You're tossing a green papaya salad together when you realize the fresh Thai chilis are nowhere in the fridge. The recipe counts on their sharp, immediate heat and bright citrusy bite to balance the sweet and sour dressing.
Thai chili peppers bring high heat (50,000-100,000 Scoville units) and a crisp texture that holds up in raw and cooked dishes. Standard jalapeños won't match that intensity or crunch.
Most produce sections carry milder peppers year-round. A few fresh and dried options can fill that heat gap with small adjustments.
Bird's eye chilis and serrano peppers match Thai chilis' sharp heat and crisp bite in fresh salads and stir-fries-use 1:1 for bird's eye or 1 serrano per 2 Thai chilis. Jalapeños work in cooked sauces but need 1 jalapeño per 3 Thai chilis due to milder heat. Dried cayenne powder (¼ teaspoon per fresh chili) adds heat but loses texture and fresh aroma.

1. Bird's Eye Chili Pepper 🔥
Bird's eye chilis step in when you need high heat and crisp texture almost identical to Thai chilis. The flavor runs bright and sharp with mild fruitiness.
Use 1 bird's eye chili per 1 Thai chili pepper in any recipe. They work everywhere Thai chilis do-fresh salads, dipping sauces, stir-fries, and curries.
- ✅ Matches Thai chili heat intensity (50,000-100,000 Scoville)
- ✅ Same crisp bite and fresh aroma
- ✅ Holds shape in raw and cooked applications
- ⚠️ Slightly different fruity undertones than Thai varieties
The size and structure mimic Thai chilis so closely that most recipes won't need adjustment. If you're making som tam or larb and need that sharp heat to cut through lime and fish sauce, this is it.
2. Serrano Pepper 🌶️
Serrano peppers bring moderate heat (10,000-25,000 Scoville) and a crisp, bright flavor that works in both fresh and cooked dishes. The texture stays firm when sliced thin or diced.
Use 1 serrano per 2 Thai chilis. The heat runs lower but the crunch and brightness stay close.
- 🍳 In cooking: Works in stir-fries and curries with longer cook times
- 🥗 Raw/fresh: Holds up in salsas and fresh salads
Serranos are easier to find year-round than Thai chilis in most grocery stores. If you need more on Serrano Pepper swaps by recipe type, we've tested those too.
3. Jalapeño Pepper 🫑
Jalapeños add mild heat and fresh green notes but run much softer than Thai chilis. The heat level sits around 2,500-8,000 Scoville-you'll need more to match intensity.
Use 1 jalapeño per 3 Thai chilis in cooked sauces and mild curries. The vegetal flavor works better when simmered than sliced raw.
- ✅ Widely available in most stores
- ✅ Fresh green brightness in cooked dishes
- ⚠️ Much lower heat requires tripling the amount
- ⚠️ Softer texture breaks down faster in raw applications
Jalapeños shine in cooked applications where the heat mellows and blends into the dish. Skip them in raw papaya salad or fresh Vietnamese spring rolls-they won't bring the sharp bite you need.

4. Dried Cayenne Pepper Powder 🔴
Cayenne powder delivers fiery heat (30,000-50,000 Scoville) and sharp spice without any fresh texture or aroma. It works only in cooked dishes where you need heat but can skip the crisp bite.
Use ¼ teaspoon cayenne powder per 1 fresh Thai chili. Add it early in cooking so the heat distributes evenly through sauces and marinades.
- 🍳 In cooking: Blends into curries, stir-fry sauces, and soups
- ⚠️ Skip for fresh dishes: No texture or fresh aroma
Cayenne brings heat but loses everything else-no crunch, no bright flavor, no visual pop. It's a backup for cooked dishes only.
If you need more heat options, Cayenne Pepper substitutes for cooking covers other dried spices.
5. Red Pepper Flakes 🌶️
Red pepper flakes add fiery heat and a slight smokiness but no fresh qualities. The flakes rehydrate slightly in liquids but stay coarse.
Use ½ teaspoon red pepper flakes per 1 fresh Thai chili in spicy sauces, marinades, and stir-fries. Add them early so they bloom in oil or liquid.
- 🍳 In cooking: Works in pasta sauces, pizza, and chili oil
- ⚠️ Skip for raw dishes: Coarse texture and no fresh crunch
Red pepper flakes work when you're building a cooked sauce or marinade and need heat without worrying about texture. They won't substitute in fresh applications like salads or garnishes.

6. Fresh Fresno Chili 🌶️
Fresno chilis bring mild heat (2,500-10,000 Scoville) and fruity undertones with a crisp texture that holds up in raw dishes. The flavor runs sweeter and less sharp than Thai chilis.
Use 1 Fresno chili per 2 Thai chilis in fresh salads, salsas, and garnishes. The heat stays lower, so expect a milder kick.
- 🥗 Raw/fresh: Works in fresh salads and salsas
- ✅ Similar crisp texture and bright color
- ⚠️ Fruitier and sweeter than Thai chilis
Fresnos work when you want fresh crunch and color but can accept lower heat and a sweeter profile. They won't cut through rich flavors the way Thai chilis do.

7. DIY Chili Paste Blend (Crushed Red Pepper + Fresh Garlic + Lime Juice) 🍋
DIY chili paste combines heat, sharpness, and brightness in a blended form that mimics the flavor of fresh Thai chilis without the crisp texture. The garlic and lime juice rebuild the aromatic punch.
Mix 1 teaspoon crushed red pepper + ½ teaspoon minced garlic + 1 teaspoon lime juice per 1 fresh chili. Use it in cooked sauces, marinades, and dressings where texture matters less.
- 🍳 In cooking: Works in stir-fry sauces and marinades
- ✅ Rebuilds heat and brightness without fresh chili
- ⚠️ No crisp texture for raw applications
This blend works when you're making a cooked sauce or marinade and need the flavor more than the texture. It won't substitute in fresh salads or garnishes where the crisp bite matters.

Frequently Asked Questions
You can, but use 1 jalapeño per 3 Thai chilis to match the heat. Jalapeños bring milder heat and a more vegetal flavor that won't cut through the sweet tamarind sauce as sharply. They work better in cooked dishes than as a fresh garnish.
Bird's eye chilis are the closest match-use them 1:1. They bring the same sharp heat (50,000-100,000 Scoville) and crisp texture that holds up when pounded in a mortar. Serrano peppers work as a backup but need 1 serrano per 2 Thai chilis due to lower heat.
Dried chilis won't match the fresh crunch or bright aroma of Thai chilis. Use cayenne powder (¼ teaspoon per fresh chili) or red pepper flakes (½ teaspoon per chili) in cooked dishes only. Skip dried substitutes in fresh salads or raw applications.
Bird's eye chilis match Thai chili heat almost exactly, so use the same amount your recipe calls for. If you want less heat, remove the seeds and membranes before slicing-that's where most of the capsaicin concentrates. You can also use fewer whole chilis and taste as you go.
No, Fresno chilis are much milder-2,500-10,000 Scoville compared to Thai chilis' 50,000-100,000. Use 1 Fresno per 2 Thai chilis if you want lower heat. Fresnos bring a sweeter, fruitier flavor that works better in mild dishes than spicy curries or salads.
