Duck Leg Confit on Cassoulet: A Dry Brine Recipe That Does the Work for You

A few minutes of prep the night before, a few more to get it in the oven and hours later a few more to put it on a plate. Easiest duck confit recipe in the world.

 

If you've never made duck leg confit at home, here's the thing — it's way less fussy than it sounds. Most people think you need a pile of duck fat in reserve, but in this recipe you need NONE!  You're basically just salting duck legs with a dry brine, tossing them in a pot, and letting your oven do the heavy lifting while you go about your day. Come back a few hours later and you've got fall-apart tender meat with rich, crispy skin sitting on top of a rustic cassoulet loaded with white beans, bacon, and aromatics.

This recipe makes more than double the cassoulet that you need for a four-person dinner, but it freezes beautifully — giving you a serious leg up the next time you have duck legs kicking around. Think of it as a future-you gift.

Why Dry Brine Your Duck Legs?

A dry brine does two critical jobs here. First, it seasons the meat all the way through — not just the surface. Second, it pulls moisture from the skin so that when you hit it under the broiler at the end, you get that shatteringly crispy finish that makes duck confit legendary. A liberal coat of RP Dry Brines DUCK seasoning salt the night before is all it takes — their blend is built to brine deeply and flavour boldly without any extra effort on your part.

What You'll Need

• 4 duck legs (RP Dry Brines seasoning salt, applied liberally)
• 1 whole head of garlic
• 1 knob fresh ginger, halved
• 1 large dried chili
• 2 cups white beans (soaked overnight)
• 1 onion, diced
• 2 carrots, diced
• 2 stalks celery, diced
• 4 cloves garlic, minced
• 1 sweet bell pepper, diced
• Splash of sherry (for deglazing)
• Chicken stock (plus extra as needed)
• Fresh thyme, parsley, and/or rosemary
• Bacon

The Method: Prep Five Minutes, the Rest Does Itself

This is a hands-off recipe. The actual active cooking is about five minutes of prep. The rest is patience, low heat, and trust in the process.

1. Soak the Beans

Place your white beans in a bowl and cover with room temperature water. Let them soak overnight until plump. Spread a thin but consistent coat of dry brine evenly over all surfaces of the duck legs. Liberal but not excessive. Place the brined duck legs uncovered in the fridge. The flavours will penetrate right to the bone.

2. The Main Event: Set It, Build It, Walk Away

Preheat your oven to 225°F. Place the duck legs skin-side down in a Dutch oven, snug at the bottom. This low-and-slow approach lets each leg braise in its own rendered fat.

Peel outer layers of the garlic and give the heads a light haircut, a half knob of ginger, and a dried whole chili, exposing them to the middle of the pot. These aromatics infuse the dish with incredible depth of flavour and complement the flavours of the dry brine perfectly as well.

Pro tip: Use an oven thermometer for accuracy — check that it's reading as intended. A few degrees can make a real difference. If you hit a snag and the beans may not be entirely tender, don't stress — the beauty of this recipe is that it's forgiving.

3. Build the Cassoulet Base

Cook the bacon until rendered and crispy. Reserve the strips on a paper towel. Keep the fat in the pan.

Sauté the mirepoix (onion, carrots, celery, bell pepper) at medium heat in the bacon fat until softened. Deglaze with a generous splash of sherry or port. Add the chicken broth and a generous amount of the soaked beans. Reduce everything together, keeping an eye on the liquid — add more stock if it cooks out. Stir gently to combine for maximum flavour. Finish with the fresh herbs, 5 minutes before plating.

4. Crisp the Skin

Carefully remove the duck legs — a claw pair of tongs or a spatula will help with this task. Place them skin-side up on a baking sheet. Broil until the skin is golden, watching closely — it can turn quickly.

Plate each piece of duck on top of the cassoulet, set at an artful angle. Finish with a drizzle of balsamic and a sprinkle of fresh herbs. It looks like you spent all day in the kitchen using restaurant technique — but you didn't. No jar required.

Serve alongside a simple side salad, crusty bread, and a glass of pinot noir for the final, restaurant-level touch.
