For many years, my understanding of the term ‘confit’ was quite limited. Like most, I knew about the famous duck confit – a truly delicious French delicacy – likely picking up the term (and probably mispronouncing it) along the way. However, it wasn’t until I delved deeper into culinary arts that I became intimately familiar with this classic cooking technique and its incredible potential beyond just duck.

Food Safety Disclaimer: Homemade garlic confit and infused oils require careful handling due to the risk of botulism. Garlic is a low-acid ingredient, and when submerged in oil (an anaerobic environment) and stored at warm temperatures (room temperature), it can create conditions where Clostridium botulinum can thrive and produce a very serious toxin. For this reason, homemade garlic confit and garlic oil must always be immediately refrigerated after preparation. While food safety guidelines typically recommend consumption within 4 days, proper preparation and continuous refrigeration can extend its shelf life to several weeks. Please use your own discretion, but always be aware that improper storage of homemade garlic confit and garlic oil, especially at room temperature for prolonged periods, carries an inherent and significant food safety risk.
Understanding the Art of Confit: What Does It Mean?
My journey into the world of confit truly began during my time in culinary school, where I was introduced to a wealth of French cuisine and foundational cooking methods. Subsequently, working under a French-trained chef broadened my practical experience, and to “confit” became a regular part of my kitchen routine. We confited everything from aromatic garlic cloves to vibrant tomatoes, and much more.
For those unfamiliar, confit is a traditional French preservation technique characterized by slowly cooking an ingredient submerged in fat over very low heat for an extended period. This gentle cooking method ensures the food remains incredibly tender while becoming deeply infused with flavor. Historically, this method was used to preserve meats (like the classic duck confit, where cured duck legs are slow-cooked in their own fat) before refrigeration was commonplace. Today, it’s cherished for its ability to transform ingredients into rich, luxurious culinary components.
The fat used for confiting can vary; olive oil is popular for vegetables like garlic, while butter or animal fats are often used for other ingredients. It’s a method that stands in stark contrast to frying, which involves cooking food quickly in hot fat over high heat. Confit is all about patience and low temperatures, allowing the ingredient to slowly soften and absorb the surrounding fat’s flavor, resulting in a product that is meltingly tender and intensely savory.

The Delight of Garlic Confit
Among all the wonderful things I learned to confit during my professional culinary training, garlic confit has remained an enduring favorite. It’s remarkably simple yet yields incredible results: whole, peeled garlic cloves gently simmered in a generous amount of fragrant extra virgin olive oil for approximately 20 to 30 minutes, until they achieve an unparalleled tenderness.
While I personally find extra virgin olive oil imparts the most exquisite flavor, you can also experiment with other oils such as avocado oil or grapeseed oil, depending on your preference. The slow cooking process mellows the pungent bite of raw garlic, transforming the cloves into a sweet, rich, and incredibly soft texture, much like perfectly roasted garlic. They become so tender that they can be easily mashed or spread, releasing their concentrated, sweet garlic essence.
Unleashing Flavor: How to Use Garlic Confit and Its Infused Oil
The versatility of garlic confit is truly boundless, making it an indispensable secret weapon in any kitchen. Both the tender garlic cloves and the aromatic infused oil can elevate a myriad of dishes:
Ideas for Using Garlic Confit Cloves:
- Spreads and Dips: The cooked garlic cloves are incredibly soft and mashable. Spread them directly onto warm, crusty bread or toast for an instant garlic bread or bruschetta topping. Incorporate them into homemade hummus, aioli, or creamy dips for an intense burst of garlic flavor without the sharpness.
- Vegetable Enhancement: Mash them into Yukon Gold mashed potatoes for a rich, savory twist. Add them to roasted vegetables like roasted broccoli, asparagus, or carrots, providing a deep, sweet garlic undertone. They can also be tossed into sautéed greens or stirred into grain bowls.
- Main Dishes: Leave the cloves whole and scatter them over homemade pizza before baking. Integrate them into marinades, such as my easy chicken marinade, for an extra layer of flavor. Tuck them under the skin of a roast chicken or turkey for moist, flavorful meat.
- Pasta and Sauces: Mash the cloves into pasta sauces, stir them into risottos, or sauté them lightly with fresh vegetables for a quick and flavorful side dish.
Ideas for Using Garlic Infused Oil:
- Delicate Cooking: Use the flavorful garlic oil for light sautéing, infusing other ingredients with a subtle garlic essence.
- Finishing Oil: Drizzle it generously over freshly prepared soups, salads, grilled meats, or roasted vegetables just before serving.
- Salad Dressings: Incorporate the oil into your favorite vinaigrettes for a gourmet touch.
- Dipping: Serve it simply with a crusty baguette for dipping – it’s an incredibly satisfying appetizer.
For an added layer of aroma and flavor, consider infusing your garlic confit and oil with fresh herbs like rosemary or thyme, or even a pinch of dried chili flakes for a gentle warmth. Simply follow the instructions in the recipe below to incorporate these delightful additions!

