We have an America Fridge Freezer in the kitchen so the freezer compartment is tiny. We have always had a larder freezer in the garage. It is a Beko and specifically stated it could be kept there.
We shop at Costco so bring home 1 pack of chicken breast which contains 12-13 breasts so we freeze them, same with minced steak at 2.5kg, gallon freezer bag, roll flat (defrosts quicker) and freeze. Label everything. Roast down peppers, onions, courgettes, tomatoes etc for a med veg pack to go with salmon or chicken. Portion and freeze.
Agree with any reduced items, or large tubs of ice-cream, freezer packs and desserts. If you meal plan you will know to remove something from the freezer and don't forget you can make bases for sauces which you can add to to change it ie basic tomato sauce for a pizza base or once defrosted add in more garlic, basil/oregano for pasta. I am making baked ziti tomorrow night for dinner, so spag bol sauce from freezer.
My rule of thumb is make 3, when making a meal for tonight triple up the recipe and freeze 2. Don't forget foil trays for lasagne rather than using up your dishes from the kitchen and ziplock bags, gallons and quarts.
