Mushroom Brie Crostini Baguette

Mushroom and Brie Crostini elevates even the simplest gatherings with its creamy cheese and earthy sautéed mushrooms atop a crisp baguette. Balanced with a hint of Marsala wine and a touch of fresh parsley, this is my go-to appetizer whenever friends drop by unannounced. Each bite is warm, melty and loaded with flavor that feels both rustic and refined.

I first shared these at a holiday potluck and even folks who usually pass on mushrooms came back for seconds. Now I never host without them ready to go.

• Baguette: For the perfect base seek out a bakery-fresh loaf with a crisp crust and soft center
• Olive oil: Adds crispiness and subtle richness when brushed on the bread look for extra virgin olive oil
• Baby Bella mushrooms: Their deep flavor stands up to cheese and wine select firm dry mushrooms with no dark spots
• Garlic: Minced garlic gives the mushroom mixture a punchy aroma
• Marsala wine: Offers depth and a hint of sweetness choose a quality cooking Marsala from the wine section
• Brie cheese: The star for creaminess opt for a brie with a white rind that feels springy to the touch
• Salt and pepper: Essential for seasoning keep both handy to brighten all the flavors
• Fresh parsley: Adds a burst of color and freshness buy flat leaf if possible and chop just before serving
• Crushed red pepper flakes: Optional for those who want a gentle heat look for bright red flakes with no clumping

Step-by-Step Instructions

Prepare the Baguette:

Preheat your oven to a moderate temperature around three seventy five degrees Fahrenheit set your sliced baguette on a baking sheet and brush each side with olive oil. Toast in the oven for three to five minutes until both sides are golden crisp but not hard. Set these aside for topping

Cook the Mushrooms:

Warm olive oil in a large skillet over medium heat. Add minced garlic and let it sizzle just until fragrant being careful not to burn it. Next stir in sliced Baby Bella mushrooms cook them slowly so they release their moisture and steadily turn golden brown around five to seven minutes. Pour in Marsala wine and allow it to simmer away so the liquid reduces by half which intensifies the flavor. Sprinkle with salt pepper optional red pepper flakes and finish with fresh thyme or your favorite herbs then remove from heat

Assemble the Crostinis:

Top each slightly cooled baguette round with a slice of brie letting the cheese gently warm from the toasted bread. Scoop a hearty spoonful of mushroom mixture over the brie ensuring each bite gets both mushroom and cheese

Bake:

Return your topped crostinis to the oven for three to five minutes just until the brie starts to melt but does not run. The aroma at this stage is incredible

Serve:

Remove carefully let cool a minute then garnish with freshly chopped parsley. Serve these right away while still warm and gooey for the best texture and taste

Pin it

What stands out about this recipe is the way the brie melts into the crevices of the baguette. My mom always insisted on a fresh parsley finish and it still reminds me of family brunches we shared in our tiny kitchen. Brie has been our celebration cheese for as long as I can remember

Storage Tips

If you have leftovers store them in an airtight container in the refrigerator. To restore their crispiness reheat in the oven rather than the microwave. I find they are still tasty the next day though the texture is best fresh from the oven

Ingredient Substitutions

If you cannot find Baby Bella mushrooms try cremini or even a blend with shiitake for added umami. For the cheese lovers who dislike brie creamy goat cheese or camembert work too. Marsala wine can be swapped with dry sherry or even white wine for a lighter touch

Serving Suggestions

Serve these on a wooden platter with a scattering of extra parsley or even a drizzle of good olive oil at the table. They pair beautifully with sparkling wine or a crisp Chardonnay. For added color top with a few thinly sliced radishes or sprinkle of microgreens

Cultural Context

Crostini originate from Italy meaning little toasts and were traditionally used to stretch day old bread. Topped with local cheese and whatever was fresh these bites are perfect for showing off simplicity and seasonality in classic European style
