Ingredients List

To make the perfect slow cooker corned beef, you’ll need the following ingredients:

Main Ingredients:

• 3-4 lb corned beef brisket (with spice packet) – The star of the dish, cured for deep flavor.
• 4 cups beef broth – Enhances richness and keeps the meat juicy.
• 1 cup water or Guinness beer – Beer adds depth, but water works just as well.
• 2 tbsp apple cider vinegar – Helps tenderize the meat while adding tang.
• 1 tbsp brown sugar – Balances the salty, briny taste of the beef.
• 1 tbsp Dijon mustard – Adds a slight tangy kick.
• 1 lb baby potatoes (halved) – Absorbs flavor and makes the dish heartier.
• 4 large carrots (cut into chunks) – Adds a natural sweetness.
• 1 onion (quartered) – Gives the broth a deep, aromatic base.
• 3 cloves garlic (smashed) – Infuses the dish with warmth.
• ½ head cabbage (cut into wedges) – A classic pairing with corned beef.

Optional Additions:

• 1 bay leaf – Adds an earthy undertone.
• ½ tsp black peppercorns – For extra spice and depth.
• 1 tbsp Worcestershire sauce – Enhances umami flavors.

Substitutions:

• Swap beef broth for chicken broth for a lighter taste.
• Use honey instead of brown sugar for a natural sweetness.
• Replace Dijon mustard with horseradish for an extra punch.

Timing

One of the best things about this slow cooker corned beef recipe is how effortless it is!

• Prep Time: 10 minutes
• Cook Time (Low Setting): 8-10 hours
• Cook Time (High Setting): 4-5 hours
• Total Time: 8-10 hours (low) or 4-5 hours (high)

For the most tender and juicy results, I highly recommend the low-and-slow method!

Step-by-Step Instructions

Step 1: Prep the Slow Cooker

Place the onion, garlic, carrots, and potatoes in the bottom of the slow cooker to create a flavorful base for the beef to rest on.

Step 2: Add the Corned Beef & Liquids

Place the corned beef brisket (fat side up) on top of the veggies. Sprinkle the spice packet over the meat. Pour in the beef broth, water (or beer), apple cider vinegar, and Worcestershire sauce.

Step 3: Cook Low & Slow

Cover and cook on LOW for 8-10 hours or HIGH for 4-5 hours. The low setting gives the best results, allowing the beef to become incredibly tender.

Step 4: Add the Cabbage

With 1 hour left in cooking time, add the cabbage wedges on top. This prevents them from becoming too mushy.

Step 5: Serve & Enjoy!

Once the beef is fork-tender, remove it from the slow cooker and let it rest for 10 minutes before slicing. Serve with the veggies and drizzle some of the cooking juices over the top for extra flavor.

Healthier Alternatives for the Recipe

Common Mistakes to Avoid

Avoid these pitfalls to make sure your corned beef turns out perfect every time:

• Not rinsing the meat – Some corned beef brands are very salty. A quick rinse helps balance the flavors.
• Cooking on high heat the entire time – Low and slow is best for a tender texture.
• Overcooking the cabbage – Add it in the last hour to keep it from getting mushy.
• Skipping the resting time – Letting the meat sit before slicing ensures juicier results.

Storing Tips for the Recipe

• Refrigerate: Store leftovers in an airtight container for up to 4 days.
• Freeze: Wrap tightly and freeze for up to 3 months.
• Reheat: Warm in a skillet with a bit of broth or in the microwave.
