Ingredients
Scale
Mushroom Sauté
- 2 cups mushrooms, sliced (button or cremini mushrooms work well)
- 1 medium onion, thinly sliced
- 2 tablespoons butter (for sautéing)
- 1 tablespoon olive oil
- 2 cloves garlic, minced
- 1/2 teaspoon thyme (optional)
- Salt and pepper, to taste
Sandwich Assembly
- 4 slices sourdough or any hearty bread
- 4 slices of cheese (Swiss, cheddar, or mozzarella)
- 2 tablespoons butter (for grilling)
Instructions
- Sauté the Mushrooms: In a large skillet, heat 2 tablespoons of butter and 1 tablespoon of olive oil over medium heat until melted and shimmering.
- Cook Mushrooms and Onions: Add the sliced mushrooms and onions to the skillet, sautéing them until the mushrooms release their moisture and become golden brown, approximately 7-10 minutes.
- Add Garlic and Thyme: Stir in the minced garlic and optional thyme, cooking for another 1-2 minutes until fragrant and well combined.
- Season the Mixture: Season the sautéed mushroom mixture with salt and pepper to taste, then remove the skillet from heat and set aside.
- Prepare the Bread: Lay out the slices of bread on a clean surface to assemble the sandwiches.
- Assemble Sandwiches: Evenly spoon the mushroom and onion mixture onto two slices of bread, spreading it out to cover each slice.
- Add Cheese: Place a slice of your chosen cheese on top of the mushroom mixture on each bread slice.
- Complete the Sandwich: Top each with the remaining bread slices to close the sandwiches.
- Heat Skillet: Warm a nonstick skillet or griddle over medium-low heat for grilling the sandwiches.
- Butter the Sandwiches: Spread 1-2 tablespoons of butter on the outside of each sandwich to ensure a crisp, golden crust when grilled.
- Grill the Sandwiches: Place sandwiches in the skillet and cook for 3-4 minutes per side, or until the bread turns golden brown and the cheese melts thoroughly.
- Serve: Remove the sandwiches from the skillet, cut each in half, and serve immediately while warm and gooey.
Notes
- Use button or cremini mushrooms for the best texture and flavor.
- Adjust the amount of butter for grilling depending on your preference for crust crispiness.
- Thyme is optional but adds a lovely herbaceous note to the filling.
- Swiss cheese provides a nutty flavor, cheddar adds sharpness, and mozzarella melts wonderfully for creaminess—choose based on your taste.
- Serve with a side salad or your favorite chips for a complete meal.
- To make it vegetarian, ensure the bread and cheese are vegetarian-friendly (no animal rennet).
