Quick, Creamy, and Delicious Mushroom Crostini Recipe
This creamy mushroom crostini will impress your guests over and over again. Enjoy this simple and fancy appetizer for any occasion.
This mushroom toast is so good! Do you like making toasts? I had forgotten that I even had this great recipe. You can make this mushroom toast with any kind of mushrooms you like!
Besides that, toast recipes are generally so versatile. If you don’t have one ingredient on hand, you can substitute it for another. It can make the recipe be a pasta recipe instead of a toast recipe!
This recipe has that unique option, so mix it up if you want! Keep this recipe on hand (or bookmarked) for when you want to add some veggies to your pasta or need an appetizer idea.

What can you serve with this mushroom mixture?
I enjoy this recipe on a nice slice of fresh bread, but you can also:
- Leave the bread out and make it a simple mushroom side dish.
- Leave the bread out and serve over rice, mashed potatoes, couscous, or even pasta!
- Add another slice of bread and make it a mushroom melt sandwich.
Did you know mushrooms improve nutrition and promote better diet quality? Also, mushrooms give your body vitamin D, which is great timing for this recipe, since summer is over for now. Mushroom toast makes a great appetizer, lunch, or party treat (like for game day!).
Toasting and Baking the Bread for Crostini
Preheat the oven to 375F. As soon as the mushroom mix is ready, spoon some on each slice of bread. Then pop the baking tray into the preheated oven and bake for 5-7minutes, until the bread is slightly crispy and the edges are toasty.
You can use pretty much any kind of mushrooms for mushroom crostini. I like to use brown mushrooms like cremini, baby bella or white mushrooms. They hold there shape well when cooking.

Expert Tips
- Combine button mushrooms with a variety of mushrooms: oyster, shiitake, or cremini mushrooms for a deeper, more complex flavor profile.
- Gently clean mushrooms with a damp paper towel instead of washing them directly to avoid excess moisture.
- Substitute the butter for extra virgin olive oil if you don’t have any on hand. Alternately, use a combination of olive oil and butter.
- Deglaze the pan with a splash of white wine or lemon juice. This can also add depth of flavor.
- Season with black pepper for more flavor. Do this mid-cooking so the mushrooms can absorb the flavor.
- Make sure the bread is toasted to a perfect golden brown to provide a crunchy base. Add an equal amount of mushroom mix to each bread slice for even toasting.
Recipe FAQs
Yes, you can make it a day ahead and reheat gently.
Brush with olive oil before toasting and serve soon after assembly.
Cut a garlic clove in half and add a garlic rub to the bread before laying on the mushroom mixture. This will enhance the garlic taste in the bread, not just the mushroom topping.
