If browning the meat (this step is optional but recommended), heat olive oil in a large skillet or Dutch oven set over medium to medium-high heat. Add beef cubes and cook 2-3 minutes. Carefully flip each piece using a tong or spatula and continue the process until the meat is browned on all sides. Transfer to the slow cooker.
Combine all ingredients (beef through broth) in a slow cooker set on low.
Cook for 8 hours on low or until beef is tender.
Season with additional salt and pepper as needed. Serve with desired toppings.
