My uncle swears by this method for St. Patrick's Day. Just 5 ingredients. Wrap them up individually and let them steam to perfection for the easiest holiday dinner ever.
Every March, right as the snow is half-melted and the fields are still too soggy to walk, my uncle hauls out his old slow cooker and makes these little corned beef packets for St. Patrick’s Day. He swears by this method because it keeps everything tidy, tender, and full of flavor without babysitting a pot on the stove. Each serving is wrapped up in its own foil bundle with just five simple ingredients, then tucked into the slow cooker to steam away. It’s very much a Midwestern, farmhouse take on the holiday—practical, comforting, and easy enough to pull off even on a busy weekday, but special enough to feel like a tradition worth keeping.
Serve each foil packet right out of the slow cooker, opening it at the table so the steam and aroma stay trapped until the last second. Spoon any juices over the meat and vegetables, and add a wedge of Irish soda bread or a slice of buttered rye on the side to soak up the broth. A simple green salad or a dish of applesauce fits nicely with the rich corned beef. If you like, pass a little extra grainy mustard at the table, and finish the meal with something homey like bread pudding or a pan of brownies to keep that cozy, small-town supper feeling.
Slow Cooker 5-Ingredient Corned Beef Packets
Servings: 6
Ingredients
3 pounds corned beef brisket with seasoning packet, cut into 6 equal pieces 1 1/2 pounds small red potatoes, scrubbed and halved 4 large carrots, peeled and cut into 2-inch chunks 1 small head green cabbage, cored and cut into 6 wedges (plus extra leaves for garnish, optional) 1 cup low-sodium beef broth or water
Directions
Lay out 6 large sheets of heavy-duty aluminum foil, each about 12x18 inches. If using regular foil, double-layer each sheet so the packets don’t tear. Lightly crimp the edges up a bit to form shallow trays so juices don’t run off while you’re filling them.
Cut the corned beef brisket into 6 equal portions, keeping as much of the seasoning and fat with each piece as you can. If your brisket came with a seasoning packet, sprinkle it evenly over all the meat pieces.
Divide the potatoes and carrots evenly among the foil sheets, piling them in the center of each. Place one piece of corned beef on top of the vegetables in each packet.
Tuck a wedge of cabbage beside or on top of the corned beef in each packet. If you like a prettier presentation, line the bottom of each foil piece with a large outer cabbage leaf first, then build the packet on top of that leaf so it shows nicely when you open the packets later.
Drizzle about 2 to 3 tablespoons of the beef broth (or water) over the contents of each foil packet. This small amount of liquid will create steam inside the packets and in the bottom of the slow cooker without watering down the flavor.
Bring the long sides of each foil sheet up over the corned beef and vegetables, then fold them together tightly several times to seal. Fold in the short ends to make a snug packet, making sure there are no big gaps where steam could escape. The tighter the seal, the better the steaming.
Pour any remaining broth (if you have a bit left) into the bottom of a large slow cooker. Arrange the foil packets upright or slightly overlapping inside the slow cooker, seam side up. It’s fine if they’re stacked a bit, as long as the lid can close securely.
Cover the slow cooker with the lid. Cook on LOW for 8 to 9 hours, or on HIGH for about 4 to 5 hours, until the corned beef is very tender and the vegetables are soft when pierced with a fork.
Once cooked, carefully lift the packets out of the slow cooker with tongs. Open each one cautiously—steam will rush out. Transfer the corned beef, potatoes, carrots, and cabbage to plates, or serve each person their own open packet, spooning the flavorful juices over the top.
Garnish with extra fresh cabbage leaves if you like that pretty touch you see in photos, and let everyone season to taste with a little black pepper. Serve hot, straight from the packets, for an easy St. Patrick’s Day dinner with almost no cleanup.
Variations & Tips
If you prefer more vegetables, you can tuck in sliced onions or parsnips without changing the method; just keep the total amount similar so the packets still close easily. For a milder flavor, rinse the corned beef under cold water and pat it dry before cutting and seasoning—this washes away some of the brine. If you don’t care for the spice packet, skip it and add a small pinch of dried thyme or a bay leaf piece to each packet instead. To make ahead, assemble the foil packets up to a day in advance, refrigerate them on a tray, then load them into the slow cooker the next morning. For smaller households, make the full batch and refrigerate or freeze cooked packets; they reheat nicely in a 300°F oven until warmed through. If you’d like a crisper edge on the corned beef, open the cooked packets and slide the meat under the broiler for a few minutes before serving, leaving the vegetables in the foil to stay moist.
