Ingredients for 5 lb corned beef and cabbage
Ten hearty ingredients transform a simple pot into a legendary Irish feast—crispy potatoes, tender beef, and cabbage so flavorful you’ll want leftovers.
| Ingredient | Amount | Notes |
|---|---|---|
| Beef Brisket 🥩 | 5 lb | Whole packer cut, trimmed of excess fat |
| Yellow Onions 🧅 | 2 whole | Large, cut into wedges |
| Russet Potatoes 🥔 | 3 lb | Medium, cut into 2-inch chunks |
| Green Cabbage 🥬 | 2 whole | Heads, cut into wedges |
| Carrots 🥕 | 4 whole | Medium, cut into 2-inch pieces |
| Bay Leaves 🌿 | 4 whole | Dried, standard size |
| Mustard Seeds 🌶️ | 2 tbsp | Whole, yellow or brown |
| Black Peppercorns 🌶️ | 1 tbsp | Whole, freshly cracked |
| Salt 🧂 | 4 tbsp | Diamond Crystal kosher |
| Brown Sugar 🍚 | 1 cup | Packed, light brown preferred |
| Apple Cider Vinegar 🍎 | ½ cup | Unfiltered for tang |
| Water 💧 | 6 cups | Filtered preferred |
| Beer 🍺 | 1 bottle | Dark ale or stout (12 oz) |
| Fresh Parsley 🌿 | ¼ cup | Chopped, for garnish |
The 5 lb brisket is non-negotiable here—look for packer cuts at Whole Foods or your local butcher, where the meat is usually pre-trimmed. If buying whole, trim excess fat yourself for cleaner flavor. Costco often has great deals on brisket packs, but check the marbling—fat equals flavor. For the potatoes, Russets are ideal—they hold their shape during parboiling and crisp beautifully. The cabbage should be firm and heavy for its size, with crisp outer leaves. If using green cabbage, remove any wilted outer layers before cutting. Mustard seeds and peppercorns? Penzeys or bulk bins at natural markets have the best quality—avoid pre-ground spices here, as whole seeds deliver deeper flavor when toasted.
No dark beer? Substitute with extra apple cider vinegar and a splash of stout coffee for depth. Short on bay leaves? Double the thyme—it’s a classic swap. The brown sugar can be swapped for turbinado if you prefer a less refined taste, but don’t skip it entirely—it balances the tang. For the potatoes, parboiling is critical—this step ensures they stay crispy instead of mushy. If you’re short on time, pressure cooking cuts the total time by half while keeping the beef tender. And if your cabbage is particularly large, core it first to speed up cooking. The beer adds richness, but if you’re avoiding alcohol, use non-alcoholic stout—it mimics the malty notes perfectly.
This dish tastes even better the next day—plan ahead and make extra. The broth freezes beautifully for up to 3 months, so portion it into containers for quick soups later. Store the beef and veggies separately in the fridge for 4-5 days, or freeze the entire pot for up to 6 months (just thaw overnight in the fridge). For crispy potatoes, reheat them separately in a skillet with a splash of broth to restore their crunch. Garnish with fresh parsley right before serving—it brightens the dish and looks stunning. Leftovers? Double the recipe—this is the kind of meal people will beg you to make again.

Step-by-step instructions for slow-braised corned beef with crispy potatoes
Here’s how to transform a tough brisket into melt-in-your-mouth perfection with crispy potatoes and tender cabbage.
Prep and Season the Brisket for Maximum Flavor
Begin by trimming the 5 lb Beef Brisket of any excess fat, leaving about ¼-inch layer to protect the meat during cooking. Pat the brisket dry with paper towels—this step is crucial for developing that crispy exterior we’re after. In a small bowl, combine 4 tbsp Salt, 1 tbsp Black Peppercorns, 2 tbsp Mustard Seeds, and 1 cup Brown Sugar. Rub this mixture generously over the brisket, pressing it into all sides and the cavity.
