Keto Irish Stew with Lamb and Vegetables

First I’m not in any way Irish!  But I do love a good stew and I especially love a lamb stew.

Traditional Irish stew is made with mutton, onions and potatoes.  I see people throw in carrots and peas and flour to thicken the broth.  Lots of carbs all around!

So my keto version of the traditional Irish stew omits those things, yet is still hearty and flavorful.

What you will need to make this low carb Irish Stew

  • Cubed lamb stew
  • onion and garlic
  • low carb root veggies (any combination of your choice, see next section)
  • can of Guinness stout (optional but next level!)
  • Beef broth
  • tomato paste
  • bay leaves
  • dried rosemary or a sprig of fresh rosemary

*NOTE* for buying the lamb

It’s hard to find lamb stew so your best bet is going to the butcher.  They will have lamb shoulder and will cube it for you. Lamb legs won’t work for this recipe as they don’t get tender like this when braising.

What root vegetables are low carb?

  • Turnip
  • Radishes
  • Onion
  • Rutabaga
  • Celery Root (or celeriac)

I went with a combination of some of these lower in carbs earthy vegetables for this stew.  I left the radishes whole and they looked like little potatoes!

Not a single person has questioned what was in the stew! They just gobbled it up!

Is Guinness Low Carb?

And so what about the beer?

One cup of Guinness stout has about 6.5 carbs so we are adding 1.5 carbs per serving if 4 people share this stew. 

In addition, a dark stout like Guinness adds a good amount of flavonoids, which can help combat inflammation, lower oxidative stress, and reduce the oxygenation of cholesterol.

But if you don’t want to use it, just use more beef broth!
