Ingredients for Corned Beef and Cabbage Recipe in Oven
About 3 to 4 pounds corned beef brisket, including the seasoning packet
2 to 3 tablespoons Dijon or wholegrain mustard
1 and 1 half to 2 tablespoons brown sugar
2 to 3 cups dark beer, beef broth, or water, just enough to reach halfway up the brisket
4 medium red potatoes, quartered
3 large carrots, peeled and cut into thirds
1 medium onion, cut into chunky pieces
1 small head of cabbage, cut into 6 to 8 wedges
How to Make This Corned Beef and Cabbage Recipe in the Oven
- Warm the oven and prepare the brisket.
Heat the oven to 325°F. Rinse the brisket briefly under cool water to remove excess brine, then pat it fully dry.
Place it in a large Dutch oven or deep roasting pan with the fatty side facing up so it stays moist during cooking. - Season the brisket for a savory crust.
Spread a thin, even layer of mustard on top of the brisket.
Sprinkle the included spice packet over the mustard, then add a light layer of brown sugar.
As the meat roasts, the sugar melts into a gentle glaze and the mustard helps the seasonings hold in plac - Add the liquid and start the slow roast.
Pour beer, beef broth, or water into the pan until the liquid reaches about halfway up the sides of the brisket.
Cover tightly with foil or place the lid on the pot.
Cook for 2 hours without lifting the cover so the brisket begins to soften. - Add the vegetables and continue cooking.
After 2 hours, carefully uncover the pan.
Nestle the potatoes, carrots, onion, and cabbage around the brisket, letting them sit partly in the cooking liquid.
No need to parboil the potatoes because the remaining slow cook time is long enough to soften them gently.
Larger pieces stay firmer, smaller pieces soften more, so choose the size you prefer.
Re-cover the pan and return it to the oven for another 90 minutes to 2 hours, or until the brisket is very tender and reaches the upper 170s to low 180s internally. - Optional browning.
If you’d like a deeper color on top, move the brisket to a sheet pan and broil it for about 3 minutes, watching closely so it doesn’t overbrown. - Rest and slice.
Transfer the brisket to a cutting board and let it rest for about 10 minutes. Slice gently against the grain so each piece stays tender. - Serve warm.
Arrange the cabbage, carrots, potatoes, and onion on a platter. Add the sliced brisket and spoon a little of the cooking liquid over everything to keep it moist and flavorful.
