You are watching: What can you do to minimize the smell of onions when preparing them?
The smell of freshly brewing coffee will help, but it’s really the spent grounds we’re after here. Coffee contains nitrogen, which neutralizes odors. Spread your wet coffee grounds out on a baking sheet to dry and just leave them out overnight. (You can also put these used-and-dried grounds in a bowl in the fridge to battle odors in there!)Related: The Last Thing You Should Do with Used Coffee Grounds
The best way to avoid odors is to blow them outside. If you have a vent over your stove, use it! Otherwise, an air conditioner or an air filter can help remove the stench. Opening a window before you start cooking helps with air circulation, especially if you position a fan pointing out the window. If you forgot to open the window ahead of time, open it now — any little bit will help!
Wipe splatters on the stove and countertop, and wash all greasy cooking pans right after cooking. It’s best to take care of a pan full of stinky oil that evening rather than letting the smell emanate overnight. Don’t forget to clean the drain of leftover food particles, run the garbage disposal, and take the trash out, too!

Save your lemon rinds! Pleasant-smelling spices like cloves, cinnamon sticks, or citrusy lemon peels can be simmered in water on the stove for an all-natural air freshener that’ll mask any cooking smells. The potpourri steam is especially nice in the cooler/drier months. Just something to file away for winter.
