Ingredients You’ll Need

- 1/2 head cabbage: Roughly chopped; it adds a delightful crunch and flavor that balances the creaminess of the potatoes.
- 4 chicken bouillon cubes: These provide a savory depth, infusing the potatoes with rich flavor as they cook.
- 1/2 tsp. garlic powder: An easy way to enhance the flavor profile without the fuss of peeling and chopping fresh garlic.

- Water to cover: Adds moisture and steam as your slow cooker works its magic, creating tender potatoes and cabbage.
- 1/2 cup half and half: This creamy addition ensures a smooth texture; milk can work in a pinch if you don’t have half and half on hand.
- 1/2 cup salted butter: Melted butter makes everything better, adding richness to this comforting dish.
- 3/4 tsp. salt: Seasoning is key for flavor; always taste as you go!

How to Make Slow Cooker Colcannon Potatoes | Easy Crockpot Dinner

- Prep the Potatoes and Cabbage: Add the peeled and diced russet potatoes along with the roughly chopped cabbage to your slow cooker. Sprinkle in the chicken bouillon cubes, garlic powder, and onion powder for robust flavor.
- Add Water: Pour in just enough water to cover the potatoes and most of the cabbage. It’s okay if some of the cabbage stays above the water. Be cautious not to overfill your slow cooker to prevent overflow during cooking.
- Cook It Up: Secure the lid on your slow cooker. Set it to cook on HIGH for about 4.5 hours. You might want to stir occasionally for even cooking.
- Drain the Cooking Liquid: Once the cooking time is up, carefully drain any leftover water off the potatoes and cabbage. This step ensures your colcannon won’t end up too soupy.
- Add Creamy Goodness: Pour melted butter and half and half over the drained potatoes and cabbage. Sprinkle in the salt and pepper.
- Mash Away: Using a potato masher, mash everything together until smooth and creamy. If it looks a bit dry, add a touch more half and half—but don’t go overboard.
- Fold in Your Toppings: After mashing, gently fold in the crumbled bacon and sliced green onions for an alluring finishing touch before serving.
Storing & Reheating
Store any leftover Slow Cooker Colcannon Potatoes in an airtight container at room temperature for up to a few hours. If you need to store them long-term, pop them in the refrigerator, where they’ll stay fresh for about 3–5 days. To enjoy later, you can freeze them for up to 3 months. When reheating, warm them in the microwave or on the stovetop until heated through, making sure to stir in a bit of additional half and half or butter if they seem dry.
Chef’s Helpful Tips
- To avoid any unpleasant textures, ensure potatoes are uniformly diced to cook evenly.
- You can prep the potatoes and cabbage the night before if you want to save time; just chop and store them in water to prevent browning.
- Timing is key — check for doneness with a fork at the end of the cooking time. If they aren’t quite tender, let them cook a little longer.
- Experiment with flavor by adding extras! Try mixing in sour cream or a flavorful cheese like cheddar if you desire a cheesier twist.
Slow Cooker Colcannon Potatoes brings joy and warmth to any table, making it an absolute must for both weeknight dinners and special occasions. I love how these bold flavors come together, blending tradition with ease. The versatility and comfort of this recipe mean you can enjoy it no matter the season.

Certainly! You can prepare the entire dish and store it in the refrigerator. Reheat gently before serving, adding in a little cream or butter to bring back that creamy texture.
