Ingredients
Scale
- 1 package (12-count) savory slider rolls
- 1 lb (454 g) mixed mushrooms, sliced
- 1 cup Gruyère, grated
- 1 cup Fontina, grated
- 3 tbsps Parmigiano Reggiano
- 4 tbsps (½ stick) unsalted butter, divided
- 2 tbsps unsalted butter, melted
- 1 tbsp olive oil
- 1 large shallot, thinly sliced
- 2 cloves garlic, minced
- 2–3 sprigs thyme, about 1 tsp, chopped
- ½ tsp kosher salt
- ¼ tsp kosher salt
- 1 tsp tamari (or Worcestershire if not vegetarian)
- ¼ tsp garlic powder
Instructions
- Preheat: Set the oven to 350°F (175°C), creating an ideal baking environment for these delectable vegetarian sliders.
- Sauté Mushrooms: In a large skillet over medium heat, melt olive oil and butter. Add sliced mushrooms and cook until golden-brown, stirring occasionally, about 5 minutes.
- Build Flavor Base: Introduce shallots, garlic, and thyme to the mushroom mixture, seasoning with salt and tamari. Allow the ingredients to meld and soften for 5-6 minutes, creating a rich aromatic foundation.
- Prepare Topping: Combine melted butter with Parmigiano Reggiano, garlic powder, and kosher salt in a small bowl, whisking to create a flavorful butter mixture.
- Assemble Sliders: Slice rolls horizontally and arrange bottom halves in a parchment-lined baking pan. Layer with half the cheese, then spread the caramelized mushroom mixture evenly. Top with remaining cheese and roll tops.
- Finish and Bake: Brush roll tops generously with the prepared butter mixture. Bake in the preheated oven for 12-15 minutes until rolls turn golden and cheese melts completely.
- Serve: Remove from oven, slice into individual sliders, and present while warm, inviting guests to savor these irresistible vegetarian delights.
Notes
- Mushroom Mastery: Select firm, fresh mushrooms like cremini or portobello for the most robust flavor and meaty texture.
- Flavor Amplification: Let the mushrooms caramelize slowly to develop deep, rich umami notes that elevate the entire slider experience.
- Cheese Selection Tip: Use freshly grated Parmigiano Reggiano for maximum melting quality and authentic taste compared to pre-shredded varieties.
- Serving Strategy: Enjoy these sliders immediately after baking to capture the perfect balance of crispy bread and melted, gooey cheese.
