Rotisserie chicken casserole is one of those dishes that saves busy weeknights without sacrificing an ounce of comfort.

There’s something magical about watching a simple casserole come together in your kitchen. Betty learned this recipe during those hectic years of raising three children, when time was precious but family dinners were non-negotiable. She’d pick up a rotisserie chicken from the market on her way home, and within an hour, the house would fill with the aroma of bubbling cheese and buttery crackers turning golden in the oven. The kids would gather around the table, and even on the busiest days, that casserole made everything feel right. It became her go-to whenever life got overwhelming—a one-dish wonder that delivered both convenience and that soul-warming comfort only home cooking can provide. Time to get our hands floury.

Ingredient Spotlight
Rotisserie Chicken: The star of this dish saves you at least 45 minutes of cooking time while delivering perfectly seasoned, juicy meat. I always choose a chicken that’s still warm from the store for the easiest shredding and best flavor. Both white and dark meat work beautifully, though Betty prefers using a mix for the most flavor.
Egg Noodles: These wide, tender noodles soak up the creamy sauce beautifully and provide that classic casserole texture. Betty prefers egg noodles because they hold up well during baking without turning mushy.
Cream of Chicken Soup: This pantry staple creates the rich, velvety base that holds everything together. In my kitchen, I use the full-sodium version because it provides better flavor depth, but low-sodium works if you’re watching salt intake.
Sour Cream: Adding sour cream gives the sauce a wonderful tangy richness that balances the creaminess and prevents the dish from tasting one-dimensional.
Cheddar Cheese: Sharp cheddar is Betty’s preference because it adds bold flavor that stands up to the other ingredients. We divide it one cup melted into the mixture and half a cup sprinkled on top for that gooey, golden finish.
Butter Crackers: Crushed Ritz crackers tossed with melted butter create that signature crunchy topping everyone fights over. I’ve learned that crushing them by hand in a plastic bag gives you the perfect texture not too fine, not too coarse.
Frozen Peas and Carrots: These convenient vegetables add color, nutrition, and little pops of sweetness throughout the casserole. Betty always thaws them first to prevent excess moisture from making the sauce watery.
Garlic and Onion Powder: These simple seasonings provide aromatic depth without the need for chopping fresh aromatics. After years of making this, I’ve found that this combination gives consistent flavor in every bite.
How to Make Rotisserie Chicken Casserole
Step 1. Preheat your oven to 350°F and grease a 9×13-inch baking dish with butter or nonstick spray. Betty always uses butter because it adds flavor and prevents any sticking along the edges.
Step 2. Bring a large pot of salted water to a rolling boil and cook the egg noodles for 6-7 minutes until al dente they should still have a slight bite when you test one. I’ve learned that undercooking them slightly is crucial since they’ll continue softening in the oven.
Step 3. While the noodles cook, whisk together the cream of chicken soup, sour cream, and milk in a large mixing bowl until completely smooth with no lumps. Add the garlic powder, onion powder, salt, and pepper, then taste and adjust the seasoning to your preference.
Step 4. Drain the noodles well and add them to the sauce along with the shredded rotisserie chicken and thawed peas and carrots. Betty’s tip: Stir gently but thoroughly so every noodle gets coated in that creamy goodness.
Step 5. Fold in 1 cup of the shredded cheddar cheese, reserving the remaining half cup for topping. Through trial and error, I learned that mixing most of the cheese into the filling creates pockets of melted cheese throughout.
Step 6. Transfer the mixture to your prepared baking dish and spread it into an even layer, then sprinkle the reserved cheddar cheese over the top for that irresistible golden finish.
Step 7. In a small bowl, toss the crushed butter crackers with melted butter until every crumb is coated, then scatter this mixture evenly over the cheese layer. The key I discovered is making sure the topping covers the entire surface for maximum crunch.
Step 8. Bake uncovered for 30-35 minutes until the rotisserie chicken casserole is bubbling vigorously around the edges and the cracker topping turns deep golden brown. If the top browns too quickly, tent it loosely with foil, then let it rest for 5-10 minutes before serving so the sauce thickens perfectly.
Keeping This Rotisserie Chicken Casserole Fresh
I typically store leftovers in an airtight container in the refrigerator for up to 3-4 days, and honestly, this casserole is one of those magical dishes that tastes even better the next day as the flavors meld together. Betty always portions out individual servings in smaller containers for easy grab-and-go lunches throughout the week.
If you want to freeze this casserole, it holds up beautifully for up to 2 months. Betty’s freezing method works well because she either freezes it before baking (assemble completely, cover tightly with plastic wrap and foil, then freeze) or after baking (let it cool completely first). For unbaked frozen casseroles, add an extra 15-20 minutes to the baking time and keep it covered with foil for the first 30 minutes.
For the best texture, I reheat individual portions in the microwave on 50% power for 2-3 minutes, stirring halfway through to ensure even heating. For larger portions, Betty prefers reheating in a 350°F oven covered with foil for about 20-25 minutes until heated through. This method keeps the cracker topping crispy instead of soggy, which is exactly how it should be.

Perfect Partners for Rotisserie Chicken Casserole
- Simple Green Salad: A crisp salad with tangy vinaigrette cuts through the richness of the creamy casserole and adds a fresh, bright contrast that balances every forkful.
- Buttermilk Biscuits: Warm, flaky biscuits are perfect for soaking up any extra sauce left on your plate. Betty’s family always requests these because they turn dinner into a truly comforting experience.
- Roasted Green Beans: Quick-roasted green beans with garlic provide a slightly crispy vegetable side that complements the soft, creamy texture of the casserole beautifully.
- Cranberry Sauce: This might sound unusual, but a small spoonful of cranberry sauce on the side adds a sweet-tart element that Betty discovered makes the chicken flavors pop even more.
- Garlic Bread: Toasted garlic bread gives you another vehicle for enjoying every last bit of that creamy sauce, plus the garlic echoes the flavors already in the casserole.
- Steamed Broccoli: Simple steamed broccoli with a pat of butter adds nutrition and bright green color to your plate without competing with the star of the meal.

FAQs
Absolutely. I recommend assembling the entire casserole up to 24 hours before baking, covering it tightly with plastic wrap, and refrigerating it. Just add 5-10 minutes to the baking time if you’re putting it in the oven straight from the fridge.
Betty’s solution is to use any short pasta you have on hand penne, rotini, shells, or even elbow macaroni work beautifully. The key is to cook them al dente so they don’t turn mushy during baking.
To prevent this issue, make sure you’re not overbaking the noodles initially and don’t skip the resting time after baking. Many home cooks find success with adding an extra splash of milk if the mixture seems thick before baking.
