Add the pecans, maple syrup, cinnamon, and salt to a pot over medium heat.
Bring to a simmer and stir the pecans constantly until the syrup has completely evaporated, about 8 to 10 minutes.
Turn the pecan mixture out onto a parchment-lined baking tray. Try to separate the nuts as much as possible.
Let them cool and dry, at least 10 minutes.
After the mixture has dried, break apart any pecans that are sticking together. Serve or store.
