Ingredients for Blueberry Grilled Cheese Sandwich
To make these sandwiches, you’ll need:
- 12 oz. fresh blueberries
- 2 Tbsp. fresh lemon juice

How to Make Blueberry Grilled Cheese Sandwich
Make the blueberry filling
Combine blueberries, lemon juice, lemon zest, and thyme in a medium saucepan. Bring it to a boil over medium-high heat, then drop the heat to medium. Simmer, stirring now and then, until thickened about 20 minutes.
This is where it comes together.
Let it cool and preheat the oven
Take the blueberry mixture off the heat and let it cool for 15 minutes. While that’s happening, set your oven to 375°F.
Now it starts to smell amazing.
Toast the bread slices
Once your blueberries are ready, preheat a large skillet over high heat. Butter one side of each bread slice and place them, butter side down, on the skillet. Cook 1–2 minutes, just until the bottoms are golden. Do not flip. Move the slices, toasted side down, onto an ungreased baking sheet.
Assemble the sandwiches
Spread a thin layer of mascarpone on each bread slice, then spoon on about 2 tablespoons of the blueberry mixture. Finish with Brie slices on top of the berries.
Bake until melty
Bake the sandwiches for about 10 minutes, or until the cheese is beautifully melted. Once done, remove from the oven and plate them up.
Add honey and arugula (optional)
If you like, drizzle honey over the top and finish with a handful of fresh baby arugula. Serve immediately no one likes cold cheese!
