Don't let a full schedule prevent you from having nourishing meals on the table. Toss everything into the slow cooker, and you have a hearty dinner ready 8 hours later!
Add onions, carrots, steak, mushrooms, and red potatoes into the slow cooker.
Whisk together balsamic vinegar, honey, beef broth, Worcestershire sauce, and salt. Pour over steak and veggies. Add in rosemary sprigs, if using. Cover and cook on Low for 6-8 hours, stirring halfway through cook time (if possible).
