What Is a Thai Red Chili Anyway?

The Thai red chili, also known as bird’s eye chili, packs a serious punch. Ranking between 50,000 to 100,000 on the Scoville scale, it’s significantly hotter than jalapeños but not quite ghost pepper territory. These small, slender peppers are usually used fresh, dried, or ground into pastes that give dishes like green curry, tom kha gai, and pad see ew their signature fiery kick.

But here's the catch — they aren’t always easy to find outside of specialty stores or Asian markets. That’s where knowing your alternatives becomes essential. Let’s take a look at why substitution might be necessary and which peppers can step in when the heat runs out.

Why Substitute?

There are plenty of reasons you might reach for a Thai red chili substitute:

• Availability: Not every grocery store stocks fresh or dried Thai chilies.
• Heat Level: Some cooks find Thai red chilies too intense and prefer a milder alternative.
• Taste Preferences: Sometimes you want a similar spice level but a different flavor profile.
• Substitution in Cooking: Certain recipes require specific forms of chili (e.g., paste vs. fresh), so you may need a substitute that matches the format.

Thankfully, there’s no shortage of flavorful contenders ready to take center stage. Let’s dive into our top seven picks!

Top 7 Thai Red Chili Substitutes

1. Serrano Pepper

• Scoville Units: 10,000–23,000
• Flavor Profile: Bright, grassy, slightly fruity
• Best For: Fresh use in salsas, salads, and hot sauces

Serranos are a great go-to because they handle heat well — literally. They retain flavor even when cooked and are often used in Mexican and Thai fusion dishes. They’re spicier than jalapeños but still more manageable than Thai red chilies.

2. Cayenne Pepper

• Scoville Units: 30,000–50,000
• Flavor Profile: Earthy, sharp, mildly smoky
• Best For: Ground into powder or used in dry rubs and curries

If you're working with dried chilies or spice blends, cayenne makes an excellent substitute. It’s commonly found in powdered form, making it perfect for Thai-inspired marinades and stir-fry sauces.

3. Fresno Chili

• Scoville Units: 2,500–10,000
• Flavor Profile: Smoky, sweet, slightly citrusy
• Best For: Fresh slicing into soups, noodles, or rice bowls

Fresno chilies are often mistaken for red jalapeños but offer a bit more heat and a unique sweetness that pairs nicely with coconut-based curries or grilled meats.

4. Arbol Chili

• Scoville Units: 15,000–65,000
• Flavor Profile: Nutty, woody, sharp aftertaste
• Best For: Dried chilies for oil infusions, salsas, or broths

Arbol chilies are thin, red, and seriously spicy. Perfect for adding depth to oil or broth-based Thai dishes. Use them sparingly unless you're chasing extreme heat!

5. Habanero (Use With Caution)

• Scoville Units: 100,000–350,000
• Flavor Profile: Tropical, floral, very hot
• Best For: Experimental cooks and heat lovers

Habaneros are not for the faint of heart. But if you're looking for extreme spice and a unique flavor profile, a tiny sliver can replace a whole Thai red chili. Just make sure to wear gloves!

6. Jalapeño (For Milder Heat)

• Scoville Units: 2,500–8,000
• Flavor Profile: Crisp, mild, slightly vegetal
• Best For: Beginners or milder versions of Thai dishes

Jalapeños are much milder, but they work well when you want to keep things approachable. Remove the seeds for even less heat or roast them for added smokiness.

7. Ghost Pepper (Not Recommended Unless You’re Brave)

• Scoville Units: 855,000–1,041,427
• Flavor Profile: Fruity, earthy, extremely hot
• Best For: Daring chefs or contests

This one is included more for dramatic effect. While technically a substitute in terms of heat intensity, it’s overkill for most traditional uses. A dash of ghost pepper powder could stand in for a full Thai red chili — but proceed with caution!

Buying Guide: How to Choose the Right Substitute

Choosing the right Thai red chili substitute depends on several factors: heat tolerance, flavor preference, cooking method, and availability. Here’s how to shop smart:

1. Determine Your Desired Heat Level

• Low Heat: Jalapeño, Fresno chili
• Moderate Heat: Serrano, Cayenne
• High Heat: Arbol, Habanero
• Extreme Heat: Ghost Pepper (with reservations)

2. Match the Format

Are you using fresh chilies? Dried ones? Powder? Make sure the substitute matches the form you need.

• Fresh Chilies: Serrano, Jalapeño, Fresno
• Dried Chilies: Arbol, Cayenne flakes
• Ground/Powdered: Cayenne powder, ghost pepper powder

3. Consider Flavor Compatibility

Some peppers add sweetness, others smoke or citrus notes. Think about how the flavor will interact with your dish:

• Sweet & Mild: Fresno chili
• Grassy & Sharp: Serrano
• Smoky & Woody: Arbol
• Tropical & Floral: Habanero

4. Know Where to Buy

• Fresh Chilies: Most supermarkets carry jalapeños and serranos; local ethnic markets may have Fresnos or arbol chilies.
• Dried Chilies: Specialty spice shops or online retailers like Amazon or Penzeys Spices.
• Ground Chilies: Available in most spice sections; look for pure powders without fillers.

5. Try Pre-Made Alternatives

If you’re short on time or ingredients, pre-made chili pastes can save the day:

• Rooster Brand Sriracha: Great for general spice boost.
• Lee Kum Kee Chili Garlic Sauce: Balanced flavor and heat.
• Asian Kitchen by Shuang Hui Chili Paste: Closer to traditional Thai profiles.

Frequently Asked Questions

Can I use bell peppers as a substitute?

Nope — bell peppers are sweet and won’t provide any heat. However, they can balance out spicy dishes or serve as a base in stuffed chili recipes.

How do I reduce the heat of a substitute chili?

• Remove the seeds and inner white ribs.
• Soak dried chilies in warm water before use.
• Add dairy products like yogurt or coconut milk to offset the burn.

Is Thai red chili paste the same as other chili pastes?

Thai red chili paste (nam prik pao) contains fish sauce, garlic, shrimp paste, and palm sugar, giving it a complex flavor. Other chili pastes may lack these elements, so adjust seasonings accordingly.

Can I freeze fresh chilies for later use?

Absolutely! Simply wash, dry, and store them in a freezer bag. No need to thaw — just chop frozen chilies directly into your dish.

Which substitute is best for curries?

Cayenne or dried arbol chilies are ideal for dry spice rubs in curries. If using fresh, serranos or jalapeños are solid choices depending on desired heat.
