Ingredients

For the Chili Garlic Sauce

• 6 large garlic cloves, finely chopped
• ¼ cup crushed red pepper flakes
• 2 tablespoons sesame seeds
• 1 cup (240 ml) neutral vegetable, canola, or sunflower oil
• 1 teaspoon salt, or to taste
• 1 teaspoon granulated sugar, optional
• 1 teaspoon toasted sesame oil, optional
• 1 tablespoon rice vinegar, optional

Note: The garlic, red pepper flakes, and sesame seeds are your supplied ingredients. The oil, salt, sugar, and optional flavor additions are suggested to complete the sauce.

Instructions

1. Prepare the Ingredients

Peel and finely chop the garlic cloves.

Avoid crushing the garlic into a paste. Finely chopped pieces give the sauce a wonderful texture and distribute the garlic flavor throughout the oil.

Measure the crushed red pepper flakes and sesame seeds into a heatproof bowl.

Add the salt and sugar, if using, and stir to combine.

Make sure the bowl is large enough to safely hold the hot oil.

2. Heat the Oil

Pour the vegetable oil into a small saucepan.

Heat over medium-low heat until the oil becomes hot, approximately 300–325°F (150–165°C).

You can test the temperature with a kitchen thermometer.

Avoid allowing the oil to smoke, as overheated oil can develop a bitter flavor and may scorch the garlic and chili flakes.

3. Cook the Garlic

Carefully add the finely chopped garlic to the warm oil.

Cook over low to medium-low heat for approximately 2–4 minutes, stirring frequently.

The garlic should become fragrant and lightly golden.

Watch it closely because chopped garlic can burn very quickly. Dark brown or burnt garlic will make the sauce bitter.

Continue cooking gently until the garlic is lightly golden and its moisture has cooked away.

4. Pour the Hot Oil Over the Chili Mixture

Remove the saucepan from the heat.

Carefully pour the hot garlic-infused oil over the bowl containing the crushed red pepper flakes and sesame seeds.

Pour slowly and in stages, stirring gently between additions.

The mixture will bubble and sizzle as the hot oil releases the flavor and aroma of the garlic, sesame, and chili.

Be careful during this step because the hot oil can splatter.

5. Add the Finishing Flavors

Allow the mixture to cool slightly.

Stir in the toasted sesame oil, if using, for an extra nutty aroma.

For a brighter, slightly tangy flavor, add the rice vinegar once the mixture has cooled sufficiently.

Taste carefully and adjust the salt or sugar according to your preference.

Mix thoroughly so the ingredients are evenly distributed.

6. Let the Flavors Develop

Allow the chili garlic sauce to cool completely.

As it rests, the crushed red pepper flakes, garlic, and sesame seeds release more of their flavor into the oil.

The color will deepen into a beautiful reddish-orange, and the aroma will become wonderfully rich and fragrant.

7. Transfer to a Jar

Transfer the completely cooled sauce into a clean, dry, food-safe airtight jar.

Use a clean spoon to make sure all the garlic, chili flakes, and sesame seeds are transferred.

Seal the jar and refrigerate immediately.

Expert Tips for the Best Chili Garlic Sauce

• Choose fresh garlic: Freshly chopped garlic delivers the strongest and most delicious flavor.
• Use good-quality chili flakes: Different brands vary in heat, so start with the recommended amount and adjust next time.
• Control the oil temperature: Oil that’s too hot can burn the garlic and chili flakes, creating an unpleasant bitter taste.
• Don’t overcook the garlic: Aim for lightly golden pieces rather than dark brown garlic.
• Pour the oil slowly: Adding it in stages helps distribute the heat and flavor evenly.
• Use a heatproof bowl: The oil will be extremely hot when poured over the chili mixture.
• Toast the sesame seeds lightly: This enhances their nutty flavor. Toast them in a dry pan before adding them to the bowl if desired.
• Adjust the spice level: Add more or fewer crushed pepper flakes depending on your preferred heat.
• Allow time for the flavors to develop: The sauce becomes more flavorful after resting in the refrigerator overnight.
• Use a clean, dry spoon: This helps prevent contamination and keeps the sauce fresher.

Delicious Variations

Extra-Spicy Chili Garlic Sauce: Add 1–2 teaspoons cayenne pepper or finely chopped dried hot chilies for an extra fiery kick.

Sweet Chili Garlic Oil: Increase the sugar to 1 tablespoon for a slightly sweeter balance against the heat.

