Can you freeze red cabbage raw or cooked?
You can freeze just about anything. What you need to consider is the texture of the product when it defrosts. Cabbage, like most leafy vegetables, are full of water. As such, when they defrost, the water will leach out of its cells. You will be left with limp and mushy produce when it is thawed. This is best suited for cooked recipes, or those that don't require a crunch.
Cut the head of cabbage across the core in half. Cut out the core by cutting a V shape through the cut side of each half. Cut shreds lengthwise across each half. I'm not a big fan of blanching, but if you want to, blanch the shreds in boiling water for about 2 minutes. Cool in an ice bath, drain and bag if freezer bags.
I would portion it out depending on the recipes you're most likely to make. If for a side dish, 2-4 cups. If for an ingredient, 1 cup in small zip-top bags. Flatten the smaller bags and remove the air and place all of them in a larger freezer bag.
