  1. Take one or two cinnamon sticks and place them in a pot of water. Put the water on high heat, bringing it to a boil. Let the mixture boil for a while, releasing the scent of the cinnamon into the air. The cinnamon will help disguise the odor in your kitchen and house.
    • Make sure you watch the water levels in your pot. You want to keep plenty of water in your pot so it doesn't burn and cause more unpleasant smells in your kitchen.
  2. Just like it eliminates odors on your hands, you can use baking soda to reduce odors in the air as well. Take a few tablespoons of baking soda and combine it with a generous amount of water in a slow cooker. Turn the slow cooker to low heat and leave the top off. The heated baking soda will help pull the odors from the air. [1]
    • Instead of just eliminating odors, you can turn this method into an air freshener as well. With the baking soda, try adding a few drops of vanilla, a few teaspoons of your favorite spices such as cinnamon or clove, some essential oils, or a few slices of lemon. The baking soda will still eliminate the smell and the extra ingredients will replace the smell of onion with a fabulous new fragrance.

Anything that has a naturally pleasing aroma will help cover up the odor of the onions and exchange it for the smell of baked goods. The added bonus is that you will have a yummy dessert after you're through.
