Sauté the Sausage and Veggies:
In a large soup pot or Dutch oven, heat olive oil over medium heat. Add sliced sausage and cook until browned. Add onion, bell pepper, celery, and garlic. Cook for 5–6 minutes until vegetables are softened.
Make the Base:
Sprinkle flour over the sausage and veggies. Stir and cook for 1–2 minutes to form a roux. Slowly add in the chicken broth while stirring.
Add Potatoes and Corn:
Stir in potatoes, corn, Cajun seasoning, paprika, salt, and pepper. Bring to a boil, then reduce heat and simmer for 15–20 minutes until potatoes are tender.
Finish the Chowder:
Stir in cream and let simmer for another 5 minutes. Adjust seasoning to taste.
Serve:
Ladle into bowls and garnish with parsley or green onions. Serve hot with crusty bread or cornbread.
