# The Ingredients You'll Need:
→ Mushrooms
01 - 7 oz cremini or button mushrooms, cleaned and sliced
02 - 1 tablespoon unsalted butter
03 - 1 small garlic clove, minced
04 - 1 tablespoon fresh thyme leaves or ½ teaspoon dried thyme
05 - Salt and black pepper, to taste
06 - 2 tablespoons heavy cream
→ Sandwich
07 - 4 slices sourdough or country bread
08 - 4 slices Swiss or Gruyère cheese (3 oz)
09 - 2 tablespoons unsalted butter, softened
# Step-by-Step Instructions:
01 - Melt 1 tablespoon butter in a skillet over medium heat. Add mushrooms and cook, stirring frequently, until golden brown and moisture evaporates, about 6 to 8 minutes.
02 - Stir in minced garlic and thyme; cook 1 minute until aromatic. Season with salt and pepper.
03 - Lower heat to low. Add heavy cream and cook for 1 to 2 minutes until mushrooms are creamy yet not liquid. Remove from heat.
04 - Place cheese slices on two bread slices. Evenly distribute mushroom mixture over cheese, then top each with another cheese slice. Cover with remaining bread slices.
05 - Spread softened butter evenly on the outside of each sandwich.
06 - Heat a clean skillet or griddle over medium-low heat. Cook each sandwich 3 to 4 minutes per side, pressing gently, until bread is golden brown and cheese has melted.
07 - Remove sandwiches, cut in half, and serve immediately while hot.
