03 - Evenly divide and sprinkle mozzarella, fontina, and cheddar cheese over the pesto-covered slices
04 - Top with remaining bread slices, buttered side facing outward
05 - Heat a large nonstick skillet or griddle over medium heat until ready for cooking

# Expert Tips:

01 -
  • The three-cheese blend creates this ridiculous melt factor that makes every bite feel like a warm hug
  • Pesto adds this bright fresh punch that cuts through all that rich cheese perfectly
  • Sourdough holds up beautifully to grilling without getting soggy or falling apart
02 -
  • Medium heat is your friend here—too hot and you'll burn the bread before the cheese melts, too low and you'll be waiting forever for that crunch
  • Pressing gently with your spatula helps the bread make even contact with the pan, but don't smash it or you'll squeeze out all the cheesy goodness
  • If your cheese isn't melting, you can tent the pan with foil for a minute to trap heat and help things along without burning the bread
03 -
  • Grate your own cheese instead of buying pre-shredded—those anti-caking agents prevent proper melting and you can taste the difference
  • Let your butter come to room temperature before spreading to avoid tearing the sourdough
  • If making multiple sandwiches, keep finished ones warm in a 200°F oven while you finish the batch
