Sauces & Condiments
This black bean chilli oil recipe transforms every dish with its bold, smoky umami punch that lingers long after the first bite.
The secret lies in frying black beans until crispy, then infusing them into hot oil with garlic, chilli flakes, and a touch of Sichuan peppercorn for that signature tingling heat. I developed this recipe after craving a condiment that could elevate everything from noodles to roasted vegetables—without overpowering them.
The process is straightforward but requires patience: toast the beans until golden and fragrant, then steep them in oil with aromatics until the flavors meld into a rich, aromatic infusion.
What you end up with is a deep red, velvety oil packed with layers of spice, nuttiness, and subtle sweetness from the black beans. It’s the kind of condiment that makes even simple meals feel like a restaurant experience.
Use it to drizzle over steaming bowls of ramen, toss with stir-fried greens, or serve as a dipping sauce for crispy fries. The oil keeps well in the refrigerator for up to a month, though I rarely have any left that long.
This isn’t just a condiment—it’s a flavor multiplier that turns ordinary dishes into something extraordinary.
For an extra kick, add a pinch of smoked paprika or a splash of soy sauce to the oil while infusing. The possibilities are endless, but the base recipe is foolproof. Let’s make this chilli oil today—your taste buds will thank you.
Ingredients for black bean chilli oil
Nine bold ingredients for a condiment that turns simple meals into restaurant-worthy dishes.
| Ingredient | Amount | Notes |
|---|---|---|
| Dried Black Beans 🌱 | ½ cup | Soaked overnight or quick-soaked |
| Neutral Oil (Avocado or Vegetable) 🫒 | 1 cup | High smoke point preferred |
| Garlic Cloves 🧄 | 4 cloves | Minced for infusion |
| Red Chili Flakes 🌶️ | 2 tbsp | Adjust for heat preference |
| Sichuan Peppercorns 🌶️ | 1 tsp | Lightly toasted first |
| Smoked Paprika 🌶️ | 1 tbsp | For extra smokiness |
| Fresh Ginger 🌿 | 1 tbsp | Finely grated or minced |
| Soy Sauce (or Tamari) 🥢 | 1 tbsp | For umami depth |
| Sesame Oil 🫒 | 1 tbsp | For aroma finish |
| Sea Salt 🧂 | ½ tsp | Kosher or fine grain |
Black beans are the star here—dried works best (canned lacks texture), so grab a bag from the bulk section at Whole Foods or your local Asian market. They need to be toasted until crispy, so don’t skip this step. For Sichuan peppercorns, Penzeys or specialty stores carry the best—look for plump, dark seeds. Smoked paprika? McCormick or Badia are reliable brands. The oil choice matters too—avocado oil has the highest smoke point, but vegetable oil works in a pinch. Fresh ginger should smell vibrant, not musty. If you can’t find fresh, use powdered at half the amount (but fresh is ideal).
No Sichuan peppercorns? Substitute with extra cayenne for heat, but you’ll lose that signature tingling. Running low on sesame oil? Toast a few sesame seeds in the oil instead—same flavor punch. The soy sauce can be swapped for coconut aminos if you’re avoiding soy. For a deeper umami, add 1 tsp miso paste to the oil while infusing. Chili flakes too spicy? Mix with a pinch of sugar to balance. And if you’re feeling adventurous, add a star anise pod to the oil for warmth (remove before serving).
This oil keeps for up to 1 month in the fridge, though it’ll likely disappear faster. Store it in a small glass jar with a tight seal—air exposure ruins the flavor. For extra shelf life, cover the surface with a thin layer of oil before sealing. Reheat gently before using—it thickens when cold. I like to drizzle it over ramen, roasted veggies, or even popcorn (trust me). Freeze in ice cube trays for single-use portions if you’re worried about spoilage.

Step-by-step instructions for black bean chilli oil
This smoky, umami-packed oil comes together in layers—start with the beans, then build flavor through toasting and infusing.
Prepare the Black Beans
Begin by soaking the 0.5 cup dried black beans overnight in plenty of water, or quick-soak them by covering with fresh water and bringing to a boil for 2 minutes, then letting them sit off heat for 1 hour. Drain and rinse thoroughly before using. The beans should be tender but still hold their shape—this ensures they infuse flavor without turning mushy in the oil.
