Cook garlic and oil on the stove for extra intense flavors, or simply toss them in a jar and let them infuse for a few days. Buon appetito!

Ingredients

Stovetop Garlic Oil

4 cloves of fresh garlic
¹⁄₂ cup (120 ml) of olive oil

No-Cook Garlic Oil

8 cloves of fresh garlic
2 cups (470 ml) of olive oil

Method 1 of 2:

Making Stovetop Garlic Oil

1
Crush 4 cloves of garlic directly into a saucepan and pour in the olive oil. Squeeze the cloves of garlic through a garlic press directly into the pan. Stir the garlic and the ¹⁄₂ cup (120 ml) of olive oil together so the garlic is evenly distributed in the pan.^{[1]

- You don’t need to peel the garlic before putting it in the press. The peel will stay in the press while you squeeze it.
- Substitute other oils for the olive oil based on your personal preferences.
How to Choose a Type of Oil

If you’re only using it for cooking, go with a neutral oil that can handle high temperatures, like canola, vegetable, or grapeseed oil.^{[2]

For a heart-healthy oil, choose extra-virgin olive oil or avocado oil, thanks to their monounsaturated fat content.

If you want a unique flavor, try sesame oil. It’s one of the strongest oils and you’ll get a nice, nutty flavor.

Heat the mixture over medium low heat for 3 to 5 minutes. The heat helps infuse the flavor of the garlic into the oil. Cook the mixture, stirring it occasionally, until the garlic is light brown and slightly crispy.^{[3]

- Don’t let the oil boil. When oil gets too hot, it loses some of its flavor and integrity. A light simmer is enough.^{[4]

- Avoid overcooking the garlic. If it’s a very dark color, you’ve cooked it too long and the oil will be bitter.

Remove the pan from the heat and pour the mixture into a container. Let the mixture cool completely before placing the lid on the airtight container and sealing it tightly. This prevents excess moisture from gathering in the container and spoiling the oil.^{[5]

- If you don’t want tiny bits of garlic in your oil, you can strain it through a colander or sieve as you pour the mixture into the container.
- Leaving the garlic pieces in the oil will create a stronger flavor as it continues to infuse over time.
4
Keep the oil in the refrigerator for up to 5 days. You can shake the container every so often to mix up the flavors. Throw the oil away after 5 days if you haven’t used it, just to be safe and avoid ingesting dangerous bacteria.^{[6]

- Never keep garlic oil at room temperature. It can cause botulism, which is a sometimes fatal form of food poisoning most often found in preserved food.
- Freeze the garlic oil for up to 1 year if you want it to last longer.

Method 2

Method 2 of 2:

Making No-Cook Garlic Oil

1
Crush 8 cloves of garlic with the back of a knife. Place the cloves on a plastic, ceramic, or glass cutting board. Then, use the palm of your hand to press the flat end of a wide knife blade onto each clove. Push hard enough to crush the clove and split the skin.^{[7]

- Leave the peels on while you crush the garlic. Otherwise, the cloves will be too slippery and you could cut yourself with the knife.
- Avoid using a wooden cutting board. It will absorb some of the garlic’s flavor.^{[8]

2
Remove and discard the garlic peel. The skin should come off the cloves very easily once they’re crushed. Throw the peel in the trash or put it in a compost bin.^{[9]

- If the peel is tough to remove, you may need to crush the garlic a little more.
3
Combine the crushed garlic and 2 cups (470 ml) of olive oil in a jar. Any glass jar with an airtight lid will work. After screwing the lid on the jar, shake it a few times to mix up the garlic and the oil.^{[10]

- You can substitute any type of oil, like avocado oil or grapeseed oil, for the olive oil, depending on the flavor you want or what you have in the pantry.
- Add spices or herbs for different flavor options.

Store the jar in the refrigerator for 2 to 5 days. This gives it enough time for the flavors to blend thoroughly. Make sure the jar is sealed tightly while it’s in the fridge to keep the oil fresh.^{[11]

- If you try to use the oil before 2 days, the flavors won’t be as strong.^{[12]

- Throw the oil away after 5 days or you increase your risk of getting botulism, which is a type of food poisoning that comes from canned or preserved foods and can be deadly.
- You can also freeze the garlic oil for up to 1 year.
