This grilled cheese takes the classic comfort sandwich to the next level with a luscious blueberry lemon thyme jam, melted mozzarella, and sharp white cheddar. The combination of sweet, tangy, and savory flavors makes it a perfect brunch treat or an indulgent snack.
For the Blueberry Spread:
Juice of 1 lemon
1/4 cup sugar
1 pint fresh blueberries
1 bundle lemon thyme, tied with kitchen twine
For the Sandwiches:
Flaky sea salt (for finishing, optional)
8 slices sourdough bread, 1/4-inch thick
4 oz mozzarella cheese, shredded
4 oz white cheddar cheese, shredded
4 tbsp butter
Step 1: Make the Blueberry Lemon Thyme Jam
In a 2-quart saucepan, combine blueberries, sugar, lemon juice, and bundled lemon thyme over medium-high heat.
Bring to a boil, then reduce to medium-low and simmer 10 minutes.
Lower heat to low and simmer another 10 minutes, stirring often, until thickened.
Remove and discard the thyme bundle. Allow jam to cool 10 minutes.
Step 2: Assemble the Sandwiches
Lay out 4 slices of bread.
Spread blueberry lemon thyme jam evenly on each slice.
Sprinkle mozzarella and white cheddar over the jam.
Top with the remaining 4 slices of bread.
Step 3: Grill the Sandwiches
Heat a 12-inch skillet over medium heat. Melt 2 tbsp of butter.
Place two sandwiches in the skillet and cover with a lid.
Cook 2–3 minutes per side until bread is golden and cheese is melted.
Repeat with remaining sandwiches.
Optional: sprinkle flaky sea salt on top before serving.
Jam: Simmer the blueberry jam until thick but still spreadable. Too watery, and it can make the bread soggy.
Cheese: Use freshly shredded cheese for the best melt.
Butter: Spread generously on the outside of the bread for golden, crispy edges.
Heat: Cook over medium heat to allow the cheese to melt fully without burning the bread.
Optional finishing touch: Sprinkle flaky sea salt on top before serving for a gourmet touch.
