Ingredients for black bean chilli oil
Nine essential ingredients blend into a restaurant-quality condiment with umami depth and smoky heat.
| Ingredient | Amount | Notes |
|---|---|---|
| Dried Black Beans 🌱 | ½ cup | Rinsed and soaked overnight |
| Chilli Flakes 🌶️ | 2 tbsp | Adjust for heat preference |
| Garlic Cloves 🧄 | 4 cloves | Peeled and roughly chopped |
| Apple Cider Vinegar 🍏 | 2 tbsp | For tangy brightness |
| Extra-Virgin Olive Oil 🫒 | 1 ½ cups | High-quality, fruity variety |
| Smoked Paprika 🌶️ | 1 tbsp | For smoky depth |
| Ground Cumin 🌿 | ½ tbsp | Toasted for enhanced aroma |
| Sea Salt 🧂 | ½ tsp | Fine grain preferred |
| Fresh Ginger 🌿 | 1 tbsp | Finely grated, fresh |
| Sesame Oil 🫒 | 1 tbsp | For nutty finish (optional) |
The black beans form the emulsifying base, so choose high-quality dried beans—avoid pre-cooked or canned, as they won’t blend smoothly. Trader Joe’s and bulk spice shops carry excellent options. Soak the beans overnight in double their volume of water to ensure they soften completely. The chilli flakes should be bright red and aromatic—if they smell stale, replace them. For garlic, fresh cloves are non-negotiable; pre-minced garlic lacks the depth needed here. The olive oil must be extra-virgin—cheaper varieties will compromise the emulsion’s stability and flavor.
No chilli flakes? Crushed red pepper flakes or cayenne work in a pinch, though the texture will differ slightly. Substitute apple cider vinegar with rice vinegar or lemon juice for a brighter acidity. If you’re avoiding sesame oil, toasted sesame seeds can be ground into the blend instead. For extra depth, add a pinch of white pepper alongside the sea salt. The smoked paprika can be swapped for regular paprika, though the smoky profile will be less pronounced. Always strain the blended beans through a fine-mesh sieve to achieve that signature silky texture—no pulp means no separation.
Store the chilli oil in a sterilized glass jar with a tight-sealing lid, submerged in the refrigerator. This preserves its vibrant color and prevents oxidation for up to four weeks. For longer storage, transfer to an airtight container and freeze for up to three months. Shake gently before each use, as the emulsion may settle slightly. The flavor intensifies over time, so make a fresh batch when the heat starts to fade. Use it sparingly at first—just a drizzle—then adjust to taste. Its versatility makes it a pantry staple worth repeating.

Step-by-step instructions for black bean chilli oil
Here's the method for creating a rich, complex chilli oil with smoky depth and umami heat.
Toast the Dried Black Beans and Spices
In a dry skillet over medium heat, add the 0.5 cup dried black beans and toast them for 3-4 minutes until they darken slightly and release an aromatic fragrance. This process enhances their nutty flavor and removes any potential bitterness. Remove the beans and set them aside temporarily.
In the same skillet, add the 4 cloves garlic cloves, 1 tbsp smoked paprika, and 0.5 tbsp ground cumin. Toast for another 1-2 minutes until the garlic turns golden and the spices become fragrant. Be careful not to burn the garlic—it should be golden, not brown. This step develops the aromatic foundation of your chilli oil.
Infuse the Olive Oil with Aromatics
Transfer the toasted black beans, garlic, and spices to a blender or food processor. Add the 1.5 cups extra-virgin olive oil, 2 tbsp apple cider vinegar, and 1 tbsp finely grated fresh ginger. Blend on high speed for 30-45 seconds until the mixture becomes smooth and emulsified. The oil should take on a deep, reddish hue from the black beans and spices.
This blending process ensures that all the flavors are evenly distributed throughout the oil. The vinegar adds a bright acidity that balances the richness of the olive oil, while the ginger contributes a subtle warmth. The texture should be silky smooth with no visible particles.
Cook the Chilli Oil to Perfection
Pour the blended mixture into a heavy-bottomed saucepan and place it over low heat. Stir in the 2 tbsp chilli flakes and 0.5 tsp sea salt, then cook for 8-10 minutes until the mixture reaches 160°F. This gentle cooking process allows the flavors to meld together while preventing the oil from overheating and losing its delicate balance.
You'll notice the oil develop a rich, complex aroma with notes of smokiness, heat, and umami. The chilli flakes should be evenly distributed, and the oil should have a glossy sheen. If you prefer a more intense heat, you can increase the chilli flakes slightly, but start with the given amount to gauge your preference.
Finish with Sesame Oil and Strain
Remove the saucepan from heat and stir in the 1 tbsp sesame oil. This final touch adds a nutty depth and enhances the overall complexity of the chilli oil. Let the mixture cool for 5 minutes to allow the flavors to settle.
