Ingredients for black bean chili oil

Nine simple ingredients transform into restaurant-quality chili oil with smoky depth and umami richness.

The olive oil is the foundation—high-quality extra-virgin makes all the difference. I always grab mine from Trader Joe's or Whole Foods for their consistent flavor profiles. Black beans should be drained and rinsed thoroughly to remove excess sodium, which can overpower the delicate balance of flavors. For the garlic, skin-on cloves add subtle sweetness when toasted lightly before mincing. The spices? Toast them in a dry pan for 30 seconds before adding to oil—this unlocks their full aromatic potential. Smoked paprika is non-negotiable here; Penzeys brand delivers the most authentic smoky flavor.

No smoked paprika? Substitute with 1 tbsp regular paprika plus 1/2 tsp liquid smoke, though the flavor won't be identical. Running low on black beans? Substitute with pinto beans or lentils, but reduce the amount to 3/4 cup to maintain proper oil-to-bean ratio. The lemon zest can be omitted if you prefer a more neutral profile, but I find it brightens the earthy flavors beautifully. For heat adjustment, start with less chili flakes—you can always add more later. The garlic quantity is precise; don't skimp here as it's the flavor anchor. If you're using pre-minced garlic from a jar, rinse it thoroughly to remove preservatives that may affect the oil's quality.

This chili oil develops deeper flavor when stored properly. Keep it in a dark glass bottle in the refrigerator for up to 2 weeks, where the flavors meld beautifully. For longer storage, freeze in ice cube trays—perfect portions for single use. The oil will solidify but returns to liquid state at room temperature. If the oil separates, simply shake vigorously before using. I always make a double batch; the extra freezes perfectly for future meals. The first use after refrigeration will be the most flavorful as the spices fully infuse over time.

Step-by-step instructions for black bean chili oil

Transform simple pantry staples into a bold, aromatic chili oil that elevates any dish.

Drain and rinse the 1 cup of black beans thoroughly under cold water, then pat them completely dry with paper towels. This ensures they crisp up properly rather than steaming in the oil. In a small skillet over medium heat, toast the 6 cloves of garlic cloves (skin-on) for 2-3 minutes until they're golden and fragrant. Remove and set aside to cool slightly.

Peeling garlic after toasting makes it easier, but I like to keep the skins on for extra flavor depth. The toasted garlic will add nutty, caramelized notes that balance the heat in the finished oil. Let the garlic cool completely before adding it to the oil to prevent burning.

In the same skillet (no need to clean it—the garlic flavor remains), combine the 1.5 tablespoons of dried chili flakes, 1.5 tablespoons of smoked paprika, and 1 tablespoon of ground cumin. Toast over medium-low heat for 1-2 minutes, stirring constantly, until the spices release their aroma and become deeply fragrant. Watch carefully—they'll darken quickly.

This step develops the spices' natural oils and intensifies their flavor. You're looking for a rich, earthy aroma that fills your kitchen. Remove the spices from heat immediately after toasting to prevent burning, which would make the oil bitter.

Transfer the 1.5 cups of extra-virgin olive oil to a heavy-bottomed saucepan and heat over low heat until it reaches 170°F (just below simmering). Add the toasted spices and black beans, stirring gently to combine. Keep the heat at a steady low—you want the oil to maintain this temperature without bubbling vigorously.

Simmer the mixture for 10-12 minutes, stirring occasionally, until the black beans turn crispy and the oil takes on a deep red hue. The beans should float to the top and develop a slightly charred appearance. Remove from heat immediately to prevent the oil from overheating, which could make it bitter.

Strain the infused oil through a fine-mesh sieve into a clean glass jar, pressing gently on the solids to extract every last drop of flavor. Discard the used beans and spices. While the oil is still warm, stir in the 1 teaspoon of sea salt and 1 teaspoon of lemon zest. The salt enhances all the flavors, while the lemon zest adds a bright, citrusy finish.

Let the chili oil cool to room temperature before sealing the jar. The flavors will meld further as it cools, creating a harmonious balance of smoky, spicy, and citrus notes. Store in a cool, dark place for up to 3 months, or refrigerate for up to 6 months to extend its shelf life.

Taste the chili oil immediately after cooling. If it needs more heat, add a pinch of chili flakes; if it needs more depth, stir in a tiny bit of smoked paprika. The lemon zest should brighten the flavors, but if it's too overpowering, you can reduce it slightly in future batches.

This chili oil is incredibly versatile—drizzle it over tacos, soups, or grilled meats, or use it as a marinade for proteins. The black beans add a subtle earthiness that rounds out the heat, while the toasted spices create a complex, smoky depth that makes this oil truly special.

Essential equipment for great black bean chili oil

Heavy-Bottomed Saucepan

This is my absolute essential tool for making chili oil—nothing else comes close. I use a 3-quart stainless steel saucepan from All-Clad, which distributes heat evenly and prevents scorching. The heavy base maintains a steady 170°F temperature without fluctuating, which is critical for proper infusion.

A lighter pan would cause hot spots, potentially burning the beans and making the oil bitter. 🔥

Fine-Mesh Sieve

A fine-mesh sieve (like the OXO Good Grips model) is non-negotiable for straining the oil. The tight weave captures even the smallest spices and crisped beans while allowing the oil to pass through smoothly.

I press the solids gently with a wooden spoon to extract every last drop of flavor—don’t skip this step! A regular colander won’t strain fine enough, leaving behind particles that can make the oil cloudy.

Glass Storage Jar

Store your chili oil in a dark amber glass jar (I recommend Ball Mason jars) to protect it from light, which degrades the oil’s quality over time. The dark glass preserves the vibrant red color and prevents oxidation.

Mason jars also create an airtight seal, keeping the oil fresh for up to 6 months in the fridge. Avoid clear glass—it lets in light that turns the oil rancid faster.

High-Quality Thermometer

A candy or deep-fry thermometer (like the Thermoworks Thermapen) is the secret to perfect chili oil. You need precise control at 170°F—any hotter and the oil risks burning, any cooler and the flavors won’t infuse properly.

I clip the thermometer to the saucepan’s handle so I can monitor the temperature without lifting the lid, which would release steam and disrupt the infusion process. 🌡️

Small Skillet for Toasting

A 10-inch cast iron skillet (like Lodge’s) is ideal for toasting the garlic and spices. Cast iron retains heat exceptionally well, ensuring even toasting without scorching. I heat it over medium-low to prevent burning the spices, which would make the oil taste bitter.

The skillet’s weight also helps distribute heat evenly, so every clove of garlic and pinch of spice gets properly toasted.

Wooden Spoon

A heat-resistant wooden spoon (I use Oxo’s with a silicone handle) is perfect for stirring the oil without scratching the pan or introducing metal flavors. Wood is gentle on the saucepan and won’t conduct heat away like metal spoons.

Plus, it’s easy to clean—just soak it in warm, soapy water after use. Avoid plastic spoons, which can melt if they touch hot oil.
