Gourmet Garlic Mushroom Grilled Cheese (Print version)

A crisp sourdough grilled cheese packed with garlic butter mushrooms, Gruyere, fontina, and herbs.

# Ingredients:

For the garlic mushrooms

01 - 8 oz (225 g) cremini mushrooms, sliced
02 - 1 tablespoon olive oil
03 - 1 tablespoon unsalted butter
04 - 2 large garlic cloves, minced
05 - 1 teaspoon fresh thyme leaves, or 1/4 teaspoon dried thyme
06 - 1/4 teaspoon fine salt, plus more to taste
07 - 1/8 teaspoon black pepper
08 - 1 teaspoon fresh lemon juice

For the sandwiches

09 - 4 slices sourdough bread
10 - 2 teaspoons Dijon mustard
11 - 3 oz (85 g) Gruyere cheese, shredded
12 - 3 oz (85 g) fontina cheese, shredded
13 - 2 tablespoons unsalted butter, softened, for the bread

# Instructions:

01 - Heat the olive oil and 1 tablespoon butter in a large skillet over medium-high heat. Add the mushrooms and cook for 8-10 minutes, stirring now and then, until their liquid evaporates and the slices are browned.
02 - Stir in the garlic, thyme, salt, and pepper. Cook for 1 minute until fragrant, then stir in the lemon juice. Transfer the mushrooms to a plate and wipe out the skillet.
03 - Butter one side of each sourdough slice. Flip 2 slices over and spread the unbuttered sides with Dijon mustard.
04 - Divide half the Gruyere and fontina over the Dijon sides. Add the mushrooms, then top with the remaining cheese. Close with the remaining bread, buttered sides facing out.
05 - Set the sandwiches in the skillet over medium-low heat. Cook for 3-4 minutes per side, pressing gently, until the bread is golden and crisp and the cheese is melted.
06 - Rest the sandwiches for 1 minute, then slice and serve while the cheese is still warm and stretchy.

# Good to know:

01 - Cook the mushrooms until dry and browned before adding garlic.
02 - Medium-low heat helps the cheese melt before the bread over-browns.
03 - Best served hot from the skillet.
