You can make basil cubes by chopping fresh basil, packing it into ice cube trays, and freezing it with water, oil, or stock.
It’s honestly one of the easiest kitchen hacks you’ll ever try, and it saves you from tossing out sad, wilted herbs ever again.
If you’ve ever stared at a bunch of basil and wondered how to make basil cubes that actually taste fresh months later, you’re in the right place.
In this post, we’ll walk through the best methods for making basil cubes, what liquids to use, and how to store them so they stay vibrant and flavorful.
Let’s dive right in and get your freezer stocked with herbal gold.
Why You Should Make Basil Cubes
Basil cubes are a game-changer for anyone who loves cooking with fresh herbs but hates waste.
When you make basil cubes, you’re locking in that bright, peppery flavor at its peak freshness.
Fresh basil wilts within days in the fridge, but frozen basil cubes can last for six months or more.
Plus, having a few basil cubes ready to go means you can add instant flavor to soups, sauces, pastas, and marinades without any prep work.
So if you’re wondering how to make basil cubes that fit your cooking style, the key is choosing the right freezing liquid.
1. Basil Cubes With Water: The Neutral Option
The simplest way to make basil cubes is to freeze them with plain water.
This method works best if you plan to drop the cubes into simmering dishes like stews or broths.
Water keeps the basil pure and doesn’t add any extra fat or flavor to your meal.
However, water-based basil cubes can get a bit icy, so they’re not ideal for fresh salads or garnishes.
Still, for cooking purposes, water is a perfectly good choice when you make basil cubes this way.
2. Basil Cubes With Olive Oil: The Flavor Booster
If you want to know how to make basil cubes that double as a cooking base, olive oil is your best friend.
Olive oil freezes beautifully, and it helps preserve the bright green color of the basil.
More importantly, the oil blends with the basil to create a ready-to-use paste that’s perfect for sautéing.
Just pop a basil cube straight into a hot pan, and you’ve got an instant flavor foundation for pasta or risotto.
This is my favorite way to make basil cubes because it streamlines dinner prep so much.
3. Basil Cubes With Stock: The Savory Shortcut
Another smart way to make basil cubes is to freeze them with vegetable or chicken stock.
This adds another layer of savory depth to your herbs, which is amazing for soups and braises.
Stock-based basil cubes are like little flavor bombs that melt right into whatever you’re cooking.
Just keep in mind that stock adds salt, so adjust your seasoning when you use these cubes.
If you love how to make basil cubes with extra umami, this is the way to go.
Step-By-Step: How To Make Basil Cubes From Scratch
Now that you know the liquids, let’s get into the actual process of how to make basil cubes from start to finish.
It only takes about 15 minutes of active time, and the rest is just waiting for the freezer to work its magic.
Here’s exactly what you need to do.
Step 1: Wash And Dry The Basil Thoroughly
Start by giving your fresh basil a good rinse under cold water to remove any dirt or tiny bugs.
Then, dry the leaves completely using a salad spinner or by patting them gently with paper towels.
Moisture is your enemy here because excess water on the leaves can cause them to turn mushy and dark.
Take your time with this step because dry leaves are the secret to making basil cubes that stay green and firm.
Step 2: Chop Or Pulse The Basil Leaves
Next, remove the leaves from the stems and give them a rough chop with a sharp knife.
Alternatively, you can pulse them a few times in a food processor to get a finer, more consistent texture.
You don’t want a paste yet, just small pieces that are easy to pack into the slots of your ice cube tray.
This step is crucial when you make basil cubes because it prevents large clumps and ensures even freezing.
Step 3: Pack The Basil Into Ice Cube Trays
Spoon the chopped basil into each compartment of a standard or silicone ice cube tray.
Fill them about halfway full to leave room for the liquid you’ll add next.
Gently press the basil down with your spoon so it’s compact and no big air pockets remain.
If you’re using silicone trays, this step is even easier since the cubes pop out effortlessly later.
Step 4: Pour Your Liquid Over The Basil
Now, slowly pour your chosen liquid (water, olive oil, or stock) over the basil in each compartment.
Leave a little gap at the top because liquids expand when they freeze, and you don’t want overflow.
If you’re using olive oil, don’t worry if it looks like a lot, since it will slightly solidify and hold the basil together.
Once your trays are filled, move on to the next step to learn the best freezing technique.
Step 5: Freeze And Transfer For Long-Term Storage
Place the trays on a flat surface in your freezer and let them freeze for at least 4 to 6 hours, or preferably overnight.
After they’re solid, pop the basil cubes out of the tray and store them in a zip-top freezer bag or airtight container.
Label the bag with the date and what liquid you used, so you don’t mix up your basil cubes later.
This is the final step in how to make basil cubes that last for months without losing their punch.
Tips For Getting The Most Out Of Your Basil Cubes
Once you know how to make basil cubes, you’ll want to use them wisely so they don’t go to waste.
Here are a few pro tips to elevate your basil cube game.
1. Use Fresh Basil For The Best Flavor
The quality of your basil cubes depends entirely on the quality of your fresh basil.
Choose leaves that are deep green, fragrant, and free from spots or wilting.
Homegrown or farmers’ market basil is often far more aromatic than the store-bought bunches.
So if you’re serious about how to make basil cubes well, start with the freshest herbs you can find.
2. Don’t Thaw Before Cooking
The beauty of basil cubes is that you can toss them straight from the freezer into a hot pan or pot.
Thawing them first can make them watery and cause the basil to turn brown.
So when you make basil cubes, just grab what you need and drop them in while frozen.
The heat will melt the liquid and release the basil’s aroma almost instantly.
3. Freeze In Small Batches
Try to make basil cubes in small batches, especially if your basil plants produce a lot at once.
This way, you can use them up within a few months instead of letting them sit for half a year.
Small batches also allow you to experiment with different liquids without committing a huge amount of basil.
And if you’re still learning how to make basil cubes, smaller batches are easier to practice with.
4. Blend Basil With Garlic For A Pesto Base
If you really want to level up, add a clove of garlic or a pinch of salt to the basil before freezing.
This turns your basil cubes into a ready-made pesto foundation that only needs cheese and nuts.
It’s a clever twist on how to make basil cubes that gives you an instant sauce base.
Just remember that garlic’s flavor intensifies in the freezer, so use a little less than you think.
So, How To Make Basil Cubes? It’s Simpler Than You Think
You can make basil cubes with just three ingredients: fresh basil, your favorite liquid, and an ice cube tray.
So if you’ve been wondering how to make basil cubes all along, the answer is that simple.
Whether you choose water for neutral cooking, olive oil for rich flavor, or stock for savory dishes, the process stays the same.
The key is to dry your basil well, pack the trays tightly, and freeze them solid before transferring.
In this post, we’ve covered why basil cubes are so handy, the different liquids you can use, and the exact steps to get it right.
Now you can preserve that beautiful summer basil and enjoy it all year round without any hassle.
