Instructions

Oven Roasted Corned Beef And Cabbage Recipe

Preheat and Prep

Preheat your oven to 325°F. Take the corned beef brisket out of its packaging and rinse it under cold water to remove any excess salt. Pat it dry with paper towels. Place the brisket fat side up in the roasting pan and sprinkle the included spice packet over the top.

Add the Veggies

Arrange the cabbage wedges, carrots, and potatoes around the brisket in the pan. Pour the water into the bottom of the pan to keep everything moist during cooking. Drizzle the melted butter over the vegetables for added flavor.

Cover and Roast

Cover the pan tightly with aluminum foil and place it in the preheated oven. Roast for about 3 hours, or until the beef is fork-tender. Tip: Check the water level halfway through and add more if necessary to prevent drying out.

Uncover and Brown

Remove the foil and increase the oven temperature to 425°F. Roast for an additional 15-20 minutes to brown the beef and vegetables slightly. This step adds a nice texture and color to the dish.

Rest and Serve

Let the corned beef rest for about 10 minutes before slicing against the grain. Serve the sliced beef with the roasted vegetables and a bit of the cooking liquid for extra moisture.

Tips and Tricks

For an even more flavorful dish, consider adding a bottle of stout beer to the roasting pan instead of water. The beer will reduce and create a rich sauce. If you’re short on time, you can cut the brisket into smaller pieces before roasting to reduce cooking time. Always let the meat rest before slicing to ensure it stays juicy. For a crispier cabbage, place it under the broiler for the last few minutes of cooking. Experiment with different vegetables like parsnips or turnips for variety.

Recipe Variations

  • Try using a slow cooker for this recipe if you prefer a set-it-and-forget-it method. Just layer the ingredients and cook on low for 8 hours.
  • Add a tablespoon of brown sugar to the spice rub for a slightly sweet and caramelized exterior on the beef.
  • For a spicy kick, include a teaspoon of crushed red pepper flakes with the spices.
  • Swap out the cabbage for Brussels sprouts for a different but equally delicious vegetable option.

Frequently Asked Questions

Can I make this recipe ahead of time?

Absolutely! This dish actually tastes better the next day as the flavors have more time to meld. Just store it in the refrigerator and reheat in the oven or microwave before serving.

What if I can’t find a corned beef brisket with a spice packet?

No worries! You can make your own spice blend with mustard seeds, coriander, bay leaves, peppercorns, and allspice. Just mix them together and rub onto the brisket before roasting.

How do I know when the corned beef is done?

The beef is ready when it’s fork-tender. This means a fork should easily slide into the meat with little resistance. If it’s still tough, cover and continue roasting, checking every 30 minutes.

Summary

This oven-roasted corned beef and cabbage recipe is a foolproof way to enjoy a classic dish with minimal effort and maximum flavor. Perfect for any occasion, it’s sure to become a family favorite.
