Start by heating a little oil in a large pan over medium-high heat. You want the pan hot before the chicken goes in so it sears instead of steaming.
Add the chicken skin-side down and let it cook undisturbed for about 3 minutes. Once it hits the pan, you should hear that sizzle right away.
Flip and sear the other side for another 3 minutes, until lightly golden. This step is optional, but it adds more flavor to the sauce later.
Add the potatoes to the bottom of your slow cooker and spread them out in an even layer so they cook through properly.
Place the chicken over the potatoes, then add the onion, garlic, red pepper, carrot, tomatoes, tomato paste, herbs, and seasonings on top. No need to make it look perfect here.
Pour in the red wine, if using. At this point, everything is ready to cook.
Cover and cook on high for 4 hours or low for 8 hours, until the chicken is tender and the potatoes are cooked through.
Add the mushrooms and olives during the last 30 minutes of cooking so they keep their texture and don’t get too soft.
Let everything finish cooking, then gently stir so the mushrooms and olives settle into the sauce.
Spoon the chicken cacciatore into bowls or plates and finish with fresh parsley, if you like.
Serve warm as-is. Or over pasta or spaghetti squash for a more complete meal.
The chicken should be tender enough to pull apart easily with a fork, with the sauce coating everything underneath.

Notes
This recipe is pretty forgiving, but a few small details can make a difference in how it turns out.If you have time, browning the chicken first adds a deeper flavor to the sauce. It’s not required, but it does give you a better base. Just make sure the pan is hot and don’t overcrowd it, otherwise the chicken will steam instead of sear.The potatoes are what make this a full meal, so how you cut them matters. Baby potatoes can be halved or left whole, while larger ones should be cut into even chunks so they cook through at the same time.A few extra things to keep in mind:
The sauce may look a little thin at first, but it thickens slightly as it cooks and settles.
Avoid adding extra liquid, the chicken and tomatoes release enough as they cook.
Red wine adds depth, but you can skip it or replace it with a splash of stock.
Taste and adjust salt at the end, especially depending on your tomatoes and olives.
Leftovers keep really well and taste even better the next day.
This is one of those recipes that doesn’t need much adjusting once you get the basics right. It comes together on its own and is easy to make work with what you have.
