Caldo Verde, which translates to “Green Broth,” is a beloved Portuguese soup built on a simple, comforting foundation: tender starchy vegetables, thinly sliced cured sausage and a generous handful of shredded leafy greens. The result is a warm, nourishing bowl that feels both rustic and refined, and it comes together with surprisingly few ingredients and straightforward technique.
This version respects the spirit of classic Caldo Verde while adapting the recipe so it works for Whole30 and Paleo-style eating. Instead of the more common yellow potatoes, Japanese yams (or other white-fleshed sweet potatoes) provide a lower-glycemic alternative without losing the creamy texture. If traditional Portuguese chouriço is hard to find without added sugars or fillers, a quality Spanish-style cured chorizo is a fine substitute; peel away the casing and slice the sausage as thinly as possible so its oils and seasonings integrate into the broth. A small spoonful of smoked paprika enhances that smoky profile and gives the broth a warm, golden hue. For the greens, collards are the classic and my personal favourite, though kale is an excellent and accessible alternative.
What You Need For Whole30 Caldo Verde
- Japanese yams (or white-fleshed sweet potatoes): These give the soup a silky, velvety body when pureed. You can substitute yellow potatoes if you prefer a more traditional texture, or use cauliflower for a lower-carb option. Choose firm tubers with no soft spots.
- Cured sausage: Use a sugar-free, preservative-free cured sausage when possible. Spanish-style chorizo, Portuguese chouriço or linguiça all work well—just remove the casing and slice the sausage very thin so it releases flavour evenly into the soup.
- Collard greens or kale: Collards are traditional and offer a slightly milder, buttery texture when shredded finely. Remove stems and ribs, then slice the leaves into very thin ribbons so they soften quickly in the hot broth.
- White onion: A large white onion lends a touch of sweetness and balances the smokiness of the sausage. Slice it so it softens and blends smoothly when pureed.
- Garlic: A few cloves add depth; they get blended with the broth so there’s no need to mince them finely.
- Chicken stock and water: A mixture of good-quality chicken stock and water yields the best flavour without overpowering the other ingredients. Because this soup relies on only a handful of components, using a high-quality stock—homemade if possible—makes a noticeable difference.
- Smoked paprika (optional): A tablespoon enhances the smoky notes and complements the sausage. It alters the colour slightly but deepens the overall flavour.
- Olive oil, salt and freshly cracked black pepper: Basic seasonings finish the soup. Taste and adjust seasoning after the greens and sausage have softened.
Small technique notes: sweat the onions gently in olive oil until soft and translucent—this builds a mellow base. After simmering and blending the yams, the soup should be smooth and slightly thick; add stock or water to reach your preferred consistency. Adding the greens and sausage at the end maintains texture and prevents the collards from overcooking. Serve piping hot with the lightly softened greens and slices of sausage distributed throughout each bowl.
Caldo Verde – Whole30, Paleo
15 minutes
35 minutes
50 minutes
6 servings
Ingredients
- 2 tablespoons extra virgin olive oil
- 1 large white onion, sliced
- Kosher salt, to taste
- 3 cloves garlic, roughly chopped
- 1 tablespoon smoked paprika (optional)
- 1 quart chicken stock
- 3 medium Japanese yams (or yellow potatoes / white-fleshed sweet potatoes)
- 1.5 quarts water
- 1 pound collard greens, stems removed and leaves very thinly sliced
- 8 ounces cured chorizo sausage, casing removed and very thinly sliced (or chouriço / linguiça)
- Freshly cracked black pepper, to taste
Instructions
- Preheat a large stockpot over medium heat. Add the olive oil and heat until shimmering. Add the sliced onion and a pinch of salt. Cook, stirring occasionally, until the onion is soft and translucent, about 10 minutes.
- Add the chopped garlic and cook, stirring, for about 60 seconds. If using, stir in the smoked paprika and cook for another minute to bloom the spice.
- Add the chicken stock, the peeled and chopped yams, and enough water to cover the vegetables. Increase the heat to high, bring to a steady simmer, then cover and cook until the yams are fork-tender, about 10 minutes.
- Remove the pot from the heat. Using an immersion blender (or a regular blender in batches), puree the soup until completely smooth and velvety. If the soup is too thick, add additional water or stock a little at a time to reach your desired consistency.
- Return the pot to a gentle simmer, then add the thinly sliced collard greens and the sliced chorizo. Cook, stirring occasionally, until the greens are just tender and the sausage has warmed through, about 8 minutes.
- Taste and adjust seasoning with salt and freshly cracked black pepper. Serve immediately while hot, making sure each bowl has a balance of creamy broth, greens and sausage slices.
