Frozen kale is a fantastic alternative to spinach, offering a quick and easy way to add a nutritional boost to your meals. The Anyday dish, with its vented lid, allows us to use just a small amount of water to steam the kale, preserving all the natural nutrients and vibrant colors. Plus, when you cook frozen kale in the microwave, there’s no need to thaw it before cooking, saving you even more time!

All of Anyday’s recipes are tested (and retested!) in many different microwaves and home kitchens to make sure they work — and work well. Unless specified otherwise, all recipes should be cooked at full power.

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.
