Sourdough Bread Crumbs From Scratch

Sourdough bread crumbs add texture and crunch, making dishes even more delicious. Rather than buying pre-packaged bread crumbs, make your own at home with old sourdough bread. When you have an older loaf sitting in the breadbox or no one is eating the end slices, use them for bread crumbs!

They have a unique flavor that adds the perfect zest to any dish. I love using homemade crumbs to make hand-breaded chicken strips and to top cheesy potato casserole. Let’s dive in!

Type of Bread for Bread Crumbs

You can essentially use any type of sourdough bread but the best is older loaves or ends. You’ll want the moisture level to be pretty low so it’s easier to make the bread crumbs. Fresh sourdough loaves usually have a good amount of moisture but if you’re in a pinch you can make it work!

That’s how this recipe blossomed, we had half of a loaf starting to get super dry in our bread box and the ends of another loaf sitting around. I didn’t want to waste them but we weren’t eating it up. I knew I needed to figure something out and if you know me personally, I like to get creative. After taking inventory of the fridge, freezer, and pantry I thought, “Breaded Nashville hot chicken sounds wonderful for supper but we don’t have anything for the breading.” That’s when I decided to try a batch of homemade bread crumbs. After a few tries, I created the perfect recipe and that’s why we’re here!

Important Things To Know

How Large To Cute Bread?

When prepping your bread, you’ll want to cut the pieces into cubes. This allows even toasting in the oven which dries the bread out so much quicker. Also, it’ll be easier to blend the pieces in your food processor. My first take on testing for this recipe was a disaster. I didn’t cut the pieces small enough which ended up causing issues with our food processor. You live and you learn haha!

What’s the Best Bread Crumb Storage?

After making your bread crumbs, it’s important to store them correctly so they stay fresh. If you plan to use them within a day or two, store in a glass, airtight container. If you don’t know when you’ll use them, store in a glass, airtight container in your freezer. It’ll keep them fresh for up to three months.

What Can You Use Bread Crumbs For?

There are tons and tons of recipes you can make for using up bread crumbs. If you’re looking for a savory entrée try hand-breaded chicken strips, crab cakes, and oven-baked parmesan-crusted fish. If you’re looking for a side dish or appetizer try crumb-topped macaroni and cheese, and jalapeno popper Mexican street corn.

Servings 1 Depends on Bread Amount


  • 1 Bread Knife
  • 1 Baking Sheet
  • 1 Oven
  • 1 Food Processor


  • 1-10 slices Sourdough Bread (use what you have amount doesn't matter)


  • First preheat oven to 250 degrees Fahrenheit. Then cut your sourdough bread that you'll be using into 1-2 inch cubes and place them on a baking sheet.
  • Next place the baking sheet full of bread cubes into the preheated oven for 40-50 minutes or until bread feels dry and hard.
  • Then take them out of oven and let cool for about 30 minutes. Finally add them to a food processor and pulse until all bread has turned into crumbs. Pour into your storage container and enjoy!


Food Processor – pulse only to prevent bread crumbs turning into dust
Texture – If you like your bread crumbs larger, pulse less. If you like them small and tiny pulse more.
