Mushroom crostini are delicious little bites that make a perfect appetizer! Tasty mushrooms are sautéed and served on crispy toasted bread, topped with cheese and herbs.
These treats are so easy to make, I often whip them up for friends. Just toast the bread, load it with mushrooms, and watch them disappear like magic! 🪄
Ingredients & Substitutions
Baguette: A fresh baguette adds the perfect crunch. If you can’t find one, try using ciabatta or even a gluten-free bread for a tasty alternative.
Mushrooms: Cremini mushrooms are my favorite for their rich flavor, but you can also use button mushrooms or even a mix of wild mushrooms for a more complex taste.
Cheese: I love using ricotta for its creaminess, but goat cheese gives a lovely tang. If you’re vegan or lactose intolerant, try a plant-based cream cheese instead!
White Wine: The wine adds depth to the mushrooms, but you can substitute it with vegetable broth or omit it entirely if preferred.
How Can I Get My Mushrooms Perfectly Sautéed?
Sautéing mushrooms can be tricky if you want them perfectly browned and flavorful. The key is to not overcrowd the pan. This allows them to cook evenly and brown nicely.
- First, heat your skillet on medium-high heat. This ensures the mushrooms sear rather than steam.
- Add the mushrooms in a single layer, leaving some space between them. Cook them for about 7-8 minutes.
- Stir only occasionally. Let them sit to develop that lovely browned color.
- Finally, add garlic and herbs near the end to keep their flavors fresh.
By following these simple steps, your mushrooms will shine in the crostini!

How Much Time Will You Need?
This delightful mushroom crostini recipe takes about 25 minutes total—10 minutes for prep and 15 minutes for cooking. Within no time, you’ll have a yummy appetizer ready for sharing!
Step-by-Step Instructions:
1. Prepare the Bread:
First, preheat the oven to 375°F (190°C). Take your sliced baguette and arrange it neatly on a baking sheet. Brush each slice lightly with olive oil on both sides to help them turn golden and crisp when toasted. Pop them in the oven for about 8-10 minutes, flipping once, until they’re beautifully golden. Once done, remove and let them cool for a bit.
2. Sauté the Mushrooms:
While the bread is toasting, grab a large skillet and heat 2 tablespoons of olive oil over medium-high heat. Once the oil is hot, add your sliced mushrooms. Sauté these for about 7-8 minutes, stirring occasionally, until they start to brown and release their delicious moisture.
3. Add Garlic and Herbs:
Next, toss in the minced garlic and fresh thyme leaves. Give it a quick stir and cook for an additional 1-2 minutes, allowing the garlic to become fragrant. If you’re using the white wine, pour it in now, and scrape up any tasty bits from the pan. Let it cook until the wine has mostly evaporated, which should take around 3 minutes.
4. Season the Mixture:
Once the mushrooms are perfectly cooked, season them generously with a sprinkle of salt and freshly ground black pepper. Take the pan off the heat when you’re happy with the seasoning.
5. Assemble the Crostini:
Now it’s time to assemble! Spread a generous layer of ricotta or goat cheese on each toasted baguette slice. Then, top each cheese-covered slice with a spoonful of the sautéed mushrooms you just made.
6. Garnish and Serve:
Finally, finish off by garnishing each crostini with extra fresh thyme or parsley leaves for a pop of color and freshness. Serve these beautiful bites immediately while they’re still crisp and warm. Enjoy your elegant and mouthwatering mushroom crostini!
Can I Use Other Types of Bread for Crostini?
Absolutely! While a baguette is traditional, you can use ciabatta, sourdough, or even gluten-free bread. Just be sure to slice it evenly and toast it until crispy for the best results!
How Should I Store Leftover Crostini?
It’s best to store leftover components separately. Keep the sautéed mushrooms in an airtight container in the fridge for up to 3 days. The toasted bread can also be stored at room temperature, but it may lose its crispness. To reassemble, simply reheat them briefly in the oven before serving.
Can I Make the Mushroom Filling Ahead of Time?
Yes, you can! The mushroom mixture can be prepared a day in advance, cooled, and stored in the fridge. Just reheat it gently in a skillet before spooning it onto the bread!
What Can I Add to the Mushroom Filling for Extra Flavor?
Feel free to get creative! You can add some grated Parmesan cheese, a splash of balsamic vinegar, or even some chopped sun-dried tomatoes for added depth. Fresh herbs like basil or oregano also work well!
