Low FODMAP Irish Lamb Stew – With Barley!

I cannot tell you how excited I am about this Low FODMAP Irish Lamb Stew! It all came about when I wanted to make another main dish for you all for St. Patrick’s Day in addition to the awesome Low FODMAP Corned Beef and Cabbage.

During my research I kept coming up with recipes for a warming, comfort-food stew featuring lamb and barley.

Is Barley Low FODMAP?

You might have noticed that pearl barley has a Red Light on the Monash app, and perhaps this has kept you from clicking through to read more. (ALWAYS click through to read more!)

Turns out that ⅛ cup (28 g) of cooked pearl barley is Green Light and Low FODMAP.

Pearl barley more than triples in size when cooked. 1 cup of pearl barley will yield 3 to 3 ½ cups of cooked barley. This means that approximately 2 teaspoons of raw barley will be your raw low FODMAP amount.

We have used ⅓ cup (66 g) raw pearl barley (just shy of 16 teaspoons) in our entire recipe here, which serves 9, so this serving size will yield a low FODMAP serving.

Barley, by the way, contains fructans and GOS, so if you have passed your Challenges, feel free to have a larger serving.

One Potato, Two Potato

You will notice that I call for a russet potato as well as Yukon Gold style potatoes. The floury, starchy russet is chopped and added early and will break down and help create a rich base. The waxier Yukon Gold potatoes will be added later and retain their shape.

One-Pot Wonder

This is a one pot meal that takes about 2 hours to cook, but that time is unattended while it is in the oven, where the low heat and a heavy Dutch-oven can work their magic. Once it is finished, dinner is ready!

And it even tastes better on Day 2 and Day 3!

Serve with a nice green salad.
