# What You'll Need:
→ Bread
01 - 4 slices sourdough bread or artisan bread
→ Cheese
02 - 4.2 oz Gruyère cheese, grated or thinly sliced
→ Spreads & Oils
03 - 2 tablespoons unsalted butter, softened
04 - 1 to 2 teaspoons truffle oil, white or black
→ Seasoning
05 - Freshly ground black pepper to taste
06 - Pinch of sea salt, optional
# How to Make It:
01 - Lay out all bread slices and spread a thin layer of softened butter on one side of each slice.
02 - Flip the bread over and drizzle truffle oil on the unbuttered side of two slices.
03 - Evenly distribute Gruyère cheese over the truffle oil-drizzled bread slices. Season lightly with black pepper and salt if desired.
04 - Top each cheese-layered slice with a remaining bread slice, positioning the buttered side facing outward.
05 - Heat a non-stick skillet or grill pan over medium-low heat.
06 - Place assembled sandwiches in the pan and cook 3 to 4 minutes per side, pressing gently, until bread is golden brown and crispy and cheese is fully melted. Reduce heat if bread browns too quickly before cheese melts.
07 - Remove from pan and let rest 1 minute. Slice diagonally and serve immediately.
