Why Freezing is the Best Way to Preserve Basil
Of all the ways to preserve fresh herbs freezing is ideal for delicate leafy basil. Air drying causes basil to lose its vivid green color, turning an unappetizing blackish hue. And flavors dissipate rapidly in the drying process.
Oil infusing or pesto making are great options too But these methods require more time and planning upfront
Freezing basil in ice cube trays offers the perfect solution. It’s incredibly easy. And frozen basil retains maximum color, aroma, and flavor. Here are some key advantages to freezing basil in ice cube trays:
- Maintains vibrant green color better than other methods
- Locks in sweet, aromatic basil flavor
- Convenient cube sizes for popping into recipes
- Allows basil to be frozen loose, not crushed or compressed
- Minimal preparation and hands-on time required
- Lets you freeze small batches as you harvest
Freezing also stops the enzymatic breakdown that causes basil to lose its signature flavor soon after harvest. In fact, some chefs prefer frozen basil to fresh!
Step-By-Step Instructions for Freezing Basil in Ice Cube Trays
Freezing basil in ice cube trays is simple and fast. You likely have all the supplies you need already. Follow these easy steps:
Harvest and Prep Basil for Freezing
-
Pick basil in the morning when leaves are most plump and filled with aromatic oils. Choose smaller leaves over larger, older ones.
-
Gently wash basil leaves if needed to remove grit. Dry thoroughly with paper towels or a salad spinner.
-
Remove basil leaves from tougher stems. Some tender stems can remain. Discard any flowers, bad spots, or very thick stems.
Portion and Pack Basil in Trays
-
Chop or tear basil leaves into smaller pieces to help them fit in cubes. Don’t bruise them.
-
Spoon chopped basil loosely into ice cube tray compartments, filling each about 3/4 full. Don’t crush or compress.
-
Pour just enough water over the basil in each cube to submerge it fully.
Freeze Basil Cubes
-
Cover tray and place in freezer overnight or until cubes are completely solid.
-
Pop out frozen cubes and transfer to freezer bags or airtight containers. Exclude as much air as possible.
-
Label bags with content and date. Use frozen cubes within 6-12 months for best flavor.
That’s really all there is to it! No blanching or special equipment required.
Handy Tips for Freezing Basil
Follow these tips to get the most out of your frozen basil cubes:
-
Use clean or distilled water instead of tap water to fill trays.
-
Freeze basil with stems attached to make long “logs” you can break off later.
-
Substitute olive oil or broth for water if desired based on recipe plans.
-
Freeze pesto in ice cube trays too. Thaw and stir before using.
-
Freeze other tender herbs like cilantro, mint, dill, and parsley this way too.
-
Blanching basil quickly before freezing can help maximize color retention.
Using Your Frozen Basil Cubes
Frozen basil ice cubes help you infuse dishes with fresh basil flavor any time of year. Their concentrated flavor and paste-like texture when thawed makes them uniquely useful in certain recipes.
Here are some of the many ways to use frozen basil cubes:
-
Soups – Drop a cube in simmering soups and stews near the end.
-
Sauces – Add to tomato-based sauces, salsa verde, pesto, chimichurri.
-
Dips – Blend into hummus, baba ghanoush, bean dips, and more.
-
Dressings – Whisk into salad dressing, marinades, and vinaigrettes.
-
Baked goods – Mix into focaccia dough, pesto bread, or herb muffins.
-
Rice/grains – Stir a cube into risotto, pilaf, couscous, or quinoa.
-
Eggs – Mix into scrambled eggs, frittatas, and omelets.
-
Smoothies – Blend into fruit or veggie smoothies.
Remember to thaw cubes first when a fresh texture is key, like for salad dressing. Otherwise, you can drop frozen cubes right into hot soups, stews, and sautés to thaw and incorporate.
Preserve Garden-Fresh Flavor Year-Round
Freezing fresh basil in ice cube trays is one of the easiest ways to capture and preserve basil’s quintessential flavor to savor for months after harvest season ends.
Give this simple method a try using basil from your garden or farmer’s market. Enjoy convenience of frozen basil cubes all winter to brighten up pastas, pizzas, soups, sauces, and more with the sweet flavor of summer any time you please.
Should I blanch basil before freezing?
Nope! After browsing many articles where folks did side-by-side tests of freezing blanched vs unblanched basil, I’ve come to conclusion that it’s not worth the effort (or risk). A quick blanch will help frozen basil retain a brighter green color, BUT just a moment too long in the hot water or steam can quickly result in mushy, overcooked basil. Unblanched basil retains a similar good flavor along with a better texture.
- Fresh basil
- Olive oil, water, or other culinary oil of choice
- Ice cube trays of choice. I like to freeze basil in silicone ice cube trays, which makes them incredibly easy to pop out and use! These flexible food-grade silicone trays create the perfectly petite frozen basil cubes (about 2 tablespoons per cube), or preserve larger servings with jumbo silicone ice cube trays like these.
- Resealable airtight freezer container for storage – such as a ziplock bag, reusable silicone food storage bags, or these durable freezer containers.
How to Use Frozen Basil Cubes
The ways to use frozen basil cubes are endless! Add them to any dish or meal that you’d enjoy fresh or dry basil in, including but not limited to:
- In homemade salad dressing
- Added to soup, stew, tomato sauce, curry, casseroles, and more (best to add towards the end, once things are almost finished cooking)
- In the pan with sautéed vegetables, stir fry, or scrambled eggs. I love the flavor it adds to our sautéed zucchini, cabbage, green beans, bok choy and other garden veggies.
- Toss a cube in the pot while cooking rice, quinoa, lentils, or dry beans
- To finish off cooked pasta, cold pasta salad, or potato salad (best if defrosted first)
Rather than fussing with defrosting, I usually add frozen basil cubes with olive oil straight from the freezer, allowing them to melt right into the dish.
If you freeze your basil cubes in water but don’t want water in your dish (or oil), simply place the basil cube in a small bowl or cup to defrost, and then strain off the water or oil once it melts – leaving just the basil bits to use.

FAQ
What is the best way to freeze fresh basil?
Does basil lose flavor when frozen?
Basil’s delicate volatile oils, responsible for its distinct aroma and flavor, are susceptible to breakdown during freezing. While freezing doesn’t completely eliminate these compounds, it can significantly reduce their potency and freshness, resulting in a less flavorful pesto compared to fresh basil.
How do you freeze fresh herbs in ice cube trays?
Fill an ice cube tray half full of water. Place herbs in each section of the tray—about 1 tablespoon in each. Push herbs under the water as much as possible. Place in the freezer.
