Before you start

Before starting, ensure that all your ingredients are washed and prepped. Specifically, dice the chicken thighs into uniform pieces to ensure even cooking, and slice the smoked sausage into rounds. Wash and slice the red bell peppers into strips, removing the stems and seeds.

Have your measuring tools ready on the counter to streamline the assembly process, and confirm that your slow cooker insert is clean and positioned on a stable, heat-resistant surface near a power outlet.

Ingredients at a glance (5)
  • 2 lb boneless skinless chicken thighs, diced
  • 1 lb smoked sausage, sliced
  • 2 large red bell peppers, sliced
  • 2 tbsp cajun spice blend
  • 2 cups crushed tomatoes

Instructions

Layering the ingredients

  1. Prepare and combine ingredients
    Place the diced chicken and sliced smoked sausage into the base of your slow cooker. Add the sliced red bell peppers on top of the meat, then evenly sprinkle the cajun spice blend over the mixture to ensure balanced flavor distribution.
    Look for The slow cooker insert should be filled with the raw ingredients.
    Tip Ensure the chicken pieces are cut to a uniform size to promote even cooking throughout the process.

At the end of this phase, the slow cooker should be filled with raw chicken, sausage, peppers, and spices. The ingredients should be arranged in a way that allows the heat to circulate properly. Take a moment to ensure that the spices are distributed evenly over the top of the other ingredients so they can begin to infuse the mixture as the cooker heats up.

Slow cooking process

  1. Add liquids and cook
    Pour the crushed tomatoes over the ingredients. Cover the slow cooker with its lid and set to cook on low for 4 hours. Do not lift the lid during the cooking process, as this releases essential heat and moisture needed for the dish.
    Look for The mixture should be fully incorporated and the cooker sealed.
    Tip Using a glass measuring cup makes pouring the crushed tomatoes clean and easy.

During this phase, the primary goal is to allow the flavors to meld and the meat to reach a tender consistency. You will notice the aroma of the cajun spices filling the kitchen as the tomatoes break down into a rich sauce.

The slow cooker should remain covered throughout this entire period to maintain a consistent temperature and ensure the chicken cooks safely.

Final check and serving

  1. Finish and serve
    Once the cooking time is complete, verify the chicken has reached an internal temperature of 165°F (74°C). Gently stir the jambalaya to combine the juices and serve immediately on warm plates. Let the dish rest for 5 minutes before serving.
    Look for The chicken should be tender and the sauce should have thickened slightly.
    Safe temperature 165°F (74°C) internal temperature (poultry)
    Tip A quick stir just before serving ensures the spices are evenly distributed throughout the final dish.

At this final stage, the jambalaya should be steaming and fragrant. The chicken should be cooked through and easily pierced with a fork. Before serving, give the mixture a thorough stir to incorporate any juices that have settled at the bottom of the insert. The final dish should be glossy, aromatic, and ready to be plated for immediate enjoyment.

Common mistakes

A common mistake is overcrowding the slow cooker or failing to cut the chicken into uniform pieces, which can lead to uneven cooking where some pieces are tough while others are overcooked.

Avoid lifting the lid frequently to check on the dish, as this causes significant heat loss and extends the required cooking time. Additionally, ensure you do not use pre-cooked sausages that are overly salty, as the cajun spices already contribute a significant amount of sodium to the dish.

How to tell it’s done

The jambalaya is ready when the chicken is fully cooked through and tender. Use a digital meat thermometer to ensure the center of the largest chicken piece has reached at least 165°F (74°C).

The sauce should be thickened and fragrant, with the bell peppers softened but still holding their shape. If the sauce appears too thin, you can continue to cook on high for a short period with the lid off to allow for evaporation.

  • Ground meat: 160°F (71°C) in the thickest part
