This slow cooker 4-ingredient rustic leek pork belly is the kind of cozy, stick-to-your-ribs meal my Irish mother would pull together on a busy Sunday, then let quietly bubble away all afternoon. It’s all about simple, honest ingredients—pork belly, leeks, a splash of stock, and a touch of salt—working their magic low and slow until the meat is melt-in-your-mouth tender and the leeks turn silky and sweet. With almost no hands-on time and just four basic ingredients, it’s a practical, comforting dish that feels special enough for company but easy enough for any weeknight.
Serve the pork belly thickly sliced over its bed of braised leeks, spooning plenty of the rich brown juices over the top. It’s lovely with creamy mashed potatoes, buttered boiled potatoes, or crusty bread to soak up the sauce. A simple green side salad or steamed green beans brightens the plate and balances the richness. For a more rustic spread, add roasted carrots or parsnips and set everything out family-style so everyone can help themselves.
Slow Cooker Rustic Leek Pork BellyServings: 4
Ingredients
2 to 2 1/2 pounds pork belly, skin removed if attached, left in one slab
4 large leeks, white and light green parts only, cleaned and thickly sliced
1 cup low-sodium chicken stock (or vegetable stock)
2 teaspoons kosher salt (or 1 1/2 teaspoons fine sea salt), divided
Directions
Trim the leeks by cutting off the dark green tops and root ends. Slice the white and light green parts into 1/2-inch rounds. Rinse the slices well in a bowl of cold water, swishing to remove any grit, then drain thoroughly.
Scatter the sliced leeks in an even layer across the bottom of your slow cooker. Sprinkle with 1 teaspoon of the salt. This gives the leeks a head start on softening and seasoning.
Pat the pork belly dry with paper towels. Rub the remaining 1 teaspoon salt all over the meat, including the sides. This simple seasoning helps the pork develop a deeper flavor as it cooks.
Nestle the pork belly, fat-side up, on top of the leeks in the slow cooker. Pour the chicken stock around the pork, trying not to wash off the salt on top. The leeks should be mostly covered in liquid, with the pork sitting above on its bed of leeks.
Cover and cook on LOW for 7 to 8 hours, or on HIGH for 4 to 5 hours, until the pork belly is very tender when pierced with a fork and the leeks are soft and silky. The fat will render and drip down into the leeks, creating rich brown juices.
When the pork is tender, carefully lift the slab of pork belly out of the slow cooker and place it on a cutting board to rest for 10 to 15 minutes. This helps it slice more neatly and keeps the juices in the meat.
While the pork rests, give the leeks and cooking juices in the slow cooker a gentle stir. Taste and adjust the salt if needed. They should be soft, slightly sweet, and coated in the savory brown drippings.
For crispy golden edges like a classic Irish roast, preheat your broiler to high and line a baking sheet with foil. Slice the rested pork belly into thick slices, about 1/2 to 3/4 inch. Lay the slices on the baking sheet, fat-side up, and broil for 3 to 5 minutes, watching closely, until the fat is bubbling and the edges are crisp and golden.
To serve, spoon a generous bed of the braised leeks and brown juices onto warm plates. Top with thick slices of the pork belly, letting the crispy edges sit up on the leeks. Spoon a little extra juice over the top and serve right away.
Variations & Tips
If you have picky eaters, you can slice the pork belly thinner after slow cooking and crisp it in a skillet instead of under the broiler; the smaller pieces often feel more like familiar bacon or roast to kids. For even milder leeks, cut them into smaller pieces so they almost melt into the sauce—this makes them less noticeable for those who say they “don’t like onions.” If you prefer a slightly leaner dish, trim off some of the visible fat from the pork belly before cooking, but leave enough for flavor and tenderness. To stretch the meal for a bigger family, add an extra leek or two and increase the stock to 1 1/2 cups so there’s more of the braised vegetable base to go around. For a deeper, more old-fashioned flavor, you can brown the pork belly in a skillet on the stove before adding it to the slow cooker, but it’s completely optional. Leftovers reheat well: slice the pork and warm it gently with the leeks in a covered skillet over low heat, or tuck slices into crusty rolls with a spoonful of the leeks for a rustic sandwich.
