Ingredients

Servings: 6
Prep Time: 10 minutes
Cook Time: 8–10 hours on LOW or 4–5 hours on HIGH

• 3 to 3½ pounds bone-in beef cross-cut shanks
• 2 cans (10.5 ounces each) condensed French onion soup
• 1 packet (1 ounce) dry brown gravy mix

Instructions

1. Prepare the beef.
Pat the beef shanks dry with paper towels. Arrange them in an even layer at the bottom of a 5- to 7-quart slow cooker.

2. Mix the gravy base.
In a medium bowl, whisk together the condensed French onion soup and brown gravy mix until well combined.

3. Add the sauce.
Pour the mixture evenly over the beef shanks, coating the meat as thoroughly as possible.

4. Slow cook until tender.
Cover and cook on LOW for 8–10 hours or HIGH for 4–5 hours, until the beef is fork-tender and easily separates from the bone. Cooking time may vary depending on the thickness of the shanks and your slow cooker.

5. Finish the gravy.
Skim excess fat from the surface if desired. Taste the sauce before adding salt, as the soup and gravy mix may already contain plenty of seasoning.

6. Serve and enjoy.
Serve the beef shanks whole or remove the bones and shred the meat. Spoon the rich gravy over each portion and serve warm.

Best Ways to Serve Slow Cooker Beef Shanks

• Creamy mashed potatoes to soak up the savory gravy.
• Buttered egg noodles for a classic comfort-food dinner.
• Steamed white rice for a simple, satisfying meal.
• Roasted carrots or green beans for a colorful vegetable side.
• Warm dinner rolls or crusty bread for dipping into the sauce.

Helpful Cooking Tips

• Use thawed beef: Start with fully thawed beef shanks for more even cooking in the slow cooker.
• Keep the lid closed: Opening the lid frequently releases heat and can extend the cooking time.
• Make thicker gravy: Mix 1 tablespoon of cornstarch with 1 tablespoon of cold water until smooth. Stir it into the hot cooking liquid and cook until thickened.
• Prefer milder flavors? Replace one can of French onion soup with condensed beef broth for a less pronounced onion flavor.
• Make serving easier: Remove the bones and any large pieces of fat after cooking, then return the tender beef to the gravy.
• Avoid excess salt: Taste the finished sauce before adding additional seasoning.

Storage and Food Safety

Refrigerate leftover beef and gravy in shallow, airtight containers within 2 hours of cooking. Store in the refrigerator for 3–4 days or freeze for longer storage. Reheat leftovers to an internal temperature of 165°F (74°C).

Frequently Asked Questions

Can I cook beef shanks in a slow cooker all day?

Yes. Cooking on LOW for 8–10 hours generally produces tender beef shanks. Check that the meat is fork-tender before serving.

Can I use boneless beef instead?

Yes. Boneless beef suitable for slow cooking can work, although the cooking time may differ and the finished sauce may have a slightly different flavor.

How do I know when beef shanks are done?

The meat should be very tender and pull away easily from the bone. If it is still tough, continue cooking and check again later.

Can I make this recipe ahead of time?

Yes. Cook the beef in advance, refrigerate it promptly, and reheat it thoroughly with the gravy before serving.
