Yes, here’s how you can make this recipe in the crockpot:
1. If your meatballs are not pre-cooked, you can brown them in a skillet before transferring them to the slow cooker. This step helps to develop flavor and texture.

2. Place the pre-cooked meatballs in the slow cooker. Pour the beef broth over the meatballs.

3. In a separate bowl, whisk together the all-purpose flour and milk until smooth. Pour this mixture into the slow cooker over the meatballs and beef broth.

4. Add salt and pepper to taste. Stir everything gently to combine.

5. Cooking: Cover the slow cooker and cook on low for 4-6 hours or on high for 2-3 hours. Cooking times may vary depending on your slow cooker model and the size of your meatballs.

6. About 30 minutes before serving, check the consistency of the sauce. If it’s too thin, you can mix additional flour with a small amount of cold water until smooth, then gradually stir it into the slow cooker. Let it cook for another 20-30 minutes to thicken.

7. Optional Butter: If desired, you can add the optional butter for a richer gravy. Stir it into the sauce until melted.
