Gochugaru flakes are the backbone of kimchi, tteokbokki, and Korean BBQ marinades — their smoky-sweet character and brick-red color are genuinely hard to replicate. When you're mid-recipe and the bag is empty, you need a substitute that matches both the heat and the flavor profile, not just one or the other. The options below are ranked by how closely they mirror what gochugaru actually does in a dish.
These alternatives are ranked by how closely they match Gochugaru Flakes’s heat level and flavor profile. Use the conversion ratios to adjust quantities in your recipe.
#1
Gochugaru (Whole Flakes vs. Powder Form) Closest Match
If your recipe calls for gochugaru flakes specifically, the same chile in powder form is your closest swap. Both land in the 1,500-10,000 SHU range and share identical flavor DNA — that signature smoky sweetness that makes Korean cooking so distinctive. The smoky-sweet Korean chile profile stays intact; you just lose some texture. Use ¾ teaspoon powder for every 1 teaspoon flakes since ground spice packs more surface area per volume. Color contribution remains the same vivid red.
#2
Chipotle Runner-Up
Chipotle is the dark horse here. Before thinking about numbers, consider the flavor: smoke-forward with a dried fruit sweetness that echoes gochugaru more closely than most Western chiles. At 2,500-8,000 SHU, the chipotle's smoky dried-chile depth sits comfortably within gochugaru's heat window. Use a 1:1 ratio for flakes, but taste first — chipotle carries more earthiness and less of that clean sweetness. Works best in braises, stews, and marinades where the smoke can bloom.
#3
Fresno Pepper (Dried and Crushed) Also Great
Fresh Fresnos won't do the job, but dried and crushed Fresnos get surprisingly close. Their 2,500-10,000 SHU range overlaps almost perfectly, and the Fresno's fruity-smoky dried character mimics gochugaru's brightness better than most Latin American chiles. Start with a 1:1 substitution and adjust up slightly if your Fresnos are on the milder end. The red color contribution is solid. Best for kimchi-style applications where the fruity note matters.
#4
Puya Pepper
Puya is underrated in this context. Sitting at 5,000-8,000 SHU, it's a touch hotter than mid-range gochugaru, but the Puya's fruity heat with smoky undertones makes it a natural fit for Korean-adjacent dishes. Use ¾ teaspoon crushed Puya for every 1 teaspoon gochugaru flakes to keep heat in check. The color is slightly darker and the flavor leans more toward dried cherry than the clean sweetness of Korean chile — works well in soups and stews, less ideal for fresh kimchi.
#5
Morita Pepper
Morita is essentially a smoke-dried jalapeño, which puts its deep smoky-fruity heat profile in interesting territory as a gochugaru stand-in. At 5,000-10,000 SHU, it runs hotter than mild gochugaru batches, so dial back to ½ teaspoon crushed Morita per teaspoon of flakes. The smoke is more aggressive than gochugaru's subtle dried-fruit smokiness, so this substitute works better in bold dishes — think braised meats, spicy tofu stews — rather than anything where gochugaru's delicacy is the point.
#6
Pasilla de Oaxaca
This one requires some hunting, but the payoff is real. The Pasilla de Oaxaca's rich, smoky depth at 4,000-10,000 SHU makes it one of the more complex substitutes on this list. It's a smoked chile (like chipotle) but with a richer, almost chocolatey undertone that pairs well with fermented flavors in kimchi or doenjang-based dishes. Use a 1:1 ratio for crushed flakes. Color will be darker — more brown-red than the vivid brick of gochugaru — which matters if presentation is a priority.
#7
Korean Green Pepper (Dried)
This is the lowest-heat option at 1,500-10,000 SHU, and in dried, crushed form the Korean green pepper's mild grassy flavor shares the same C. annuum genetics as gochugaru. The flavor profile skews grassy and mild rather than smoky-sweet, so it's best used when heat level match matters more than flavor match. Swap 1:1 and add a small pinch of smoked paprika to approximate the smokiness gochugaru brings. Useful for dishes where you want Korean chile character without adding heat.
For a broader look at where these peppers fall on the medium SHU bracket, that hub covers the full range of chiles operating in this zone. If you're comparing gochugaru flakes directly against chipotle for a specific recipe, the gochugaru vs. chipotle heat gap and flavor differences break it down side by side.
Cayenne seems like an obvious swap given its red color and powdered form, but it runs 30,000-50,000 SHU — three to five times hotter than most gochugaru — and completely lacks the smoky-sweet character that defines the Korean chile. Drop it into kimchi at a 1:1 ratio and you'll blow out the dish.
Ancho chile is mild enough at 1,000-2,000 SHU and has some dried-fruit sweetness, but the flavor skews toward raisin and chocolate rather than the clean, bright smokiness of gochugaru. It also contributes a muddy brown color instead of the vivid red that matters for dishes like kimchi or tteokbokki.
Paprika (standard sweet) gets recommended often as a gochugaru substitute, but regular paprika has almost no heat and a flat, one-dimensional flavor. Even smoked paprika lacks the chile's natural sweetness and brightness. It can work as a color fix in a pinch, but as a flavor substitute it falls short of what any of the seven ranked options above can deliver.
Substitution Tip
When substituting Gochugaru Flakes (2K–10K SHU), always start with less of a hotter substitute and add more to taste. For milder substitutes, you can increase the quantity.

Standard crushed red pepper flakes (typically made from cayenne or generic hot chiles) run 30,000-50,000 SHU — far hotter than gochugaru's 1,500-10,000 SHU range and without the smoky-sweet flavor. If that's all you have, use about ¼ teaspoon per teaspoon of gochugaru and expect a sharper, less nuanced result.
Dried and crushed Fresno peppers come closest for kimchi because their fruity brightness and red color approximate what gochugaru contributes to fermentation. Chipotle works in a pinch but adds more smoke than a traditional kimchi flavor profile calls for.
Gochugaru is dried chile flakes; gochujang is a fermented paste made from gochugaru, glutinous rice, and salt — they're not interchangeable at a 1:1 ratio. If a recipe calls for gochugaru flakes and you only have gochujang, use about 1 teaspoon paste per tablespoon of flakes and reduce any salt or liquid in the recipe.
Start with 1 tablespoon of crushed chipotle for every tablespoon of gochugaru flakes — the heat ranges overlap well enough for a direct swap. Chipotle's smoke is more aggressive, so taste as you go and back off slightly in dishes where gochugaru's sweetness is the dominant note.
Yes — gochugaru's vivid brick-red color is part of what makes kimchi and tteokbokki visually distinctive. Fresno and Puya substitutes maintain decent red color, while Morita and Pasilla de Oaxaca will push dishes toward a darker, browner hue. Adding a small amount of sweet paprika alongside any substitute can help restore the expected color.
