Recipe Overview

• Prep Time: 15 minutes
• Cook Time: 12-19 minutes
• Total Time: 27-34 minutes
• Servings: 2
• Dietary Type: Vegetarian

Ingredients

• 1 tablespoon butter
• 1 tablespoon olive oil
• 1 small onion, sliced
• 8 ounces cremini mushrooms, sliced
• 2 garlic cloves, chopped
• 1 teaspoon thyme, chopped
• ¼ cup white wine (or ¼ cup broth)
• Salt and pepper to taste
• 1 tablespoon parsley, chopped
• ½ teaspoon truffle oil (optional)
• 1 cup fontina (or 1 cup gruyere), shredded
• ¼ cup parmigiano-reggiano cheese, grated
• 4 slices bread (sourdough or a sturdy white bread recommended)
• 2 tablespoons butter

Equipment Needed

• Large skillet
• Cutting board
• Sharp knife
• Cheese grater
• Spatula

Instructions

1. Begin by preparing the mushroom mixture. In a large skillet, melt 1 tablespoon of butter and heat 1 tablespoon of olive oil over medium heat. The combination of butter and oil adds richness and prevents the butter from burning.
2. Add the sliced onion to the skillet and sauté until tender and translucent, about 5-7 minutes. Stir occasionally to ensure even cooking and prevent burning.
3. Add the chopped garlic and thyme to the softened onions. Sauté until fragrant, about a minute, being careful not to burn the garlic. This infuses the oil with aromatic flavors.
4. Introduce the sliced cremini mushrooms to the pan. Sauté until they begin to caramelize and turn golden brown, approximately 10-15 minutes. Stir frequently. The mushrooms will release their moisture, so continue cooking until the liquid evaporates and they start to brown. This caramelization is key to developing their deep, savory flavor.
5. Pour in the ¼ cup of white wine (or broth, if preferred). Deglaze the pan by scraping up any browned bits from the bottom. Cook until most of the liquid has evaporated, about 2-3 minutes. The wine adds a layer of acidity and complexity, while the deglazing process enhances the overall flavor of the mushroom mixture.
6. Season the mushroom mixture with salt and pepper to taste. Add the chopped parsley and remove the pan from the heat. Allow the mixture to cool slightly.
7. If using, stir in the ½ teaspoon of truffle oil into the cooled mushroom mixture. Truffle oil adds a luxurious, earthy note that elevates the sandwich, but it’s entirely optional.
8. In a separate bowl, combine the shredded fontina (or gruyere) and grated parmigiano-reggiano cheese. Mix well. These cheeses provide a blend of creamy, nutty, and sharp flavors that complement the mushrooms perfectly.
9. Gently mix the cheese into the cooled mushroom mixture, ensuring it’s evenly distributed.
10. Butter one side of each of the 4 slices of bread with the remaining 2 tablespoons of butter. This butter will create a golden, crispy crust on the grilled cheese.
11. Place 2 slices of bread in the skillet, buttered side down.
12. Top each slice of bread with half of the mushroom and cheese mixture, spreading it evenly.
13. Cover each with the remaining slices of bread, buttered side up.
14. Grill the sandwiches over medium heat until the cheese has melted and the bread is golden brown, about 2-4 minutes per side. Use a spatula to gently press down on the sandwiches to ensure even cooking and melting of the cheese.
15. Remove from the pan and serve immediately.

Expert Tips & Tricks

• Mushroom Variety: Feel free to experiment with different types of mushrooms! Shiitake, oyster, or even a wild mushroom blend would add exciting new dimensions to this grilled cheese.
• Cheese Choices: If you can’t find fontina or gruyere, provolone or mozzarella would work well as substitutes. Consider adding a touch of smoked gouda for a smoky flavor profile.
• Bread Matters: A sturdy bread like sourdough or a thick-cut white bread is ideal for holding the filling without becoming soggy. Avoid thin, flimsy bread that will fall apart.
• Caramelizing Onions: Take your time caramelizing the onions properly. Low and slow cooking brings out their natural sweetness and depth of flavor.
• Even Cooking: For even cooking, make sure your pan is evenly heated. If you notice one area is browning faster than another, adjust the heat accordingly.
• Pressing Matters: Gently pressing down on the sandwich while it cooks helps the cheese melt evenly and the bread crisp up.
• Make Ahead: The mushroom mixture can be made a day or two in advance and stored in the refrigerator. This makes assembling the grilled cheese quick and easy when you’re ready to eat.
• Truffle Oil Caution: Truffle oil can be overpowering, so use it sparingly. A little goes a long way!

Serving & Storage Suggestions

Serve your Mushroom Grilled Cheese immediately while it’s hot and the cheese is gloriously melted. Cut it in half and present it with the golden-brown crust facing upwards.

Leftover grilled cheese is best enjoyed immediately, but if you must store it, wrap it tightly in plastic wrap and refrigerate it for up to 24 hours. Reheat it in a skillet over low heat or in a toaster oven to regain some of its crispness. Microwaving is not recommended as it will make the bread soggy.

This grilled cheese is a complete meal on its own, but it also pairs well with:

• A simple green salad with a vinaigrette dressing
• A bowl of creamy tomato soup
• Pickled vegetables or a side of coleslaw
• A crisp, dry white wine like Sauvignon Blanc or Pinot Grigio
