Beef Broth (Best Option)
1:1 (1 cup beef broth per 1 cup chicken broth)Beef broth shares a similar umami and savory profile with chicken broth, making it an excellent direct substitute in meatballs where meat flavor is paramount. The gelatin and amino acids in beef broth help retain moisture and improve texture.
For best results, use a low-sodium beef broth to control salt levels and avoid overpowering the chicken or pork flavors in the meatballs. Heat the broth before adding to ensure even mixing.
Compared to chicken broth, beef broth may impart a slightly deeper flavor, which can enrich the overall taste but may shift the flavor profile toward a beefier note, which is usually desirable in meatballs.
