Duck Confit (Carnivore Adaptation)
By Carl Henderson · Retired French Chef · Updated 2026-05-08
Duck legs salt-cured 24 hours, then slow-cooked submerged in duck fat at 200°F for 2.5 hours. The French preservation classic, no thyme or bay.
Carnivore duck confit is 4 duck legs salt-cured for 24 hours with 1.5 tablespoons of coarse salt, then slow-cooked completely submerged in 4 cups of warmed duck fat at 200°F for 2.5 to 3 hours until the meat falls off the bone. Salt is the only seasoning — no thyme, no bay leaves, no garlic, no peppercorns. Duck confit is one of the iconic French preservation methods (the cured-and-slow-cooked legs traditionally store for months in their own fat). The strict carnivore version drops the herbs and aromatics. A single duck-leg serving (about 6 ounces of meat off the bone) delivers 30g protein, 20g fat, and 320 calories. Duck legs cost $7 to $11 per pound; a 4-leg batch costs $20 to $35. The 4-cup duck fat reservoir is reusable indefinitely — strain after each batch and refrigerate. Crisp the cooked legs in a hot skillet before serving for the iconic crisp-skin-with-falling-apart-meat eating experience.

Instructions
- 1
24 hours before cooking: rub duck legs with 1.5 tbsp coarse salt, working it into the skin and around the bone. Place in a non-reactive container, cover, refrigerate 24 hours to dry-cure.
- 2
After curing, rinse legs briefly under cold water and pat completely dry with paper towels.
- 3
Preheat oven to 200°F. Warm the 4 cups duck fat in a Dutch oven or heavy ovenproof pot until melted and warm but not hot.
- 4
Submerge duck legs completely in the warm fat — they should be entirely covered.
- 5
Cover with the lid (or foil if no lid) and place in the 200°F oven.
- 6
Cook for 2.5 to 3 hours. The meat is done when a fork slides through with no resistance and the bone wiggles freely.
- 7
Lift legs out with tongs onto a paper-towel-lined plate. Strain the cooled fat back into a storage jar (reusable for future confit batches).
- 8
To serve: crisp the legs in a hot dry cast iron skillet for 4 to 5 minutes per side until skin is shatteringly crispy. Serve immediately.

Frequently Asked Questions
Why cook duck legs in duck fat?
Submerging in fat eliminates contact with air during the long slow cook, preserving the meat from oxidation and browning. Fat is also a more efficient heat-conduction medium than water at low temperatures, producing more uniform cooking. Traditional preservation: confit legs stored in their own fat at room temperature for 6 months or longer (the cure plus the fat seal kept them safe). Modern food safety recommends refrigeration; the technique still produces remarkably tender meat.
Where do I get 4 cups of duck fat?
Three sources. Best: render it yourself from whole roast ducks (one duck yields 1 to 1.5 cups; you'll need 3 ducks worth for one confit batch). Save fat from previous duck dinners over time. Second: buy duck fat at Whole Foods or specialty butchers ($12 to $18 per cup, $48 to $72 for the 4 cups). Third: substitute beef tallow or pork lard (not traditional but functional) — $6 to $10 for 4 cups. Tallow-based confit tastes different but the technique works.
How long does confit keep?
Traditional confit (legs stored submerged in their own fat at room temperature) keeps 6 months. Modern food-safety guidelines recommend refrigeration at 40°F: confit legs in their fat keep 1 month. Without the fat (cooked and removed): 5 days refrigerated, 3 months vacuum-sealed and frozen. The eating experience improves over the first week as the salt and fat continue to penetrate the meat. Crisping the skin is the final step regardless of storage time.
