What to do with basil in the fall is a question every gardener faces as the first chill hits the air.
The answer isn’t just to say goodbye to your plants and wait for spring.
You actually have several fantastic options for what to do with basil in the fall, and most of them let you enjoy that fresh flavor for months to come.
In this post, we’ll walk through the best ways to handle your basil when autumn arrives, from harvesting and preserving to overwintering and saving seeds.
Let’s dive in and make sure none of that delicious basil goes to waste.
Why You Need a Plan for Basil in the Fall
Basil is incredibly tender and hates the cold, so knowing what to do with basil in the fall is crucial.
A single frost can turn your lush green leaves into black, mushy messes overnight.
That’s why the moment nighttime temperatures start dipping toward the 40s, you need to act fast.
The good news is that you don’t have to feel rushed or stressed because there are simple, effective strategies to preserve your harvest.
Whether you have a huge bumper crop or just a few pots on your windowsill, a plan for basil in the fall will keep your kitchen stocked.
1. Harvest Everything Before the First Frost
The very first thing to do with basil in the fall is to pick every remaining leaf and stem.
Don’t be shy about this, because once frost hits, the plant is done.
Harvest in the morning after the dew has dried for the best essential oil content and flavor.
Cut whole stems rather than individual leaves since this is faster and encourages a final flush if you get a warm week.
You’ll be amazed at how much basil you can collect from even a small plant.
2. Make Big Batches of Pesto
One of the most popular things to do with basil in the fall is turning it into pesto.
Pesto freezes beautifully, and you can make it in bulk using your food processor.
The classic recipe with pine nuts, garlic, parmesan, and olive oil is a no-brainer.
But don’t feel limited, you can also swap in walnuts, almonds, or even sunflower seeds.
Freeze the pesto in ice cube trays for perfect single-serving portions.
Once frozen, pop the cubes into a zip-top bag and you’ll have fresh pesto all winter long.
This is hands-down the tastiest answer to what to do with basil in the fall.
3. Dry Basil for Long-Term Storage
Drying is another classic choice for what to do with basil in the fall, especially if you have a massive harvest.
You can use a dehydrator, a low-temperature oven, or simply hang bunches upside down in a dry, dark place.
If you hang them, tie the stems together with twine and poke a small hole in a paper bag to place over the leaves.
This catches any falling leaves while allowing air circulation.
Once the leaves are completely crisp and crumbly, strip them from the stems and store in an airtight jar.
Dried basil won’t have quite the vibrant punch of fresh, but it’s perfect for soups and stews.
Creative Ways to Preserve Basil in the Fall
Beyond the usual suspects, there are other clever methods you might not have tried for basil in the fall.
These techniques lock in flavor and keep your autumn harvest exciting.
Let’s look at freezing whole leaves, infusing oils, and even making basil salt.
1. Freeze Whole Basil Leaves
Freezing whole leaves is one of the fastest things to do with basil in the fall.
Wash and thoroughly dry the leaves, then lay them in a single layer on a baking sheet.
Place the sheet in the freezer for a couple of hours until they’re frozen solid.
Transfer the frozen leaves to a container or bag, and they’ll stay separate instead of clumping.
You can drop these straight into sauces, smoothies, or stir-fries without thawing.
This method preserves the bright green color surprisingly well.
2. Infuse Olive Oil or Vinegar
Creating an infused oil is a gourmet answer to what to do with basil in the fall.
Gently warm olive oil and add fresh basil leaves, then let it steep for a few days in a cool place.
Alternatively, you can pack a clean bottle with leaves and pour good vinegar over them.
This makes a fantastic salad dressing base or a drizzle for roasted vegetables.
Just remember to keep herbal oils refrigerated and use them within a few weeks.
This is a lovely way to capture the essence of your garden in a different form.
3. Make Basil-Infused Butter or Salt
For something even more unique, consider basil-infused butter for your fall cooking.
Blend softened butter with finely chopped basil, then roll it into a log and chill.
Slice off rounds to melt over steak, corn, or crusty bread.
You can also make basil salt by whizzing salt and fresh leaves in a food processor until combined.
Spread the salt on a baking sheet to dry, then store in a jar.
These are creative, chef-approved things to do with basil in the fall.
Overwintering Basil Indoors
If you’re not ready to say goodbye, you can actually keep your basil alive through the winter.
The question of what to do with basil in the fall includes bringing it inside.
This takes a bit more effort, but it’s so rewarding to have fresh leaves in January.
Here’s how to give your basil the best shot at surviving indoors.
1. Dig Up and Pot Your Basil Plant
Before the first hard frost, dig up your healthiest basil plant from the garden.
Pot it in fresh, well-draining potting soil and water it thoroughly.
Place it in a bright, south-facing window or under a grow light.
Basil needs at least six hours of strong light daily to thrive indoors.
You can also root cuttings in water and transfer them to soil for a new generation.
This is a great way to extend what to do with basil in the fall.
2. Take Cuttings for a Windowsill Garden
Instead of bringing the whole plant, you can take several cuttings to root.
Cut four-inch stems right below a leaf node and strip off the lower leaves.
Place the cuttings in a glass of water on a sunny windowsill, changing the water every few days.
Roots will appear in about a week or two.
Once roots are an inch long, plant them in small pots with potting mix.
Keeping basil indoors is one of the most satisfying things to do with basil in the fall.
You’ll have a steady supply for cooking, and it smells incredible.
Saving Seeds from Your Fall Basil
Don’t forget about the future, saving seeds is a smart thing to do with basil in the fall.
If you let a couple of plants flower and go to seed, you’ll have plenty for next year.
Wait until the flower spikes turn brown and dry on the plant.
Then, cut the spikes and place them in a paper bag to finish drying indoors.
Once fully dry, shake the bag to release the tiny black seeds.
Store the seeds in a labeled envelope in a cool, dark, and dry place.
This is an economical and rewarding way to continue your basil journey.
