Welcome to your new favorite sandwich! The Gourmet Mushroom & Brie Sandwich is a delightful blend of earthy mushrooms, creamy Brie, and crisp arugula, all nestled between perfectly toasted sourdough bread. It's an easy, yet gourmet, choice for lunch or a light dinner.
Portobello mushrooms bring a meaty texture and rich flavor that holds its own in this sandwich. Brie cheese adds a creamy, tangy component that melts beautifully. Sourdough bread provides a sturdy, flavorful base that crisps up nicely when grilled. Olive oil is used for sautéing, adding a smooth richness to the mushrooms. Balsamic vinegar adds a hint of sweetness and acidity, elevating the mushroom flavor. Garlic enhances the aroma and adds depth. Butter ensures the bread grills to a perfect golden brown. Lastly, a handful of arugula offers a peppery freshness that balances the richness of the cheese and mushrooms.
This sandwich pairs beautifully with a simple mixed green salad tossed with a light vinaigrette. A side of roasted sweet potato wedges or a cup of tomato bisque soup also complements this gourmet delight wonderfully.
Start by slicing your portobello mushrooms into even pieces so they cook uniformly. Heat up the olive oil in a skillet over medium heat, then toss in the minced garlic. The moment you smell that garlic aroma, it's time to add the mushrooms. Season them with a bit of salt and pepper, and let them cook, stirring occasionally, until they're tender, which usually takes about five minutes.
Once the mushrooms are soft, stir in the balsamic vinegar. Let it bubble away for a couple of minutes until it's reduced a bit and the mushrooms have absorbed that sweet and tangy goodness. Then, take the skillet off the heat.
Now for the bread: spread butter generously on one side of each slice. On the unbuttered side of two slices, layer the Brie cheese, followed by the cooked mushrooms, and top with a handful of fresh arugula. Place the remaining bread slices on top, buttered side facing out.
Heat a clean skillet over medium heat. Place your sandwiches into the skillet. Grill them until the bread is golden brown and the Brie is melting, about 3-4 minutes on each side. Keep an eye on them to prevent burning, and press gently with a spatula for even browning. Once they’re done, slice them in half and serve warm.
