The Fontina is non-negotiable here—imported Italian Fontina has the perfect melt and mild nutty flavor. Murray’s Cheese or Eataly carry excellent selections, but most Whole Foods locations stock it too. For prosciutto, look for Parma or San Daniele—thin slices are ideal. The bread should be a good bakery sourdough with a sturdy crust that holds up to grilling.
No Fontina? Gruyère or young Asiago come closest in flavor and melt. Vegetarians can skip the prosciutto entirely or use marinated eggplant slices for a similar salty depth. The Dijon mustard can be swapped for whole-grain or honey mustard—just avoid sweet varieties that might clash with the balsamic. Fresh basil is best, but dried at one-third the amount works in a pinch.
Assemble sandwiches just before grilling to prevent sogginess. Leftovers keep 1-2 days in the fridge, but they’re best fresh. Reheat in a pan to recrispen the bread. The balsamic glaze can be stored at room temperature for up to 6 months.

Step-by-Step Instructions for Italian Grilled Cheese
Master this elevated technique for a sandwich with crisp bread, gooey fontina, and balanced flavors.
Step 1: Prepare the Garlic-Infused Butter Spread
In a small bowl, combine the 0.5 cup unsalted butter with the minced 2 cloves garlic cloves, 0.25 cup fresh basil leaves, 0.5 tsp sea salt, and 0.25 tsp freshly ground black pepper. Mix until the herbs and garlic are evenly distributed throughout the butter.
This compound butter adds layers of aromatic flavor to the sandwich while ensuring the bread toast to a perfect golden brown. The garlic should be finely minced to avoid overpowering the delicate fontina flavor.
Step 2: Assemble the Sandwich Components
Lay out 8 slices sourdough bread and spread each with a thin layer of the garlic butter mixture. On four slices, spread 1 tbsp Dijon mustard evenly. Layer each with 2 oz Fontina Cheese (divided evenly), 1 oz Prosciutto (divided evenly), and a handful of 1 cup arugula (divided evenly).
Top each with another slice of buttered bread, butter-side out. Press down gently to compress the fillings without squeezing them out. The prosciutto should be thin enough to melt slightly into the cheese as it heats.
Step 3: Grill to Perfection
Heat a large skillet or griddle over medium heat. Place the sandwiches in the pan and cook for 3-4 minutes per side until the bread is deep golden brown and the cheese begins to melt. Avoid pressing down with a spatula—this can squeeze out the fillings.
For extra crispness, brush the exterior of each sandwich with 1 tbsp extra-virgin olive oil before flipping. The sandwiches are done when the cheese is fully melted and the bread has developed a crisp, buttery crust.
Step 4: Finish and Serve
Transfer the sandwiches to a cutting board and let them rest for 1-2 minutes to allow the cheese to set slightly. Slice each sandwich diagonally and drizzle with 2 tbsp balsamic glaze, dividing it evenly among all four servings.
The balsamic glaze adds a sweet-tart contrast to the rich, savory fillings. Serve immediately while the bread is still crisp and the cheese is gooey. Each bite should deliver a balance of creamy, salty, and slightly peppery flavors.
Pro Tips For Making Italian Grilled Cheese
- Butter the Outside: Spread a thin, even layer of unsalted butter on the outer sides of the sourdough before grilling—this guarantees a crisp, golden crust without burning the garlic.
- Shred the Fontina: I learned this the hard way—shredding the Fontina instead of slicing it melts faster and more evenly, so you don’t end up with a half-melted mess.
- Skip the Overcrowding: Resist the urge to add too much prosciutto; one or two thin slices per sandwich is plenty, or the cheese won’t bind everything together.
- Press Lightly: Use a spatula to gently press the sandwich as it cooks, but don’t squash it—this helps the cheese adhere to the prosciutto without squeezing all the goodness out.
Make-Ahead Tips for italian grilled cheese
Prep the Butter
Make the garlic-herb butter up to 3 days ahead. Mix 0.5 cup unsalted butter with minced 2 cloves garlic and 0.25 cup fresh basil. Store in an airtight container in the fridge. This saves time on busy days.
Assemble Early
You can assemble the sandwiches 1 hour before cooking. Layer Fontina, prosciutto, and arugula between buttered sourdough, but keep them uncovered. This prevents soggy bread while letting flavors meld. 💡
Freeze for Later
Assembled (uncooked) sandwiches freeze well for 1 month. Wrap each tightly in plastic wrap and place in a freezer bag. Thaw in the fridge overnight before cooking. I do this for quick weeknight meals.
Reheat Properly
Reheat cooked sandwiches in a skillet over medium-low heat for 2-3 minutes per side. Add a pat of butter to revive the crispness. Avoid the microwave—it makes the bread rubbery. 🔥
Store Components Separately
Keep prosciutto and Fontina wrapped tightly in the fridge for up to 5 days. The balsamic glaze stays good at room temperature for 6 months. This ensures fresh ingredients for every batch.
Revive the Crisp
If storing cooked sandwiches, reheat in a pan with a sprinkle of water and cover for 1 minute. The steam revives the bread while keeping the cheese gooey. This trick works every time.
