A light and refreshing no-bake lemon pie with a rich mascarpone and whipped cream filling, set in a graham cracker crust. Perfect for warm weather and easy to prepare ahead.
Chilling the mixing bowl and beaters helps whip cream faster and hold stiff peaks better., Keep mascarpone cheese cold to avoid a grainy texture and ensure proper firmness., Whip heavy cream to very stiff peaks before adding mascarpone to prevent a loose filling., Add lemon mixture in portions gently folding to maintain airiness in the filling., For a firmer crust, bake for 8–10 minutes; for a softer base, press and chill without baking., To achieve clean slices, chill the pie thoroughly and run a sharp knife under hot water before slicing., Gel or paste food coloring recommended for vivid yellow filling; liquid coloring may thin the filling., Pie can be made a day ahead; keep covered in fridge and consume within 3 days for best quality., Freezing is not ideal due to texture changes but can be done up to one month with freezing and thawing notes., Variations include adding lemon curd layer, berry swirls, alternative crusts, lime substitutions, or limoncello for an adult twist.
