To find your microwave’s wattage, look at the front panel, the side of the door, in the back, in the user manual, or Google the model number. If both an input and output wattage are listed, use the output.

Wattage translates to how powerful the microwave is. The higher the wattage, the faster your food will cook. The lower the wattage, the longer the cook time.

When in doubt, start with less time — you can always add more.

Ingredients

Blueberry & Cream Oats

  • ½ cup fresh blueberries, or frozen
  • 2 tablespoons brown sugar
  • 4 tablespoons heavy cream, or coconut milk

Banana & Peanut Butter Oats

  • 1 banana, thinly sliced
  • tablespoons peanut butter
  • 4 teaspoons sugar (optional)

Preparation

  1. In a large bowl, mix cooked rolled oats with desired flavor add-ins.
  2. If the cooked oats are still warm, transfer to a baking sheet and spread into an even layer. Transfer to the fridge until fully cooled.
  3. Portion oats into the cups of a ½ cup Anytime Tray and cover with the lid. Freeze overnight, or at least 6 hours.
  4. To reheat from frozen: Place a frozen oatmeal portion into a Anyday Small Dish. Add 1 tablespoon water and then cover with lid (knob lifted). Cook in the microwave for 1-2 minutes, or until the oatmeal is hot and thick.

Serving suggestions & tips

  • When reheating, use water or milk (dairy or plant-based) for a creamier, richer texture.
  • You can keep your oatmeal plain or add any sweetener such as sugar, maple syrup, honey, or stevia.
  • For a savory twist, substitute the fruit suggestions with cooked mushrooms and corn.

  • Parent trick:
    Add some fresh fruit to each compartment for a variety of flavors. Or add the fresh fruit as a topping after reheating.
  • Microwave ovens vary, even with the same wattages. Adjust cooking times as needed.
