Cajun Soup Recipes: Chicken, Sausage, and Rice Soup

This Cajun chicken, sausage, and rice soup is a hearty Louisiana-inspired pot of browned andouille, tender chicken, vegetables, and rice in a savory roux-thickened broth. Cajun cooking has regional and family variations, so this version keeps the flavors flexible: build a deep base, then adjust the heat and seasoning to suit your table.

Ingredients

12 oz (340 g) fully cooked smoked andouille sausage, sliced into ¼-inch (6 mm) rounds
1 lb (450 g) boneless, skinless chicken thighs, cut into bite-size pieces
⅓ cup (80 ml) neutral oil, such as canola or vegetable oil, divided
⅓ cup (42 g) all-purpose flour
1 medium yellow onion, diced, about 1 cup (150 g)
2 celery ribs, diced, about 1 cup (100 g)
1 medium green bell pepper, diced, about 1 cup (150 g)
3 garlic cloves, finely chopped, about 1 tablespoon (9 g)
1 tablespoon (6 g) Cajun seasoning, preferably a lower-sodium blend
½ teaspoon (1 g) dried thyme
2 bay leaves
8 cups (1.9 L) low-sodium chicken broth
1 cup (185 g) long-grain white rice, rinsed and drained
½ teaspoon (3 g) kosher salt, plus more to taste
¼ teaspoon (0.5 g) freshly ground black pepper, plus more to taste
2 green onions, thinly sliced, for serving
1 tablespoon (15 ml) chopped fresh parsley, for serving (optional)
Hot sauce, for serving (optional)

Instructions

Prepare the ingredients. Dice the onion, celery, and bell pepper; chop the garlic; slice the sausage; and cut the chicken into evenly sized pieces. Rinse the rice under cool water until the water runs mostly clear, then drain it. Measure the flour, oil, broth, and seasonings before you start the roux, since the next steps move quickly.
Brown the sausage. Heat 1 tablespoon (15 ml) of the oil in a large, heavy-bottomed soup pot or Dutch oven over medium heat. Add the sausage and cook for about 6 minutes, turning the slices so they brown on both sides. Transfer the sausage to a plate. Leave a thin coating of fat in the pot; if the sausage releases a lot, pour off the excess.
Brown the chicken. Add another 1 tablespoon (15 ml) oil to the pot if it looks dry. Add the chicken in a single layer, working in batches if needed, and brown for about 6 minutes, turning the pieces once or twice. They do not need to be cooked through yet. Transfer them to the plate with the sausage. Avoid crowding the pot, which can make the chicken steam instead of brown.
Make the roux. Reduce the heat to medium-low. Add the remaining oil, then whisk in the flour. Cook, stirring constantly with a whisk or flat-edged wooden spoon, for about 10 minutes, until the roux is the color of peanut butter or a little darker and smells toasted. Keep it moving across the bottom of the pot. If you see black flecks or smell burning, discard it and start again; a scorched roux will make the whole soup bitter.
Cook the vegetables. Add the onion, celery, and bell pepper to the roux and stir carefully to coat them. Cook for about 5 minutes, until they begin to soften. Add the garlic, Cajun seasoning, thyme, salt, and pepper, then stir for 3 minutes. The mixture will be thick; that is expected. If it catches on the bottom, lower the heat and stir in a small splash of broth.
Simmer the soup. Slowly pour in the broth while stirring, scraping the bottom and sides of the pot to loosen any browned bits and smooth out the roux. Add the bay leaves, browned sausage, and chicken with any juices on the plate. Bring the soup to a gentle boil, then lower the heat to maintain a steady simmer. Cover partially and cook for 20 minutes, stirring occasionally. Check a large chicken piece with a food thermometer; USDA FSIS recommends that poultry reach a safe minimum internal temperature of 165°F (74°C). If it has not reached that temperature, continue simmering and check again.
Add the rice and finish. Stir in the drained rice. Keep the soup at a gentle simmer, uncovered, for 15 minutes, stirring more often near the end so rice does not settle and stick. Check that the rice is tender; if it is still firm, simmer for a few more minutes and add a little hot broth or water if the soup has become too thick. Remove the bay leaves, taste, and adjust the salt, pepper, or Cajun seasoning. Serve hot with green onion, parsley, and hot sauce if desired.

Tips

Choose the right pot and heat. A heavy pot distributes heat more evenly while you cook the roux. Keep the roux at medium-low and stir continuously; turning up the heat to save time makes it easier to burn before the flour develops its toasted flavor.
Use a sausage substitute thoughtfully. Andouille gives the soup a smoky, assertive flavor and can be hard to find outside some grocery stores. Smoked kielbasa or another fully cooked smoked sausage works, but it is usually milder, so taste the broth before adding extra Cajun seasoning or hot sauce.
Watch the salt and spice. Sausage and Cajun seasoning blends vary in salt and heat. Starting with low-sodium broth gives you more control. If your seasoning is already salty, reduce or omit the measured salt and finish the soup to taste.
Do not let the rice quietly overcook. Rice continues to absorb broth as it sits, so simmer only until tender and serve soon after. For leftovers with a looser, more soup-like texture, cook the rice separately and spoon it into each bowl instead of simmering it in the pot.

