Before you start

Before you begin, ensure your chicken is cut into uniform, bite-size pieces to promote even cooking throughout the slow cooker. Wash and dice your bell peppers, removing all seeds and white membranes for the best flavor.

Have your Italian seasoning and marinara sauce measured and ready to go. Clear a space on your countertop for the slow cooker, ensuring it is placed on a heat-resistant surface away from any water sources or flammable materials like curtains or dish towels.

Ingredients at a glance (4)
  • 1 1/2 lb boneless, skinless chicken thighs, cut into bite-size pieces
  • 2 cups diced red and green bell peppers
  • 1 tbsp Italian seasoning
  • 24 oz marinara sauce

Instructions

Layering the ingredients

  1. Prepare the slow cooker base
    Place the bite-size pieces of raw chicken thighs into the bottom of the slow cooker bowl. Ensure they are evenly distributed to allow for uniform cooking during the long simmering process.
    Look for The chicken pieces should cover the bottom of the crockpot in a relatively even layer.
    Tip If the chicken pieces are too large, they may take longer to cook through evenly.

At the end of this phase, your slow cooker should be loaded with the chicken at the bottom, topped with the peppers, seasonings, and sauce. Everything should be arranged in a stable, organized fashion. Check that the chicken pieces are not clumped together in one large mass, as this would prevent the heat from circulating effectively around every piece of meat during the initial stages of the cooking process.

Slow simmering

  1. Layer the vegetables and seasonings
    Scatter the diced red and green bell peppers over the chicken layer. Sprinkle the Italian seasoning evenly across the peppers, then pour the marinara sauce over the entire mixture to coat everything thoroughly.
    Look for The sauce should cover the peppers and chicken, creating a uniform mixture ready for simmering.
    Tip There is no need to stir at this stage, as the sauce will naturally settle while cooking.

During the simmering phase, the kitchen should begin to smell like a classic Italian kitchen as the herbs and tomatoes heat up. The sauce will begin to bubble gently around the edges.

You should not see any signs of burning or aggressive boiling. If the sauce appears to be bubbling too vigorously, adjust your slow cooker to a lower setting to maintain a steady, gentle simmer that preserves the texture of the chicken.

Final check and service

  1. Slow cook and serve
    Cover the slow cooker and cook on high for 4 hours or low for 6 to 8 hours. Once the chicken reaches an internal temperature of 165°F (74°C), turn off the heat and let the stew rest for 5 minutes before serving in warm bowls.
    Look for The peppers should be very tender and the chicken cooked through with a rich, thick sauce texture.
    Safe temperature 165°F (74°C) internal temperature (poultry)
    Tip Use a digital meat thermometer to confirm the chicken is safely cooked.

The final phase is marked by the chicken reaching the safe internal temperature and the peppers achieving a tender, melt-in-your-mouth texture. The sauce should be thick and aromatic. Before serving, give the stew a gentle stir to combine all the ingredients. The final result should be a cohesive, vibrant stew where the individual components are distinct but perfectly coated in the savory tomato sauce.

Common mistakes

A common mistake is overcrowding the slow cooker, which can prevent the ingredients from cooking evenly or lead to excessive liquid buildup. Another error is cutting the chicken pieces into uneven sizes, which results in some pieces being overcooked while others remain underdone.

Do not lift the lid repeatedly during the cooking process, as every time you open it, heat escapes and the cooking time increases, potentially leading to inconsistent results and a longer wait time for your meal.

How to tell it’s done

The dish is considered done when the chicken pieces are fork-tender and have reached a minimum internal temperature of 165°F (74°C). The bell peppers should be soft and translucent, having absorbed the flavors of the tomato sauce.

If you notice the sauce is too thin, you can continue cooking it on the high setting with the lid removed for a short period to allow some of the liquid to evaporate, resulting in a richer, thicker stew consistency.
