Ingredients

  

• 2 to 2.5 pounds boneless, skinless chicken thighs (or breasts), trimmed
• 1 teaspoon kosher salt, plus more to taste
• 1/2 teaspoon black pepper
• 1 teaspoon garlic powder
• 1 teaspoon dried thyme (or 1 tablespoon fresh, chopped)
• 1/2 teaspoon dried oregano
• 2 tablespoons olive oil or butter (for browning)
• 1 large yellow onion, thinly sliced
• 3 cloves garlic, minced
• 16 ounces cremini or button mushrooms, sliced
• 3/4 cup dry Marsala wine (not sweet)
• 1 cup low-sodium chicken broth
• 2 tablespoons tomato paste
• 1 tablespoon Dijon mustard
• 1 bay leaf
• 1/3 cup heavy cream (or half-and-half for lighter)
• 2 tablespoons cornstarch mixed with 2 tablespoons cold water
• Fresh parsley, chopped, for garnish
• Optional: 1 to 2 tablespoons unsalted butter to finish the sauce

Instructions

 

• Season the chicken. Pat the chicken dry and season both sides with salt, pepper, garlic powder, thyme, and oregano.
• Brown for flavor. Heat the olive oil or butter in a skillet over medium-high heat. Sear the chicken 2–3 minutes per side until golden. You’re not cooking through—just building flavor. Transfer to the slow cooker.
• Soften the aromatics. In the same skillet, add the onions and mushrooms with a pinch of salt. Sauté 3–4 minutes until they release moisture and start to brown. Stir in the garlic for 30 seconds. Transfer everything to the slow cooker.
• Build the sauce. Whisk Marsala, chicken broth, tomato paste, and Dijon until smooth. Pour over the chicken and vegetables. Add the bay leaf.
• Cook low and slow. Cover and cook on LOW for 4–5 hours or on HIGH for 2.5–3 hours, until the chicken is tender.
• Thicken. Remove the bay leaf. Stir in the cornstarch slurry, then the cream. Cover and cook on HIGH for 10–15 minutes until the sauce thickens slightly and turns glossy.
• Finish and taste. For extra richness, stir in the butter. Taste and adjust salt and pepper.
• Serve. Spoon the chicken and mushrooms over mashed potatoes, buttered egg noodles, polenta, or rice. Garnish with chopped parsley.

Why This Recipe Works

Save

This recipe leans on Marsala wine for depth and subtle sweetness, which pairs beautifully with mushrooms and chicken. The slow cooker gently simmers the sauce, letting flavors meld and the chicken stay juicy.

Browning the chicken first adds rich flavor and helps the sauce cling better. A cornstarch slurry at the end gives you that restaurant-quality glossy sauce without fuss. It’s low effort with a high payoff, and it reheats like a dream.

Ingredients

• 2 to 2.5 pounds boneless, skinless chicken thighs (or breasts), trimmed
• 1 teaspoon kosher salt, plus more to taste
• 1/2 teaspoon black pepper
• 1 teaspoon garlic powder

How to Make It

Save

1. Season the chicken. Pat the chicken dry and season both sides with salt, pepper, garlic powder, thyme, and oregano.
2. Brown for flavor. Heat the olive oil or butter in a skillet over medium-high heat.

   Sear the chicken 2–3 minutes per side until golden. You’re not cooking through—just building flavor. Transfer to the slow cooker.

3. Soften the aromatics. In the same skillet, add the onions and mushrooms with a pinch of salt.

   Sauté 3–4 minutes until they release moisture and start to brown. Stir in the garlic for 30 seconds. Transfer everything to the slow cooker.

4. Build the sauce. Whisk Marsala, chicken broth, tomato paste, and Dijon until smooth.

   Pour over the chicken and vegetables. Add the bay leaf.

5. Cook low and slow. Cover and cook on LOW for 4–5 hours or on HIGH for 2.5–3 hours, until the chicken is tender.
6. Thicken. Remove the bay leaf. Stir in the cornstarch slurry, then the cream.