Line a fine-mesh strainer with cheesecloth or a coffee filter and strain the chilli oil into a clean, airtight jar. Press gently on the solids to extract as much oil as possible, but avoid forcing the liquid through—this ensures a smooth, particle-free oil. The resulting chilli oil should have a vibrant red hue and a rich, aromatic scent that promises bold flavor.
Pro Tips For Making Black Bean Chilli Oil
- SOAK BEANS OVERNIGHT: DESCRIPTION: I learned this the hard way—rushing the soak means gummy beans that never fully break down. Use 4 cups water per cup of dried black beans, let them sit 8+ hours (or quick-soak: 2 hours in boiling water). The longer they soak, the smoother your oil will be in the end.
- TOAST CHILLI FLAKES FIRST: DESCRIPTION: Skip this, and your oil will taste flat. Dry-toast the chilli flakes in a separate pan over medium-low for 30 seconds—just until they smell deep and smoky. Then add them to the garlic and oil. The aroma change is night and day.
- LOW AND SLOW FOR OIL: DESCRIPTION: Cranking the heat to infuse the oil faster burns the garlic before the beans soften. Simmer the oil on the lowest possible heat—just above a bare bubble—while the beans cook. Patience here keeps the oil golden, not bitter.
- ACID AT THE END: DESCRIPTION: My grandmother swore by this, and she was right: add the apple cider vinegar only in the last 2 minutes of cooking. It brightens the oil without making the garlic taste raw. (Yes, even if you’re impatient like me.)
Storing and reheating your black bean chilli oil
Fridge Storage Secrets
Store your black bean chilli oil in a sterilized glass jar with a tight-sealing lid, keeping it submerged in the fridge at 40°F or below. The glass preserves its vibrant color and prevents oxidation, while the airtight seal locks in flavor for up to four weeks.
I always use amber glass jars—they block light that can degrade the oil’s quality over time. 🌱
Before sealing, let the oil cool completely to room temperature. This prevents condensation inside the jar, which can dilute flavors. Label your jar with the date to track freshness—trust me, you’ll want to make a fresh batch when the heat starts to fade after a month.
Freezer Preservation
For longer storage, transfer the chilli oil to an airtight freezer-safe container or quart-sized freezer bag, leaving 1 inch of headspace for expansion. Freeze for up to three months without significant quality loss. When ready to use, thaw in the fridge overnight—never at room temperature to prevent bacterial growth.
I recommend dividing the oil into smaller portions before freezing. This way, you can thaw just what you need without dealing with a giant block of oil. The texture may thicken slightly after freezing, but a quick shake restores its silky consistency. 💫
Reheating for Maximum Flavor
There’s no need to reheat black bean chilli oil—it’s best served at room temperature or slightly chilled. However, if you’ve stored it in the freezer, let it sit at room temperature for 15-20 minutes before using.
The flavors will be more vibrant and balanced. Never microwave it, as heat can destroy the delicate emulsion and alter the flavor profile.
If your oil separates slightly after refrigeration, simply shake the jar vigorously for 10-15 seconds before using. The black bean base creates a naturally stable emulsion, so separation is minimal compared to traditional chilli oils. A quick shake brings everything back together beautifully. ✨
Reviving Stale Oil
If your chilli oil loses some of its punch after a few weeks, don’t toss it! Add ½ tsp fresh garlic powder and ½ tsp smoked paprika to a small portion, then blend briefly to revive the flavors.
This trick works like a charm for bringing back depth without starting from scratch.
For extra heat, stir in ¼ tsp cayenne pepper or a pinch of freshly cracked black pepper. The acidity from a splash of apple cider vinegar can also brighten up the flavor profile. Just a few drops can make all the difference! 🔥

Frequently asked questions
Why do I need to toast the black beans?
Toasting the black beans enhances their natural nutty flavor and removes any potential bitterness. This step also helps create a smoother, more stable emulsion when blended with oil. Skipping it can leave your chilli oil tasting flat or slightly bitter.
Can I use canned black beans instead of dried?
No—canned beans won't work because they're pre-cooked and too soft to create the proper emulsion. The dried beans' texture is essential for binding the oil and spices. If you're short on time, soak canned beans overnight to mimic dried beans' structure, but results may vary.
How do I adjust the heat level?
Start with the 2 tbsp chilli flakes as written, then adjust to taste. For milder heat, reduce to 1 tbsp; for extra spice, add up to 3 tbsp. For a smoky kick without extra heat, increase the smoked paprika to 1.5 tbsp. Always taste before straining!
Will this chilli oil separate if I don't strain it properly?
Yes—proper straining is critical. Use a fine-mesh sieve lined with cheesecloth to remove all bean pulp. Even tiny particles can cause separation over time. If it does separate, just shake the jar vigorously before using. The black bean base makes this emulsion more stable than traditional chilli oils.
What are the best ways to use this chilli oil?
Drizzle it over steamed rice, noodles, or tofu stir-fries for instant flavor. Use it as a marinade for veggies or proteins, or mix into dressings. It's also perfect for finishing soups or ramen bowls. Start with ½ tsp and adjust to taste—this oil packs serious umami punch!
