# What You'll Need:

→ Vegetables

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

07 - 1 tablespoon olive oil
08 - Salt and black pepper to taste

# How To Make:

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, for 5 to 7 minutes until golden and any liquid has evaporated. Stir in garlic and thyme; cook for 1 minute. Season with salt and black pepper. Remove from heat and set aside.
03 - Lay out rye bread slices. Place a slice of Swiss cheese on two of the bread slices. Spoon the mushroom mixture evenly over the cheese, then top with another slice of Swiss cheese. Cover with the remaining bread slices.
04 - Butter the outsides of each sandwich evenly.
05 - Wipe out the skillet and return to medium-low heat. Add sandwiches and cook 3 to 4 minutes per side until bread is golden and cheese is melted, pressing gently with a spatula as needed.
06 - Slice and serve warm.

# Expert Advice:

01 -
  • The earthy mushrooms add a satisfying meatiness that makes this feel like a real meal, not just a snack.
  • Rye bread brings a slight tang that balances the richness of melted Swiss cheese beautifully.
  • It comes together in under half an hour, making it perfect for lunch or a lazy dinner.
  • You can customize it easily with whatever herbs or cheese you have on hand.
02 -
  • If your heat is too high, the bread will burn before the cheese melts, so keep it at medium-low and be patient.
  • Don't skip cooking the mushrooms long enough, they need time to lose their moisture or your sandwich will be soggy.
  • Softened butter spreads much more evenly than cold butter, which can tear the bread.
03 -
  • Press down gently with your spatula while grilling to help the layers meld together without squishing out the filling.
  • If you're making multiple sandwiches, keep the finished ones warm in a low oven while you cook the rest.
  • A cast iron skillet holds heat beautifully and creates an even, crispy crust.
