Why Basil Struggles in Winter and How to Overcome It
Basil is a warm-weather annual, which means it naturally wants to die when temperatures drop below 50°F.
What to do with basil in the winter starts with understanding that it’s not a cold-hardy herb at all.
But that doesn’t mean you’re out of luck, because a few smart moves can keep the party going indoors.
Let’s break down the main challenges and how to solve them so your basil doesn’t become a sad, wilted memory.
1. Bring Potted Basil Indoors Before Frost
If you have basil in a container, the easiest thing to do with basil in the winter is to relocate it inside.
Before the first frost hits, move the pot to a sunny windowsill that gets at least six hours of direct light.
Basil loves warmth, so keep it away from drafty windows and cold air vents that can shock the plant.
Check for pests first, because indoor basil can attract aphids and spider mites if you’re not careful.
Give it a good watering, but don’t overdo it, as soggy soil leads to root rot in the cooler months.
Your basil might slow down its growth, but it will survive and keep producing leaves for you to snip.
2. Use a Grow Light to Mimic Summer Sun
Even a south-facing window might not provide enough light in the dark winter months.
What to do with basil in the winter often involves investing in a simple LED grow light to supplement natural sunshine.
Place the light about six inches above the plant and leave it on for 12 to 14 hours a day.
This trick keeps photosynthesis going, so your basil doesn’t become leggy and flavorless.
You’ll notice the leaves stay lush and green, almost like it’s still July.
And it’s a cheap fix that pays off in fresh basil all winter long.
3. Take Cuttings to Root New Plants
One of the smartest things to do with basil in the winter is to propagate cuttings from your outdoor plant before it dies.
Snip a four-inch stem just below a leaf node, then remove the lower leaves.
Place the cutting in a glass of water on a sunny windowsill, and roots will form in about a week.
Once the roots are an inch long, transplant the cutting into a small pot with fresh soil.
This gives you a constant supply of young basil plants that thrive indoors.
Best of all, you can keep doing this all winter for an endless harvest.
Freezing Basil: The Best Way to Preserve Fresh Flavor
Freezing is hands-down the most popular answer when wondering what to do with basil in the winter.
Unlike drying, freezing locks in that bright, peppery flavor and vibrant green color almost perfectly.
You won’t get crisp leaves for salads, but it’s ideal for cooked dishes, sauces, and soups.
Let’s look at the best freezing methods so you can grab basil anytime you need it.
1. Freeze Whole Leaves on a Baking Sheet
Wash and thoroughly dry your basil leaves, then lay them in a single layer on a parchment-lined baking sheet.
Pop the sheet in the freezer for a couple of hours until the leaves are frozen solid.
Transfer the frozen leaves to a zip-top bag or airtight container, and squeeze out as much air as possible.
This method keeps individual leaves separate, so you can easily grab a few without thawing the whole batch.
Frozen basil leaves keep their quality for up to six months, though they’re still safe to eat longer.
Just remember to add them straight to hot dishes, no need to thaw first.
2. Make Basil Ice Cubes for Easy Portions
Another fantastic thing to do with basil in the winter is to chop the leaves and freeze them in ice cube trays.
Fill each compartment with chopped basil, then top it off with water, olive oil, or broth.
Freeze overnight, then pop the cubes out and store them in a freezer bag.
When you’re making pasta, curry, or stew, just toss in a cube or two.
The liquid melts into your dish, releasing all that herby goodness evenly.
You can even mix garlic or lemon zest into the cubes for extra flavor.
3. Blend Basil into a Pesto Puree
If you have a large harvest, making pesto is a delicious answer to what to do with basil in the winter.
Blend basil leaves with garlic, pine nuts, parmesan, and olive oil into a thick paste.
Spoon the pesto into ice cube trays or small jars, then freeze it for later use.
Thaw a cube in the fridge overnight, and you have instant sauce for pasta or a spread for sandwiches.
You can also skip the cheese and nuts, freezing just basil and oil for a versatile base.
That way, you add cheese fresh when you’re ready to eat, keeping things flexible.
Drying Basil for Long-Term Storage
Drying is a classic method, and it’s one of the simplest answers to what to do with basil in the winter.
The trade-off is that dried basil has a milder, slightly different flavor than fresh, but it’s still wonderful for seasoning.
Here are the best ways to dry basil so it stores well for months.
1. Air Dry Basil Bunches
Tie a few basil stems together with twine and hang them upside down in a dry, dark, well-ventilated area.
It takes about one to two weeks for the leaves to become completely dry and crumbly.
Avoid hanging them in direct sunlight, as that can bleach the color and reduce flavor.
Once dry, strip the leaves from the stems and crush them into a jar with a tight lid.
Keep the jar in a cool, dark pantry, and your dried basil will last up to a year.
This is a perfect no-power method for those who love the old-school approach.
2. Use a Dehydrator or Oven
If you’re short on time, a food dehydrator is a quick way to dry basil in just a few hours.
Set the dehydrator to about 95°F and lay the clean leaves on the trays in a single layer.
You can also use your oven on the lowest setting, around 170°F, with the door slightly ajar.
Check every 30 minutes until the leaves crumble between your fingers.
Cool the dried leaves completely before storing to prevent condensation and mold.
Store in an airtight glass jar, and you’ve solved what to do with basil in the winter with ease.
Creative Ways to Use Up Your Winter Basil
Beyond freezing and drying, there are plenty of delicious and creative options for what to do with basil in the winter.
You can infuse oils, make flavored butters, or even brew basil tea for a soothing hot drink.
Let’s explore these gourmet tricks that elevate your cooking and reduce waste.
1. Infuse Olive Oil with Basil
Basil-infused olive oil is a chef’s secret weapon and a fantastic thing to do with basil in the winter.
Gently warm a cup of olive oil and add a handful of fresh, clean basil leaves.
Let them steep for about 30 minutes over low heat, never letting the oil simmer.
Strain the oil into a sterilized glass bottle and store it in the fridge.
Drizzle this oil over salads, roasted veggies, or crusty bread for instant flavor.
Use it within a week or two for the best taste and safety.
2. Make Basil Butter for Pan-Seared Meals
Mix softened butter with finely chopped basil, a pinch of salt, and a squeeze of lemon juice.
Roll the butter into a log using plastic wrap, then freeze it until solid.
Slice off a pat whenever you cook steak, fish, or pasta to melt over the top.
This is a luxurious way to use up fresh basil you’ve been overwintering.
The butter keeps for months, giving you a taste of summer in every meal.
It’s one of the easiest answers to what to do with basil in the winter that feels fancy.
3. Brew Basil Tea or Lemonade
Basil isn’t just for savory food, it makes a surprisingly refreshing tea or lemonade.
Steep a handful of fresh basil leaves in hot water for five minutes, then add honey and lemon.
For a cold drink, muddle basil leaves with sugar and lime, then add sparkling water.
This is a wonderful way to enjoy your fresh winter basil on a chilly afternoon.
The aromatic notes are calming and slightly sweet, perfect for easing a sore throat.
So if you’re wondering what to do with basil in the winter, don’t forget the beverage possibilities.