Pat the drained beans completely dry with a clean kitchen towel. This step is crucial because any moisture will cause the oil to splutter dangerously when heated. Spread them on a baking sheet in a single layer and let them air-dry for 10 minutes. Now they're ready to toast and develop their deep, earthy flavor.
Toast the Aromatics and Spices
In a dry skillet over medium heat, lightly toast the 1 tsp Sichuan peppercorns for 1 minute until fragrant—you'll smell their citrusy, peppery aroma. Immediately transfer them to a small bowl and let them cool slightly. This toasting enhances their flavor without burning them.
In the same skillet, add the 4 cloves minced garlic cloves and toast for 30 seconds until golden and fragrant. Remove from heat and set aside. Next, toast the 1 tbsp smoked paprika and 2 tbsp red chili flakes together in the skillet for 1 minute, stirring constantly. The spices should smell rich and toasty—this is when they release their full potential. Remove from heat and combine with the garlic and Sichuan peppercorns.
Infuse the Oil with Flavor
Pour the 1 cup neutral oil into a clean saucepan and heat over low heat until it reaches 275°F—just below smoking point. Add the toasted spices, 1 tbsp finely grated fresh ginger, 1 tbsp soy sauce, and 0.5 tsp sea salt. Stir gently to distribute the spices evenly.
Remove the pan from heat and let it steep for 10 minutes. The oil will develop a deep red hue and an intense aroma—this is where the magic happens. After steeping, strain the oil through a fine-mesh sieve into a clean bowl, pressing gently on the solids to extract all the flavor. Discard the solids.
Finish with Sesame Oil
Return the strained oil to the saucepan and heat gently over low heat for 2 minutes. Stir in the 1 tbsp sesame oil and the 0.5 cup dried black beans. Keep the heat at low—just enough to warm the beans through without cooking them. The beans should soften slightly but remain intact, absorbing the oil's flavors.
Remove from heat and let the mixture cool to room temperature. The beans will continue to infuse the oil as they cool. Once fully cooled, transfer the black bean chilli oil to a clean, airtight jar. It will keep in the refrigerator for up to 2 weeks, or you can store it at room temperature for 1 week if you prefer a more liquid consistency.
Use and Store Properly
This chilli oil is versatile—drizzle it over noodles, stir it into soups, or use it as a bold dipping sauce for dumplings. For best results, let the oil come to room temperature before using it, as cold oil thickens and may separate slightly. If this happens, simply whisk it gently to re-emulsify.
If you notice any signs of spoilage—off smells, mold, or an unusual texture—discard the oil immediately. The smoky, umami-rich flavor of this chilli oil makes it a standout addition to any dish, so use it generously but judiciously to avoid overpowering your food.
Pro Tips For Making Black Bean Chilli Oil
- SOAK BEANS OVERNIGHT: Dried black beans are stubborn—skip the quick soak and let them sit in water for at least 8 hours (or overnight). I learned this the hard way: rushing them with a long simmer leaves them mealy instead of tender. Use twice the water volume and drain before cooking.
- CRACK PEPPERCORNS FIRST: Toast the Sichuan peppercorns whole in a dry pan until fragrant, then grind them just before adding to the oil. The aroma fades fast, and grinding too early dulls that signature numbing kick. Keep a mortar and pestle handy—it’s faster than a spice grinder for small batches.
- LOW-HEAT GARLIC: Add minced garlic to the oil when it’s just smoking, then immediately reduce to lowest heat. Garlic burns in seconds, and charred bits make the oil bitter. Stir constantly—yes, even if you’re impatient like me—and remove it as soon as it’s fragrant, not golden.
- STRAIN BEANS THOROUGHLY: After cooking, drain the beans twice in a fine-mesh sieve to remove every last bit of liquid. The oil’s texture suffers if even a drop of bean broth sneaks in—it’ll turn murky instead of glossy. Pat them dry with a towel if they’re clinging to moisture. Trust me, this step makes a real difference.
