There’s grilled cheese, and then there’s this grilled cheese: a decadent, flavor-packed Truffle Parmesan Mushroom & Swiss Grilled Cheese Melt. Earthy mushrooms, nutty Swiss, salty Parmesan, and the unmistakable aroma of truffle oil come together between two crispy, buttery slices of bread. This is comfort food with a gourmet twist — easy enough for a weeknight, fancy enough for a dinner party appetizer.
Why I Love This Recipe
It hits every note I want in a grilled cheese: ooey-gooey cheese pull, crispy golden bread, and that hit of umami from sautéed mushrooms and truffle oil that takes it to the next level. It’s indulgent without being overcomplicated. I’ve served this with tomato soup, a side salad, or even cut into small triangles for a cocktail party snack. It never disappoints.
Ingredients
- 2 slices of your choice of bread (sourdough, brioche, or country white all work beautifully)
- 2 tablespoons butter, divided
- 1/2 cup sliced mushrooms (cremini, baby bella, or button)
- 1 teaspoon truffle oil
- 1/4 cup grated Parmesan cheese
- 2 slices Swiss cheese
Ingredient Swaps & Notes
- Bread: Go with sturdy slices that hold up to grilling. Sourdough adds tang, while brioche adds a soft richness.
- Cheese: Swap Swiss for Gruyère if you want an even nuttier flavor. You can also use Fontina or Provolone.
- Mushrooms: Try a mix of wild mushrooms like shiitake or oyster for deeper flavor.
- Truffle Oil: A little goes a long way! White truffle oil is ideal, but black works too. Add more if you’re a truffle fiend.
- Add-ons: A few caramelized onions or baby spinach leaves tucked inside add a new layer of flavor.
Instructions
- Sauté the Mushrooms:
Heat a skillet over medium heat and melt 1 tablespoon of butter. Add sliced mushrooms and cook for 5–7 minutes, until browned and tender. - Truffle Time:
Drizzle truffle oil over the sautéed mushrooms, stir to combine, and set aside. - Prep the Bread:
Butter one side of each bread slice with the remaining butter. - Build the Sandwich:
In the skillet, place one slice of bread butter-side down. Layer with grated Parmesan, Swiss cheese slices, sautéed mushrooms, and top with the second slice of bread, butter-side up. - Grill It Up:
Cook for 3–4 minutes per side over medium heat, pressing gently with a spatula until bread is golden brown and cheese is fully melted. - Serve:
Remove from heat, let it rest for a minute, slice in half, and serve warm.
Tips for Success
- Low and Slow: Don’t rush it! Medium heat gives you the perfect golden crust without burning the bread before the cheese melts.
- Lid Trick: Covering the pan while grilling helps the cheese melt faster.
- Don’t Overstuff: It’s tempting, but too many mushrooms can make the sandwich soggy.
Serving Suggestions and Pairings
- Tomato Basil Soup – the classic pairing never fails.
- Crispy side salad – arugula, lemon vinaigrette, and shaved Parmesan.
- Roasted potatoes or sweet potato fries – for a hearty meal.
- For a party-ready spread, serve it with this Beer Cheese Dip and some sparkling wine or a crisp lager.
Storage & Leftover Tips
- Best Fresh: Like most grilled cheese, this is best enjoyed right off the skillet.
- Reheating: If you do have leftovers, reheat in a skillet over low heat to bring back the crispiness.
- Freezing: Not recommended — the texture of mushrooms and truffle oil doesn’t hold up well after freezing.
