How to Make Crispy Blueberry Lemon Thyme Grilled Cheese Sandwich Recipe

Step 1: Prepare the 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. Bring it to a boil, then simmer gently for about 20 minutes, stirring often until the jam thickens to a luscious, spoon-coating consistency. Removing the thyme bundle at the end leaves the jam perfectly infused without overpowering the flavor. Let it cool slightly before moving on.

Step 2: Assemble the Sandwiches

Lay out your slices of sourdough and spread a generous layer of the blueberry lemon thyme jam evenly over half of them — this jam is where the magic starts! Then sprinkle a mixture of shredded white cheddar and mozzarella cheese on top. Cap each with a remaining slice of bread to form your sandwiches, ready to be grilled into golden perfection.

Step 3: Grill the Sandwiches

Heat your skillet and melt a couple tablespoons of butter until it’s shimmering. Add two sandwiches at a time and cover with a lid to trap warmth, helping the cheese melt evenly. After a few minutes, check for a deep golden crust before flipping gently to toast the other side. Add more butter and repeat with the remaining sandwiches. The key is to maintain medium heat so the bread crisps without burning and the cheese melts perfectly.

Step 4: Finish and Serve

Slice each sandwich in half to reveal the gorgeous melted center. Sprinkle with flaky sea salt and, if you like, a few fresh lemon thyme leaves for an aromatic pop. Serve warm to savor the delightful contrast of crispy, melty, sweet, and tangy in every bite.

The image shows a grilled sandwich cut into two triangular halves placed on a white marbled surface. Each sandwich half has a golden-brown toasted crust with a slightly crispy texture on the outside. Inside, there are two visible layers: the bottom layer is a dark purple blueberry filling, and on top of it is a melted creamy white cheese layer that stretches slightly between the halves. Coarse salt crystals and small green sprigs of herbs are sprinkled on top of the sandwich and around it. Fresh blueberries scatter around the sandwich, with two small white bowls — one filled with blueberries and the other with coarse salt — partially visible at the edges.

Garnishes

A light sprinkle of flaky sea salt on top doesn’t just enhance flavor but adds a delicate crunch that complements the crispy bread. Fresh lemon thyme leaves provide a beautiful visual and a fragrant herbal note that pairs perfectly with the sweet-blueberry accents.

Side Dishes

This sandwich pairs wonderfully with a crisp green salad dressed in a simple vinaigrette or a bowl of tomato basil soup for a cozy meal. For a bit of fun contrast, some pickled vegetables or a tangy slaw add brightness and texture alongside the rich grilled cheese.

Creative Ways to Present

Try cutting the sandwiches into quarters and serving them as finger food for brunch or a casual party. Place them on a rustic wooden board with small bowls of extra blueberry jam and fresh herbs to encourage guests to customize each bite. You can even toast the bread with a hint of cinnamon or drizzle honey over the jam for an extra decadent twist.

Make Ahead and Storage

Storing Leftovers

If you have any leftover sandwiches, wrap them tightly in plastic wrap and store them in the refrigerator for up to 2 days. The jam may cause the bread to soften a bit, but you can restore crispiness when reheating.

Freezing

These sandwiches freeze well. To freeze, place individually wrapped sandwiches in a freezer-safe container or bag. They will keep up to 1 month. Thaw in the fridge overnight before reheating for best results.

Reheating

Reheat sandwiches in a skillet over medium heat with a little butter, pressing gently to revive that crispy crust while melting the cheese again. Avoid microwaving if possible—it can make the bread soggy and the jam runny.

FAQs

Can I use frozen blueberries instead of fresh for the jam?

Yes! Frozen blueberries can be used, just be sure to thaw and drain any excess juice before cooking the jam to prevent it from being too watery.

What type of bread works best for this grilled cheese?

Sourdough bread is ideal because it crisps up beautifully and has a slight tang that complements the sweet-tart jam. However, any sturdy bread like country white or rustic Italian will also work.
Can I make the blueberry lemon thyme jam ahead of time?

Absolutely! The jam can be made up to one week in advance and stored in the fridge. It tastes even better after the flavors meld for a day or two.
How do I prevent the grilled cheese from getting soggy?

Cook the sandwich over medium heat and use enough butter to toast the bread evenly. Covering with a lid helps melt the cheese without increasing sogginess, and serving immediately keeps the bread crispy.
