Southwest Cajun soup is a hearty, one-pot mash-up of Cajun-seasoned chicken and andouille with Southwest-style beans, corn, tomatoes, and green chiles. It is not a traditional regional dish, but the smoky sausage, warm spices, and bright lime make a satisfying, flexible soup that is easy to adjust for heat.
Ingredients
- 1 tablespoon (15 ml) neutral oil, such as canola
- 8 ounces (225 g) smoked andouille sausage, sliced into ¼-inch (6 mm) rounds
- 1 pound (450 g) boneless, skinless chicken breast, cut into ¾-inch (2 cm) pieces
- 1 medium yellow onion, about 1 cup (150 g) chopped
- 1 medium red bell pepper, about 1 cup (150 g) chopped
- 2 celery ribs, about ¾ cup (100 g) chopped
- 3 garlic cloves, about 1 tablespoon (12 g) minced
- 1 tablespoon (8 g) Cajun seasoning, plus more to taste
- 1 teaspoon (2 g) ground cumin
- 1 teaspoon (2 g) smoked paprika
- 1 can (14.5 ounces/410 g) diced tomatoes, with their juices
- 4 cups (960 ml) low-sodium chicken broth
- 1 can (15 ounces/425 g) black beans, drained and rinsed, about 1½ cups (255 g) drained
- 1½ cups (225 g) corn kernels, frozen or fresh
- 1 can (4 ounces/113 g) diced green chiles
- 1 bay leaf
- ½ teaspoon (3 g) kosher salt, plus more only if needed
- ¼ teaspoon (0.5 g) freshly ground black pepper
- 2 tablespoons (30 ml) fresh lime juice, from about 1 lime
- ¼ cup (10 g) chopped cilantro, for serving (optional)
- 2 scallions, about 2 tablespoons (12 g) sliced, for serving (optional)
- ½ cup (55 g) shredded Monterey Jack or cheddar, for serving (optional)
Instructions
- Prepare the vegetables, garlic, chicken, sausage, and beans before heating the pot. Keep the raw chicken and its cutting board separate from ready-to-eat ingredients, and wash your hands and tools after handling it. Drain and rinse the beans; this removes some of the canning liquid and lets you control the soup’s seasoning.
- Heat the oil in a large heavy pot or Dutch oven over medium-high heat. Add the sausage in an even layer and cook for about 4 minutes, stirring once or twice, until browned at the edges. Transfer it to a plate, leaving any rendered fat in the pot. If the sausage is very lean and the pot looks dry, add a teaspoon of oil.
- Add the chicken pieces in a single layer, working in batches if the pot is crowded. Cook for about 5 minutes, turning the pieces so they brown lightly on more than one side; they do not need to be cooked through yet. Move them to the plate with the sausage. Browning builds flavor, while finishing the chicken in the broth helps keep it tender.
- Reduce the heat to medium. Add the onion, bell pepper, and celery, then cook for 6 minutes, stirring occasionally and scraping up browned bits from the bottom. When the vegetables have softened, stir in the garlic, Cajun seasoning, cumin, and smoked paprika and cook for 1 minute. Keep the garlic moving so it becomes fragrant without scorching.
- Pour in the tomatoes and broth, then add the bay leaf, salt, and black pepper. Stir to loosen any browned bits. Return the sausage and chicken, including any juices on the plate, to the pot. Bring the liquid to a gentle boil, then lower the heat, cover, and simmer for 15 minutes. Keep the simmer steady rather than vigorous; a hard boil can make chicken less tender and cause liquid to evaporate too quickly.
- Stir in the beans, corn, and green chiles. Cover and simmer for 5 minutes, until the corn is hot and the chicken is fully cooked. Check several of the largest chicken pieces with an instant-read food thermometer: the USDA FSIS safe minimum internal temperature for poultry is 165°F (74°C). If any piece is below that temperature, continue simmering and check again. Remove the bay leaf.
- Turn off the heat and let the soup stand for 2 minutes, then stir in the lime juice. Taste before adding more salt because Cajun seasoning and sausage can both be salty. Add a little extra Cajun seasoning or black pepper if you want more warmth, ladle into bowls, and finish with cilantro, scallions, or cheese if desired.
Tips
- Choose the sausage with the flavor in mind. Andouille gives the soup its smoky, peppery Cajun character, but it can be hard to find in some grocery stores. Smoked kielbasa or another smoked pork sausage is a practical substitute; it will taste milder and may be less spicy. For poultry sausage, choose a smoked variety and brown it briefly, since it may release less fat.
- Check the seasoning label. Cajun blends vary: some are salty and hot, while others are mostly herbs and paprika. Starting with one tablespoon and waiting until the end to adjust helps prevent an overly salty pot. If your blend is salt-free, you may need more salt than the amount listed.
- Keep the chicken pieces similar in size. Pieces close to ¾ inch cook at a similar pace and are easy to check with a thermometer. Crowding the pot while browning can make the meat steam instead of brown, so work in batches if needed; the soup will still cook properly if the chicken gets only a light sear.
