Why This Roasted Mushroom Crostini Recipe is a Must-Try
It’s hard to pick a favorite component of this delightful appetizer. Is it the deeply savory, slightly crispy roasted shiitake mushrooms, infused with fragrant sliced garlic, fresh rosemary, and rich olive oil? Or is it the ethereal, creamy whipped ricotta mixture that forms the perfect bed for our star mushrooms? The truth is, it’s the harmonious combination of these elements that makes this crostini truly unforgettable.
Each bite delivers a satisfying crunch from the baguette, followed by the tender, umami-packed mushrooms, and then the cooling, luxurious sensation of the ricotta. The addition of a sweet and tangy balsamic glaze just before serving elevates the entire experience, tying all the flavors together in a truly remarkable way. This recipe isn’t just an appetizer; it’s a culinary journey in miniature, offering complex flavors with straightforward preparation.
The Secret to Perfectly Roasted Shiitake Mushrooms
Shiitake mushrooms are an excellent choice for this crostini due to their robust, earthy flavor and meaty texture. When roasted, they develop a wonderful depth of flavor and a slightly crispy edge that adds an irresistible element to the dish. The key to successful roasting lies in a few simple steps:
- Preparation: Remove the tough stems from the shiitake caps. Slice the caps into uniform ½-inch thick pieces to ensure even cooking.
- Seasoning: Toss the mushrooms generously with high-quality extra virgin olive oil, thinly sliced fresh garlic, and fresh rosemary sprigs. The garlic caramelizes slightly, and the rosemary infuses the mushrooms with its aromatic essence. Don’t forget a good pinch of kosher salt and freshly ground black pepper to enhance their natural flavors.
- High Heat Roasting: Roasting at a higher temperature (475°F or 250°C) allows the mushrooms to develop a beautiful golden-brown color and a desirable texture. Spreading them in a single layer on a large baking sheet is crucial to prevent steaming; this ensures they roast rather than just soften. Tossing them once or twice during cooking promotes even browning.
The result is a batch of intensely flavorful mushrooms, slightly charred and tender, ready to be the savory heart of your crostini.
How to Make Decadent Whipped Ricotta
Whipped ricotta is more than just a fancy term; it’s a game-changer for dishes like crostini. It transforms standard ricotta cheese into a silky-smooth, incredibly creamy, and utterly decadent spread. The process is remarkably simple:
Combine whole-fat ricotta cheese and a touch of extra virgin olive oil in a food processor. Process for just 15 to 20 seconds. This brief whipping introduces air into the cheese, breaks down any granular texture, and creates a remarkably light and airy consistency. After whipping, stir in a small amount of finely grated Parmigiano-Reggiano cheese for an extra layer of savory depth, and season generously with salt and pepper to taste.
In my opinion, whipping significantly improves the texture of ricotta straight out of the container. While homemade ricotta cheese or a high-quality, freshly made artisanal ricotta can be inherently smooth, they are often hard to come by. Whipping readily available store-bought ricotta ensures a luxurious mouthfeel that rivals the freshest options, making this appetizer accessible to everyone.
Assembling Your Gourmet Crostini
Once your mushrooms are roasted and your ricotta is whipped to perfection, the assembly is quick and fun. For the base, use a medium French baguette, sliced into ½-inch thick rounds and toasted until golden brown and crisp. This provides a sturdy yet delicate vessel for your toppings.
Each toasted baguette slice serves as the perfect foundation. Generously spread a spoonful of the whipped ricotta onto each crostini. The creamy white backdrop beautifully contrasts with the deep, rich colors of the roasted mushrooms. Next, artfully pile a spoonful of the warm (or lukewarm) roasted mushrooms on top of the ricotta. The textures play off each other – the crisp bread, the smooth ricotta, and the tender mushrooms.
Just before serving, a final flourish: garnish the crostini with a drizzle of balsamic glaze. While optional, this step is highly recommended. The glaze adds a wonderful sweet and tangy counterpoint that cuts through the richness of the ricotta and enhances the earthy notes of the mushrooms, truly completing the flavor profile. Serve immediately to enjoy the optimal contrast of textures.

