Common Mistakes to Avoid

- Using regular beef broth: Opt for low-sodium beef broth to control salt levels in your meal. This helps maintain a balanced flavor, especially when combined with gravy mix.
- Not whisking ingredients properly: If you don’t mix the broth, gravy mix, and seasonings well, you’ll end up with uneven flavor. Always whisk until smooth before pouring over meatballs.
- Overcooking or undercooking: Cooking times matter! Ensure you follow recommended times for high or low settings to achieve juicy meatballs without drying them out.
