# What You’ll Use:

01 - 4 cups Yukon Gold or red potatoes, diced
02 - 1 cup onions, chopped
03 - 1 cup bell peppers, chopped
04 - 1 cup celery, chopped
05 - 3 cloves garlic, minced

→ Protein

06 - 12 oz andouille sausage, sliced into bite-sized pieces

→ Liquids and Dairy

07 - 4 cups chicken broth (gluten free if needed)
08 - 1 cup heavy cream or half and half

→ Fats and Oils

09 - 2 tablespoons butter
10 - 1 tablespoon olive oil

→ Seasonings and Garnish

11 - 2 tablespoons Cajun seasoning
12 - Salt and black pepper, to taste
13 - Sliced green onions or chives, for garnish
14 - Optional: shredded cheese, crispy bacon bits, sour cream, chopped fresh parsley

# How-To:

01 - Dice potatoes into 1/2-inch cubes. Chop onions, bell peppers, and celery into uniform pieces. Mince garlic cloves. Slice andouille sausage into 1/4-inch rounds.
02 - Heat butter and olive oil in a large soup pot over medium heat. Add andouille sausage slices and cook for 3–4 minutes until browned and fragrant. Remove sausage with a slotted spoon and set aside, leaving rendered fat in pot.
03 - Add onions, bell peppers, and celery to the pot. Sauté for 5–7 minutes until vegetables are softened and onions are translucent. Add minced garlic and cook for 30 seconds until fragrant, being careful not to burn.
04 - Return browned sausage to the pot. Sprinkle Cajun seasoning evenly over ingredients and stir to coat thoroughly, allowing spices to bloom for 1 minute.
05 - Add diced potatoes and chicken broth to the pot. Increase heat to bring mixture to a boil, then reduce to medium-low and simmer uncovered for 15–20 minutes until potatoes are fork-tender.
06 - Use an immersion blender to partially puree the soup directly in the pot, blending for 10–15 seconds to break down some potatoes while leaving chunks for texture. Alternatively, transfer 2 cups of soup to a blender, puree until smooth, and return to pot.
07 - Pour in heavy cream or half and half, stirring gently to incorporate. Reduce heat to low and warm through for 2–3 minutes without bringing to a boil to prevent curdling. Taste and adjust seasoning with salt, pepper, or additional Cajun seasoning as needed.
08 - Ladle hot soup into serving bowls. Garnish generously with sliced green onions or chives. Add optional toppings such as shredded cheese, crispy bacon bits, sour cream, or fresh parsley as desired. Serve immediately.

# Expert Advice:

01 -
  • The andouille sausage does all the heavy lifting for flavor, making you look like you spent hours on something that came together in under an hour
  • That perfect balance of creamy comfort and just enough kick to warm you up from the inside out
  • It makes the house smell incredible and tastes even better as leftovers the next day
02 -
  • The longer you let the sausage brown in that butter, the deeper your soup will taste
  • Don't skip the partial blending step, it's what makes this soup feel restaurant quality instead of just chunky potato soup
  • Once the cream goes in, keep the heat gentle or you'll end up with separated cream, which still tastes fine but isn't as pretty
03 -
  • If you can find andouille from a local butcher instead of the grocery store, it's worth every penny for the difference in flavor
  • The soup thickens as it sits, so thin it with a splash more broth or cream when reheating leftovers
