Ingredients
Here’s what you’ll need to create this irresistible sandwich:

- 1 teaspoon fresh sage, chopped – optional but adds an aromatic touch.
- 4 slices sourdough bread – sturdy enough to hold the filling and get a crisp crust.
- 4 slices gouda cheese – sharp gouda melts beautifully and balances the sweetness.
- 4 slices fontina cheese – creamy, smooth melt for that gooey texture.
- 4 thin slices of prosciutto – adds a salty crunch that elevates the sandwich.
- 1 small apple, thinly sliced – crisp and tart apples complement the savory flavors.

How to Make French Onion and Apple Grilled Cheese
Caramelize the Onions
Heat olive oil in a skillet over medium heat, then add sliced onions. Cook slowly until they turn golden brown and soft, about 15 minutes. Pour in apple cider, stir, and let it reduce slightly for deep, rich flavor.
Prepare the Other Ingredients
While onions cook, thinly slice the apple and cheese. Crisp up prosciutto in a separate pan until lightly golden. This layering of textures makes the sandwich extra special.
Assemble the Sandwich
Butter the outside of each bread slice. Layer gouda, fontina, caramelized onions, apple slices, and crispy prosciutto between the bread. Press lightly to secure the ingredients.
Cook the Sandwich
Place the sandwich in a preheated skillet over medium heat. Grill until the bread is golden and the cheese melts, about 3–4 minutes per side. Flip carefully for an even, crispy finish.
Serve Warm
Slice the sandwich diagonally and serve immediately for the best gooey texture. The flavors are at their peak when hot.
Additional Tips for Making this Recipe Better
- I always use fresh cheese and grate it myself for the best melt.
- Make sure onions are fully caramelized; it brings out their natural sweetness.
- Don’t overcrowd the pan when crisping prosciutto; it needs space to get crispy.
- I like to press the sandwich slightly with a spatula to ensure even grilling.
- Slice the apple very thinly so it softens slightly without losing crunch.
How to Serve French Onion and Apple Grilled Cheese
Serve this sandwich with a side salad, roasted vegetables, or a warm bowl of tomato soup. For presentation, sprinkle a little fresh thyme on top and serve on a wooden board for a rustic touch. The layers should be visible to show off the gooey cheese and caramelized onions.
