I stumbled upon this colcannon soup creation during a frosty night when plain potato soup just wouldn't cut it. I combined all the best elements of classic Irish colcannon—creamy spuds, soft kale, crisp cabbage, and thick cream—and transformed them into a dish that'll heat you up completely. It's become our top pick for cold-weather eating.
Heartwarming Comfort
Each bite delivers that soul-satisfying potato goodness with added benefits from nutritious greens. It amazes me how basic ingredients come together to create magic. This soup works perfectly for St. Patrick's Day celebrations or anytime you're looking for something to cuddle up with. It's basically comfort in soup form.
What You'll Need
- Garden Goods: Washed leeks for a mellow flavor foundation; vibrant kale and cabbage add both color and healthy benefits.
- Main Players: Quality russet potatoes that break down beautifully for a thick texture.
- Liquid Foundation: Chicken stock works wonderfully, but veggie stock fits the bill too if that's your preference.
- Luxury Touch: Full-fat heavy cream because it's worth it—this ingredient creates that silky texture you'll crave.
Cooking Steps
- Begin With Vegetables
- Warm some butter in your largest cooking pot; gently sauté the leeks, cabbage, and kale until everything softens nicely, roughly 15 minutes.
- Create The Foundation
- Add your chunked potatoes, pour in stock, drop in bay leaves, sprinkle salt; let everything simmer until potatoes become super tender.
- Add Richness
- Stir in your heavy cream, season with white pepper, mix in chopped green onions; sample and tweak seasonings until it tastes just right.
- Time To Eat
- Remove those bay leaves, pour into serving bowls, and scatter some extra green onions or parsley on top if you want.

Pro Tips
Don't skimp on getting good greens—they really boost the overall taste. Cook those leeks slowly and carefully until they're soft and sweet without browning. I often squash some potato chunks against the pot with my wooden spoon to thicken everything up. These small touches transform an ordinary soup into something folks will talk about.
Perfect Pairings
This soup begs for a crusty loaf to mop up the bowl. Traditional Irish soda bread makes an ideal partner. Sometimes I'll add a plate of oven-roasted veggies or a simple green salad to balance the richness. Nobody at my table ever leaves a drop behind.
Storing Extras
Any leftover soup can go in the fridge for up to 3 days. When it's time to reheat, do it gently with occasional stirring. Always use low heat since cream-based soups can separate if they get too hot too fast. You might notice the flavors deepen and improve overnight.
Easy Changes
Feel free to swap in spinach or Swiss chard if you're not crazy about kale. Trying it with sweet potatoes instead gives a lovely twist. Can't do dairy? Coconut milk makes a surprisingly good substitute that keeps everything luscious while adding a subtle new flavor note.

Personal Touches
Try topping your bowl with some crunchy bacon pieces for extra wow factor. I sometimes fold in sharp cheddar right before serving. My little ones go wild for a sprinkle of toasted nuts on top or a drizzle of fancy olive oil. The best dishes evolve as you make them again and again, collecting family memories with each new addition.
Frequently Asked Questions
- → Why choose Russet potatoes?
Russets naturally break down, making the soup thick and creamy. They're full of starch, which gives you that velvety texture.
- → What exactly is lacinato kale?
It's also called dinosaur or Tuscan kale—smoother and softer than regular kale. If using curly kale, just cook it a bit longer.
- → What's special about white pepper?
It gives a mild heat without those black flecks, so your soup looks neat. Swap it with black pepper if you prefer.
- → Can I go meat-free?
Absolutely. Just use vegetable broth instead of chicken broth. The rest of the ingredients are already veggie-friendly!
- → Why cook the greens first?
Slowly sautéing greens in butter makes them tender and flavorful. Rushing this step might result in chewy or bitter greens.
