Kale and broccoli soup recipe

Step by Step

Step 1

Heat the oil in a medium saucepan over medium heat. Add the onion and cook, stirring, until tender, 3 to 5 minutes. Add the potato, cayenne, garlic, 1/2 teaspoon salt and a few grinds of pepper and cook, stirring, until the potatoes are well coated, 2 to 3 minutes. Pour in the broth and 1 cup of water and bring to a simmer.

Step 2

Add the broccoli and simmer until the potatoes and broccoli are tender, about 15 minutes, adjusting the heat as needed to maintain a simmer. Stir in the kale and continue to cook until the kale is tender, about 5 minutes. Remove from the heat, and let cool at least 5 minutes. Carefully puree until smooth with a handheld immersion blender or in 2 to 3 batches in a blender (do not fill blender more than halfway full).

Step 3

Reheat the soup if necessary. Off the heat, swirl in the butter until it is melted. Adjust the consistency with water and seasoning with salt and pepper as needed.
