It is known for its anti-inflammatory properties and high antioxidant levels. Preserving basil allows you to capture its distinct flavor, ensuring that you can enjoy it even when it is out of season.
Key Benefits of Preserving Basil:
- Enjoying basil’s fresh flavor all year round
- Reducing food waste by utilizing excess herbs

Essential Tips for Harvesting Basil
Before we get into the preservation methods, it’s crucial to know how to harvest basil properly to ensure its optimum flavor and longevity. Here are some tips for harvesting basil:
1. Timing is Key
Harvest basil early in the morning when the leaves are firm and full of moisture. This is when the flavor is at its peak.
2. Use Clean Tools
Always use clean, sharp scissors or pruning shears to avoid damaging the plant. Cut no more than one-third of the plant at a single time to promote healthy regrowth.
3. Remove Flower Buds
If you notice flowers starting to form, pinch them off. Once basil flowers, it can change the flavor of the leaves, making them bitter.
Methods of Preserving Basil
Preserving basil can be accomplished through several different methods. Each method has its own set of advantages, and often, the best approach is to use a combination of techniques.
1. Freezing Basil
Freezing basil is one of the most popular and straightforward preservation methods. This method locks in the fresh flavor and aroma of basil effectively.
How to Freeze Basil: Step-by-Step
Option A: Freezing Whole Leaves
1. Wash and Dry: Rinse the basil leaves under cool water and gently dry them using a salad spinner or paper towels.
2. Lay Flat: Spread the leaves in a single layer on a baking sheet and place them in the freezer.
3. Transfer to Bags: Once frozen solid, transfer the leaves to a resealable freezer bag. Make sure to remove as much air as possible before sealing.
4. Label and Store: Don’t forget to label the bag with the date to track freshness.
Option B: Basil Ice Cubes
1. Chop and Prepare: Finely chop fresh basil leaves and place them in ice cube trays.
2. Add Olive Oil: Fill each cube compartment with olive oil, covering the chopped basil entirely.
3. Freeze: Once frozen, transfer the basil cubes to a freezer bag. They can be used directly in cooking, adding flavor to soups, sauces, and sautéed dishes.
2. Drying Basil
Drying is another traditional method of basil preservation. While it won’t capture the full flavor of fresh basil, it is effective for long-term storage.
How to Dry Basil: Step-by-Step
Option A: Air Drying
1. Harvest and Bundle: Tie together around 5-10 stems with twine or rubber bands.
2. Hang: Place the bundle in a warm, dark area with good air circulation. A kitchen cupboard works well for this.

2. Spread Leaves: Place washed basil leaves on a baking sheet lined with parchment paper. Spread them out evenly.
3. Bake: Place the sheet in the oven for about 1-2 hours, checking frequently to avoid burning.
4. Cool and Store: Once dry, let the leaves cool completely before crumbling them into jars. Store in a cool, dark place.
3. Making Basil Pesto
Basil pesto is a wonderfully versatile way to preserve basil while creating a delicious product that can be used in various dishes.

Basil-infused oil can impart a lovely flavor to dressings or marinades. Simply combine basil with olive oil in a jar and let it steep for at least a week.
2. Basil Salt
By combining salt and dried basil, you can create a flavorful seasoning. Simply mix equal parts salt with dried basil and store in an airtight container.
Storing Your Preserved Basil
Once you have preserved your basil using any of the above methods, it’s vital to store it properly.

