Canned Corned Beef Hash

When I was growing up canned corned beef hash was very much a thing. You would get excited as the can of corned beef (usually Princes corned beef) was opened and then eat in silence because corned beef hash was one of those amazing true comfort foods.

It was passed onto me by my grandparents who had raised five daughters during the UK rationing era.

They were incredibly talented at stretching meals to feed many mouths and were experts at getting the best use out of every rationed food.

Canned corned beef was one of the geniuses of the rationing era thanks to it being on the list, lasting in the pantry and how it could be used to make corned beef hash in bulk that would feed a big family.

Plus, of course, my grandad was an allotment owner and grew his own potatoes and carrots. Therefore, the only ingredient that would come from their grocery spend would be the tin of corned beef.

A cheap family dinner winner, that everyone loves.


What Is Corned Beef Hash?

Corned beef hash is traditional old school recipe that became popular during the first and second world war as it was easy to make during rationing.

Old school corned beef hash is made out of cans of corned beef, potatoes, carrots, and sometimes other root vegetables too. It is also common to have butter in your corned beef hash.

Because it is a hash and not a stew, it doesn’t have a gravy to it and is perfect for an easy one pot cheap dinner.  

Does Corned Beef Hash Need To Be Cooked?

No, it doesn’t. A can of corned beef is already cooked and you can slice it up and make sandwiches with it.

That is also why, when making this corned beef hash slow cooker recipe, that you add corned beef later on in the recipe and not at the beginning.

Best Way To Cook Corned Beef Hash?

There is no greater way to cook corned beef hash, than in the slow cooker. You can dump in the ingredients, let the slow cooker work its magic and come back to your canned corned beef hash recipe.

What is also wonderful, is that you can place your slow cooker on keep warm and then the leftovers from your lunch of corned beef hash, can become your dinner.

Though for leftovers do also check out our corned beef pasties and our corned beef stew.

Corned Beef Hash Ingredients

Corned Beef Hash Ingredients

Corned Beef – It starts with a couple of cans of corned beef. You can use any brand (we used Aldi), though if you want the best results use Princes.

Potatoes – Making corned beef hash is all about the delicious, cubed potatoes. You can go super small or keep them large like roasted potatoes.

Onion – Hash wouldn’t be the same without the diced onion. You can use one onion or two if you prefer it to have a stronger onion taste. You could also sauté the onion first in the slow cooker if you wanted to.

Carrots – Carrots are fantastic for adding a bit of colour to your corned beef hash or for stretching it to feed more people. You can also add swede or parsnips too.

Butter – I love how butter makes a hash taste amazing. I add it with the potatoes, and it melts onto the potatoes as they cook.

Seasoning – There is nothing worse than bland boring canned corned beef hash in the slow cooker. I recommend parsley, salt, and pepper. You can also add extra seasoning at the end if it doesn’t taste like it has enough flavour.

Then for the kitchen gadgets that we have used in this corned beef hash slow cooker recipe, it has just been our Crockpot. We have this one and it does an amazing job and is also ideal for sauteing on the stovetop first.

How To Make Corned Beef Hash With Canned Corned Beef?

corned beef hash step by step
  • Prep. Peel and dice your potatoes, onion, and carrots. Load into the slow cooker with seasonings and mix with your hands.
  • Cook. Next slow cook until the potatoes are almost soft which is about 2 hours.
  • Slice. The last step is to add in sliced corned beef that you have chopped into chunks and stir. Cook for a further 90 minutes before serving.

How Can I Make Canned Corned Beef Hash Better?

How Can I Make Canned Corned Beef Hash Better

If you are looking for best corned beef hash recipe and want to make it even better, then there are a few things you can do.

Butter – Everything tastes better with butter. That is a quote from the food movie Julie Vs Julia. Well, it is true! Adding some small chunks of butter to the tinned corned beef hash will give it the wow factor.

Princes – By using a quality brand of tinned corned beef, can also make a huge difference. We used Aldi though and felt it was a little more fatty compared to Princes.

Seasoning – Starting with well seasoned potatoes can give a fantastic flavour to your corned beef hash and make such a difference.

How Long Do You Cook Corned Beef Hash?

As the corned beef is out of a can and already cooked, you are just needing to cook your potatoes and carrots and any other vegetables you have added in.

On my slow cooker (I have this Crockpot) I found that 3 and a half hours was perfect. BUT I could have made the potato chunks much smaller (I prefer them bigger) and reduced the cook time by about 30 minutes.

Can You Freeze Corned Beef Hash?

Yes, you can. Corned beef hash is perfect for the freezer. In fact, this is my frozen corned beef hash that I saved in a storage container for another meal.

can you freeze corned beef hash

Simply allow it to fully cool down first, then load into a storage container, add the lid, and add a label so you know what it is and freeze.

Then defrost and use the slow cooker to reheat within the next three months.

What To Serve With Corned Beef Hash?

I love a bowl of corned beef hash, just as it is like in the movie The Cinderella Man. Though in our version we eat with cutlery and not with our fingers like Russel Crowe did.

But if you are wanting that amazing side to go with your amazing, corned beef hash, then I would recommend our air fryer pull apart bread or some air fryer suet dumplings.

Optional. You can also add in extra vegetables. I love to add parsnips to mine.

  1. 5 stars
    Wow, took me back to being a child in the 1950’s. Then essential, now comfort food. I have tried to find a recipe and have made many others not as good. Wonderful. A winner thanks.
    ps I didn’t fry the potatoes just sliced them in at the first stage.

  2. Hi. Thanks for the corned beef hash recipe. I assumed you would add some water but It can’t see any added. Is it just cooked in its own steam?

    • Hi Doreen,

      No we did not use any water as our slow cooker at the time was quite new so the non stick was still intact so we knew it would not stick. If you have a older slow cooker then 100 ml of water in with the potatoes would be fine and the potatoes would soak up any liquid after cooking 🙂

  3. I also like the potato part of my Corned Beef Hash to be chuncky, what I refer to as ‘agricultural’, rather than a sort of mashed potato mixture.
    The one possible thing missing from this though are the crispy/burnt bits from the bottom of the Saucepan. I think I shal make this today but I think I will par boil the potatoes first, as I normally do and then finish up in the Slow Cooker the equivalent of your second stage. I will use the Instant Pot in Slow Cooker Mode and it may even give me that crispy finish cos my IP is a bit on the hot side for a slow cooker and I can always finish of with a short Sauté.

  4. I part boiled my potato chunks,carrots and parsnips, this lessens the cooking times somewhat, and left out the onions, until after the children have eaten some..
