Before you start

Ensure the slow cooker is placed on a level, heat-resistant surface near an outlet. Have all ingredients measured and ready to go. If the chicken thighs have excess fat, trim it away according to preference before starting.

Ensure that the cherry tomatoes are washed and sliced in half to help them release their juices during the cooking process. Having these simple steps completed beforehand makes the assembly phase incredibly quick and efficient, allowing for a seamless transition into the slow cooking process without any last-minute rushing or kitchen clutter.

Ingredients at a glance (4)
  • 4 lbs chicken thighs, bone-in or boneless
  • 1 pint cherry tomatoes, halved
  • 1 tbsp Italian seasoning
  • 1/2 cup basil pesto

Instructions

Assembly and Seasoning

  1. Prepare the Slow Cooker
    Place the raw chicken thighs into the basin of the slow cooker, ensuring they are laid flat to promote even heat distribution. Scatter the halved cherry tomatoes over the top of the chicken pieces.
    Look for Chicken should be arranged in a single layer if possible.
    Tip Removing excess moisture from the chicken with paper towels before placing can help the sauce adhere better.

At the end of this phase, the chicken thighs should be arranged in a single layer in the base of the slow cooker, covered with the halved cherry tomatoes, seasoned with Italian herbs, and topped with a generous layer of basil pesto. The ingredients should look organized and ready for the slow, steady heat. Verify that the slow cooker is plugged in and set to the low heat setting before covering it with the lid to begin the cooking process.

Slow Cooking Process

  1. Season and Add Pesto
    Sprinkle the Italian seasoning evenly over the chicken and tomatoes. Carefully pour the basil pesto over the entire mixture, using a spoon if necessary to ensure even coverage across all pieces.
    Look for Pesto should be distributed across all chicken thighs.
    Tip Use a silicone spatula to scrape the jar clean so no flavor is left behind.

During the cooking phase, the slow cooker will work to break down the connective tissues in the chicken and soften the tomatoes. The kitchen should begin to fill with the aromatic scent of basil, garlic, and herbs. Do not remove the lid during this phase, as the steam is essential for keeping the meat moist and tender. The food is ready to proceed when the cooking time has elapsed and the chicken is fully cooked through to a safe internal temperature.

Finishing and Serving

  1. Cook and Serve
    Cover the slow cooker and cook on low for 4 hours. Once finished, check the internal temperature of the chicken; it must reach 165°F (74°C) to be safe for consumption. Allow the chicken to rest for 5 minutes before serving.
    Look for Chicken is tender and pulls away easily from the bone.
    Safe temperature 165°F (74°C) internal temperature (poultry)
    Tip Check the temperature at the thickest part of the meat to ensure it is cooked through.

Once the cooking time is complete, the chicken should be tender and the sauce should have a glossy, thickened consistency. Use a thermometer to confirm the internal temperature of 165°F (74°C).

Allow the chicken to rest for at least 5 minutes before serving; this allows the juices to redistribute throughout the meat, ensuring maximum tenderness. Plate the chicken carefully, spooning the flavorful pesto and tomato sauce from the bottom of the slow cooker over each piece before serving.

Common mistakes

A common mistake is overcrowding the slow cooker, which can lead to uneven cooking and excess liquid accumulation. Arrange the chicken in a single layer to ensure proper heat circulation. Another error is checking the progress too often; every time the lid is lifted, heat escapes, extending the cooking time significantly.

Resist the urge to peek during the first three hours. Finally, ensure the chicken is fully defrosted before adding it to the slow cooker to maintain food safety and ensure the dish reaches the necessary temperature consistently.

How to tell it’s done

The chicken is perfectly done when the meat is opaque throughout and pulls away easily from the bone with a fork. Using a meat thermometer is the most accurate way to verify doneness; insert it into the thickest part of the thigh, ensuring it does not touch the bone.

The internal temperature must reach at least 165°F (74°C). The sauce should appear thickened and glossy, with the tomatoes having softened into the pesto mixture to create a cohesive, aromatic glaze that coats the chicken beautifully.

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