Crispy potato cakes made from leftover mashed potatoes, cabbage and cheddar cheese will be your new favorite side dish! They’re inspired by the classic Irish recipe colcannon, so they’re perfect for St. Patrick’s Day.
Colcannon Potato Cakes
As much as I love to experiment with new recipes, I’m super traditional when it comes to holiday meals.
This year I thought I’d try to break out of my corned beef and cabbage in the crockpot rut and try some new recipes for St. Patrick’s Day – starting with these cheesy colcannon-inspired mashed potato cakes and some Reuben soup.
What is colcannon?
Colcannon is a traditional Irish recipe made from potatoes that are mashed with cabbage or kale.
It’s one of those recipes that’s way more delicious than you would ever expect it to be – the cabbage is subtle but adds a great texture that really makes the potatoes special. I decided to take some colcannon to the next level by using it to make potato pancakes.
I also added some cheddar shreds, since I’ve never met a potato dish that isn’t better with a little cheese.
These cheesy colcannon cakes were an instant hit!
They’re crispy and salty on the outside, with creamy, cheesy mashed potatoes in the middle. If you’re planning to celebrate the holiday with a beer or two, these potato cakes are the perfect accompaniment.
What you’ll need:
To make these leftover potato cakes, you’ll need:
Leftover mashed potatoes. Use homemade potatoes or buy a tub of premade potatoes at the store.
Shredded green cabbage. Shred your own, grab a bag of coleslaw mix, or even use Brussels sprouts!
Green Onions. For extra flavor!
Milk or non-dairy milk of your choice. You’ll need just enough to loosen up the mashed potatoes.
Shredded cheddar cheese.
Neutral oil for frying.
Tips for making leftover mashed potato cakes
There are a few things to keep in mind when making these colcannon cakes.
You can use whatever nondairy milk you’d like. You only need a splash to make the potatoes creamy, so the flavor doesn’t really come through. I used almond milk since that’s what I have in my fridge at the moment, but soy milk or even unsweetened coconut milk would be fine.
Be sure to chill the potatoes for at least 15 minutes before forming the patties. It will help them firm up a little, making them easier to shape. They’ll also hold up better while they’re cooking. 15 minutes is just the minimum though – you can make them a full day ahead if you want to!
These colcannon cakes are best served hot, but you do need to let them cool for a few minutes when you pull them from the pan.
In order to keep the nice a crisp, cool them on a wire rack set on a rimmed baking sheet. This will allow any excess oil to drain away and will let air circulate around the cakes so the bottoms don’t steam and get soggy.

- Use a medium cookie scoop (2 tablespoons) to divide the potato mixture. Form into patties about ½-inch thick.
- Heat a thin layer of oil in a nonstick skillet. Add several potato cakes in a single layer, working in batches if needed, and cook for 2-3 minutes on each side, or until golden and crisp
- Blot off excess oil with a towel and transfer to a cooling rack set over a cookie sheet. Serve hot.

I am vegan so I can’t use egg. Any suggestions for a binder.
I’d try chia or flax “egg.” If you try it, let me know how they turn out!
This was sick delish! I made it twice to use up cabbage left from another recipe. Once I didn’t have green onions so I subbed two teaspoons of onion powder. Both times, I used sharp cheddar made from cow’s milk as well as lowfat cow’s milk instead of the types in the recipe. It takes a bit of prep time because of factoring in the chilling time, and I chilled mine overnight. These cakes were good at every meal and were quite addictive. I ate about three each time while cooking them up. A definite keeper!
Looks so delicious! My mouth is watering a little bit. I will certainly need to make a version of these for myself (gluten-free & real cheese).
Oh my gosh I love this spin on the classic!!! YUM!
So delicious. I could just eat a platter full of these!
What fun little potato pancakes! So creative and perfect for St Pat’s Day!
I’ve never made colcannon cakes. Add cheese and I am so making these tomorrow, thanks for the inspiration!
I’ve never had colcannon but really…the combination sells itself. These will be happening this week for sure!
I have never had colcannon but every year I tell myself I will make it around St. Patrick’s Day. It sounds awesome and who doesn’t love potatoes, cabbage and cheese?
As far as I’m concerned, you can’t go wrong with anything that includes potatoes, “cheese”, and fried all in the same dish. These sound fantastic, I’m glad you tried something besides your norm!
