Start by slicing your smoked sausage into rounds and chopping all vegetables—bell peppers, onion, and celery—into small, even pieces.
Heat a skillet over medium heat and add the sausage slices, cooking for about 3-4 minutes until they turn slightly crispy and release a smoky aroma. This step develops depth of flavor.
Meanwhile, place the chicken thighs into the slow cooker, spreading them out evenly.
Add the browned sausage, chopped bell peppers, onion, and celery over the chicken in the slow cooker.
Sprinkle the paprika, cayenne, thyme, and season with salt and pepper over the ingredients in the slow cooker. Pour in the chicken broth.
Cover the slow cooker and cook on low for 6 to 8 hours, until the chicken is tender and flavors meld together.
About halfway through, give the stew a gentle stir to combine flavors evenly and check if you need to add a splash more broth.
In the last hour of cooking, add the sliced okra to the gumbo, stirring it in gently. This preserves some of its texture and prevents over-sliminess.
Once cooking is complete, open the lid and check the aroma—rich, smoky, and fully seasoned. Taste and adjust salt or spice as needed.
Serve the gumbo hot in bowls, garnished with chopped green onions or parsley if desired, and enjoy the hearty, layered flavors.
