Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

For the blueberry spread
1 pint fresh blueberries
1/4 cup sugar
Juice of 1 lemon
1 small bundle lemon thyme, tied with kitchen twine

For the sandwiches
8 slices sourdough bread, about 1/4-inch thick
4 ounces mozzarella cheese, shredded
4 ounces white cheddar cheese, grated
4 tablespoons butter
Flaky sea salt, for finishing

Directions

In a medium saucepan over medium heat, combine the blueberries, sugar, lemon juice, and the lemon thyme bundle.
Bring the mixture to a gentle simmer, stirring occasionally. Cook until the blueberries burst and the mixture thickens into a jam-like consistency, about 10–15 minutes.
Remove the thyme bundle and set the blueberry spread aside to cool slightly.
Lay out four slices of sourdough bread. Spread an even layer of the blueberry mixture over each slice.
Sprinkle mozzarella and white cheddar evenly over the blueberry layer.
Top with the remaining slices of bread to form sandwiches.
Heat a skillet over medium-low heat and melt a portion of the butter.
Place the sandwiches in the skillet and cook until the bread is golden brown and crisp, about 2–3 minutes per side, adding more butter as needed.
Once the cheese is fully melted and the bread is crispy, remove from the skillet.
Sprinkle lightly with flaky sea salt, slice, and serve warm.

Servings and timing

Servings: 4 sandwiches

Preparation time: 15 minutes
Cooking time: 20–25 minutes
Total time: Approximately 35–40 minutes

Variations

For a richer flavor, substitute brioche for sourdough.
Try fontina, gouda, or provolone in place of mozzarella for a different melt and taste.
Swap blueberries for blackberries or raspberries for a new fruity twist.
Add a drizzle of honey or balsamic glaze for extra depth.
Include a thin layer of cream cheese for added creaminess.

Storage/Reheating

Store leftover blueberry spread in an airtight container in the refrigerator for up to one week.

Leftover assembled sandwiches can be refrigerated for up to 2 days, though the bread may soften.

To reheat, warm the sandwich in a skillet over low heat or in a 350°F oven for about 8–10 minutes until heated through and crisp again. Avoid microwaving, as it can make the bread soggy.

FAQs

Can I use frozen blueberries instead of fresh?

Yes, frozen blueberries work well. Add them directly to the saucepan and cook slightly longer to allow excess moisture to evaporate.

Do I have to use lemon thyme?

No, regular thyme can be used, or you can substitute a small amount of lemon zest for a similar bright flavor.

What type of bread works best?

Sourdough is ideal because it’s sturdy and crisps beautifully, but brioche or country-style white bread also work well.

How do I prevent the sandwich from becoming soggy?

Make sure the blueberry mixture is thick and not overly watery before assembling the sandwiches. Cook over medium-low heat to allow the bread to crisp slowly.

Can I make the blueberry spread ahead of time?

Yes, the spread can be made several days in advance and stored in the refrigerator until ready to use.

What cheeses melt best for this recipe?

Mozzarella provides stretch, while white cheddar adds sharp flavor. Other good melting cheeses include fontina and provolone.

Is this recipe suitable for brunch?

Absolutely. Its sweet and savory combination makes it perfect alongside salads, soups, or fresh fruit.

Can I make this recipe dairy-free?

You can substitute plant-based butter and dairy-free cheese alternatives to create a dairy-free version.

Can I freeze the blueberry spread?

Yes, the spread can be frozen in an airtight container for up to three months. Thaw in the refrigerator before using.

What pairs well with this sandwich?

It pairs nicely with a light green salad, tomato soup, or a bowl of fresh fruit to balance the richness.
