Scale

  • 1 large onion, diced
  • 24 ounces mushrooms, sliced
  • 2 cloves garlic, minced
  • 2 tablespoons minced chives (divided)

Dairy

  • 1 (15-ounce) container ricotta cheese
  • 1 cup shredded Gruyere cheese

Pantry Items

  • 1 tablespoon extra virgin olive oil
  • Olive oil for brushing bread
  • Nonstick cooking spray
  • Kosher salt, to taste
  • Freshly ground black pepper, to taste

Bakery

  • 4 slices rustic-style bread, sliced thick

Instructions

  1. Preheat Oven and Prepare Baking Sheet: Preheat your oven to 425°F (220°C) and spray a baking sheet with nonstick cooking spray to prevent sticking.
  2. Sauté Onions: Heat 1 tablespoon of olive oil in a large skillet over medium-high heat. Add the diced onion and sauté, stirring frequently, until the onions are browned and caramelized, enhancing their sweetness.
  3. Cook Mushrooms: Add the sliced mushrooms to the skillet with the onions. Cook, stirring often, until the mushrooms are mostly browned and their moisture has evaporated to develop rich flavor.
  4. Cool Down and Add Garlic: Reduce the heat to medium and let the pan cool slightly for a couple of minutes to avoid burning the garlic.
  5. Add Garlic and Season: Stir in the minced garlic and cook for 30 seconds to 1 minute until fragrant, stirring constantly. Remove the mushroom mixture from heat and season generously with kosher salt and freshly ground black pepper. Set aside.
  6. Prepare Ricotta Mixture: In a bowl, combine the ricotta cheese with 1 tablespoon of minced chives. Season with salt and pepper to taste and mix well.
  7. Prepare Bread: Lightly brush one side of each bread slice with olive oil. Place the slices oil side down on the prepared baking sheet to create a crispy base.
  8. Assemble Sandwiches: Spread a generous layer of the ricotta mixture over each slice of bread, then top evenly with the sautéed mushroom and onion mixture. Sprinkle each sandwich with shredded Gruyere cheese for a creamy, melty finish.
  9. Bake: Bake the sandwiches in the preheated oven for about 15 minutes, or until the toppings are hot and bubbly and the bottom of the bread is browned and crisp.
  10. Garnish and Serve: Remove the sandwiches from the oven and sprinkle with the remaining 1 tablespoon of minced chives for a fresh pop of color and flavor. Serve immediately and enjoy your warm, flavorful open-faced sandwiches!

Notes

  • You can use cremini, white button, or portobello mushrooms based on your preference; mixing varieties adds depth of flavor.
  • For extra richness, consider adding a drizzle of truffle oil before serving.
  • Your bread choice affects texture—rustic sourdough or country-style bread works best for crispness and heartiness.
  • These sandwiches are best enjoyed fresh but can be reheated briefly in the oven to restore crispness.
  • Feel free to customize with additional herbs like thyme or rosemary for added aroma.
