This 5-ingredient slow cooker beef is the kind of practical dinner that earns a regular place in a busy cook’s rotation: minimal prep, deeply savory flavor, and tender meat that develops beautifully over a long, gentle cook. Beef shank is an economical cut with plenty of connective tissue, so the slow cooker is a natural match, turning those frozen slices into a rich, spoon-tender meal with very little hands-on work.
Serve this beef over mashed potatoes, buttered egg noodles, rice, or creamy polenta to catch the flavorful juices. A simple green vegetable such as steamed green beans, roasted carrots, or a crisp salad balances the richness nicely, and a piece of crusty bread on the side is always welcome for soaking up the broth.
5-Ingredient Slow Cooker Beef Shank
Servings: 4 to 6
Ingredients
2 1/2 to 3 pounds frozen raw beef shank slices
1 medium onion, thinly sliced
1 packet onion soup mix (about 1 ounce)
2 cups low-sodium beef broth
1 tablespoon Worcestershire sauce
Directions
1. Scatter the sliced onion across the bottom of the slow cooker, then place the frozen beef shank slices on top in an even layer.
2. Sprinkle the onion soup mix evenly over the beef, then pour in the beef broth and Worcestershire sauce around and over the meat.
3. Cover and cook on low for 8 to 10 hours or on high for 5 to 6 hours, until the beef is very tender and easily pulls apart with a fork.
4. Carefully remove the beef from the slow cooker, spoon some of the onions and broth over the top, and serve hot with your choice of side.
Variations & Tips
Thicker sauce: If you prefer more of a gravy than a broth, transfer the cooking liquid to a saucepan after the beef is done and simmer it with a cornstarch slurry until lightly thickened.
Extra savory depth: A spoonful of tomato paste or a few minced garlic cloves can be added with the broth for a slightly deeper, more rounded flavor while still keeping the recipe very simple.
Make it onion-forward: Use two onions instead of one if you enjoy lots of soft, sweet onions in the finished dish. They melt down as the beef cooks and enrich the broth nicely.
Cooking note: For best results, make sure the beef reaches a safe, fully cooked temperature and becomes fork-tender before serving. Because slow cookers vary, check near the end of the cooking time and add a bit more time if the shank still feels firm.
