Essential Ingredients for Your Cauliflower Colcannon
Crafting this flavorful and healthy cauliflower colcannon relies on a few key ingredients. Here’s what you’ll need and some tips for choosing the best:
- Cauliflower: The star of our low-carb show! For the best flavor and texture, aim for a large, firm head of fresh cauliflower, weighing approximately 2 pounds. Alternatively, for convenience, you can use about 24 ounces of pre-bagged cauliflower florets. Fresh cauliflower generally offers a superior taste and texture when pureed.
- Kale: To add vibrant color, a slight peppery bite, and a wealth of nutrients, Tuscan or Lacinato kale is highly recommended. Look for bunches with larger, flatter, dark green leaves that are crisp and free from yellowing. Its sturdy texture holds up well to cooking and pureeing.
- Onions: Green onions, also known as scallions, are preferred for their milder flavor and delicate crunch. They provide a fresh aromatic base without overpowering the other ingredients. Both the white and green parts will be used.
- Garlic: Fresh garlic cloves are indispensable for their pungent, aromatic flavor. Pick up a whole head of fresh garlic, or for a quicker option, a tube of garlic puree works in a pinch. However, fresh is always best for maximum impact.
- Milk: For creamy richness, half and half is an excellent choice. If you’re aiming for a dairy-free or vegan version, full-fat canned coconut milk is a fantastic substitute. It provides a similar luscious texture and a subtle, pleasant sweetness that complements the cauliflower beautifully.
- Butter: Unsalted grass-fed butter is recommended for its superior flavor and nutritional profile. For those with dairy sensitivities or following a stricter diet, clarified butter (or ghee) or a good quality plant-based butter are excellent alternatives.
Remember to consult the comprehensive recipe card below for exact measurements of all ingredients, including salt and pepper.

Customizing Your Cauliflower Colcannon: Substitutions and Variations
One of the beauties of this cauliflower colcannon recipe is its adaptability. Feel free to experiment with these suggestions to tailor it to your taste preferences and dietary needs:
- Kale Alternatives: If kale isn’t your favorite, or you simply prefer a milder green, baby spinach is an excellent substitute. It wilts down quickly and adds a delicate flavor. You could also try Swiss chard or regular green cabbage for a more traditional colcannon feel.
- Boost the Creaminess: For an extra rich and indulgent colcannon, swap out the half and half or coconut milk for dairy heavy cream. This will enhance the luxurious texture and mouthfeel.
- Dairy-Free and Vegan Options: Easily make this recipe dairy-free by using plant-based butter (such as almond or cashew butter) or high-quality extra virgin olive oil in place of dairy butter. As mentioned, canned full-fat coconut milk is a superb dairy-free liquid option.
- Enhance Savory Flavor: Don’t be shy with aromatics! You can always add an extra clove or two of minced garlic or incorporate more chopped green onions during the sautéing process to layer in more savory depth. A pinch of freshly grated nutmeg also pairs beautifully with creamy vegetable dishes.
- Herbaceous Notes: Fresh herbs can elevate the dish. Consider adding a tablespoon of chopped chives, parsley, or even a sprig of fresh thyme or rosemary to the sautéed greens for an aromatic boost.
- A Touch of Cheese: While not traditionally Irish, a sprinkle of freshly grated Parmesan or white cheddar cheese stirred into the colcannon at the end, or sprinkled on top before serving, adds a delicious, salty, umami kick.
Chef’s Tip: Clarified Butter & Ghee Explained
Clarified Butter is a wonderful ingredient, especially for those with dairy sensitivities. It is made by gently heating unsalted butter until its milk solids (proteins like casein and whey) separate from the golden butterfat. These milk solids are then carefully skimmed off or strained out. The resulting clarified butter has a clean, mild butter flavor and, crucially, a significantly higher smoke point than regular butter, making it ideal for higher-heat cooking methods without burning. Many individuals who are sensitive to dairy often tolerate clarified butter (and ghee, which is cooked slightly longer to achieve a nuttier flavor and even more intense removal of milk solids) because the primary culprits for intolerance – lactose and casein – have been removed during the clarifying process. While store-bought options are available, making your own is simple and rewarding. Here’s how you can make homemade clarified butter or ghee for this recipe and many others.
Step-by-Step Cauliflower Colcannon Instructions
Creating this delicious cauliflower colcannon is straightforward. Follow these steps for a creamy and flavorful result:
First, prepare your vegetables. For the cauliflower, carefully trim the entire head, breaking it down into florets of roughly equal size. Discard the tough center stem. While bagged florets can be used in a pinch (around 24 ounces), preparing fresh cauliflower yourself often yields a fresher taste and better texture. For the kale, strip the tough center stems from the leaves using your hands, then gather the leaves and chop them into small, manageable pieces. Finally, finely chop your green onions, reserving a few green tops for a fresh garnish at the end.
Serving & Storing Your Cauliflower Colcannon
To fully enjoy the creamy texture and rich flavors of your cauliflower colcannon, serving it hot is key. Cauliflower puree, much like mashed potatoes, can lose its warmth quickly. For optimal enjoyment, consider mixing the colcannon and then placing the serving bowl in a warm oven (around 200°F or 95°C) for a few minutes before serving, or simply reheat it in the microwave until piping hot.
Make-Ahead & Storage: This cauliflower colcannon is an excellent dish for meal prepping. You can prepare the entire dish in advance and store it in an airtight container in the refrigerator for up to 4 days. When you’re ready to serve, reheat it thoroughly. For a microwave oven, heat in 1-2 minute intervals, stirring between each, until it reaches a safe internal temperature of 165°F (74°C). If reheating in a conventional oven, place it in an oven-safe dish, cover loosely with foil, and bake at 350°F (175°C) until heated through, which may take longer if it’s very cold straight from the refrigerator.
Serving Enhancements: While not traditionally Irish, a touch of freshly grated Parmesan cheese stirred into the colcannon before serving can add a wonderful salty, umami depth that many enjoy. Alternatively, a final swirl of melted butter or a drizzle of good olive oil just before serving adds a lovely sheen and boosts the flavor. Garnish with those reserved chopped green onion tops for a pop of color and fresh onion flavor.
This colcannon pairs beautifully with a variety of main courses, from classic corned beef and roast chicken to pan-seared salmon or even a hearty vegetarian stew. Its comforting nature makes it a versatile side for almost any meal.
Frequently Asked Questions About Cauliflower Colcannon
Traditional Irish colcannon is a beloved and hearty dish, typically made with creamy mashed potatoes, generously mixed with either finely chopped kale or green cabbage.

