Wash baby potatoes and add to the meat. Add peeled carrots, i just added baby carrots. Open Lipton onion soup mix and pour on top of the vegetables. Now add 1 cup of water and that's pretty much it!

Slow cooker recipes, like this winner, do not require marinating the meat beforehand. Because the steak cooks for hours on low heat, the meat is infused with flavor basically the same as it would be if marinated.
Oh yes, steak can overcook in a crock pot. If left too long the meat with become tough and chewy. Check the internal temperature on the low end of the recommended cooking time.
Keep a close eye on the steak, and when it hits 130 degrees turn off the crock. The meat will continue to cook as it sits and will quickly hit 145 to 155 degrees, which is considered medium and therefore safe to consume.

"....thaw on the counter for a few hours...." YES, by all means do this if you want to get sick. Food safety experts are strongly and universally against this.

it usually applies to big pieces of meat or a whole bird ( like whole turkey for Thanksgiving), when the outside is thawed but still frozen inside. When you defrost a small 1-2 lb piece it will be completely thawed in couple hours and will not have enough time to spoil. Just avoid leaving the meat out for extended periods. Hope it helps.
