I love how easy it is to whip up these little bites. Just sauté the mushrooms, pile them high, and enjoy with friends. They’re a hit every time! 🍄✨
Key Ingredients & Substitutions
Baguette: A fresh French baguette provides the perfect crunch. If you’re looking for alternatives, ciabatta or sourdough can work well too, offering a nice texture.
Mushrooms: Cremini or button mushrooms are great choices, but if you want a richer flavor, consider shiitake or portobello mushrooms. A mix of different mushrooms can also elevate the taste!
Cheese: I love using ricotta for its creaminess, but goat cheese adds a tangy kick. If you’re dairy-free, try using a vegan cream cheese or cashew spread.
Thyme: Fresh thyme has a more vibrant flavor, but if you have dried thyme on hand, that works too. Just remember, dried herbs are more concentrated, so use less!
How Do You Get the Perfectly Toasted Baguette Slices?
Getting your baguette slices just right is crucial for texture in your crostini. Here’s how:
- Preheat your oven to 375°F (190°C) for even baking.
- Brush the slices with olive oil on both sides for rich flavor and golden color.
- Toast for 8-10 minutes, watching closely to prevent burning. You want them crispy but not too brown!
- Let them cool slightly before adding toppings for the best crunch.

How Much Time Will You Need?
This delicious Mushroom Crostini recipe takes about 15 minutes of prep time and 15 minutes of cooking time, making it a quick and easy appetizer or snack!
Step-by-Step Instructions:
1. Prepare the Oven and Baguette:
Start by preheating the oven to 375°F (190°C). While the oven is heating, slice the baguette into 1/2 inch thick rounds. Arrange the slices on a baking sheet, then lightly brush each side with olive oil.
2. Toast the Bread:
Once your oven is hot, place the baking sheet with the baguette slices in the oven. Toast them for about 8-10 minutes or until they are golden and crisp. When they’re done, take them out and set them aside to cool slightly.
3. Cook the Mushroom Filling:
While the bread is toasting, heat 2 tablespoons of olive oil in a large skillet over medium heat. Add the minced garlic and sauté for about 30 seconds, until it gets fragrant. Next, toss in the sliced mushrooms and thyme. Cook, stirring occasionally, for about 8-10 minutes until the mushrooms become golden and have released their moisture. Season with salt and pepper to taste, then remove from heat.
4. Assemble the Crostini:
Take your toasted baguette slices and spread a generous layer of ricotta or goat cheese on top of each one. Use a knife or the back of a spoon for this. Then, add a spoonful of the sautéed mushrooms on top of the cheese on each slice.
5. Garnish and Serve:
For a beautiful finish, garnish each crostini with a small sprig of fresh rosemary. Serve these tasty Mushroom Crostinis immediately as a delightful appetizer or snack. Enjoy with a crisp white wine or your favorite cocktail!
Can I Use Different Types of Bread for Crostini?
Absolutely! While a baguette is traditional, you can use ciabatta, sourdough, or even whole-grain bread for a different flavor and texture. Just make sure the slices are about 1/2 inch thick for even toasting.
What Can I Substitute for the Mushrooms?
If you’re not a fan of mushrooms or have dietary restrictions, try using sautéed spinach or artichoke hearts as a topping. You can also mix in other vegetables like roasted bell peppers or zucchini for variety!
How to Store Leftover Crostini?
Although crostini are best enjoyed fresh, you can store leftovers by keeping the mushroom topping and toasted bread separate. Store mushrooms in an airtight container in the fridge for up to 3 days, and the bread in a sealed bag. Reassemble and briefly toast the bread before serving again.
Can I Make These Ahead of Time?
You can prepare the mushroom topping in advance and store it in the fridge for up to 3 days. Just toast the bread and assemble the crostini right before serving to keep everything fresh and crispy!
