This recipe cooks for 2 to 4 hours in the crockpot depending on if you cook on high or low. Either way, I have found that slow cooking this cut of beef makes it come out nice and tender.

    1. I know, Kristen. I’m apparently behind in the flat iron steak world too. When I was researching how to cook it, I was surprised at how many people already knew. It was my daughter who told me about it.

  1. Looks delish! I want to try this out. I love all your recipes; you seem to be a great cook! I can tell from the looks of the recipes you share and from the pecan glazed green beans that I have tried!

    1. Zan, I’m so glad you enjoyed the pecan glazed green beans ๐Ÿ™‚ I don’t cook every day but I have been cooking for over 36 years now. I love reading recipes and learning new good things to cook! I have a nice cookbook collection and enjoy reading through them also! Thanks for the compliment ๐Ÿ™‚

  2. I’m always looking for new slow cooker recipes to cook for the family while at church on Sunday. We’ve grown too much to eat out after church! This one certainly fits the bill and my family will love it! Pinning!

  3. Steak and onions, nothing better. This sounds great! I am always looking for new crock pot recipes. This is getting pinned for the next time flat iron steak goes on sale. And if it doesn’t soon I may try it on a round steak. YUM!

We enjoying hearing from you!
