Step-by-step instructions
Follow these easy steps to build warm, melty ham and cheese crostini at home.
Step 1: Slice the baguette
Cut the baguette into half-inch slices on a slight diagonal. Aim for even pieces so they toast and bake at the same rate.
Step 2: Toast the bread
Melt butter in a large skillet over medium heat. Add the baguette slices and cook until both sides turn golden and crisp.
Step 3: Dice the ham and cheese
Stack the ham and mozzarella on a cutting board. Cut them into small, even cubes so the topping stays balanced in every bite.
Step 4: Chop the tomato and herbs
Dice the tomato into small pieces and chop the parsley finely. Pat the tomato dry with a paper towel to avoid excess moisture.
Step 5: Mix the topping
Combine the diced ham, cheese, tomato, parsley, mayonnaise, and pepper in a bowl. Stir gently until everything is evenly coated.
Step 6: Top the toasted slices
Arrange the toasted baguette slices in a baking dish. Spoon a generous amount of the ham and cheese mixture onto each piece.
Step 7: Bake until bubbly
Place the dish in a preheated oven at 375°F. Bake until the cheese melts completely and the edges turn lightly golden.
Step 8: Serve right away
Remove the crostini from the oven and let them cool for one minute. Garnish with extra parsley and serve while the cheese is still stretchy.

A few simple habits keep the bread crisp and the topping perfectly melted.

Can I prepare the topping ahead of time?
Yes, mix the ham, cheese, tomato, and mayonnaise up to one day ahead. Store covered in the refrigerator and spoon onto toasted bread just before baking.

Toast the slices thoroughly in butter first and avoid adding too much topping. Serving right after baking also helps maintain the crisp texture.
