Duck Confit with Braised Cavolo Nero

Why This Works for Intermittent Fasting

Duck confit is about as calorie-dense and protein-rich as slow-cooked meat gets, with rendered duck fat providing a level of satiety that carries well through a long fasting window. Braised cavolo nero adds volume, bitterness, and micronutrients without a single gram of starch, rounding out the plate into a meal that feels indulgent while staying fully keto-compatible.

Ingredients

For the duck confit:

• 4 duck legs, skin on
• 2 tablespoons sea salt
• 4 garlic cloves, crushed
• 2 bay leaves
• 1 tablespoon fresh thyme leaves
• 1 teaspoon black peppercorns
• 500 ml (about 2 cups) rendered duck fat or ghee, enough to submerge the legs

For the braised cavolo nero:

• 1 large bunch cavolo nero (Tuscan kale), stems removed, leaves torn
• 3 tablespoons olive oil
• 3 garlic cloves, thinly sliced
• ¼ teaspoon chilli flakes (optional)
• 200 ml (about ¾ cup) chicken bone broth
• Sea salt and black pepper, to taste

Instructions

1. Salt and rest the duck. Rub the duck legs all over with sea salt, crushed garlic, thyme, and peppercorns. Place in a dish, cover, and refrigerate for at least 4 hours, or overnight for deeper flavour.

2. Rinse and dry. Wipe off the excess salt cure and pat the duck legs completely dry with paper towels.

3. Preheat the oven. Set the oven to 130°C / 265°F.

4. Submerge in fat. Place the duck legs in a deep, oven-safe pot or Dutch oven with the bay leaves. Melt the duck fat gently and pour over the legs until fully submerged.

5. Slow cook. Cover and cook in the oven for 2.5–3 hours, until the meat is tender and pulls away easily from the bone but still holds its shape.

6. Crisp the skin. Remove the legs from the fat and place skin-side up on a hot skillet or under a grill for 4–5 minutes, until the skin is deeply golden and crisp.

7. Braise the cavolo nero. While the duck rests, heat olive oil in a large pan over medium heat. Add the sliced garlic and chilli flakes and cook for 1 minute until fragrant. Add the cavolo nero and bone broth, cover, and simmer for 8–10 minutes until the greens are tender. Season with salt and pepper.

8. Serve. Plate the crisped duck confit over a bed of braised cavolo nero, spooning over a little of the pan liquid.

Nutrition Per Serving

Values are approximate and based on 4 servings; most of the confit fat is rendered off and not fully consumed.

Fasting Compatibility

Duck confit's density makes it well suited to breaking an extended fast or serving as the single meal on an OMAD day — the fat and protein combination is highly satiating with minimal insulin impact. It also works well as the closing meal of an 18:6 or 20:4 eating window.
