Easy Chicken Casserole with Stuffing

This chicken casserole with stuffing is the ultimate easy dinner. You put all the ingredients in a baking dish and in just 25 minutes you have chicken enveloped in a creamy sauce and crispy stuffing on top. I have been making this since my kids were small, and it still is a dish that everyone agrees on making because it’s so easy and everyone loves it.

The most valuable part is it can be prepared in advance. You can put it together the prior night or the morning of, wrap it, and put it in the fridge until it’s time to bake it. On nights where we’re busy with different obligations, having the meal in the refrigerator, all it needs is a little time in the oven, is what allows us to actually eat together. It’s that valuable.

Why This Bakes Up Just Right

• Cream of chicken soup does double duty — it acts as both the sauce and the moisture that keeps the chicken from drying out in a hot oven.
• The cheese goes under the soup, not on top, so it melts into the chicken instead of burning or getting rubbery.
• Crushed Stovetop stuffing tossed in butter gives you a topping that crisps up without going soggy — the contrast of creamy underneath and crunchy on top is what makes this dish.
• Thin tomato slices cut through the richness of the soup. Don’t skip them — they’re doing more than you’d think.
• It bakes at 400°F, which is hot enough to cook through in 25 minutes without turning the chicken dry and leathery.
• Assembly takes under 10 minutes — no sautéing, no pre-cooking the chicken, no complicated steps.

What to Know Before You Start

When it comes to chicken, size matters! In this recipe, we use skinless chicken breast halves, and assume they will bake for 25 minutes so they are not enormous 12-ounce breasts you might find at a supermarket. If your breasts are thick, either pound them out to an even thickness, or plan to check their temperature at 25 minutes. What you want at the thickest part is 165°F. Once chicken breast is overcooked, it becomes dry and no amount of sauce is going to save it.

If you’re making this ahead of time, take it out of the refrigerator about 20 minutes before putting it in the oven. An extremely cold meal that goes directly into an oven that’s hot could take longer to cook and might not cook evenly.

The stuffing layer must stay on top! When buttered stuffing crumbs are sprinkled over the tomatoes, do not press them into the sauce. It is going to be sitting on top to get crunchy if it sinks into the liquid it will steam instead of get brown.

Use a 3-quart oblong baking dish (about 9×13 inches). This gives the chicken enough room to lie flat in a single layer, which is important for even cooking and proper coverage of the topping.

Ingredients

• 4 skinless chicken breast halves — The base. Skinless keeps the topping from getting greasy. Boneless thighs work too and stay juicier, though the dish will be richer.
• 4 slices American or Swiss cheese — American melts smoothly and stays mild. Swiss gives a slightly sharper flavor. Use what you have — both work. This layer goes directly on the chicken.
• 1 can cream of chicken soup — Stir it with milk first so it spreads evenly rather than sitting in thick clumps on top of the cheese.
• ½ cup milk — Thins the soup enough to make it spreadable and keeps the sauce from getting gluey as it bakes.
• 4 thin tomato slices — Slice them thin so they soften fully. Thick slices stay too firm and add too much moisture to the top layer.
• 2 tablespoons melted butter — Coats the stuffing so it browns and crisps. Dry stuffing on top just stays dry.
• 1 cup Stovetop stuffing, crushed — Crushing gives you finer crumbs that spread more evenly and crisp up better than whole cubes. A quick crush in a zip-lock bag takes 30 seconds.
• Hot cooked rice, for serving — The sauce from the casserole is generous and soaks into the rice. White rice is the classic pairing; brown rice works too.

How to Make It

Step 1: Preheat and prep

To start, preheat the oven to 400°F. Then, lightly grease a 3-quart oblong baking dish with a quick spray of cooking spray. This will prevent the chicken from sticking and will make cleaning up a little easier!

Step 2: Layer the chicken

Lay the chicken breast halves in the dish one layer thick. They can be close together but not overlapping. If the pieces are not the same thickness, follow under the thinner ends a little so they do not overcook before the thicker ones are ready.

Step 3: Add the cheese

Put one slice of cheese on each chicken breast so that it covers most of the chicken. As the cheese melts, it will create a barrier between the chicken and the sauce on top.

Step 4: Mix and spread the soup

In a separate bowl combine the cream of chicken soup and milk and mix until smooth. Pour the mixture over the cheese layer and spread it so it covers all the chicken. Keep in mind that if the soup is cold from the fridge, it will be stiffer than expected. So stir it a bit before spreading.

Step 5: Add tomato slices

About one slice of tomato per chicken breast goes on top of the soup layer. While baking, the tomatoes soften and release their juice. This keeps the top from drying out and adds faint acidity to balance the richness of the layers below.

Step 6: Make the stuffing topping

In a bowl or zip-lock bag, crush the Stovetop stuffing so the cubes become smaller crumbs. Combine with the melted butter so that all the crumbs are covered. Sprinkle evenly over the tomatoes. Do not press it down, so it sits lightly on top. This will help it crisp in the oven.

