These quick 5-minute Uncrustable sandwiches are a copycat version of the store-bought favorite, made with simple ingredients and a clever jar trick for perfect sealing. They’re budget-friendly, customizable, and perfect for school lunches.
For best results, use room temperature bread. Don’t overfill the sandwiches—2 tablespoons each of peanut butter and jelly is the sweet spot. Work quickly to prevent the bread from drying out. The sandwiches actually taste better after freezing as the flavors meld together.
