Cube your bread. If you're not fussed by them then leave the crusts on to save time/cut waste.
Melt together your butter and olive oil. Drizzle over the cubed bread.
Sprinkle on your choice of herbs/seasonings. I like garlic, salt & pepper and basil.
If you want to save time/effort then brush the bread before you cube it.
To make your homemade croutons a little healthier then use brown or seeded bread and use spray oil instead.
Bake in the oven at gas mark 4 (180c) for 15-17 minutes. They are cooked once lightly browned.
