One of the most versatile uses for leftover buns is turning them into breadcrumbs or croutons. Both are incredibly useful for adding texture and flavor to various dishes.

To make breadcrumbs, simply tear the buns into pieces and pulse them in a food processor until you reach your desired consistency. Spread the crumbs on a baking sheet and toast in the oven at 300°F (150°C) for about 10-15 minutes, or until golden brown. Store your homemade breadcrumbs in an airtight container in the freezer for up to three months.

Croutons are an easy way to elevate salads, soups, and even pasta dishes. To make croutons, cut the buns into cubes, toss them in olive oil, salt, and your choice of seasonings (garlic powder, Italian herbs, or paprika work well), and spread them on a baking sheet. Bake at 375°F (190°C) for about 15-20 minutes, or until crispy and golden.

For a more indulgent treat, try making cheesy garlic croutons. Mix cubed bun pieces with melted butter, minced garlic, and grated Parmesan cheese. Spread the mixture on a baking sheet and bake at 350°F (180°C) for about 15-20 minutes, or until the croutons are golden and crispy.

Bunwiches

A bunwich is essentially a sandwich made with a bun instead of bread. The possibilities are endless – from classic BLTs to pulled pork, chicken Caesar, or even veggie-filled creations. To keep your bunwich from getting soggy, make sure to toast the bun lightly and add any saucy or wet ingredients just before serving.
