Save Rainy afternoons were made for sandwiches like this. I discovered the magic of adding cream to sautéed mushrooms completely by accident when I had some leftover from another recipe and my grilled cheese has never been the same since.
My roommate walked in while I was making these once and demanded to know what smelled so incredible. We ended up sitting on the kitchen floor eating them straight from the pan, burning our fingers because we could not wait another second.
Ingredients
- Mushrooms: Cremini or button mushrooms work beautifully here. Slice them thin so they cook evenly and get those gorgeous golden edges
- Unsalted butter: One tablespoon for the mushrooms and two softened for the bread. Butter gives the best flavor and that perfect golden crunch
- Garlic clove: Minced fine so it distributes through the mushrooms without any harsh bits
- Fresh thyme: Earthy and aromatic. Dried works in a pinch but fresh thyme makes the mushrooms sing
- Heavy cream: The secret ingredient that turns sautéed mushrooms into something luxurious and spreadable
- Sourdough bread: Sturdy enough to hold the filling and gets wonderfully crisp. Country bread is a great alternative
- Swiss or Gruyère cheese: Both melt beautifully and have a nutty flavor that pairs perfectly with mushrooms
- Salt and black pepper: Taste and adjust. Mushrooms need a good amount of salt to really shine
Instructions
- Sauté the mushrooms:
- Melt one tablespoon butter in a skillet over medium heat. Add the sliced mushrooms and cook stirring often until they are golden brown and have released all their moisture about 6 to 8 minutes. Watch them transform from watery to concentrated and umami rich.
- Add the aromatics:
- Stir in the minced garlic and thyme. Cook for just one minute until fragrant. Season generously with salt and pepper.
- Create the creamy filling:
- Reduce the heat to low. Pour in the heavy cream and stir constantly for 1 to 2 minutes. The mushrooms should become coated and creamy but not soupy. Remove from heat and set aside to cool slightly.
- Assemble the sandwiches:
- Lay out all four bread slices. Place a slice of cheese on two pieces. Divide the mushroom mixture between them. Top with the remaining cheese slices and the other bread pieces.
- Butter the bread:
- Spread the softened butter generously on the outside of each sandwich. This ensures even golden browning and that irresistible crunch.
- Grill to perfection:
- Heat a clean skillet over medium low heat. Place the sandwiches in the pan and cook for 3 to 4 minutes per side. Press gently with a spatula and flip when the bread is deep golden and the cheese is melty.
- Serve hot:
- Remove from the skillet and slice each sandwich in half. Serve immediately while the cheese is still molten and the bread is at its crispest.
Save This sandwich has become my go to when I need food that feels like a hug. Something about the combination of warm bread earthy mushrooms and creamy cheese just makes everything better.
Choosing Your Mushrooms
Cremini mushrooms are my first choice because they have a slightly deeper flavor than white button mushrooms. Slice them about a quarter inch thick so they cook through but still maintain some texture. Do not be afraid to let them get really brown in the pan.
The Bread Matters
Sourdough is ideal because its sturdy structure stands up to the hearty mushroom filling and its tangy flavor complements the creaminess. Let your bread sit out for an hour before using if it is very fresh. Slightly stale bread actually grills better.
Make It Your Own
Once you master the basic technique this sandwich is incredibly forgiving. A handful of fresh baby spinach adds color and nutrition. A smear of Dijon mustard on the bread cuts through the richness. Different cheeses bring completely different personalities.
- Add caramelized onions for extra sweetness and depth
- Try fontina or Taleggio for an even meltier experience
- A pinch of red pepper flakes in the mushrooms adds gentle warmth
Save Make these on a day when you need comfort. They are simple special and guaranteed to make your kitchen smell amazing.