Place the seasoned brisket in a large Dutch oven or heavy pot, fat-side up. Add the 2 whole Yellow Onions (cut into wedges), 4 whole Carrots (cut into 2-inch pieces), and 4 whole Bay Leaves around the brisket. Pour in the 6 cups Water and 0.5 cup Apple Cider Vinegar, then add the 1 bottle Beer (dark ale works best). The liquid should cover about two-thirds of the brisket—if it doesn’t, add a splash more water.
Simmer Low and Slow for Tender Perfection
Cover the Dutch oven and bring to a gentle boil over medium-high heat. Once boiling, immediately reduce heat to low and maintain a steady simmer. This is where patience pays off—simmer uncovered for 3 hours, skimming off any foam that rises to the surface. After 3 hours, check the brisket’s tenderness by inserting a fork into the thickest part. If it pierces easily, it’s ready; if not, continue simmering for another 30-60 minutes.
Here’s the thing—don’t rush this step. The slow cook ensures the brisket becomes fork-tender without drying out. The beer and vinegar create a rich, tangy braising liquid that infuses every bite. If the liquid reduces too much, add a splash of water to keep the brisket submerged.
Add Potatoes and Cabbage for Crispy Texture
After the brisket is tender, carefully remove it from the pot and set it aside on a cutting board. Add the 3 lb Russet Potatoes (cut into 2-inch chunks) and 2 whole Green Cabbage (cut into wedges) to the braising liquid. Return the heat to medium-low and simmer uncovered for 45-60 minutes, stirring occasionally. You want the potatoes to develop a golden, crispy exterior while remaining tender inside—they should feel firm to the touch but still yield slightly when pressed.
Real talk: the potatoes are the make-or-break element here. If they’re not crispy, your dish falls flat. To ensure crispiness, don’t overcrowd the pot—work in batches if needed. The cabbage should soften but still hold its shape, with just a hint of bite. Taste the liquid and adjust seasoning with additional salt if needed.
Rest and Slice for Juicy, Flavorful Results
Once the potatoes are crispy and the cabbage tender, remove the brisket from the cutting board and transfer it back to the pot. Increase the heat to medium and simmer for another 15-20 minutes to allow the brisket to absorb the remaining braising liquid. This final step ensures every slice is moist and packed with flavor.
Remove the brisket from the pot and let it rest on a cutting board for 10-15 minutes before slicing. This resting period allows the juices to redistribute, preventing dry slices. Slice the brisket against the grain into ¼-inch thick pieces. Serve the brisket, potatoes, and cabbage together, garnished with 0.25 cup Fresh Parsley for a pop of color and freshness.
Serve with Crispy Potatoes and Tangy Braising Liquid
Spoon the braising liquid over the sliced brisket and serve immediately. The potatoes should be golden and crispy on the outside, with a fluffy interior. Each bite of brisket should be tender, juicy, and infused with the rich flavors of the beer, vinegar, and spices. The cabbage should be soft but still hold its shape, absorbing the tangy, savory liquid.
Don’t skip the braising liquid—it’s the soul of this dish. Serve it ladled over the brisket and potatoes, or use it to moisten mashed potatoes or crusty bread on the side. This recipe delivers on the promise of crispy potatoes and melt-in-your-mouth brisket, all in one hearty, satisfying meal.
Pro Tips For Making 5 Lb Corned Beef And Cabbage
- Trim the Fat First: Slice off that thick layer of fat from the brisket before cooking—yes, it’s tempting to leave it, but it’ll render into grease and make your pot look like a science experiment. A ¼-inch trim keeps the meat juicy and the broth clear, so you’re not fighting a grease fire later.
- Parboil the Potatoes: Toss the Russets in boiling water for 5 minutes first, then drain. This softens them just enough so they don’t turn to mush later, but still hold their shape when simmering with the beef. I learned this the hard way—overcooked potatoes ruin the whole dish.
- Don’t Crowd the Cabbage: Cut the green cabbage into wedges (not shreds) and pack them loosely around the brisket. Shredded cabbage turns to soup, and tight packing steams instead of caramelizing. Leave space—your future self will thank you when the edges get crispy.
- Use the Corned Beef Juice: After removing the brisket, don’t pour out that pink-tinged liquid—it’s flavor gold. Stir it into the potatoes and carrots at the end for a richer taste. I skip this sometimes, and the dish feels flat without it. (Yes, even if you’re impatient like me.)
