It’s hard to argue that soups and salads are made IMMEDIATELY better with some crunchy croutons, am I right?! If you’ve ever wondered how to make croutons at home, I’m here to show you just how simple it is!

As a dietitian, sourdough is one of my favourite breads out there. I love buying a fresh loaf from local bakeries as they usually are made from very simple ingredients (just a sourdough culture, flour, and salt).

An added bonus? Many people find sourdough easy to digest and it actually provides a handful of nutrition benefits (more details below!)

Making croutons from sourdough bread is SO easy and you can store them for about a week to add to soups or salads, as desired (I’ve included a bunch of serving ideas for you below).

It’s also a great way to use up old sourdough bread and prevent food waste – always a win! Enjoy 🙂

All You Need Are 3 Ingredients!

Here’s what you need to make these sourdough croutons:

  • sourdough bread (I love finding one from a local bakery, as I find they have the best ingredients and quality)
  • olive oil
  • salt

Full ingredient measurements and detailed instructions are located in the recipe card at the bottom of this post!

Optional Extra Seasonings

While I love to keep this recipe simple so that it pairs with everything, you can also add some extra seasonings to your croutons if preferred. Ones that would work well include:

How To Store Croutons

Homemade croutons will keep up to 1 week in an airtight container, although they are best the first couple days!

You do not need to store croutons in the fridge – they keep best in a cool, dry place at room temperature.

Sourdough Nutrition Facts

Sourdough bread is made through the process of fermentation. The leavening process of sourdough is done through a mix of wild yeast and lactic acid bacteria, rather than baker’s yeast.

Because it’s fermented with lactic acid bacteria, sourdough will have lower levels of phytates. This means that your body may be better to absorb the nutrients present in the bread!

What nutrients are in sourdough? While the nutrition profile will vary depending on the type of flour used, sourdough can be a good source of nutrients like:

  • carbohydrates
  • protein
  • fibre
  • selenium
  • folate
  • thiamin
  • niacin
  • manganese
  • iron

Research has also shown that the sourdough fermentation process may degrade gluten better than baker’s yeast. Some gluten-sensitive individuals may find that they can tolerate sourdough more so than other breads.

For the same reason, 2 slices of sourdough are also considered low FODMAP!

Please note, of course, that gluten tolerance is very individual and sourdough will likely not be suitable if you have celiac disease.
