Garlic Herb Infused Oil

The secret to this oil is patience. By keeping the heat low, you avoid burning the garlic, which would turn the oil bitter and ruin the effort.

Before you start

Watch the temperature closely.

This process is about extraction, not frying. If the oil begins to bubble vigorously, pull it off the heat immediately.

  • Small saucepan
  • Thermometer (optional)
  • Fine mesh sieve
  • Glass storage jar
Ingredients

What goes in.

  • 1 cupNeutral oil, such as grapeseed or avocado
  • 4 clovesGarlic, smashed
  • 3 sprigsFresh rosemary or thyme
  • 1 tspWhole black peppercorns
The key technique

Controlled Extraction

Maintain the oil temperature between 180°F and 200°F. This allows the essential oils in the herbs and garlic to release into the base oil without degrading their color or structure.

Step by step

The method.

  1. Combine ingredients

    Place the oil, smashed garlic, herbs, and peppercorns into the saucepan over the lowest possible heat setting.

  2. Steep the aromatics

    Allow the mixture to warm for 15 to 20 minutes. You are looking for very small, lazy bubbles forming around the garlic.

  3. Cool and strain

    Remove from heat and let it sit until it reaches room temperature. Strain the solids through a sieve into a clean jar.

Variations

Other turns to take.

Chili Garlic

Add two dried red chilies to the oil during the steeping process for a noticeable heat.

Lemon Herb

Add a wide strip of lemon zest once you remove the pan from the heat, letting it steep during the cooling phase.

Tips & troubleshooting

When it doesn't go to plan.

Tip

Discard the used garlic and herbs after straining; they will have given up all their flavor to the oil.

Tip

Store the finished oil in a dark cabinet to preserve its flavor and shelf life.

Tip

If the oil becomes cloudy in the refrigerator, it will clear up as it returns to room temperature.

Questions

The ones that keep coming up.

How long will this oil keep?

Store it in an airtight container in the refrigerator and use it within two weeks for the brightest flavor.

Can I leave the garlic in the bottle?

It is safer to strain it out. Removing the solids prevents unwanted fermentation and keeps the oil clean and clear.
