The Ghostly Kitchen: The Essential Ingredients & Tools

This iconic party treat uses just a handful of smart shortcuts and fresh ingredients to create its signature spooky look and delicious flavor.

  • The Mozzarella Ghosts (The Star of the Show!):
    • Fresh Mozzarella: For the best, most authentic flavor and the perfect texture for cutting, it is essential to use a high-quality, fresh, whole-milk mozzarella. The kind that is sold in a log or a large ball (not the pre-shredded, low-moisture kind) is what you’ll need.
    • The Freezing Trick: This is the number one, non-negotiable secret to getting beautiful, clean, and perfect shapes out of soft, fresh mozzarella! By placing the mozzarella in the freezer for just 10 minutes, you are firming it up just enough so that you can easily slice it and press a cookie cutter through it without the cheese squishing or tearing.
    • The Cookie Cutter: A small, simple, ghost-shaped cookie cutter is the key tool for this recipe.
  • The Crostini Base: A fresh, high-quality baguette is the perfect choice for creating a crispy, yet slightly chewy, crostini that is sturdy enough to hold all the delicious toppings.
  • The “Caprese” Flavors: The classic and unbeatable combination of fresh, creamy mozzarella, sweet Campari or Roma tomatoes, and the fragrant, herbaceous flavor of basil (from the store-bought pesto).

The final, fun step before assembling is to use your favorite, spooky cookie cutter to cut out the cute and creepy ghost shapes from your chilled and firmed-up slices of fresh mozzarella.

Step-by-Step to the Best Caprese Crostini Ghosts

This fun and festive treat is incredibly simple to prepare.

Step 1: Make the Crispy Crostini and Prepare the Ghosts

Step 1: First, preheat your oven to 400°F (200°C).

Step 2: Place your 16 ounces of fresh mozzarella in the freezer to let it firm up for 10 minutes.

Step 3: While the mozzarella is chilling, slice your baguette diagonally into 1/2-inch-thick slices. Spread the slices evenly on a baking sheet, drizzle them with olive oil, and toss to coat.

Step 4: Bake for 8 to 9 minutes, until the crostini are golden and crisp. Let them cool completely.

Step 5: Remove the mozzarella from the freezer. Slice it lengthwise into six, 1/4-inch-thick planks. Use your ghost-shaped cookie cutter to cut the slices into your spooky ghost pieces. Roughly chop all the remaining mozzarella scraps.

Part 2: Assemble Your Spooky Bites

Step 1: Spread about 1 teaspoon of your pesto on each of the cooled crostini.

Step 2: Top 6 of the crostini with a few of your thin tomato slices, and then place one of your mozzarella ghosts on top.

Step 3 (The Fun Part!): Pour your 1 teaspoon of balsamic glaze into a small bowl. Use a chopstick or the flat end of a wooden skewer to dot the ghosts with two little eyes and a spooky mouth.

Step 4: Top your remaining crostini with one slice of tomato and a tablespoon of your chopped mozzarella scraps. Drizzle these non-ghost crostini with some more of the balsamic glaze.

Transfer the ghost crostini to a small plate to make them the star of the show, and arrange the rest of the crostini on a larger platter. Serve immediately!

Frequently Asked Questions (FAQs)

Q1: What is the absolute, number one secret to cutting fresh mozzarella into clean, perfect shapes without it squishing?

The secret is to chill it in the freezer! By placing your log of fresh mozzarella in the freezer for just 10 to 15 minutes, you are making it just firm enough to easily slice and to press a cookie cutter through cleanly, without it tearing or losing its shape.

Q2: Can I make these Halloween crostini ahead of time for a party?

Yes, this is a perfect make-ahead appetizer! You can prepare all your components—the toasted crostini, the mozzarella ghosts, and the sliced tomatoes—a day in advance and store them in separate, airtight containers. Then, the final, fun assembly will take just a few minutes right before your party starts.

Q3: Can I make these with a different spooky shape?

Yes, absolutely! This fun technique would also be fantastic with a small, pumpkin-shaped or a bat-shaped cookie cutter. You could even use a slice of a bright, orange cheddar cheese to make some cute Jack-O’-Lanterns.

Q4: Can I make this recipe gluten-free?

Of course! To make this recipe completely gluten-free, simply substitute the baguette with your favorite brand of a gluten-free baguette or a sturdy, gluten-free cracker.

Q5: What is the difference between regular, low-moisture mozzarella and fresh mozzarella?

Fresh mozzarella is a soft, fresh cheese with a high moisture content and a mild, milky flavor. It is typically sold in a ball or a log, often packed in water or whey. Low-moisture mozzarella is the firmer, saltier, and more aged version that is typically sold in a block or pre-shredded, and it is the classic choice for pizza because it melts so well. For this fresh, no-bake appetizer, you want to use the soft, fresh mozzarella.