This cauliflower colcannon recipe is naturally gluten-free, making it a fantastic option for those with gluten sensitivities or celiac disease.

Cauliflower colcannon is a wonderfully versatile side dish that complements a wide array of main courses. It’s particularly delicious when served with savory meat dishes such as traditional corned beef and cabbage, succulent roast chicken, tender lamb chops, or even pan-seared pork loin. It also makes a fantastic accompaniment to roast salmon or other flaky white fish. For a vegetarian meal, pair it with hearty mushroom steaks or a rich lentil loaf. Garnish with a pat of butter melting in the center and a sprinkle of fresh green onion tops for a classic presentation.
Yes, you can absolutely use frozen cauliflower florets for convenience. There’s no need to thaw them beforehand; simply steam them directly from frozen. Just be aware that frozen cauliflower can sometimes retain more water, so you might need to steam them for a minute or two longer until they are very tender, and then drain them exceptionally well before pureeing to prevent a watery colcannon.
For an even creamier texture, ensure your cauliflower is steamed until it’s exceptionally tender – almost falling apart. When pureeing, you can add an extra tablespoon of butter or a splash more milk/cream. Using a food processor ensures a super smooth consistency. Additionally, warming your milk or cream slightly before adding it can help create a silkier puree.

📖 Recipe
Cauliflower Colcannon
Sally CameronEquipment
- Food Processor
- Steamer Basket
- Large Pot (5 quarts)
- Medium Sauté Pan
Ingredients
- 1 head cauliflower (approx. 2 pounds, or 24 ounces bagged florets)
- 1 bunch Tuscan or Lacinato kale
- 3 green onions or scallions
- 4 large garlic cloves (peeled)
- ¾ cup canned coconut milk (or half and half)
- 2-3 tablespoons unsalted grass-fed butter, ghee, or plant butter (divided use)
- ¼ teaspoon sea salt (or to taste)
- ¼ teaspoon ground pepper (preferably white, or to taste)
Instructions
- Begin by preparing your vegetables. Trim the large head of cauliflower into small, uniform florets, discarding the tough center stem. For the kale, strip the leaves from the tough central stems by hand, then gather the leaves and finely chop them into small pieces. Finely chop the green onions, setting aside a few of the vibrant green tops to use as a garnish later.
- Next, steam the cauliflower and garlic. Fill a large pot (approximately 5 quarts) with about 1-2 inches of water, place a steamer rack inside, and cover with a lid. Bring the water to a rolling boil over medium-high heat until steam is vigorously escaping. Carefully place the cauliflower florets and peeled garlic cloves into the steamer rack. Steam them until they are very tender and easily pierced with a fork, which typically takes 8-10 minutes. While the cauliflower is steaming, melt 1 tablespoon of butter (or your chosen alternative) in a medium sauté pan over medium heat. Add the chopped green onions (reserving a few tops) and the chopped kale. Sauté, stirring occasionally, until the kale has softened and wilted, about 4 minutes.
- Once steamed, carefully drain the cauliflower florets and garlic cloves, ensuring all excess water is removed. Transfer them to the bowl of a food processor fitted with a steel blade. Add the coconut milk (or half and half) and 1 tablespoon of butter (or alternative). Puree until the mixture is fairly smooth and creamy. If you prefer a more rustic texture, you can stop processing a bit sooner.
- Transfer the cauliflower puree to a large mixing bowl. Add the sautéed kale and green onions, then stir everything together until well combined. Season generously with salt and pepper to taste. If the colcannon has cooled significantly, gently reheat it in the microwave or place it in a warm oven for a few minutes while you finish preparing your meal. For an even richer flavor and creamy finish, stir in an additional tablespoon of butter just before serving. If you desire a more refined and uniform texture with the kale, you can add the sautéed kale to the food processor with the cauliflower puree and pulse a few times to finely chop and integrate it. Serve hot and garnish with the reserved green onion tops.
Notes
Variations:
- Don’t like kale? Swap baby spinach for a milder, quicker-cooking green, or use traditional green cabbage.
- For a richer indulgence, use dairy heavy cream instead of coconut milk or half and half.
- To make it dairy-free or vegan, use plant-based butter or extra virgin olive oil in place of dairy butter.
- Enhance the savory flavor by adding more garlic and green onions, or a pinch of freshly grated nutmeg.
