Thai Basil: Uses, Flavor, Benefits & How to Grow It

Thai basil is a fragrant culinary herb recognized for its narrow green leaves, often-purple stems, and distinctive sweet, anise-like aroma. It is widely used in Southeast Asian cooking, where it adds a fresh, peppery flavor to curries, stir-fries, noodle dishes, and soups.

What Is Thai Basil?

Thai basil is a variety of basil known botanically as Ocimum basilicum var. thyrsiflora. It belongs to the mint family and is valued for its distinctive aroma and ability to retain much of its flavor during cooking.

Thai basil typically has pointed green leaves, sturdy stems that may appear purple, and purple-pink flower spikes. Its appearance and flavor distinguish it from the sweet basil commonly used in Italian cooking. Learn more about Thai basil.

The herb is commonly used in Thai dishes and also appears in Vietnamese and other Southeast Asian cuisines. It can be added to cooked dishes or served fresh as an aromatic garnish.

What Does Thai Basil Taste Like?

Thai basil has a sweet, peppery flavor with noticeable anise and licorice-like notes. Compared with Italian sweet basil, its aroma is often bolder and more spice-forward.

Its flavor works particularly well with ingredients such as garlic, chili, coconut milk, lime, soy sauce, noodles, vegetables, chicken, seafood, and tofu. The herb can be used during cooking, although adding it near the end often helps preserve its fresh aroma.

Thai Basil vs. Holy Basil: What Is the Difference?

Thai basil and holy basil are different herbs, although their names are sometimes confused in English-language recipes.

Feature	Thai Basil	Holy Basil
Botanical name	Ocimum basilicum var. thyrsiflora	Ocimum tenuiflorum
Flavor profile	Sweet, anise-like, and slightly peppery	Often described as peppery, clove-like, and more pungent
Common culinary role	Curries, noodle dishes, and stir-fries	Frequently associated with pad krapao-style dishes

Because the herbs have different flavor profiles, substituting one for the other can noticeably change a dish. When a recipe specifies Thai basil, use it if available; otherwise, choose a substitute based on the flavor you want.

Botanical and culinary references distinguish Thai basil from holy basil and lemon basil. Read a guide to the different basils.

Thai Basil Benefits and Nutrition

Thai basil is an aromatic herb that can contribute flavor to meals without requiring large quantities of added seasoning. Like other leafy herbs, it contains naturally occurring plant compounds.

However, evidence about compounds studied in laboratory settings should not be interpreted as proof that eating ordinary culinary amounts of Thai basil prevents or treats disease. Research findings about concentrated extracts or essential oils also cannot automatically be applied to fresh leaves.

For general wellness, Thai basil is best enjoyed as part of a varied, balanced eating pattern rather than as a treatment or supplement.

Where to Buy Thai Basil

If you are wondering where to buy Thai basil, check Asian grocery stores, specialty produce markets, farmers' markets, and supermarkets with a well-stocked fresh herb section. Availability varies by location and season.

You may also find Thai basil plants or seeds at garden centers and online gardening retailers. Search for the herb by its common name and, where possible, check the botanical name to avoid confusing it with sweet basil, holy basil, or lemon basil.

How to Choose Fresh Thai Basil

Look for leaves that appear fresh and relatively firm.
Avoid bunches with widespread blackening, sliminess, or decay.
Choose herbs with a fresh, aromatic smell.
Check labels carefully if you need a specific basil variety.

How to Grow Thai Basil

Thai basil can be grown in a garden or container when it has suitable warmth, sunlight, water, and soil conditions. Growing requirements depend on the local climate and growing environment.

Choose a sunny location: Select a spot with plenty of light and warmth.
Use well-drained soil: Choose soil or potting mix that allows excess water to drain away.
Water consistently: Keep the soil from drying out completely, but avoid leaving the roots in waterlogged soil.
Harvest regularly: Pick healthy leaves as needed and prune the plant to encourage bushier growth.
Monitor the plant: Check for pests, disease, and signs of stress, and adjust care as needed.

How to Store Thai Basil

Fresh Thai basil is delicate, so handle it gently and use it while the leaves are still fresh. Remove damaged leaves and keep the remaining bunch away from excess moisture.

Storage methods can vary depending on how fresh the herb is and how soon you plan to use it. If refrigerating it, protect the leaves from crushing and check them regularly for wilting or spoilage. For longer storage, freezing may be an option, although the leaves can lose some of their fresh texture.
