β Vegetable Broth (Best Fat-Free Option)
1 cup vegetable broth per 1 cup chicken brothVegetable broth contains a blend of simmered vegetables and seasonings that mimic the umami and saltiness of chicken broth, providing a similar depth of flavor and moisture essential for the filling's consistency.
When using vegetable broth, ensure it is well-seasoned but not overly salty to avoid overpowering the dish. Taste the filling before baking and adjust seasoning as needed.
The final dish will be very close to the original in flavor and texture, making it an excellent substitute for those avoiding animal products or seeking a lighter option.
