I was trying to use up a ham shank and honor my New Year’s resolution to eat low-carb. The result is a yummy and hearty winter soup, chock-full of rich, smoky flavor and chunks of veggies and ham. You won’t even miss the carbs!
Heat olive oil over medium heat in a large soup pot. Add onion and celery; saute until onion begins to soften, 3 to 4 minutes. Add garlic and saute until fragrant, about 1 minute. Transfer onion mixture to a bowl.
Add broth and ham shank to the same pot and bring to a boil. Reduce heat to low, cover, and simmer until ham is tender and falling off the bone, about 1 hour. Transfer ham and bone to a plate. Chop ham when cool enough to handle. Discard bone.
Add onion mixture to the broth, along with 1/2 of the sweet potato, 1/2 of the cauliflower, and bay leaf. Bring to a boil, then reduce heat to medium and cook until vegetables are tender, about 10 minutes. Remove from heat, discard bay leaf, and use emulsion blender to blend until smooth.
Add remaining potatoes and cauliflower and bring to a simmer. Cook until vegetables are tender, 10 to 15 minutes. Add ham, liquid smoke, salt, and pepper. Ladle into bowls and garnish with parsley.
