Line a Dutch oven with parchment paper. This is optional but makes cleanup later easy.
Pour butter, sugar, pecans and half of the syrup into the bottom of the Dutch oven.
Layer the baguette slices over the sugar and butter mixture.
Whisk together eggs, milk, cinnamon, vanilla and pour over the bread.
Place in the refrigerator overnight or for at least 4 hours. Tip: On camping trips in the cooler months, we simply leave the Dutch oven outside (away from animals) in the cold.
Bake over the coals of a campfire for 60 minutes or in an oven at 350 degrees.
Top with remaining syrup and serve.