Sichuan-Style Chili Oil: Add ½ teaspoon ground Sichuan peppercorns for a distinctive citrusy, tingling flavor.

Ginger Chili Garlic Sauce: Add 1 tablespoon finely minced fresh ginger alongside the garlic for a fragrant, spicy variation.

Smoky Chili Garlic Oil: Replace some of the regular pepper flakes with smoked chili flakes for a deeper, smoky flavor.

Extra Sesame Chili Sauce: Increase the sesame seeds to 3 tablespoons and add a little more toasted sesame oil for a stronger nutty taste.

Tangy Chili Garlic Sauce: Add an additional tablespoon of rice vinegar for a brighter, slightly acidic finish.

Soy Garlic Chili Oil: Stir in 1–2 teaspoons soy sauce when the mixture has cooled. This adds an extra savory, umami flavor, but the added moisture makes careful refrigeration especially important.

Crispy Shallot Chili Oil: Add 2 tablespoons finely sliced fried shallots for extra crunch and sweetness.

What to Serve with Chili Garlic Sauce

This flavorful sauce is incredibly versatile. Try serving it with:

• Steamed or pan-fried dumplings

• Garlic noodles
• Ramen and noodle soups
• Steamed white rice
• Scrambled or fried eggs
• Grilled chicken
• Roasted vegetables

Make-Ahead and Storage Instructions

Make Ahead: You can prepare the sauce ahead of time and refrigerate it so the garlic, sesame, and chili flavors have time to develop.

Refrigerator: Transfer the completely cooled sauce into a clean, airtight container and refrigerate at 40°F (4°C) or below. Because this recipe contains fresh garlic in oil, use it within 4 days. Do not store homemade garlic-in-oil mixtures at room temperature.

Freezing: For longer storage, freeze the sauce in small freezer-safe portions or ice cube trays. Transfer the frozen portions to a sealed freezer-safe container. Use within 2–3 months for best quality.

Thawing: Thaw portions in the refrigerator and use promptly. Do not refreeze previously thawed sauce.

Serving: Use a clean, dry spoon every time you take sauce from the jar. Discard the sauce if it has been left at room temperature for more than 2 hours.

Important Food Safety Note: Fresh garlic stored in oil can support the growth of Clostridium botulinum under certain conditions. Refrigeration does not make homemade garlic oil safe indefinitely. Never store this sauce in the pantry or leave it at room temperature for extended periods.

Frequently Asked Questions

How spicy is homemade Chili Garlic Sauce?

This recipe has a noticeable spicy kick from the ¼ cup of crushed red pepper flakes. The actual heat depends on the type and brand of chili flakes. Reduce the quantity for a milder sauce or increase it for extra heat.

Can I use fresh red chilies instead of crushed red pepper flakes?

Yes, but fresh chilies contain more moisture and will change the texture and storage characteristics. For this particular oil-based recipe, dried crushed red pepper flakes are the better choice.

Can I use olive oil instead of vegetable oil?

Yes, but a neutral oil such as sunflower, canola, or vegetable oil is recommended because it allows the garlic, chili, and sesame flavors to stand out.

Why did my chili garlic sauce taste bitter?

The garlic or chili flakes may have been overheated. Garlic burns quickly, so keep the heat low and remove the saucepan from the heat before pouring the oil over the chili mixture.

Can I make the sauce less spicy?

Absolutely! Reduce the crushed red pepper flakes to 2–3 tablespoons. You can also add a little more neutral oil to soften the heat, although this will change the yield and flavor intensity.

Can I make this sauce without sesame seeds?

Yes! Simply leave them out. The sauce will still have plenty of delicious garlic and chili flavor.

Do I need to refrigerate homemade Chili Garlic Sauce?

Yes. This recipe contains fresh garlic submerged in oil. Refrigerate immediately after cooling and use within 4 days.

Can I use this sauce for cooking?

Definitely! Add it to stir-fries, fried rice, noodle dishes, marinades, and soups. You can also use a small spoonful to season roasted vegetables or grilled proteins.

Does the sauce become more flavorful overnight?

Yes! The flavors can develop as the ingredients rest together in the refrigerator. Just remember that it must remain refrigerated and be used within 4 days.

Can I make a larger batch?

Yes, but it’s best to prepare smaller batches that you can safely use within the recommended refrigerated storage period. Avoid keeping large quantities of homemade garlic oil for extended periods.
