Before you start
Before starting, chop the onion, bell pepper, celery, and garlic, and slice the smoked sausage. Measure out the rice, broth, and Cajun seasoning. Have the shrimp thawed and peeled, and the green onions chopped. If using an older slow cooker that runs hot, check the rice at the 3-hour mark to prevent overcooking.

Instructions
Phase 1: Build the Base
- Prep the BaseAdd the rice, chicken broth, diced tomatoes, onion, bell pepper, celery, garlic, Cajun seasoning, and sliced smoked sausage to the slow cooker. Stir well to combine everything.Look for The mixture should be well combined with the sausage evenly distributed.Tip Use a wooden spoon to avoid scratching the slow cooker insert.
- Cook the RiceCover the slow cooker and cook on low for 3 to 4 hours, or until the rice is tender and has absorbed most of the liquid. Stir once halfway through if possible.Look for The rice should be tender and the mixture should look thick and creamy, not soupy.Tip Resist lifting the lid too often; each peek adds 20 minutes of cooking time.
At the end of this phase, the slow cooker is full of a colorful mixture of rice, vegetables, sausage, and seasoned broth. The liquid should be bubbling gently around the edges, and the aroma of Cajun spices and smoked sausage should fill the kitchen.
The vegetables have softened slightly, and the rice is starting to absorb the flavorful liquid. Before moving on, ensure the rice is not sticking to the sides of the cooker.
Phase 2: Cook the Shrimp
- Add the ShrimpAdd the shrimp to the slow cooker and gently fold them into the rice mixture. Cover and cook on low for another 20 to 30 minutes, until the shrimp are pink and opaque.Look for The shrimp should be curled and pink, with no translucent spots.Safe temperature 145°F (63°C) internal temperature (shellfish)Tip Stir gently to avoid breaking the shrimp.
- Check the TemperatureInsert an instant-read thermometer into the thickest part of a shrimp to ensure it has reached 145°F (63°C). This is the safe minimum internal temperature for shellfish.Look for The thermometer should read at least 145°F (63°C).Safe temperature 145°F (63°C) internal temperature (shellfish)Tip If not there yet, cook 5 more minutes and check again.
After adding the shrimp, they should turn from gray to pink and curl slightly within about 20 minutes. The jambalaya should look thick and creamy, with the rice fully cooked and the shrimp nestled throughout.
The shrimp should feel firm to the touch and have no translucent spots. The smell is intensely savory with a hint of the sea. Check the temperature of a shrimp to confirm it has reached 145°F (63°C).
Phase 3: Finish and Serve
- Season and FinishTaste the jambalaya and season with salt and black pepper as needed. Stir in the chopped green onions, reserving a few for garnish if desired.Look for The green onions should be bright and fresh.Tip The Cajun seasoning is often salty, so taste before adding salt.
- ServeSpoon the jambalaya into a shallow bowl, making sure to get a good mix of rice, shrimp, and sausage in each serving. Serve hot.Look for The jambalaya should be steaming and aromatic.Tip A side of hot sauce works well for extra heat.
The jambalaya is now a hearty, steaming mound of seasoned rice, pink shrimp, and slices of smoked sausage, topped with bright green onions. The texture is moist and slightly creamy, not dry or soupy.
The flavors are bold and well-balanced, with the smoky sausage and spicy Cajun seasoning coming through clearly. The dish is ready to be scooped into bowls and served immediately.
Common mistakes
One common mistake is lifting the lid too often, which lets out heat and extends the cooking time. Another is adding the shrimp too early, causing them to become tough and rubbery.
Also, be careful not to overseason with salt before tasting, as Cajun seasoning often contains a good amount of salt. Finally, avoid using quick-cooking or instant rice, which will turn to mush during the long cooking time.
How to tell it’s done
The jambalaya is done when the rice is tender and has absorbed most of the liquid, and the shrimp are pink and opaque. To be sure, insert an instant-read thermometer into the thickest part of a shrimp; it should read at least 145°F (63°C). The mixture should be thick and creamy, not soupy. If the rice is still crunchy, cook for another 20 minutes and check again.
