Substitutes for rolled barley

1 cup rolled barley = 1 cup old-fashioned rolled oats (Greedy Gourmet)
Closest match in form and cooking time (5–10 min). Oats are gluten-free (when certified) and milder in flavor; barley is chewier and nuttier.
1 cup rolled barley = 1 cup rolled rye, spelt, or wheat flakes (Greedy Gourmet)
Other rolled whole-grain flakes swap 1:1 in porridge, granola, and muesli with similar texture. All contain gluten.

Rolled barley conversions: FAQ

Why doesn't a cup of rolled barley weigh the same as a cup of water?

A cup measures volume, not weight. Rolled barley is less dense than water (100 g versus 237 g per cup), so the same volume has a different weight. Weighing in grams is the most accurate way to measure it.
