Instructions

Follow these simple steps and you’ll make the casserole in minutes, then let the oven finish the work.

1. Heat the oven and prep the dish
   
   • Set a rack in the center position.
     
   • Turn on a preheated oven to 375 °F / 190 °C.
     
   • Lightly mist a 9 × 13-inch baking dish with cooking spray or brush with a teaspoon of oil.
     
2. Build the chicken mixture
   
   • In a large bowl, add the shredded chicken, cooked rice, broccoli, condensed cream of chicken soup, sour cream, ¾ cup cheddar, Parmesan, garlic powder, onion powder, pepper, and paprika.
     
   • Stir with a sturdy spoon until everything is evenly coated; this creamy blend is your flavorful chicken mixture.
     
3. Fill the casserole dish
   
   • Spread the chicken mixture into the prepared pan, pressing lightly so it reaches every corner. A level surface helps the sauce bubble evenly.
     
4. Add the crunchy topping
   
   • Combine the crushed Ritz cracker crumbs with melted butter in a small bowl. Toss until the crumbs look lightly glossy.
     
   • Sprinkle the buttered crumbs and the remaining ¼-cup cheddar over the top of the casserole—yes, plenty of ritz crackers on top for an irresistible crust.
     
5. Bake to bubbly perfection
   
   • Slide the pan into the center of the preheated oven.
     
   • Bake for 18–22 minutes, or until the cheese melts, the crackers turn golden, and the edges of the filling are visibly bubbling.
     
6. Confirm doneness
   
   • You’ll know the casserole is done when an instant-read thermometer inserted into the center clocks at least 165 °F / 74 °C and the topping is crisp.
     
7. Rest, garnish, and serve
   
   • Remove the dish from the oven and let it stand for 5 minutes; this short rest helps the layers set for cleaner slices.
     
   • Sprinkle with fresh parsley if using.
     
   • Scoop generous portions and enjoy the creamiest, crunchiest rotisserie chicken casserole you’ve ever made.
     

Cleanup tip: Soak the empty pan in warm, soapy water while you eat—the cheesy bits release effortlessly later.

Pro Tips & Variations

Time-Saving Tweaks

• Rotisserie shortcut Skip shredding by buying “pulled rotisserie chicken” from the deli counter—straight into the bowl, zero knife work.
  
• Rice ready-made Use pouch microwave rice; it heats in 90 seconds and slides right into the mix, keeping the total clock close to 30 minutes.
  

Flavor Boosts

• Cheese punch Fold in ¼-cup cream cheese for “million-dollar” richness, or swap half the cheddar for pepper jack if you like gentle heat.
  
• Seasoning spin Stir ½ tsp Cajun or taco seasoning into the chicken mixture for a south-of-the-border lift; sprinkle sliced jalapeños over the crackers for extra kick.
  
• Veggie variety Add diced asparagus or sweet peas for color; a handful of sautéed peppers and onion deepens savoriness without extra cook time.
  

Diet Tweaks

• Lower-carb path Replace white rice with cauliflower rice and sub plain Greek yogurt instead of cream soup plus sour cream. The result is a creamy yet casserole low carb option around 9 g net carbs per serving.
  
• Dark-meat lovers Got leftover chicken thighs? Use them in place of breast meat for extra juicy texture. The smoky notes pair especially well with smoked paprika.
  

Make-Ahead & Freezer Success

• Freeze this casserole Assemble but don’t bake. Wrap tightly in foil, label, and freeze up to 2 months. Bake straight from frozen at 350 °F (175 °C) for about 55 minutes, loosely tenting with foil for the first 30 to prevent over-browning.
  
• Meal-prep portions After baking, cool completely, slice, and pack into single-serve containers. Reheat covered in the microwave (70 % power, 2–3 minutes) or in a 325 °F oven until hot.
  
• Topping on demand If you freeze unbaked, stash the crackers and butter mixture in a small zip bag taped to the pan; scatter it over the casserole right before it hits the oven so the crunch stays lively.
  

Mix-and-match any two tips above to keep this rotisserie chicken casserole fresh and exciting every time it lands on your table.

Serving Suggestions

Build a Balanced Plate

• Bright veggie sides Pair a scoop of the casserole with steamed green beans, roasted carrots, or a simple green bean casserole for extra color and crunch.
  
• Fresh salad contrast A crisp chicken salad with lemon vinaigrette or mixed greens tossed in light Greek-yogurt dressing balances the creamy texture of the main dish.
  
• Bread lovers’ option Warm crusty baguette slices or whole-grain rolls soak up the velvety sauce—ideal for an easy quick dinner spread.
  

Leftover Upgrades

• Stuffed peppers Spoon chilled casserole into halved bell peppers, top with extra cheddar, and bake at 375 °F for 15 minutes.
  
• Loaded burritos Wrap reheated spoonfuls in flour tortillas with shredded lettuce, salsa, and a dash of hot sauce.
  
• Soup starter Thin a cup of leftovers with low-sodium chicken broth, simmer, and finish with a squeeze of lime for a hearty chowder-style bowl.
  

Garnish & Presentation Tips

• Parsley sprinkle A quick hit of chopped parsley right before serving makes each portion pop.
  
• Crunch revival If the cracker topping softens in the fridge, toast leftovers under the broiler for 2 minutes to restore crispness.
  
• Individual ramekins For dinner parties, divide the mixture into single-serve dishes, top, and bake; the personalized portions feel special without extra work.

FAQs

How long is rotisserie chicken good for in a casserole?

Store any baked rotisserie chicken casserole in a shallow, airtight container and refrigerate it within two hours of cooking. When properly cooled and sealed, the dish stays fresh for 3–4 days at 40 °F / 4 °C or below. If you need a longer window, wrap the casserole tightly in two layers of plastic plus foil and freeze for up to 2 months. Thaw overnight in the fridge, then reheat at 325 °F until the center reaches 165 °F (about 20 minutes for individual portions). Discard the casserole if you notice off smells, a sour taste, or visible mold—signs that any chicken, even previously cooked rotisserie meat, has passed its safe-to-eat period.

How long does chicken casserole last?

Across the board, chicken casseroles—whether made with leftover baked chicken, rotisserie shreds, or slow-cooked thighs—share the same cold-storage rules. Refrigerated in a sealed container, the casserole lasts up to four days. For meal-prep efficiency, portion the cooled squares into single-serve glass dishes; they reheat evenly in the microwave (70 % power, 2–3 minutes) or conventional oven (325 °F, loosely covered, 15–20 minutes). If you freeze a fully baked pan, label it with today’s date; enjoy it within 60 days for peak flavor and texture. Always heat leftovers until the internal temperature hits 165 °F to ensure food-safety peace of mind.

What goes in a chicken casserole?

At its simplest, a classic chicken casserole blends four building blocks:

1. Protein — shredded rotisserie chicken, diced chicken breasts, or leftover thighs
   
2. Binder — a creamy element such as cream of chicken soup, sour cream, or plain Greek yogurt
   
3. Carbs and veg — cooked white rice, pasta, or cauliflower rice, plus broccoli, peas, or asparagus
   
4. Seasoning and texture — garlic powder, onion powder, sharp cheddar, and a crisp topping like ritz crackers and butter
   

From there, you can riff endlessly: swap in cream of mushroom soup for earthy depth, choose taco seasoning for a south-western spin, or fold in sautéed peppers and onions for extra savoriness. The key is balancing moisture (so the filling stays creamy) with crunch (so the top of the casserole turns golden and irresistible). Once you master that formula, you can craft winning chicken casseroles with whatever’s on hand—making dinner prep both flexible and foolproof.
