8 ounces cremini mushrooms, sliced
1 small onion, sliced
1 clove garlic, chopped
1 teaspoon fresh thyme, chopped
1/4 cup white grape juice or broth

Caramelized Mushroom Preparation

Sautéing the Aromatics

Begin extract by heating the 1 tablespoon of butter and 1 tablespoon of olive oil in a large skillet or frying pan over medium heat. Once the butter has melted and the oil is shimmering, add your sliced onion. Cook the onion for about 5-7 minutes, stirring occasionally, untgin extractit begins to soften and turn translucent. This initial sautéing step helps to mellow the onion’s sharpness and build a sweet foundation for our caramelized mushrooms.
Add the sliced cremini mushrooms to the skillet with the softened onions. It might seem like a lot of mushrooms, but they will cook down considerably. Increase the heat slightly to medium-high. Resist the urge to stir too frequently at this stage. Allow the mushrooms to cook undisturbed for about 3-4 minutes. This allows them to release theirgin extractisture and begin to brown properly, which is key to developing that deep, rich flavor.
Once the mushrooms have started to brown, add the chopped garlic and chopped fresh thyme to the skillet. Stir everything together and continue to cook for another 1-2 minutes until the garlic is fragrant. Be careful not to burn the garlic, as this can impart a bitter taste. The thyme will release its lovely herbaceous aroma, complementing the earthy mushrooms and sweet onions beautifully.
Pour in the 1/4 cup of white grape juice or broth. This liquid will help deglaze the pan, picking up all those delicious browned bits stuck to the bottom, and will also contribute moisture to help the onions and mushrooms tenderize further. Scrape the bottom of the skillet with your spatula to incorporate these flavorful bits. Let the liquid simmer and reduce for about 3-5 minutes, until it’s mostly evaporated and the mushrooms and onions are tender and appear nicely caramelized.
Stir in the chopped fresh parsley and the optional truffle oil. The parsley adds a burst of freshness and a vibrant green color, while the truffle oil (if you’re using it) will impart an incredibly luxurious, earthy aroma and flavor. Give everything a good stir to combine. Remove the caramelized mushroom mixture from the skillet and set it aside in a bowl. Wipe the skillet clean with a paper towel; you’ll need it for grilling the sandwiches.

Assembling and Grilling the Sandwiches

Grilling to Golden Perfection

In a small bowl, combine the shredded fontina cheese and the grated Parmigiano Reggiano. Mix these cheeses together thoroughly. The fontina will provide excellent meltiness and a slightly nutty flavor, while the Parmigiano Reggiano will add a sharp, salty depth that complements the sweet caramelized mushrooms.
Lay out your four slices of bread on a clean surface. Generously spread half of the cheese mixture evenly over two of the bread slices. This will form the bottom layer of your grilled cheese, ensuring a gooey cheese pull with every bite.
Spoon a good portion of your prepared caramelized mushroom and onion mixture evenly over the cheese on the two bread slices. Don’t be shy; you want plenty of that delicious filling in every sandwich.
Top the mushroom mixture with the remaining cheese mixture, spreading it evenly. Then, place the other two slices of bread on top to complete your sandwiches.
Now, it’s time to grill! Spread the room-temperature salted butter evenly onto one side of each assembled sandwich. This butter will create that irresistible golden-brown crust.
Place the two buttered sandwiches into the clean skillet you used earlier, butter-side down, over medium-low heat. Cook for 4-5 minutes, or until the bottom slice of bread is golden brown and toasted. Carefully flip the sandwiches using a spatula.
Cook the other side for another 4-5 minutes, or until it’s also golden brown and the cheese inside is completely melted and gooey. You may need to adjust the heat slightly to prevent burning while ensuring the cheese melts thoroughly. If the bread is browning too quickly, you can cover the skillet for a minute or two to help the cheese melt through.
Once both sides are beautifully golden and the cheese is oozing out, carefully remove the Caramelized Mushroom Grilled Cheese sandwiches from the skillet. Let them rest for just a minute before slicing them in half diagonally. This brief rest allows the cheese to set slightly, making them easier to handle.
