Steps
Before you start
- Measure all ingredients ahead of time
- Have a heat-safe jar or glass bowl ready to hold the finished oil
- Use fresh dried chiles de árbol with no mold or musty smell
Air-fry the chilesOven 350°F / 175°C
- Place the whole dried chiles de árbol (stems and seeds removed) in a single layer in the air fryer basket.
- Set the air fryer to 350°F (175°C) and cook for 4–5 minutes, shaking the basket halfway through, until the chiles are deeply fragrant, darkened, and slightly crispy but not burned.
- They will continue to crisp as they cool.
- Watch carefully—they can scorch quickly.

Ready when: Chiles are deeply fragrant, darkened, and crispy but not blackened; they crumble easily when cool
Tip: Do not overcook—burnt chiles taste acrid. If using very thin chiles, reduce time to 3–4 minutes.
Toast the aromaticsOven 325°F / 165°C
- Add the unpeeled garlic cloves and cumin seeds to the air fryer basket with the hot chiles.
- Return to the air fryer at 325°F (163°C) for 3–4 minutes, shaking once halfway through, until the garlic is lightly golden and the cumin is fragrant.
- Do not let them burn.

Ready when: Garlic is golden on the outside, cumin seeds are fragrant and slightly darkened
Tip: Lower the heat slightly to prevent the chiles from burning further; garlic and cumin toast faster than chiles.
Cool the spices
- Transfer the chiles, garlic, and cumin to a clean, dry heat-safe glass jar or bowl.
- Let them cool to room temperature, about 10 minutes.
- This stops the cooking and allows the residual heat to gently infuse the oil.

Ready when: The jar is cool to the touch
Tip: Cooling the spices in the jar they will be infused in saves a transfer step.
Warm the olive oil
- In a small saucepan, heat the olive oil over medium-low heat until it is warm to the touch (around 120–130°F / 49–54°C), about 2–3 minutes.
- It should be hot enough to carry the flavors of the toasted spices but not so hot that it will cook them further.
- Do not let it smoke.

Ready when: Oil is warm to the touch, beginning to shimmer slightly, no smoke
Tip: Too-hot oil will over-toast the spices and make the oil bitter. Too-cool oil will not extract the full flavor.
Infuse the oil
- Pour the warm oil over the toasted chiles, garlic, cumin, and Mexican oregano in the jar.
- Stir gently with a small spoon or wooden skewer to distribute the spices.
- Let the mixture steep at room temperature for 15–20 minutes, stirring occasionally, until the oil is deeply red and fragrant.

Ready when: Oil is deeply red-orange, fragrant, and flavors have melded
Tip: Stir a few times to ensure even flavor distribution and to prevent the aromatics from settling to the bottom too quickly.
Strain and season
- Set a fine-mesh strainer or cheesecloth over a clean jar.
- Pour the chile oil through the strainer, pressing gently on the solids with the back of a spoon to extract any remaining oil (do not squeeze hard or you will crush the chiles and make the oil cloudy).
- Discard the solids.
- Stir in the sea salt and taste.
- Add more salt if needed.

Ready when: Oil is clear and deeply colored, free of debris, well-seasoned
Tip: Gentle pressing extracts flavor without making the oil cloudy. If you prefer a rustic, textured oil with visible chile flakes, skip straining and leave the solids in.

Tips
- Air-frying the spices before infusing creates a deeper, more toasted flavor than raw spices steeped in cold oil. The dry heat concentrates and awakens the essential oils in each ingredient.
- Use this chile oil to finish soups, drizzle over fried eggs, dollop on avocado toast, or dress grain bowls, roasted vegetables, or fresh cheeses. A little goes a long way.
- If you prefer a milder oil, remove the chile seeds before air-frying; if you want it hotter, skip that step or add an extra dried chile.
- For a chunkier, rustic oil, leave the toasted spices in the jar and simply shake before each use instead of straining. This shortens storage time to about 1 week but gives a more textured, rustic appearance.
Storage & reheating
Store in a sealed glass jar or bottle at room temperature, away from direct heat and light, for up to 2 weeks. For longer storage, keep refrigerated for up to 1 month. The oil will solidify slightly when cold but will return to liquid at room temperature. Do not freeze. Before each use, give the bottle a gentle shake or stir to combine the oil and any settled spices.
Substitutions
- dried chiles de árbol, stems removed → dried guajillo or chilhuacle negro chiles. Guajillos are milder and fruitier; chilhuacles are earthier. Both work well but will change the heat level and flavor profile. Adjust the amount to taste.
- dried Mexican oregano → dried marjoram or Mediterranean oregano. Use the same amount, though marjoram is more delicate and oregano less herbaceous than Mexican oregano. The oil will be slightly less complex.
- extra-virgin olive oil → avocado oil or high-heat vegetable oil. Use avocado oil for a milder, buttery taste; vegetable oil for a neutral base. Both handle infusion well, though they lack olive oil's richness.
- cumin seeds → caraway seeds or fennel seeds. Both add warmth and complexity but with different aromatic profiles. Use the same amount, though caraway is more assertive.
