I’ll be honest: I was never a huge corned beef fan—but my hubby loves it, so a few years ago, I ventured into the corned beef world with a baked version he loved (and shockingly, I enjoyed it too!). Since then, I’ve dabbled here and there, testing out my even simpler recipe for Crock Pot Corned Beef and I’ve never looked back!
This slow cooker version has less than 10 ingredients and cooks all day, making the beef incredibly tender and flavorful (and dinner prep quick too!). For the best texture, add the potatoes and carrots halfway through and the cabbage two hours before it’s done—trust me, tossing them in too early means mushy veggies.
You can either add the cabbage to the slow cooker or try these roasted cabbage steaks for a crisp, flavorful twist. This crock pot corned beef brisket is comfort food at its best, with rich, savory flavors and a hearty meal that practically cooks itself. A classic recipe that is a foolproof way to feed a crowd—no stress, just delicious results!
And don’t toss those leftovers! They’re perfect for corned beef hash the next morning or piled high into sandwiches. Just sayin’…

What is Corned Beef?
The term “corned” comes from the large salt crystals (known as “corns” of salt) that were historically used to cure meat. So yeah, no corn! So corned beef is a salt-cured brisket that’s been treated with a special brine containing large-grained rock salt and various spices. The curing process gives corned beef its distinctive pink color and unique salty flavor, which is slightly tangy and deeply savory. I equate it to ham, because of its salty taste.
It typically comes with a seasoning packet, which includes mustard seeds, coriander seeds, black peppercorns, allspice berries, bay leaves, crushed red pepper flakes, and cloves.
Ingredients
- Onion: Lifts the brisket off the bottom of the pot, infusing flavor too!
- Corned Beef Brisket: Look for one with a spice packet included. The flat cut is leaner, while the point cut has more marbling and tends to be more tender.
- Beef Broth & Better than Bouillon: Provides a rich base for the cooking liquid!
- Worcestershire Sauce: For a tangy, umami flavor.
- Bay Leaves: Bay leaves impart a subtle, earthy flavor to the broth.
- Carrots & Potatoes: I love using Yukon gold potatoes, yellow potatoes (so creamy, and you don’t have to peel them) and carrots. Any waxy potato will work.
- Cabbage: The cabbage pieces become tender and flavorful when cooked in the beef broth, but we won’t add until the last hour.
- Whole Grain Mustard & Parsley: Optional garnishes.

How to Make Crock Pot Corned Beef
Step 1 – Prep the Beef
Lay the onions in the bottom of the crockpot
Rinse the corned beef in cold water to remove excess brine, and pat dry with paper towels. This is an important step so the dish doesn’t become overly salty!
Place the meat on top of the onions in the slow cooker, fat side up. Sprinkle the spice packet on top of the meat.
Make your own seasoning packet: 1 tablespoon mustard seeds, coriander seeds, and black peppercorns. Plus 1 teaspoon whole allspice, 2-3 bay leaves, a few shakes red pepper flakes and 4-6 whole cloves. Lightly crack the mustard seeds, coriander and peppercorns using a mortar and pestle (cracked, not powdered), then add the rest of the spices.
Step 2 – Slow Cook on Low
In a medium-size bowl, combine the beef broth, Better Than Bouillon, and Worcestershire sauce. Pour into the crockpot around the beef. Add the bay leaves, cover the crockpot with the lid and cook on LOW setting for 8-10 hours, some say 8-9 hours, but I’ve found that sometimes it needs to go that extra hour for fall-apart beef.
Step 3 – Add Vegetables
Halfway through the cooking time, add the potatoes and carrots. Cover and continue to cook.
When there are 2 hours of cooking time left, add cabbage to the crockpot, cover and cook for the remaining time.
Step 4 – Serve
Once it’s finished cooking, remove the meat and allow it to rest 5-10 minutes (covered with foil), then slice it against the grain. Serve it topped with whole grain mustard (optional) alongside potatoes, carrots, and cabbage.
Pro Tip: When hosting a gathering, your crockpot becomes the perfect serving vessel for keeping everything warm throughout the meal.
After slicing the corned beef against the grain, return the meat to the slow cooker, arranging it gently among the vegetables and nestling it partially into the flavorful broth. Switch your crockpot to the “warm” setting (not low). This will keep things warm without overcooking them
Expert Tips
- Pick Your Cut: Want juicy, fall-apart beef? Go for the point cut brisket. Prefer clean slices? Flat-cut brisket is your best bet. Both work great!
- Rinse it Before Cooking: A quick rinse removes excess brine so your beef isn’t overly salty—don’t worry, the flavor stays put.
- Layer Like a Pro: Always place the onions on the bottom. They add flavor and keep the beef from sticking.
- Low & Slow Wins: Patience pays off—cooking on low makes the meat melt-in-your-mouth tender.
- Add the Vegetables Halfway Through Cooking: Add potatoes and carrots halfway through, and the cabbage in the last two hours to keep everything perfectly cooked.
- Keep It Juicy: Make sure the beef is mostly submerged in broth. For extra depth, swap some broth with stout beer.
- Slice Against the Grain: Slice against the grain to keep every bite tender and easy to chew. Trust me, it makes all the difference!
Variations & Substitutions
- Swap the Cooking Liquid: Substitute beef broth with stout beer for a deeper, maltier flavor profile.
- Use Different Potatoes: Red potatoes work just as well as Yukon gold if that’s what you have on hand.
- Vegetables: Traditional veggies are carrots, potatoes and cabbage, but use any root vegetables you want!
- Customize the Spices: If your corned beef doesn’t come with a spice packet, use one tablespoon of pickling spice instead, found on the spice aisle (or with canning supplies).
- Make it Low Carb: For a lower-carb version, omit the potatoes and serve with extra cabbage or a side salad.
Storage
Store cooled leftovers in an airtight container in the refrigerator for 3-4 days. Reheat on the stovetop over medium heat until warm or in the microwave or oven for a few minutes until warmed through. It’s even better the next day!
The meat can be frozen in an airtight container for up to 3 months, but I don’t recommend freezing the cooked vegetables as they tend to become mushy.
Leftover corned beef makes excellent Reubens (or sandwiches), corned beef hash, or even a protein-packed addition to salads.
What to Serve with Slow Cooker Corned Beef and Cabbage
Complement your fork tender slow cooker corned beef and cabbage with sides that balance its rich, savory flavor. Here are some great options that I’ve served with this main course:
- Homemade Irish soda bread
- Beer bread
- Guinness brown bread
- Quick two-ingredient biscuits
- Whole-grain mustard or horseradish sauce
- Italian chopped salad
- Classic wedge salad.
- Guinness chocolate cake (for dessert!)
FAQs
The beef should be mostly submerged in liquid to stay moist and create a rich broth, but it doesn’t need to be fully covered. If your brisket is smaller, you may need less liquid—start with 2 cups of broth and add water as needed to adjust.
Cook the corned beef fat-side up so the fat can baste the meat as it cooks, making it extra tender and flavorful. If there’s a lot of fat, trim a little, but leave a good layer for the best results.
For the best results, cook corned beef on low in the slow cooker. The low, slow heat breaks down the meat, making it tender, juicy, and full of flavor.
If your corned beef is tough, it probably just needs more time. Corned beef needs low, slow cooking to break down the connective tissues and turn tender. Be patient—it’ll get there!
Corned beef stays pink or red, even after cooking, because it’s cured with nitrites, which preserve its color. (Source)
Oddly enough, it’s not, but instead legend has it that it was developed by Irish immigrants most likely from the New England boiled dinner concept. Does it really matter, though? I think not!

