1-First Step: Prepare and Brown the Chicken Start by lightly coating a large slow cooker with nonstick spray to prevent sticking. Heat 1 tablespoon of olive oil in a skillet over medium-high heat, then season 2 pounds of boneless skinless chicken breasts or thighs with 1 teaspoon salt and ½ teaspoon black pepper. Brown the chicken on both sides for 3-4 minutes on the first side and about 2 minutes on the other, which adds flavor and seals in juices. For a vegetarian twist, you could adapt this by using plant-based protein, but here it’s all about that classic chicken taste. Transfer the browned chicken to the slow cooker for the next stage.

2-Second Step: Sauté the Aromatics Reduce the skillet heat to medium and wipe it out with a paper towel, then add the remaining 2 teaspoons of olive oil. Sauté 1 medium chopped yellow onion until it begins to soften, about 3 minutes, to build a flavorful base. Next, add 3 cloves of minced garlic and 1 tablespoon of balsamic vinegar, cooking for 1 more minute until fragrant and the vinegar reduces slightly. This step infuses the dish with essential aromas; if you’re watching sodium, use low-sodium options where possible. Transfer this mixture, including the pan drippings, to the slow cooker on top of the chicken.

3-Third Step: Add the Remaining Ingredients and Cook Now, add 28 ounces of crushed tomatoes, 1 medium chopped green bell pepper, 8 ounces of sliced baby bella cremini mushrooms, and 2 teaspoons of Italian seasoning to the slow cooker. For dietary needs, you might swap mushrooms for other veggies if preferred. Cover and cook: for chicken breasts, use high for 1½ to 2½ hours or low for 4 to 5 hours; for chicken thighs, high for 3 to 4 hours or low for 5 to 6 hours. Check that the chicken reaches an internal temperature of 165 degrees F for safety. This chicken pot pie pasta recipe on our site offers a similar comforting vibe if you want more ideas.

4-Fourth Step: Thicken the Sauce and Finish Once cooking is done, remove the chicken and chop or shred it if desired, which makes it easier to serve. To thicken the sauce, uncover the slow cooker and cook on high for about 1 hour, allowing flavors to develop fully. Stir in the remaining ½ teaspoon of balsamic vinegar and season to taste with salt and pepper for that perfect balance. If you prefer a quicker thicken, mix a cornstarch slurry with 1 tablespoon cornstarch, 1 tablespoon water, and 1 tablespoon of sauce, then stir it in. Return the chicken to the sauce, toss to combine, and warm through if needed.
