Preheat your oven to 350°F (175°C) and lightly grease a 9-inch pie dish.
In a large bowl, whisk the eggs until smooth. Add the ricotta cheese and stir until combined.
Pour in the honey, cinnamon, flour, vanilla extract, and lemon zest. Mix everything until the batter looks silky and smooth.
Pour the mixture into your prepared pie dish and smooth out the top.
Bake for 40 minutes or until the center is just set and the edges are lightly golden.
Let the pie cool completely. Dust with powdered sugar if using, and top with peach or apple pie filling for a fruity twist.
