this Recipe

Ingredients:

• For the Caramelized Onions:
• 2 large yellow onions, thinly sliced
• 2 tablespoons olive oil
• 1 tablespoon butter
• 1 teaspoon brown sugar
• 1/2 teaspoon balsamic vinegar
• Salt and freshly ground black pepper to taste
• For the Sautéed Mushrooms:
• 1 pound cremini mushrooms, sliced
• 2 tablespoons olive oil
• 2 cloves garlic, minced
• 1/4 cup dry white wine (optional, but recommended)
• 1 tablespoon fresh thyme leaves
• Salt and freshly ground black pepper to taste
• For the Sandwich Assembly:
• 4 slices sourdough bread (or your favorite bread)
• 4 ounces Swiss cheese, thinly sliced
• 2 tablespoons butter, softened
• 1 tablespoon Dijon mustard (optional)

Caramelizing the Onions:

Okay, let’s start with the heart of this sandwich – the caramelized onions. Trust me, this step is worth the effort. The sweetness and depth of flavor they add are incredible.

1. Prep the Onions: First, peel and thinly slice your two large yellow onions. I prefer slicing them pole to pole (from root to tip) for even cooking. Don’t worry if you cry a little; it’s a sign you’re doing it right!
2. Heat the Oil and Butter: In a large skillet (cast iron is great if you have one), heat the olive oil and butter over medium-low heat. The butter adds richness, and the olive oil prevents it from burning.
3. Add the Onions: Add the sliced onions to the skillet and stir to coat them with the oil and butter.
4. The Long, Slow Cook: This is where the patience comes in. Cook the onions over very low heat, stirring occasionally, for about 30-45 minutes, or until they are a deep golden brown and very soft. The key is low and slow. If the onions start to brown too quickly, reduce the heat even further. We want them to caramelize, not burn.
5. Add Sugar and Balsamic: Once the onions are nicely caramelized, stir in the brown sugar and balsamic vinegar. The brown sugar helps enhance the sweetness, and the balsamic adds a touch of tanginess. Cook for another 2-3 minutes, stirring constantly, until the sugar is dissolved and the balsamic is absorbed.
6. Season: Season the caramelized onions with salt and freshly ground black pepper to taste. Give them one last stir, then remove them from the skillet and set aside.

Sautéing the Mushrooms:

Next up, let’s get those earthy, savory mushrooms ready. This part is much quicker than the onions, but equally important for a fantastic sandwich.

1. Prep the Mushrooms: Clean your cremini mushrooms (also known as baby bellas) and slice them. I usually just wipe them clean with a damp paper towel to avoid them getting waterlogged.
2. Heat the Oil: In the same skillet you used for the onions (no need to wash it!), heat the olive oil over medium-high heat.
3. Sauté the Mushrooms: Add the sliced mushrooms to the skillet and cook, stirring occasionally, until they are browned and softened. This should take about 8-10 minutes. Don’t overcrowd the pan, or the mushrooms will steam instead of brown. If you need to, cook them in batches.
4. Add Garlic and Thyme: Once the mushrooms are browned, add the minced garlic and fresh thyme leaves. Cook for another minute, stirring constantly, until the garlic is fragrant. Be careful not to burn the garlic.
5. Deglaze with Wine (Optional): If you’re using white wine, now’s the time to add it. Pour the wine into the skillet and scrape up any browned bits from the bottom of the pan. This adds a ton of flavor! Let the wine reduce for a minute or two until it’s almost completely evaporated.
6. Season: Season the sautéed mushrooms with salt and freshly ground black pepper to taste. Give them a final stir, then remove them from the skillet and set aside.

Assembling the Swiss Mushroom Melt:

Alright, we’ve got our caramelized onions and sautéed mushrooms ready. Now comes the fun part – putting it all together to create the ultimate Swiss Mushroom Melt!

1. Prepare the Bread: Lightly butter one side of each slice of sourdough bread. This will help them get nice and golden brown in the pan.
2. Optional Dijon: If you like a little tang, spread a thin layer of Dijon mustard on the unbuttered side of two slices of bread. This is totally optional, but I think it adds a nice touch.
3. Layer the Cheese: Place the bread slices (buttered side down) in a clean skillet over medium-low heat. On each slice of bread, layer half of the Swiss cheese.
4. Add the Toppings: On top of the cheese on one slice of bread, pile half of the caramelized onions and half of the sautéed mushrooms. Repeat with the other slice of bread.
5. Melt and Combine: Cook the sandwiches until the cheese is melted and gooey, and the bread is golden brown and toasted. This should take about 3-5 minutes per side. You can cover the skillet with a lid to help the cheese melt faster.
6. Combine and Serve: Once the cheese is melted and the bread is toasted, carefully remove the sandwiches from the skillet. Place one slice of bread on top of the other to create a complete sandwich. Cut in half and serve immediately.

Tips for the Perfect Swiss Mushroom Melt:

• Use Quality Ingredients: The better the ingredients, the better the sandwich. Use good quality sourdough bread, fresh mushrooms, and real Swiss cheese.
• Don’t Rush the Onions: Caramelizing onions takes time, so be patient. The low and slow cooking process is what brings out their sweetness and depth of flavor.
• Adjust Seasoning to Taste: Season the onions and mushrooms generously with salt and pepper. Taste as you go and adjust the seasoning to your liking.
• Get Creative with Cheese: While Swiss cheese is classic for this sandwich, you can experiment with other cheeses like Gruyere, provolone, or even a sharp cheddar.
• Add a Sauce: For an extra layer of flavor, consider adding a sauce like garlic aioli, pesto, or a balsamic glaze.

Variations:

• Vegetarian Option: This recipe is already vegetarian-friendly!
• Vegan Option: Use vegan butter, vegan cheese, and omit the white wine or use a vegan-friendly substitute.
• Add Protein: Add grilled chicken, steak, or tofu for a heartier sandwich.
• Spice it Up: Add a pinch of red pepper flakes to the mushrooms for a little heat.

Enjoy your delicious homemade Swiss Mushroom Melt! I hope you love it as much as I do.
