The Delicious Evolution: From Traditional to Keto Colcannon
Colcannon, in its traditional form, is a quintessential Irish side dish made from creamy mashed potatoes, enhanced with a healthy blend of kale or cabbage and fresh green onions. It’s a culinary stroke of genius, offering two comforting side dishes harmoniously combined in one bowl. This concept of blending creamy mash with vibrant greens is what makes Colcannon such a timeless favorite.
For those following a low-carb or ketogenic lifestyle, recreating this Irish classic is surprisingly simple and equally satisfying. Our Keto Colcannon recipe achieves the same rich and creamy texture by utilizing puréed cauliflower mash, then stirring in perfectly sautéed greens. The result is a dish that mimics the heartiness of the original without the added carbohydrates, making it a guilt-free indulgence.
This versatile dish pairs beautifully with a variety of main courses. Serve it alongside classic corned beef, tender ham, or even top it with a fried egg for a complete and utterly satisfying Irish-themed meal. Its adaptability means it can elevate any dinner, transforming a simple meal into something special.

Key Ingredients and Creative Variations for Your Colcannon
This Mashed Cauliflower Colcannon recipe is designed to be vegetarian-friendly, offering a nutritious and satisfying option for everyone. For those desiring a vegan Colcannon, we’ve included recommended plant-based options below, ensuring flexibility for all dietary preferences.
- Cauliflower Florets: The star of our low-carb mash. You can use either frozen or fresh cauliflower. For frozen, a 30-ounce bag is typically sufficient. If using fresh, approximately 2 medium heads of cauliflower will yield the right amount. Fresh cauliflower offers a slightly more vibrant flavor, while frozen offers ultimate convenience.
- Butter: Essential for that rich, creamy texture and classic flavor. Use high-quality dairy butter, or opt for a plant-based butter alternative to make the dish vegan.
- Milk of Choice: We recommend whole milk for its richness, but heavy cream or half-and-half can be used for an even more decadent consistency. For a plant-based version, unsweetened soy milk or almond milk work beautifully, adding creaminess without dairy.
- Kale: The healthy green component. Ensure woody stems are removed, and the leaves are torn into bite-sized pieces. Curly kale, Lacinato (dinosaur) kale, or tender baby kale are all excellent choices, each offering a slightly different texture and mild bitterness that complements the creamy cauliflower.
- Green Onions (Scallions): These provide a mild onion flavor and a touch of freshness. Use both the white and green parts, reserving some of the vibrant green tops for garnish. As an alternative, thinly sliced leeks can be used for a slightly sweeter, milder onion note.
- Olive Oil: Used for sautéing the kale and softening the onions and garlic, imparting a subtle fruity depth to the greens.
- Garlic Cloves: While optional, fresh minced or pressed garlic adds a wonderful aromatic depth and savory kick that truly elevates the flavor profile of the dish.
You’ll also need basic seasonings like salt and freshly ground black pepper. Start with a minimal amount and adjust to your taste preferences upon serving, as different ingredients can vary in their natural sodium content.
Tasty Variation: For an extra layer of savory flavor and satisfying crunch, garnish your Cauliflower Colcannon with crumbled crispy bacon. It’s a delightful addition that perfectly complements the creamy texture and earthy greens.

Step-by-Step Directions to Create Your Keto Cauliflower Colcannon
Crafting this keto-friendly Cauliflower Colcannon involves two simple stages: first, creating a velvety mashed cauliflower base, and then expertly integrating the flavorful kale and green onion mixture. The visual guides below will walk you through each step.
- Prepare the Cauliflower: Begin by cooking your cauliflower florets until they are very tender. If using frozen cauliflower, simply follow the package instructions, typically steaming in the microwave or boiling on the stovetop. For fresh cauliflower, bring a large pot of salted water to a rolling boil and cook the florets for about 6-7 minutes, or until they can be easily pierced with a fork. Drain thoroughly, ensuring no excess water remains, as this can make your mash watery.
- Pro Tip: While the cauliflower is cooking, use this time efficiently to prepare your kale and chop the green onions. This multitasking approach will significantly speed up your overall cooking time.
- Create the Mash: Transfer the cooked and drained cauliflower to a large, sturdy pot. Add your chosen milk, softened butter, salt, and pepper. Use an immersion blender directly in the pot to purée the mixture until it’s wonderfully smooth and creamy.
- Alternative Method: If you don’t have an immersion blender, you can process the cooked cauliflower in a food processor. Pulse in short bursts until you achieve your desired mashed consistency. Be careful not to over-process, as it can sometimes become too liquidy.
- Adjust Consistency (if needed): Stir the mashed cauliflower thoroughly. If you desire an even creamier consistency, feel free to add a little more butter, milk, or even some vegetable broth. If you boiled fresh cauliflower, you could also use a small amount of the reserved cooking liquid. Once satisfied, temporarily transfer the mashed cauliflower to a separate serving dish to free up your pot.
- Sauté the Aromatics and Greens: Return the now-empty pot to medium heat. Add the olive oil. Once shimmering, add the chopped green onions (reserving some for garnish) and the minced garlic (if using). Sauté for 1-2 minutes until fragrant.
- Wilt the Kale: Add the prepared kale to the pot. Sauté for approximately 5 minutes, stirring occasionally, until the kale is completely wilted and tender, and the green onions are softened. The vibrant green color of the kale should deepen slightly.
- Combine and Serve: Return the mashed cauliflower to the pot with the sautéed greens. Stir all the ingredients together thoroughly until they are well combined and the kale is evenly distributed throughout the creamy mash.
- Final Touches: Garnish generously with the reserved chopped green onions for a pop of color and fresh flavor. Taste and adjust seasoning with additional salt and pepper as needed. Serve warm and enjoy!
Shortcut to Speed: Make It Even Faster!
For those days when time is truly of the essence, here’s a brilliant shortcut: start with a box of pre-made frozen mashed cauliflower from your grocery store’s freezer aisle. Cook it according to the package directions, and then simply pick up from step 4 in our recipe (sautéing the greens) to transform it into a quick and delicious Cauliflower Colcannon. This simple hack ensures a wholesome meal is never out of reach, even on your busiest days.
Storage and Reheating Made Easy
One of the many benefits of Cauliflower Colcannon is how well it stores, making it perfect for meal prepping or enjoying leftovers:
- To Store: Place any leftover Cauliflower Colcannon in an airtight storage container. It will keep beautifully in the refrigerator for up to 3 days, maintaining its creamy texture and rich flavor.
- To Reheat: For best results, gently warm leftovers in a pot over medium heat on the stovetop, stirring occasionally until heated through. Alternatively, you can reheat individual portions in the microwave; it typically takes only a few minutes until warm and ready to enjoy.
- To Freeze: This dish freezes exceptionally well. Allow the Colcannon to cool completely, then transfer it to an airtight, freezer-safe storage container. It can be stored in the freezer for up to 3 months. To reheat from frozen, you can microwave it directly, or for a more gradual thaw, defrost it overnight in the refrigerator before warming.
