Slow Cooker Steak Mac and Cheese

We originally shared this leftover steak mac and cheese recipe in early 2018 and decided to update it for you today and make it into slow cooker steak mac and cheese. We hope you like the updated version.

But I have something even better than our steak mac and cheese for you to check out first.

It is our slow cooker ecookbook. It includes all our popular British slow cooker recipes and fantastic for variety with cooking with the Crockpot. Or browse our site as we have plenty of slow cooker recipes that are easy to recreate at home and we have been showing people how to use the slow cooker since 2011.

One Pot Steak Mac And Cheese

When I originally shared my one pot mac and cheese recipe with you, it was never a planned recipe.

We had been grocery shopping and picked up some reduced price, clearance sticker frying steak and a cheap bag of macaroni. The price of the two items was less than $2.00.

Here is the original picture I took of them three years ago:

The idea was that I could slice up the steak, cook the pasta and then add in some cheese and wine from the pantry. It would make a great cheap family dinner.

Plus, it was absolutely delicious too ????

I often do this when I am cooking. Get as many clearance deals as I can find and then make something yummy and reheat the leftovers.

There are many family meals that I make that cost less than $0.50 per person. If memory serves me correctly this original one pot steak mac and cheese cost just $3 or because we had leftovers from our leftovers it worked out at $0.30 per serving.

When I was making our no boil slow cooker mac and cheese, we had leftovers and instead of making steak mac and cheese, we wanted to show you today how to repurpose your leftovers to make an alternative meaty macaroni dish.

Leftover Steak Mac And Cheese

I have two main ingredients that I am using today:

Leftover mac and cheese – Its amazing how quickly mac and cheese fills you up and us Milner’s always have plenty leftover. You can put them to one side and use them in a leftover meal. ~

Spare Steak – I often cook steak in the air fryer and end up with a slice that is too long and will trim the end off. I often also end up with some steak that I didn’t use up (usually braising) and will put it together in a freezer bag and use it in this recipe when I have enough.

Then this can be paired with regular mac and cheese ingredients such as macaroni, garlic, plenty of cheese and your favourite seasonings.  

What I do find, is when I make a leftover mac and cheese, that every ingredient I have in and I use what I already have.

It is also a fantastic opportunity to clear out your fridge and use up your leftovers.

Does Steak Go With Mac And Cheese?

Yes, it does. Steak and mac and cheese are meant to be together. The steak gives fantastic flavour to the macaroni cheese and you can cook them together easily in the slow cooker.

You can also follow our slow cooker mac and cheese recipe and just add in steak if you don’t have leftover pasta to use up.

    • Hi Jim

      If a round steak is a cheap cut and cut quite thinly then yes it could be like a round steak.

      Kind Regards