Serving Suggestions

Serve this soup in warm bowls with sliced green onions, parsley, and hot sauce on the side so everyone can choose their own level of heat. Cornbread, crusty bread, or simple crackers are useful for catching the roux-rich broth. A crisp green salad or lightly dressed cabbage slaw makes a fresh contrast to the smoky sausage and filling rice.

If you expect leftovers, consider serving the rice separately. Ladle the broth, chicken, sausage, and vegetables into bowls first, then add a scoop of rice. That keeps the rice from soaking up most of the liquid while the soup waits on the table, and it makes it easier to reheat the soup without the grains becoming overly soft.

Variations

Make it seafood-style: Replace the chicken with peeled, deveined shrimp, but do not add the shrimp during the long simmer. Make the soup through the broth step, simmer the rice until nearly tender, then add the shrimp for the last few minutes. Cook until opaque and until a thermometer inserted into the thickest piece reads 145°F (63°C), the USDA FSIS safe minimum for fish and shellfish. Shrimp cooks quickly, so keep an eye on it.

Use chicken breast: Boneless, skinless breast can replace the thighs in the same quantity. Cut it into evenly sized pieces and check for 165°F (74°C); breast meat can become dry if it simmers longer than necessary. Thighs are more forgiving and tend to stay tender in a long-simmered soup.

Make it gluten-free: Use a gluten-free all-purpose flour blend that is suitable for roux and verify that the Cajun seasoning and sausage are labeled gluten-free. Some blends thicken differently, so add the broth gradually and expect a slightly different texture. For a naturally roux-free variation, omit the flour and oil roux, then simmer the soup and use a small amount of cornstarch mixed with cold water near the end; this creates a smoother, less toasted-tasting broth.

Adjust the heat or add vegetables: For a gentler pot, use mild smoked sausage and omit hot sauce; for more heat, add a pinch of cayenne or pass hot sauce at the table. Diced okra can be added with the vegetables, or a cup of frozen corn can be stirred in near the end. These are flexible additions rather than required ingredients, and they change the soup’s texture and sweetness slightly.

Storage and Reheating

Refrigerate the soup within 2 hours of cooking, dividing a large batch among shallow containers so it cools more quickly. Keep it covered and refrigerated for 3 to 4 days. If the rice has been cooked in the soup, expect it to absorb broth and soften as it sits; loosen portions with a splash of water or broth when reheating. For the best texture, store cooked rice separately from the soup when practical.

Reheat only the portion you plan to eat in a saucepan over medium heat, stirring occasionally, until it is steaming throughout and reaches 165°F (74°C); USDA FSIS advises reheating leftovers to that temperature. Add broth or water if needed, and avoid a prolonged hard boil, which can break down the rice and chicken. In a microwave, cover the bowl loosely, stir partway through, and check the center with a food thermometer. Freeze cooled soup for about 2 to 3 months for best quality, preferably without rice; thaw in the refrigerator and reheat to 165°F (74°C). Do not leave cooked soup at room temperature for more than 2 hours.

Frequently Asked Questions

Is this Cajun soup very spicy?
The recipe is moderately seasoned, but the heat depends on the sausage and Cajun seasoning you use. Some blends include cayenne while others are mild. Start with the listed amount, taste after simmering, and offer hot sauce separately so the whole pot does not become too spicy for some diners.

Can I make the soup ahead?
Yes. For the best texture, prepare the soup through the broth-and-chicken simmer, cool it promptly, and refrigerate it for up to 3 to 4 days. Cook fresh rice when you are ready to serve, or store rice separately. Reheat the soup to 165°F (74°C) before serving, then add the rice to bowls.

Why did my roux turn lumpy?
A roux can clump if broth is poured in all at once or if it is not stirred as it is added. Pour in the broth gradually while whisking, especially for the first few additions. If small lumps remain, keep whisking as the soup heats; an immersion blender can smooth the broth, though it will also blend some of the vegetables.

Can I use brown rice?
Brown rice usually takes longer to cook than white rice, and its timing varies by variety. Rather than extending the soup’s simmer and risking overcooked chicken, cook brown rice separately according to its package directions and serve it in the bowls. The soup will remain easier to store and reheat this way, too.

Can I make it without andouille?
Yes. Use another fully cooked smoked sausage, such as smoked kielbasa, or leave sausage out and increase the chicken. Without andouille, the broth will lose some of its smoky, peppery character, so taste before serving and adjust the Cajun seasoning. If you omit sausage, add a little oil when browning the chicken.
