The magic of these croutons lies in their simplicity. By using quality sourdough bread—preferably a day or two old for the best texture—you create a sturdy base that absorbs the garlic-herb oil perfectly without becoming soggy. The air fryer's circulating heat ensures even browning and that satisfying crunch in every cube, while the combination of Italian herbs and fresh garlic creates an aromatic flavor that's both comforting and sophisticated. Whether scattered over a crisp green salad or floating atop a bowl of butternut squash soup, these croutons add texture, flavor, and a homemade touch that makes every meal feel special.

Ingredients

• 4 cups (about 200 g) sourdough bread, cut into 1-inch cubes (preferably day-old)
• 3 tbsp extra-virgin olive oil
• 2 cloves garlic, finely minced
• 1 tsp dried Italian herbs (basil, oregano, thyme, or a blend)
• ½ tsp sea salt
• ¼ tsp freshly ground black pepper
• 2 tbsp fresh parsley, finely chopped (optional, for garnish)

Instructions

Step 1: Preheat the Air Fryer

Preheat your air fryer to 375°F (190°C) for 2-3 minutes to ensure even cooking from the start.

Step 2: Prepare the Seasoning Mix

In a large mixing bowl, combine olive oil, minced garlic, dried herbs, salt, and pepper, stirring well to blend the flavors.

Step 3: Coat the Bread Cubes

Add the sourdough cubes to the bowl and toss until evenly coated with the oil and seasonings, ensuring every piece is well covered.

Step 4: Arrange in Air Fryer

Arrange the bread cubes in a single layer in the air fryer basket (cook in batches if necessary to avoid overcrowding).

Step 5: Air Fry to Golden Perfection

Air fry for 6–8 minutes, shaking the basket halfway through, until the croutons are golden and crisp.

Step 6: Finish and Cool

Transfer to a bowl and toss with fresh parsley if using. Allow to cool before serving or storing.

Zusatztipps für die Zubereitung

For the crispiest results, make sure your sourdough bread is at least one day old—fresh bread contains too much moisture and won't crisp up as well. Cut the cubes into uniform 1-inch pieces to ensure even cooking, and resist the temptation to overcrowd the air fryer basket. If you need to work in batches, keep the first batch warm in a low oven while finishing the rest. The halfway shake is crucial for even browning on all sides, so don't skip this step. If you find some cubes are browning faster than others, simply remove the golden ones and continue cooking the rest for another minute or two.

Varianten und Anpassungen

These croutons are wonderfully adaptable to your taste preferences and dietary needs. For a cheesy variation, toss the cubes with 2 tablespoons of grated Parmesan cheese before air frying for an extra savory kick. If you prefer a spicier version, add a pinch of red pepper flakes to the oil mixture. Swap the Italian herbs for other dried seasonings like rosemary and thyme for a more earthy flavor, or try everything bagel seasoning for a fun twist. For a garlic-free version, simply omit the garlic and increase the herbs slightly. You can also experiment with different types of bread—whole wheat, multigrain, or even gluten-free sourdough all work beautifully with this method.

Serviervorschläge

These versatile croutons shine in countless ways beyond the classic Caesar salad. Scatter them over roasted tomato soup, French onion soup, or creamy butternut squash bisque for added texture and flavor. Toss them into mixed green salads, grain bowls, or pasta salads for a satisfying crunch. They also make an excellent snack on their own—serve them in a bowl at parties or alongside cheese and charcuterie boards. For a unique appetizer, use them as a base for bruschetta toppings, or crush them lightly and use as a crunchy coating for baked chicken or fish. Store any leftovers in an airtight container for up to one week, though they're so delicious they rarely last that long.
