Can You Compost Rice and Pasta?
Yes, with care. Plain rice and pasta compost, but cooked leftovers attract rodents and can turn slimy. Add small amounts buried in the center of an enclosed bin, or use bokashi.

How to compost rice and pasta
Add plain leftovers a cup or two at a time, buried in the center of the pile and covered with browns. Dry, uncooked rice and pasta can go in too; they break down more slowly. Anything with meat, cheese, cream or lots of oil belongs in bokashi or the food-scrap bin.
Municipal food-scrap programs usually take cooked starches, and bokashi handles them at home without pest risk.
What goes wrong
Cooked rice clumps into a sticky mass that goes anaerobic and smells. Break it up and mix it with dry browns. If rodents show up, stop adding cooked starches.
Worm bins and bokashi
Worm bin: Worms will eat small amounts of plain cooked rice or pasta, but excess sours the bin quickly.
Bokashi: Rice and pasta, plain or sauced, ferment well in bokashi.
This counts as a green. Adding a lot of it? Check the balance with the compost mix calculator.

Frequently asked questions
Can you compost cooked rice?
Yes, in small amounts buried in the center of an enclosed bin. The main issues are rodents and a sticky clump that smells, so mix it well with dry browns.
Can you compost uncooked pasta or rice?
Yes. Dry pasta and rice break down slowly but attract fewer pests than cooked leftovers. Break long pasta up first.
Can you compost pasta with sauce?
Tomato-based sauce is fine in small amounts. Creamy, cheesy or meat sauces should go to bokashi or municipal collection.