Step 7: Bake

Bake in the oven at 400°F for 25 minutes, or until the chicken is done and the stuffing topping is nicely browned. At 25 mins, check the thickest part of the chicken with a meat thermometer. It should read 165°F. Do not cover the dish or else the stuffing topping will steam instead of crisping up.

Step 8: Rest and serve

Once it comes out of the oven, allow the casserole to rest for 3 to 4 minutes. Serve on top of hot, cooked rice — the sauce is abundant and seeps in wonderfully.

Helpful Tips

Use a meat thermometer

There is no way to know the correct cooking time for chicken just by looking at the chicken, which makes the cooking time more of a guess than anything. Using an instant-read thermometer will let you know exactly when the chicken is safe to eat and will save it from being overcooked. As soon as the thickest chicken breast reads at least 165°F, take the casserole out. This will ensure that the chicken is never dry in your chicken casserole!

Crush the stuffing first

Whole stuffing cubes on top can brown unevenly and harden in some places. Crushing them improves the topping because it creates more even coverage across the entire dish.

A note on cream of mushroom

In a pinch, it’ll work, but the flavor changes quite a bit — it’s a more earthy, darker sauce. If that is all you have, it still makes dinner. But cream of chicken keeps the sauce flavor mild, letting the stuffing topping stay front and center.

Shortcut with rotisserie chicken

If you have cooked or leftover chicken to use, you can use shredded chicken instead of raw chicken breasts. Your bake time will only be ~15 minutes since the only thing you have to do is heat everything. This is perfect for when you have a really tight schedule.

Variations

Add vegetables

Before adding cheese, scatter frozen green beans or peas around the chicken. Since they are pre-cooked, they will be done by the end of the 25-minute bake time, and the dish will have veggies without any extra prep!

Swap the cheese

Provolone cheese melts easily and tastes a little more savory than American cheese, and Mozzarella, while still good, is even milder than American Cheese. When melted Cheddar cheese can get oily at the bottom of the soup, so use it sparingly if at all.

Use chicken thighs

Boneless skinless chicken thighs are easier to cook than breasts since they stay juicier and are less likely to be overcooked. The baking time is comparable, likely only 5 minutes longer. Many people find the taste to be better.

Storage, Make-Ahead, and Leftovers

Make-ahead: Assemble everything up until the stuffing topping, cover it, and store it in the fridge for up to 24 hours. Before baking, take it out 20 minutes. If it’s still cold in the middle, you may need an additional 5 minutes in the oven.

Leftovers: Store covered in the fridge for up to 3 days. The stuffing topping will soften overnight, which is normal for a casserole. It still tastes just as good, just not crispy.

Reheating: To reheat single servings, use the microwave on medium power with the dish cover loosely. To reheat the entire meal, use the oven at 350°F for approximately 15 minutes with the foil on top. If you want the topping to be re-crisped, take off the foil 5 minutes before the heating is complete.

Once assembled, this casserole can be frozen. Just cover the dish tightly and put it in the freezer. To bake, thaw in the fridge overnight first. If you want the best topping texture, bake it after thawing, rather than freeze then bake.

Frequently Asked Questions

Can I use frozen chicken breasts?

First, thaw them. If you bake frozen chicken in a casserole the outside will overcook before the inside is at a safe temperature, plus frozen chicken will release extra water which will make the sauce way too thin. You can thaw in the fridge overnight, or if you’re short on time, use the cold water method.

Does the chicken need to be browned first?

No, that’s part of what makes this recipe really quick. You put raw chicken into the dish, and it gets cooked in the 400°F oven in 25 minutes. You won’t get a sear on the outside because it gets buried under sauce and cheese, but the texture is completely fine — it is moist and cooked all the way through without any pre-work.

What if I do not have Stovetop stuffing?

Use any dry stuffing mix, like store brand, cornbread, or herb. Crush it prior to using so that the pieces crisp up uniformly. If you have an absence of stuffing mix, seasoned breadcrumbs serve as a substitute. Use around ¾ cup and mix it with the melted butter.

Can I double this recipe?

Of course! Use two baking pans. Don’t try to squeeze in double the chicken into one pan — it will cook unevenly and the topping will not cover evenly. Bake time remains about the same; just check the internal temp on the thickest piece.

The sauce looks thin when it comes out of the oven — is that normal?

Yes, as it bakes, it will loosen up, and it will thicken a bit as the dish cools. The 3–4 minutes resting after baking will help. For a thicker sauce you could start with ⅓ cup milk instead of ½.

What else can I serve this with besides rice?

You can be a bit carefree with your choice of side dishes. All of them offer a different approach to how the sauce interacts with the dish. What are your thoughts on egg noodles? Since the sauce will coat them the same way that it will do to the rice, it will fit in nicely. What about mashed potatoes? The sauce will work like gravy, so it will work out again. To keep it simple, a side salad also works, and roasted broccoli will also be great without too much effort to round off the meal.