Perfect pairings for black bean chilli oil
Noodle Elevations
This chilli oil transforms simple noodles into a restaurant-worthy dish. Toss 8 ounces cooked ramen or fresh udon noodles with 1 tbsp black bean chilli oil per serving, then top with sliced green onions and a sprinkle of toasted sesame seeds.
The oil’s smoky depth clings to the noodles perfectly, creating a flavor bomb with every bite. 🍜
For extra richness, stir in 1 tbsp miso butter or a drizzle of spicy mayo after adding the chilli oil. The contrast of creamy and spicy takes this dish to the next level. I love serving it with a side of quick-pickled cucumbers to cut through the heat.
Crispy Veggie Drizzle
Roasted or air-fried vegetables become irresistible with this oil. Toss 1 lb Brussels sprouts or sweet potato wedges with 1 tbsp oil, 1 tsp maple syrup, and ½ tsp smoked paprika before roasting at 425°F for 20 minutes.
Finish with an extra drizzle of chilli oil right before serving. The caramelized edges and smoky oil make these veggies impossible to resist. 🥕
For a quick side, try blistered shishito peppers sautéed in 1 tbsp oil for 2 minutes, then finished with a splash of rice vinegar and a generous drizzle of chilli oil. The heat from the oil intensifies as it cools, making it perfect for dipping.
Dipping Sauce Magic
Use this oil as a bold dipping sauce for spring rolls, fried dumplings, or even crispy tofu. Mix 2 tbsp chilli oil with 1 tbsp soy sauce and 1 tsp rice vinegar for a perfect balance of spicy, salty, and tangy.
The oil’s texture makes it ideal for soaking up with every bite. 🍢
For a creamy twist, blend 2 tbsp chilli oil with ¼ cup Greek yogurt or vegan coconut yogurt until smooth. This works beautifully with crudité sticks or pita chips. The contrast of cool yogurt and fiery oil is pure flavor harmony.
Popcorn Upgrade
Yes, you read that right—this oil turns popcorn into a gourmet snack. Toss freshly popped popcorn with 1 tbsp chilli oil and 1 tsp brown sugar while still warm. The sugar caramelizes slightly, balancing the heat, while the oil adds a savory depth. It’s a crowd-pleaser that’s surprisingly addictive. 🍿
For a sweet-spicy combo, mix 1 tbsp chilli oil with 1 tbsp honey and a pinch of sea salt. Drizzle over cinnamon sugar tortilla chips or use it as a glaze for grilled pineapple slices. The contrast of sweet, spicy, and smoky is next-level.

Frequently asked questions
Can I use canned black beans instead of dried for this chilli oil?
While canned beans work in a pinch, dried beans create a much better texture and deeper flavor. Dried beans toast beautifully, adding a crispy element to the oil, while canned beans will make the oil more watery. If you must use canned, drain them thoroughly, pat them completely dry, and toast them until crispy before adding to the oil.
How do I adjust the heat level in this chilli oil?
Start by reducing the red chili flakes to 1 tbsp if you prefer mild heat, or increase to 3 tbsp for extra spice. For a smoky kick without heat, replace chili flakes with 1 tbsp smoked paprika. If you love tingling heat, add ½ tsp ground Sichuan peppercorn directly to the oil while infusing. Always taste as you go!
Why did my chilli oil turn cloudy or separate after refrigeration?
This happens when moisture gets into the oil or when the beans aren't properly dried before toasting. To fix it, simply whisk the oil gently at room temperature until smooth. For prevention, ensure your beans are completely dry before toasting, and store the oil in an airtight container with a thin layer of fresh oil on top to protect it from air exposure.
Can I make this chilli oil without Sichuan peppercorns?
If you can't find Sichuan peppercorns, substitute with ½ tsp cayenne pepper for heat or ½ tsp ground coriander for a citrusy note. For a similar tingling sensation, try adding ¼ tsp ground cardamom—it won't replicate the exact flavor but adds complexity. The oil will still be delicious without them!
How long can I keep this chilli oil at room temperature?
For best quality, store it in the refrigerator for up to 2 weeks. If you prefer room-temperature storage, keep it for no more than 1 week in a cool, dark place. The oil will last longer if you cover the surface with a thin layer of fresh oil before sealing. Always check for any off smells or mold before using—when in doubt, toss it out!
