Ingredients You’ll Need
- 2.5 lbs. russet potatoes (peeled and diced): These starchy potatoes make for a creamy mash, and russets yield a wonderful texture. If you’re in a pinch, Yukon Golds work too.
- 1/2 head cabbage (rough chopped): This adds a subtle sweetness and nutritional punch. If you’re not a cabbage fan, you can skip it or use kale instead.
- 4 chicken bouillon cubes: They infuse the potatoes with a savory flavor. Vegetable bouillon is a great alternative for a vegetarian option.
- 1/2 tsp. garlic powder: This gives the dish a subtle garlicky note without overpowering the other flavors.
- 1/2 tsp. onion powder: A fantastic way to enhance the overall taste, blending seamlessly with the other ingredients.
- Water to cover: You’ll want enough water to cook the potatoes and cabbage thoroughly, but don’t overfill!
- 1/2 cup half and half (or milk): This adds creaminess, but if you’re looking for a lighter version, use reduced-fat milk or a non-dairy substitute.
- 1/2 cup salted butter, melted: Unquestionably important for rich flavor; you may use unsalted if controlling sodium intake.
- 3/4 tsp. salt: This helps balance the flavors, but adapt it to your taste preferences.
- 1/4 tsp. pepper: A subtle seasoning that rounds out the dish.
- 8 slices bacon, cooked and crumbled: Bacon brings an irresistible crunch and smokiness; vegetarian bacon can be used for a meat-free alternative.
- 1/2 cup sliced green onion: A fresh, vibrant touch that adds a pop of color and flavor right before serving.
How to Make Slow Cooker Colcannon Potatoes | Easy Crockpot Dinner

- Add Ingredients to the Slow Cooker: Begin by adding the peeled and diced 2.5 lbs. russet potatoes and the rough chopped 1/2 head cabbage into the slow cooker. Toss in the 4 chicken bouillon cubes, 1/2 tsp. garlic powder, and 1/2 tsp. onion powder.
- Cover with Water: Pour in just enough water to cover the potatoes and most of the cabbage. Don’t worry if some of the cabbage isn’t submerged—you don’t want to risk overflowing!
- Cook: Place the lid on the slow cooker and set it to cook on HIGH for about 4.5 hours. You want the potatoes and cabbage to become tender and easily mashable.
- Drain the Remaining Water: When the cooking time is up, carefully drain off the excess water from the potatoes and cabbage.
- Mix in Creamy Ingredients: Pour over the melted 1/2 cup salted butter, 1/2 cup half and half, 3/4 tsp. salt, and 1/4 tsp. pepper. This step is crucial for achieving that creamy, dreamy texture.
- Mash: Using a potato masher, mash the mixture until you reach your desired consistency. Feel free to add a bit more half and half if the potatoes seem dry—just be cautious not to overdo it!
- Add Bacon and Green Onions: Fold in the crumbled 8 slices bacon and 1/2 cup sliced green onion for a fresh finish, stirring until everything is well combined.
- Serve and Enjoy: Spoon into bowls and serve hot, garnished with extra green onions if desired.
Storing & Reheating
Leftovers should be stored in an airtight container in the fridge for up to 5 days. You can also freeze these colcannon potatoes for up to 3 months. When reheating, microwave in short bursts, stirring in between, until heated through. Adding a splash of half and half or milk can help restore creaminess since the texture may change slightly in the freezing process.
Chef’s Helpful Tips
- Avoid overcooking the potatoes; you want them tender but not falling apart. Keeping them diced uniformly helps.
- If your potatoes seem too thick or dry after mashing, a little bit of extra half and half will do the trick!
- Test for seasoning before serving—sometimes, a pinch more salt can elevate the flavor beautifully.
- You can prepare the potatoes and cabbage the night before and just mash everything the next day for a quicker meal.
- For a creamier version, use a hand mixer instead of a potato masher; just don’t overmix as they can get gluey!
