If you have leftover bread sitting on the counter, please do not throw it away. You can turn it into the most gorgeous homemade breadcrumbs in just a few minutes, and honestly, it is so much better than paying for the tiny pre-made tubs at the store. Bread is one of the most wasted foods in the world, with more than 900,000 tonnes tossed every year, which is wild when you think about how easy it is to give it a second life.
All you need is leftover bread and a little oil. Process, bake, et voilà, you have fresh, super-tasty breadcrumbs that cost basically nothing. They store well, they taste better, and you get that satisfying feeling of not letting good food go to waste. This is the kind of simple kitchen habit I love because it saves money, reduces waste, and makes your cooking even better.
I love to use wholemeal sourdough bread for this recipe. Sourdough is one of those little nutrition wins I adore because the long fermentation does so much of the work for you. It breaks down some of the gluten and starches, so it is easier on your stomach. It also has a gentler effect on your blood sugar, which helps keep your energy steadier. The fermentation lowers phytic acid, too, so your body can absorb more of the minerals already in the flour.
Why I love this recipe (as a nutritionist)
- Perfect for reducing food waste: an easy way to use leftover bread instead of throwing it out
- Budget-friendly pantry staple: homemade breadcrumbs are far more affordable than packaged ones
- Beautiful texture: adds crunch and contrast to dishes without relying on ultra-processed options
- Customizable flavor: keep them neutral or add garlic powder, herbs, or chili flakes
- Minimal ingredients: only bread and olive oil
Ingredient notes
- Sourdough bread: brings a deeper flavor compared to regular sandwich bread and crisps beautifully; use any leftover slices you have
- Olive oil: helps the crumbs toast evenly and turn golden; you can swap with avocado oil if preferred
- Infused oils: chili, garlic, or truffle oil can elevate the flavor depending on what dish you plan to use the crumbs for
