Have you ever walked into your kitchen and immediately noticed a smell that just won’t leave? Sometimes you can wipe down the counters, take out the trash, and scrub the sink, yet something still seems to be hanging in the air.
The culprit may be hiding in plain sight. Some everyday foods can leave strong odors, especially when they sit in the trash, linger in the fridge, or sit on the counter too long.
If your kitchen has been smelling a little off lately, check these common offenders before you blame the garbage disposal or start cleaning everything in sight.

Fish
Fish can leave your kitchen smelling like a seafood market long after dinner is over. Frying, grilling, or baking fish can release strong odors, so try cooking with lemon or vinegar to help reduce the smell.

Garlic
Garlic makes plenty of dishes taste better, but its strong scent can spread through the kitchen while you chop or cook it. The smell can also linger on your hands, and rubbing your fingers with stainless steel under running water may help remove it.
Onions
Onions are used in countless recipes, but their strong smell can hang around on cutting boards, counters, and your hands. Once onion scraps land in the trash, the odor can get even worse, so keep cut onions in a sealed container and take food scraps out regularly.
Cabbage
Cabbage may be good for you, but cooking it can leave your kitchen smelling pretty rough. According to Proactive Health Labs, cabbage releases sulfur compounds as it cooks, and boiling or steaming can make the smell more noticeable.

Broccoli
Broccoli can also emit a strong sulfur-like smell when heated. Fresh broccoli usually has a mild scent, but cooking it for a long time can leave that odor hanging around your kitchen.
Eggs
Fresh eggs have little odor, but spoiled eggs are hard to miss once the rotten smell starts to spread. Boiled eggs can also leave a sulfur-like scent behind, and hard-boiled eggs can make the smell linger if shells or leftovers sit in the trash.
Cheese
Some cheeses have strong earthy or musty smells that can quickly spread through a kitchen. Blue cheese, Limburger, and brie are a few examples, so storing them in tightly sealed containers can help contain the scent.

Trash
Your trash can may be the real source of that mystery kitchen smell, especially when it contains food scraps. Meat, old vegetables, greasy wrappers, and other leftovers can turn a trash bin into a serious source of odor if the bag sits too long.
Potatoes
Potatoes can look perfectly fine until one starts rotting somewhere in the bag. A bad potato can produce a surprisingly strong odor, so check your pantry or cabinet if you notice a rotten smell with no obvious source.
Bananas
Fresh bananas have a sweet smell, but overripe ones can develop a strong fermented odor. Banana peels can make the trash smell even worse, so remove them from the kitchen trash regularly or add them to your compost pile if you compost.
