Ingredients for Easy Keto Cajun Chicken and Shrimp Soup Recipe
Soup Base
- 2 tablespoons butter
- 1 tablespoon olive oil
- 1 medium onion, diced
- 2 ribs celery, diced
- 4 cloves garlic, minced
Protein
- 1 pound boneless, skinless chicken breast, cut into bite-size pieces
- 12 ounces raw shrimp, peeled and deveined
Liquids & Creaminess
- 4 cups chicken broth
- 1 cup heavy cream
- 4 ounces cream cheese, softened
Seasonings
- 1ยฝ tablespoons Cajun seasoning
- ยฝ teaspoon smoked paprika
- ยผ teaspoon cayenne pepper (optional, adjust to taste)
- ยฝ teaspoon salt, or to taste
- ยผ teaspoon black pepper
Garnish (Optional)
- Chopped fresh parsley or green onions
Ingredient Notes
For a milder soup, reduce the Cajun seasoning or skip the cayenne. If you prefer a lighter dairy option, you can use half-and-half, though it will slightly increase carbs. For dairy-free keto, use full-fat coconut cream and dairy-free cream cheese; the flavor will be slightly sweeter but still delicious. Chicken thighs can be substituted for chicken breast for a richer taste.
Step-by-Step Instructions
Step 1 โ Sautรฉ the Vegetables
In a large pot or Dutch oven, heat the butter and olive oil over medium heat. Add the diced onion and celery and cook for 4 to 5 minutes, stirring occasionally, until softened. Add the minced garlic and cook for 30 seconds until fragrant.
Step 2 โ Cook the Chicken
Add the chicken pieces to the pot and sprinkle with Cajun seasoning, smoked paprika, salt, and black pepper. Stir well and cook for about 5 to 6 minutes, until the chicken is mostly cooked and lightly browned on the outside.
Step 3 โ Simmer the Soup
Pour in the chicken broth and bring the mixture to a gentle simmer. Reduce the heat to medium-low and let it cook for 10 minutes so the flavors can develop and the chicken finishes cooking.
Step 4 โ Make It Creamy
Lower the heat and stir in the softened cream cheese until fully melted and smooth. Slowly pour in the heavy cream while stirring continuously to create a rich, creamy broth.
Step 5 โ Add the Shrimp
Add the shrimp to the pot and cook for 3 to 4 minutes, or until they turn pink and opaque. Be careful not to overcook them, as shrimp cook very quickly.
Step 6 โ Taste and Serve
Taste the soup and adjust seasoning if needed. Garnish with chopped parsley or green onions and serve hot.
Pro Tips for Success
Use good-quality Cajun seasoning for the best flavor and check labels to ensure itโs low in carbs. Cut the chicken into evenly sized pieces so it cooks at the same rate. Keep the soup at a gentle simmer after adding cream to prevent curdling. Add shrimp at the very end to keep them tender and juicy. If the soup thickens too much, add a splash of chicken broth to loosen it.
Flavor Variations
Add sliced andouille-style chicken sausage for extra Cajun flair. Stir in a handful of chopped spinach at the end for added nutrients. Use shrimp only and skip the chicken for a seafood-focused version. Add a squeeze of lemon juice before serving to brighten the flavors. Increase smoked paprika for a deeper smoky taste without extra heat.
Serving Suggestions
Serve this soup on its own for a complete keto meal or pair it with a simple side salad with a low-carb dressing. It also goes well with keto biscuits or almond flour bread for dipping. For extra richness, top with a small sprinkle of shredded cheddar or Parmesan cheese.
Storage and Freezing Instructions
Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stovetop over low heat, stirring often. This soup can be frozen, but the texture may change slightly due to the cream. If freezing, cool completely and freeze for up to 2 months, then thaw overnight in the refrigerator before reheating slowly.
