Yes, you can freeze unbaked meatloaf for later use. Here are some steps to follow: Cover the prepared meatloaf tightly with plastic wrap and then with aluminum foil. Freeze for up to 3 months. When you're ready to bake the meatloaf, thaw it overnight in the refrigerator and bake as directed. Note: It's important to thaw the meatloaf completely before baking it, as cooking a frozen meatloaf can result in uneven cooking and potentially food safety concerns.
