Ingredient breakdown: key components
- Baguette slices: I like mine not too thin, around 1/2 inch, for that perfect crunch. Skip thin slices or they’ll burn before crisping up.
- Garlic: Fresh, minced garlic gives a fragrant punch that fills the kitchen. Use garlic powder if pressed for time, but it’s not quite the same aroma.
- Olive oil: Drizzled generously, it turns the crostini golden and adds a fruity richness. Use a good quality extra virgin for best flavor.
- Herbs: Fresh thyme or rosemary make a bright, aromatic layer. Dried herbs work in a pinch but lose some punch and vibrancy.
- Salt & pepper: A pinch of flaky sea salt and freshly cracked pepper finish off the flavor. Adjust to taste—less salt if serving with salty toppings.
- Optional toppings: Cheeses, roasted vegetables, or a smear of tapenade—these elevate the base. Think about balancing textures and flavors for your mood.

Ingredients
Equipment
Method
- Preheat your oven to 180°C (356°F). Using a serrated knife, slice the baguette into 1/2-inch thick pieces, aiming for even slices that will toast uniformly.
- Place the slices flat on a baking sheet, spacing them apart to allow for even baking and crisping.
- In a small bowl, mix the olive oil with the minced garlic and a pinch of salt. Use a pastry brush to generously coat each slice with this fragrant oil mixture, ensuring every piece is well-coated for flavor and crispness.
- If you like, sprinkle chopped fresh herbs like thyme or rosemary over the coated slices to add an aromatic, herbal touch.
- Bake the crostini in the preheated oven for 10-12 minutes, or until they are golden brown and crisply fragrant. Keep an eye on them around the 10-minute mark to prevent burning.
- Once baked, remove the crostini from the oven and transfer to a wire rack to cool slightly, about 2 minutes. This helps them stay crisp and prevents sogginess.
- Finish by sprinkling with flaky sea salt and freshly cracked black pepper to taste, enhancing the flavor and adding a touch of sparkle.
- Serve the crostini warm or at room temperature, either plain or topped with your favorite spreads, cheeses, or vegetables for a customizable snack or appetizer.
Pro tips for perfect crostini
- Pre-toast the bread: Lightly toast slices for 2 minutes before oiling to prevent sogginess.
- Use a garlic-infused oil: Let minced garlic sit in olive oil for 10 minutes to deepen flavor before brushing on.
- Apply oil generously: Don’t skimp—rich coating ensures maximum crunch and golden color.
- Watch oven carefully: Crostini can go from golden to burnt in seconds—keep an eye around 10 minutes mark.
- Cool on a rack: Transfer baked crostini to a wire rack immediately for crispness that lasts.
- Add herbs at the right time: Sprinkle fresh herbs in the last 2 minutes of baking for vibrant aroma and flavor.
- Serve slightly warm: Crostini taste best when still warm—reheat at 150°C (300°F) if needed, just until fragrant.
Common mistakes and how to fix them
- FORGOT to watch oven temp → Over-browning or under-crisping, adjust heat accordingly.
- DUMPED the garlic oil → Burnt garlic flavor; brush on oil in thin layers for even coating.
- OVER-TORCHED the crostini → Rinse under cold water, start over with lower oven temperature.
- MISSED the resting step → Crostini may be floppy; let cool for crunch and flavor to settle.
Kitchen quick fixes
- When crostini are too soft, splash with a light mist of water and bake 2 minutes longer.
- If bread burns quickly, patch with a quick sprinkle of fresh herbs and lower oven temp.
- Over-oiled slices shimmer and crackle—reduce oil and brush more evenly for a balanced crunch.
- Forgot to preheat? DUMP the cold sheet, warm it in the oven first, then re-bake for even crispness.
- When in doubt, pantry swap: use toasted pita or thick crackers for a quick fix with similar texture.
Prep, store, and reheat tips
- Prep the crostini slices a day ahead; store in an airtight container at room temperature to keep crisp without becoming stale.
- Refrigerate any toppings or spreads separately if you plan to assemble just before serving; they stay fresh for up to 2 days.
- Store baked crostini in an airtight container for up to 2 days; reheat in a 150°C (300°F) oven until fragrant and crispy again, about 5 minutes.
- For best sensory results, avoid stacking or sealing warm crostini, which can cause sogginess during storage.
