Mushroom Ricotta Open-Faced Sandwich Ingredients
For the Mushroom Sauté
• Nonstick Cooking Spray – Prevents sticking on the baking sheet for easy cleanup.
• Extra Virgin Olive Oil – Adds richness and aids in sautéing; any mild cooking oil works as a substitute.
• Onion (1 large, diced) – Caramelizes beautifully to add flavor and sweetness to the dish.
• Mushrooms (24 oz, sliced) – The star ingredient, bringing an earthy flavor and meaty texture; opt for cremini or button mushrooms.
• Garlic (2 cloves, minced) – Enhances aroma and taste; fresh garlic is ideal, but powdered can substitute in a pinch.
For the Ricotta Spread
• Ricotta (1 container, 15 oz) – Provides a creamy texture for spreading on the bread; cottage cheese can be used for a lower-fat option.
• Chives (2 tbsp, minced, divided) – Adds a mild onion flavor and a pop of color; substitute with green onions or shallots if needed.
For Assembling
• Rustic-Style Bread (4 slices, thick-cut) – Serves as the hearty base; feel free to use whole grain or gluten-free bread instead.
• Gruyere Cheese (1 cup, shredded) – Contributes melty richness and nutty undertones; mozzarella can be a milder substitute.
• Kosher Salt & Pepper – Essentials for seasoning to taste and enhancing the overall flavor of your Mushroom Ricotta Open-Faced Sandwich.
Step‑by‑Step Instructions for Mushroom Ricotta Open-Faced Sandwich
Step 1: Preheat and Prepare
Begin by preheating your oven to 425°F (220°C). While the oven heats, prepare a baking sheet by lightly spraying it with nonstick cooking spray. This step will help prevent the sandwich from sticking and ensure a crispy finish. Set the baking sheet aside as you move on to the sautéing process.
Step 2: Sauté the Onions
In a large skillet, heat 2 tablespoons of extra virgin olive oil over medium-high heat. Toss in the diced onion and sauté for about 5 minutes, stirring occasionally, until they begin to turn golden brown and fragrant. This caramelization enhances the sweetness of the onion, setting a flavorful foundation for your Mushroom Ricotta Open-Faced Sandwich.
Step 3: Cook the Mushrooms
Add the sliced mushrooms to the skillet with the onions. Cook for 8 to 10 minutes, stirring frequently until the mushrooms are browned and most of their moisture has evaporated. You’ll notice the mushrooms taking on a rich color, which indicates they’ve cooked down beautifully, intensifying their earthy flavor.
Step 4: Add Garlic
Lower the heat to medium and mix in the minced garlic, cooking for an additional 30 seconds until fragrant. Be careful not to let the garlic burn, as it can turn bitter. This step is crucial for incorporating that delightful aroma and flavor into your Mushroom Ricotta Open-Faced Sandwich.
Step 5: Season and Set Aside
Once the garlic is fragrant, season the mushroom mixture with kosher salt and black pepper to taste. Remove the skillet from heat and set the mushroom mixture aside, allowing the flavors to meld while you prepare the ricotta spread, maintaining that cozy vibe of your open-faced sandwich.
Step 6: Prepare the Ricotta Spread
In a medium bowl, combine 15 ounces of ricotta cheese with 1 tablespoon of minced chives. Season the mixture with salt and pepper to taste, mixing until smooth. This creamy spread will be the bedrock of your Mushroom Ricotta Open-Faced Sandwich, adding richness alongside the sautéed mushrooms.
Step 7: Assemble the Sandwiches
Take your rustic-style bread and lightly brush one side of each slice with olive oil. Place the bread slices oil-side down on the prepared baking sheet. This will ensure they get perfectly crispy as they bake. Spread an even layer of the ricotta mixture over each slice, making sure to cover the surface well.
Step 8: Top with Mushroom Mixture
Next, generously spoon the sautéed mushroom mixture on top of each ricotta-covered bread slice. Make sure to evenly distribute the mushrooms so each bite of your Mushroom Ricotta Open-Faced Sandwich is full of flavor. Finish by sprinkling 1 cup of shredded Gruyere cheese over the top of each sandwich.
Step 9: Bake Until Golden
Place the baking sheet in the preheated oven and bake for about 15 minutes, or until the toppings are hot and the bread’s underside is golden brown. Keep an eye on the sandwiches, as they should be bubbling and deliciously enticing when ready to serve.
Step 10: Garnish and Serve
Once baked, remove the sandwiches from the oven and sprinkle the remaining 1 tablespoon of minced chives over the top for a fresh finish. Serve your Mushroom Ricotta Open-Faced Sandwiches immediately, reveling in the delightful combination of textures and flavors that make this dish comforting and satisfying.

Make Ahead Options
These Mushroom Ricotta Open-Faced Sandwiches are perfect for busy weeknights or meal prepping! You can prepare the sautéed mushroom mixture and ricotta spread up to 3 days in advance. Simply store the mushroom mixture and ricotta spread separately in airtight containers in the refrigerator to maintain their texture and flavor. When you’re ready to enjoy, brush the bread with olive oil, spread the ricotta, top with the mushroom mixture, sprinkle with Gruyere cheese, and bake at 425°F (220°C) for about 15 minutes until golden. This way, you’ll have a comforting, restaurant-quality meal ready with minimal effort, just as delicious as when freshly made!
