Ingredients You’ll Need

This isn’t a scavenger hunt—just some pantry basics and a good piece of corned beef.

Main Ingredients:

• 3 to 4 pounds corned beef brisket (with spice packet)
• 1 medium head of green cabbage, cut into wedges
• 1 pound baby potatoes (Yukon golds or red)
• 4 large carrots, peeled and cut into chunks
• 1 large yellow onion, sliced
• 4 cloves garlic, smashed
• 2 cups beef broth
• 1 tablespoon Dijon mustard
• 2 tablespoons olive oil
• Fresh parsley, for garnish

How to Make Corned Beef and Cabbage in the Oven

Trust me—this is a “set it and (mostly) forget it” kind of meal. Just follow these simple steps:

Step 1: Preheat & Prep

Set your oven to 325°F (163°C). While it preheats, grab a large roasting pan or Dutch oven with a lid.

Place the sliced onions and garlic on the bottom of the pan. This creates a flavorful bed for your corned beef.

Step 2: Lay Down the Beef

Place the corned beef brisket (fat side up) on top of the onions and garlic. Sprinkle the spice packet over the meat, then slather on that Dijon mustard—it adds a tangy kick that wakes up the whole dish.

Pour in 2 cups of beef broth, cover tightly with foil or a lid, and pop it in the oven.

Bake for 2.5 hours.

Step 3: Add Veggies

After the beef’s had its beauty nap, take it out and scatter the potatoes, carrots, and cabbage wedges around it. Drizzle them with olive oil, season lightly with salt and pepper, and cover it up again.

Bake for another 1 to 1.5 hours, until the veggies are tender and the beef practically falls apart.

Step 4: Rest & Serve

Take the beef out and let it rest for 10-15 minutes before slicing (always slice against the grain for maximum tenderness).

Plate everything up, spoon some of the pan juices over the top, and sprinkle with fresh parsley for that “I totally have it together” finish.

Tips & Tricks

• Crispy Finish: Want the cabbage to have a little char? Uncover the pan for the last 15 minutes.
• No spice packet? Use 1 tsp each of mustard seeds, peppercorns, coriander, and a bay leaf.
• Lean Brisket Tip: If your cut is lean, add an extra ½ cup of broth to keep it moist.
• Leftovers Hack: Dice leftover meat and cabbage into a hash the next morning with eggs—breakfast win!

And there you have it. A flavorful, heartwarming take on how to cook corned beef and cabbage in the oven that doesn’t involve a giant pot of boiling water or guesswork. Just low heat, love, and a kitchen that smells like comfort.

Common Mistakes to Avoid When Cooking Corned Beef and Cabbage in the Oven

1. Skipping the Rinse

Corned beef comes packed in a salty brine. If you don’t rinse it before cooking, you might end up with a dish that tastes like it fell into the ocean. A quick rinse under cold water helps balance the salt without washing away the flavor.

2. Cooking Too Hot or Too Fast

This isn’t a weeknight stir-fry—it’s a slow-roast situation. Cranking up the oven to “get it done faster” will just give you dry, chewy meat. Stick to 325°F, cover it tightly, and give it time to break down into that dreamy, fork-tender texture.

3. Forgetting to Cover the Pan

Leaving your meat uncovered is basically giving it a one-way ticket to dried-out city. Always cover your roasting dish tightly with foil or a lid to trap in moisture and create that steamy, tenderizing environment.

4. Adding Veggies Too Early

Potatoes, carrots, and cabbage need less time than the meat. If you toss them in at the start, they’ll end up mushy or disintegrated. Wait until the last hour or so of cooking to add them for perfectly tender veggies with some structure.

5. Not Letting the Beef Rest

Cutting into the corned beef straight from the oven is tempting—but patience pays off. Let it rest for 10–15 minutes to keep those juices where they belong: inside the meat.

6. Slicing the Beef the Wrong Way

Always slice against the grain. This shortens the muscle fibers and makes the meat easier to chew. Cut with the grain, and you’re working against yourself (and your jaw).

Avoid these kitchen missteps and you’re well on your way to a corned beef dinner that tastes like it came straight from Grandma’s table—only with way less cleanup. 💚
