Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

2 tbsp butter (plus extra for bread)
1 tbsp olive oil
1 shallot, finely chopped
2 cups mushrooms (Portobello, Cremini, or Shiitake), sliced
1 tsp thyme (fresh or dried)
1 tbsp balsamic vinegar (optional)
Salt and pepper, to taste
4 slices Swiss cheese (or Gruyère for richer flavor)
8 slices bread (rye, sourdough, or artisan)

Directions

Heat butter and olive oil in a skillet over medium heat. Add shallot and cook until softened.
Add mushrooms, thyme, salt, and pepper. Sauté until mushrooms are browned and tender, about 6–8 minutes. Stir in balsamic vinegar if using, then remove from heat.
Butter one side of each bread slice. On the unbuttered side, layer cheese, mushroom mixture, and more cheese. Top with another slice of bread, buttered side out.
Heat a skillet or panini press. Cook sandwiches for 2–3 minutes per side, pressing gently, until bread is golden brown and cheese is melted.
Slice and serve hot.

Variations

Add caramelized onions for extra sweetness.
Use fontina, provolone, or cheddar instead of Swiss cheese.
Spread Dijon mustard or garlic aioli on the bread before assembling.
Add fresh spinach or arugula for a peppery bite.
Make it heartier with slices of roast beef or turkey.

Storage/reheating

Best enjoyed fresh, as the bread can lose crispness.
If needed, store cooled sandwiches in the fridge for up to 1 day.
Reheat in a skillet over low heat or in an oven at 350°F until warmed through and crispy.
Not suitable for freezing, as the texture of mushrooms and bread may suffer.
