Why You’ll Love This Recipe
- Simple & Quick: It takes just 20 minutes of prep time, then let your slow cooker work its magic for 4.5 hours.
- Irresistible Flavor: The combination of rich butter, creamy potatoes, and savory bacon creates a flavor explosion.
- Eye-Catching Appeal: The vibrant colors of green onions and cabbage make it a beautiful dish to serve.
- Flexible Serving: Perfect as a side for dinner or even as a main dish on chilly nights.
- Diet-Friendly Options: Easily customizable for vegetarian friends by omitting bacon or opting for veggie broth.
Ingredients You’ll Need
- 2.5 lbs. russet potatoes: Peeled and diced, these create the creamy base of your colcannon. Russet potatoes are starchy and perfect for mashing.
- 1/2 head cabbage: Roughly chopped, cabbage adds a subtle sweetness and texture. Savoy cabbage can make a delightful substitute.
- 4 chicken bouillon cubes: These deepen the flavor, providing a salty umami richness. Vegetable bouillon is a great alternative for a vegetarian version.
- 1/2 tsp. garlic powder: Adds a warm, savory depth to the dish. Fresh garlic can also be used for a more aromatic flavor.
- 1/2 tsp. onion powder: Complements the garlic for a rounded taste, or use finely chopped onions for freshness.
- Water: Just enough to cover your vegetables, allowing them to steam perfectly.
- 1/2 cup half and half (or milk): This adds creaminess. Use heavy cream for richer potatoes; almond or oat milk works well for dairy-free options.
- 1/2 cup salted butter: Melted, this makes for an indulgent finish. Unsalted butter can replace it, but you’ll need to adjust the salt to taste.
- 3/4 tsp. salt: Adjust based on taste preference, remembering that bacon is also salty.
- 1/4 tsp. pepper: Freshly cracked pepper enhances the overall flavor.
- 8 slices bacon: Cooked and crumbled for that crunch factor. You can skip this for a vegetarian version, or use turkey bacon.
- 1/2 cup sliced green onion: These provide freshness and a pop of color, though chives can be a fabulous substitute.
How to Make Slow Cooker Colcannon Potatoes | Easy Crockpot Dinner

- Combine the main ingredients: Start by adding the peeled and diced russet potatoes and roughly chopped cabbage to the slow cooker. Toss in the chicken bouillon cubes, garlic powder, and onion powder for extra flavor.
- Add water: Pour in just enough water to cover the potatoes and most of the cabbage. It doesn’t need to be exact; some cabbage can peek above the water. Make sure not to overfill, as it may overflow during cooking.
- Set the cooker: Cover with the lid and set your slow cooker to HIGH. Let it work its magic for 4.5 hours.
- Drain water: Once the cooking time is up, carefully drain the water from the potatoes and cabbage, leaving behind the tender veggies in the slow cooker.
- Incorporate creaminess: Pour the melted salted butter and half and half over the potatoes, then add the salt and pepper.
- Mash it up: Using a potato masher, mash everything together, ensuring it’s silky smooth. If the potatoes seem a bit dry, feel free to add a touch more half and half for the perfect texture.
- Finish with flavor: Add the crumbled bacon and sliced green onions to the mix, gently stirring until everything is well combined. Serve warm and enjoy every delicious spoonful!
Storing & Reheating

- Add extra half and half in small amounts while cooking to avoid a soupy consistency.
- Experiment with herbs, like fresh parsley or thyme, to elevate flavors.
- Make it ahead of time! This dish can be prepared in advance and tastes even better the next day.

Recipe FAQs
Can I use sweet potatoes instead of russet potatoes?
Absolutely! Sweet potatoes offer a delightful twist on colcannon, adding natural sweetness and a hint of color. Just keep in mind they may need less cooking time, so check for doneness after 4 hours.
How can I make it vegan-friendly?
To make a vegan version, simply replace the half and half with plant-based milk, use vegan butter, and omit the bacon. For added flavor, consider sautéing some mushrooms to add that rich, savory element.
Can I prepare this recipe the night before?
Yes! You can prep all the ingredients the night before, store them in the refrigerator, and simply place them in the slow cooker the next day. Just remember to adjust the water level accordingly based on how the cabbage may have released moisture overnight.
How do I know when the potatoes are done cooking?
The potatoes are perfectly cooked when they can be easily pierced with a fork or knife. If they feel soft and can be mashed easily, they are ready for mashing. Enjoy your slow-cooked masterpiece!
