Steel Cut Oats: Grams to Cups

Convert grams of steel cut oats to cups. 1 US cup = 181g. Steel cut oats (also called Irish oats or pinhead oats) are whole oat groats cut into pieces rather than rolled, making them denser than rolled oats.

Steel cut oats (181g/cup) are significantly denser than rolled oats (90g/cup) because they are whole, thick pieces rather than flat, light flakes. They take longer to cook (20-30 minutes) but have a chewier texture and lower glycaemic index.
