How to Make Mushroom & Brie Crostini
Step 1: Prepare the Baguette
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’re golden brown. This step is crucial as it gives the crostini that nice crunch we all love!
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—just about one minute will do. Then toss in those sliced Baby Bella mushrooms and cook until they become golden brown, which should take around 5-7 minutes. Pour in the Marsala apple vinegar and let it simmer until reduced by half; this enhances the flavors beautifully! Don’t forget to season with salt and pepper, adding red pepper flakes if you want a little kick.
Step 3: Assemble the Crostinis
Now comes the fun part! Lay a slice of brie on each toasted baguette slice so it covers every inch of that crunchy bread. Spoon a generous amount of your mushroom mixture right over that melty brie; this is where all those delicious flavors come together.
Step 4: Bake
Transfer your loaded baking sheet back into the oven and bake for about 3-5 minutes, or until you see that brie starting to melt beautifully. This is when your kitchen will smell amazing!
Step 5: Serve
Once baked, remove them from the oven and let cool for just one minute—if you can wait! Garnish with chopped fresh parsley before serving. Enjoy these crostinis warm while the brie is still gooey; they’re simply irresistible!
