Mushroom Swiss Grilled Cheese (Printable)

Savory grilled cheese featuring sautéed mushrooms and melted Swiss cheese between crispy rye bread slices.

# Ingredient List:

→ Vegetables

01 - 1 cup cremini or white button mushrooms, cleaned and sliced
02 - 1 small shallot, finely chopped
03 - 1 clove garlic, minced

→ Dairy

04 - 4 slices Swiss cheese
05 - 2 tablespoons unsalted butter, softened, plus extra for sautéing

→ Bread

06 - 4 slices rye bread

→ Seasonings

07 - 1 tablespoon olive oil
08 - Salt and black pepper to taste
09 - 1 teaspoon fresh thyme leaves, optional

# Directions:

01 - Heat olive oil and 1 tablespoon butter in a skillet over medium heat. Add shallot and sauté for 1 minute until softened.
02 - Add mushrooms and cook, stirring occasionally, for 5 to 7 minutes until golden and any released liquid has evaporated. Stir in garlic and thyme, cook for 1 minute. Season with salt and black pepper to taste. Transfer to a plate and set aside.
03 - Lay out rye bread slices. Place one slice of Swiss cheese on two bread slices. Distribute mushroom mixture evenly over the cheese, then top with another slice of Swiss cheese. Cover each with a remaining bread slice.
04 - Generously butter the outside surfaces of each assembled sandwich.
05 - Wipe out the skillet and return to medium-low heat. Place sandwiches in the skillet and cook 3 to 4 minutes per side until bread is golden brown and cheese is fully melted, gently pressing with a spatula as needed.
06 - Cut sandwiches diagonally and serve warm.

# Expert Advice:

01 -
  • It transforms simple ingredients into something that feels fancy without any extra effort.
  • The earthy mushrooms and nutty Swiss create a flavor combination that's deeply satisfying and never boring.
  • It comes together in under half an hour, perfect for lunch or a quick dinner.
  • The crispy rye bread adds a slight tang that balances the richness of the cheese beautifully.
02 -
  • Don't rush the mushrooms, if you stir them too often they'll steam instead of browning, and you'll miss out on all that deep, caramelized flavor.
  • Use medium-low heat when grilling the sandwiches so the bread doesn't burn before the cheese has a chance to melt properly.
  • Softened butter spreads much easier than cold butter and gives you a more even, golden crust.
03 -
  • Let the mushrooms cool slightly before assembling so they don't make the bread soggy or melt the cheese unevenly.
  • Press the sandwich gently with a spatula while grilling to help the cheese melt faster and create better contact with the pan for even browning.
  • If you're making more than two sandwiches, keep the finished ones warm in a low oven while you cook the rest.
