Microwaving frozen spinach in an Anyday dish is a great way to get a nutritional boost, fast. Fresh spinach can be bulky and take up a lot of space — not to mention it goes bad super fast — but frozen spinach is compact and sits happily in your freezer. Microwaving it retains its nutrients better than cooking it on the stovetop.

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.
