Ingredients

Scale

For the Blueberry Lemon Thyme Jam

  • 1 pint fresh blueberries
  • 1/4 cup sugar
  • Juice of 1 lemon
  • 1 bundle lemon thyme, tied with kitchen twine

For the Sandwiches

  • 8 slices sourdough bread, 1/4-inch thick
  • 4 oz mozzarella cheese, shredded
  • 4 oz white cheddar cheese, grated
  • 4 tbsp unsalted butter (such as Kerrygold)
  • Flaky sea salt, for finishing

Instructions

  1. Prepare the Blueberry Lemon Thyme Jam: In a 2-quart saucepan over medium-high heat, combine fresh blueberries, sugar, lemon juice, and the tied lemon thyme bundle. Bring to a boil, then reduce heat to medium-low and simmer for 10 minutes. Lower heat to low and continue simmering for another 10 minutes, stirring often until thickened. Remove and discard the lemon thyme bundle. Let the jam cool for 10 minutes before using.
  2. Assemble the Sandwiches: Lay out 4 slices of sourdough bread. Spread a generous amount of the blueberry lemon thyme jam evenly on each slice. Sprinkle shredded white cheddar and mozzarella cheese over the jam, then top with the remaining 4 bread slices to form sandwiches.
  3. Grill the Sandwiches: Heat a 12-inch cast iron skillet over medium heat and melt 2 tablespoons of butter. Place two sandwiches in the skillet and cover with a lid. Cook for 2-3 minutes until the bottom is golden, then flip and cook another 2-3 minutes until the bread is golden and cheese melted. Adjust heat to avoid burning. Remove sandwiches and add remaining 2 tablespoons of butter to the skillet. Repeat with the remaining sandwiches.
  4. Finish and Serve: Cut each sandwich in half. Sprinkle with flaky sea salt and fresh lemon thyme leaves if desired for an aromatic and flavorful finish. Serve warm and enjoy.

Notes

  • Be generous with the blueberry jam for a balanced sweet and tangy flavor.
  • Use a cast iron skillet for even heat and a perfectly crispy crust.
  • Adjust the heat as needed to prevent burning the bread.
  • Fresh lemon thyme adds a fragrant herbal note; substitute with regular thyme if unavailable.
  • Serve immediately for the best texture and flavor.
