What ingredients do you need for Crockpot Corned Beef with Carrot and Potato Mash?
This recipe requires a mix of corned beef and fresh vegetables, along with seasoning for full flavor. Here’s the complete list:
- 3 lbs corned beef brisket
- 2 cups baby carrots
- 4 medium Yukon Gold potatoes, peeled and chopped
- 1 cup beef broth
- 2 tablespoons butter
- 1/4 cup heavy cream

Corned beef brisket is the star ingredient, offering a savory and tender texture after slow cooking. Yukon Gold potatoes are ideal for a creamy mash due to their buttery flavor and smooth consistency.
How do you make Crockpot Corned Beef with Carrot and Potato Mash step by step?
The method is straightforward, with the crockpot handling most of the work. Follow these steps for a foolproof meal:
Step 1 — Prepare the ingredients
Peel and chop the Yukon Gold potatoes. Trim any excess fat from the corned beef brisket. Gather all other ingredients for easy access.
Step 2 — Add to the crockpot
Place the corned beef brisket into the crockpot, fat side up. Add baby carrots and chopped potatoes around the meat.
Step 3 — Season and pour
Sprinkle garlic powder, salt, and pepper over the ingredients. Pour beef broth into the crockpot, ensuring it covers the bottom. Cover with the lid.
Step 4 — Slow cook
Set the crockpot to low and cook for 8 hours. The long cooking time allows the meat to become incredibly tender while flavors meld together.

Step 5 — Create the mash
Remove the potatoes and carrots once softened. Mash them together in a bowl with butter, heavy cream, salt, and pepper until smooth.
Step 6 — Slice and serve
Remove the corned beef from the crockpot and let it rest for 5 minutes. Slice the meat against the grain and serve with the mash on the side.
Frequently Asked Questions About Crockpot Corned Beef with Carrot and Potato Mash
Can I use russet potatoes instead of Yukon Gold?
Yes, russet potatoes can be substituted, but they may result in a less buttery and smooth mash due to their higher starch content.
Do I need to soak the corned beef brisket before cooking?
Soaking is optional but can reduce the saltiness. Rinse the brisket under cold water if you prefer a milder flavor.
Can I cook this dish on high instead of low?
Cooking on high for 4-5 hours is possible, but low heat for 8 hours yields better tenderness and flavor.
How do I know when the corned beef is done?
The beef is done when it reaches an internal temperature of 145°F and is fork-tender.
Can I freeze leftovers?
Yes, freeze leftover corned beef in an airtight container for up to 3 months. The mash is best eaten fresh but can also be frozen.
Common mistakes to avoid when making this dish
Avoid these mistakes for the best results:
- Not trimming excess fat from the corned beef can result in overly greasy meat.
- Skipping the seasoning step reduces the depth of flavor in both the meat and the mash.
- Cooking on high heat can lead to tough meat; stick to low heat for optimal results.
Meal prep, storage, and reheating tips
Store leftovers in the fridge for up to 4 days in airtight containers. For longer storage, freeze in individual portions for up to 3 months.
To reheat, microwave individual servings or warm them in a covered pan over low heat. Add a splash of broth to prevent the meat and mash from drying out.
Expert tips and pro shortcuts
Here are a few ways to elevate your dish:
- Use a meat thermometer to ensure your corned beef is perfectly cooked.
- Butter and heavy cream can be swapped for Greek yogurt for a lighter mash.
- Layer onions under the corned beef for additional flavor during cooking.
- Sear the corned beef before adding to the crockpot for deeper caramelized flavors.
