One Pot Simplicity
The great thing about this slow-cooker corned beef hash is that it requires only a few ingredients and a few dishes, and it can be reheated throughout the week for dinner. It is also adaptable. Don’t have onions? Add some bell peppers. It’s a great recipe to change up now and then or use the pantry staples you have on hand.
Ingredients
Corned beef – I bought the packaged corned beef brisket that came with a seasoning packet. I did not use the seasoning packet, but chose to use different ingredients. I bought first cut, which refers to the flat cut. It has a little bit less fat, but is more expensive. You can also get point cut, which tends to shred easier.
Corn starch – this is going to help you get thick gravy.
Step-By-Step Instructions


Slice the corned beef and carrots and add them to the slow cooker.


Add the onions, potatoes, ground mustard, salt, and pepper (optional). In a small bowl, mix the beef broth and cornstarch and pour it over the ingredients. Close the lid and cook for 10 hours on the low setting, then serve.
Storage And Reheating Tips
Store any leftover soup in an airtight container and keep it refrigerated.
You can reheat the soup on the stovetop or in the microwave.
Stovetop: Add the soup to a pot and heat over medium-low heat, stirring occasionally. Cook for about 10 minutes or until the soup is hot. If it is too thick, add a little bit of water or broth to the pan.
Microwave – Add the soup to a microwave-safe bowl and cover it with a damp paper towel. Heat on medium power for about 2 minutes, stirring halfway through. Continue to cook until hot.
