The complex aroma comes from onions, peppers, garlic, and tomatoes simmering together with tender chicken. You don’t need to babysit it, and the flavors still taste bright and comforting. If you’re after a reliable chicken dinner that can feed four and leave you the time to do other things, this recipe will be a steady friend.

Ingredients for this Slow Cooker Chicken Cacciatore

1.5 pounds bone-in, skin-on chicken thighs
1 medium yellow onion, sliced
1 red bell pepper, sliced
1 green bell pepper, sliced
3 cloves garlic, minced
1 can (28 oz) crushed tomatoes
1/2 cup low-sodium chicken broth
1/2 cup sliced mushrooms
1 teaspoon dried oregano
1 teaspoon dried thyme
1 teaspoon crushed red pepper flakes (optional)
2 tablespoons olive oil
1 cup pitted green olives (optional)
Salt and black pepper to taste

Tips: If you don’t like olives, feel free to leave them out. If you prefer a milder flavor, skip the red pepper flakes. You can swap in chicken breast, but thighs stay juicier in slow cooking.

Instructions

Season the chicken thighs with a pinch of salt and pepper. In a large skillet over medium-high heat, brown the chicken on both sides in a tablespoon of olive oil. This step adds color and depth, even though you’ll finish cooking in the slow cooker.
Transfer the browned chicken to the slow cooker. In the same skillet, sauté the onion and peppers for 3–4 minutes until they start to soften. Add garlic and cook for another 30 seconds.
Pour in the crushed tomatoes and chicken broth to loosen the fond from the pan. Stir in oregano, thyme, and red pepper flakes if using. Let it simmer for 1–2 minutes, then pour this mixture over the chicken in the slow cooker.
Scatter the mushrooms and olives over the top. Cover and cook on low for 6–7 hours or until the chicken is tender and falls easily from the bone.
Taste and adjust seasoning with salt and pepper. If you like a thicker sauce, remove the lid for the last 15–20 minutes of cooking to reduce a bit, or stir in a teaspoon of cornstarch slurry if you’re in a rush.
Serve warm, spooning the sauce over the chicken and pairing with crusty bread, polenta, or pasta. A light sprinkle of fresh parsley or grated parmesan can finish the dish nicely.

Nutritional information

Estimated per serving: about 350 calories. The dish provides a balance of protein from the chicken, fiber from the vegetables, and a modest amount of fat from olive oil. If you’re watching sodium, you can use a low-sodium broth and skip extra salt until you’ve tasted the final sauce, since canned tomatoes can vary in salt content.

Frequently asked questions

1. Can I use chicken breasts instead of thighs?

Yes, you can. Chicken breasts will cook faster and can dry out a bit more in slow cooking, so I’d recommend checking for doneness around the 5–6 hour mark and removing them once they’re just cooked through. Return the breast pieces to the sauce to keep them from drying out if you plan to reheat leftovers.

2. Can I freeze leftovers?

Absolutely. Cool the leftovers, portion them, and freeze in airtight containers. Thaw overnight in the fridge before reheating gently on the stove or in the microwave. The flavors often improve after a night in the fridge, too.

3. What can I serve with this dish?

This cacciatore is great with pasta, polenta, or a slice of crusty bread to soak up the sauce. A simple side salad or steamed greens also pairs nicely to balance the meal.
