Save The way our tiny apartment filled with the smell of butter and mushrooms that rainy Tuesday is something I still think about. My roommate had bought way too many mushrooms from the market and we were both too broke to let them go to waste. We stood in the kitchen watching the rain against the window while the mushrooms sputtered in the pan. That impromptu experiment turned into the sandwich I've been making ever since.
I made these for my sister when she was going through a breakup and needed serious comfort food. She took one bite and actually stopped talking for a full minute which never happens. The way the cheese stretches when you pull the sandwich apart is the kind of small joy that fixes bad days.
Ingredients
- 200 g cremini or button mushrooms: These develop the best nutty flavor when sautéed until golden and give you that meaty texture that makes the sandwich feel substantial
- 1 tablespoon unsalted butter: Use real butter here because it creates that rich nutty base that olive oil just cannot replicate for mushrooms
- 1 small garlic clove: One fresh clove is plenty since you want just a subtle warmth behind the earthy mushrooms
- 1 tablespoon fresh thyme leaves: Fresh thyme adds this woodsy aromatic quality that pairs perfectly with mushrooms though dried works in a pinch
- Salt and black pepper: Mushrooms need proper seasoning to wake up their natural flavors so do not be shy with the pepper
- 2 tablespoons heavy cream: This is the secret ingredient that makes the mushrooms feel indulgent and helps them cling to the cheese
- 4 slices sourdough or country bread: Something sturdy that will not get soggy and develops incredible crunch when buttered and griddled
- 4 slices Swiss or Gruyère cheese: Both melt beautifully with Swiss being milder and Gruyère adding more nutty depth
- 2 tablespoons unsalted butter: Softened butter spreads evenly and creates that gorgeous golden crust we are all after
Instructions
- Sauté the mushrooms until golden:
- Melt 1 tablespoon butter in a skillet over medium heat and add the sliced mushrooms cooking them until they release their moisture and turn deep golden brown which takes about 6 to 8 minutes
- Add aromatics:
- Stir in the minced garlic and thyme cooking for just 1 minute until fragrant then season generously with salt and pepper
- Make them creamy:
- Reduce heat to low and stir in the heavy cream letting it bubble gently for 1 to 2 minutes until the mushrooms are coated in a velvety sauce that is not too runny
- Build your sandwiches:
- Layer cheese on two bread slices then spread the creamy mushrooms on top add another slice of cheese and close with the remaining bread
- Butter the exterior:
- Spread the softened butter evenly on the outside of each sandwich which is what creates that perfect golden crunch
- Grill to perfection:
- Cook the sandwiches in a clean skillet over medium low heat for 3 to 4 minutes per side pressing gently until the bread is deeply golden and the cheese is completely melted
- Service:
- Let them rest for just 30 seconds before slicing diagonally and serving while still hot and gooey
Save These have become my go to when friends cancel plans and I need something to look forward to instead. There is something meditative about standing at the stove listening to the gentle sizzle while the cheese melts into the mushrooms.
Bread Choices That Work Best
Sourdough is ideal because its tangy flavor cuts through the richness of the cheese and cream. Country bread or a hearty white bread works too but avoid anything too soft or the sandwich might fall apart. The key is finding something with structure that can hold up to all that creamy filling.
Cheese Swaps I Love
While Swiss and Gruyère are classic combos for mushrooms do not be afraid to experiment. A sharp cheddar adds bold flavor that stands up to the earthy mushrooms. Provolone melts incredibly well and adds a mild smokiness that works beautifully here.
Make It Your Own
Sautéed onions add sweetness that balances the savory mushrooms perfectly. A handful of fresh spinach wilts nicely into the creamy mixture and makes you feel slightly virtuous about eating grilled cheese for dinner. Try truffle oil in the mushrooms for a restaurant style upgrade.
- Add a pinch of red pepper flakes if you want subtle warmth
- A dab of Dijon on the bread before assembling adds bright contrast
- Let the assembled sandwiches rest for 5 minutes before cooking for better melt
