Making Infused Oils
Infused oil is achieved by gently warming aromatics in a neutral fat or submerging them in cold oil over time, effectively drawing out essential oils and compounds to flavor the base. The most reliable method for home storage is the quick-infusion heat method, which ensures safety by fully incorporating flavors into the oil before straining.
Dry ingredients are your best friend
Any moisture remaining on herbs, garlic, or peppers creates an environment where bacteria can thrive. Ensure everything you add is bone-dry before it touches the oil.
- Small heavy-bottomed saucepan
- Fine-mesh sieve
- Cheesecloth
- Sterilized glass bottle with a tight seal
What goes in.
- 2 cupsNeutral oil (grapeseed, canola, or light olive oil)
- 1 cupDried herbs, dried chilies, or dehydrated garlic cloves
The simmer-and-rest
Keep the oil at a low, consistent temperature—never above 200°F (95°C). You are looking for a lazy bubble around the aromatics, not a fry.
The method.
Prepare the aromatics
Ensure your herbs or garlic are completely dried. If using fresh herbs, dehydrate them in a low oven first until brittle.
Combine
Place the oil and your chosen aromatics into the saucepan over the lowest heat setting your stove allows.
Infuse
Let the mixture barely simmer for 30 to 45 minutes. Watch the aromatics; garlic should turn golden, not dark brown. Dark brown means burnt and bitter.
Cool and strain
Remove from heat and let it cool completely in the pan. Line a sieve with cheesecloth and pour the oil through into your sterilized bottle.
Store
Seal the bottle and keep it in a cool, dark cupboard. If the oil becomes cloudy or smells off, discard it immediately.
Other turns to take.
Chili Oil
Use dried bird's eye chilies or crushed red pepper flakes.
Garlic-Rosemary Oil
Combine dried rosemary needles with toasted dried garlic slices.
When it doesn't go to plan.
Always use dried aromatics to eliminate water content.
Label your bottle with the date; infused oils have a shorter shelf life than standard cooking oils.
Small batches are better; make only what you can use within three weeks.

Can I use fresh herbs?
It is strongly discouraged for home cooks. Fresh herbs contain water that causes spoilage and increases the risk of dangerous bacteria developing in the oil.
How do I know if the oil has gone bad?
Trust your nose. If it smells rancid, metallic, or off in any way, pour it out.
