What Ingredients are in Melty Fontina Mushroom Panini?
The beauty of this panini lies in its simplicity—just a handful of quality ingredients coming together to create something truly spectacular.
I’m convinced the secret is in the Fontina cheese, which melts into this gloriously gooey, nutty blanket that hugs those savory mushrooms. And don’t get me started on the fresh sage—that herbal note takes this sandwich from good to “can’t-stop-thinking-about-it” territory.
- 4 slices good sandwich bread (preferably whole grain country loaf)
- 1 cup shredded Fontina cheese (adjust to your cheese preference)
- 1 cup sliced mushrooms
- 1 tablespoon fresh chopped sage (or 3/4 teaspoon dried)
- Salt and pepper to taste
- 3 tablespoons butter (divided)
When shopping for these ingredients, the quality really does matter.
Splurging on a nice loaf of bread with a sturdy texture will help your panini hold up to the filling while getting perfectly crisp.
And if you can’t find Fontina? Gruyère or even a mild provolone would work as substitutes, though they’ll each bring their own character to the sandwich.
As for mushrooms, button or cremini are perfect, but wild mushroom blends would add an extra dimension of earthy flavor.
Sometimes the simplest ingredients create the most memorable meals, right?
How to Make this Melty Fontina Mushroom Panini
Let’s start with the mushrooms, which are going to be the star alongside our cheese. In a hot sauté pan, melt 1 tablespoon of butter until it’s sizzling, then add your 1 cup of sliced mushrooms. The key here is to get some nice browning without letting them release too much liquid—we want meaty mushrooms, not soggy ones.
Once they’ve started to brown, sprinkle in that 1 tablespoon of fresh chopped sage (or 3/4 teaspoon dried if that’s what you have), along with salt and pepper to taste. Cook until the mushrooms are soft but still have some texture, then set them aside while we build our panini masterpiece.
Now for the assembly: take your 4 slices of good sandwich bread (that whole grain country loaf will give you the perfect sturdy base) and butter one side of each slice with the remaining 2 tablespoons of butter.
Place two slices in your pan butter-side down, and sprinkle half of your 1 cup of shredded Fontina cheese over them. This first layer of cheese acts like glue, helping hold everything together once melted. Next, divide those fragrant sautéed mushrooms between the two sandwiches, then top with the remaining cheese.
Crown each sandwich with the remaining bread slices, butter-side up, so you’ve got butter on both the top and bottom exterior of the sandwich.
If you’re lucky enough to have a panini press, simply close it over your sandwiches and cook for about 3-4 minutes until golden and the cheese is perfectly melty.
No panini press? No problem. Use a regular skillet over medium-low heat until the bottom is toasty (about 3 minutes), then flip—carefully, no one wants a mushroom avalanche—and press down with another heavy pan or a spatula to get that classic panini compression. For perfectly sliced mushrooms, consider using a professional food processor which can create uniform slices that cook evenly and look beautiful in your sandwich.
Cook for another 2-3 minutes until both sides are golden brown and the cheese is doing that gorgeous stretchy thing when you peek inside. The outside should be crispy, the inside gooey, and the aroma absolutely mouthwatering.
Just let it cool for a minute before cutting, or risk burning your tongue in that classic “too impatient for deliciousness” way we’ve all experienced.
Melty Fontina Mushroom Panini Substitutions and Variations
While Fontina cheese creates the perfect gooey center for this luxurious panini, you’re certainly not locked into using only what the recipe suggests.
Try swapping in Gruyère for a nuttier flavor, or provolone for something milder. Not a mushroom fan? Caramelized onions make a divine alternative.
For herb variations, rosemary or thyme can replace sage beautifully.
And don’t feel bound to plain bread—sourdough, ciabatta, or even rye can transform this sandwich completely.
Want protein? Add prosciutto or thin slices of roasted chicken.
The possibilities? Nearly endless. Your perfect panini awaits.
What to Serve with Melty Fontina Mushroom Panini
Since this rich, cheesy panini stands as a meal centerpiece, I recommend pairing it with lighter sides that balance its decadence.
A simple arugula salad with lemon vinaigrette cuts through the richness perfectly—just toss with olive oil, lemon juice, and a sprinkle of salt.
For something heartier, roasted tomato soup makes a classic companion.
Can you imagine dipping those crispy, cheese-filled corners into warm soup? Divine.
In warmer months, try a cucumber-radish slaw with fresh dill.
The cool crunch provides textural contrast to the melty sandwich.
Sometimes the simplest sides let your panini shine brightest.
