Ingredients You’ll Need
- 2.5 lbs. russet potatoes: Peeled and diced, these sturdy potatoes are perfect for making creamy mashed potatoes. Feel free to substitute with Yukon gold potatoes for a buttery flavor.
- 1/2 head cabbage: Roughly chopped cabbage adds a subtle crunch and a healthful twist to your dish.
- 4 chicken bouillon cubes: These add a depth of flavor to the potatoes and cabbage, making them more savory. If vegetarian, use vegetable bouillon cubes instead.
- 1/2 tsp. garlic powder: This brings aromatic goodness that’s hard to resist.
- 1/2 tsp. onion powder: A dash of this adds a mellow onion flavor without the bulk.
- Water to cover: This will help the potatoes and cabbage cook evenly—just don’t overfill your slow cooker!
- 1/2 cup half and half (or milk): Creaminess is key, and half and half makes for an ultra-rich texture. You can also use almond milk for a dairy-free version.
- 1/2 cup salted butter: Melting butter adds a luxurious mouthfeel and flavor. For a lighter version, try a dairy-free butter substitute.
- 3/4 tsp. salt: This enhances all the flavors—be sure to adjust according to your preference.
- 1/4 tsp. pepper: Just enough to balance the richness of the dish.
- 8 slices bacon, cooked and crumbled: Bacon adds that smoky, crunchy element everyone loves. For a vegetarian version, try using sautéed mushrooms for umami.
- 1/2 cup sliced green onion: These bring a fresh bite and color contrast, elevating the dish in both taste and presentation.
How to Make Slow Cooker Colcannon Potatoes | Easy Crockpot Dinner

- Prepare the Vegetables: Place the peeled and diced russet potatoes and chopped cabbage into the slow cooker. Sprinkle the chicken bouillon cubes, garlic powder, and onion powder over the top.
- Add Water: Pour in just enough water to cover the potatoes and most of the cabbage. It’s all right if some cabbage peeks out—this dish can handle it! Remember not to fill your slow cooker to the brim to avoid overflow.
- Cook: Cover the slow cooker with its lid. Set to HIGH and let it cook for about 4.5 hours. You’ll know it’s ready when the potatoes are fork-tender and the cabbage is beautifully soft.
- Drain: Once the cooking time is up, carefully drain the water from the potatoes and cabbage. Watch out for steam—it can be hot!
- Add Creaminess: Pour the melted butter, half and half, salt, and pepper over the drained mixture. This will give your potatoes that delectably creamy texture.
- Mash: Grab your potato masher and mash everything together. If the potatoes look dry, feel free to add a splash more half and half—you’re going for creamy perfection.
- Mix in Extras: Finally, fold in the crumbled bacon and sliced green onions. Give it a good stir, and voilà—your dish is ready to serve!
Storing & Reheating
If you have leftovers (which is uncommon with such a crowd-pleaser), let the colcannon potatoes cool down before placing them in an airtight container. They’ll stay fresh in the fridge for up to 3 days. You can also freeze them for up to 3 months—just make sure to use freezer-safe containers. When you’re ready to enjoy again, simply reheat in the microwave or on the stovetop, adding a splash of milk or cream to revive that creamy texture.
Chef’s Helpful Tips
- Make sure the bacon is crispy before mixing it in; soggy bacon doesn’t have the same delightful crunch.
- For perfectly creamy potatoes, don’t overwork them while mashing—gentle is the way to go!
- Vary your seasonings! Adding a sprinkle of smoked paprika or even a dash of hot sauce can take flavors to the next level.
- Want to make this ahead? You can prepare everything in the slow cooker the night before and refrigerate, then start cooking in the morning.
If you’re looking for a comforting and hearty meal, these Slow Cooker Colcannon Potatoes are the answer.

Don’t shy away from experimenting with flavors or ingredients—make it your own! When you serve up this dish, you’re not just feeding your family; you’re feeding their hearts too.
