Perilla Leaf Substitute: Why Vietnamese Tía Tô Isn’t the Korean Kind

The right substitute here depends on which “perilla leaf” a recipe actually means, since English-language sources use that name loosely across three different regional herbs. Here’s what covers the common Korean use case, what actually works for Vietnamese tía tô, and why they’re not quite the same swap.

Thai Basil and Mint Together Get You Closest

Tía tô’s flavor sits in an unusual middle ground — part basil, part mint, with a faint anise edge and a slightly musky finish that neither herb has on its own. Combining Thai basil and fresh mint in roughly equal parts covers more of that range than either herb alone. Use it the same way you’d use tía tô: torn by hand and added at the table or right at the end of cooking, not simmered in, since both substitute herbs lose their brightness fast under heat. This combination works well on a herb plate, where tía tô is usually eaten raw alongside other fresh herbs rather than cooked into the dish itself.

Thai Basil Alone Works, at Half the Amount

If mint isn’t available either, Thai basil by itself is a reasonable single-herb stand-in — it already carries a mild anise note that gets partway to tía tô’s flavor. Start with about half the amount a recipe calls for in tía tô, then add more to taste, since Thai basil’s flavor is more concentrated in a single direction and can overwhelm a dish if used at a full 1:1 swap. This is the more convenient option when Thai basil is already on hand for a dish that calls for it separately, which is common in Vietnamese cooking.

Sweet Basil Plus Cilantro, a Rougher Approximation

Sweet (Italian) basil alone misses tía tô’s mint and anise character almost entirely, reading as flatter and more one-dimensional. Mixing in a small amount of fresh cilantro helps round out the gap, even though cilantro’s flavor is genuinely different from tía tô’s. This combination is more of a last resort than a real match — it fills the herb plate visually, but anyone familiar with tía tô’s actual flavor will notice the difference.

For Wraps Specifically, Size Matters More Than Flavor

When a recipe calls for whole perilla leaves as a wrapper — the way Korean cooking uses kkaennip for ssam, wrapping grilled meat or rice directly in the leaf — flavor-matching takes a back seat to finding something the right size and sturdiness. Grape leaves (briny, and usually brined) or butter lettuce leaves are the common stand-ins here, chosen for their ability to hold a filling rather than for tasting anything like perilla. This use case doesn’t really come up in Vietnamese cooking, where tía tô is almost always torn into smaller pieces on a herb plate rather than used as an intact wrapper.

Perilla Leaf Isn’t One Herb — Tía Tô vs Korean Perilla

This is where most substitute guides written for a Western audience miss the point for anyone cooking Vietnamese food. Botanically, tía tô and Japanese shiso are the same variety, Perilla frutescens var. crispa — the milder of the plant’s known varieties, with leaves that shift from green to deep purple depending on the plant and often show both colors on a single leaf, green on top and purple underneath, with visibly jagged edges. Korean perilla, called kkaennip or deulkkae, is a separate, more strongly scented variety, Perilla frutescens var. frutescens, grown as much for its seeds — pressed into perilla oil or ground into powder — as for the leaf itself.

That difference in intensity is also a difference in how each one is used. Kkaennip is typically served as a whole, sturdy wrap leaf, standing up to being layered around meat and rice. Tía tô, milder and more delicate, is torn by hand onto a communal herb plate, mixed in with mint, Thai basil, and other fresh herbs rather than eaten as its own wrapper. It’s part of the herb plate served alongside bún bò Huế, bún chả, and bánh xèo, and it also gets stirred directly into dishes like cháo and fish-based soups, where Vietnamese cooks have long used it to help cut the fishy smell in snail and fish dishes — a use that has less to do with formal cuisine and more with what generations of home cooks have simply found works.

Where the Substitutes Fall Short

None of the swaps above fully replicate tía tô’s specific combination of mint, basil, and anise in one leaf. On a Vietnamese herb plate crowded with other fresh herbs, lime, and chili, a close substitute like Thai basil and mint mostly holds its own. In a dish where tía tô is the main flavor rather than one herb among several — like a cháo where it’s stirred in at the very end — the gap is more noticeable, and it’s worth knowing that going in. If Thai basil itself is also missing from the herb drawer, that shortage tends to overlap with this one more often than not.

A friend visiting from the US once asked why I kept calling the wrap leaves at a Korean barbecue place “perilla” when I’d never used that word for the tía tô on my own dinner table back home. I hadn’t actually connected the two before that — they’re such different textures and different jobs on a plate that it never occurred to me they were close relatives. She tried tía tô for the first time a week later at a bún bò Huế stall near Đông Ba market and said it tasted nothing like what she’d had wrapped around bulgogi, which is more or less exactly right.
