🛒 What You'll Need
- Sourdough Bread - stale leftover sourdough bread works really well. If you don't have sourdough don't worry you can still make these, in fact, most leftover bread will work. The only exceptions are sliced bread loaves and soda bread.
- Oil - lightly flavoured olive oil is best here. You can use infused oils if you have them, garlic infused oil works really well.
- Salt - flaky sea salt, such as Maldon sea salt flakes works really well.
- Garlic - this is optional but highly recommended! If you don't have fresh garlic you could use garlic powder instead. You won't need much, a pinch or two should do. You can add other herbs too if you have them, fresh thyme works lovely.
🔪 How To Make Sourdough Croutons
This is just a quick visual guide, please see the recipe card below for full instructions.
- Use a serrated knife or bread knife to slice the bread, brush the slices of sourdough bread with oil place the bread on a sheet pan or rimmed baking sheet and pop it in the oven for a few minutes.
- Take the tray out of the oven then rub each side of the bread with garlic.
- Cut the bread into cubes, add the sourdough bread cubes to a large bowl, toss in oil add some sea salt. Place them on a baking sheet in a single layer, then pop them back in the oven and cook until golden.
👩🍳 Recipe Tips and Variations
- Bread - we love sourdough for making croutons but most bread will work well, wholemeal, and granary work very well too. The trick is to use stale bread and make sure it is sliced thickly. You can leave the crust on or off, it's up to you. I prefer the crust left on when it comes to sourdough.
- Bake or fry? - I prefer to bake these, but you can fry them too. You will need to fry them in batches if you fry them and toss them often so that they are golden on all sides.
- Oils - you should be aware that any oil you use to make these croutons will be absorbed by the bread so the finished croutons will take on that flavour. I find that mild, lighter-flavoured olive oil works really well. Rapeseed oil works well too. You could also try avocado oil if you like.
- Extras - the world is your lobster here! You can add dried herbs, fresh herbs, and onion powder is great. Freshly grated black pepper adds a little heat and is a nice variation. Grated cheese works well too, try vegetarian parmesan cheese for an extra cheesy crouton.
Well, they can last for up to a week. Once cooled transfer any leftover croutons
to a sealed bag or airtight container. Keep them at room temperature. I keep them on the counter. That said, every single time I make these they do not last longer than 2 days, they are very snackable!
Yes! You can freeze these croutons. Once cooled put them in a freezer bag, make sure to get as much air out of the bag as possible before you seal it then freeze for up to a month. The great thing about croutons is that they thaw really quickly so take them out of the freezer a couple of hours before you use them. You can refresh them in a preheated oven if you like.
No, any kind of bread will work except for sliced sandwich bread, this bread is generally too thin to make croutons with.

- Bread - slightly stale sourdough is best for this recipe, however, any bread will work except for sandwich bread which is usually thinly sliced.
- Want more garlic - if you want more of a garlic flavour to these then I would use garlic-infused oil. You can make your own by adding 1 very finely grated clove of garlic to the oil a good few hours before you make the croutons.
- Herbs - if you want to add herbs to these then for dried herbs, add them to the croutons when you add the salt. For fresh herbs, I would add them towards the end of cooking, so add them at the last 5 minutes and toss well.
- Storing - Once cooled transfer them to a sealed bag or airtight container. Keep them on the counter.
- Freezing croutons - Once cooled put them in a freezer bag, make sure to get as much air out of the bag as possible before you seal it then freeze for up to a month.
