Begin by gathering all your ingredients for the Hearty Sausage Soup. Dice the potatoes into even cubes, chop the kale and parsley, and slice the sausage into rounds.

Heat a large soup pot over medium-high heat and add the sliced smoked sausage. Sear for about 5-7 minutes until browned, then transfer to a plate.

In the same pot, add olive oil if needed, then sauté onions with Italian seasoning, black pepper, and white pepper for 4-5 minutes until softened. Add minced garlic and cook for another minute.

Stir in the diced potatoes and pour in the chicken stock, bringing to a gentle simmer. Cook partially covered for about 12 minutes until the potatoes are tender.

Incorporate the navy beans into the pot, stirring gently. Simmer for an additional 10 minutes.

Remove from heat and stir in chopped kale and parsley. Drizzle with lemon juice.

Ladle the soup into warm bowls and serve hot, preferably with crusty bread.