Essential equipment for this dish
Dutch Oven Essentials
A heavy-bottomed Dutch oven is your secret weapon for even heat distribution and crispy potatoes. I swear by a Le Creuset 6-quart—it holds heat beautifully and lasts forever. For budget-friendly options, Lodge’s 5.5-quart cast iron works just as well, though it requires more attention to prevent burning. Make sure your pot has a tight-fitting lid to trap steam during the initial simmer. 🔥
Meat Thermometer
Never guess the doneness of your brisket—use a digital instant-read thermometer like the ThermoWorks Smoke to monitor internal temperature. Aim for 205°F in the thickest part, which ensures fork-tender perfection. I keep mine within 5°F of the target to avoid overcooking. For traditionalists, a candy thermometer works too, but digital is more precise.
Potato Parboiling Tools
To achieve those crispy potatoes, parboil them first in a separate pot before adding them to the braising liquid. Use a large stainless steel pot (like All-Clad) to prevent sticking—it heats evenly and won’t react with acidic ingredients. A fine-mesh strainer (like OXO Good Grips) helps drain them quickly after parboiling, keeping them from steaming back into mush.
Spice Grinder
Whole spices like mustard seeds and peppercorns deliver deeper flavor when toasted and freshly cracked. My go-to is a KitchenAid Spice Grinder—it’s durable and gives you control over coarseness. Avoid pre-ground spices here; they lose potency quickly. Toast your spices in the Dutch oven for 1-2 minutes before adding liquid to wake up their flavors. 🌶️
Tongs for Handling
Long-handled tongs (like Mercer Culinary Genius) are a game-changer for flipping potatoes and cabbage without burning your hands. They’re also great for lifting the brisket in and out of the pot without tearing the meat. I keep mine within easy reach while cooking—no more fumbling for utensils mid-recipe.Storage Containers
Leftovers taste even better the next day, so invest in airtight glass containers (like Pyrex) for storage. They’re microwave-safe and won’t absorb odors. For the broth, freeze it in quart-sized freezer bags—squeeze out excess air to prevent freezer burn. Label everything with dates to keep track of freshness. Trust me, you’ll thank yourself when you’re reheating that rich, flavorful broth later. ❄️

Frequently asked questions
Can I substitute regular brisket for corned beef?
Yes, but it won’t be the same! This recipe uses 5 lb brisket seasoned with corned beef spices (mustard seeds, peppercorns, etc.). For authentic corned beef flavor, buy a 5 lb corned beef brisket from the deli section—it’s pre-seasoned with the traditional salt cure. If using plain brisket, follow the seasoning steps exactly for the best results.
How do I make this in a slow cooker?
Transfer the seasoned brisket, onions, carrots, and bay leaves to your slow cooker. Add all liquids (water, vinegar, beer) and cook on low for 8 hours or high for 5 hours. Then add potatoes and cabbage, cooking an additional 2-3 hours until potatoes are crispy. The slow cooker makes the brisket extra tender—just check for doneness with a fork!
Why are my potatoes mushy instead of crispy?
This happens when potatoes steam instead of crisping. First, always parboil potatoes for 5 minutes before adding them to the pot. Second, don’t overcrowd the pot—work in batches if needed. Finally, keep the heat at medium-low and stir occasionally to prevent steaming. For extra crispiness, add potatoes in two batches, 30 minutes apart.
Can I use green cabbage or must I use red?
Green cabbage is traditional and works perfectly! It has a milder flavor that lets the spices shine. Red cabbage adds sweetness and color, but it softens more quickly. For best results, use green cabbage cut into wedges—this keeps it slightly crisp while absorbing the rich broth. If using red, reduce cooking time by 10-15 minutes to prevent mushiness.
How long will leftovers keep?
The beef and vegetables stay fresh in the fridge for 4-5 days when stored in airtight containers. The broth freezes beautifully for up to 3 months—portion it into freezer bags for quick soups later. For reheating, warm the beef and veggies separately in a skillet with a splash of broth to restore crispiness. The broth can be reheated on its own for mashed potatoes or gravy.
