It was a moment of pure culinary bliss, a reminder that the best things in life are often the simplest. I’ve been chasing that perfect crostini ever since, and this recipe comes incredibly close!

Recipe Overview

• Prep Time: 15 minutes
• Cook Time: 12 minutes
• Total Time: 27 minutes
• Yields: 36 slices
• Dietary Type: Vegetarian

Ingredients

• 1 loaf unsliced Italian bread, about 16 ounce loaf
• 1/3 cup olive oil
• 1 garlic clove, finely chopped
• 1/4 teaspoon salt
• 1/4 teaspoon pepper
• 1/2 cup sliced green onion
• 5 -7 plum tomatoes, cut into 36 slices
• 1 1/2 cups shredded mozzarella cheese

Equipment Needed

• Large baking sheet
• Aluminum foil
• Small bowl
• Pastry brush
• Knife
• Cutting board

Instructions

1. Begin by preparing the bread. Cut the Italian bread into 36 even slices, about 1/2-inch thick. Aim for consistent thickness to ensure uniform toasting.

2. Preheat your oven to 400ºF (200ºC). Line a baking sheet with aluminum foil. This will prevent the crostini from sticking and make cleanup a breeze.

3. Arrange the bread slices in a single layer on the prepared baking sheet. Ensure they are not overlapping to allow for even browning.

4. Bake the bread slices in the preheated oven for 5 minutes, or until they are lightly browned and crisp around the edges. Keep a close eye on them, as they can burn quickly. This step is crucial for developing a sturdy base that can hold the toppings.

5. While the bread is toasting, prepare the garlic-infused oil. In a small bowl, combine the olive oil, finely chopped garlic, salt, and pepper. The garlic will infuse the oil with its aromatic flavor, adding depth to the crostini.

6. Once the bread is lightly browned, remove it from the oven. Using a pastry brush, generously brush each slice with the garlic-infused olive oil. Be sure to coat the entire surface of each slice for maximum flavor.

7. Evenly top the bread slices with the sliced green onions. Distribute them evenly to ensure each crostini has a balanced flavor.

8. Arrange one or two tomato slices on top of the green onions on each bread slice. Plum tomatoes are ideal because they have a firm texture and less water content, preventing the crostini from becoming soggy.

9. Generously sprinkle the shredded mozzarella cheese evenly over the tomatoes. Make sure each slice is well-covered to create a gooey, cheesy topping.

10. Return the baking sheet to the oven and bake for an additional 5 to 7 minutes, or until the cheese is completely melted and bubbly. Watch carefully to prevent burning. The cheese should be golden brown and slightly caramelized for the best flavor.

11. Remove the baking sheet from the oven and let the crostini cool slightly before serving.

12. If desired, garnish with additional sliced green onions for a pop of color and freshness.

Expert Tips & Tricks

• For an extra layer of flavor, consider adding a pinch of red pepper flakes to the garlic-infused oil. This will add a subtle kick of heat.
• If you don’t have fresh garlic, you can substitute with 1/4 teaspoon of garlic powder. However, fresh garlic provides a more pronounced and authentic flavor.
• To prevent the crostini from becoming soggy, use day-old bread. It will be drier and absorb less moisture from the tomatoes and cheese.
• If you’re short on time, you can use pre-sliced Italian bread. However, slicing your own bread allows you to control the thickness and ensures a more even bake.
• For a richer flavor, try using fresh mozzarella instead of shredded. Just be sure to slice it thinly so it melts evenly.
• You can prepare the garlic-infused oil and slice the tomatoes and green onions ahead of time. Store them separately in the refrigerator until you’re ready to assemble the crostini.

Serving & Storage Suggestions

Serve the mozzarella crostini immediately while the cheese is still warm and melted. They are best enjoyed fresh. Arrange them on a platter and garnish with fresh herbs, such as basil or parsley, for a visually appealing presentation.

Leftover crostini can be stored in an airtight container in the refrigerator for up to 2 days. However, they will lose some of their crispness. To reheat, place them on a baking sheet and bake at 350°F (175°C) for a few minutes, or until heated through. You can also reheat them in a toaster oven.

It is not recommended to freeze mozzarella crostini, as the texture of the bread and cheese will be affected.
