Spray your rice cooker pot with a non-stick cooking spray. This works wonders at keeping your rice from sticking and burning.
Add your brown rice and water. While the typical rice-to-water ratio for white rice is one part rice to two parts water, brown rice works better if you go with one part rice to two and a half parts water.
Add salt to taste.
On a cutting board, press the flat edge of a knife on the cloves of garlic to squash them. Remove and discard the papery skin and drop the smashed cloves into the cooker.
Add olive oil.
Cover the pot and turn on the cooker. Expect brown rice to take a little longer to cook than white rice (about 30 to 40 minutes instead of 20).
