Cooking Steps

• Heat a large pot over medium-high heat. Add sausage and let it sear for 1 minute, then use a wooden spoon to crumble it. Cook until sausage is deeply browned. Transfer to a plate lined with paper towels, leaving about 1 tablespoon grease in the pot. If there's not enough grease, add 1 tablespoon olive oil.
• In the same pot, melt 1 tablespoon butter. Add diced carrots, celery, and onion. Sauté for 5–7 minutes (or 7–10 minutes if the veggies are larger). Add garlic and cook for 30 seconds more.
• Stir in chopped potatoes, dried basil, dried parsley, salt, and pepper. Pour in chicken stock, bring the mixture to a boil, then reduce heat to medium-low. Cover pot and cook for 15–20 minutes or until potatoes are fork-tender.
• While potatoes cook, melt 4 tablespoons butter in a separate medium pot over medium heat. Stir in flour and cook, whisking constantly, for 1 minute. Slowly pour in milk, whisking constantly until smooth. Cook, continuing to whisk, until the mixture thickens and gently boils. Stir in heavy cream, then remove from heat.
• Once veggies are tender, stir in the milk/cream mixture. Turn off heat and add shredded cheese, a handful at a time, stirring gently until melted. Stir in sour cream, then return the sausage to the soup. Adjust seasoning with salt and pepper to taste.
• Serve the soup warm with hearty buttered bread, if desired.