Equipment
- Crockpot I used a 6 quart
Ingredients
- 1 large onion sliced into ¼-inch slices
- 3 – 5 pound corned beef brisket with spice packet
- 4 cups beef broth
- 1 teaspoon beef Better than Bouillon
- 1 tablespoon Worcestershire sauce
- 2 bay leaves
- 3-4 carrots peeled and cut into 2-inch pieces
- 4-6 Yukon Gold potatoes washed and halved or quartered
- 1 small green cabbage cut into quarters or eighths
- whole grain mustard optional, for serving
- chopped parsley optional garnish
Instructions
- Lay the onions in the bottom of the crockpot.
- Rinse the corned beef in cold water to remove any excess brine, and pat dry with paper towels.
- Place the meat on top of the onions in the slow cooker, fat side up. Add the spice packet on top of the meat.
- In a medium-size bowl, combine the beef broth, better than bouillon, and Worcestershire sauce. Pour into the crockpot around the beef. Add the bay leaves, cover the crockpot and cook on low for 8-10 hours.
- Halfway through the cooking time, add the potatoes and carrots. Cover and continue to cook.
- When there are 2 hours of cooking time left, add cabbage to the crockpot, cover and cook for the remaining time.
- Once it’s finished cooking, remove the meat, and slice it against the grain. Serve it topped with whole grain mustard (optional) alongside potatoes, carrots, and cabbage. Garnish with fresh parsley if desired.
Notes
- Most corned beef comes with a spice packet, if it doesn’t, you can purchase pickling spice and use 1 tablespoon.
- If there is a lot of fat on your meat, feel free to trim it off. Some fat is needed for flavor and tenderness. I did not trim any of the fat as it was reasonable.
- The key to the liquid in this recipe is that the beef is fully submerged, or mostly covered. You may need less broth, depending on the size of your beef and crockpot. You could also start with 2 cups of broth and use water to make up the difference.
- Stout beer can be substituted for some of the broth if you’d like, just an optional variation.
- You can use red potatoes instead of the yukon gold if you prefer.
- You may only need ½ head of cabbage, it really depends on how large the head of cabbage is.
- Waiting to add the vegetables helps to keep them from turning too soft or mushy. If you prefer, you can add the carrots and potatoes at the beginning of the cooking time, but leave the cabbage out until the last two hours. Cabbage is a delicate vegetable that cooks much faster than the rest of the dish. If added too early, it can become overly soft, losing its texture and bright flavor. By waiting until the end of the cooking time, it retains its gentle crunch, shape, and fresh taste.
- Leftover corned beef is perfect for sandwiches, corned beef hash, or even as a topping for salads.
- Store leftovers in an airtight container in the fridge for 3–4 days.
- The meat can be stored in an airtight container in the freezer for up to 3 months, but the cooked vegetables I would not recommend freezing.
