This black bean chilli oil recipe transforms simple pantry staples into a smoky, umami-packed condiment that elevates everything from noodles to rice bowls.

I developed this after craving a condiment with depth—something that adds heat, richness, and a touch of earthiness without overpowering dishes.
The process is straightforward: simmer black beans, chilli, and aromatics until fragrant, then blend with soy sauce and sesame oil for a silky-smooth (or chunky, if you prefer) finish. Adjust the heat by adding more chilli flakes or a dash of miso for extra umami.
What makes this recipe stand out is its adaptability—use it as a dipping sauce, stir it into soups, or drizzle it over grilled meats for instant flavor.

This isn’t just another chilli oil—it’s a game-changer for home cooks who love bold, complex flavors without the fuss.

Ingredients for black bean chilli oil
Pantry staples meet bold flavors in this smoky, umami-packed vegan chilli oil.
| Ingredient | Amount | Notes |
|---|---|---|
| Black Beans 🫘 | 1 cup | Drained and rinsed, canned or cooked |
| Chilli Flakes 🌶️ | 2 tbsp | Adjust for heat preference |
| Garlic Cloves 🧄 | 6 cloves | Peeled and roughly chopped |
| Sesame Oil 🫒 | ½ cup | Toasted for nutty aroma |
| Light Soy Sauce 🍶 | ¼ cup | For umami depth |
| White Vinegar 🍶 | 1 tbsp | Balances richness |
| Ginger Root 🌿 | 1 tbsp | Freshly grated, optional |
| Sesame Seeds 🌰 | 1 tbsp | Toasted for garnish |
| Water 💧 | ¼ cup | For blending consistency |
| Salt 🧂 | ½ tsp | Kosher or sea salt |
Black beans are the star here—they give that creamy texture while soaking up all the smoky flavors. Canned beans work perfectly (no need to cook them first), but if you're using dried, soak overnight. For chilli flakes, Penzeys or local spice shops have the best quality—look for vibrant red color, not dull brown. Garlic? Fresh is non-negotiable—the frozen stuff just doesn't cut it here. Sesame oil can be tricky: toasted sesame oil gives that nutty aroma, while regular is more neutral. I always grab mine from Asian markets where they keep it fresh.
No sesame oil? Avocado oil or peanut oil will work in a pinch, though the flavor won't be identical. Short on ginger? Skip it—this sauce is still delicious. Want more depth? Add a dash of miso paste (white or red) when blending. For extra umami without soy sauce, try vegan Worcestershire sauce. The vinegar balances everything—apple cider vinegar adds a fruity note if you prefer. And if you're making this for a crowd, double the batch—it disappears fast!
This sauce keeps beautifully. Store it in a clean glass jar with a tight seal—fridge life is 2-3 weeks, freezer life 6 months. I like to portion it into small jars so I can grab just what I need. The flavors actually improve over time as everything melds together. Pro tip: Toast your sesame seeds right before using—just 30 seconds in a dry pan makes all the difference. And if you make extra, gift it. Everyone loves a good chilli oil!

