Leftover Smoked Chicken and Broccoli Casserole
A golden layer of cheddar and breadcrumbs covers smoky chicken, tender broccoli, and a creamy mushroom filling. This casserole recipe using leftover smoked chicken brings those flavors together with a little honey mustard and paprika. The result is a cozy dinner with a savory, smoky bite beneath every spoonful of sauce.
Why This Recipe Works
Smoked chicken has a bold flavor that can easily get lost under a heavy sauce. Here, the mushroom mixture stays mild enough to let that smoky taste come through. Honey mustard adds a gentle tang that cuts through the rich cheddar, while broccoli breaks up the creamy filling. The breadcrumb topping adds a little crunch, giving each serving more character than a bowl of soft, cheesy ingredients.

What You’ll Need
| Ingredient | Amount |
|---|---|
| Leftover smoked chicken, chopped | 1 lb (about 3 cups) |
| Broccoli florets, lightly steamed | 1½ cups |
| Milk | ½ cup |
| Sharp cheddar cheese, shredded | 1½ cups |
| Condensed cream of mushroom soup | 1 can (10.5 oz) |
| Plain Greek yogurt | ⅔ cup |
| Honey mustard | 1 tablespoon |
| Everyday seasoning | ½ tablespoon |
| Paprika | ½ teaspoon |
| Plain breadcrumbs | ¼ cup |
Choose smoked chicken with a flavor you enjoy, since its seasoning will carry through the entire casserole. Remove any bones, then chop the meat into bite-sized pieces. Pieces around ¾ inch work well because they stay noticeable among the broccoli florets.
For the broccoli, aim for florets that are bright green and still a little firm. They will soften further in the oven. Very soft broccoli can break apart when you stir it into the thick mushroom sauce.
Sharp cheddar is worth using here. Its stronger flavor stands up to the smoked chicken, so the cheese tastes distinct rather than disappearing into the filling. Shred it yourself if possible, especially if you want a smooth, even melt.
The everyday seasoning can be your usual all-purpose blend. However, check how salty your smoked chicken tastes before adding the full amount. Both the chicken and condensed soup may bring plenty of salt.
Reheating Tip
For this casserole, warm the chopped leftover smoked chicken gently in a covered nonstick skillet before mixing it with the sauce. Add 1–2 tablespoons of the measured milk and heat over medium-low for about 2–3 minutes, stirring occasionally. The goal is to loosen the chilled pieces and warm them slightly, not to brown their edges.
A nonstick skillet with a lid works well because the covered pan traps a little steam around the chicken. This helps protect the exposed meat while keeping the smoky surface from drying out. Transfer the chicken and any liquid directly into the casserole mixture. The oven will finish heating everything together.
How to Refresh the Smoky Flavor
The trick with leftover smoked chicken is knowing when to leave its flavor alone. Too much seasoning can hide the very taste that makes this casserole interesting.
Whisk the honey mustard and paprika thoroughly into the creamy mushroom mixture before adding the chicken. That small amount of tang gives the smoked meat a brighter finish without turning the casserole into a mustard dish.
A small mixing bowl and whisk help distribute the honey mustard evenly. Otherwise, you may end up with one sharp-tasting pocket of sauce and another that tastes mostly of mushroom soup. Once mixed, fold the chicken through gently so every piece gets a light coating.
How to Make Leftover Smoked Chicken and Broccoli Casserole
Step 1: Prepare the Chicken and Broccoli
Preheat your oven to 400°F. Lightly grease an 8 × 8-inch baking dish.
Remove any bones from the leftover smoked chicken and cut the meat into bite-sized pieces. If the chicken has thick, chewy skin, remove it for a smoother casserole filling.
Steam the broccoli until bright green but still firm. Drain it well, then set it aside. Excess water can thin the sauce once the casserole starts bubbling.
Step 2: Warm the Smoked Chicken
Place the chopped chicken in a nonstick skillet with a lid. Add 1–2 tablespoons of the measured milk.
Cover and warm over medium-low heat for about 2–3 minutes, stirring once or twice. Keep the heat gentle and stop when the pieces have softened and begun to warm.
Transfer the chicken and any remaining liquid to a large mixing bowl.
Step 3: Mix the Creamy Sauce
In a separate bowl, whisk together the condensed cream of mushroom soup, remaining milk, Greek yogurt, and honey mustard.
Add 1 cup of shredded sharp cheddar, the everyday seasoning, and paprika. Stir until the cheese and seasonings are evenly distributed.
The mixture should look thick and creamy. It will loosen as it heats in the oven, so avoid adding extra milk unless it is unusually stiff.
Step 4: Combine the Chicken and Broccoli
Add the sauce to the bowl of warmed smoked chicken. Fold gently until the pieces are coated.
Next, add the steamed broccoli. Use a spatula to turn the mixture a few times, keeping the florets as intact as possible.
You should see distinct pieces of smoked chicken and broccoli throughout the filling, with enough sauce to hold everything together.
Step 5: Assemble the Casserole
Spoon the mixture into your prepared 8 × 8-inch baking dish. Spread it into an even layer, pushing the filling gently toward the corners.
Scatter the remaining ½ cup of shredded cheddar across the surface. Then sprinkle the breadcrumbs evenly over the cheese.
Keep the breadcrumb layer light. You want a little golden crunch without creating a thick, dry crust.
Step 6: Bake Until Golden and Bubbling
Place the dish on the middle oven rack and bake at 400°F for approximately 20–30 minutes.
Look for bubbling sauce around the edges, melted cheddar, and a lightly golden breadcrumb topping. The center should reach 165°F when checked with an instant-read thermometer.
If the breadcrumbs brown before the center is hot, loosely cover the dish with foil and continue baking.
Step 7: Rest and Serve
Remove the casserole from the oven and let it rest for about 5 minutes.
During that time, the creamy filling will settle slightly, making it easier to scoop without spreading across the plate.
Serve generous portions on their own or spoon them over warm rice or mashed potatoes. The mild base pairs nicely with the smoky chicken and cheddar sauce.
Conclusion
That first spoonful should have a little of everything: smoky chicken, soft broccoli, creamy mushroom sauce, and golden crumbs. The sharp cheddar brings it all together without stealing the show. This casserole recipe using leftover smoked chicken makes a satisfying dinner, especially when served straight from the warm baking dish with a spoonful of that bubbling sauce.
