This onion beef stew recipe uses just 2 ingredients – beef and onions!  When the onions are cooked for a long time with the beef in a slow cooker, they turn into an onion sauce.  You get super-tender beef that melts in your mouth and a delicious onion sauce that you can dunk your bread into!

This onion beef stew is a true slow cooker recipe – all you need is a slow cooker and no other kind of cooking (such as frying pan or oven) is necessary.  Many slow cooker beef stew recipes ask you to brown meat in a frying pan before transferring it to slow cooker – well, not this one.  Making this onion beef stew is as easy as putting cut-up beef and chopped onions directly in a slow cooker and pressing the “Start” button.  There is no excuse on not making this onion beef stew – it’s the easiest and laziest main dish possible :)

  1. No liquid? I notice that neither this recipe nor the beef stew with potatoes and onions mentions any liquid. Is this correct or have you just forgotten to mention water, wine, whatever? I have never cooked dry ingredients in my slow cooker and am intrigued to know if the ingredients will produce the necessary sauce element. Best regards, Elizabeth Caplan

  2. I’m going to try this with what I have on hand lol 1 and 1/2 stew meat and 2 large-ish onions. I think I’ll go low for four hours then add some quartered russets and carrots and turn it up on high for another 2 hours. Here’s hoping!
