All-Purpose Flour (Best Option)
1:1 by volumeAll-purpose flour contains a moderate protein content (around 10-12%) which is sufficient to provide the gluten structure needed to bind the eggs and other ingredients in a frittata. This helps the frittata hold its shape and gives a pleasant, slightly firm texture.
When using all-purpose flour, ensure it is well incorporated to avoid lumps. The slightly lower protein content compared to bread flour means the frittata may be a bit less chewy but still structurally sound.
The final frittata will be tender with a good balance of firmness and softness, closely resembling the original made with bread flour.
