Ingredients for baked corned beef brisket and cabbage
Six hearty ingredients transform into a St. Patrick’s Day centerpiece with crispy potatoes and tender cabbage.
| Ingredient | Amount | Notes |
|---|---|---|
| Corned Beef Brisket 🥩 | 4 lb | Packaged corned beef brisket preferred |
| Green Cabbage 🥬 | 2 lb | Heads cut into wedges |
| Russet Potatoes 🥔 | 2 lb | Cut into 1-inch chunks |
| Yellow Onion 🧅 | 1 whole | Thickly sliced |
| Garlic Cloves 🧄 | 6 cloves | Minced for depth |
| Carrots 🥕 | 4 whole | Cut into thick coins |
| Beef Broth 💧 | 2 cups | Low-sodium preferred |
| Apple Cider Vinegar 🍎 | ¼ cup | For tangy depth |
| Bay Leaves 🌿 | 2 whole | Fresh if possible |
| Black Peppercorns 🌶️ | 1 tbsp | Crushed lightly |
| Salt 🧂 | 1 ½ tbsp | Kosher or sea salt |
| Olive Oil 🫒 | ¼ cup | For crispy potatoes |
| Fresh Parsley 🌿 | ¼ cup | Chopped for garnish |
The brisket is the star—packaged corned beef brisket from Costco or your local butcher delivers consistent quality. Look for good marbling and a 4-pound cut for perfect portions. If you’re brining it overnight, use 2 cups water, 2 tbsp salt, 2 tbsp sugar, and 2 tbsp apple cider vinegar per pound of meat. The cabbage should be firm and heavy—avoid wilted heads. For the potatoes, Russets hold up best to crisping, but Yukon Golds add creaminess if you prefer. The yellow onion adds sweetness as it cooks, so don’t skip it.
No corned beef brisket? Substitute beef short ribs (add 1 hour to cooking time) or beef chuck roast (increase brine time). Running short on cabbage? Green or red cabbage works equally well—just adjust cooking time slightly. The apple cider vinegar can be swapped for red wine vinegar in a pinch, but it won’t have the same depth. For the potatoes, toss them in olive oil and salt before roasting to ensure crispiness. If you’re short on garlic, garlic powder at half the amount works, though fresh is ideal. The bay leaves can be omitted if you dislike their flavor, but they add subtle earthiness.
The brined brisket keeps 3 days in the fridge before baking, while the raw potatoes and cabbage should be prepped the same day for best texture. Once baked, the corned beef reheats beautifully—simmer in its juices for 10 minutes. The cabbage and potatoes are best served fresh but can be reheated gently for 2 days. For make-ahead convenience, portion the potatoes separately and reheat in a 400°F oven for 15 minutes to restore crispiness. Store leftovers in airtight containers for up to 4 days, or freeze the brisket for 3 months—it tastes even richer after resting.
Why You'll Love This Recipe
- One-Pan Magic: I swear by this recipe because it’s the rare dish where you only need a sheet pan and 30 minutes of hands-off time. No chopping boards overflowing, no pots to scrub—just slice the cabbage, toss it with the onions and potatoes, and let the oven do the heavy lifting.
- Flavor Bomb: That crispy, caramelized edge on the brisket? It’s all thanks to the garlic and corned beef juices mingling with the cabbage’s slight bite. Honestly, the first bite makes me forget it’s just a weeknight dinner—it tastes like a celebration.
- Leftovers That Win: Between us, this recipe begs for seconds, which means you’ll always have something hearty for lunch. I’ve reheated the brisket in a skillet with a splash of broth, and it’s just as rich the next day—plus, the potatoes soak up all the flavor like sponges.
- Budget-Friendly Feast: You’re getting a whole meal for less than $15 at the grocery store. The brisket’s salty-sweet punch stretches across multiple servings, and the cabbage and potatoes fill you up without breaking the bank. It’s my go-to when I need to feed a crowd without stressing.
