In a skillet over medium heat, place the Italian sausage. Cook until browned and crispy, about 5-7 minutes. Drain excess grease if necessary.

Add the diced onion and minced garlic to the skillet. Sauté until the onion is softened and translucent, approximately 3-4 minutes.

Carefully pour the sausage mixture into your crockpot.

Pour in the chicken broth followed by the sliced potatoes. Stir to combine.

Cover the crockpot and set it to cook on low for 6-8 hours, or on high for about 4 hours.

In the last 30 minutes of cooking, stir in the chopped kale and heavy cream.

Before serving, taste and add salt and pepper to your liking.
