Ingredients Needed to Make Easy Leftover Chicken Casserole with Stuffing
- 4 tbsp butter
- 1 small onion, diced
- 3 celery sticks, diced
- 2 garlic cloves, minced
- 1 tsp dried thyme
- 1 tsp dried rosemary
- 1 tsp salt
- 1/4 tsp ground nutmeg
- 1 tsp ground pepper
- 4 tbsp all-purpose flour
- 1 tbsp grainy mustard
- 1 1/2 tbsp chicken stock paste (like Better Than Bouillon)
- 1 tsp garlic base
- 2 cups water
- 2 cups whole milk
- 1 cup leftover cooked carrots, diced
- 1 cup leftover assorted vegetables (beans, brussels sprouts, or peas)
- 4 cups cooked shredded chicken
- 4-5 cups leftover cooked stuffing
Instructions to Make Easy Leftover Chicken Casserole with Stuffing – Step by Step
Step 1: Get your oven preheated to 375F and take a moment to grease your 9×13 baking dish thoroughly so nothing sticks. This ensures that the edges get nice and crispy without making a mess that you have to scrub later.
Step 2: In a large high-sided skillet or pot, melt your butter over medium-high heat. Once it is bubbling, turn the heat down to medium and toss in your diced onion and celery, along with any raw veggies you might be using. Let those veggies sauté for about 6-8 minutes until they are softened and just starting to show a little golden brown hue.
Step 3: Sprinkle in the minced garlic, thyme, rosemary, salt, nutmeg, and pepper. Stir these aromatic spices into the vegetable mix for about 1-2 minutes until your kitchen smells like a dream.
Step 4: Stir in the flour to coat the vegetables and cook it for a minute to remove the raw flour taste. Add in your bouillon bases, mustard, and slowly pour in the water and whole milk while whisking constantly. You want a smooth, silky gravy that will coat the chicken perfectly.
Step 5: Increase the heat to high to bring the gravy to a boil, then immediately drop it to a simmer. Let it bubble gently for 6-10 minutes, stirring often, until it thickens into a rich, velvety consistency.
Step 6: turn off the heat, stir in your leftover carrots, other cooked vegetables, and the shredded chicken into the gravy. Pour the entire mixture into your prepared baking dish.
Step 7: Take your pre-cooked stuffing and scatter it in generous dollops over the top of the chicken mixture. Don’t worry about it being perfectly level, as those little peaks will get an extra crunch in the oven.
Step 8: Pop your masterpiece into the oven for 25-30 minutes. You are looking for the gravy to be bubbling at the edges and the stuffing to have a deep, golden brown color. Let it rest for 5-10 minutes before serving so the liquid can settle slightly.
Chef’s Tips for a Perfect Result
- Always let the casserole rest for at least 10 minutes to allow the sauce to set perfectly.
- If your stuffing feels a little dry, pulse it with a tiny splash of chicken stock before topping the dish.
- Use room temperature milk and water to ensure you get a lump-free gravy every single time.
- Keep the stuffing topping light and airy rather than packed down to achieve that coveted crispy texture.
- Use a mix of different colored vegetables to make the dish pop visually on the dinner table.
Variations and Substitutions
Gluten-Free Alternative: Swap the all-purpose flour for a 1:1 gluten-free baking flour blend and ensure your stuffing is made with gluten-free bread crumbs.
Vegetarian Version: Replace the chicken with cooked chickpeas or pan-fried mushrooms, and use a high-quality vegetable bouillon base instead of the chicken stock paste.
Low-Carb Version: Replace the stuffing topping with a mixture of almond flour, grated parmesan cheese, and melted butter to mimic that crispy, savory topping.
How to Serve and Pair
This dish is incredibly hearty, so keep your side dishes light and refreshing. A simple green salad with a sharp balsamic vinaigrette cuts through the richness beautifully. Serving this alongside some steamed long-stem broccoli or roasted asparagus adds a vibrant pop of color and a fresh snap of texture. For a family dinner, it is perfect on its own, perhaps with a side of warm dinner rolls if you have extra appetites at the table.
Storage and Reheating
Refrigerator
Store any leftovers in an airtight container for up to 3 days. The flavors actually tend to meld even better the next day, making it a fantastic lunch option.
Freezer
You can freeze the casserole before or after baking for up to 2 months. Make sure to double-wrap the dish tightly with plastic wrap and foil to prevent freezer burn.
Reheating
When reheating, use a moderate oven at 350F until heated through. If it seems a little dry, add a splash of chicken broth before it goes into the oven to bring that velvety moisture back to the filling.

Frequently Asked Questions (FAQ)
Can I make this with store-bought stuffing?
You absolutely can use store-bought boxed stuffing to make this recipe easier. Just prepare the stuffing according to the box instructions before dolloping it over the chicken mixture.
How do I know when the casserole is fully heated?
The casserole is finished when the gravy is visibly bubbling up around the edges and the top stuffing layer is golden brown and crispy to the touch.
Why is my sauce too thin?
If the sauce seems too thin, make sure you let it simmer long enough to thicken before adding the chicken. If it is already in the oven, simply cook it for an extra 10 minutes under the broiler for the last few moments.
Can I assemble this earlier in the day?
You can definitely assemble the casserole in the morning and keep it in the fridge until you are ready to bake. If baking from cold, add about 10 minutes of extra time to ensure it is hot all the way through.
How can I make this flavor more robust?
Adding a splash of fresh lemon juice or even a teaspoon of Dijon mustard at the very end can brighten up the flavors and add a complex acidity to the savory chicken.
