To make breadcrumbs, simply tear the buns into pieces, pulse them in a food processor until you have coarse crumbs, then spread them on a baking sheet and toast in the oven at 300°F (150°C) for about 10 minutes or until golden. For croutons, cut the buns into cubes, toss in olive oil, salt, and your choice of seasonings, then bake at 375°F (190°C) for 15-20 minutes.

Old hamburger buns are an excellent addition to meatballs and meatloaf recipes. They help to bind the ingredients and keep the dish moist. To incorporate them, soak the buns in milk or water, then squeeze out the excess liquid and mix them into your meat mixture.

For example, try this classic Meatloaf recipe: Combine 1 lb (450g) ground beef, 1 small onion (finely chopped), 1 clove garlic (minced), 1/2 cup (120ml) ketchup, 1/2 cup (120ml) milk, 1/2 cup (50g) breadcrumbs (made from your old buns), 1 egg, salt, and pepper. Form the mixture into a loaf, place it on a baking sheet, and bake at 350°F (180°C) for about 1 hour.

French Toast and Bread Pudding

Stale buns are perfect for French toast and bread pudding, as they absorb the custard mixture beautifully. For French toast, dip slices of bun in an egg and milk mixture, then cook in a buttered skillet over medium heat until golden brown. For bread pudding, tear the buns into pieces, combine them with a custard mixture (milk, eggs, sugar, and vanilla), let it soak for a few hours, then bake at 350°F (180°C) for about 45 minutes.

Try this indulgent Bread Pudding recipe: Combine 6 cups (1.4L) milk, 1 cup (200g) sugar, 4 eggs, 1 tsp vanilla extract, and a pinch of salt. Pour this mixture over 6 cups (1.4L) of torn buns in a greased baking dish. Let it soak for 1 hour, then bake as described above. Top with caramel sauce or whipped cream for an extra treat.