Ingredients
Crostini:

- 1 lb (16 ounces) shiitake mushrooms stems removed, caps sliced ½-inch thick
- 2 tablespoons (30 mL) extra virgin olive oil
- 2-3 large garlic cloves thinly sliced
- 3 sprigs fresh rosemary (about 1 tablespoon leaves, roughly chopped)

Instructions
-
1. Prepare Crostini: Preheat your oven to 375°F (190°C) with a rack positioned in the center. Arrange the baguette slices evenly on a large baking sheet, ensuring they are not overlapping. Toast them for 10 to 15 minutes, or until they achieve a beautiful golden-brown color and are crispy. Remove from the oven and allow them to cool completely on a wire rack.
-
2. Roast Mushrooms: Increase the oven temperature to 475°F (250°C). Prepare the shiitake mushrooms by removing their tough stems and slicing the caps into ½-inch thick pieces. Spread the sliced mushrooms onto a clean half sheet pan in a single layer. Drizzle with 2 tablespoons of extra virgin olive oil, add the thinly sliced garlic, and scatter the rosemary sprigs (you can break them apart slightly with your hands to release more aroma). Season generously with kosher salt and freshly ground black pepper.
-
3. Cook Mushrooms: Roast the seasoned mushrooms for 12 to 18 minutes. For even cooking and browning, toss them gently once or twice with a wooden spoon during the roasting process. Once roasted, remove the pan from the oven and allow the mushrooms to cool on the pan on a rack until they are lukewarm. Discard the rosemary sprigs before assembling.
-
4. Prepare Whipped Ricotta: In the bowl of a small food processor, combine the ¾ cup whole fat ricotta cheese and 1 tablespoon of extra virgin olive oil. Process for 10 to 15 seconds until the mixture is completely smooth and airy. Transfer the whipped ricotta to a small bowl and stir in the 1 tablespoon of finely grated Parmigiano-Reggiano cheese. Season with kosher salt and freshly ground black pepper to taste, mixing well.
-
5. Assemble and Serve: To assemble, spread each toasted baguette slice with a generous layer of the whipped ricotta. Top each with a spoonful of the roasted mushrooms. If desired, drizzle with balsamic glaze just before serving. Serve your delicious Roasted Mushroom Crostini immediately to enjoy the best texture and flavor.
Tips and Variations for Your Crostini
While this recipe is fantastic as is, here are some ideas to customize it or ensure your success:
- Mushroom Alternatives: If shiitake mushrooms are not available, cremini (baby bella) mushrooms can be a good substitute. Oyster mushrooms would also work wonderfully for their delicate texture and earthy flavor.
- Herb Swaps: Not a fan of rosemary? Fresh thyme or a blend of Italian herbs could also complement the mushrooms beautifully. Add them during the roasting process.
- Cheese Enhancements: For a different flavor profile, consider adding a pinch of freshly grated nutmeg to the whipped ricotta, or even a tiny amount of lemon zest to brighten it up. A drizzle of truffle oil over the finished crostini would also add a luxurious touch.
- Spice It Up: A pinch of red pepper flakes tossed with the mushrooms before roasting will add a subtle kick if you enjoy a bit of heat.
- Make-Ahead Instructions: Both the roasted mushrooms and the whipped ricotta can be prepared a day in advance. Store them separately in airtight containers in the refrigerator. The baguette slices can be toasted a few hours ahead and stored at room temperature. Assemble just before serving for the best texture.
- Best Served Fresh: Crostini are best enjoyed shortly after assembly to prevent the bread from becoming soggy. If you anticipate leftovers (unlikely!), store the components separately and assemble them as needed.
Serving Suggestions
These roasted mushroom crostini are versatile and pair well with a variety of drinks and other appetizers.
