Masala Aloo Gobi can be made ahead of time, cooled down, and then stored in the fridge for 4-5 days. You can freeze it as well if you want. But the flavors and textures may get compromised. Thaw it in the fridge overnight and then reheat. Also, remember to refrigerate or freeze only once the cauliflower curry has cooled down completely. Another way of storing is to prepare the curry without prepping the cauliflower and potatoes. Store them in the fridge or freezer. Fry the aloo and gobi fresh as and when needed and then add to the curry when reheating.
