Step‑by‑Step Instructions for Caprese Crostini Ghosts
Step 1: Preheat and Prepare
Begin by preheating your oven to 400°F (200°C). While it’s heating, place the fresh whole-milk mozzarella in the freezer for about 10 minutes to firm it up, ensuring cleaner cuts. This step is key for achieving those adorable ghost shapes in your Caprese Crostini Ghosts!
Step 2: Slice the Baguette
While the mozzarella firms, slice your baguette diagonally into 1/2-inch thick pieces using a sharp knife. Lay them out in a single layer on a baking sheet, then generously drizzle with extra-virgin olive oil, making sure to coat each slice evenly for optimal flavor and crispness.
Step 3: Bake the Crostini
Pop the baking sheet into the preheated oven and bake the baguette slices for about 8–9 minutes or until they are golden brown and crisp. Keep an eye on them for that perfect crunch, as an ideal crostini should be firm and toast-like yet not burnt. Once done, set them aside to cool down slightly.
Step 4: Shape the Mozzarella
Retrieve the mozzarella from the freezer and slice it into planks approximately 1/2-inch thick. Use a ghost-shaped cookie cutter to punch out shapes from these mozzarella slices. Be sure to save any scraps, as they can be used later as tasty bonuses on your crostini.
Step 5: Spread the Pesto
Next, take each cooled crostini slice and spread about 1 teaspoon of vibrant pesto evenly across the top. This herbaceous layer will complement the creamy mozzarella beautifully, enhancing the flavors of your Caprese Crostini Ghosts and setting a delicious foundation.
Step 6: Add the Tomato and Mozzarella
Now, start topping half of the crostini with juicy Campari tomato slices, followed by the ghost-shaped mozzarella pieces. To make it more festive, use balsamic glaze to draw playful faces on the mozzarella ghosts. This fun detail will bring your spooky appetizers to life!
Step 7: Finish the Remaining Crostini
For the remaining crostini, layer with more tomato slices and leftover chopped mozzarella scraps. Drizzle these with balsamic glaze as well, enhancing both flavor and visual appeal. This simple step elevates your Caprese Crostini Ghosts, ensuring all guests will enjoy a delightful bite.
Step 8: Serve and Enjoy
Arrange your finished Caprese Crostini Ghosts on a serving platter, showcasing their spooky charm. It’s best to serve them immediately to maintain their crispness and vibrancy. Gather your guests around for a festive taste of Halloween with these fun and easy treats that are sure to impress!

Storage Tips for Caprese Crostini Ghosts
Room Temperature: Serve your Caprese Crostini Ghosts immediately after assembling for the best flavor and texture; they should not sit out for over 2 hours.
Fridge: If you have leftover ingredients, store them separately in airtight containers. The crostini base can last up to 3 days in the fridge, but it’s best assembled fresh.
Freezer: The baked crostini can be frozen for up to 1 month if placed in a freezer-safe bag. Reheat in a preheated oven for 5–7 minutes to regain crispness.
Reheating: To enjoy any leftovers, warm the crostini briefly in the oven rather than the microwave to keep that delightful crunch intact.
Expert Tips for Caprese Crostini Ghosts
• Mozzarella Tip: Freezing the mozzarella for 10 minutes makes it easier to cut into ghost shapes without crumbling.
• Crispy Crostini: Keep an eye on the baguette slices while baking; overcooking can lead to burnt crostini, making them too hard.
• Pesto Substitution: If you’re out of pesto, a drizzle of garlic oil can create a delightful twist while still complementing the Caprese Crostini Ghosts.
• Decoration Detail: Thicker balsamic glaze works best for drawing the spooky faces; a fine tip is key for precision!
• Serving Fresh: To maintain the ideal texture, assemble the crostini just before serving to avoid sogginess from tomatoes and pesto.

Caprese Crostini Ghosts Recipe FAQs
What type of mozzarella should I use for Caprese Crostini Ghosts?
I recommend using fresh whole-milk mozzarella for its creaminess and the ability to hold its shape when cut into ghost forms. If you can’t find it, feel free to substitute with a mix of cheeses that melt well, like mozzarella and provolone.
How should I store leftover Caprese Crostini Ghosts?
For the best experience, serve your Caprese Crostini Ghosts immediately after assembling. If you do have leftovers, store the components separately. The crostini base can be kept in an airtight container in the fridge for up to 3 days, while fresh mozzarella and pesto should also be stored separately in the fridge.
Can I freeze Caprese Crostini Crostini?
Absolutely! You can freeze baked crostini for up to 1 month. Place them in a freezer-safe bag, removing as much air as possible. When you’re ready to eat, just reheat them in a preheated oven at 400°F (200°C) for about 5–7 minutes to restore their delightful crunch.
What to do if my crostini slices get soggy?
To prevent sogginess, assemble the crostini just before serving. If they do become slightly soggy, try reheating them in the oven briefly to regain some crispness. Alternatively, serve the tomato and pesto toppings on the side, allowing guests to assemble their crostini as desired.
Are there any dietary considerations I should keep in mind for Caprese Crostini Ghosts?
These Caprese Crostini Ghosts are vegetarian-friendly, making them perfect for a variety of diets. However, if your guests have dairy allergies, you can use a vegan cheese substitute instead of mozzarella to accommodate their needs. For a nut-free option, make sure your pesto does not contain any nuts.
Can I prepare the ingredients in advance?
Yes, you can prepare the individual components in advance! Slice the baguette, make the pesto, and even slice the mozzarella a day before serving. Just store each item in airtight containers in the fridge. Assemble everything just before your Halloween gathering to ensure they are fresh and tasty!
