Freezer Meal Instructions:

To Freeze:

  1. Complete recipe through Step 4. DO NOT BAKE before freezing. Wrap casserole dish tightly in a few layers of plastic wrap and one of foil and place in the back of the freezer.

To Prepare:

  1. Thaw in the fridge for 24 hours and bake according to directions. Or defrost in the microwave and bake. If baking from frozen, cover oatmeal with foil and plan to bake longer, until the middle is cooked through. If cooking directly from frozen, the USDA states that, “it will take approximately one and a half times as long to cook.”