- Make it thicker or brothier to suit your bowl. For a thicker, stew-like texture, simmer uncovered for a few extra minutes before serving. For a looser soup, stir in up to ½ cup (120 ml) additional broth. Avoid adding a large amount of extra seasoning until you have tasted the finished broth.
Serving Suggestions
Serve the soup hot in deep bowls, with lime wedges so each person can brighten their portion to taste. Warm cornbread, skillet bread, or soft flour tortillas are useful for soaking up the broth. For a fuller meal, add a simple green salad dressed with lime and a little oil; crisp lettuce or cabbage also balances the soup’s smoky, savory flavors.
Set out toppings separately rather than stirring them into the pot. Cilantro and scallions add freshness, while shredded Monterey Jack or cheddar melts into the hot broth. Crushed tortilla chips or tortilla strips bring crunch, and sliced avocado adds a creamy contrast. If you use chips or salted cheese, taste the soup before adding extra salt at the table.
Variations
To make the soup without meat, omit both the sausage and chicken, use vegetable broth, and add another can of drained beans. Brown diced mushrooms in the oil before cooking the vegetables to add savory depth. The result will not have the same smoky sausage flavor, so consider adding a little extra smoked paprika; taste as you go rather than automatically increasing the salt.
For more heat, add ¼ teaspoon (0.5 g) cayenne with the other spices, or serve hot sauce on the side. For a gentler bowl, use mild Cajun seasoning and mild green chiles. If green chiles are unavailable, substitute ½ cup (75 g) chopped roasted poblano pepper for a mild, earthy flavor, or use a small amount of jalapeño for more direct heat.
You can change the beans or vegetables while keeping the basic method. Kidney or pinto beans work in place of black beans, and drained canned hominy can replace some or all of the corn for a chewier texture. If using fresh corn, cut the kernels from the cob and follow the same timing. Add quick-cooking greens such as chopped spinach during the final minute or two so they wilt without becoming dull.
For a different protein, use boneless, skinless chicken thighs cut into similar-sized pieces; they may need a little more simmering, so rely on the thermometer rather than the clock alone. If using cooked leftover chicken, do not brown it with the raw chicken. Simmer the soup without it, add the cooked chicken with the beans and corn, and heat it through to 165°F (74°C) before serving.
Storage and Reheating
Refrigerate leftovers within 2 hours of cooking. Divide a large pot among shallow, covered containers so it cools more quickly, then store the soup in the refrigerator for 3 to 4 days. Keep toppings such as chips, cheese, and herbs separate and add them when serving. The beans may soften a little as the soup sits, but the flavor will remain good.
For longer storage, freeze cooled soup in airtight, freezer-safe containers, leaving a little room for expansion. Use it within about 3 months for best quality. Thaw it overnight in the refrigerator when possible; if reheating from frozen, warm it gently in a covered saucepan with a splash of broth, stirring as it loosens. The texture of the corn and beans may soften after freezing.
Reheat only the amount you plan to eat, either in a saucepan over medium heat or in the microwave in a covered, microwave-safe bowl, stirring partway through. Heat leftovers to 165°F (74°C), checked with a food thermometer, before serving. Add a spoonful of water or broth if the soup has thickened in storage, and add fresh lime juice after reheating to restore its brightness.
Frequently Asked Questions
Is Southwest Cajun soup very spicy?
It can be mildly warm or quite spicy depending on the Cajun seasoning, sausage, and green chiles you choose. For a more predictable, gentle result, use mild sausage and mild chiles, then add cayenne or hot sauce at the table. If the finished soup is hotter than expected, serve it with rice, bread, or a little cheese to soften each bite.
Can I make this soup ahead?
Yes. Cook it through, cool it promptly, and refrigerate it for up to 3 to 4 days. The flavors mingle as it rests, and the broth may thicken slightly. Reheat to 165°F (74°C), then taste and adjust with a little broth, salt, or lime juice. Keep fresh garnishes separate until serving so they stay bright.
Can I use canned corn instead of frozen corn?
Yes. Drain canned corn before measuring and use the same 1½ cups (225 g). Add it with the beans and green chiles as directed; it needs only enough time to heat through. Frozen corn can go straight into the pot without thawing, though the soup may take an extra minute to return to a simmer.
What can I use instead of andouille sausage?
Smoked kielbasa, smoked turkey sausage, or another smoked sausage will work. Kielbasa is usually less peppery, while turkey sausage may be leaner, so the soup may have a lighter smoky flavor and less rendered fat. If you cannot find any smoked sausage, omit it and add a little smoked paprika, then season carefully at the end.
Can I make this soup in a slow cooker?
The stovetop method gives the sausage and chicken a chance to brown, which adds flavor and makes it easier to control the final texture. For a slow cooker, brown the sausage, chicken, and vegetables first, then transfer them with the broth, tomatoes, seasonings, and bay leaf. Cook until the chicken reaches 165°F (74°C); add the beans, corn, and chiles near the end so they heat through without breaking down. Slow cookers vary, so check the appliance instructions and use a thermometer rather than relying only on a fixed time.
