Equipment

Method
 

Sauté the base
  1. Melt the butter in a large Dutch oven over medium heat. Keep it moving until fully melted and glossy, about 1 minute.
  2. Add the sliced smoked sausage and cook until lightly browned. Stir occasionally until the edges color, about 4–6 minutes.
  3. Stir in the diced onion, celery, and red bell pepper. Cook for 5 minutes until the vegetables soften.
Build flavor and simmer
  1. Add the minced garlic and cook for 30 seconds. Stir constantly so it doesn’t brown.
  2. Stir in the cubed russet potatoes, Cajun seasoning, smoked paprika, and black pepper. Mix until the potatoes are coated with spices.
  3. Pour in the chicken broth and bring to a boil. Look for steady bubbling across the surface.
  4. Reduce heat and simmer for 20 minutes until potatoes are tender. A fork should slide in easily through the largest cubes.
Thicken and finish
  1. Mash some of the potatoes with a potato masher for a thicker texture. Stop when you get a mix of creamy and chunky pieces.
  2. Stir in the heavy cream and shredded cheddar cheese. Mix until the cheese melts and the soup looks smooth and creamy.
  3. Simmer for 3–4 minutes until creamy. You should see gentle bubbling and a slightly thickened consistency.
Serve
  1. Serve topped with the cooked crumbled bacon and sliced green onions. Add toppings right before serving for best texture.

Notes

For a thicker soup, mash more of the potatoes after simmering; if it gets too thick, loosen with a splash of chicken broth. Refrigerate leftovers in an airtight container for up to 3 days; freeze yes (up to 2 months), though creaminess may be slightly reduced when reheated. For a lighter option, use half-and-half instead of heavy cream and add the cheese gradually to help it melt smoothly.
