- Fresh blueberries: These juicy berries bring a natural sweetness and vibrant color to the jam that defines this dish.

- Mozzarella cheese: Creamy and mild, it complements the cheddar and ensures a luscious cheese pull.

How to Make Crispy Blueberry Grilled Cheese
Step 1: Prepare the Blueberry Lemon Thyme Jam
The heart of this dish is the homemade blueberry lemon thyme jam. Start by combining fresh blueberries, white sugar, lemon juice, and a bundle of lemon thyme in a saucepan over medium-high heat. As the mixture comes to a boil, the flavors mingle and the sugar dissolves, creating a syrupy base. Lower the heat and let it simmer gently for about 20 minutes total, stirring often, so the jam thickens perfectly without burning. Removing the lemon thyme bundle at the end ensures a subtle herbal hint, letting the natural berry flavors shine through. Cooling the jam before assembly helps it set just right and prevents soggy bread later.
Step 2: Assemble the Sandwiches
This is where magic starts to take shape. Lay out your slices of sourdough and spread a generous layer of the cooled blueberry jam onto four slices. Don’t hold back here—the sweet and tangy jam is what makes this Crispy Blueberry Grilled Cheese so unforgettable. Next, sprinkle equal amounts of shredded white cheddar and mozzarella over each jam-covered slice. The cheeses create a rich and creamy layer that contrasts beautifully with the fruity jam. Top each with the remaining bread slices to form sandwiches that are ready to be grilled to perfection.
Step 3: Grill the Sandwiches
Heat your skillet and melt a tablespoon of butter to start creating that iconic golden crust. Place two sandwiches in the pan, cover with a lid to trap heat for even melting, and cook for a few minutes on each side until each side is beautifully browned and the cheese is melted inside. Use medium heat and be patient; this slow and steady process ensures that the cheese oozes deliciously while the bread crisps up just right. Don’t forget to add the remaining butter when cooking the second batch to keep that buttery crispness consistent.
Step 4: Finish and Serve
Once grilled, cut each sandwich in half to showcase the tempting layers inside. Sprinkle flaky sea salt on top to add bursts of flavor and texture, and consider topping with a few fresh lemon thyme leaves for a fragrant, bright finish. This little garnish isn’t just pretty—it adds an aromatic lift that perfectly completes the experience. Serve your Crispy Blueberry Grilled Cheese hot and watch as loved ones marvel at the marriage of flavors and textures with their very first bite.

Make Ahead and Storage
Storing Leftovers
If you happen to have leftovers of this Crispy Blueberry Grilled Cheese, wrap them tightly in parchment paper or foil and store in the refrigerator. Properly stored, they will remain delicious for up to 2 days, though the texture is best fresh.
Freezing
You can freeze assembled but ungrilled sandwiches by wrapping them individually in plastic wrap and aluminum foil. Freeze for up to 1 month. When ready to enjoy, thaw in the refrigerator overnight before grilling as directed to preserve that wonderful crispy texture.
Reheating
For the best results, reheat leftovers in a skillet over medium-low heat with a small pat of butter, pressing gently to crisp the bread anew and melt the cheese inside. Avoid the microwave, which can make it soggy and less appetizing.
FAQs
Can I use frozen blueberries instead of fresh?
Absolutely! While fresh blueberries provide the best texture and flavor, frozen ones work well too. Just thaw and drain any excess liquid before making the jam to keep it from becoming too watery.
What cheeses work best for this sandwich?
The classic combo of white cheddar and mozzarella is ideal because cheddar adds sharpness and flavor, while mozzarella melts smoothly for that perfect gooey texture. Feel free to experiment with other melty cheeses like Monterey Jack or Gruyere for a twist.
Is there a vegetarian version of this recipe?
This Crispy Blueberry Grilled Cheese is naturally vegetarian as written, focusing on cheese and fruit without any meat ingredients, making it a perfect treat for meat-free days.
How do I prevent the bread from getting soggy?
The key is to properly cook the sandwiches over medium heat and to use cooled jam when assembling. The butter helps create a crispy exterior that keeps the bread from soaking up too much moisture.
Can I make the blueberry jam ahead of time?
Yes! The jam can be prepared a day or two in advance and stored in an airtight container in the fridge. This actually allows the flavors to deepen and develop wonderfully.

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.
