Heat oil in a large skillet over medium heat. When shimmering hot, add the baguette slices in a single layer. Cook until the underside is golden (about 2 minutes) then flip over, sprinkle with sea salt, and use tongs to transfer to a plate (the second side won’t get as toasted).
Spread the nicely-toasted side of each crostini with 1 tbsp goat cheese, about 1 tsp pomegranate arils, and a scant teaspoon of chopped pistachios. Repeat with remaining baguette slices and scatter with mint leaves, if using.

Notes
Note: Serve within 1 hour for best results, so the bread stays crisp and the pomegranate juice doesn’t seep into the cheese.
