How To Make Gourmet Grilled Cheese
Step 1: Butter the outside of both slices of sourdough bread. Spread the herbed mayo on the inside of the bread slices. Layer caramelized onions.
Step 2: Add Gruyère, arugula, and Gouda between the unbuttered sides. Top with the second slice, buttered side facing out.
Step 3: Place the sandwich buttered side down in a non-stick frying pan over medium-low heat.
Step 4: Cook slowly for 6-7 minutes per side, pressing gently if needed, until both sides are golden brown and crisp, and the cheese has fully melted.
Quick Tips To Make This Gourmet Grilled Cheese

- Press gently while cooking to help everything melt together.
- Use pre-made caramelized onions to save time, or make a batch ahead.
- Slice right after cooking for the best texture and melt

- Add a few thin apple or pear slices inside for a sweet contrast that works really well with Gruyère.
