Melt the butter over a gentle heat, mix in the bread. Spread on a baking sheet (lined with baking paper). Bake in a preheated oven at 150 ° C (convection: 125 ° C) until golden brown (takes approx. 15 min.)
If you want, you can also use garlic or herb butter, then the baking time is approx. 5 minutes shorter.
The amount is enough as a soup or on a salad for 4 people.
