This one-dish wonder brings Italian comfort to your dinner table with minimal effort. I developed this recipe during busy service nights at The Smoky Pig, needing something hearty yet simple for staff meals.
The chicken stays tender while the marsala sauce reduces to a rich, velvety consistency. Layering everything in one dish means the flavors meld together beautifully as it bakes.
You’ll end up with a golden, bubbling casserole that’s restaurant-quality without the fuss. The mushrooms soak up the wine-infused sauce, and every bite delivers that classic marsala depth.
Perfect for weeknight dinners or feeding a crowd. Here’s how to make it.
Ingredients for Chicken Marsala Casserole
Pantry staples and a few fresh ingredients create this hearty, comforting dish.
| Ingredient | Amount | Notes |
|---|---|---|
| Boneless, Skinless Chicken Breasts 🍗 | 1 ½ lb | Cut into bite-sized pieces |
| Cremini Mushrooms 🍄 | 1 lb | Sliced, stems removed |
| Marsala Wine 🍷 | 1 ½ cups | Dry variety preferred |
| Heavy Cream 🥛 | ¾ cup | Full-fat for richness |
| Chicken Broth 🥣 | 1 cup | Low-sodium preferred |
| All-Purpose Flour 🌾 | ¼ cup | For thickening sauce |
| Butter 🧈 | 2 tbsp | Unsalted, divided |
| Olive Oil 🫒 | 1 tbsp | For sautéing mushrooms |
| Yellow Onion 🧅 | 1 whole | Medium, finely diced |
| Garlic Cloves 🧄 | 3 cloves | Minced for depth of flavor |
| Dried Thyme 🌿 | ½ tsp | Or 1 tbsp fresh thyme |
| Kosher Salt 🧂 | 1 tsp | Plus more to taste |
| Black Pepper 🌶️ | ½ tsp | Freshly ground preferred |
| Parmesan Cheese 🧀 | ½ cup | Freshly grated for garnish |
| Fresh Parsley 🌿 | ¼ cup | Chopped, for finishing |
The chicken and mushrooms are the stars. Boneless, skinless breasts stay tender when cut into even pieces. I grab mine from Whole Foods or Costco—they’ve got the best quality for the price. Cremini mushrooms (those baby bellas) soak up the marsala sauce better than white button, but either works. Dry marsala wine is key for that classic depth—sweet marsala turns the sauce candy-like.
No marsala wine? Dry sherry or pinot grigio work in a pinch. Swap creminis for shiitake or oyster mushrooms if you’re feeling fancy. Heavy cream can be half-and-half (just thicken the sauce a bit longer). Fresh thyme is great if you’ve got it—use one-third the amount of dried. The Parmesan? Parmigiano-Reggiano if you’re splurging, but pre-grated works too.
Leftovers keep 4-5 days in the fridge, though the mushrooms get a little softer. Reheats like a dream—tastes even better the next day. Freezes for up to 3 months (thaw overnight before reheating).

Step-by-Step Instructions for Chicken Marsala Casserole
This one-dish wonder comes together beautifully with layers of rich, savory flavor.
Step 1: Sear the Chicken and Sauté the Aromatics
Heat 1 tbsp Olive Oil and 1 tbsp Butter in a large oven-safe skillet over medium-high heat until the butter melts and foams. Season the 1.5 lb Boneless, Skinless Chicken Breasts with 1 tsp Kosher Salt and 0.5 tsp Black Pepper, then add them to the pan.
Sear the chicken for 4-5 minutes per side until golden brown and cooked through. Remove and set aside. In the same pan, add the finely diced Yellow Onion and cook for 3 minutes until soft. Stir in the 3 cloves Garlic Cloves and 0.5 tsp Dried Thyme, cooking for 30 seconds until fragrant.
Step 2: Build the Marsala Sauce
Add the 1 lb Cremini Mushrooms to the skillet and cook for 6-8 minutes until they release their moisture and turn golden brown. Sprinkle the 0.25 cup All-Purpose Flour over the mushrooms and stir for 1 minute to create a light roux.
