Ricotta Cheese (Best Option)
1:1 by volume (e.g., 1 cup ricotta per 1 cup cream cheese)Ricotta cheese works well because it has a similar moisture content and mild dairy flavor, which complements the egg custard base of quiche. Its protein structure helps maintain the filling’s stability during baking.
For best results, choose whole-milk ricotta and briefly whip it to smooth out graininess before mixing into the quiche filling. Avoid watery ricotta by draining excess liquid if necessary.
Compared to cream cheese, ricotta yields a slightly lighter and less dense texture, making the quiche a bit fluffier but still creamy and cohesive.
