Ingredients for Mushroom Thyme Crostini Recipe
Here’s what you’ll need to make this delicious Mushroom Thyme Crostini Recipe:
½ crusty baguette: About 14 slices cut ¼” thick, ideally a day or two old for better toasting.
1-2 tablespoons olive oil: Use high-quality extra virgin for an enhanced flavor.
Salt & pepper to taste: Essential for balancing flavors, adjust to your preference.
16 oz cremini mushrooms: Cleaned and sliced no more than ¼” thick for even cooking.
1 bunch fresh thyme leaves: Provides earthy aroma and taste; fresh is best for vibrancy.
1 shallot: Minced; offers a mild onion flavor that complements the mushrooms beautifully.
3-4 tablespoons butter or olive oil: The base fat for sautéing, giving richness to the dish.
¼ cup sherry vinegar: Adds a tangy depth; feel free to substitute with red wine vinegar if necessary.
2 teaspoons flour: Handles thickening; use gluten-free flour if needed.
¼ cup vegetable stock, broth, or water: Your choice of liquid to adjust the consistency.
How to Make Mushroom Thyme Crostini Recipe
Follow these simple steps to prepare this delicious Mushroom Thyme Crostini Recipe:
Step 1: Prepare the Bread
Slice the baguette into ¼” thick pieces. Brush each slice lightly with olive oil, then sprinkle with a dash of salt and pepper. Toast the slices on a hot grill until nice grill marks appear, or bake them in a preheated oven at 450°F (230°C) for about 7 minutes until golden and crispy. Set aside to let them cool.
Step 2: Sauté Aromatics
In a large skillet, heat butter or olive oil over medium-high heat. Once hot, add the sliced cremini mushrooms, minced shallot, and fresh thyme leaves. Sauté everything together for about 2 minutes until the mushrooms soften and the shallots become fragrant.
Step 3: Deglaze the Pan
Pour in the sherry vinegar to deglaze the skillet, allowing it to simmer for about 30 seconds. This step lifts all those irresistible brown bits stuck on the pan, infusing the dish with flavor.
Step 4: Thicken the Mixture
Stir in the flour and cook for another 30 seconds, consistency is key here. Gradually add in your vegetable stock, keeping it moving until the mixture thickens to a sauce-like consistency. Add salt and pepper to taste—this is the time to adjust for your flavor preference.
Step 5: Assemble the Crostini
Take those beautifully toasted baguette slices and spoon a generous amount of your mushroom mixture on top of each slice. For the final touch, garnish with additional fresh thyme leaves and a light drizzle of olive oil to elevate those flavors even more.
Step 6: Serve and Enjoy
Transfer your stunning crostini to a platter and watch as your guests marvel at your culinary prowess. Serve them warm for the perfect bite-sized appetizer, but don’t be surprised if they disappear in moments!
