These easy freezer lunchbox uncrustables are a homemade version of the classic frozen sandwich, perfect for busy mornings and after-school snacks. Made with simple ingredients and a foolproof technique, they’re cost-effective, customizable, and taste fresh even after freezing.
Use soft sandwich bread for best results; avoid dense or crusty breads. Processed peanut butter works better than natural for freezing. Leave a ½-inch border when spreading fillings to prevent leakage. Freeze sandwiches flat for even thawing. Sandwiches stay good in the freezer for up to 3 months. Do not microwave to thaw.
