Gochujang vs Gochugaru: 7 Differences & When to Use Each

Two famous Korean chili ingredients. One is a fermented paste; the other is dried pepper flakes.

You're making Korean spicy chicken for dinner.

The recipe says, "Add one tablespoon of gochujang."

You open your pantry and find a bag labeled "gochugaru."

"Close enough, right? They're both red and spicy."

Not so fast!

One is a thick, fermented chili paste. The other is dried Korean red pepper flakes.

Swap them without adjusting your recipe, and dinner might turn out very differently than you expected.

So which one should you use? Let's make it simple.

Quick Answer: Gochujang vs Gochugaru

Gochujang (고추장) is a thick, fermented Korean chili paste. It adds sweetness, saltiness, savory depth, and heat.

Gochugaru (고춧가루) is Korean red pepper powder or flakes. It adds chili flavor, red color, and heat without the fermented sweetness of gochujang.

Easy way to remember: Gochujang builds the sauce. Gochugaru brings the pepper.

1. Meet the Two Ingredients

GOCHUJANG

The Flavor Builder

• Texture: Thick and sticky
• Flavor: Sweet, spicy, salty, savory
• Fermented: Yes
• Common uses: Marinades, sauces, stews
• Best at: Creating rich, flavorful coatings

GOCHUGARU

The Chili Specialist

• Texture: Dry flakes or powder
• Flavor: Chili-forward, sometimes fruity
• Fermented: No
• Common uses: Kimchi, soups, seasoning
• Best at: Adding pepper flavor and red color

If These Two Ingredients Could Talk...

Gochujang: "I bring sweetness, savory depth, and a thick, rich texture to your sauce."

Gochugaru: "And I bring bold chili flavor, vibrant red color, and extra heat without making everything sweeter!"

Home Cook: "So you're not competitors?"

Gochujang: "Not at all. Some Korean recipes need both of us!"

And that's the secret: They have different jobs, even when they're used in the same dish.

2. Seven Key Differences You Should Know

Difference 1: Paste vs Flakes

Gochujang is a thick, sticky paste. It can coat meat, vegetables, and rice cakes.

Gochugaru is dry chili powder or flakes. It adds pepper flavor but doesn't thicken a sauce the same way.

Imagine trying to make a sticky chicken glaze using only dry chili flakes. You'd still need other ingredients to build the sauce.

Difference 2: Fermented vs Unfermented

Gochujang gets part of its complex flavor from fermentation.

Traditional gochujang combines Korean chili powder, grains, fermented soybean ingredients, and salt.

Gochugaru is made from dried Korean red peppers that are ground into flakes or powder.

The flakes themselves aren't fermented, although they're commonly used in fermented foods like kimchi.

Difference 3: Sweet-Savory vs Pepper-Forward

Gochujang delivers several flavors at once: sweetness, saltiness, chili heat, and fermented savory depth.

Gochugaru focuses on the pepper. Depending on the variety, it may taste mildly sweet, fruity, or slightly smoky.

A Quick Taste Test

You: "Why does my sauce taste sweeter after I add more gochujang?"

Gochujang: "Because I'm not just chili. I bring sweetness and seasoning, too."

Gochugaru: "Need more chili flavor without all that extra sweetness? That's where I come in."

Difference 4: Neither Is Always Hotter

There's no universal winner in a heat contest.

Gochujang varies by brand and recipe. Some versions are mild, while others are very hot.

Gochugaru also comes in different heat levels.

Gochujang's sweetness may make the heat feel more rounded, while gochugaru provides a more direct pepper flavor.

Beginner tip: Start with a small amount. Don't assume that all Korean red chili products have the same heat level.

Difference 5: Different Ingredient Lists

Gochujang commonly contains Korean chili powder, grains, fermented soybean ingredients, and salt.

Plain gochugaru is generally made from dried chili peppers.

Some gochujang products contain wheat, barley, or soy. Check the package if you have food allergies or dietary restrictions.

Difference 6: Different Jobs in the Kitchen

Gochujang works well when a recipe needs a thick sauce or marinade.

Gochugaru works well when you want to season a dish with chili flavor, deepen the red color, or adjust heat.

That's why the two can work together rather than replace each other.

Difference 7: Different Storage Needs

Many commercial gochujang products recommend refrigeration after opening.

Gochugaru should be protected from heat, light, and moisture. Refrigeration or freezing can help preserve quality during longer storage.

Always follow the instructions on the actual product package.

3. Which One Should You Use for Korean Food?

Now for the question that actually matters when you're cooking dinner.

Dish	Common Choice	Reason
Kimchi	Gochugaru	Chili flavor and red color
Bibimbap sauce	Gochujang	Rich, sweet-savory sauce
Tteokbokki	Gochujang; sometimes both	Thick, spicy-sweet sauce
Spicy chicken	Gochujang; sometimes both	Glaze and extra chili flavor
Kimchi stew	Often gochugaru	Additional chili heat
Spicy pork	Often both	Balanced marinade
Vegetable side dishes	Often gochugaru	Chili seasoning

Korean recipes vary by household and region. These are common choices rather than universal rules.

Let's Settle This at the Dinner Table

You: "I'm making kimchi. Who's coming?"

Gochugaru: "That's my specialty!"

You: "What about a sticky Korean chicken glaze?"

Gochujang: "I've got the rich sauce covered."

You: "And spicy pork?"

Gochujang: "Let's work together."

Gochugaru: "Now you're cooking!"

4. Why Do Some Korean Recipes Use Both?

If gochujang already contains chili, why add gochugaru?