Step-by-step instructions for baked corned beef brisket with crispy potatoes
This method delivers melt-in-your-mouth brisket with perfectly crispy potatoes and tender cabbage—no slow cooker needed.
Prep the Brisket and Season the Potatoes
Remove the 4 lb corned beef brisket from its packaging and place it in a large roasting pan. Pat it dry thoroughly with paper towels—this ensures a crispy exterior. In a small bowl, mix together 1.5 tbsp salt, 1 tbsp crushed black peppercorns, and the 6 minced garlic cloves. Rub this mixture all over the brisket, pressing it into the surface.
Meanwhile, toss the 2 lb russet potatoes (cut into 1-inch chunks) with 0.25 cup olive oil and 1 tbsp salt in a large bowl. Spread them evenly on a parchment-lined baking sheet. Roast these at 425°F for 20 minutes until they begin to brown—this jump-start gives you that coveted crispy texture later.
Build the Vegetable Layer and Arrange the Brisket
After removing the potatoes from the oven, reduce heat to 325°F. In the same roasting pan, layer the 2 lb green cabbage (wedges), 1 whole yellow onion (thickly sliced), 4 whole carrots (cut into thick coins), and the 2 whole bay leaves around the brisket. Pour the 2 cups beef broth and 0.25 cup apple cider vinegar over everything, ensuring the brisket is mostly submerged.
Here's the thing—this liquid mixture creates steam that tenderizes the brisket while keeping the vegetables moist. The vinegar adds a subtle tang that balances the richness of the meat. Cover the pan tightly with aluminum foil and place it in the oven.
Bake Until Fork-Tender
Bake uncovered for 3 hours, maintaining the 325°F temperature. After 2 hours, check the brisket—it should be tender enough to pierce easily with a fork. If not, continue baking for another 30 minutes. The potatoes should now be golden and crispy on the edges.
Real talk: Your oven might run hot, so start checking at the 2-hour 45-minute mark. The brisket is done when it reaches 205°F internally and pulls apart with minimal resistance. If the liquid reduces too much before the brisket is tender, add ¼ cup water and cover again.
Rest and Serve with Crispy Topping
Remove the brisket from the oven and transfer it to a cutting board. Tent it loosely with foil and let it rest for 15 minutes. This resting period allows the juices to redistribute, ensuring every slice stays moist. Meanwhile, return the potatoes to the oven for 5-10 minutes to crisp up further.
Slice the brisket against the grain into ½-inch thick pieces and arrange it on a platter. Spoon the pan juices over the top, garnish with 0.25 cup chopped fresh parsley, and serve immediately with the crispy potatoes and tender vegetables. The potatoes should be golden and crispy on the outside, fluffy on the inside, and the cabbage should be just tender—not mushy.
Pro Tips For Making Baked Corned Beef Brisket And Cabbage
- Sear the Brisket First: I learned this the hard way—skipping the sear means a bland, gray crust instead of that rich, caramelized flavor. Pat the brisket dry, then hit it with a hot pan (no oil needed—just the fat) for 3-4 minutes per side until deep brown. The Maillard reaction here is non-negotiable for that restaurant-quality taste.
- Cut Potatoes in Uniform Chunks: Uneven potatoes mean some get mushy while others stay rock-hard. Aim for 1.5-inch cubes—big enough to hold shape but small enough to cook through in the same time as the brisket. No one wants a side of potato soup instead of crispy edges.
- Don’t Overcrowd the Cabbage: Tightly packed cabbage steams instead of roasting, turning limp and sad. Arrange the wedges cut-side down in a single layer, then roast uncovered for the first 20 minutes. Let that heat work its magic—crowding just traps moisture and kills the crisp-tender texture.
- Check Internal Temp at 2 Hours: Brisket’s tricky—it can look "done" on the outside but still be tough in the middle. Use a meat thermometer to pull it at 195°F (yes, even if it feels undercooked). The connective tissue breaks down at that temp, making it fork-tender. Rest it 15 minutes before slicing—your patience will pay off.
