Vegetable Broth (Best Option)
1/4 cup per 4 eggsVegetable broth is a plant-based liquid that mimics the savory and umami qualities of chicken broth, making it an excellent alternative in egg dishes like frittatas. It contributes moisture that helps eggs cook evenly and prevents dryness.
When using vegetable broth, choose a low-sodium variety to control salt levels. Heat it slightly before adding to the eggs to ensure even mixing and prevent temperature shock that can affect egg texture.
Compared to chicken broth, vegetable broth produces a similarly flavored frittata with a slightly earthier note but retains the light, fluffy texture expected in this dish.
