Ingredients You’ll Need

Gathering these simple but essential ingredients is the first step to crafting your perfect Crispy Blueberry Grilled Cheese. Each component plays a crucial role—the fresh blueberries bring vibrant fruitiness, the cheeses add gooey richness, and the sourdough bread provides that ideal sturdy but tender base for grilling.

Fresh blueberries: The star fruit that delivers natural sweetness and vibrant color to the jam.
White sugar: Balances the tartness of the blueberries and lemon, helping create a luscious jam.
Lemon juice: Adds bright acidity to cut through the sweetness and enhance flavor complexity.
Lemon thyme bundle: Infuses a gentle, aromatic herbal note into the jam.
Sourdough bread, 1/4 inch thick slices: Provides the perfect crusty yet chewy texture to hold everything together.
White cheddar cheese, grated: Offers sharpness to complement the sweet jam.
Mozzarella cheese, shredded: Delivers melty creaminess for that irresistible gooey texture.
Butter: Essential for achieving that crispy, golden exterior on the grilled sandwiches.
Flaky sea salt: A finishing touch that elevates the sandwich with bursts of savory crunch.

How to Make Crispy Blueberry Grilled Cheese

Step 1: Prepare the Blueberry Lemon Thyme Jam

Start by creating the house-made jam, which is the soul of this sandwich. Combine a pint of fresh blueberries, white sugar, freshly squeezed lemon juice, and a small bundle of lemon thyme in a saucepan. Bring the mixture to a lively boil over medium-high heat, then lower the heat to let it simmer gently. Stir often as it thickens for a total of about 20 minutes. This slow simmer allows the flavors to mingle beautifully, while the lemon thyme adds an aromatic complexity that you won’t find in any store-bought jam. Once thickened, remove the thyme bundle and set the jam aside to cool for 10 minutes before assembling the sandwiches.

Step 2: Assemble the Sandwiches

Lay out half of your sourdough slices and generously spread the warm blueberry lemon thyme jam on each. Don’t be shy here; a good amount of jam ensures the perfect sweet and tangy bite every time. Next, sprinkle a blend of grated white cheddar and shredded mozzarella over the jam, combining sharp and creamy cheeses to complement the fruitiness. Finally, top each with the remaining bread slices to form four hearty sandwiches, ready to be grilled to golden perfection.

Step 3: Grill the Sandwiches

Heat a cast iron skillet over medium heat, melting two tablespoons of butter to coat the pan evenly. Place two assembled sandwiches in the skillet and cover with a lid to help the cheeses melt thoroughly. Cook each side for about 2 to 3 minutes, watching closely until the bread turns beautifully golden and the cheese inside becomes irresistibly gooey. Adjust the heat if the bread browns too quickly. After grilling the first two sandwiches, melt the remaining butter and repeat the process with the last two. The butter not only crisps the bread but also adds a rich, nutty flavor that is pure comfort in every mouthful.

Step 4: Finish and Serve

Once grilled, slice each sandwich in half to reveal the inviting layers inside. Sprinkle a pinch of flaky sea salt on top to accentuate the flavors and add a slight crunch. If you have extra lemon thyme, toss a few fresh leaves on each sandwich to impart a wonderful herbal aroma and a pop of color. This finishing touch transforms your Crispy Blueberry Grilled Cheese into a dish worthy of any gathering or an indulgent everyday treat.

How to Serve Crispy Blueberry Grilled Cheese

Garnishes

Fresh lemon thyme leaves are a perfect garnish, lending their subtle citrusy, minty notes that elevate the sandwich’s natural flavors. A light dusting of flaky sea salt adds texture and a savory balance to the sweetness of the jam. For an extra flourish, a light drizzle of honey or a sprinkle of cracked black pepper can offer a delightful twist that will impress anyone you serve.

Side Dishes

This sandwich pairs beautifully with simple, fresh sides that complement but don’t overpower. A crisp green salad dressed with lemon vinaigrette or a handful of baby arugula with olive oil and lemon juice brightens the meal. Creamy tomato soup or a chilled cucumber salad also work wonderfully, rounding out the meal with diverse flavors and textures that keep each bite exciting and balanced.

Creative Ways to Present

Slice your Crispy Blueberry Grilled Cheese into mini sandwiches or wedges for a fun party platter. Serve them alongside small ramekins filled with extra blueberry jam or herb-infused butter for dipping. Layer the colors on a wooden board with fresh berries and thyme sprigs for a rustic, inviting look. These ideas make this already special sandwich an eye-catching centerpiece perfect for casual get-togethers or elegant brunches.

