Ingredients and Substitutions
What You’ll Need

- 1 tablespoon olive oil
- 1 medium onion, diced
- 4 cups green cabbage, thinly sliced
- ½ teaspoon dried thyme

Ingredient Tips

How to Make Colcannon Soup
Step-by-Step Instructions
- Cook the potatoes
Add the diced potatoes to a saucepan with salt, pepper, broth, and water. Bring to a boil, then reduce to a simmer for 10 to 15 minutes until tender. - Prepare the vegetables
While the potatoes cook, dice the onion and slice the cabbage thinly. - Blend the potatoes
Once the potatoes are soft, allow them to cool slightly before blending until smooth. Use a regular blender or an immersion blender if you prefer. - Sauté the cabbage
In the same pot, heat olive oil over medium heat. Add the onion and cook for 2 to 3 minutes. Stir in the cabbage and thyme, cooking for 10 minutes until tender. - Combine and finish
