re ready to use it, simply pull out the amount you need and add it directly to your dish—no thawing required.
Tips for Using Frozen Basil
- For sauces and soups: Add the frozen basil straight to your pot for a burst of fresh flavor.
- For pesto: Blend frozen basil with garlic, nuts, and Parmesan for a quick pesto anytime.
- For garnishes: Frozen basil works best in cooked dishes; for fresh garnishes, stick to freshly picked leaves.
Why This Works
Freezing basil with a touch of olive oil helps lock in its essential oils and aroma while protecting the delicate leaves from freezer burn. It’s a simple, no‑fuss method that keeps your basil tasting like it was just picked—long after your garden has gone to sleep for the season.
