Slow Cooker Spiced Corned Beef

Two days of brining the beef allows the roast to infuse with flavors of spice and salt. This recipe cooks slowly over time, producing a savory, flavorful Corned Beef. Try this with the typical sides of cabbage and potatoes. Or on an open-faced Reuben. The spice notes in this recipe also work well with Asian Cuisine. Try using it in a Pho Noodle bowl in place of your usual protein!

Slow Cooker Corned Beef

A two day brine infuses a flat cut of brisket with spices and salt. This recipe cuts down on the traditional curing time by several days, but fear not, this technique produces a complex, layered flavor redolent with spices.
