7 Best Substitutes for Thai Chili (Ranked)

Running 50,000-100,000 SHU, Bird's Eye is the closest match you will find. The first time I grabbed a handful at an Asian grocery thinking they were Thai chilies, I realized the two are nearly interchangeable in most recipes. The peppery, forward-hitting heat of Bird's Eye lands in exactly the same register as Thai chili, with a similarly bright, clean finish.

Substitute 1:1 by count or weight. No adjustment needed.

Think of Thai Dragon as Thai chili's slightly sharper sibling. At 50,000-100,000 SHU, it hits the same heat range but with a more pointed, almost metallic brightness. The sharp Southeast Asian heat of Thai Dragon performs identically in stir-fries and nam prik, though the flavor edge is a touch more aggressive.

Use a 1:1 ratio, but taste as you go if your dish is heat-sensitive.

This Filipino variety tops out at 80,000-100,000 SHU, sitting at the higher end of the Thai chili range. The pungent, sharp character of Siling Labuyo makes it one of the better structural matches, though the heat is slightly more intense on average. It belongs to the same botanical family as Thai chili, which keeps flavor compatibility high.

Reduce to 3 peppers for every 4 Thai chilies called for, or match 1:1 if you want the extra heat.

Cabe Rawit is the Indonesian kitchen workhorse that lives in the same heat band: 50,000-100,000 SHU. The sharp, bright Indonesian heat of Cabe Rawit makes it a natural swap in any dish where Thai chili provides background fire rather than a starring role. It is widely used across sambal preparations, which tells you something about its versatility.

Substitute 1:1. Flavor is slightly less bright than Thai chili but close enough that most dishes won't notice.

Brazilian in origin, Malagueta clocks in at 60,000-100,000 SHU with a citrusy brightness that partially mirrors Thai chili's clean peppery profile. The citrus-edged heat from this South American staple won't replicate the exact flavor note, but the intensity lands correctly. It performs well in any context where Thai chili is used fresh or pickled.

Use 1:1 by count. Expect a slightly more citrus-forward finish.

The wild ancestor of many domesticated peppers, Chiltepin hits 50,000-100,000 SHU with a smoky, citrus-inflected heat that diverges from Thai chili's cleaner profile. That said, the smoky intensity of this ancient wild pepper still delivers the right heat level for most applications. These tiny round peppers belong to the regional pepper tradition of Mexico in spirit if not geography, representing a similarly deep food-culture connection.

Use 1 Chiltepin per 2 Thai chilies when cooking whole. If grinding, match by weight but expect a smokier result.

Rocoto is the outlier on this list, ranging 30,000-100,000 SHU with thicker flesh and a distinctly fruity, crisp character. The fruity, thick-walled Andean pepper known as Rocoto doesn't mimic Thai chili's texture or flavor at all, but it can deliver comparable heat in cooked applications where texture matters less. For sauces, pastes, or braises, it works reasonably well.

Use half the volume called for and taste before adding more. The lower end of Rocoto's range is significantly milder than Thai chili, so individual fruit heat varies considerably.

All seven of these sit within the high-heat category that Thai chili calls home, which means any of them can step in without fundamentally changing a dish's heat profile. The differences come down to flavor nuance: Bird's Eye and Thai Dragon stay truest to the source, while Chiltepin and Rocoto introduce new dimensions that work better in some contexts than others.
