Before you start

Before starting, ensure all vegetables are washed and sliced uniformly to promote even cooking. Have the chicken thighs ready, patted dry, and kept in the refrigerator until the very last moment.

Prepare the slow cooker by placing it on a stable surface near an outlet, ensuring the area is clear of clutter to maintain kitchen safety throughout the preparation process.

Ingredients at a glance (6)
  • 4 pieces chicken thighs, bone-in and skin-on
  • 2 cups sliced bell peppers
  • 1 cup sliced onions
  • 1 tsp Espelette pepper
  • 1 cube crumbled bouillon
  • 2 cups crushed tomatoes

Instructions

Preparation and layering

  1. Assemble the base
    Place the raw chicken thighs into the bottom of the slow cooker. Scatter the sliced bell peppers and onions evenly over the top of the chicken pieces.
    Look for The chicken should be in a single layer at the bottom of the pot for even cooking.
    Tip Ensure the chicken is raw and cold from the refrigerator just before adding to the pot.

At this stage, the chicken is neatly arranged at the bottom of the slow cooker, topped with a colorful layer of sliced peppers and onions. The setup looks organized, and the ingredients are ready to receive the seasoning and tomato base that will transform them during the slow, gentle cooking process.

Seasoning and moisture

  1. Season and add liquid
    Sprinkle the Espelette pepper and the crumbled bouillon cube over the vegetables and chicken. Pour the crushed tomatoes over the entire mixture to ensure everything is well coated.
    Look for The tomatoes should cover the peppers and onions slightly to help them soften during the cooking process.
    Tip Crush the bouillon cube well between fingers to ensure even distribution of flavor throughout the dish.

The dish now smells aromatic as the Espelette pepper and bouillon cube are distributed.

The crushed tomatoes provide a deep red hue that covers the vegetables, signaling that the ingredients are ready to begin their slow transformation. Everything is properly submerged or coated to ensure even flavor distribution.

Slow simmering

  1. Slow cook until done
    Cover the slow cooker and cook on low for 4 hours. Once the time is up, check that the chicken has reached an internal temperature of 165°F (74°C). Allow the chicken to rest for at least 5 minutes before serving to ensure the juices redistribute properly.
    Look for The chicken meat should be tender and easily pulling away from the bone, and the sauce should be thickened and fragrant.
    Safe temperature 165°F (74°C) internal temperature (poultry)
    Tip Use a meat thermometer inserted into the thickest part of the thigh to confirm the safe temperature.

After hours of cooking, the kitchen is filled with a savory, comforting scent. The chicken is tender, the vegetables have softened significantly into the tomato sauce, and the entire dish is bubbling gently. A quick temperature check confirms the chicken is cooked through and ready to be served.

Common mistakes

Avoid over-crowding the slow cooker, as this can lead to uneven cooking and excess liquid. Do not lift the lid repeatedly during the cooking process, as this releases heat and moisture, significantly increasing the total cooking time.

Additionally, ensure the chicken is not left out at room temperature for more than thirty minutes before it goes into the pot to maintain food safety standards.

How to tell it’s done

The chicken is fully cooked when the meat is opaque throughout and pulls easily away from the bone. Use a meat thermometer to confirm the chicken has reached an internal temperature of at least 165°F (74°C).

The vegetables should be very soft, and the sauce should have thickened into a rich, flavorful consistency that coats the back of a spoon.

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