I freeze in ziplocks, a ton of pyrex containers, and have started to re-use large cottage cheese containers from Costco to freeze broth and soups. I can quickly run them under hot water and then press the bottom to pop out the contents into a microwaveable bowl. When freezing in ziplocks, squeeze all the air out, and freeze on a flat baking tray with them laying on their side. After they are frozen you can stand them on edge and there is no wasted freezer space. It's also easier if you need to cut the bag off to defrost the item.
No recipe, taco soup freezes well. Homemade Mac and Cheese I freeze 1/2. If I make spaghetti sauce I freeze extra, same with taco meat. I make a basic pulled pork and have started putting more than one pork roast into the insta-pot. Saves on clean up.
I make this Chicken Wild Rice Soup and freeze 1/2. I skip the parsley and the butter, flour milk step. I just use extra broth. My son can be picky and this is a good pull out of the freezer thing for him.
