Chicken Marsala is the kind of Italian-American restaurant dish that feels fancy but is secretly simple, and this slow cooker version proves it. Boneless chicken breasts simmer for hours in a savory marsala wine sauce loaded with golden mushrooms, garlic, and thyme until the meat is fork-tender and the sauce is glossy and deep amber.

The trick is a quick skillet sear before everything goes into the crockpot. That five-minute step builds the browned fond that gives the sauce its restaurant-quality flavor, and the slow cooker does the rest while you go about your day. A splash of cream stirred in at the very end turns the pan juices silky without making the dish heavy.
Serve it over buttered egg noodles, creamy mashed potatoes, or crusty bread to soak up every drop of sauce. It is elegant enough for a dinner party and easy enough for a Tuesday.
Why You'll Love This Recipe
About the Ingredients
6 boneless, skinless chicken breasts (about 2 pounds / 900g), pounded to 1/2-inch thickness
Pounding to an even thickness ensures they cook through without drying out. If you prefer dark meat, substitute 6 boneless, skinless chicken thighs and add 30 minutes of cook time.
1/2 cup (60g) all-purpose flour, for dredging
Flour helps the chicken brown and thickens the sauce as it cooks. For a gluten-free version, use 1/4 cup cornstarch instead and whisk the sauce well before serving.
1 1/2 teaspoons kosher salt, divided
Kosher salt seasons more evenly than table salt because of its larger flakes. If using fine table salt, reduce to 1 teaspoon total.
1/2 teaspoon freshly ground black pepper
Fresh-cracked pepper has far more aroma than pre-ground. Buy whole peppercorns and grind them just before using for the best flavor.
3 tablespoons olive oil, divided
Olive oil handles the high skillet heat needed for a good sear. Avocado oil is a great substitute if you want an even higher smoke point.
12 ounces (340g) cremini mushrooms, sliced 1/4-inch thick
Cremini (baby bella) mushrooms have more flavor than white buttons. Buy them dry and firm with no slimy spots, and brush clean rather than soaking them.
4 garlic cloves, minced
Fresh garlic gives the sauce its backbone. If you are out, use 1 teaspoon garlic powder stirred in with the broth instead of minced cloves.
1 cup (240ml) dry marsala wine
Dry marsala is the star of this dish, so choose a good drinking-quality bottle, not cooking wine. No marsala on hand? Substitute dry sherry plus 1 teaspoon honey.
3/4 cup (180ml) low-sodium chicken broth
Low-sodium broth lets you control the seasoning. Vegetable broth works fine as a substitute for a lighter, slightly sweeter sauce.
1/2 cup (120ml) heavy cream
Heavy cream gives the sauce its silky finish. For a lighter version, use half-and-half but whisk it in off the heat so it does not curdle.
1 teaspoon chopped fresh thyme leaves, plus more for garnish
Fresh thyme pairs beautifully with mushrooms. Dried thyme works too; use 1/2 teaspoon and add it with the broth.
2 tablespoons chopped fresh parsley, for garnish
Flat-leaf parsley adds a bright, fresh finish. If you only have curly parsley, chop it finely so it does not overwhelm the sauce.
Tips & Tricks
Do not skip the sear
Browning the chicken and mushrooms in a hot skillet before slow cooking builds the fond that gives the sauce its deep, savory flavor. Skipping it leaves you with a flat, watery sauce.
Add the cream at the very end
Stirring cream in during the last 10 minutes keeps it from separating or curdling during the long cook. Let the sauce come together first, then finish it gently.
Do not overcook the chicken
Breasts are done when they reach 165F (74C). Check them at the earliest cook time rather than letting them sit on warm for an extra hour, which dries them out.
Thicken the sauce if needed
Slow cookers trap moisture, so the sauce can be thin. Whisk 1 tablespoon cornstarch with 1 tablespoon cold water and stir it in during the last 15 minutes on High.
