This list might seem straightforward, but every ingredient here is essential in creating the perfect balance of flavor, texture, and color that makes this gumbo truly unforgettable. From the holy trinity of vegetables to the aromatic spices and the star proteins, each plays a vital role.
- 4 tablespoons butter: Perfect for starting your roux with a rich, silky base.
- 1/4 cup + 2 tablespoons flour: Essential to thicken the gumbo, creating that luscious consistency.
- 1 red bell pepper, diced: Adds sweet, vibrant color and a subtle fresh flavor.
- 1 onion, diced: Builds depth and sweetness that softens as it cooks.
- 3 celery stalks, diced: Brings a nice crunch and earthy undertone.
- 28 ounce can diced tomatoes: Injects a subtle acidity and some body to the broth.
- 1 ½ pounds chicken thighs, boneless skinless: Tender and juicy, a classic gumbo protein that soaks up spices beautifully.
- 1 package andouille sausage, sliced: Adds a smoky, slightly spicy kick that is signature to Cajun cooking.
- 1 pound raw shrimp: A sweet, briny finish to this dish added towards the end for perfect texture.
- 1 tablespoon cajun seasoning: Brings that authentic Cajun heat and flavor complexity.
- 1 teaspoon kosher salt: Enhances and balances all the flavors.
- ½ teaspoon dried thyme: A subtle herbaceous layer that complements the spices.
- 2 cups chicken broth: Creates a savory, comforting liquid base for the gumbo.
- 1 teaspoon minced garlic: Infuses wonderful aromatic warmth.
- 2 cups cooked rice: Serves as the perfect bed to soak up the delicious gumbo juices.
How to Make Slow Cooker Cajun Chicken and Shrimp Gumbo Recipe
Step 1: Make the Roux (Optional but Recommended)
Starting with the roux sets the tone for a deep, rich gumbo. Melt the butter in a skillet over medium heat, then whisk in the flour. Keep whisking continuously as the mixture darkens to a deep brown, about 4 minutes. The roux might seem simple, but it’s the magic that thickens the gumbo and adds intense flavor. Set it aside until you’re ready to add it to the slow cooker.
Step 2: Gather the Essentials in the Slow Cooker
Layer the diced red bell pepper, onion, celery, canned diced tomatoes, chicken thighs, sliced andouille sausage, cajun seasoning, salt, dried thyme, chicken broth, and minced garlic straight into the slow cooker. If you made the roux, add it now to meld all the flavors together. Be careful not to add the shrimp just yet—they need less cooking time and will be added near the end.
Step 3: Slow Cook to Perfection
Give everything a good stir to combine all those incredible ingredients, then cover and cook on LOW for 6 to 7 hours, or on HIGH for 3 to 4 hours. As the hours pass, the flavors deepen, and the chicken becomes incredibly tender—ready to soak up that full Cajun essence.
Step 4: Add the Shrimp for a Tender Finish
About 15 minutes before serving, stir in the raw shrimp. Leaving the shells on helps add extra flavor, but peeled shrimp works fine too. Once the shrimp turn pink and opaque, the gumbo is ready to enjoy. Don’t forget to shred the chicken thighs into bite-sized pieces before serving.

Garnishes
Garnishing your gumbo adds that extra layer of freshness and color. Think chopped green onions, fresh parsley, or a sprinkle of sliced okra if you want to be traditional. A dash of hot sauce can also bring a lively kick to your bowl.
Side Dishes
While the gumbo itself is a hearty meal, serving it with classic steamed white rice really lets the flavors shine. Crusty French bread or warm cornbread are fantastic for soaking up every last drop of that rich sauce.
Creative Ways to Present
Try serving your Slow Cooker Cajun Chicken and Shrimp Gumbo Recipe in small bowls as an appetizer for a party, or ladle it over creamy grits for a southern twist. You could even turn leftovers into a spicy gumbo pasta by mixing it with cooked linguine for the next day’s meal.
Make Ahead and Storage
Storing Leftovers
Leftover gumbo tastes even better the next day once the flavors have had extra time to mingle. Store it in an airtight container in the refrigerator for up to 3 days.
Freezing
This gumbo freezes beautifully. Portion it into freezer bags or containers and freeze for up to 3 months. Thaw overnight in the fridge before reheating for optimal texture and flavor.
Reheating
Reheat your gumbo gently on the stove over medium-low heat, stirring occasionally until warmed through. Add a splash of broth or water if it seems too thick. Avoid microwaving if possible, to preserve the texture of the shrimp and sausage.
FAQs
Can I use frozen shrimp instead of fresh?
Yes, frozen shrimp work just fine! Just be sure to thaw them completely before adding during the last 15 minutes of cooking, so they don’t overcook.
Is the roux necessary?
The roux is optional but highly recommended because it transforms the gumbo’s texture and flavor. If you’re short on time, you can skip it, but taking the extra step is worth it.
Can I substitute the chicken with another protein?
Feel free to swap chicken thighs for chicken breasts or even turkey sausage, but chicken thighs provide the best tenderness and flavor balance in this gumbo.
How spicy is this gumbo?
The spice level depends on your Cajun seasoning and whether you add hot sauce. It usually has a warm, mellow heat, but you can adjust to taste with more or less seasoning.
What’s the best rice to serve with gumbo?
Long-grain white rice is traditional and perfect for soaking up the rich sauce, but brown rice or even cauliflower rice works for a healthier twist.

- 1 tablespoon Cajun seasoning
- 1 teaspoon kosher salt
- ½ teaspoon dried thyme
- 2 cups chicken broth
- 1 teaspoon minced garlic
- 2 cups cooked rice (for serving)
Instructions
- Prepare the Roux (Optional): In a skillet over medium heat, melt the butter until it begins to bubble.

Remove from heat and set aside to cool until ready to add to the slow cooker.
- Add Ingredients to Slow Cooker: Add the diced red bell pepper, onion, celery, diced tomatoes with their juice, chicken thighs, sliced andouille sausage, Cajun seasoning, kosher salt, dried thyme, chicken broth, minced garlic, and the prepared roux if using into the slow cooker. Do not add the shrimp at this stage.
- Cook the Gumbo: Stir all ingredients to combine evenly. Cover and cook on LOW for 6-7 hours or on HIGH for 3-4 hours, allowing the flavors to meld and the chicken to become tender.
- Add Shrimp: About 15 minutes before the end of cooking, stir in the raw shrimp (shells can be left on for extra flavor). Continue cooking until the shrimp turn pink and opaque, indicating they are fully cooked.
- Finish and Serve: Remove the chicken thighs from the crockpot and shred them into bite-sized pieces, then return the chicken to the gumbo and stir. Serve the gumbo hot over a bed of cooked rice for a complete meal.
Notes
- The roux is optional but adds a richer, deeper flavor and slightly thickens the gumbo.
- Leaving shrimp shells on during cooking enhances the broth’s flavor, but you can peel them if preferred.
- Adjust Cajun seasoning level to taste for desired spiciness.
- Use low-sodium chicken broth to control salt content if needed.
- Leftover gumbo tastes even better the next day once flavors have melded further.
- You can substitute chicken breasts for thighs but thighs provide more moisture and flavor.
