What Makes This Recipe Special

This Slow Cooker Chicken Marsala stands out because it combines the rich, complex flavors of traditional Chicken Marsala with the ease and convenience of slow cooking. Instead of pan-searing and quickly simmering, the slow cooker allows the chicken to gently absorb the mushroom and herb-infused broth, resulting in tender meat that falls apart effortlessly. The use of dried thyme and oregano adds a rustic depth that complements the wine-inspired sauce without needing actual wine, making it accessible and pantry-friendly. Plus, optional thickening with cornstarch ensures the sauce has a luscious, velvety texture that clings perfectly to every bite. This method frees up your stove and lets you come home to an aromatic, restaurant-quality meal with almost no fuss.

Cook Slow Cooker Chicken Marsala Like This

Step 1: Prepare Your Ingredients

Start by slicing your mushrooms and chopping the onion into bite-sized pieces. Mince the garlic cloves finely so that their flavor infuses well. Season the chicken breasts with salt, pepper, thyme, and oregano evenly on both sides.

Step 2: Sauté Mushrooms and Onions

Heat the olive oil in a large skillet over medium heat. Add the onions and cook until they start to soften and become translucent, about 3-4 minutes. Toss in the sliced mushrooms and continue sautéing until they release their moisture and begin to brown, about 5-6 minutes. Add the minced garlic and cook for another 1 minute until fragrant. This step builds a deep flavor base that will elevate your Slow Cooker Chicken Marsala.

Step 3: Layer Ingredients in the Slow Cooker

Place the seasoned chicken breasts at the bottom of the slow cooker. Pour the sautéed mushroom and onion mixture evenly over the chicken. Next, pour in the chicken broth, ensuring the liquid covers the ingredients partially. This will keep the chicken moist and help develop the sauce.

Step 4: Slow Cook to Perfection

Cover the slow cooker with the lid and cook on low for 5-6 hours or on high for 3-4 hours. The chicken should be tender and cooked through, with the mushrooms and onions softened and flavorful.

Step 5: Optional – Thicken the Sauce

If you prefer a thicker sauce, mix the cornstarch with water in a small bowl to make a slurry. About 20 minutes before serving, stir the slurry gently into the slow cooker and replace the lid. Let it cook for the remaining 20 minutes on high to thicken up. Stir occasionally to prevent lumps.

Step 6: Serve and Enjoy

Once done, give the sauce a final stir, adjust seasoning with salt and pepper if needed, and serve hot. This dish pairs beautifully with mashed potatoes, rice, or pasta.

In-Season Flavor Ideas

• Add fresh herbs like chopped parsley or basil just before serving for a vibrant finish.
• Incorporate seasonal vegetables such as asparagus tips or baby carrots in the last hour of cooking for extra color and nutrition.
• Swap mushrooms for cremini or shiitake varieties to deepen the umami flavor during mushroom season.
• Serve alongside a fresh green salad with a lemon vinaigrette to brighten the meal.
• Pair with a side of garlic roasted potatoes or creamy polenta for a comforting feast.

What Not to Do

• Don’t skip sautéing the mushrooms and onions — this step is key to unlocking rich flavors.
• Avoid overcooking the chicken; slow cookers vary, so check tenderness to prevent it from drying out.
• Don’t add cornstarch slurry too early; it needs just 15-20 minutes to thicken properly without breaking down.
• Resist the temptation to lift the slow cooker lid too often, as it lets heat escape and lengthens cooking time.

Save for Later: Storage Tips

This Slow Cooker Chicken Marsala keeps well in the fridge for up to 4 days when stored in an airtight container. For longer storage, freeze portions in a freezer-safe container or bag for up to 3 months. When reheating, do so gently on the stove or microwave, adding a splash of chicken broth if the sauce has thickened too much. Avoid reheating multiple times to maintain texture and flavor.

Quick Questions

Can I use chicken thighs instead of breasts?

Can I make this recipe in an Instant Pot?

Yes, you can adapt this recipe for an Instant Pot by using the sauté function to cook the mushrooms and onions, then pressure cooking the chicken with broth for about 10 minutes. Use the sauté function again to thicken the sauce if desired.
