Here’s the rundown of everything you’ll need. Don’t be intimidated by the list; it’s mostly pantry staples and straightforward fresh ingredients!

For the Chicken & Initial Seasoning:

• 2.5 pounds boneless, skinless chicken breasts or thighs – Use what you love! Thighs will be a bit more tender and flavorful, but breasts work beautifully too.
• 1 ¼ teaspoons kosher salt
• ¾ teaspoon ground black pepper

Aromatics & Vegetables:

• 1 large yellow onion, chopped
• 1 large green bell pepper, chopped
• 10 ounces sliced baby bella (cremini) mushrooms – These add such a lovely earthy depth.
• 4 cloves garlic, minced – Don’t skimp on the garlic!

Sauce Components:

• 1 can (28 ounces) crushed tomatoes – The heart of our rich sauce.
• 1 can (10 ounces) diced tomatoes with green chilies, undrained – My little secret for an extra layer of flavor!
• 2 ½ teaspoons Italian seasoning
• 1 bay leaf

Fats & Liquids for Cooking:

• 1 tablespoon plus 1 teaspoon extra-virgin olive oil (for searing chicken)
• 2.5 teaspoons extra-virgin olive oil (for sautéing aromatics)
• 1 tablespoon plus 1 teaspoon balsamic vinegar (for deglazing/cooking) – Adds a wonderful tangy sweetness.

Finishing & Serving:

• ¾ teaspoon balsamic vinegar (for finishing sauce) – This little bit at the end brightens everything up.
• Chopped fresh parsley (for garnish) – A pop of color and freshness!
• Serving suggestions: Whole wheat pasta, brown rice, creamy polenta, simple rice, zucchini noodles, or baked and shredded spaghetti squash.

Let’s Get Cooking: Step-by-Step to Cacciatore Bliss

Alright, ready to make some magic? Here’s how:

1. Sear the Chicken: First things first, lightly grease the insert of your slow cooker. Now, grab a spacious skillet and warm 1 tablespoon plus 1 teaspoon of olive oil over medium-high heat. While that’s heating, generously season your chicken pieces on all sides with the kosher salt and ground black pepper. Once the oil is shimmering, carefully place the chicken in the hot skillet. Don’t overcrowd the pan – work in batches if you need to. Let the chicken cook for 4-5 minutes on the first side until it gets a beautiful deep golden crust (try not to move it around too much!). Flip it over and brown the other side for about 2-3 minutes. Transfer that gorgeous seared chicken to your prepared slow cooker.
2. Sauté Aromatics: Lower the heat under your skillet to medium. If there are a lot of browned bits stuck to the bottom (the good stuff, mostly!), you can carefully wipe it out with a paper towel if it looks like it might burn. Add the remaining 2.5 teaspoons of olive oil. Once it’s warm, toss in the chopped onion and cook for about 3-4 minutes, just until it starts to soften. Now, stir in the minced garlic and 1 tablespoon plus 1 teaspoon of balsamic vinegar. Keep that going for another 60-90 seconds – you’ll smell that amazing garlic, and the vinegar will reduce just a tad. Scrape all of this (and any yummy pan drippings!) into the slow cooker with the chicken.
3. Combine and Slow Cook: Time to build the sauce! Pour the crushed tomatoes, the undrained can of diced tomatoes with green chilies, the chopped green bell pepper, sliced mushrooms, Italian seasoning, and the bay leaf right on top of the chicken in the slow cooker. Pop the lid on.

• If you’re using chicken breasts, cook on LOW for 4.5 to 5.5 hours or on HIGH for 2 to 3 hours. You’re looking for the chicken to be tender and reach an internal temperature of 165∘F (74∘C).
• If you’re using chicken thighs, cook on LOW for 5.5 to 6.5 hours or on HIGH for 3.5 to 4.5 hours, until they’re thoroughly cooked to 165∘F (74∘C). Once the chicken is perfectly cooked, gently take it out of the slow cooker. You can serve the pieces whole, or if you prefer, shred or chop the chicken. And don’t forget to find and toss that bay leaf!

4. Finish Sauce & Serve: Now, for that extra flavor boost! If you have the time (and I highly recommend it!), remove the lid from the slow cooker and switch the setting to HIGH. Let the sauce simmer and reduce for 45 to 60 minutes. This really intensifies the flavors and gives you a richer, more luscious sauce. Just before you’re ready to serve, stir in that remaining ¾ teaspoon of balsamic vinegar. Give the sauce a taste – does it need a tiny bit more salt or pepper? Adjust it to your liking. If you’ve shredded or chopped your chicken, add it back to the sauce now and give it a good stir to coat and warm through. If you’re serving the chicken pieces whole, plate them up and generously spoon that amazing sauce right over the top. Serve it hot with your favorite side (I’m a sucker for creamy polenta with this!) and a sprinkle of fresh chopped parsley.

My Top Tips for Success

• Don’t Skip the Sear! I know it’s an extra step, but browning the chicken first adds so much flavor. It creates those delicious caramelized bits that make the sauce extra special.
• Choose Your Chicken: Thighs tend to stay more moist and become incredibly tender in the slow cooker, but breasts work great too, especially if you’re watching fat content. Just be mindful of the cooking times.
• Sauce Thickness: If you like an even thicker sauce after the reduction time, you can make a small slurry with a tablespoon of cornstarch and two tablespoons of cold water, then stir it into the simmering sauce for the last 15-20 minutes of thickening.
• Spice it Up (or Down): The diced tomatoes with green chilies add a mild warmth. If you like more heat, feel free to add a pinch of red pepper flakes with the Italian seasoning. If you’re sensitive to spice, you can use regular diced tomatoes instead.
• Storage Savvy: Leftovers are fantastic! Store them in an airtight container in the refrigerator for up to 3-4 days. This dish also freezes beautifully for up to 3 months. Just thaw overnight in the fridge and reheat gently.

Perfect Pairings & Serving Ideas

This Rich & Rustic Slow Cooker Chicken Cacciatore is wonderfully versatile. Here are some of my favorite ways to serve it:

• Classic Comfort: Over a bed of creamy polenta (my personal favorite!), pappardelle pasta, or even just simple rice to soak up all that delicious sauce.
• Low-Carb Love: Serve it with zucchini noodles (“zoodles”), spaghetti squash, or cauliflower rice. A side of steamed green beans or a simple green salad would be perfect too.
• Bread is Your Friend: You’ll definitely want some crusty bread on the side for mopping up every last bit of that incredible sauce. Garlic bread would be next level!
• Wine Time: A medium-bodied Italian red wine like a Chianti or a Sangiovese complements the rustic flavors beautifully.

This dish is perfect for a cozy Sunday dinner, a satisfying weeknight meal that feels a bit special, or even for meal prepping lunches for the week.