Pour in the 1.5 cups Marsala Wine and 1 cup Chicken Broth, scraping up any browned bits from the bottom of the pan. Bring to a simmer and cook for 5 minutes until the liquid reduces slightly. Stir in the 0.75 cup Heavy Cream and simmer for another 2-3 minutes until the sauce thickens.
Step 3: Assemble and Bake the Casserole
Return the seared chicken to the skillet, nestling the pieces into the sauce. Reduce the heat to medium and let everything simmer together for 5 minutes to meld the flavors.
Sprinkle the 0.5 cup Parmesan Cheese evenly over the top. Transfer the skillet to a preheated 375°F oven and bake for 15-20 minutes until the cheese is melted and bubbly, and the edges are lightly golden.
Step 4: Rest and Garnish Before Serving
Remove the casserole from the oven and let it rest for 5 minutes to allow the sauce to set slightly. This brief pause ensures the flavors deepen and the dish holds its shape when served.
Sprinkle with the 0.25 cup Fresh Parsley right before serving. Each portion should have tender chicken, rich sauce, and a golden cheese topping. Serve warm with crusty bread or over pasta to soak up every drop of the delicious Marsala sauce.
Pro Tips For Making Chicken Marsala Casserole
- Pound the Chicken: Slice the breasts horizontally then pound them to an even ½-inch thickness—I learned this the hard way after too many dry, chewy bites from uneven cooking.
- Brown the Mushrooms First: Cook the creminis in batches with a pinch of salt until deeply browned (about 5-6 minutes), or they’ll just steam and turn soggy in the casserole.
- Deglaze with Marsala: After browning the chicken, pour in ½ cup Marsala and scrape up all those browned bits—this is where the real flavor hides, and skipping it leaves the dish flat.
- Thicken Before Baking: Simmer the Marsala, broth, and cream on the stovetop for 3-4 minutes until slightly thickened, or your casserole will come out watery instead of rich and velvety.
Serving Suggestions for chicken marsala casserole
Plated Presentation
Serve this dish family-style straight from the skillet. The golden cheese topping looks stunning against the deep brown sauce. I love using my vintage cast iron for that rustic presentation that reminds me of home. 🔥
Starch Pairings
For soaking up that incredible sauce, crusty Italian bread is my go-to. Tear pieces off a fresh baguette for dipping. Alternatively, serve over fettuccine or pappardelle—the wide noodles capture the sauce beautifully.
Vegetable Sides
A simple arugula salad with lemon vinaigrette cuts through the richness. Toss 4 cups baby arugula with 2 tbsp olive oil and 1 tbsp lemon juice. Roasted asparagus or broccolini also complement the earthy mushrooms.
Garnish Ideas
Beyond the parsley, try topping with toasted pine nuts for crunch or shaved Parmesan for extra elegance. A drizzle of balsamic reduction adds a touch of sweetness that balances the marsala’s depth. 💫
Portion Tips
This serves 4 generously, but for a crowd, stretch it by serving with garlic mashed potatoes. The creamy potatoes pair perfectly with the wine-infused sauce. Leftovers reheat beautifully for lunch the next day.

Frequently Asked Questions
Can I use chicken thighs instead of breasts?
Yes! Boneless, skinless thighs work beautifully and stay even juicier. Reduce searing time to 3-4 minutes per side since dark meat cooks faster.
What if I don’t have marsala wine?
Substitute dry sherry or 1 cup chicken broth + 1/2 cup dry white wine. The flavor won’t be identical but still delicious. Avoid sweet wines.
Can I make this ahead?
Assemble the casserole (unbaked) up to 24 hours ahead. Refrigerate, then bake as directed, adding 5 minutes to the time.
Why is my sauce too thin?
Simmer uncovered for 2-3 extra minutes. If still thin, mix 1 tbsp cornstarch with 1 tbsp water and stir in. Let thicken before baking.
