All that de-cluttering and organizing tends to focus on living areas, but have you considered doing the same with your refrigerator?
Often times kitchens are limited on refrigerator size based on the appliances’ location. For example, I know I couldn’t possibly get a bigger fridge on account of the fact it needs to fit right into an area carved out for it under and next to cabinets in our kitchen.
That being said, as of right now the fridge only accounts for two people (and two animals), so storage isn’t exactly a concern of ours. However, one day it very well might be. And so we’ve already started the practice of relegating our frozen vegetables and meats to a basement freezer.
Back in the day I feel a lot of people opted for this same strategy by way of a garage refrigerator, or extra one in the basement. However, most things that require refrigeration (outside of beer, for example) will likely have an expiration date. As a result, you’ll either need to stay on top of rotating out those items, or face the possibility of growing your own science experiment in the back corner of the fridge.
You can pick up a deep freezer like the one my wife and I have more or less on the cheap. New ones are available on Amazon for $150-$200, and used ones may even be available for less on Facebook Marketplace, Craigslist, LetGo/OfferUp.
