Ingredients You’ll Need
- 2.5 lbs. russet potatoes (peeled and diced): These starchy potatoes create the perfect creamy texture. If you’re short on time, Yukon Golds are a great alternative.
- 1/2 head cabbage (rough chopped): Cabbage adds a sweet, earthy flavor. You can swap it with kale for a different twist.
- 4 chicken bouillon cubes: These add a depth of flavor. You can use vegetable bouillon for a vegetarian version.
- 1/2 tsp. garlic powder: This enhances the overall flavor without overpowering the dish.
- 1/2 tsp. onion powder: It pairs beautifully with the garlic, providing a subtle savory note.
- Water to cover: This hydrates the potatoes and cabbage while cooking, ensuring they soften completely.
- 1/2 cup half and half (or milk): This gives the mashed potatoes a luxurious creaminess. Dairy-free milk can be a good substitute.
- 1/2 cup salted butter, melted: Butter adds richness and flavor. For a lighter version, swap with olive oil.
- 3/4 tsp. salt: Enhances all flavors; feel free to adjust according to taste preferences.
- ¼ tsp. pepper: This adds a bit of warmth; you can add more for extra kick if desired.
- 8 slices bacon, cooked and crumbled: Provides a crunchy texture and savory flavor; turkey bacon or mushrooms can replace this for a lighter option.
- 1/2 cup sliced green onion: Adds freshness and a pop of color.
How to Make Slow Cooker Colcannon Potatoes | Easy Crockpot Dinner

- Prep the Ingredients: Start by peeling and dicing the 2.5 lbs. of russet potatoes and rough chopping the 1/2 head of cabbage. Place these ingredients into the slow cooker.
- Season the Veggies: Sprinkle the 4 chicken bouillon cubes, 1/2 tsp. of garlic powder, and 1/2 tsp. of onion powder over the potatoes and cabbage mixture.
- Add Water: Pour just enough water to cover the potatoes and most of the cabbage. It’s fine if some cabbage sticks out; just be careful not to overfill your slow cooker.
- Cook: Secure the lid on your slow cooker and turn it to HIGH, cooking for about 4.5 hours, until the potatoes are fork-tender and the cabbage is soft.
- Drain: Once cooked, carefully drain the water from the pot. This step is crucial to ensure your potatoes don’t end up too watery.
- Mix It Up: Pour the melted butter, 1/2 cup of half and half, and season with 3/4 tsp salt and ¼ tsp pepper into the drained potatoes and cabbage.
- Mash: Using a potato masher, mash the mixture until creamy. If it looks a little dry, add a touch more half and half, but don’t go overboard!
- Finish: Once mashed, gently fold in the crumbled bacon and sliced green onion. Stir this all together, and your colcannon potatoes are ready to be served!
Storing & Reheating
Let any leftovers cool to room temperature before transferring them to an airtight container. They can be stored in the refrigerator for up to 5 days. For longer storage, you can freeze them in an airtight container for up to 3 months. When ready to enjoy again, simply reheat in the microwave for 2-3 minutes or warm them in a pot over medium heat, stirring occasionally. Note that the texture might change slightly after freezing, so adding a splash of half and half while reheating can help refresh the dish.
Chef’s Helpful Tips
- To avoid watery potatoes, make sure only to add enough water to cover the vegetables without overfilling.
- For creamier potatoes, ensure your butter is fully melted before you add it to the mixture.
- If you’re crunched for time, you can prep the potatoes and cabbage the night before and store them in the refrigerator until ready to cook.
- For an extra layer of flavor, consider blending in herbs like chives or thyme when mixing.
- Taste as you go! Adjust salt and pepper to suit your preferences.
- If you have leftovers, try using the mashed colcannon as a filling for savory pies or fritters.
