How to Make Mushroom & Brie Crostini
Step 1: Prepare the Baguette
Start by preheating 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’re golden brown. This step is key because it ensures that each bite has that satisfying crunch we all love!
Step 2: Cook the Mushrooms
In a large skillet, heat about 2 tablespoons of olive oil over medium heat. Add in your minced garlic and sauté just until fragrant—around one minute should do. Then, toss in those beautiful Baby Bella mushrooms! Cook them while stirring occasionally until they release their moisture and turn golden brown (about 5-7 minutes). Adding Marsala apple vinegar helps enhance their flavor while reducing down gives it that rich depth we crave.
Step 3: Assemble the Crostinis
Now comes the fun part! Lay a slice of brie on each toasted baguette slice so it covers it nicely. Spoon on that delicious mushroom mixture generously over the brie—this is where all those flavors come together!
Step 4: Bake
Transfer your baking sheet back to the oven and bake for another 3-5 minutes. Keep an eye on them because you want to pull them out just as the brie starts melting into gooey perfection.
Step 5: Serve
Once they’ve cooled for just a minute, sprinkle those gorgeous chopped parsley bits over the top before serving. They’re best enjoyed warm when that brie is still nice and gooey—trust me, you won’t be able to stop at just one! ENJOY!
Pro Tips for Making Mushroom & Brie Crostini
Creating the perfect Mushroom & Brie Crostini is all about attention to detail and a sprinkle of creativity! Here are some tips to ensure your appetizer shines at your next gathering:

Adjust the Toasting Time: Keep an eye on the baguette slices while they toast. Perfectly toasted bread adds a satisfying crunch that balances the creamy Brie and savory mushrooms.
