how to make Tender Slow Cooker Corned Beef Recipe with Mustard Glaze
Start by laying sliced onion, carrots, and potatoes in the slow cooker. Rinse and pat dry the corned beef, then place it fat side up on the vegetables. Add the brisket spice packet, garlic, bay leaves, and peppercorns. Pour beef broth around the meat and cook low until fork-tender. Make a simple mustard glaze near the end, brush it on, and broil briefly to caramelize. Let the meat rest, slice against the grain, and serve with the vegetables and juices.
