Spinach is a nutrient powerhouse. It’s rich in vitamins, including vitamin C, vitamin K, and vitamin A, and it’s chock-full of essential minerals, like iron and calcium, too. Plus, it’s a good source of fiber and antioxidants. The bottom line is that eating spinach is great for your body. But is it better fresh or frozen? It depends.
Is frozen spinach healthier than fresh?
There is a big downside to spinach. When it’s bought fresh, all of its nutritional superpowers start to wilt pretty quickly.
According to 2005 research from Penn State University, the nutrients in spinach start to degrade quickly. This means that if it has already been shipped long distances before it lands in the grocery store, by the time it gets to your fridge at home, it may have lost much of its nutrient content.
“When fresh spinach sits during transportation over long distances or stays in your refrigerator for a week, its folate content drops so much that frozen spinach becomes the better source,” Mary Ellen Phipps, MPH, RDN, LD, wrote for CNBC in 2022.
This is because frozen spinach often goes through a flash-freezing process just hours after it has been harvested, which helps to lock more of its nutrients in. “One cup of frozen spinach has more than four times the amount of nutrients, including iron, vitamin C, and calcium, compared to a cup of fresh spinach,” adds Phipps.

The catch is while frozen spinach is great for soups, stews, pastas, and so on, it’s not so great for salads. If you’re buying fresh spinach, there are a few important things to look out for. For example, make sure it has dark green, crisp, healthy-looking leaves, and avoid bags of spinach that look yellow and limp.
It’s also a good idea to check best-before dates, as well as shipping locations, to find out how long the spinach has been on the shelves and how far it has traveled.
Beyond nutrition: more benefits of cooking with frozen spinach
Frozen spinach is nutritious, but it also offers many other benefits. It helps to cut down on food waste, for example, because after use, it goes back in the freezer ready to be used again, instead of wilting away in the fridge. In fact, frozen spinach can be stored in your freezer for up to a whole year, while fresh spinach is only good for about 10 days or so in the fridge.
Frozen spinach’s long life doesn’t just cut down on waste, but it cuts down on cost, too. Many of us are guilty of buying fresh, using one portion, forgetting about it, and then throwing it away, only to have to buy more soon after. But buying frozen means you get your money’s worth before the spinach has a chance to wilt.
Frozen spinach is also incredibly easy to cook with. Keep a bag on hand in the freezer, and then pull out a few cubes to throw into dishes like bolognese, lasagna, stew, soup, casseroles, and more. It’ll wilt into the food in a matter of minutes, adding an easy boost of extra nutrition.
