Sourdough Pesto Grilled Cheese (Printable)

A gourmet take on the classic grilled cheese with thick sourdough, basil pesto, and a melty three-cheese blend grilled to golden perfection.

# What You Need:

→ Bread

01 - 4 slices thick-cut sourdough bread

→ Cheese

02 - 1/2 cup shredded mozzarella cheese
03 - 1/2 cup shredded fontina cheese
04 - 1/2 cup shredded sharp white cheddar cheese

→ Spreads & Condiments

05 - 3 tablespoons basil pesto
06 - 2 tablespoons unsalted butter, softened

# How-To Steps:

01 - Lay out four sourdough slices on a clean work surface. Spread 1/2 tablespoon of softened butter on one side of each slice.
02 - Flip two bread slices and spread approximately 1 tablespoon of basil pesto on the unbuttered side of each. Evenly distribute mozzarella, fontina, and cheddar cheese over the pesto-covered slices, dividing the 1.5 cups total cheese equally between both slices.
03 - Top each cheese-laden slice with one of the remaining bread slices, ensuring the buttered side faces outward for optimal browning.
04 - Place a large nonstick skillet or griddle over medium heat and allow it to reach temperature for approximately 1-2 minutes.
05 - Transfer assembled sandwiches to the preheated skillet. Cook for 3-4 minutes on the first side, applying gentle pressure with a spatula to promote even contact and golden browning. Flip and cook the second side for an additional 3-4 minutes until the bread achieves a golden, crisp exterior and the cheese melts completely.
06 - Remove sandwiches from the skillet and allow them to rest for 1 minute. Slice diagonally and serve immediately while still warm.

# Expert Suggestions:

01 -
  • The pesto adds an herby brightness that cuts through all that rich, gooey cheese
  • Using three different cheeses creates layers of flavor that single-cheese sandwiches just cant match
02 -
  • Low and slow is better than high and fast, medium heat gives the cheese time to melt before the bread burns
  • Shred your own cheese if you can, pre-shredded cheese has anti-caking agents that prevent smooth melting
03 -
  • Use a panini press if you have one, it applies even pressure and creates those gorgeous grill marks
  • Let your cheese come to room temperature before assembling for faster, more even melting
