3. Toss them into the compost pile

You may toss them into a compost pile with other materials, including eggshells, and vegetable waste.

Add in the brown materials, including shredded newspaper and coffee grounds.

The cooked vegetables may have a carbon-to-nitrogen ratio of 11:1 and 19:1.

You may add an equal amount of oat straw to obtain the carbon-to-nitrogen between 35.5:1 and 39.5:1. It is within the acceptable range.

It is preferable to use a sealed compost pile to prevent unnecessary predators.

The cooked vegetables are about 87% moisture, and excess moisture in the pile may prevent oxygen from infiltrating. It will lead to smelly, anaerobic decomposition.

The vegetables covered with fats, oils, sauces, dairy, and salt may cause complications in the composting process.

Also, do not add cooked vegetables to a compost pile where runoff is a problem. It may end up in waterways.

Can You Compost Onions?

Yes, we can compost onions. They rot down faster in the compost pile. It is preferable to avoid the onions soaked in fats and meat juices. They may attract rats and flies.