Because adding more gochujang doesn't just add heat. It can also increase sweetness, saltiness, and the amount of thick paste in the dish.

Gochugaru gives cooks another way to adjust pepper flavor and color.

Think of It Like a Team

Gochujang: Builds the sauce's body and sweet-savory flavor.

Gochugaru: Adds more chili character without adding the same fermented sweetness.

Together, they can create a more balanced sauce than simply using more of one ingredient.

Gochujang adds rich sauce flavor. Gochugaru adds chili character and red color. Some dishes use both.

5. Can You Substitute Gochugaru for Gochujang?

Not directly.

Gochugaru doesn't contain gochujang's sweetness, saltiness, fermented soybean flavor, or thick consistency.

But if you're missing gochujang, you can make a quick alternative for certain cooked sauces.

Quick Gochugaru-Based Substitute

Ingredients

• 1 teaspoon gochugaru
• 2 teaspoons white miso
• 1/2 teaspoon honey or brown sugar
• A few drops of water, as needed

Instructions

1. Mix gochugaru, miso, and sweetener.
2. Add water gradually until the mixture becomes a paste.
3. Let it rest briefly so the pepper softens.
4. Taste and adjust before adding it to your recipe.

Use this as an experimental starting alternative for approximately 1 tablespoon of gochujang in some marinades or cooked sauces.

The flavor won't be identical. Miso commonly contains soy and may contain wheat or barley.

6. Can You Use Gochujang Instead of Gochugaru?

Sometimes in cooked sauces and soups, but it's not a one-to-one swap.

Gochujang adds sweetness, saltiness, and moisture along with chili flavor.

If you're experimenting in a soup, start with a little gochujang and reduce other salty or sweet ingredients if needed.

But for traditional-style kimchi, gochujang generally isn't a good replacement for gochugaru.

Remember: There is no universal tablespoon-for-tablespoon conversion between gochujang and gochugaru.

7. Making Kimchi? Here's What to Buy

For traditional-style red kimchi, choose gochugaru.

It gives the seasoning its familiar pepper flavor and vibrant red color without turning it into a sweet, thick paste.

The Kimchi Question

You: "Can I just use gochujang in my kimchi?"

Gochugaru: "If you're following a traditional-style recipe, you'll usually want me instead."

Look for Korean red pepper flakes intended for kimchi and check whether the recipe calls for a coarse or fine grind.

8. How to Buy Both Ingredients in the U.S.

You can often find gochujang and gochugaru at Korean supermarkets, Asian grocery stores, online food retailers, and some larger U.S. supermarkets.

Buying Gochujang

• Look for "Korean Hot Pepper Paste."
• Choose a beginner-friendly heat level.
• Check whether it's paste or bottled sauce.
• Review allergen information.
• Start with a small tub.

Buying Gochugaru

• Look for "Korean Red Pepper Flakes."
• Choose the grind your recipe needs.
• Check heat level if available.
• Look for fresh, well-sealed packaging.
• Store carefully to preserve color.

One more thing: Generic crushed red pepper flakes from the pizza aisle aren't necessarily the same as Korean gochugaru.

They may differ in heat, texture, and flavor.

9. Which One Should Beginners Buy First?

Choose Gochujang If...

You want to make bibimbap sauces, spicy chicken glazes, or tteokbokki.

Choose Gochugaru If...

You want to make kimchi, season Korean soups, or add chili flavor without adding a thick paste.

Choose Both If...

You're planning to cook Korean food regularly and want more control over heat, sweetness, and texture.

For many first-time Korean home cooks, gochujang is an approachable first purchase because you can mix it into a quick sauce.

If homemade kimchi is your main goal, buy gochugaru first.

10. Three Easy Kitchen Experiments

Want to understand the difference instead of just reading about it?

Try these simple ideas.

Experiment 1: Gochujang Rice Bowl Sauce

• 1 tablespoon gochujang
• 1 teaspoon sesame oil
• 1 teaspoon rice vinegar
• 1–2 teaspoons water

Whisk until smooth and drizzle over cooked rice, vegetables, and your favorite protein.

Notice: The sweet-savory depth and thick sauce texture.

Experiment 2: Gochugaru Seasoning Oil

• 1 teaspoon gochugaru
• 1 tablespoon neutral oil
• A small pinch of salt

Warm the oil gently over low heat. Remove it from the heat, then carefully stir in the gochugaru.

Let it infuse briefly without burning the pepper. Use a small amount over cooked vegetables or noodles.

Notice: The pepper aroma, red color, and direct chili flavor.

Handle hot oil carefully. Never add water to hot oil.

Experiment 3: Use Both Together

• 1 teaspoon gochujang
• 1/2 teaspoon gochugaru
• 1 teaspoon honey
• 1 teaspoon soy sauce
• 1–2 teaspoons water

Whisk together and warm gently. Use as a small finishing glaze for fully cooked chicken or tofu.

Notice: The rich paste flavor plus the extra pepper character.

Soy sauce may contain soy and wheat. Adjust the seasoning to taste.

11. Five Mistakes That Can Change Your Dish

Mistake 1: Swapping Them Without Adjustments

Dry flakes and fermented paste behave differently. You'll usually need to change other ingredients, too.

Mistake 2: Using Generic Chili Flakes for Kimchi

The heat and flavor may differ from Korean gochugaru.

Mistake 3: Adding More Gochujang Just for Heat

You'll also add sweetness and saltiness.

Mistake 4: Ignoring the Grind

Fine gochugaru and coarse flakes behave differently in sauces and seasoning mixes.

Mistake 5: Burning the Pepper

Gochugaru can become bitter if scorched in very hot oil.
