Before you start

Before beginning, ensure that all ingredients are measured and ready. Mince the garlic finely to allow its flavor to permeate the sauce evenly during the long cooking process. If you are using fresh peppers, slice them into uniform strips to ensure they soften at the same rate.

Prepare your workspace by clearing enough room for the slow cooker and ensuring your tongs are clean. If the chicken has been refrigerated, you can take it out of the fridge about 20 minutes before cooking to help it reach room temperature, though it is not strictly necessary for this method.

Ingredients at a glance (6)
  • 6 pieces boneless skinless chicken thighs
  • 2 cups red pepper strips
  • 1/2 cup green olives, pitted
  • 1 tbsp paprika
  • 3 cloves garlic, minced
  • 28 oz crushed tomatoes

Instructions

Preparation and Layering

  1. Assemble the Ingredients
    Place the raw chicken thighs into the base of the slow cooker, arranging them in a single layer to ensure even cooking. Scatter the red pepper strips and green olives over the top of the chicken pieces, ensuring they are distributed evenly throughout the insert.
    Look for Chicken should be arranged in a single layer at the bottom of the slow cooker.
    Tip Ensure the chicken is fully thawed before placing it into the slow cooker to maintain food safety and consistent cooking times.

At this stage, the chicken thighs should be arranged neatly at the bottom of the slow cooker, with the peppers and olives scattered evenly on top. The ingredients are raw, and the assembly is complete. Ensure no ingredients are stuck to the sides of the insert, as these may burn during the long cooking process.

Seasoning and Braising

  1. Season and Add Sauce
    Sprinkle the paprika and minced garlic evenly over the chicken and vegetables. Pour the crushed tomatoes over the entire mixture, ensuring everything is well-coated. Cover the slow cooker with its lid and set to cook on low for four hours or on high for two hours.
    Look for The mixture should be fully submerged or well-coated by the tomato sauce.
    Tip Using freshly minced garlic provides a more aromatic result than jarred alternatives, though both will work well in this long-cook method.

The dish is now covered and cooking. The aromas of garlic, paprika, and tomatoes should begin to fill the kitchen as the ingredients simmer together. You should see the tomato sauce bubbling gently, and the peppers will have begun to soften as they release their juices into the braising liquid.

Final Texture and Serving

  1. Final Braise and Serve
    Check the chicken for doneness by ensuring it is tender and easily pulled apart with tongs. Verify that the internal temperature of the chicken has reached at least 165°F (74°C). Allow the chicken to rest for at least 5 minutes before serving with the sauce.
    Look for The chicken should be soft and opaque throughout, with the sauce thickened.
    Safe temperature 165°F (74°C) internal temperature (poultry)
    Tip If the sauce appears too thin after cooking, remove the chicken and simmer the sauce on high for 15 minutes to reduce it.

The chicken is now tender, opaque, and fully cooked. The sauce has thickened, and the flavors have unified into a savory, cohesive dish. The chicken should be easily manipulated with tongs, and the internal temperature must be confirmed at 165°F (74°C) before you proceed to serve the dish to guests.

Common mistakes

A common mistake is overcrowding the slow cooker, which can prevent the chicken from cooking evenly and may result in a watery sauce. Always aim for a single layer of chicken to ensure maximum contact with the heat and the sauce.

Another error is checking the lid too frequently; every time the lid is removed, heat escapes and the cooking time increases significantly.

Try to resist the urge to peek until the final hour of cooking. Additionally, ensure you do not use frozen chicken, as it may not reach a safe temperature quickly enough in a slow cooker.

How to tell it’s done

The chicken is fully cooked when it is tender enough to be easily pierced by a fork or pulled apart with tongs. More importantly, use an instant-read thermometer to check the thickest part of the meat; the internal temperature must reach at least 165°F (74°C).

The sauce should be thickened and fragrant, with the peppers softened and the tomato base reduced to a rich consistency that clings to the chicken pieces. If the sauce is too thin, you can continue cooking on the high setting with the lid removed for a few minutes to evaporate excess moisture.

  • Poultry: 165°F (74°C) in the thickest part
