Rotisserie chicken spaghetti bake layers shredded chicken, tender spaghetti, tomatoes, and melted cheese in a creamy sauce, then bakes until bubbly and golden for a family friendly casserole.
Store bought rotisserie chicken saves the hardest step, and everything mixes in one big bowl. Cover the dish for the first bake to keep it moist, then uncover it so the cheese on top turns brown.

Why This Rotisserie Chicken Spaghetti Bake Recipe Works
Using cooked rotisserie chicken cuts the prep time in half, and the meat stays tender because it only needs to heat through in the oven.
Slightly undercooked spaghetti finishes in the sauce, so the noodles absorb flavor and never turn soft or mushy after baking.
Cream of mushroom soup and cheese make a quick, creamy sauce, and diced tomatoes add brightness that cuts through the richness.
Ingredients for Rotisserie Chicken Spaghetti Bake
- For the filling: shredded rotisserie chicken, spaghetti cooked just shy of tender, a can of condensed cream of mushroom soup, and a can of drained diced tomatoes.
- For the topping: two cups of shredded cheese, half mixed into the casserole and half scattered on top, with optional leftover vegetables stirred in.
Rotisserie chicken. Remove the skin and bones, then shred the meat, mixing white and dark meat for juicy flavor.
Spaghetti. Boil the noodles for a minute less than the package says, since they keep cooking in the oven.
Cream of mushroom soup. This condensed soup works as the sauce base, and sour cream or Greek yogurt can replace it.
Diced tomatoes. Drain them well so the casserole does not turn watery, and choose plain tomatoes without added sugar.
Cheese. Cheddar, Monterey Jack, or a mix all melt well, and shredding a block yourself gives a smoother melt.
How to Make Rotisserie Chicken Spaghetti Bake
1. Heat the oven. Heat the oven to 350 degrees F and grease a large baking dish.
2. Boil the spaghetti. Cook the spaghetti until just shy of tender, then drain it and set it aside.
3. Mix the casserole. Combine the chicken, spaghetti, soup, drained tomatoes, and half of the cheese in a large bowl.
4. Add vegetables. Stir in any leftover cooked vegetables you want to use.
5. Cover and bake. Spread the mixture in the dish, sprinkle on the remaining cheese, cover with foil, and bake for thirty minutes.
6. Uncover and brown. Remove the foil and bake ten to fifteen minutes more, until bubbly and golden and the center reaches 165 F, then rest before serving.
How to Serve Rotisserie Chicken Spaghetti Bake
Let the casserole rest for ten minutes so the sauce thickens, then scoop it onto plates. It pairs well with an Italian house salad, air fryer garlic bread slices, air fryer asparagus, and roasted Brussels sprouts.
How to Store and Reheat Rotisserie Chicken Spaghetti Bake
Cool the casserole within two hours and refrigerate it in a covered dish for three to four days. Freeze portions in freezer safe containers for up to three months, thaw them overnight in the refrigerator, and bake covered until they reach 165 F.
Tips and Variations for Rotisserie Chicken Spaghetti Bake
Undercook the pasta. Pull the spaghetti while it still has a firm bite, so it does not turn soft in the oven.
Cover first. Foil keeps steam in during the first bake and prevents the top from drying out.
Add flavor. A pinch of garlic powder, onion powder, or black pepper boosts the sauce without extra effort.
Swap the soup. Cream of chicken soup works equally well, and sour cream makes a lighter, tangier sauce.
Flag the allergens. This casserole contains milk, wheat, and soy, and the soup may contain other allergens, so label it clearly.
Cool safely. Do not leave the casserole out for more than two hours, and divide leftovers into shallow containers.
Add crunch. A handful of buttery cracker crumbs on top before the last bake adds a golden crunch.
Check trusted guidance. Read the Purdue Extension guide to storing leftovers for safe chilling times.