Make-ahead tips for this dish
Brining Ahead
The brisket does most of its flavor development during the overnight brine. I recommend prepping it 24 hours before baking—this ensures maximum moisture and seasoning penetration. Use a large resealable plastic bag or glass baking dish with 2 cups water, 2 tbsp salt, 2 tbsp sugar, and 2 tbsp apple cider vinegar per pound of meat. Seal tightly and refrigerate. The brined brisket keeps 3 days in the fridge, so you can prep it days ahead without stress. 🥩
Pre-Cut Vegetables
Save time by prepping the cabbage, onions, and carrots the day before and storing them in airtight containers in the fridge. Cut the cabbage into wedges, slice the onion, and chop the carrots into thick coins. This step alone cuts your active cooking time by 30 minutes on the big day. Just
Potato Pre-Roast
Here’s my pro tip: Roast the potatoes first and store them in an airtight container at room temperature for up to 12 hours before baking. Toss them with olive oil and salt, then roast at 425°F for 20 minutes until they start browning. Let them cool completely before storing. When you’re ready to bake the brisket, simply return them to the oven for 5-10 minutes to restore crispiness. This two-stage method guarantees perfect texture every time. 🥔
Make-Ahead Juice Reduction
After baking, let the brisket rest while you reduce the pan juices. Simmer them uncovered on the stovetop for 10-15 minutes until thickened. Store these reduced juices in a small airtight container in the fridge for up to 5 days—they’re perfect for reheating slices of corned beef later. The concentrated flavor makes leftovers taste even richer. 💧
Freezer-Friendly Brisket
If you’re prepping for a crowd, bake the brisket 2 days ahead and freeze it. Wrap it tightly in plastic wrap, then in foil, and store for up to 3 months. Thaw overnight in the fridge before reheating. To serve, simmer the brisket in its juices for 10 minutes on the stovetop or in a 350°F oven for 20 minutes. The texture stays tender, and the flavor deepens over time. ❄️
Leftovers Strategy
Store leftovers in individual portions for easy reheating. The brisket reheats best in a saucepan with a splash of beef broth over medium-low heat for 10 minutes. The cabbage and potatoes reheat well in the microwave for 2-3 minutes on 50% power, covered with a damp paper towel. For crispy potatoes, pop them in a 400°F oven for 10 minutes before serving. 💡

Frequently asked questions
How long should I brine the corned beef brisket?
For best results, brine the 4 lb brisket for 12-24 hours in a mixture of 2 cups water, 2 tbsp salt, 2 tbsp sugar, and 2 tbsp apple cider vinegar per pound of meat. This ensures maximum flavor penetration and juiciness.
Can I use a slow cooker instead of an oven?
For a slow cooker version, place the brined brisket in the pot, add all vegetables and liquids, then cook on low for 8-10 hours or high for 5-6 hours. The texture will be slightly different but still delicious. Just avoid adding extra liquid—it should mostly cover the brisket.
Why does my cabbage turn mushy?
Mushy cabbage usually happens from overcooking. The cabbage should be tender but still hold its shape—about 2-2.5 hours in the oven with the brisket. If using pre-cut coleslaw mix, reduce cooking time by 15-20 minutes. Always check at the 2-hour mark to avoid overcooking.
What's the best way to reheat leftovers?
Reheat brisket slices in a saucepan with a splash of beef broth over medium-low heat for 10 minutes. For potatoes, pop them in a 400°F oven for 10 minutes to restore crispiness. Cabbage reheats best in the microwave for 2-3 minutes on 50% power with a damp paper towel covering it.
Can I make this recipe gluten-free?
Yes! Check your corned beef brisket packaging for gluten-free certification. If using a homemade brine, ensure all spices and broth are gluten-free. The cabbage and potatoes are naturally gluten-free, so the rest of the recipe remains safe for gluten-free diets. Always verify ingredient labels first.
