Sausage biscuits are among the many breakfast convenience foods in the grocery store's freezer aisle. And like most boxed, frozen breakfast foods, you can easily make them yourself at a fraction of the cost. Make several sausage biscuits at once and freeze them for an easy meal that less than a minute in the microwave. A sausage biscuit requires only two components: a biscuit split in half and a sausage patty. You can bake the biscuits from scratch or use canned biscuits and pre-formed sausage patties to cut down on preparation time, but even these time-saving products save money.
Bake the biscuits and allow them to cool completely. Form the sausage into patties slightly larger in diameter than the biscuits and pan-fry them until they're cooked thoroughly. Because the sausages shrink when you cook them, it's best to make them slightly larger to account for this.
Split or cut the biscuits into halves and place them open side up on a baking tray lined with parchment paper. Lay each sausage piece on a separate tray lined with parchment paper.
Place the trays in the freezer and freeze the sausage and biscuit halves separately for about three hours or until frozen. Remove the trays from the freezer. The biscuits and sausage don't need to be frozen completely through, but the outsides should at least be frozen. Separate trays keep the biscuits and sausage from freezing as a single unit and allows each piece to freeze rapidly. This reduces the condensation that leads to ice crystals that can make the reheated sandwich soggy.
Assemble the sandwiches so you have a sausage patty in between the two biscuit halves.
Wrap each sandwich individually with clear plastic wrap. Wrap the sandwiches tightly so they are completely enclosed in the plastic.
Place the wrapped sandwiches in a large freezer bag, leaving a few inches of room at the top of the bag. Seal the bag tightly, removing as much air as possible. You might be able to store 10 or more sandwiches in a gallon-sized bag, but it might be more convenient to use smaller bags.
Label each bag clearly with the contents and packaging date. Place the bags in the freezer and eat them within about three months for maximum freshness.
