Mozzarella and Spinach Crostini: A Taste of Italy in Every Bite

The first time I tasted something similar to this crostini, I was backpacking through Tuscany. I stumbled upon a tiny trattoria tucked away in a sun-drenched alley in Florence. The aroma of garlic, warm bread, and melting cheese filled the air. The nonna, a woman who exuded warmth and the wisdom of generations of cooks, served me a simple crostini piled high with spinach and mozzarella. It was the perfect bite – crunchy, creamy, and bursting with fresh flavors. It was a revelation, and I’ve been chasing that perfect bite ever since. This recipe comes pretty darn close.

Recipe Overview

Prep Time: 15 minutes
Cook Time: 10 minutes
Total Time: 25 minutes
Servings: 24-36 slices
Dietary Type: Vegetarian

Ingredients

1 loaf thin French bread
2 teaspoons garlic salt
1 1/2 cups fresh spinach
4 ounces cream cheese, softened
8 ounces mozzarella cheese, thin slices

Equipment Needed

Baking Sheet
Saucepan
Colander
Broiler

Instructions

Begin by preparing the foundation: Cut the French bread in half lengthwise. This creates two long halves, perfect for topping.
Place the cut sides of the French bread halves face up on a baking sheet.
Toast the bread: Put the baking sheet into a preheated 350-degree Fahrenheit oven. Bake until the bread is lightly browned, approximately 5-7 minutes. Keep a close watch; you want a gentle toasting, not a burnt offering.
Remove the baking sheet from the oven and sprinkle the toasted bread generously with garlic salt. The amount will depend on your taste, but don’t be shy – it adds a wonderful savory note.
Prepare the spinach: In a saucepan, combine the fresh spinach with a small amount of water, just enough to create some steam.
Cook the spinach until it is tender, this should take only a few minutes. It will wilt down considerably.
Drain the cooked spinach thoroughly in a colander.
This is crucial: Squeeze out all the moisture from the spinach. Excess water will make your crostini soggy, so use your hands or even squeeze it against the colander with a spoon or spatula.
In a bowl, combine the drained and squeezed spinach with the softened cream cheese. Mix well until the spinach is evenly incorporated and the mixture is smooth.
Spread the spinach and cream cheese mixture evenly over the cut sides of the toasted French bread halves. Make sure to get right to the edges.
Arrange the mozzarella cheese slices evenly over the spinach mixture. Cover the entire surface, overlapping the slices if necessary.
Now, the final flourish: Place the baking sheet with the prepared crostini under a preheated broiler.
Broil until the mozzarella cheese is melted and bubbly, about 2-3 minutes. Watch very carefully to prevent burning; broilers can be fierce.
Remove the baking sheet from the broiler. Let the crostini cool slightly before slicing.
Slice the crostini into 1- or 2-inch pieces to serve.

Expert Tips & Tricks

Toast the Bread Just Right: The toasting step is important because it prevents the crostini from becoming soggy. Don’t over-toast, though, or it will be too hard to bite into. A light golden-brown is perfect.
Dry Spinach is Key: As mentioned, removing all excess moisture from the spinach is critical. You can even use paper towels to blot it dry after squeezing it.
Softened Cream Cheese is Your Friend: Make sure your cream cheese is truly softened before mixing it with the spinach. This will make it much easier to combine and create a smooth, spreadable mixture.
Broiler Vigilance: Broiling can be tricky. Keep a close eye on the crostini while it’s under the broiler to prevent the cheese from burning. If it’s browning too quickly, move the baking sheet to a lower rack or reduce the broiler heat.
Add a Touch of Heat: For a little extra kick, consider adding a pinch of red pepper flakes to the spinach and cream cheese mixture.
Fresh Garlic Boost: While the recipe calls for garlic salt, fresh garlic is always a welcome addition. Mince a clove or two and sauté it briefly in olive oil before adding it to the spinach mixture.
Make Ahead for Easy Entertaining: You can prepare the spinach and cream cheese mixture ahead of time and store it in the refrigerator for up to 24 hours. You can also toast the bread in advance. Assemble and broil just before serving.

Serving & Storage Suggestions

Serve the Mozzarella and Spinach Crostini immediately while the cheese is still warm and melted. Arrange the slices attractively on a platter. A sprinkle of fresh parsley or a drizzle of olive oil can elevate the presentation. These are fantastic as an appetizer for any Italian-themed meal or as a snack with a glass of crisp white wine.

Leftover crostini can be stored in an airtight container in the refrigerator for up to 2 days. The bread will soften, but the flavor will still be delicious. To reheat, you can toast them in a toaster oven or under the broiler for a few minutes. Be careful not to burn them. Microwaving is not recommended as it can make the bread soggy.

Do not leave the crostini at room temperature for more than two hours due to the dairy content of the cheese.