   Cover and cook on HIGH for 10–15 minutes until the sauce thickens slightly and turns glossy.

7. Finish and taste. For extra richness, stir in the butter. Taste and adjust salt and pepper.
8. Serve. Spoon the chicken and mushrooms over mashed potatoes, buttered egg noodles, polenta, or rice. Garnish with chopped parsley.

Storage Instructions

• Refrigerate: Cool completely, then store in an airtight container for up to 4 days.
• Freeze: Freeze in portions for up to 3 months.

  The sauce may separate slightly; stir while reheating to bring it back together.

• Reheat: Warm gently on the stovetop over medium-low heat or in the microwave at 50–70% power. Add a splash of broth or water if the sauce thickens too much.

Why This is Good for You

Chicken thighs provide lean protein that keeps you full and supports muscle health. Mushrooms bring fiber, B vitamins, and antioxidants, adding earthy flavor without heavy calories.

Cooking low and slow means less need for extra fats, while the sauce gets body from mushrooms and aromatics instead of relying solely on cream. You control the sodium and the quality of ingredients, making this a smarter, satisfying comfort meal.

What Not to Do

• Don’t skip browning the chicken. It adds big flavor and better texture.
• Don’t use sweet Marsala. Choose dry Marsala to avoid a sugary sauce.
• Don’t add the cream early. Dairy can curdle with long cooking. Stir it in at the end.
• Don’t overcook on high. High heat for too long can make chicken stringy.

  Low and steady is best.

• Don’t crowd with extra liquid. Mushrooms release moisture. Stick to the listed amounts for a balanced, flavorful sauce.

Alternatives

• Chicken options: Use boneless, skinless breasts if you prefer. Reduce cook time slightly and check for doneness early so they stay juicy.
• Mushrooms: Cremini, baby bella, or a mix with shiitake for extra depth.

  Keep total volume around 16 ounces.

• Dairy-free: Swap cream for full-fat coconut milk or leave it out and add an extra teaspoon of cornstarch for thickness.
• Gluten-free: This recipe is naturally gluten-free as written; confirm your Dijon and broth are certified GF.
• No alcohol: Replace Marsala with a mix of 1/2 cup extra chicken broth, 2 tablespoons balsamic vinegar, and 1 tablespoon Worcestershire. Flavor will differ but stays savory and rich.
• Herbs: Fresh thyme or rosemary works beautifully. Add at the start, and finish with parsley.
• Finishing touch: Stir in a squeeze of lemon to brighten the sauce right before serving.

FAQ

Can I make this without searing the chicken first?

Yes, you can, but you’ll lose some depth of flavor and color.

If skipping the sear, add 1 extra teaspoon of olive oil and a pinch more salt to the slow cooker to help carry the flavors.

What’s the best Marsala to use?

Use dry Marsala for a balanced, savory sauce. Sweet Marsala makes the dish taste sugary. You don’t need an expensive bottle—just one labeled “dry.”

How do I know when the chicken is done?

It should be tender and easily pulled with a fork.

Internal temperature should reach 165°F. In a slow cooker, thighs take about 4–5 hours on low; breasts may be done a bit sooner.

Can I thicken the sauce without cornstarch?

Yes. You can reduce the sauce by simmering it briefly on the stovetop after cooking, or use 2 tablespoons of flour whisked into 2 tablespoons of cream and stir it in at the end.

What should I serve with it?

Mashed potatoes, polenta, buttered egg noodles, or rice are all great.

For something lighter, try cauliflower mash or steamed green beans on the side.

Can I add vegetables?

Absolutely. Add sliced carrots or halved baby potatoes at the bottom of the slow cooker before the chicken. Keep mushrooms and onions as listed so the sauce stays balanced.

How do I prevent a watery sauce?

Stick to the liquid amounts and sauté the mushrooms first to drive off moisture.

Thicken at the end with the cornstarch slurry and finish uncovered for a few minutes if needed.

Is this good for meal prep?

Yes. It holds up well for several days and reheats gently without drying out. Keep the starch (potatoes, pasta, or rice) separate until serving.
