Oven-Braised Corned Beef with Brown Sugar Mustard Glaze
Fork-tender and perfectly seasoned, this succulent oven-braised corned beef roast is finished with a brown sugar and mustard glaze that caramelizes as it bakes to create a glossy, gooey, irresistible crust.
Sear the brisket: Heat 1-2 tablespoons oil in a Dutch oven over medium-high heat. When hot, add the corned beef brisket and sear for 3-4 minutes per side, including edges where possible,until lightly browned.
Add braising liquid & aromatics: Remove from heat. Pour in beer (or substitute), then add carrots, onions, and pickling spices around the brisket.
Braise: Cover and transfer to the oven. Bake for 2 to 3½ hours (depends on the brisket) or until the internal temperature reaches 165-175°F.
Make the glaze: While the brisket cooks, melt butter in a small saucepan over medium-low heat. Whisk in brown sugar, mustard, and bourbon (or substitute).Bring to a gentle boil, then reduce heat and simmer for about 5 minutes, until smooth, glossy, and slightly thickened.
Glaze & finish: Line a rimmed baking sheet with parchment or foil. Transfer the brisket to the sheet (fat-side down for best presentation).Brush generously with glaze.
Caramelize: Return to oven and bake uncovered for 30-40 minutes, brushing with additional glaze every 10 minutes, until the internal temperature reaches 195-205°F (90-96°C) and the glaze is sticky and caramelized.
Rest & serve: Remove from oven and let rest for at least 15 minutes before slicing against the grain.
