Mushroom Crostini Ingredients
For the Mushrooms
- Vermont Creamery Cultured Unsalted Butter – adds richness and depth of flavor; substitute with any high-quality unsalted butter.
- Medium Yellow Onion – provides sweetness and complexity; no direct substitute recommended, but shallots can be used for a milder taste.
- Shiitake Mushrooms – contributes a rich, earthy flavor; substitute with cremini or button mushrooms if shiitakes are unavailable.
- Brown Mushrooms – adds texture and a slightly nutty flavor; can replace with additional shiitake or any preferred mushroom variety.
- Clove of Garlic – enhances savoriness; can omit if desired or substitute with garlic powder (1/8 teaspoon).
- Marsala Wine – instills sweetness and depth to the mixture; for an alcohol-free version, substitute with chicken stock or grape juice.
- Fresh Thyme Leaves – brightens the dish and complements the earthiness of mushrooms; substitute with dried thyme (1 teaspoon) if fresh is unavailable.
- Kosher Salt – balances flavors; use table salt in lesser amounts if that’s what you have.
- Freshly Ground Black Pepper – adds warmth and mild spice; can substitute with white pepper.
For the Crostini
- Baguette – the base for the crostini; other types of bread can be used, but they should be sturdy enough to hold the topping.
Step‑by‑Step Instructions for Mushroom Crostini
Step 1: Prep the Ingredients
Begin by thinly slicing the medium yellow onion and preparing the shiitake and brown mushrooms by chopping them into chunky pieces. Mince the clove of garlic if using. Gather the remaining ingredients, including butter, Marsala wine, and fresh thyme, as well as your baguette for toasting later. Having everything ready will ensure a smooth cooking process for the delicious Mushroom Crostini.
Step 2: Cook the Onions and Mushrooms
In a large skillet, melt 4 tablespoons of cultured butter over medium heat until it bubbles. Add the sliced onion and cook for about 5 minutes until it becomes tender and golden. Next, introduce the chopped mushrooms and minced garlic, stirring occasionally. Continue cooking for another 5 minutes, allowing the mixture to soften and develop a rich golden color, which is essential for your Mushroom Crostini topping.
Step 3: Add the Flavors
Once the mushrooms and onions have caramelized beautifully, remove the skillet from the heat momentarily. Pour in a splash of Marsala wine and sprinkle in the fresh thyme leaves. Stir well to combine all the flavors before returning the skillet to medium heat. Let the mixture simmer for 5 to 7 minutes, or until it reaches a jam-like consistency, becoming deeply flavorful and aromatic, perfect for topping your crostini.
Step 4: Prepare the Baguette
While the mushroom mixture is simmering, preheat your oven to 400°F (200°C). Slice the baguette into diagonal pieces, about 1-inch thick, and spread them on a baking sheet. Brush each side of the baguette slices with the remaining melted butter to ensure they become crisp and golden. Once the oven is ready, toast the baguette for about 5-7 minutes until lightly browned and enticingly crisp on the edges.
Step 5: Assemble the Crostini
Once the baguette slices are toasted, it’s time to assemble your Mushroom Crostini. Spoon a generous amount of the warm, jammy mushroom and onion mixture atop each toasted baguette slice. Garnish with extra fresh thyme leaves for a pop of color and flavor. Arrange the crostini on a serving platter and take a moment to admire your beautiful, flavorful creation before serving it to your eager guests!
Make Ahead Options
These Mushroom Crostini are perfect for busy cooks looking to streamline their meal prep! You can prepare the caramelized mushroom mixture and store it in the refrigerator for up to 3 days. To maintain flavor and texture, be sure to let it cool completely before transferring to an airtight container. When you’re ready to serve, simply reheat the mixture gently in a skillet. Toast the baguette slices just before serving to ensure they remain crispy and golden. This simple approach allows you to enjoy the delightful flavors of Mushroom Crostini with minimal effort, making entertaining a breeze!
