How to Make Mushroom & Brie Crostini
Step 1: Prepare the Baguette
First things first! Preheat your oven to 375°F (190°C). Place those lovely baguette slices on a baking sheet and brush both sides with olive oil. Toast them in the oven for about 3-5 minutes until they are golden brown. This step adds crunch and enhances the flavor of your crostinis!
Step 2: Cook the Mushrooms
In a large skillet, heat about 2 tablespoons of olive oil over medium heat. Add the minced garlic and sauté until fragrant—about one minute should do. Then, toss in those sliced Baby Bella mushrooms! Cook them while stirring occasionally until they turn golden brown and release their moisture—this should take around 5-7 minutes. Pour in the Marsala apple vinegar and let it simmer until reduced by half. Don’t forget to season with salt, pepper, and optional red pepper flakes for some heat!
Step 3: Assemble the Crostinis
Now comes the fun part! Place a slice of brie on each toasted baguette slice so that it covers every delicious inch. Spoon a generous amount of that savory mushroom mixture right over the brie. Once loaded up, put those crostinis back on the baking sheet.
Step 4: Bake
Pop that baking sheet back into the oven for another 3-5 minutes, just until you see the brie starting to melt. The aroma filling your kitchen will be irresistible!
Step 5: Serve
Remove from the oven and let them cool slightly before garnishing with freshly chopped parsley. Serve immediately while they’re warm and gooey—you won’t want to miss this moment! Enjoy every bite of these delightful Mushroom & Brie Crostini with your friends and family!
