Gather all ingredients.

Mix cranberries, brown sugar, orange juice, orange zest, and cinnamon stick together in a saucepan; bring to a boil.

Reduce heat and simmer until cranberries pop and sauce is thickened, about 15 minutes.

For best results, transfer cranberry sauce to a bowl and refrigerate until chilled, at least 1 hour.

Remove cinnamon stick from sauce and serve at room temperature.