What is the best time to harvest basil for preservation?
The best time to harvest basil for preservation is in the morning after the dew has evaporated but before the sun is too hot. This time of day ensures that the leaves are at their freshest, retaining maximum flavor and aroma. It is advisable to harvest basil before it starts to flower, as flowering can cause the leaves to become bitter.
When you see the plant starting to form buds, it’s a good indication that you should take a cutting. Regular harvesting encourages bushier growth and more prolific leaf production, allowing you to gather ample amounts of basil for preserving throughout the growing season.
What are the best methods for preserving basil?
There are several effective methods for preserving basil, including drying, freezing, and making pesto. Drying basil is a classic preservation technique, which involves hanging the stems upside down in a cool, dark, and dry place. Once the leaves are crispy, you can store them in airtight containers for long-term use.
Freezing basil is another popular method, especially if you want to retain the fresh flavor. You can either freeze whole leaves in ice cube trays with water or oil or chop the leaves and mix them with oil before freezing. This method gives you a convenient way to add basil to your cooking all year round.
How should I prepare basil for freezing?
To prepare basil for freezing, start by washing the leaves thoroughly under cool running water to remove any dirt or pests. Pat them dry with a clean towel or use a salad spinner to remove excess moisture. It’s important to ensure the leaves are dry before freezing to prevent ice crystals from forming, which could affect texture and flavor.
Next, you can choose to freeze the leaves whole or chop them into smaller pieces. If you prefer, combine the basil with olive oil in a blender and then pour the mixture into ice cube trays. Once frozen, you can transfer the cubes to a freezer bag, allowing easy access to the basil whenever you need it.
Can I preserve basil by making pesto?
Yes, making pesto is an excellent way to preserve basil while creating a delicious condiment or sauce. Pesto typically combines fresh basil with garlic, pine nuts, Parmesan cheese, and olive oil. This mixture not only captures the fresh flavor of basil but also provides a versatile addition to pasta, sandwiches, and salads.
To preserve pesto, prepare a batch using your garden-fresh basil, and then store it in airtight containers or jars. Pesto can be refrigerated for a week or frozen for longer storage. If freezing, consider adding a thin layer of olive oil on top before sealing to help maintain its vibrant color and fresh taste.
How can I dry basil properly?
Drying basil can be done through several methods, including air drying, using an oven, or a dehydrator. For air drying, gather a bunch of basil stems, tie them with string, and hang them upside down in a well-ventilated area away from sunlight. This natural method takes about one to two weeks, depending on humidity levels.
If you’re short on time, the oven method provides a quicker solution. Preheat the oven to the lowest setting, spread the leaves on a baking sheet, and leave them for a couple of hours until they are completely dried. Keep the oven door slightly ajar to prevent overheating. Once dried, store the basil leaves in an airtight container, away from light and moisture.
What are the signs that basil is going bad?
Basil can go bad if not preserved or stored correctly, and there are several signs to look out for. Fresh basil leaves will show discoloration, turning dark or brown, and may begin to wilt or become slimy. If you notice these changes, the basil is no longer suitable for use and should be discarded.
Additionally, dried basil can also spoil. If you notice an off-putting smell or if the leaves have lost their vibrant color and aroma, they may have lost their potency. Always store dried basil in a cool, dark place, and check for quality before use to ensure optimal flavor in your dishes.
Can I use wilted basil for preservation?
While fresh, vibrant basil is ideal for preservation, slightly wilted basil can still be used, but with caution. If the leaves are merely limp but otherwise healthy, you can hydrate them by placing them in a glass of water for a few hours, which may revive their crispness. If wilted leaves show signs of browning or decay, it’s best to discard them.
However, keep in mind that the flavor and aroma of wilted leaves may not be as intense as fresh ones. Therefore, for best results in preservation methods like drying or making pesto, use only the best quality leaves. Storing wilted basil is generally not advisable as it may compromise your end product.
How can I maximize the shelf life of preserved basil?
To maximize the shelf life of preserved basil, proper storage is key. For dried basil, ensure it is kept in an airtight container in a cool, dark place, away from direct sunlight and moisture. This helps maintain its flavor and prevents spoilage. Avoid opening the container frequently, as exposure to air can degrade its quality.
If you choose to freeze basil, use high-quality freezer bags or airtight containers. Removing as much air as possible helps prevent freezer burn, allowing the basil to maintain its flavor. Label and date your containers to keep track of storage time, as frozen basil can last up to six months but is best when used within three months for maximum freshness.
