When I first discovered Brotchán Roy, otherwise known as the King’s Soup, I knew I would love it. It was said to have been the favorite dish of Ireland’s celebrated sixth-century spiritual and literary icon, St. Columkille.

Steel cut oats are loaded with fiber, they are great for your heart and give the soup a wonderful texture. If you don’t have steel cut oats, you can use Quaker oats, reducing the cooking time to about 25 minutes. If you’re on a gluten free diet, make sure your oats are labeled gluten-free. This is my modified take on the classic, hope you like it!

  1. What is the serving size for this?

  2. I’ve made this recipe so many time I can’t count! Even my oatmeal-disliking husband likes it. Really good on a chilly evening with a good salad. 

  3. Maybe my grocery store just has massive leaks but 1 was enough to double the recipe.

  4. I make an oatmeal congee quite similar to this…. love it. I can’t stand sweetened oatmeal, have been looking for more ways to make savory oatmeal.
    Can’t wait to try this!!

  5. This isn’t actually a soup. It’s leek Oatmeal.

  6. Loved this recipe!! To speed up actual cooking time for Irish oats, bring the liquid to a boil in the microwave, add the oats, bring it back to a boil, then set it aside for several hours or overnight. The oats will soak up most of the liquid so it only takes a few minutes to finish cooking. This works better than a slow cooker.

  7. This soup is delicious! I did cream it to hide the leeks from the kids, but they devoured it! No complaints when they asked about the ingredients. I gave them the summary on the soup above and they were more focused on wondering why it was called King’s Sou as they ate it. Will definitely make it again as it is a comforting soup.

  8. Hi Gina! I LOVE this recipe, and was wondering if you have ever tried in in the Instant Pot? I find that I am not that adventurous with knowing how to convert recipes from stovetop to IP. 🙁

    I’ve made this several times before, tonight I am going to add some baby portabellas to it and see how that ends up!

    Thank you!

  9. Four out of five at the table loved it, only one fuss-budget was undecided. Used a hand blender for a smooth and creamy big mug of soup. Delicious!

  10. I would really recommend using a stock pot for this. The amount of liquid used in this recipe comes nearly to the top of a medium sauce pan and as soon as it starts to boil, the milk wants to boil over onto the stove. Very messy. 

  11. what a page, I love it! my cousin found you and I took the linc to see what other recipes you have…nicely laid out and clean looking great presentation of food’

  12. A friend made this a St. Patrick’s day dinner. It is awesome. Very tasty.

  13. Hi Gina, can I use rolled oats for this recipe? Thanks

  14. I usually don't eat dishes that don't have meat it them (I was even tempted to add shred chicken to this but didnt), and my clever fiance grabbed kolrabi instead of leeks so my recipe turned out a little different than expected. Even without the leeks, and the kolrabi taking its place, it turned out to be a very delicious dish. It's picky eater approved 🙂

  15. Perfect to take to my St. Patrick's potluck at work, a big hit!

  16. I made this last night and it was so good! Having it for lunch again today 🙂

  17. i gave up meat for Lent AND have a hubby who is an Irish citizen- double win for us both! will be making to St Paddy's Day!
