Heat the olive oil in a large skillet over medium heat. Add the sausage and cook until browned and cooked through, breaking it into crumbles as it cooks. Drain off any excess fat.
1 Tbsp olive oil, 1 lb mild Italian sausage
Transfer the sausage to the crockpot. Add the onion, potatoes, garlic, Italian seasoning, salt, pepper, and chicken broth, and stir to combine. Cover and cook on LOW for 4 to 6 hours or on HIGH for 2 to 3 hours, until the potatoes are fork-tender.
1 white onion, 2 lb Yukon gold potatoes, 4 cloves garlic, 1 tsp Italian seasoning, ½ tsp sea salt, ¼ tsp black pepper, 4 cups chicken broth
Using the back of a fork, mash about ⅓ of the potatoes against the side of the crockpot. This thickens the soup without flour or starch.
Stir in the coconut milk and kale. Cover and cook on HIGH for 30 minutes.
13.5 oz coconut milk, 1 cup kale
Stir in the cheese until melted. Taste and adjust the salt, then serve with red pepper flakes if you like some heat.
1 cup shredded cheddar cheese, Red pepper flakes
