Time Breakdown
Prep time : 5 min | Cooking time : 10 min | Total time : 15 min | Servings : 12 serves
Key Ingredients
- 1 French baguette, sliced into 1/2 inch rounds
- 1/4 cup extra virgin olive oil
- 3 cloves fresh garlic, minced
- 1 tablespoon fresh parsley, finely chopped
- 1 teaspoon dried oregano
- 1/2 cup freshly grated parmesan cheese
- A pinch of flaked sea salt (optional for finishing)

Step-by-Step Instructions
- Preheat your oven to 400 degrees Fahrenheit and line a large baking sheet with parchment paper to prevent sticking.
- In a small bowl, whisk together the olive oil, minced garlic, fresh parsley, and dried oregano. Letting these sit for a few minutes allows the garlic flavor to really infuse into the oil.
- Arrange the baguette slices on your prepared baking sheet in a single layer so they toast evenly.
- Brush the top of each bread slice generously with the garlic-herb oil mixture, ensuring you get plenty of the minced garlic bits on each piece.
- Place the tray in the oven and bake for about 8 to 10 minutes, or until the edges of the bread start turning a lovely golden brown color.
- Remove the tray carefully, sprinkle each toast with a generous amount of grated parmesan, and place them back under the broiler for 1 to 2 minutes. Watch them closely during this step so the cheese turns golden and bubbly rather than burnt.
- Remove from the oven, sprinkle with an extra pinch of sea salt if desired, and serve while still warm for the best crunch.
Serving Suggestions
- Top them with a fresh tomato and basil bruschetta mix. The acidity of the tomatoes cuts through the richness of the parmesan beautifully.
- Serve alongside a bowl of creamy roasted red pepper dip. The smokiness of the peppers complements the garlic herb base of the crostini.
- Include them on a Mediterranean-themed charcuterie board. They pair wonderfully with olives, marinated artichokes, and soft cheeses.
- Use them as a crunchy base for a tapenade made of kalamata olives and capers. The saltiness of the olives makes for a sophisticated and savory bite.
Storage and Make-Ahead Tips
To store your leftovers, place any uneaten crostini in an airtight container at room temperature for up to two days, or in the refrigerator if you prefer them firm. If they lose their crunch, you can toast them in a low-temperature oven for a few minutes to revive the texture. They will store well, but they are undeniably freshest when served immediately after the initial bake.
If you want to freeze these, ensure they have cooled completely before storing them in a freezer-safe bag for up to one month. To reheat, simply place the frozen crostini on a baking sheet and bake them at 350 degrees Fahrenheit until they are warmed through and crisp again. Do not thaw them before reheating, as this can turn the bread mushy rather than crunchy.
To save time on the day of your event, slice your baguette and mix your garlic-herb oil up to 24 hours in advance. You can store the bread in a sealed plastic bag and the oil in a small jar in the pantry. When guests are about to arrive, simply brush the oil, bake, and add the cheese. This preparation makes hosting feel effortless and keeps you out of the kitchen and enjoying the celebration.
Tips and Tricks
The most important tip for success is to use a high-quality loaf of bread. A fresh, crusty-on-the-outside and soft-on-the-inside French baguette provides the perfect foundation for your toppings, whereas pre-sliced grocery store bread often turns too hard or overly dry when baked. Always look for a loaf with a good structure that can handle being toasted without crumbling apart.
Do not be shy with the garlic, but be careful with the heat level if you are using a broiler. Garlic can turn bitter quickly if it burns, so monitor the oven closely during the final cheese-melting phase. If you notice your oven tends to run hot, keep the baking sheet on the middle rack rather than the top to ensure your crostini toast evenly without dark spots.
For the best flavor, use freshly grated parmesan cheese rather than the pre-grated kind found in canisters. Freshly grated cheese contains no anti-caking agents, meaning it will melt much smoother and provide a deeper, more authentic savory flavor that truly elevates the entire dish. It is a small effort that makes a massive difference in the final quality of your appetizer.

Chef’s Advice
To keep things interesting, try swapping the parmesan for Asiago or Pecorino Romano for a slightly sharper bite, or add a pinch of red chili flakes to the oil mixture if your guests enjoy a little bit of heat. For a truly professional presentation, arrange the crostini on a dark slate board and garnish with a sprig of fresh, bright green rosemary or thyme. The contrast between the golden-brown bread and the vibrant green herbs makes the dish look like it came straight from a gourmet kitchen.
How long do these stay crunchy?
These crostini stay crunchy for about two to three hours after baking if left at room temperature. For the absolute best texture, keep them shielded from humidity and serve them while they are still warm.
Can I make these gluten-free?
Yes, you can easily make this recipe gluten-free by using your favorite crusty gluten-free baguette. Just be sure to watch the baking time carefully, as some gluten-free breads crisp up much faster than traditional flour-based loaves.
What is the best way to prevent the garlic from burning?
The best way to prevent the garlic from burning is to keep the minced garlic pieces underneath the oil and inside the nooks of the bread. Using a lower rack position in the oven and keeping a close eye on the broiler stage will also protect your garlic from turning bitter.
Should I remove the crusts?
You definitely do not need to remove the crusts. The crust is actually the best part of a crostini, providing the structure and satisfying crunch that makes this appetizer so addictive.
Can I use dried herbs instead of fresh?
You can certainly use dried herbs if you do not have fresh on hand. Just remember to use smaller amounts, as dried herbs are more concentrated; substitute one teaspoon of dried parsley for every tablespoon of fresh.
