No pantry? No problem. If you don't have a built-in food pantry, just assign some cabinets to the task.
Ideally, choose a few large cabinets close to your refrigerator and stove.
Most kitchens have a lot of cabinets and drawers, but they are usually a chaotic mess.
You buy marinara sauce, just to find three jars hidden behind the olive oil.
Organize your kitchen food storage so you know what you have and where you have it.
For your kitchen food storage, group foods by type. Don't just stuff items into the first open space you see; instead, stock foodstuff in the same place each time, grouping like items.
In my pantry, I put crackers, chips, and other snack foods on the highest shelf not easily in reach; cereal and other breakfast items on the second shelf; pasta, pasta sauces, and boxed pasta and rice mixes on the third shelf; canned vegetables and fruit on the fourth; and soups and canned beans on the bottom.
This way, I can tell at a glance what I have and what I need to buy. If there's no oatmeal on the second shelf, I know there is no oatmeal in the house.
Put rarely used items on the tallest shelves and in the back of cabinets.
Put your family's favorite foods in the middle, at eve level. Heavy items such as cans go near the bottom.
You'll be rewarded when you carefully divide everything up, using varying sizes of containers to house your stuff, and the stuff actually stays that way. This also makes it easy for you to wipe off the dust that naturally settles there.
Finally, store bulk purchases - you know, the 17 boxes of pasta, 40 cans of chicken noodle soup, and 100 rolls of paper towels you got for a steal at the club store - in the garage or downstairs in the basement.
Call this your overflow pantry for kitchen food storage, and replenish your kitchen supply as needed.
