"We all love this!!!! We can't find flank steak but have used chuck roast instead. It is now one of our favorite meals."

"This was great, BUT, added a lot to it. Started with sealing the meat with salt, pepper, garlic sale, pepper before cooking, browned. Then added onions, garlic, & browned. Added water, red wine, & light on other seasoning. When put into crock pot, as cooking, added, red pepper flakes, honey, honey bbq sauce, garlic powder, hot paprika seasoning, Cajun seasoning, more salt & pepper as needed, balsamic vinegar, it was over the top delicious, served with scallop potatoes, but with all the sauce left, will do garlic mashed potatoes next time!!"

"Loved this. We're are a family of 7 and did double flank steak portions and it turned out perfect. Nothing leftover!"

"I thought I'd add to my previous comments, that I ALWAYS cook two flank steaks at the same time...(Yes stacked in the the same crock-pot). Sometimes I double the spices and onion, sometimes I don't...but BOTH always turn out perfect!"
