A creamy, flavorful low-carb twist on traditional Irish colcannon using cauliflower mash and sautéed greens, perfect for cozy dinners and quick meals.

Ingredients

Scale
  • 1 large head of cauliflower (about 2 pounds / 900 g), cut into florets
  • 3 tablespoons unsalted butter, softened
  • 1/4 cup heavy cream (or full-fat coconut cream for dairy-free version)
  • Salt and freshly ground black pepper, to taste
  • 3 cups kale, stems removed and chopped (spinach or Swiss chard can be used as alternatives)
  • 4 green onions, thinly sliced (white and green parts separated)
  • 2 cloves garlic, minced
  • 1 tablespoon olive oil or butter, for sautéing
  • Pinch of freshly grated nutmeg (optional)

Instructions

  1. Rinse and cut the cauliflower into even-sized florets. Place the florets in a steamer basket over boiling water, cover, and steam for about 12–15 minutes until very tender when pierced with a fork. Alternatively, simmer in salted water for 10–12 minutes, then drain well.
  2. While the cauliflower steams, heat olive oil or butter in a large skillet over medium heat. Add the white parts of the sliced green onions and minced garlic. Sauté for 1–2 minutes until fragrant but not browned.
  3. Add the chopped kale to the skillet and cook, stirring occasionally, for about 5–7 minutes until wilted and tender but still vibrant green. Season with a pinch of salt, pepper, and nutmeg if using. Remove from heat and set aside.
  4. Transfer the steamed cauliflower to a large bowl. Add the softened butter and heavy cream. Using a potato masher or immersion blender, mash until smooth and creamy. Season with salt and pepper to taste. Avoid overworking the mash to prevent it from becoming gluey.
  5. Gently fold the sautéed greens and green onion tops into the creamy cauliflower mash. Taste and adjust seasoning as needed.
  6. Serve warm, optionally with an extra pat of butter on top.

Notes

Drain cauliflower thoroughly to avoid watery mash. Use good-quality butter and cream for best flavor. Avoid overblending cauliflower to prevent gluey texture. A squeeze of fresh lemon juice can brighten the greens if they taste bitter. For dairy-free, substitute butter with vegan margarine or olive oil and heavy cream with coconut cream or plant-based milk.
