Creamy One-Dish Chicken Marsala Casserole

This Chicken Marsala Casserole takes the classic Italian‑American dish and turns it into a cozy one‑dish dinner. Tender chicken, earthy mushrooms, and a creamy marsala sauce bake up with pasta so everything melds together.

It feels a little special, like a Sunday supper, yet it comes together without a pile of pots and pans. The oven does the heavy lifting while you put together a simple salad.

Why This Casserole Works

White grape juice gives the sauce a rich, slightly sweet depth that tastes like it simmered for hours. The mushrooms soak up that flavor, and the chicken stays juicy even after baking.

Baking everything in one dish means less cleanup and more time for the sauce to really get into every bite. The top turns just golden and bubbly, and the kitchen smells incredible.

Ingredients

• 1 lb boneless, skinless chicken thighs: cut into bite‑sized pieces; breasts work too but thighs stay more tender.
• 1 lb penne pasta: or any short shape like rigatoni.
• 2 tbsp olive oil: for browning the chicken.
• 2 tbsp unsalted butter: for the mushroom base.
• 1 medium yellow onion: diced.
• 3 cloves garlic: minced.
• 8 oz cremini mushrooms: sliced; white button mushrooms are fine in a pinch.
• 3 tbsp all‑purpose flour: thickens the sauce without making it heavy.
• 1 cup white grape juice: sweet or dry; sweet gives a deeper caramel note.
• 1 cup low‑sodium chicken broth: keeps the sauce savory, not salty.
• ½ cup heavy cream: makes the sauce luscious.
• ¾ cup grated parmesan: half into the sauce, half on top.
• Salt and black pepper: to season as you go.
• Fresh parsley: chopped, for a bright finish.

Variations / Substitutions

• Use leftover rotisserie chicken: shred about 3 cups and skip the searing step; the casserole will come together even faster.
• Different mushrooms: shiitake or oyster mushrooms add a woodsy note; just slice them thin.
• Dairy‑free: swap heavy cream for full‑fat coconut milk and use a plant‑based parmesan. The sauce will be a touch lighter.

How to Make Chicken Marsala Casserole

Step 1: Cook the Pasta

Bring a large pot of salted water to a rolling boil and cook the 1 lb penne until just al dente, about 8 minutes. Drain well and set aside while you work on the rest.

The pasta will finish cooking in the oven later, so keeping it a little firm now prevents it from turning mushy in the sauce.

Step 2: Sear the Chicken

Season the 1 lb of chicken thigh pieces with a generous pinch of salt and a few grinds of pepper. Warm the 2 tbsp olive oil in a large ovenproof skillet over medium‑high heat. Add the chicken in a single layer and cook until deep golden on one side, about 5 minutes, then give it a stir and cook 2 minutes more. Transfer the chicken to a plate; it does not need to be cooked through.

That golden crust on the chicken builds a flavor base for the whole dish, so don’t rush this step.

Step 3: Sauté the Mushrooms

Drop the heat to medium and melt the 2 tbsp butter in the same skillet. Add the 1 diced onion and the 8 oz sliced mushrooms. Cook, stirring now and then, until the mushrooms soften, release their liquid, and start to brown, about 6 minutes. Stir in the 3 minced garlic cloves and cook until fragrant, 1 minute.

Watch for the moment the mushrooms stop steaming and begin to sizzle in the butter. That’s when you know they’re ready for the next step.

Step 4: Build the Sauce

Sprinkle the 3 tbsp flour over the mushroom mixture and stir constantly for 1 minute to cook out the raw flour taste. Slowly pour in the 1 cup white grape juice and the 1 cup chicken broth, whisking to dissolve any floury bits. Bring the sauce to a gentle simmer and let it thicken, about 3 minutes. Stir in the ½ cup heavy cream and ½ cup of the grated parmesan. Taste and season with a little more salt and pepper.

The sauce should nicely coat the back of a spoon. If it seems too thick, add a splash of broth; too thin, let it bubble another minute.

Step 5: Assemble and Bake

Preheat your oven to 375°F (190°C) if you haven’t already. Add the drained pasta and the seared chicken (along with any juices on the plate) back into the skillet. Toss gently until every piece is coated. Sprinkle the remaining ¼ cup parmesan over the top. Bake for 25 to 30 minutes, until the casserole is bubbly around the edges and the top has a golden, slightly crusty look.

The sauce will look a bit loose when you first pull it out of the oven, but it settles and thickens as the casserole sits for a few minutes.

Step 6: Finish and Serve

Let the casserole rest on the stovetop for 5 minutes, then scatter a handful of chopped fresh parsley over the top. Carry the skillet straight to the table and scoop generous portions onto plates.

That pop of green from the parsley wakes up the whole dish, and the short rest makes the sauce cling perfectly to every bite.

Tips for the Best Chicken Marsala Casserole

• A heavy, ovenproof skillet (cast iron or stainless steel) gives you great browning and goes right into the oven. If you don’t have one, sear in a regular pan and transfer everything to a greased 9×13 baking dish.
• Don’t skip the chicken sear. That browned layer on the skillet bottom, which you later deglaze with the juice, is the foundation of the sauce’s deep flavor.
• Use a marsala you’d drink—sweet provides a wonderful caramelized quality, dry is a bit more savory. Avoid “cooking juice” which has added salt and can throw off the seasoning.
• Taste the sauce before assembling. The parmesan and broth already contribute salt, so go easy on extra salt until you’ve sampled it.

Bake times by dish size: a shallower dish bakes faster and gets a crispier top.

Storing Leftovers

Cover and refrigerate any cooled leftovers for up to 4 days. The casserole reheats beautifully in a 350°F oven until warmed through, or in the microwave for a quicker lunch. The pasta will absorb some sauce as it sits; if it feels dry, stir in a splash of broth or cream before reheating.

What to Serve With Chicken Marsala Casserole

A simple arugula salad with a squeeze of lemon and shaved parmesan cuts through the creaminess and adds a fresh, peppery note. Garlic bread or warm ciabatta is perfect for swiping up every last bit of sauce on the plate. For a veggie side, roasted asparagus or green beans tossed with olive oil and salt cook quickly while the casserole bakes.

Frequently Asked Questions

Can I use chicken breasts instead of thighs?

Yes, you can. Cut them into similar sized pieces, but watch the cooking time carefully because breasts dry out faster than thighs; 3 minutes on the first side for the sear is usually enough.

Can I assemble this casserole ahead of time?

Absolutely. Follow the recipe through Step 5 (without baking), cover tightly, and refrigerate for up to 24 hours. Let it sit at room temperature while the oven preheats, then bake as directed, adding 5 to 10 minutes.

Can I freeze it?

You can. Assemble the unbaked casserole, wrap it well, and freeze for up to 2 months. Thaw overnight in the fridge before baking, or bake straight from frozen at 350°F, covered, for about 50 minutes, then uncover for the final 15.

What other pasta shapes work well?

Any short, sturdy shape like rigatoni, fusilli, or ziti holds the sauce nicely. Long noodles like spaghetti aren’t great here because they clump together in the skillet.

Notes

Let the casserole rest for a few minutes after baking so the sauce sets and clings to the pasta. For a nuttier flavor, lightly toast the parmesan‑topped casserole under the broiler for the final 2 minutes—watch it closely.
