Pour the mixture into the partially baked crust, spreading it evenly. Bake for another 20-25 minutes at 350 degrees until the center is set but slightly jiggly adapt by using egg substitutes for vegan preferences or reducing sugar for a lighter version, ensuring your lemon tart remains tangy and consistent.

Fourth Step: Cool and Chill Remove the tart from the oven and let it cool on a wire rack for 30 minutes, then refrigerate for at least 2 hours to firm up the filling this chilling helps the flavors meld and sets the structure.