Pro Tips
Step-by-Step Instructions
1. Pound and Season
Place each chicken breast between two sheets of plastic wrap and pound to an even 1/2-inch thickness. Pat dry and season both sides with 1 teaspoon of the salt and the pepper.
2. Dredge the Chicken
Spread the flour on a shallow plate and dredge each breast, shaking off the excess so only a thin coating remains. A thin coat browns cleanly and thickens the sauce without turning gluey.
3. Sear the Chicken
Heat 2 tablespoons olive oil in a large skillet over medium-high heat (about 375F / 190C) and sear the chicken in batches for 2 to 3 minutes per side until golden brown. Transfer to the slow cooker.
4. Brown the Mushrooms
Add the remaining 1 tablespoon oil to the skillet and cook the mushrooms, undisturbed, for 4 to 5 minutes until deeply golden and their edges begin to crisp. Add the garlic and thyme and stir for 30 seconds until fragrant.
5. Deglaze with Marsala
Pour in the marsala and simmer for 2 minutes, scraping up the browned bits from the bottom of the skillet. The liquid should reduce slightly and smell of wine and mushrooms, not raw alcohol.
6. Load the Slow Cooker
Pour the mushroom mixture and chicken broth over the chicken in the slow cooker and add the remaining 1/2 teaspoon salt. Cover and cook on Low for 4 to 5 hours or on High for 2 to 2.5 hours.
7. Finish with Cream
Stir in the heavy cream during the last 10 minutes of cooking and let it heat through until the sauce is silky and coats the back of a spoon. Taste and adjust the salt.
8. Garnish and Serve
Sprinkle with fresh parsley and extra thyme and serve hot over egg noodles, mashed potatoes, or crusty bread. Spoon plenty of sauce over each portion.
Delicious Variations
Mushroom Medley
Swap half the cremini for shiitake or oyster mushrooms for a deeper, woodsier flavor and a more varied texture.
Lightened-Up Version
Use half-and-half instead of heavy cream and serve over cauliflower rice to cut the carbs and calories.
Chicken Marsala Pasta
Slice the cooked chicken, toss it with the sauce and 12 ounces of cooked fettuccine, and finish with grated parmesan.
How to Store Slow Cooker Chicken Marsala
Refrigerator
Store leftovers in an airtight container in the refrigerator for up to 4 days. Keep the chicken submerged in the sauce so it stays moist.
Freezer
Freeze the chicken and sauce together in a freezer-safe container for up to 3 months. Thaw overnight in the refrigerator before reheating.
Reheating
Reheat gently on the stovetop over low heat or in the microwave in 30-second bursts, adding a splash of broth if the sauce has thickened too much.
Frequently Asked Questions
Q: Can I make slow cooker chicken marsala without wine?
Yes, you can replace the marsala with an equal amount of chicken broth plus 2 tablespoons balsamic vinegar and 1 teaspoon honey. The sauce will be slightly less complex but still rich and savory. For a fully alcohol-free version, use a good-quality marsala cooking wine labeled alcohol-free.
Q: Do I have to brown the chicken before slow cooking it?
Browning is strongly recommended because it creates the deep flavor base for the sauce. If you are short on time, you can skip it, but add 1 tablespoon tomato paste and a pinch of sugar to the slow cooker to compensate for the missing caramelized flavor.
Q: How do I keep the chicken from drying out in the slow cooker?
Cook on Low for no more than 5 hours and check the internal temperature, which should read 165F (74C). Pounding the breasts to an even thickness and keeping them submerged in the sauce also helps them stay juicy.
Q: Can I use frozen chicken breasts in this recipe?
No, frozen chicken should not go into a slow cooker because it spends too long in the temperature danger zone. Thaw the chicken completely in the refrigerator overnight before dredging and searing it.
Q: What is the best way to serve chicken marsala?
Serve it over buttered egg noodles, mashed potatoes, or polenta, all of which soak up the creamy sauce beautifully. Crusty bread and a simple green salad round out the meal.
