Gluten-free bread is expensive. Don’t throw away the ends, the imperfect loaves, or the slices nobody finished—turn them into breadcrumbs.
The Story
When I was learning to make GF sourdough, I had a stretch of loaves that weren’t quite right. The crumb was too dense, the rise was off, the crust went weird—the kind of loaves you can’t in good conscience put in a sandwich but also cannot bring yourself to throw away because you know exactly how much that bag of GF flour cost.
Breadcrumbs were the answer. Those imperfect loaves got a second life, and honestly, the breadcrumbs didn’t care about the crumb structure at all.
Now that GF sourdough is more reliable, breadcrumbs have become my go-to for the ends of loaves and anything that’s getting stale before we finish it. GF bread dries out faster than wheat bread anyway—which turns out to be a feature when you’re making breadcrumbs.
I thought about croutons too, but we use breadcrumbs constantly and croutons only occasionally. Breadcrumbs made more sense for how we actually cook.
What to Use
Any GF bread works—homemade or store-bought:
- Ends of the loaf — we always have these and they’re never the first choice for sandwiches
- Stale slices — GF bread goes stale fast; this is the solution
- Imperfect loaves — dense, flat, over-proofed, under-proofed, whatever went wrong; it doesn’t matter for breadcrumbs
- Leftover dinner rolls or biscuits — same idea
Store-bought GF bread is just as expensive as homemade, so the same logic applies—don’t throw away the ends or the bag that’s going stale.
I don’t mix GF bread with regular bread since we need to keep things gluten-free, but you can use any combination of GF breads together. Different breads, different flavors—it all works.
The Method
Step 1: Collect and Dry the Bread
If you’re not ready to make a batch yet, toss bread pieces into a zip-lock bag in the freezer as they accumulate—ends, stale slices, imperfect loaves. When the bag is full, you’re ready to make breadcrumbs. This also means nothing goes to waste in the meantime.
When you’re ready to process, cut the bread into rough cubes—this helps them dry evenly and fit better in the food processor later. Spread in a single layer on a baking sheet. You have two options:
Oven method: Bake at 250°F or lower, flipping occasionally, until completely dry and hard throughout—test by breaking a piece; it should snap cleanly. Don’t be tempted to crank up the heat to speed things up; low and slow is what dries the bread without browning it. Time varies a lot depending on your bread. A store-bought loaf or a lighter homemade bread might be done in 20–30 minutes. A dense, moist sourdough can take quite a bit longer. Go by feel, not the clock.
Dehydrator method: Spread cubes on dehydrator trays and run until fully dry and brittle. Time varies by dehydrator and how dense the bread is—check after a few hours. Great option if your oven is busy or you’re already running the dehydrator for something else.
Air-dry method: Leave the bread out on the counter overnight (or a few days if you’re not in a hurry). GF bread dries out on its own pretty fast. Once it’s rock hard, you’re ready to process it.
Step 2: Condition the Dried Cubes
Before processing, let the dried cubes cool completely—sealing warm bread in a jar will cause condensation and trap moisture you just worked to remove. Once fully cool, store the cubes loosely in an airtight jar for at least a week, rotating the jar daily to move the cubes around. This conditioning step is how you catch any remaining moisture—if the pieces soften or you see condensation on the jar, they go back in the dehydrator or oven. Better to find out now than to end up with moldy breadcrumbs after they’re already ground and stored.
Step 3: Process into Crumbs
Once the bread is fully dry, pulse it in a food processor until you get the texture you want. A few pulses gives you coarser crumbs. More processing gives you fine crumbs.
No food processor? Put the dried bread in a zip-lock bag and roll over it with a rolling pin. Takes a little more elbow grease but works fine.
Step 4: Store
My preference is quart or half-gallon canning jars with vacuum-sealed lids. After filling, I vacuum seal the lid—and reseal it after every use. It keeps moisture out and extends shelf life significantly without needing the freezer.
A regular airtight container works too, but the vacuum seal gives you real peace of mind after putting in the work to dry and condition the bread properly.
How I Use Them
GF breadcrumbs work anywhere regular breadcrumbs do:
Breading: Coat chicken, pork chops, or fish before pan-frying or baking. Add your seasonings to the crumbs before coating.
Meatballs and meatloaf: GF breadcrumbs are actually what most of our meatball recipes use anyway. This just means we’re making our own instead of buying a box.
Casserole and hotdish toppings: Toss with a little butter or olive oil and sprinkle on top before baking for a crispy crust.
Stuffed vegetables: Mixed with seasoning, cheese, and herbs for stuffed mushrooms, peppers, or zucchini.
Pasta and soups: A spoonful of toasted breadcrumbs adds texture as a garnish—the Italian trick of using breadcrumbs as a budget version of Parmesan.
Seasoned vs. Plain
I usually make plain breadcrumbs and season them when I use them. That way one batch works for everything.
If you want seasoned breadcrumbs, add to the food processor while processing:
- Italian-style: dried oregano, basil, garlic powder, salt
- Garlic Parmesan: garlic powder, Parmesan, salt, pepper
- Whatever your recipe calls for
Seasoned breadcrumbs don’t keep as long, so I only make them for a specific recipe.
The Sustainability Win
GF bread is expensive—easily two to three times the cost of regular bread. Throwing away the ends or a whole imperfect loaf is a real loss, not just a little kitchen waste.
What you’re saving:
- The cost of the bread (GF ingredients add up fast)
- The cost of store-bought GF breadcrumbs, which are also not cheap
- The packaging waste from boxed breadcrumbs
What you get:
- A pantry staple ready when you need it
- Breadcrumbs made from bread you already know is safe (no cross-contamination concerns)
- A way to use loaves that didn’t turn out—especially important when you’re still learning a new bread
This is the same philosophy as saving bones for broth or turning tomato skins into powder: the parts that feel like failures or leftovers still have value. You just have to capture it.
Tips from Our Kitchen
- Don’t skip the conditioning week. It’s the only way to know the bread is truly dry before you grind it. Moldy breadcrumbs are a frustrating loss—the conditioning step prevents it.
- Reseal after every use. If you’re using vacuum-sealed jars, take the 10 seconds to reseal the lid each time. You’ve already done the work to get the moisture out—don’t let it back in.
- Don’t overthink the texture. A mix of fine and coarser crumbs works well in most recipes. You don’t need to be precise.
- Label your containers. If you make a seasoned batch, label it—plain and Italian-seasoned look identical in a jar.

GF bread that didn’t rise right is still bread. Bread that’s going stale is still food. Turn it into breadcrumbs and it’s useful for months.
