Ingredients
• ½ crusty baguette: The foundation for our crostini, offering a perfect crunchy texture when grilled or baked.
• ¼ cup olive oil (or butter if not vegan): Adds richness to the mushrooms while helping to achieve a perfect golden-brown crostini.
• 16 oz. cremini mushrooms, cleaned: These mushrooms are meaty and flavorful, providing the dish’s earthy base.
• 1 bunch fresh thyme leaves: Fresh thyme adds a fragrant, herbal note that elevates the mushrooms.
• 1 shallot, minced (or small onion): Provides a mild, sweet onion flavor that complements the mushrooms without overpowering them.
• ¼ cup sherry vinegar: Used to deglaze the pan, it adds acidity and depth, enhancing the overall flavor profile.
• 2 teaspoons flour: Helps thicken the sauce, giving it a luscious consistency that coats the crostini perfectly.
• ¼ cup veggie stock, broth, or water: Adds moisture and flavor to the mushroom mixture, creating a saucy topping.
• Salt & pepper to taste: Essential seasonings that bring all the flavors together.
Step-by-Step Instructions
Slice your bread into approximately ¼ inch thick slices. This ensures each crostini is the perfect thickness for a satisfying crunch without overshadowing the topping.
Brush each slice with 1-2 tablespoons of olive oil and season with salt and pepper. The oil helps the bread crisp up beautifully while the seasoning enhances its flavor.
Grill the crostini over high heat on both sides using a grill pan or outdoor grill until desired grill marks are achieved. Alternatively, bake the crostini at 450°F on the middle rack for about 7 minutes until golden brown and crispy. Set them aside to assemble the mushroom topping. This step creates the perfect base with a delightful crunch.
Slice the mushrooms no more than ¼ inch thick. Slicing them thinly allows them to cook evenly and absorb the flavors of the thyme and shallot.
In a hot skillet, add 3-4 tablespoons of butter or olive oil, then sauté the mushrooms, minced shallot, and thyme for 2 minutes. This quick sauté releases the mushrooms’ juices and infuses them with the aromatic thyme.
Deglaze the pan with sherry vinegar and let it simmer for 30 seconds. This step lifts all the flavorful bits from the bottom of the pan, adding a tangy depth to the dish.
Stir in the flour and then add the stock (or water) to create a pan sauce. The flour thickens the sauce, while the stock adds moisture and enhances the mushrooms’ natural flavors.
Adjust the consistency with more stock if needed and season with salt to taste. This ensures the sauce is the right thickness to coat the crostini without being too runny.
Remove the thyme leaves and spoon a couple of tablespoons of the mushroom mixture onto each crostini. This is where the magic happens, as the earthy, savory topping meets the crispy bread.
Garnish with additional thyme leaves and a drizzle of olive oil. These finishing touches add an extra layer of flavor and a beautiful presentation.

Patricia’s Tips for Success
Tip 1: Use fresh thyme for the best flavor. While dried thyme can work in a pinch, fresh thyme offers a more vibrant and aromatic quality.
Tip 2: Don’t overcrowd the mushrooms in the pan. Cooking them in batches if necessary ensures they brown properly rather than steaming.
Tip 3: Adjust the vinegar according to your taste. If you prefer a less tangy flavor, start with less and add more gradually.
Tip 4: For extra flavor, rub a cut clove of garlic on the warm crostini before adding the mushroom topping.
Tip 5: If you have leftovers, store the mushroom mixture and crostini separately to prevent sogginess. Reheat the mushrooms gently before serving.
Tip 6: Experiment with different mushrooms like shiitake or portobello for a twist on the classic flavor.
Tip 7: For a richer sauce, you can substitute part of the stock with a splash of cream or a dollop of crème fraîche.
Cooking Variations
Variation 1: Add a sprinkle of parmesan or vegan cheese on top for an extra layer of umami and richness.
Variation 2: Incorporate a handful of chopped walnuts or pine nuts for added texture and a nutty flavor.
Variation 3: For a spicier kick, add a pinch of red pepper flakes to the mushroom mixture.
Variation 4: Use a different type of bread, such as ciabatta or sourdough, for a distinct texture and flavor.
Variation 5: Drizzle truffle oil over the finished crostini for a luxurious, aromatic touch.
Serving Suggestions
Suggestion 1: Serve the Mushroom Thyme Crostini as part of an antipasto platter, alongside olives, cured meats, and a selection of cheeses for a Mediterranean-inspired spread.
Suggestion 2: Pair with a crisp white wine, such as Sauvignon Blanc or Pinot Grigio, to complement the earthy flavors of the mushrooms.
Suggestion 3: Offer as a starter at a dinner party, setting the tone for an elegant meal with minimal effort.
Suggestion 4: Enjoy as a light lunch alongside a fresh green salad dressed in a simple vinaigrette.
Suggestion 5: Incorporate into a brunch menu with other small bites like deviled eggs and smoked salmon toast for a delightful variety.
