Begin by heating a large pot over medium heat. Once hot, add the Italian sausage, breaking it up with a wooden spoon. Cook for about 5–7 minutes until browned.

Next, add the chopped onion to the pot, cooking for around 3–4 minutes until soft and translucent. Stir in minced garlic and cook for an additional minute.

Pour in the chicken broth, scraping the bottom of the pot to release flavorful bits. Add diced potatoes and raise heat slightly to bring to a gentle boil, which takes about 5 minutes.

Reduce heat to low and let simmer uncovered for 15–20 minutes until potatoes are fork-tender.

Stir in the heavy cream and kale or spinach, letting it simmer gently for another 3–5 minutes until the greens have wilted.

Taste and adjust seasoning with salt, pepper, and red pepper flakes if desired. Serve hot, inviting everyone to enjoy this warm meal.