Step-by-step instructions for black bean chilli oil
Transform simple pantry staples into a bold, aromatic chilli oil that elevates every dish.
Toast the Sesame Seeds and Dry Ingredients
Heat a dry skillet over medium heat. Add the 1 tablespoon sesame seeds and toast for 1-2 minutes until they release their nutty aroma and turn a rich golden brown. Watch closely—they burn quickly once they start to darken. Immediately transfer to a small bowl and set aside.
In the same skillet, add the 2 tablespoons chilli flakes and toast for 30 seconds until fragrant. Remove from heat and let cool for 1 minute—this prevents steam when we combine everything later. The toasted seeds and chilli will form the aromatic base of your oil, so don't skip this step. If you prefer milder heat, reduce the chilli flakes to 1 tablespoon now.
Blend the Black Bean Base
In a blender, combine the 1 cup drained black beans, 6 cloves peeled garlic, 1 tablespoon freshly grated ginger root, 0.25 cup light soy sauce, 1 tablespoon white vinegar, 0.25 cup water, and 0.5 teaspoon salt. Blend until completely smooth, about 30-45 seconds. You want a thick, paste-like consistency that will emulsify with the oil later.
Taste the mixture—it should be tangy from the vinegar, umami-rich from the soy sauce, and have a subtle garlic-ginger kick. If it needs more brightness, add ½ teaspoon additional vinegar. This blend forms the flavor foundation that will infuse the oil, so take your time getting it balanced. Keep the blender ready as we'll use it again shortly.
Infuse the Oil with Flavor
Pour the 0.5 cup sesame oil into a heavy saucepan and place over medium-low heat. Add the blended black bean mixture and stir constantly with a wooden spoon for 5 minutes. The oil should gradually darken and develop a rich, aromatic steam. You're looking for the oil to reach about 160°F—it should be warm enough to infuse but not smoking.
Here's where the magic happens: the oil will begin to emulsify with the bean mixture, creating a thick, paste-like consistency. If it starts to separate or get too thick, add 1 tablespoon water at a time until it reaches a smooth, pourable texture. Remove from heat before it reaches 180°F—any hotter and the oil will lose its delicate flavor balance.
Finish and Rest for Maximum Flavor
Return the pan to low heat and stir in the toasted sesame seeds and chilli flakes. Cook for an additional 2 minutes, allowing the seeds to release their final nutty notes into the oil. The mixture should now be thick, glossy, and deeply aromatic with visible flecks of chilli and seeds suspended throughout.
Transfer the chilli oil to a heatproof jar and let it cool to room temperature. This resting period allows all the flavors to meld completely—at least 30 minutes, but overnight in the refrigerator is even better. The oil will thicken as it cools, which is normal. When ready to use, simply stir vigorously to re-emulsify before drizzling over noodles, dumplings, or grilled meats.
Pro Tips For Making Black Bean Chilli Oil
- CRUSH THE BEANS: Drain and rinse your black beans, then mash them roughly with a fork—no food processor. You want texture, not paste. I learned this the hard way after turning my first batch into a gloopy mess that refused to emulsify with the oil.
- TOAST THE CHILLI: Dry-toast your chilli flakes in a small pan for 30 seconds before adding oil. This deepens their flavor and prevents them from turning bitter when they hit the sesame oil. (Yes, even if you’re impatient like me—wait for the aroma to hit.)
- LOW AND SLOW WITH GARLIC: Cook the minced garlic on the lowest heat setting possible—just above a simmer. Garlic burns faster than you think, and once it’s bitter, there’s no fixing it. If your pan’s too hot, pull it back and let it sweat out its moisture first.
- EMULSIFY WITH SOY: Add the light soy sauce last, when the oil is hot but not smoking. Stir like you’re trying to win a race—this helps the oil and beans bind properly. Skip this, and you’ll end up with a sad, separated oil. (Your future self will notice.)
Creative variations of this recipe
Spicy & Smoky
For extra heat, add 1 teaspoon cayenne pepper or ½ teaspoon smoked paprika to the toasted chilli flakes. I like to toast these together for 30 seconds—the smoke deepens the flavor profile beautifully.
If you love fire, blend in 1-2 dried Thai bird's eye chilies—they add a fruity, intense heat that pairs perfectly with the black beans. 🌶️
Creamy & Tangy
Want a richer texture? Stir in 2 tablespoons tahini—its nutty, creamy quality balances the oil's boldness. For tang, add 1 tablespoon lime juice—it brightens the sauce and cuts through the richness.
I often make a double batch with these tweaks for tacos or grain bowls. The contrast is amazing!
Umami Boost
For deeper savory notes, blend in 1 tablespoon miso paste—white for mildness or red for intensity. Or try 1 teaspoon vegan Worcestershire sauce—it adds complexity without overpowering.
I once added ¼ cup finely chopped shiitake mushrooms—they soaked up the flavors like a sponge while adding earthiness. 💫
Herb-Infused Twist
Fresh herbs elevate this sauce instantly. Fold in 1 tablespoon chopped cilantro or Thai basil—they add brightness and freshness. For a Mediterranean touch, use 1 teaspoon dried oregano—it pairs surprisingly well with the smoky chilli.
I like to garnish with extra herbs right before serving for a pop of color and flavor.
Sweet & Spicy
Balance the heat with a touch of sweetness. Stir in 1 teaspoon maple syrup or agave—it smooths out the chilli while adding depth. For a tropical twist, add ½ teaspoon grated lime zest—it’s a game-changer for seafood dishes.
I once drizzled this version over grilled pineapple and shrimp—divine!
Nutty Crunch
Add texture with toasted nuts. Sprinkle in 1 tablespoon chopped peanuts or cashews—they provide a satisfying crunch. For extra richness, blend in 1 tablespoon peanut butter—it’s a secret weapon for stir-fries. I love this version with noodles—every bite is a flavor explosion. 🥜

Frequently asked questions
Can I use this chilli oil on non-vegan dishes?
This black bean chilli oil works beautifully as a finishing sauce for grilled meats, roasted vegetables, or even pizza. The smoky umami flavors complement proteins perfectly. Just drizzle it over your dish at the end to avoid overpowering the main ingredient.
How do I adjust the heat level?
For milder heat, reduce the chilli flakes to 1 tablespoon and omit the cayenne or Thai chilies. For extra spice, add ½ teaspoon cayenne pepper or blend in 1-2 dried Thai chilies. Always taste as you go—you can't take heat out, but you can build it up!
What if my chilli oil separates after storing?
This is normal! Simply stir vigorously before using. For a smoother texture, blend briefly with 1 tablespoon water until emulsified. The oil will naturally separate as it cools, but it always comes back together when stirred. Store in a sealed jar to maintain freshness.
Can I make this without sesame oil?
Yes, but the flavor will differ. Use avocado oil or peanut oil for a neutral base, though sesame oil's nutty aroma is key. For a vegan-friendly alternative, try toasted coconut oil—it adds a subtle sweetness that works surprisingly well. Just adjust the amount to maintain the same ratio.
What are the best dishes to use this chilli oil with?
This versatile sauce shines on noodles, dumplings, rice bowls, and grilled proteins. Try it as a dipping sauce for veggie spring rolls or a marinade for tofu. For extra drama, drizzle it over avocado toast or mix it into mayo for a spicy sandwich spread. The possibilities are endless!
