Preheat the oven to 250 degrees F (120 degrees C). Line a baking sheet with a silicone liner.
Combine brown sugar, maple syrup, oil, and salt in a bowl. Add oats, almonds, pumpkin seeds, and coconut. Mix well until all ingredients are evenly coated.
Pour mixture onto the prepared baking sheet and distribute in an even layer.
Bake in the preheated oven, lightly stirring every 10 to 15 minutes with the tines of a fork, until evenly toasted and golden brown, about 1 hour.
Remove from the oven. Transfer hot granola into a large bowl and mix in currants. Let cool to room temperature, about 30 minutes.
