📝 About This Recipe
Originating from the rustic kitchens of Italy, these 'little crusts' are the quintessential canvas for any gourmet appetizer. By using the air fryer, we achieve a superior, uniform crunch and a deep golden hue that traditional ovens often struggle to replicate in such a short time. Infused with aromatic garlic and a bouquet of fresh Mediterranean herbs, these crostini are light, incredibly crisp, and far more flavorful than any store-bought alternative.
🥗 Ingredients
The Bread
- 1 loaf French Baguette (slightly stale bread works best for maximum crunch)
Infused Herb Oil
- 1/3 cup Extra Virgin Olive Oil (high quality, cold-pressed)
- 2 cloves Garlic (finely minced or pressed)
- 1 teaspoon Fresh Rosemary (minced very finely)
- 1 teaspoon Fresh Thyme (leaves stripped from the stem)
- 1/2 teaspoon Dried Oregano
- 1/4 teaspoon Smoked Paprika (for a subtle warmth and color)
Seasoning & Finish
- 1/4 cup Parmesan Cheese (finely grated, optional)
- 1/2 teaspoon Flaky Sea Salt (Maldon or similar)
- 1/4 teaspoon Black Pepper (freshly cracked)
- 1 tablespoon Fresh Parsley (chopped for garnish)
👨🍳 Instructions
-
1
Place the baguette on a sturdy cutting board. Using a sharp serrated knife, slice the bread on a slight diagonal into 1/2-inch thick rounds. The diagonal cut (bias) provides more surface area for toppings.
-
2
In a small microwave-safe bowl or small saucepan, combine the extra virgin olive oil and the minced garlic.
-
3
Gently warm the oil and garlic over low heat for 2 minutes, or microwave for 20 seconds. This releases the garlic's essential oils without browning it.
-
4
Whisk the minced rosemary, thyme, dried oregano, and smoked paprika into the warm oil. Let it steep for 5 minutes to infuse the flavors.
-
5
Preheat your air fryer to 350°F (175°C) for about 3 minutes to ensure an even cooking environment.
-
6
Using a pastry brush, lightly coat both sides of each bread slice with the infused herb oil. Ensure even coverage but do not soak the bread.
-
7
Arrange the bread slices in a single layer in the air fryer basket. Work in batches if necessary to avoid overlapping, which prevents even crisping.
-
8
If using, sprinkle a tiny pinch of finely grated Parmesan cheese over the top of each slice before air frying.
-
9
Air fry at 350°F for 4 to 6 minutes. At the 3-minute mark, open the basket and flip the slices using tongs to ensure uniform browning.
-
10
Check for a deep golden-brown color and a firm, toasted texture. They will continue to crisp up slightly as they cool.
-
11
Immediately upon removing from the air fryer, sprinkle with flaky sea salt and freshly cracked black pepper while the oil is still warm.
-
12
Transfer the crostini to a wire cooling rack to prevent the bottoms from becoming soggy due to steam.
-
13
Garnish with a sprinkle of fresh parsley and serve warm or at room temperature with your favorite toppings.
💡 Chef's Tips
For the best texture, use a baguette that is 1-2 days old as the lower moisture content results in a crunchier bite. If you find the garlic bits are burning in the air fryer, strain the oil through a fine-mesh sieve before brushing it onto the bread. To make these vegan, simply omit the Parmesan cheese; the herb oil provides plenty of savory depth on its own. Avoid slicing the bread too thin (less than 1/4 inch) as they can blow around in the air fryer and burn quickly. Store leftover un-topped crostini in an airtight container for up to 3 days; re-crisp in the air fryer for 1 minute before serving.
🍽️ Serving Suggestions
Top with classic tomato and basil bruschetta mix for a timeless Italian appetizer. Spread with creamy goat cheese and a drizzle of honey for a sweet and savory contrast. Serve alongside a charcuterie board featuring prosciutto, olives, and sharp provolone. Pair with a crisp glass of Pinot Grigio or a chilled Prosecco to balance the salty, herbal notes. Use as a crunchy accompaniment to a hot bowl of French Onion soup or creamy tomato bisque.
