Gather all the ingredients.
In a medium saucepan, combine sugar, water, and salt over medium heat.
Stir until the sugar dissolves completely.
Add the pecans to the saucepan.
Stir continuously to coat the pecans evenly.
Continue cooking for about 10 minutes until the mixture thickens.
Remove from heat and stir in vanilla extract and cinnamon.
Spread the pecans on a baking sheet lined with parchment paper.
Let them cool completely, about 30 minutes.
Once cool, break apart any clusters and enjoy!