Essential Storage: Does Garlic Confit Need to Be Refrigerated?
Yes, absolutely. Homemade garlic confit and any infused oils must be stored in the refrigerator without exception. This is crucial due to the potential risk of botulism. As mentioned previously, garlic is a low-acid food, and when covered in oil and kept at room temperature, it creates an anaerobic environment ideal for the growth of Clostridium botulinum bacteria, which produces a dangerous toxin. Following food safety guidelines, it’s generally recommended to consume homemade garlic confit within 4 days. However, when prepared and stored diligently in the refrigerator, it can often keep safely for several weeks. Always exercise your own judgment and prioritize food safety; improper storage significantly increases health risks.
When ready to use, simply spoon out the desired amount of garlic cloves or oil directly from the refrigerator into your pan for cooking. If you plan to use the oil for dipping or as a finishing drizzle, allowing it to come to room temperature for 30 minutes to an hour will improve its pourability and aromatic qualities, but always return any unused portion to the fridge promptly.
Can You Freeze Garlic Confit?
Yes, garlic confit can be frozen. While it stores remarkably well in the refrigerator for several weeks (and often up to a month if properly handled and continuously chilled), freezing offers an even longer-term storage solution if you make a large batch. To freeze, transfer the confit (cloves and oil) to an airtight, freezer-safe container. When ready to use, thaw it in the refrigerator overnight before incorporating it into your dishes. For optimal food safety, if you have any concerns, it’s best to use refrigerated confit within 3 to 4 days of preparation.

Crucial Food Safety Note: Garlic is a naturally low-acid food. Storing it improperly in oil (without oxygen) and at warm temperatures (room temperature) can lead to the production of a dangerous toxin that causes botulism. For this reason, homemade garlic confit and garlic oil must always be prepared and immediately stored in the refrigerator.
Per food safety guidelines, it is recommended to use them within 4 days of preparation. However, with consistent and proper refrigeration, they can often be safely stored for several weeks. Please always use your discretion and adhere to these guidelines strictly.
-
Carefully separate the heads of garlic into individual cloves using the palm of your hand. Trim the root end of each garlic clove with a sharp, small knife, then peel each clove, ensuring it remains intact. Discard any cloves that show signs of bruising or damage.
-
Place all the peeled garlic cloves into a small saucepan (a 2-quart size or larger is ideal). Pour the extra virgin olive oil over the garlic, ensuring the cloves are fully submerged. Place the saucepan over very low heat on your stove. As the oil gradually warms, you will observe small bubbles forming. These bubbles will slowly increase in size until the oil is gently simmering.
-
Continue to cook the garlic in the oil over this very low heat, stirring gently every few minutes, for 15 to 30 minutes. The exact cooking time will vary depending on the size of your garlic cloves, so adjust as necessary. The garlic cloves are ready when they are incredibly tender and cooked through, yet still maintain their shape and have not become heavily caramelized. You can test for doneness by piercing a clove with a long, sharp knife – it should offer little to no resistance.
-
Once cooked, remove the saucepan from the heat. If you’re using fresh herbs (like rosemary or thyme) or dried chiles, add them to the warm oil now to infuse. Carefully transfer the hot garlic confit and oil into a clean, heat-proof glass jar. Securely cover the jar with a tight-fitting lid and immediately refrigerate.
