Ingredients
  

4 slices of sourdough bread

1 cup Gouda cheese, shredded

1 cup mixed mushrooms (shiitake, cremini, and button), sliced

1 medium onion, thinly sliced

2 tablespoons unsalted butter

1 tablespoon olive oil

1 teaspoon garlic powder

Salt and pepper to taste

Fresh thyme sprigs (optional for garnish)

Instructions
 

Roast the Mushrooms and Onions:

    - Preheat your oven to 400°F (200°C).

      - In a mixing bowl, combine the sliced mushrooms and onions. Drizzle with olive oil and season with garlic powder, salt, and pepper. Toss to coat evenly.

        - Spread the mixture on a baking sheet and roast in the oven for 20-25 minutes, or until the mushrooms are golden and the onions are soft, stirring halfway through.

          Prepare the Bread:

            - While the mushrooms and onions are roasting, butter one side of each slice of sourdough bread with unsalted butter.

              Assemble the Sandwich:

                - On the non-buttered side of two slices of bread, layer half of the shredded Gouda cheese evenly.

                  - Add a generous portion of the roasted mushroom and onion mixture on top of the cheese, then sprinkle the remaining cheese on top to sandwich everything together.

                    - Place the unbuttered sides of the other two slices of bread on top to form two complete sandwiches.

                      Grill the Sandwiches:

                        - Heat a skillet or griddle over medium heat. Once hot, carefully place the sandwiches in the skillet.

                          - Grill the sandwiches for about 4-5 minutes on each side or until golden brown and the cheese is melted, pressing down gently with a spatula to help the cheese melt evenly.

                            Serve:

                              - Once grilled to perfection, remove the sandwiches from the skillet and allow them to rest for a minute.

                                - Cut each sandwich in half diagonally and serve immediately. Garnish with fresh thyme sprigs if desired.

                                    - Presentation Tips: Arrange the cut sandwiches on a rustic wooden board, serve with a small bowl of marinara or pesto for dipping, and sprinkle with extra thyme for a touch of elegance.
