Before you start

Prepare the vegetables by slicing the bell peppers, onions, and mushrooms into consistent pieces to ensure even cooking. Ensure the chicken thighs are clean and ready. Have the slow cooker set up on a stable, heat-resistant surface near an electrical outlet.

Gather all measuring tools and the jar of marinara sauce so that the assembly process can be completed quickly and efficiently. Check that the slow cooker insert is clean and dry before beginning the layering process.

Ingredients at a glance (6)
  • 4 pieces bone-in chicken thighs
  • 1 cup sliced bell peppers
  • 1/2 cup sliced onions
  • 1 cup sliced mushrooms
  • 1 tbsp Italian seasoning
  • 24 oz marinara sauce

Instructions

Layering the chicken

  1. Layer the chicken
    Place the bone-in chicken thighs at the bottom of the slow cooker insert to ensure they are fully submerged in the sauce and cook evenly throughout the process.
    Look for The chicken is arranged in a single layer at the bottom of the cooker.
    Tip Pat the chicken dry with paper towels before adding to the cooker to remove excess surface moisture.

The chicken thighs should be arranged in a single layer at the base of the slow cooker, providing a stable foundation for the remaining ingredients. Ensure they are not stacked excessively, which allows for uniform heat penetration and consistent cooking.

The bottom of the insert should be clean and ready to receive the ingredients without any additional oil or fat, as the chicken will release its own juices during the slow cooking process.

Adding aromatics and seasoning

  1. Add vegetables and seasoning
    Scatter the sliced bell peppers, onions, and mushrooms over the chicken. Sprinkle the Italian seasoning evenly across the top to coat the ingredients effectively as the sauce simmers.
    Look for The vegetables form a colorful layer over the chicken base.
    Tip Keep the vegetable slices uniform in thickness to ensure they soften at the same rate.

The vegetables and seasoning should be distributed evenly over the chicken to ensure every bite is infused with flavor. The Italian seasoning should be sprinkled across the entire surface rather than in one spot. At this stage, the slow cooker is ready to receive the sauce, which will act as the braising liquid to keep the chicken and vegetables moist throughout the cooking cycle.

Slow cooking to completion

  1. Pour sauce and cook
    Pour the marinara sauce over the chicken and vegetables. Cover and cook on low for 4 to 6 hours or on high for 2 to 3 hours until the chicken reaches an internal temperature of 165°F (74°C). Let the chicken rest for 5 minutes before serving.
    Look for The sauce is bubbling and the chicken is tender and pulls away easily from the bone.
    Safe temperature 165°F (74°C) internal temperature (poultry)
    Tip Use a meat thermometer to verify the internal temperature of the thickest part of the thigh.

The dish is complete when the sauce is fragrant and the chicken is tender. The vegetables should be soft and fully incorporated into the sauce. Before serving, verify the internal temperature of the chicken has reached 165°F (74°C). The final dish should appear glossy, with the chicken pieces well-coated in the thick, savory sauce, ready to be plated and enjoyed immediately after the short resting period.

Common mistakes

A common mistake is overcrowding the slow cooker, which can prevent even heat distribution and lead to unevenly cooked chicken. Avoid lifting the lid frequently during the cooking process, as this releases heat and steam, significantly increasing the total cooking time and potentially drying out the chicken.

Ensure the chicken thighs are not layered too deeply, which can hinder the cooking process. Always verify the internal temperature of the chicken rather than relying solely on the clock, as cooking times can vary.

How to tell it’s done

The chicken is perfectly cooked when the meat is opaque throughout and pulls away easily from the bone with a fork. Using a digital meat thermometer inserted into the thickest part of the thigh, ensure it reaches an internal temperature of at least 165°F (74°C).

The sauce should be slightly thickened and aromatic, with the vegetables tender but not disintegrated. Allow the chicken to rest for at least 5 minutes before serving to ensure the juices redistribute throughout the meat.

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