How to Make Slow Cooker Colcannon Potatoes | Easy Crockpot Dinner

Prepare the Ingredients: Start by peeling and dicing the russet potatoes. Chop your cabbage roughly. This only takes a few minutes and adds to the comforting heartiness of the colcannon.
Combine in the Slow Cooker: Place the diced potatoes and chopped cabbage into your slow cooker. Sprinkle in the chicken bouillon cubes, garlic powder, and onion powder for flavor.
Add Water: Pour in just enough water to cover the potatoes and most of the cabbage. It’s fine if some cabbage remains above water. Avoid overfilling your slow cooker to prevent spills later.
Cover and Cook: Secure the lid on your slow cooker and set it to HIGH for about 4.5 hours. The magic happens here, as the veggies break down beautifully.
Drain & Prepare for Mashing: Once the cooking time is up, carefully drain the excess water from the potatoes and cabbage. You’ll want them a bit moist but not watery.
Mix in Creamy Ingredients: Pour the melted butter and half and half over the drained potatoes and cabbage, followed by the salt and pepper.
Mash It Up: Using a potato masher, gently mash the potatoes until creamy. If they look a bit dry, don’t hesitate to add a touch more half and half.
Fold In Tasty Additions: Finally, fold in the crumbled bacon and sliced green onions to enhance the flavor profile.
Serve and Enjoy: Scoop the colcannon onto plates and serve warm. Enjoy the comforting, savory delight!
Storing & Reheating
Store any leftovers in an airtight container at room temperature for up to two hours after serving. Refrigerate for up to four days, ensuring they are cooled completely before sealing. If you want to save them longer, freeze in a well-sealed container for up to three months. To reheat, simply thaw in the refrigerator overnight and warm in the microwave or on the stovetop. You may find the texture varies a bit after freezing, but a splash of half and half can rejuvenate its creaminess.
Chef’s Helpful Tips
- Watch the Water: Keeping the water level just right prevents a soggy result. Make sure it covers but doesn’t overflow.
- Room Temperature Ingredients: Let butter and half and half sit out for a bit to reach room temperature; it helps them blend seamlessly.
- Timing Is Key: Don’t rush the mashing! Take your time for the perfect creamy texture.
- Flavor Boosting: Consider adding herbs like thyme or rosemary for an aromatic twist.
- Make Ahead: Prepare the veggies the night before and keep them in the fridge, so they’re ready to go when you want to cook.
These Slow Cooker Colcannon Potatoes will surely become a staple in your home. The comforting combination of flavors calls for repeated enjoyment, especially as seasons change and comfort food cravings arise. Don’t hesitate to adapt the ingredients to suit your tastes or dietary needs, and have fun experimenting with different flavors and textures. You’ll invite warmth and smiles around your dinner table every time you serve this dish, filling your loved ones with joy.
