How to Make Slow Cooker Colcannon Potatoes | Easy Crockpot Dinner

- Prepare the Base: In your slow cooker, add the peeled and diced 2.5 lbs. russet potatoes along with the chopped 1/2 head cabbage. Toss in the 4 chicken bouillon cubes, 1/2 tsp. garlic powder, and 1/2 tsp. onion powder.
- Add Water: Pour in enough water to cover the potatoes and most of the cabbage. Don’t fill it too high to avoid overflow during cooking.
- Cook: Cover with the lid and set your slow cooker to HIGH. Let it cook for 4.5 hours, until the potatoes are fork-tender and the cabbage is soft.
- Drain: Once cooked, carefully drain the water from the pot.
- Mix in Creaminess: Pour in the melted 1/2 cup salted butter, 1/2 cup half-and-half, 3/4 tsp. salt, and 1/4 tsp. pepper. Stir to combine all the flavors beautifully.
- Mash: Using a potato masher, mash the mixture until you achieve your desired level of creaminess. If the mixture looks dry, add a splash more half-and-half.
- Finish: Stir in the crumbled bacon and sliced 1/2 cup green onion. Mix well and serve warm for everyone to enjoy!
Storing & Reheating
To store any leftover Slow Cooker Colcannon Potatoes, allow them to cool at room temperature for about an hour, then transfer to an airtight container. They will keep well in the refrigerator for up to 3-4 days. If you wish to freeze the leftovers, place them in a freezer-safe container, where they can be kept for about three months. To reheat, simply warm them in the microwave or on the stovetop over low heat, adding a little splash of milk or half-and-half to revive their creamy texture.
Chef’s Helpful Tips
- Be cautious not to overfill your slow cooker; it should be about two-thirds full after adding water.
- If you notice the potatoes appear even slightly dry while mashing, don’t hesitate to add a bit more cream—just go easy on it!
- Make sure the bacon is crispy before adding to the mixture; this ensures that you get the perfect texture and flavor contrast.
- For a lighter version, consider cutting down on the butter or substituting with olive oil.
There’s something special about a warm dish that brings family and friends together. Slow Cooker Colcannon Potatoes are not just a meal; they embody comfort and nostalgia, inviting you to savor each bite. Don’t shy away from adding your own twist—try incorporating different spices or herbs. I hope you enjoy making this dish as much as I do!
