This recipe may seem fancy, but it uses basic, simple to find ingredients. Here's what you'll need to make it:
- Mushrooms - To keep this appetizer easy and affordable to make, this recipe calls for button mushrooms ... and they work great here! However, you can certainly substitute different types, such as brown or wild mushrooms, if you prefer.
- Shallots - A couple shallots are a natural complement to the mushrooms, adding tons of flavor. Feel free to substitute onion in a pinch, just keep in mind that it many take longer to cook.
- Garlic - Mushrooms and garlic are so delicious together. Make sure to use fresh garlic (not jarred or powder) for the tastiest results.
- Lemon - You'll need a fresh lemon for this recipe, and you'll use it two ways: a little juice brightens up the sautéed mushrooms; and a sprinkle of lemon zest makes a pretty (and flavorful) finishing touch.
- Thyme - The mushrooms are also seasoned with fresh thyme, which is sooo delicious with the lemon and garlic (one of my favorite flavor combos).
- Butter + Olive Oil - You'll use a combination of butter and olive oil to cook the mushrooms.
- Cheese - Before adding the mushrooms to the crostini, you'll spread the mini toasts with creamy goat cheese. Not a fan of goat cheese? No worries, just check out the Variations section below for other options!
- Crostini - Homemade Crostini couldn't be easier to make. You just need a baguette, olive oil, and a pinch of salt.
This recipe is naturally vegetarian. To make it vegan, skip the cheese or substitute a non-dairy alternative (more ideas below). For gluten free crostini, use a GF baguette to make the crostini.
You'll Also Need
To prep the mushrooms, you'll need a sharp knife, as well as something to juice and zest the lemon (I have one of these classic citrus juicers, and this microplane zester is a fave kitchen tool!). A garlic press will come in handy, as well. For the crostini, you'll need a serrated knife, a pastry brush (for brushing the slices with oil before baking), and a large baking sheet or two (these sheet pans are my go-to) to bake the bread.
How to Make Mushroom Crostini
This recipe is so simple to prepare, especially if you have a helper to assemble the crostini! You'll find a detailed recipe card below, but here's an overview of the steps:
- Make crostini. Start by cutting your baguette on an angle into ¼-inch thick slices (a serrated knife works best). Then brush both sides with olive oil and top with a pinch of salt. Bake until the toasts are crisp throughout (no need to flip).
- Sauté shallots. While the bread bakes, you'll cook the filling. Begin by sautéing the shallots in butter and olive oil for a couple minutes, or until they turn translucent.
- Cook mushrooms. Next, you'll add the mushrooms, and cook them until they're browned and tender.
- Add garlic, lemon, and herbs. When the mushrooms have browned, mix in the garlic, then continue cooking just until it's fragrant. Add the lemon juice and stir well, then remove the pan from the heat. Stir in the thyme, then season the mushrooms with salt and pepper to taste.
- Assemble the crostini. To assemble, spread the toasted bread with a thin layer of goat cheese, then top with the mushrooms. Sprinkle with fresh thyme and lemon zest, and if you wish, add a drizzle of olive oil. Tip: to make sure you have enough for all the toasts, divide the toppings before you add them to the crostini.
And that's all there is to it ... your scrumptious Mushroom Goat Cheese Crostini is ready to eat! You can serve this delicious Mushroom appetizer warm or at room temperature. Either way it's sure to be a hit, so don't be surprised if your guests gobble it up within in minutes!
Tip: To save time when planning a party, prepare the crostini toasts a day or two in advance. Then store the toasts in an airtight container so they stay crisp.
Once you master this basic recipe, you can have fun experimenting! Here are some ideas to inspire you:
- Mushrooms - I used basic button mushrooms here, but if you want to impress your guests, swap in your favorite wild mushrooms.
- Cheese - Not a fan of goat cheese? Not to worry, you can easily substitute any spreadable cheese, such as brie, a creamy (or thinly sliced) feta, Boursin, or even a mild blue cheese. You could also sprinkle parmesan on top.
- Herbs - Other fresh herbs, such as rosemary or parsley, would also taste great here. Substitute them for the thyme or use a combination.
- Creamy - If you'd like to make the mushroom topping creamy, add a tablespoon (or two) of cream cheese along with the lemon juice.
- Spicy - Like your food with a little kick? Add some crushed red pepper flakes along with the garlic.
- Vegan - For a vegan option, you can skip the cheese altogether (drizzle extra olive oil over the top instead), or you can use a spreadable vegan cheese. Try it with Dairy-Free Boursin or this Miyoko's Creamery Garlic Herb Cheese.
- Gluten Free - If you're serving GF guests, don't forget to make the crostini with a gluten free baguette.
- More - Another way to change up this recipe is by adding a sauce. You can either replace the cheese with the sauce (spread it on the bread) or drizzle it over the finished app. Pesto (or Pesto Mayo) and Romesco Sauce would both be tasty.
This appetizer is ideal for enjoying year round, but it's perfect for special occasions (like Thanksgiving, Christmas, New Year's Eve, Valentine's Day, or Easter), too. Pair this Mushroom Crostini recipe with a delicious drink or cocktail (like this Classic Daiquiri or this Cranberry Moscow Mule) and a few other quick and easy snacks (such as this crowd-pleasing Cream Cheese Dip, these addictive Stuffed Dates, or this spicy Chipotle Hummus) and you have a party!
This appetizer is one of those recipes that tastes best when eaten shortly after its made (otherwise the bread gets soggy). If you think you'll have leftovers, assemble only what you think you'll eat. Then store the different components in separate containers (the mushrooms and cheese need to be refrigerated, but the toasts do not). When you're ready to eat the leftovers, gently warm the mushrooms (add more fresh herbs and squeeze of lemon, if needed), then top the toasts.

Frequently Asked Questions
Crostini (which is Italian for "little toasts") are thin, small slices of bread (typically a baguette) that have been brushed with olive oil, then baked until crisp. They're served with various toppings, such as veggies, cheeses, mushrooms, and more. Tip: The word crostini is plural; the singular version is crostino.
Crostini may be served hot, room temperature, or cold, depending on the toppings you pair it with. It's often eaten at room temperature, which makes it perfect for large parties! For this Mushroom Crostini recipe, I'd recommend serving it warm or at room temperature.
While crostini should be crunchy, it should not be hard. If your Crostini is too hard, try slicing it thinner (about ¼-inch thick is best) or choosing a bread with a lighter texture.
To keep crostini from getting soggy, make sure to assemble it just before serving (even if you make all the components, such as the toasts and toppings, in advance).
