What is Confit? Slow Fat Cooking Explained
Confit is one of the oldest preservation techniques in French cooking — and one of the gentlest ways to cook protein. The fat isn't there to fry; it's there to protect.
Definition
Confit (pronounced kon-FEE) comes from the French confire, meaning "to preserve." In cooking, it means submerging food completely in fat and cooking it at a low, controlled temperature for a long time. The fat acts as an even, gentle heat conductor that cooks the food through without browning it or raising the surface temperature high enough to cause protein contraction. The result is extraordinarily tender, with deep, rich flavor.
When to Use It
The classic application is duck confit — duck legs cured briefly in salt and herbs, then slow-cooked in rendered duck fat. The legs become silky-tender, stored in the fat (which preserves them), and crisped in a hot pan before serving. The technique also applies to chicken legs, pork shoulder pieces, and rabbit.
For home cooks without access to duck fat, garlic confit in olive oil is an accessible entry point — 40 cloves of garlic, submerged in olive oil, 45–60 minutes in a low oven. The result keeps in the fridge for weeks and transforms any dish it touches.
How to Do It (Garlic Confit)
- Peel an entire head (or several) of garlic cloves.
- Place in a small saucepan — the vessel should be just large enough that the garlic fits with room for oil.
- Cover completely with olive oil. Add a sprig of thyme or rosemary if desired.
- Heat on the stovetop to a bare simmer — tiny bubbles, not a boil. Or transfer to a 250°F (120°C) oven.
- Cook 40–60 minutes, until the garlic is completely tender and golden but not brown.
- Cool and store in the oil in an airtight jar in the fridge. Use within 2 weeks.
Common Mistakes
- Temperature too high. If the oil is bubbling vigorously, the garlic will fry and brown rather than confit. Small, lazy bubbles are what you want.
- Not enough fat. The food must be fully submerged. Any portion above the oil will cook unevenly or dry out.
- Skipping the cure for meat. For duck or pork, a 12–24 hour salt cure before the fat cook seasons the meat deeply and draws out excess moisture.

Frequently Asked Questions
- What is confit in cooking?
- A French technique where food is slow-cooked submerged in fat at low temperature (180–200°F), producing extremely tender results. Originally a preservation method.
- Is confit the same as frying?
- No. Frying uses high heat (350°F+) for quick browning. Confit uses low heat (under 200°F) for hours. The fat acts as a gentle, even heat conductor, not a crisping agent.
- Can you confit vegetables?
- Yes — garlic and tomato confit are very common. Garlic cloves in olive oil for 45–60 minutes at 200°F become sweet, spreadable, and mild.
- How long does confit take?
- Duck legs: 2–4 hours at 180–200°F. Garlic: 40–60 minutes at 200°F. The forgiving low temperature gives a wide window — it's hard to overcook a true confit.
