How to Make Mushroom & Brie Crostini
Step 1: Prepare the Baguette
Start by preheating your oven to 375°F (190°C). Place your sliced baguette on a baking sheet and brush both sides with olive oil. Toast them in the oven for about 3-5 minutes until golden brown. This step helps create a sturdy base for your toppings while adding delightful crunchiness!
Step 2: Cook the Mushrooms
In a large skillet over medium heat, warm about 2 tablespoons of olive oil. Add minced garlic and sauté until fragrant—this should only take about one minute. Next, toss in those lovely sliced Baby Bella mushrooms! Stir occasionally as they cook down, releasing their moisture and turning golden brown over about 5-7 minutes. Pour in the Marsala apple vinegar and allow it to simmer until reduced by half—this adds depth to the flavor. Season with salt and pepper, plus red pepper flakes if you like it spicy!
Step 3: Assemble the Crostinis
Lay slices of brie on each toasted baguette slice so they cover each one nicely. Generously spoon your mushroom mixture right over the top of the brie—don’t be shy here! Once assembled, place them back on the baking sheet.
Step 4: Bake
Pop those beautiful crostinis back into the oven for another 3-5 minutes until the brie starts melting. This step transforms everything into an oozy delight that will have everyone excited!
Step 5: Serve
Remove from the oven and let them cool just slightly. Garnish with finely chopped parsley before serving them warm while that brie is still gooey! Trust me; they’ll disappear quickly—so enjoy every bite!
Pro Tips for Making Mushroom & Brie Crostini
Creating the perfect Mushroom & Brie Crostini is easier than you might think! Here are some tips to ensure your appetizer turns out wonderfully.
-
Use Fresh Ingredients: Fresh mushrooms and high-quality Brie cheese make a noticeable difference in flavor. It enhances the overall taste and ensures your dish is as delicious as possible.
-
Don’t Overcrowd the Skillet: When cooking the mushrooms, avoid overcrowding the pan. This allows them to brown evenly and prevents steaming, giving you that lovely golden color and rich flavor.
-
Experiment with Flavors: Feel free to add other herbs or spices! Thyme, rosemary, or even a hint of garlic powder can elevate your mushroom mixture and give it a unique twist.
-
Serve Immediately: These crostinis are best enjoyed fresh out of the oven while the Brie is melty. The quick serving ensures each bite is warm and gooey, just how it should be!
-
Make Ahead Options: If you’re short on time, prepare the mushroom mixture ahead of time. Just reheat it slightly before assembling your crostinis for a quick assembly when your guests arrive.
