Prep the Meat. Cut steak into 1-inch cubes. Pat dry with paper towels to help them brown better.
(Optional) Sear for Extra Flavor. Heat oil in a skillet over medium-high heat and sear the beef in batches until browned. This step adds flavor but isn’t required.
Load the Crockpot. Add steak bites to your slow cooker. Sprinkle with garlic, onion powder, paprika, salt, and pepper. Pour in beef broth and Worcestershire sauce. Stir to coat evenly.
Cook. Cover and cook on LOW for 4–6 hours or HIGH for 2–3 hours, until the beef is tender and flavorful. Stir occasionally if you're home.
Garnish and Serve. If using fresh herbs, toss them in during the last hour. Serve warm with your favorite sides!
