Ingredients & Substitutions
Baguette or Italian Bread: A good crusty bread is essential for crostini. You can substitute with a sourdough loaf or ciabatta for different flavors and textures.
Basil Pesto: Store-bought pesto is convenient, but homemade pesto tastes even better! If you need a nut-free option, use sunflower seeds or omit them entirely.
Fresh Mozzarella: I love using bocconcini for their bite-sized charm. If you can’t find fresh mozzarella, you can use mozzarella cheese sticks or even feta for a different twist.
Cherry or Grape Tomatoes: These are perfect because of their sweetness. If they’re out of season, try using sun-dried tomatoes for a rich, deep flavor.
How Can I Get the Perfect Toast on My Crostini?
Getting the right toast on your crostini can sometimes be tricky. Here are some tips to ensure they come out perfect every time:
- Preheat your oven before putting the bread in. A hot oven helps achieve an even, golden toast.
- Brush olive oil on both sides for extra crispiness and flavor. Don’t be shy—go generous!
- Keep an eye on the bread as it toasts. Different ovens can vary in heat, so start checking around the 8-minute mark.
Following these tips will help you get crostini that’s crunchy on the outside and perfect for holding all those delicious toppings!

Time Needed
This amazing dish will take you about 15 minutes to make from start to finish! With a quick bake and some easy assembly, you’ll have a delicious appetizer on the table in no time!
Step-by-Step Instructions:
1. Preheat the Oven:
Start by preheating your oven to 375°F (190°C). This ensures the bread will toast perfectly while you prepare your toppings.
2. Toast the Bread:
Arrange the sliced bread on a baking sheet in a single layer. Use a brush to lightly coat each slice with olive oil. This will give them a crispy texture and golden color. Bake in the oven for about 8-10 minutes until they are nice and crunchy. Keep an eye on them to avoid burning!
3. Spread the Pesto:
Once the bread is toasted and slightly cooled, grab that tasty basil pesto! Spread a generous amount on each toasted slice, ensuring every bite will be full of flavor.
4. Add Mozzarella and Tomatoes:
Next, place a slice of fresh mozzarella on each crostini, followed by a handful of halved cherry or grape tomatoes. This adds a beautiful pop of color and a burst of freshness!
5. Season Deliciously:
Drizzle a tiny bit more olive oil over the toppings, and sprinkle a little salt and freshly cracked black pepper on top. This elevates the flavors even more.
6. Final Baking (Optional):
If you like your mozzarella nice and warm, pop the crostini back in the oven for just 3-5 minutes. Otherwise, you can serve them right away!
7. Garnish and Serve:
Before serving, add fresh basil leaves for a delightful finish and a light sprinkle of coarse sea salt for that extra crunch. Arrange them beautifully on a wooden platter and enjoy your delightful snack!
This combination of crispy bread, flavorful pesto, creamy mozzarella, and juicy tomatoes is sure to impress your friends and family. Enjoy your Pesto Tomato Mozzarella Crostini!
Can I Use Store-Bought Pesto for This Recipe?
Absolutely! Store-bought pesto saves time and works perfectly for this recipe. Just make sure to choose a good quality brand for the best flavor.
What If I Can’t Find Fresh Mozzarella?
If fresh mozzarella isn’t available, you can use shredded mozzarella or even feta cheese as a delicious alternative. Just keep in mind that the flavor will be slightly different, but still delicious!
Can I Make These Crostini in Advance?
Yes, you can prepare the toasted bread and toppings ahead of time. Just store the toasted bread in an airtight container at room temperature for up to a day. Assemble just before serving to keep everything fresh!
How Should I Store Leftover Crostini?
While crostini are best enjoyed fresh, any leftovers can be stored in an airtight container in the fridge for up to 2 days. To reheat, place them on a baking sheet and warm in the oven until the bread is crispy again!
