Having never gone to culinary school or worked the line in a restaurant, I often find myself learning about food the hard way. When I landed my first gig as an assistant food stylist, one of those learn-from-my-mistakes moments happened when I stored tomatoes in the walk-in refrigerator of the TV studio kitchen where I worked. Whoopsies! Turns out cold boxes can be a “tomb of death” for tomatoes, transforming them from delicious, photogenic beauties to wrinkly, mealy messes not exactly ready for their close-up (or for your sandwich).
But having grown up in a three-freezer household, my instincts tell me that whenever I can score a deal, I should buy extra. And when tomatoes are in their prime, they’re also at their most affordable. So if you can’t refrigerate tomatoes, what can you do?
It turns out that even though refrigerating tomatoes is terrible, freezing them is totally doable with one clever trick. Since tomatoes are made of mostly water, you can’t freeze them as is, BUT if you dry them out prior to freezing, it protects their structure, preserves their flavor, and stocks your freezer full of their sunshine all year long. And you don’t even need a fancy dehydrating contraption to do it.
First, set your oven to 225° F. Line a sheet pan with parchment paper and place a wire cooling rack over the top.
Next, slice a bunch of tomatoes in half. I like to use cherry or grape tomatoes because they dry out more quickly, but you can do this with any variety of tomato. Keep in mind, the bigger the tomato, the longer it’ll take to cook. (This trick will help you slice through three pints of small tomatoes fast.)
Arrange the tomatoes cut side up on the cooling rack and season them. I recommend keeping it simple with just salt and pepper, but if you want to add spices, chopped garlic, or dried herbs, go for it. I might prefer to-may-to, you might prefer to-mah-to. The good news is that either is great on a cold December night.
Cherry or grape tomatoes will take about three hours to dry out. You’ll know they’re done when they’re pruning up (think fingertips approximately one hour into a hot bath) and have shrunk to about half their original size. Allow the tomatoes to cool completely.
Once cool, dump them onto the parchment paper and place the entire sheet tray in the freezer. Once they’re fully frozen (I like to leave them there overnight to be safe, but four hours oughta do it), place the frosty tomatoes into a ziptop bag and put them back in the freezer.
