15-Minute Ultimate Grilled Cheese
This grilled cheese combines sharp cheddar with nutty Gruyere cheese, enhanced with fresh chives and black pepper for a sophisticated twist on the classic comfort food. The cheese mixture is processed until smooth for even melting, while mayonnaise replaces butter on the outside for superior browning and crispiness. Perfect for lunch, dinner, or whenever you crave something indulgent. The sourdough bread provides tangy flavor and sturdy structure that holds up beautifully to the rich cheese filling.

Tips
Let cheese come to room temperature before processing for smoother blending and easier spreading.
Use mayonnaise instead of butter on the bread exterior for better browning and crispier crust.
Allow sandwich to rest briefly after cooking so cheese sets slightly and won't ooze out when cut.
Good to Know
Refrigerate wrapped sandwiches up to 2 days, reheat in skillet over low heat.
Prepare cheese mixture up to 1 day ahead, store covered in refrigerator.
Serve immediately while cheese is melted and bread is crispy hot.
Common Mistakes
Use medium heat to avoid burning bread before cheese melts.
Don't skip resting time or cheese will ooze out when cut.
Apply mayonnaise in thin layer to prevent greasy exterior.

FAQ
Can I make this without a food processor?
Yes, grate both cheeses finely and mix with chives and pepper. The texture won't be as smooth but will still melt well.
What if I don't have Gruyere cheese?
Swiss, fontina, or aged white cheddar work well as substitutes, though the flavor will be slightly different from the original.
How long will leftover sandwiches keep?
Store wrapped in refrigerator up to 2 days. Reheat in skillet over low heat to restore crispiness without burning.
