This Mushroom Crostini is a tasty treat perfect for gatherings! Crunchy bread topped with savory mushrooms and cheese makes it hard to resist.
Honestly, it’s like a little party on a slice of toast! I love serving these at home. They disappear quickly, and I always wish I made more! 🍄✨
Key Ingredients & Substitutions
Baguette: A French baguette gives that perfect crunch. If you’re gluten-free, you can use gluten-free bread or ciabatta, which also works well!
Mushrooms: I love using cremini for their rich flavor, but button mushrooms are great too. If you’re feeling adventurous, try shiitake or portobello for a deeper taste.
Ricotta Cheese: This creamy cheese spreads nicely on the baguette. If you’re looking for a vegan option, cashew cream or a plant-based ricotta could be a tasty substitute.
Olive Oil: A good quality olive oil enhances the flavors. If you’re out, you could use melted butter for a different twist. Just keep that richness in mind!
How Do I Toast Baguette Slices Perfectly?
Toasting the baguette right is key to a nice crunchy base for toppings. Follow these steps to ensure perfect results:
- Preheat your oven to 375°F (190°C) for even toasting.
- Slice your baguette about 1/2-inch thick. This thickness is perfect for holding toppings.
- Arrange the slices on a baking sheet and brush with olive oil to help them brown nicely.
- Keep an eye on them as they toast, around 8-10 minutes. Look for a golden brown color!
- Don’t be afraid to flip them halfway through for even crisping.
Perfectly toasted slices will hold your delicious toppings without getting soggy. Enjoy assembling your crostini!

Delicious Mushroom Crostini Recipe
Ingredients You’ll Need:
For the Crostini:
- 1 French baguette or similar crusty baguette, sliced into 1/2-inch slices
- 2 cups mushrooms, sliced (such as cremini or button mushrooms)
- 2 tablespoons olive oil, divided
- 2 cloves garlic, minced

- 4 ounces ricotta cheese
- 1 tablespoon fresh parsley, chopped (optional for garnish)
How Much Time Will You Need?
This delightful Mushroom Crostini recipe will take about 15 minutes for prep and another 10-15 minutes for cooking. So, in about 30 minutes, you’ll have a fantastic appetizer ready to serve!
Step-by-Step Instructions:
1. Prepare the Baguette:
Start by preheating your oven to 375°F (190°C). Once it’s hot, arrange the baguette slices on a baking sheet in a single layer. Lightly brush each slice with 1 tablespoon of olive oil. Pop the baking sheet into the oven and toast for about 8-10 minutes until they’re golden brown and crisp. When done, remove the slices from the oven and set them aside.
2. Sauté the Mushrooms:
While the bread is toasting, grab a large skillet and heat the remaining 1 tablespoon of olive oil over medium heat. Add in the minced garlic and sauté for about 30 seconds until you can smell the lovely aroma. Then, toss in the sliced mushrooms and chopped rosemary. Sauté everything together for about 6-8 minutes, stirring occasionally, until the mushrooms are soft and golden brown. Don’t forget to season with salt and pepper to your liking!
3. Assemble the Crostini:
Now it’s time to bring it all together! Take each toasted baguette slice and spread a generous layer of ricotta cheese on top. Once they are all beautifully topped, spoon the sautéed mushrooms over the ricotta. Don’t be shy—load them up!
4. Garnish and Serve:
Finish off your crostini by garnishing each one with a sprinkle of fresh parsley and a tiny sprig of rosemary. These little touches give them that extra flair! Serve immediately as a delicious bite-sized starter that’s sure to impress your guests.
Enjoy the perfect balance of crispy bread, creamy ricotta, and savory, aromatic mushrooms in every bite!
Can I Use Different Types of Bread for the Crostini?
Absolutely! While a French baguette works best for crunch, you can use ciabatta, sourdough, or even gluten-free bread if preferred. Just ensure it’s sturdy enough to hold the toppings!
What Can I Substitute for Ricotta Cheese?
If you need a substitute, mascarpone cheese can provide a similar creamy texture. For a vegan option, try cashew cream or a store-bought plant-based ricotta, which works well in this recipe.
How Should I Store Leftover Crostini?
If you have any leftovers, store the toasted baguette slices separately from the mushroom topping. Place them in an airtight container in the fridge for up to 2 days. When ready to eat, reheat the crostini in the oven for a few minutes to crisp them up again!
Can I Prepare the Mushrooms Ahead of Time?
Yes, you can sauté the mushrooms in advance! Just keep them in the refrigerator for up to 2 days. When you’re ready to serve, warm them up slightly before assembling the crostini.
