In a mixing bowl, combine the Greek yogurt, pumpkin puree, maple syrup, vanilla extract, pumpkin pie spice, and a pinch of salt. Whisk until the mixture is smooth and well combined.
Fold in the chopped pecans gently with a spatula, ensuring they are evenly distributed.
If using an ice cream maker, pour the mixture into the machine and churn according to the manufacturer’s instructions, usually for about 20-25 minutes or until it reaches a soft-serve consistency.
If you don’t have an ice cream maker, pour the mixture into a blender and blend until smooth. Pour it into a freezer-safe container and freeze for 3-4 hours or until firm. Stir the mixture every hour during freezing for better texture if blended.
Once the yogurt is frozen, scoop into bowls and serve immediately, or return to the freezer for longer storage.
Allow the frozen yogurt to sit at room temperature for a few minutes before serving to soften slightly, making it easier to scoop.
Optionally, top with extra pecans or a drizzle of maple syrup before serving for added flavor and texture.
