Remove the stems from the kale and cut the leaves into chunks, wash and dry the kale leaves. Set aside to dry
Heat oil over medium-high heat in a Dutch oven. Add the onion, garlic, and kosher salt. Sauté for 5 minutes, stirring until translucent and soft. Be careful not to burn the garlic.
Add hot curry powder and red curry paste to the pot and stir for 15 to 30 seconds until fragrant.
Add diced tomatoes, broth of choice, and chickpeas to the soup pot. Stir and scrape the bottom of the pot and bring to a boil.
Reduce to a simmer, cover. Simmer for 15 minutes.
Add coconut milk and simmer for another 5 minutes to meld the flavors together.
Add the kale and cook until wilted, about 3 minutes, and then serve hot.
Notes
Use full-fat coconut milk: It creates a creamier, more luxurious texture. Let it sit before serving: The flavors deepen as it rests. Add kale last: This preserves color, texture and nutrients. Make it ahead: The stew stores well and reheats beautifully.
