Leftover hamburger buns can be turned into croutons, breadcrumbs, French toast cups, garlic bread, panzanella, strata, or bread pudding, saving up to $4.50 per week compared to buying store-bought equivalents.
You bought a 12-pack of hamburger buns for the cookout. You used seven. The other five are sitting on the counter slowly getting hard, losing flavor, and one might even have a small colony of mold forming. Here’s what to actually do with them, and none of these answers are “make another burger.”

If you’re staring down leftover hamburger buns, you’ve got at least seven solid moves: croutons, breadcrumbs, garlic bread, French toast cups, panzanella, strata, or bread pudding. Most take under 20 minutes. All of them beat the trash.
In this post:
- Homemade croutons from leftover hamburger buns cost approximately $0.15 per serving versus $0.60 for store-bought, saving families around $4.50 per week across three salads.
- Individual French toast cups made from 3 hamburger buns, 3 eggs, and 3 tablespoons of milk bake in 15 minutes at 400°F and feed 6 people for $1.20 total.
- Homemade breadcrumbs from torn hamburger buns cost $0.08 per ounce versus $0.25 for store-bought, making them one of the cheapest pantry swaps available.
- Stale hamburger buns work better than fresh for strata and panzanella, drier bread absorbs egg mixtures and dressings without turning to mush.
- Bread pudding, historically a staple for using stale bread, requires 2 cups of cubed buns per batch and costs under $2 to make.
What to Do With Leftover Hamburger Buns: The Savory Side
Croutons. Cut four day-old buns into cubes, toss with a quarter cup of olive oil and whatever seasoning is in arm’s reach, and bake at 350°F for 25 minutes. Per Tastes of Homemade, that comes out to about $0.15 per serving versus $0.60 for the bagged kind, a $4.50 weekly difference if you’re making three salads. Keeps two weeks in an airtight container. No more paying for croutons.
Breadcrumbs. Tear two or three buns, pulse them in a food processor (or just bash them in a zip-lock bag, if you want to blow off some steam), and toast. Simply Recipes puts the cost at $0.08 per ounce versus $0.25 store-bought. Use them for breading chicken, topping a baked pasta, or anywhere the box of Panko would have gone.
Garlic bread. Smear butter, garlic, and parsley between the bun halves. Bake at 350°F for 10 minutes. Four servings at $0.40 each. This is also the correct answer to “what do I serve with the leftover burger skillet hash I made from last night’s cookout”, which, if you haven’t tried, is worth a look.

Panzanella. Cube the stale buns, let them sit out until properly dry (fresh bread goes soggy fast, stale is actually the goal here), and toss with tomatoes, olive oil, and basil. Taste of Home puts this at a $2.50 side dish for four. It sounds fancy and takes ten minutes.
The Breakfast and Dessert Side

French toast cups. Three buns, three eggs, three tablespoons of milk, a splash of vanilla, a shake of cinnamon. Press the bun pieces into a muffin tin and bake at 400°F for 15 minutes. Per Betsy Life, that’s six servings for $1.20 total. Reheat in 30 seconds. This is genuinely what you want to have as your grab and go breakfast before taking off to work..
Strata. Eight cups of cubed stale buns, eggs, cheese, whatever vegetables need rescuing from the produce drawer (Pantidy’s expiring-items view is useful here, it shows what needs to go first). Assemble the night before, bake at 390°F for 33 minutes in the morning. Pamela Salzman’s version costs about $2.50 for four servings. Drying the buns overnight is the move, it cuts cooking time and keeps the texture from going gluey.
Bread pudding. Two cups of cubed buns, a custard mixture, baked low and slow. It was reportedly Princess Diana’s favorite dessert (not a fact we expected to be writing today, and yet). Stale buns absorb the custard better than fresh, which means the thing you were about to throw out is actually the correct ingredient.

Frequently Asked Questions
What can I do with leftover hamburger buns besides burgers?
Leftover hamburger buns work well as croutons, breadcrumbs, garlic bread, French toast cups, panzanella, strata, or bread pudding. Simply Recipes and Taste of Home both cover the full range. Most uses actually benefit from slightly stale buns, so don’t rush.
How do I make croutons from leftover hamburger buns?
Cut the buns into cubes, toss with olive oil and seasoning, and bake at 350°F for about 25 minutes until golden. Tastes of Homemade puts the cost at around $0.15 per serving, about a quarter of what bagged croutons cost. Store them in an airtight container and they’ll keep for two weeks.
Can you freeze leftover hamburger buns?
Yes. Wrap them individually or in pairs and freeze before they go stale, not after. They’ll keep for up to three months and thaw in about 20 minutes at room temperature, or faster in a low oven. Pantidy is a pantry and freezer tracking app that can log your frozen buns with an expiration reminder so you don’t forget they’re in there.
Are stale hamburger buns better for some recipes?
Yes, for strata, panzanella, and bread pudding, stale bread is actually preferable. Simply Recipes notes that drying buns overnight or toasting them in a low oven before using in strata reduces cooking time and prevents a soggy texture. Fresh buns absorb liquid too fast and turn mushy, per Simply Recipes.
How much money can I save by using leftover hamburger buns instead of buying store-bought alternatives?
Switching to homemade croutons alone saves about $4.50 per week across three salads, according to Tastes of Homemade. Homemade breadcrumbs from leftover buns run $0.08 per ounce versus $0.25 for store-bought, per Simply Recipes. Over a month, those two swaps alone add up to real money.
Can I make strata with leftover hamburger buns?
Yes. Cube 8 cups of stale buns, combine with eggs, cheese, and whatever vegetables are about to go, and assemble the night before. Bake at 390°F for 33 minutes in the morning. Pamela Salzman’s version costs about $2.50 for four servings.
