Ingredients

  • 2 pounds rutabaga about 3 medium sized
  • 5 tablespoons butter divided
  • 2 cups kale shredded - about 4 large leaves
  • 1 teaspoon salt plus a pinch
  • ½ teaspoon black pepper
  • 2 tablespoons heavy whipping cream
  • 2 green onions green part only for low FODMAP

Instructions

Prepare the rutabaga

  • Cut off the top and bottom and peel the rutabaga with a vegetable peeler.
  • Chop the rutabaga into ½-¾ inch cubes.

Boiling cook method

  • Add the rutabaga cubes to a stock pot and add enough water to cover.  Add a pinch of salt.
  • Bring to a boil and boil for about 20 minutes, or until fork tender.  Drain.

Pressure cooking method

  • Add chopped rutabagas to your pressure cooker and cook at high pressure for 10 minutes.  Use the natural release or quick release method. Either is fine.

Steaming cook method

  • Add the chopped rutabaga to your vegetable steamer and steam for about 25 minutes or until soft.

Prepare the kale

  • Wash the kale, remove the stems and chop or tear into small pieces.
  • Sauté in 2 tablespoons of butter until soft, about 5 minutes

Combine and serve

  • In a large bowl, mash the cooked rutabaga with the remaining butter, salt, pepper, kale, cream and green onion.
  • Transfer colcannon to a serving bowl and top with more butter (if desired) and garnish with more chopped green onion (optional)

Notes

Note on cooking time:  Cooking time is based on cooking the rutabaga in a pressure cooker.

Variations and add-ins

  • Finely diced ham or crumbled sausage – mix in for decadent salty goodness
  • Sautéed leek – thinly slice about half of a leek (green part only for low-FODMAP), sauté in butter or olive oil until soft and stir in
  • Replace the butter – with ghee
  • Garlic or garlic-infused olive oil – sauté some garlic or add some garlic-infused olive oil, which is a flavorful low-FODMAP option
  • Cheese – who loves cheesy mashed potatoes?  Stir in some of your favorite shredded cheese or blue cheese to the hot colcannon.
  • Add some spices – thymesavory, a pinch of nutmeg or mace powdered sage or fresh sage sautéed in butter until crisp
  • Sour cream – adds extra creaminess and bit of tang
  • Make colcannon cakes – form into patties and fry in butter, oil or bacon grease until crisp
  • Paleo and vegan colcannon – simply replace the butter with your favorite butter alternative and use coconut cream or nut cream to add a creamy texture
