Ricotta Cheese (Best Option)
1/4 cup ricotta per 1/4 cup cream cheeseRicotta cheese has a mild flavor and a creamy, slightly grainy texture that mimics cream cheese's moisture content and fat level, which helps maintain the frittata's richness and tenderness. The protein content in ricotta also aids in coagulation with eggs, ensuring a stable structure.
For best results, drain excess whey from ricotta to avoid adding too much moisture, which could make the frittata soggy. Mixing it well with eggs before cooking ensures even distribution.
Compared to cream cheese, ricotta results in a slightly lighter and less dense frittata but preserves the creamy mouthfeel and mild taste, making it the closest match overall.
