Savory Blue Cheese and Mushroom Crostini Recipe

These small blue cheese and mushroom crostini are simple to prepare and perfect as a two-bite party appetizer.

Add these savory, crunchy crostini to your appetizer lineup for your next gathering. They’re a crowd-pleaser and quick to assemble. If you prefer a shortcut, use pre-toasted crostini from your grocery store deli—many stores carry a tub of ready-to-use tiny toasts. With either homemade or store-bought toasts, these bites come together fast and deliver big flavor.

Ingredients for Blue Cheese Mushroom Crostini:

• 1 baguette, sliced (or pre-made crostini/toasts)
• Blue cheese salad dressing
• White or baby bell mushrooms, sliced
• Swiss cheese, pre-sliced
• Butter (or olive oil)
• Flat-leaf Italian parsley, chopped (optional)

How to make Blue Cheese Mushroom Crostini:

• Slice the baguette: Preheat oven to 350°F (175°C) and slice the baguette into thin rounds.
• Brush with fat: Lightly brush each slice with melted butter or olive oil.
• Bake: Bake the slices for 15–20 minutes or until golden, flipping halfway to brown both sides evenly. If using pre-baked crostini, skip this step.
• Sauté mushrooms: In a skillet, sauté sliced mushrooms in 1–2 tablespoons of butter until softened and lightly browned. Let cool slightly.
• Chop mushrooms: Reserve some attractive sliced mushroom pieces for topping, and roughly chop the rest to use as a filling.
• Assemble: Spread a thin layer of blue cheese dressing on each toast. Add a spoonful of the chopped sautéed mushrooms, then top with a small slice of Swiss cheese and a reserved mushroom slice if desired.
• Broil: Place crostini under the oven broiler on low just until the Swiss melts. Watch closely to prevent burning.
• Garnish (optional): Sprinkle with chopped Italian parsley before serving.

How to store Blue Cheese Mushroom Crostini:

These crostini are best served fresh and crisp from the oven. If you have leftovers, store them covered in the refrigerator for up to two days. Reheat briefly in the oven until warm to restore some crispness.

Make-ahead tips:

You can sauté the mushrooms ahead of time and refrigerate them until you’re ready to assemble. The toasted rounds or pre-baked crostini can also be prepared in advance. Assembled crostini are great served warm or at room temperature, making them a flexible option for entertaining.

Other dips and sauces to try on crostini:

This recipe uses a blue cheese salad dressing for its bold flavor, but you can get creative with other spreads. Try any of these for variety:

• Ranch dressing
• Marinara sauce
• Buffalo hot sauce
• Mayonnaise
• Garlic butter

7. Turn on your oven’s broiler to low heat and place your pan of tiny toasts under the broiler for a short time just to melt the swiss cheese. Watch them the whole time (do not walk away during this step).
