- 8 slices sourdough bread, 1/4 inch thick: Offers a sturdy, textured foundation that crisps brilliantly.
- 4 oz white cheddar, grated: Sharp and flavorful, it adds depth to the cheese blend.

How to Make Crispy Blueberry Grilled Cheese
Step 1: Prepare the Blueberry Lemon Thyme Jam
Start by combining the fresh blueberries, sugar, lemon juice, and your bundle of lemon thyme in a medium saucepan. Bringing this mixture to a boil and then simmering gently allows the flavors to meld and the jam to thicken, creating an irresistible spread. Stir it often to prevent sticking, and when it’s perfectly thickened and aromatic, remove the thyme bundle for a smooth finish.
Step 2: Assemble the Sandwiches
With your jam cooled to just the right temperature, spread a generous layer onto four slices of sourdough. Don’t shy away from being generous here; it’s the sweet and tangy heart of the sandwich. Next, sprinkle the shredded white cheddar and mozzarella evenly over the jam before topping with the remaining bread slices. This layering promises a symphony of textures and flavors once grilled.
Step 3: Grill the Sandwiches to Perfection
Heat your skillet and melt the butter slowly to ensure an even crispy crust. Place your assembled sandwiches in the pan, cover them to trap the heat, and cook until the bread is golden and the cheese melty. Flip carefully and repeat, adjusting the heat to avoid burning. This technique locks in the moisture and blends all the flavors wonderfully, giving you that sought-after Crispy Blueberry Grilled Cheese texture and taste.
Step 4: Finish and Serve
Once grilled, slice each sandwich in half diagonally for maximum melt-to-crust ratio, then sprinkle flaky sea salt and a few extra lemon thyme leaves on top. This final aromatic touch brightens the flavor and makes each bite even more special. Serve immediately to enjoy the perfect balance of crispy, gooey, fruity, and savory components.
How to Serve Crispy Blueberry Grilled Cheese

Garnishes
A simple sprinkle of flaky sea salt atop the sandwich accentuates the sweet and savory flavor contrast wonderfully. Fresh lemon thyme leaves scattered on serve not only add a pop of color but also complement the aromatic profile, creating a sophisticated touch with minimal effort.
Side Dishes
This grilled cheese shines alongside light, fresh salads featuring arugula or baby spinach topped with a vinaigrette to balance richness. For heartier options, tomato soup or roasted root vegetables paired with this sandwich make for an indulgent yet refreshing meal experience.
Creative Ways to Present
Cut your Crispy Blueberry Grilled Cheese into bite-size squares for elegant appetizer platters, or serve stacked with layers of extra jam and cheese for brunch guests. You could also pair it with a dollop of whipped ricotta or mascarpone drizzled with honey to add a creamy dimension that’s truly irresistible.
Make Ahead and Storage
Storing Leftovers
If you have leftovers, wrap them tightly in cling film or foil and store in the refrigerator for up to two days. The sandwich will retain most of its flavors, though you might want to re-crisp the bread before enjoying again.
Freezing
Crispy Blueberry Grilled Cheese sandwiches can be frozen after assembly but before grilling. Wrap each in parchment paper and then foil, and freeze for up to a month. When ready, grill straight from the freezer, adding a few extra minutes to ensure even cooking.
Reheating
To reheat and reclaim that coveted crispy texture, use a skillet over medium-low heat, adding a touch of butter. Avoid the microwave as it can make the bread soggy and the cheese rubbery. A gentle re-grill brings back that fresh-from-the-pan magic.
FAQs
Can I use frozen blueberries for the jam?
Yes, frozen blueberries work well if fresh are not available. Just thaw and drain any excess liquid before cooking to avoid a watery jam.
What cheeses work best in a Crispy Blueberry Grilled Cheese?
White cheddar offers sharpness and flavor depth, while mozzarella provides creamy meltiness. You can experiment with a blend like fontina or gouda, but keep the balance between flavor and melt.
Is sourdough indispensable?
Sourdough’s texture and tang provide a great contrast and structure, but you can substitute with any good quality, sturdy bread like a rustic country loaf or a hearty multigrain.
How do I ensure the sandwich doesn’t become soggy?
Cooking over medium heat and using a lid helps melt the cheese evenly without burning the bread. Also, allow the jam to cool before spreading, which prevents the bread from soaking up moisture.
Can this recipe be made vegan or dairy-free?
You can substitute dairy butter with plant-based spreads and choose vegan cheeses that melt well, though the flavor profile will differ slightly. Also, double-check your bread ingredients to ensure they meet your dietary needs.

- 1/4 cup white sugar
- Juice of 1 lemon
- 1 small bundle lemon thyme, bundled with kitchen twine
For the Sandwiches
- 8 slices sourdough bread, each 1/4 inch thick
- 4 oz white cheddar cheese, grated
- 4 oz whole mozzarella cheese, shredded
- 4 tbsp butter
- Flaky sea salt, for finishing
Instructions
- Prepare the Blueberry Lemon Thyme Jam: Combine fresh blueberries, white sugar, lemon juice, and the bundled lemon thyme in a 2-quart saucepan over medium-high heat. Bring the mixture to a boil, then reduce heat to medium-low and simmer for 10 minutes. Lower heat to low and continue to simmer, stirring frequently, for another 10 minutes until the jam thickens. Remove and discard the lemon thyme bundle, then let the jam cool for 10 minutes before using.
- Assemble the Sandwiches: Lay out 4 slices of sourdough bread. Spread the cooled blueberry lemon thyme jam evenly over each slice. Sprinkle shredded white cheddar and mozzarella cheeses over the jam layer. Top each with the remaining bread slices to form 4 sandwiches. Be generous with the jam to create a nicely sweet and tangy flavor profile.
- Grill the Sandwiches: Heat a 12-inch cast iron skillet over medium heat and melt 2 tablespoons of butter. Place two assembled sandwiches in the skillet and cover with a lid. Cook for 2-3 minutes until the bottom is golden brown. Flip and cook another 2-3 minutes until the other side is golden and the cheese is fully melted. Adjust heat as necessary to avoid burning. Transfer cooked sandwiches to a cutting board, add the remaining 2 tablespoons of butter to the skillet, and repeat the process with the remaining two sandwiches.
- Finish and Serve: Cut each sandwich in half. Sprinkle flaky sea salt and extra fresh lemon thyme leaves on top for a burst of aromatic flavor. Serve warm and enjoy the blend of crispy bread, melty cheese, and fruity jam.
Notes
