How To Make Garlic Infused Olive Oil?
Written by: Berk Bahceci
You can make garlic infused olive oil at home in about twenty minutes. You should also know why we, as producers, don't make ours that way, and why the homemade version comes with a real safety rule most recipes skip.
The quick method
Here's the warm-infusion method that works reliably at home:
1. Start with a good extra virgin olive oil. The infusion only tastes as good as the base: a flat, refined oil gives you flat, refined garlic oil. We'd use our Early Harvest.
2. Peel 4–6 fresh garlic cloves per cup of oil and crush them lightly: you want them cracked open, not minced.
3. Combine garlic and oil in a small saucepan over the lowest heat your stove will hold. You're aiming for a bare murmur, around 180–200°F, never a fry. Hold it there for 15–20 minutes until the cloves are pale gold and the kitchen smells like the inside of a good restaurant.
4. Cool completely, strain out every piece of garlic, and pour into a clean, airtight bottle.
The heat does two jobs: it speeds the flavor transfer, and it matters for safety, which is the part most recipes gloss over.
The botulism part, read this before you make it
Garlic is a root vegetable, and its surface can carry Clostridium botulinum spores. Those spores are harmless in air, but sealed in oil, a moist, oxygen-free environment, they can produce botulinum toxin. This isn't scaremongering; it's why the FDA and university extension services all publish the same rules for homemade garlic oil:
Keep it refrigerated, always. Never leave homemade garlic oil at room temperature.
Use it within 3–4 days if made with fresh garlic. That's the official window, shorter than almost anyone expects.
Strain out the solids. Garlic pieces left in the bottle are where the risk concentrates.
When in doubt, throw it out. Botulinum toxin has no smell and no taste.
If you want a version that lasts longer, the tested approach is acidifying the garlic first (a citric-acid soak, per university extension methods), or buying a professionally made bottle, where the infusion method removes the water-activity problem entirely. That's not a sales line; it's the actual food-science reason infused oils are a category producers exist for.
How we make ours instead
Our Garlic Infused Olive Oil starts with the same early-harvest extra virgin we bottle on its own. Instead of steeping raw cloves, we infuse with organic, non-GMO garlic extract oil, no water content, no heat damage to the base oil, no botulism math, and a garlic flavor that stays vivid for the life of the bottle instead of fading in a week. It's shelf-stable and tastes like garlic and like olive oil, which is rarer than it sounds.
What to do with it
However you get your bottle, the use cases are the same, and they're daily: dragged through with warm bread (see the bread dipping guide), the fastest pasta aglio e olio shortcut that exists, over roasted vegetables and potatoes, whisked into salad dressings, brushed on pizza crust, finishing a fried egg. Once it's on the counter you'll stop measuring garlic for half your cooking.
FAQ
How long does homemade garlic infused olive oil last?
Refrigerated, 3–4 days: that's the FDA-aligned guidance for fresh garlic in oil. Commercially infused oils like ours are shelf-stable because they're made without raw garlic's water content.
Can you get botulism from garlic infused olive oil?
From improperly stored homemade versions, yes: it's the classic risk scenario. Refrigerate, use within days, strain out solids. Commercial infusions made with extract oil don't carry the same risk.
Do you have to heat the oil to infuse it?
No, cold infusion works, but it's slower and the safety window is the same or shorter. Gentle heat (under 200°F) speeds flavor transfer without frying the garlic.
Can I use the leftover garlic cloves?
Yes, use the strained, oil-confited cloves within a day or two: mash onto bread, into dressings, or into mashed potatoes. Refrigerate them too.
What's the best olive oil to use for infusing?
A real extra virgin with a recent harvest date. The infusion amplifies whatever the base oil is, here's how to tell a real bottle from a fake one.
