Ingredients

• Bread: 4 cups (about 200 g) sourdough bread, cut into 1-inch cubes (preferably day-old)
• Flavorings: 3 tbsp olive oil or unsalted melted butter
• 1 garlic clove, minced
• 1/2 tsp sea salt
• 1/4 tsp freshly ground black pepper
• 1/4 tsp dried thyme or herbes de Provence (optional)
• 1/2 cup (50 g) grated Gruyère or Emmental cheese (optional)

Instructions

Step 1

Preheat your oven to 375°F (190°C) and line a baking sheet with parchment paper.

Step 2

In a large bowl, combine the olive oil or melted butter, minced garlic, salt, pepper, and herbs if using.

Step 3

Add the sourdough cubes to the bowl and toss well until every piece is evenly coated.

Step 4

Spread the bread cubes in a single layer on the prepared baking sheet.

Step 5

Bake for 15–18 minutes, stirring once halfway through, until they are golden and crisp.

Step 6

If using cheese, sprinkle the grated Gruyère over the hot croutons and return to the oven for 2–3 minutes until melted and bubbly.

Step 7

Let the croutons cool slightly before using them as a topper for your soup.

Zusatztipps für die Zubereitung

For an even deeper garlic flavor, rub the cut bread with a halved garlic clove before cubing it. Using day-old bread is ideal because its lower moisture content allows it to crisp up more efficiently in the oven.

Varianten und Anpassungen

You can easily swap Gruyère for other cheeses like Comté or Swiss cheese to vary the flavor. To make this recipe dairy-free, simply use olive oil and omit the optional cheese garnish.

Serviervorschläge
