Key Ingredients & Substitutions
Bread: A French baguette or Italian bread gives the best crunchy base. If you want something gluten-free, try gluten-free bread or polenta rounds for variety.
Mushrooms: I use cremini for their robust flavor, but you can also try shiitake or even portobello for a meaty texture! White mushrooms work too if that’s what you have.
Cheese: Ricotta is creamy and mild, while goat cheese adds tang. If you want a dairy-free option, try cashew cream or hummus for spreading.
How Do I Ensure My Mushrooms Are Perfectly Sautéed?
Sautéing mushrooms well is key to a great flavor. First, dry your mushrooms gently with a cloth; excess moisture will prevent them from browning properly. Heat butter over medium heat rather than high, to allow them to cook evenly.
- Add mushrooms in a single layer, giving them space. Crowding the pan will steam them instead!
- Let them sit undisturbed for a few minutes so they can brown nicely before stirring.
- Don’t rush the process; patience here leads to deep flavor and caramelization. Enjoy the aroma as they cook!

How Much Time Will You Need?
This delicious mushroom crostini recipe will take about 30 minutes total—10 minutes for prep and about 20 minutes for cooking and assembling. Perfect for an appetizer or snack at any gathering!
Step-by-Step Instructions:
1. Prepare the Bread:
Start by preheating your oven to 375°F (190°C). While the oven is heating, place your sliced bread on a baking sheet. Lightly brush both sides of each slice with olive oil. This will help them toast up nice and crispy!
2. Toast the Bread:
Pop the baking sheet into the oven and toast the bread for about 8-10 minutes. Remember to turn the slices halfway through so they brown evenly. You want them golden and crisp!
3. Cook the Mushrooms:
While the bread is toasting, grab a large skillet and heat the butter over medium heat. Once melted, add your sliced mushrooms and sauté for about 5-7 minutes. They should start to brown and release their juices. Stir occasionally to ensure they cook well.
4. Add Garlic and Herbs:
Next, stir in the minced garlic and chopped rosemary. Cook for another 1-2 minutes until you can smell that delicious aroma. Season with salt and freshly ground black pepper to taste. Remove from heat.
5. Assemble the Crostini:
Once your bread is toasted, spread a generous layer of ricotta or goat cheese on each slice. Top each one with a spoonful of the warm mushroom mixture. Make it as hearty as you like!
6. Garnish and Serve:
For the finishing touch, garnish your crostini with fresh rosemary sprigs and a sprinkle of crushed red pepper flakes or dried herbs if desired. Serve immediately and enjoy your delicious mushroom crostini!
Can I Use Different Types of Bread for Crostini?
Absolutely! While a French baguette or Italian loaf is traditional, you can use any sturdy bread you like. Try ciabatta, sourdough, or even gluten-free options if you prefer.
What If I Don’t Have Fresh Rosemary?
No worries! If you don’t have fresh rosemary, you can use dried rosemary or substitute with another herb, such as thyme or parsley for a different flavor profile.
Can I Make This Recipe Vegan?
Yes, you can! Simply replace the butter with vegan margarine or olive oil, use a plant-based cream cheese or hummus instead of ricotta or goat cheese, and ensure your bread is vegan-friendly.
How Should I Store Leftovers?
Leftover crostini are best enjoyed fresh, but if you have some left, store them in an airtight container in the fridge for up to 2 days. To reheat, pop them in the oven for a few minutes to crisp them back up!
