Ingredients You’ll Need

The beauty of Creamy Onion Chicken Bake with Stuffing is how a few simple ingredients come together to create pure magic. Each one brings its own special something—flavor, creaminess, crunch, or a touch of color—and together, they transform into a dish everyone will crave.

Chicken Breasts: Use boneless, skinless breasts for tender, juicy results and a fuss-free presentation.
Stuffing Mix: This shortcut brings irresistible herbiness and texture; choose your favorite brand for nostalgia or quality.
Hot Water: Hydrates and fluffs the stuffing for a perfectly soft (yet golden) topping.
Cream of Onion Soup: The flavor foundation—creamy, savory, and full of gentle onion sweetness.
Sour Cream: Lends tang and extra silkiness to the sauce, keeping the bake moist and decadent.
Milk: Balances out the soup and sour cream, creating a pourable sauce that coats the chicken.
Garlic Powder: Just a half teaspoon, but it deepens and rounds out the flavor beautifully.
Onion Powder: Doubles down on that sweet onion flavor for an even more savory bite.
Black Pepper: Adds a gentle kick and warms up all the creamy elements.
Shredded Mozzarella Cheese: For that gooey, melty finish—try a little extra if you love cheese pulls!
Unsalted Butter: Melted into the stuffing for a buttery, bakery-style crispness on top.
Fresh Parsley (optional): Just a sprinkle before serving, for a pop of color and garden-fresh flavor.

How to Make Creamy Onion Chicken Bake with Stuffing

Step 1: Prep and Preheat

Start by preheating your oven to 375°F (190°C) so it’s ready when you are. Take a 9×13-inch baking dish and lightly grease it—this keeps the chicken extra juicy and ensures easy cleanup. Having everything ready at hand makes assembling your Creamy Onion Chicken Bake with Stuffing completely stress-free.

Step 2: Mix Up the Stuffing

Grab a medium bowl and combine the stuffing mix with the hot water and your melted butter. Stir until just moistened—don’t overmix so you keep those lovely stuffing crumbles that toast up perfectly in the oven. Set this aside while you move on to the creamy sauce.

Step 3: Whisk Up the Creamy Onion Sauce

In a separate bowl, whisk together the cream of onion soup, sour cream, milk, garlic powder, onion powder, and black pepper. This luscious blend will blanket your chicken breasts, keeping them succulent and infusing them with sweet, savory, herby flavors that make this dish irresistible.

Step 4: Assemble in Layers

Arrange the chicken breasts in your greased baking dish. Pour the creamy onion mixture over the chicken, spreading it evenly so every bite gets that luscious sauce. Next, gently spoon the moistened stuffing over everything, creating a crumbly layer that will bake up golden and crisp. Sprinkle the shredded mozzarella evenly to finish off the prep like a pro.

Step 5: Bake to Golden Perfection

Cover the dish tightly with foil and bake for 25 minutes. This steams the chicken and infuses the flavors. Then, remove the foil and bake for another 10 to 15 minutes. Keep an eye out for the stuffing and cheese turning temptingly golden and make sure the chicken is fully cooked (it should reach 165°F inside). A final sprinkle of chopped fresh parsley right before serving gives everything a restaurant-worthy finish.

How to Serve Creamy Onion Chicken Bake with Stuffing

Garnishes

Nothing says “fresh and finished” quite like a sprinkle of bright green parsley—but you can get creative! Try a touch of cracked black pepper, some thinly sliced green onions, or even a scatter of crispy fried onions for crunch. The contrasts in color and texture not only make your Creamy Onion Chicken Bake with Stuffing look stunning but bring out the flavors too.

Side Dishes

This cozy bake is practically a meal in itself, but serving it alongside crisp-tender green beans or a simple garden salad adds freshness and vibrance. Steamed broccoli, glazed carrots, or even roasted Brussels sprouts would all pair beautifully and balance out the creamy richness of the main dish.

Creative Ways to Present

You can dress things up by serving the Creamy Onion Chicken Bake with Stuffing in individual ramekins or mini casseroles for a dinner party-worthy twist. For a weeknight family meal, scoop generous servings straight from the pan—rustic and inviting. If you’re making it for a potluck, bring the entire bake, sprinkle herbs right before serving, and watch it disappear in moments.

Make Ahead and Storage

Storing Leftovers

Once cooled, transfer any leftover Creamy Onion Chicken Bake with Stuffing to an airtight container and refrigerate for up to 3 days. The flavors continue to meld, making leftovers arguably even more delicious for a next-day lunch or dinner. Just be sure to store the stuffing on top so it maintains some of its delectable texture.

Freezing

If you want to make this dish ahead of time, simply assemble (but don’t bake) the casserole in a freezer-safe dish. Cover tightly with both plastic wrap and foil, and freeze for up to 2 months. When you’re ready to enjoy it, thaw overnight in the fridge and bake as directed, adding an extra 10–15 minutes if needed to ensure it’s heated through.

Reheating

To reheat, place individual portions or the whole dish (covered with foil) in a 350°F oven until hot and bubbling—usually about 20 minutes for a casserole and around 5 minutes for single servings. For small portions, a quick microwave zap works too, but the oven keeps the stuffing top its crispiest best.

FAQs

Can I use chicken thighs instead of breasts?

Absolutely! Boneless, skinless chicken thighs will be just as tasty and perhaps even juicier. Simply arrange them in the dish as you would the breasts—just check they’re cooked through, as thighs may require a few extra minutes in the oven.

What if I can’t find cream of onion soup?

No worries at all. You can swap in cream of chicken or cream of mushroom soup with great results—they’ll each bring a slightly different flavor twist that still tastes fantastic in your Creamy Onion Chicken Bake with Stuffing.

Can I add vegetables to make it a complete meal?

Yes! Feel free to add in some cooked and drained spinach, thinly sliced bell peppers, or sautéed onions and celery between the chicken and stuffing layers. Just be cautious not to overload the pan or the bake may become watery.

Is it possible to assemble this casserole ahead of time?

Definitely. You can fully assemble the Creamy Onion Chicken Bake with Stuffing up to 24 hours in advance, cover tightly, and refrigerate. This can even deepen the flavor as everything melds together—just bake as written when you’re ready to serve.

Can I make this dish gluten-free?

Yes you can! Use a gluten-free stuffing mix and check that your soup and other ingredients are certified gluten-free. The results are just as creamy, satisfying, and full of flavor.

Final Thoughts

If you’re ready for a casserole that’s big on comfort and even bigger on flavor, give Creamy Onion Chicken Bake with Stuffing a spot on your menu. It’s endlessly adaptable, simple to make, and guaranteed to win fans every time it hits the table. Go ahead—treat yourself and your loved ones to this deliciously creamy, crowd-pleasing favorite!
