Recipe FAQs
This corned beef hash texture is a mix of homemade and canned corned beef hash. The potatoes are nice and soft, like the canned kind from cooking in that amazing broth, and the beef has that same texture of homemade corned beef hash.
If you’re not a fan of the texture of fat, you can trim off some of the fat. I recommend leaving some of it on because that will help give your hash a great flavor. Cutting the corned beef into 1-inch strips, then turning it on the side and trimming off some fat, seems the easiest way to trim the fat.
I like to make this with red potatoes on days I don’t feel like peeling anything, and I want to dump it and go.
I leave the spice packet out for this recipe, but if you want a more traditional corn beef flavor versus corn beef hash, add it.
I think the only thing you need to serve with this is a nice sunny-side-up egg or fried egg. You can choose to serve it with your favorite egg style.
No. The stock provides plenty of coating so nothing sticks during the slow cooking process.
Leftover corned beef hash can be stored in an airtight container and kept in the fridge for up to 4 days. You can also freeze corned beef hash for up to 3 months. Allow it to defrost completely before heating it up over medium heat. I would not use a high heat.
In addition to the basics, you can add a splash of olive oil, a dash of Worcestershire sauce, and minced garlic.