Make Ahead and Storage

Storing Leftovers

If you happen to have any leftovers (which is rare!), allow the sandwiches to cool completely before wrapping them tightly in plastic wrap or foil. Store them in the refrigerator for up to 2 days to retain freshness. The flavors develop even more after resting, but to keep the bread from getting soggy, make sure the jam has been well thickened and cooled before assembling.

Freezing

You can freeze assembled but ungrilled sandwiches by wrapping each tightly in plastic wrap and placing them in a freezer-safe bag. Freeze for up to 1 month. When ready to enjoy, thaw them in the refrigerator overnight. This is perfect for meal prep or quick weekday lunches, allowing you to have that crispy, melty comfort anytime you want.

Reheating

To reheat, avoid the microwave if possible—it can turn the sourdough soggy and the cheese rubbery. Instead, reheat in a skillet over medium heat with a little butter, pressing gently and flipping carefully until the bread crisps up and the cheese melts again. Alternatively, an oven toaster or air fryer set to 350°F (175°C) for about 5 to 7 minutes will do the trick, renewing the texture and flavor of your Crispy Blueberry Grilled Cheese.

FAQs

Can I use frozen blueberries for the jam?

Yes, frozen blueberries work well if fresh are not available. Just be sure to thaw them first and drain any excess liquid to avoid a runny jam. You may need to simmer a bit longer to achieve the perfect jam consistency.

What cheese can I substitute in this recipe?

Feel free to experiment with cheeses that melt well such as fontina, gouda, or Monterey Jack. The key is balancing a sharp cheese with a mild, creamy one to complement the blueberry jam without overpowering it.

Is it possible to make this recipe vegan?

Absolutely! For a vegan Crispy Blueberry Grilled Cheese, use plant-based butter and dairy-free cheese alternatives that melt well. The homemade jam remains the same, ensuring you still get that lovely sweet and tangy flavor.

Can I prepare the jam in advance?

Definitely. The blueberry lemon thyme jam can be made several days ahead and stored covered in the refrigerator. This makes assembling your Crispy Blueberry Grilled Cheese quick and easy when you’re ready to grill.

How can I make the bread extra crispy?

Use plenty of butter in your pan and cook on medium heat to allow the bread to crisp evenly without burning. Also, pressing the sandwich gently with a spatula during cooking helps achieve that coveted golden crust.

Final Thoughts

There is something truly comforting and joyful about the Crispy Blueberry Grilled Cheese, blending unexpected flavors with classic melting cheese and buttery, crunchy bread. I encourage you to give this recipe a try and maybe even make it your own with your favorite cheeses or herbs. Once you do, you’ll understand why this sandwich has captured my heart and taste buds – it’s pure happiness between two slices of bread.

Description

This Crispy Blueberry Grilled Cheese combines the tangy sweetness of homemade blueberry lemon thyme jam with the melty richness of white cheddar and mozzarella cheeses, all sandwiched between golden, buttery sourdough slices. A perfect blend of sweet and savory flavors with a crisp, indulgent bite.

Instructions

Prepare the Blueberry Lemon Thyme Jam: Combine the fresh blueberries, white sugar, lemon juice, and bundled lemon thyme in a 2-quart saucepan over medium-high heat. Bring the mixture to a boil, then reduce to medium-low and simmer for 10 minutes. Lower heat to low and continue simmering for another 10 minutes, stirring often, until the jam thickens. Remove and discard the lemon thyme bundle. Allow the jam to cool for 10 minutes before using.
Assemble the Sandwiches: Lay out 4 slices of sourdough bread. Evenly spread the blueberry lemon thyme jam onto each slice. Generously sprinkle shredded white cheddar and mozzarella cheeses over the jam. Top with the remaining 4 slices of bread to form sandwiches.
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 for another 2-3 minutes until the bread is golden and the cheese is melted. Adjust heat to prevent burning. Transfer cooked sandwiches to a cutting board, add remaining 2 tablespoons of butter to the skillet, and repeat with the last two sandwiches.
Finish and Serve: Cut each sandwich in half. Sprinkle with flaky sea salt and garnish with extra lemon thyme leaves if desired for an aromatic finish. Serve warm for the best combination of crispy bread and melted cheese balanced by the sweet, tangy jam.
