Cauliflower Colcannon: Irish Mashed Potatoes
I know it’s last minute but I wanted to share a quick and easy keto friendly twist on Colcannon (Irish Mashed Potatoes). Just as there’s a thousand mashed potato recipes, there are just as many Colcannon variations.
Obviously the biggest change is using cauliflower instead of the traditional starchy carb filled potatoes. Colcannon can be mixed with kale, cabbage, leeks and a variety of other veggies but for these low carb cauliflower version I’ve chosen to incorporate cabbage and chives.
Feel free to make changes and substitutions to meet your palate.
Colcannon can be used as a base for Bangers & mash or as a lovely topping for your Shepherd's Pie. You don’t have to have Colcannon only on St. Paddy’s as this classic Irish side dish goes great with salmon and or beef as well.
Irish Whisky Gravy
It just didn’t seem right to make a Keto Colcannon without having an Irish gravy to serve along side it plus it was an excuse for me to bust out the bottle of bushmills from the liquor cabinet.
The combination of whisky and mushrooms has always been a favorite of mine so taking those ingredients and using them to make a gravy seemed like a natural culinary progression.
You can use whatever beef broth you like from a grass fed bone broth to a few cubes of bouillon. If you are really in a pinch you can also use a beef gravy powder packet and just omit the xanthan gum as most of these packets have corn starch or another thickening agent.
This will increase the amount of carbs in the dish and I know a lot of ketonians avoid corn in any form due to the use of gmo.
Irish Grass Fed Cheese and Butter: Kerrygold
I added Kerrygold dubliner cheese to the Colcannon. Not only to tighten up the cauliflower but to add a nutty cheese flavor as well.
Dubliner cheese reminds me of a sharp cheddar because of it bite and subtle tang. It’s a fantastic cheese for all sorts of applications from melting on burgers to slicing and serving on a ploughman's platter. We keep this cheese on hand year round.
Admittedly it’s much easier to find in March around St Patrick’s Day. Kerrygold butter is also my favorite butter to use for all my Keto recipes because of its creamy rich flavor and quality.
Between these two products you know you’re going to have a fantastic final product. I find that any recipe will only be as good as the ingredients you use in it.

I made the colcannon without the gravy to go along with Frank's recipe for a smoked Corned beef brisket. This recipe was terrific. It was extremely easy... so easy that I could make it while watching over a 10 week old Great Dane puppy. It was delicious. Try this recipe... You will be glad that ya did!
Thank you so much for the feed back. so glad you enjoyed the recipe
