Before you start

Before beginning, ensure your slow cooker is clean and positioned on a stable, heat-resistant surface away from the edge of the counter. Prepare the onion by peeling and dicing it into uniform pieces to ensure even softening.

Gather the remaining ingredients so they are ready for immediate use. Check that you have an instant-read thermometer available to verify that the chicken is cooked through to the safe internal temperature of 165°F (74°C) before you begin the final serving process.

Ingredients at a glance (6)
  • 6 pieces bone-in skinless chicken thighs
  • 1 medium yellow onion, diced
  • 1/2 tsp black pepper
  • 1 tsp garlic powder
  • 28 oz crushed tomatoes
  • 1/2 cup chicken broth

Instructions

Layering the Slow Cooker

  1. Prepare the Chicken
    Place the bone-in skinless chicken thighs into the slow cooker basin in a single layer. Ensure the chicken is evenly distributed across the bottom of the cooker to promote uniform cooking throughout the process.
    Look for The chicken pieces should sit flat at the bottom of the slow cooker insert.
    Tip Removing excess surface moisture from the chicken with paper towels before placing it in the cooker can prevent the sauce from becoming too thin.

The chicken should be arranged in a single layer at the bottom of the slow cooker basin. Ensure the pieces are not overlapping excessively to allow for even heat distribution.

This foundational step is critical for ensuring the chicken cooks uniformly throughout the long braising process, creating the perfect environment for the meat to become tender and absorb the surrounding flavors of the tomato gravy.

Seasoning and Aromatics

  1. Season and Add Aromatics
    Scatter the diced yellow onion evenly over the chicken thighs. Sprinkle the black pepper and garlic powder over the onion and chicken to ensure an even distribution of seasoning across the entire surface of the meat.
    Look for The onion should be spread out rather than piled in one spot.
    Tip Use a fresh, sharp knife to dice the onion finely so it softens completely during the long braise.

The diced onion, black pepper, and garlic powder should be distributed evenly across the chicken. Check that the onion pieces are spread out rather than clustered, as this helps them soften evenly. The seasoning should cover the surface of the chicken to ensure every bite is flavorful. Once seasoned, the chicken is ready for the final addition of liquids before starting the slow cooking cycle.

Braising and Finishing

  1. Combine Sauce and Cook
    Pour the crushed tomatoes and chicken broth over the seasoned chicken. Cover the slow cooker with the lid and cook on low for 6 hours until the chicken reaches an internal temperature of 165°F (74°C). Allow the chicken to rest for 5 minutes before serving.
    Look for The tomato gravy should be thick and the chicken should be fork-tender.
    Safe temperature 165°F (74°C) internal temperature (poultry)
    Tip Check the temperature at the thickest part of the thigh, avoiding the bone for an accurate reading.

The crushed tomatoes and broth should be poured over the chicken, fully submerging the base of the thighs. At the end of the cooking time, the gravy should be thick and aromatic, and the chicken should be tender. Verify the internal temperature of 165°F (74°C) before allowing the dish to rest for 5 minutes, which helps the juices redistribute within the meat for a more succulent result.

Common mistakes

A common error is overcrowding the slow cooker, which can prevent the heat from circulating evenly and lead to unevenly cooked chicken. Ensure the thighs are arranged in a single layer for the best results.

Another mistake is lifting the lid frequently during the cooking process; every time the lid is opened, heat escapes, which significantly increases the total cooking time and affects the consistency of the gravy. Resist the urge to peek until the final hour of the cooking cycle.

How to tell it’s done

The chicken is done when it reaches an internal temperature of 165°F (74°C) when measured with a food thermometer inserted into the thickest part of the thigh, avoiding the bone.

Visually, the meat should pull away slightly from the bone, and the gravy should have thickened into a rich, cohesive sauce that coats the back of a spoon. If the meat does not pull away easily or the temperature is below the safe threshold, continue cooking for another 20 minutes.

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