• Servings: 4–6

Ingredients (with metric conversions)

• 2 tbsp butter (≈ 28 g)

• 2 boneless skinless chicken breasts or 2 cups diced rotisserie chicken (about 450–550 g raw breasts; rotisserie ≈ 300–350 g cooked)

• 1 tsp Italian seasoning

• Salt & pepper, to taste

• 2½ cups chicken broth (≈ 600 ml)

• 1 tbsp olive oil

• 1¼ cups white long-grain rice, uncooked (≈ 230 g)

• 2 cups fresh broccoli florets, uncooked (≈ 180 g)

• 10.5 oz condensed cream of chicken soup (≈ 298 g)

• ½ cup milk (≈ 120 ml)

• ½ cup sour cream (≈ 120 ml)

• 2 cups shredded cheddar cheese, divided (≈ 226 g)
  Optional seasonings: ½ tsp dried thyme, ½ tsp garlic powder
  Casserole topping: 1 cup Ritz crackers, crushed (≈ 120 g), 2 tbsp melted butter (≈ 28 g)

Equipment & prep

• 9×13-inch (23×33 cm) casserole dish (greased)

• Medium heavy pot with lid (for cooking rice & broccoli)

• Skillet (if cooking raw chicken)

• Mixing bowl and whisk or spoon

• Measuring cups, knife, cutting board, fork for shredding (if needed)

Preheat oven to 350°F / 175°C before assembling the casserole.

Step-by-step directions (detailed)

1. Prep the chicken.

   • If using raw chicken breasts: cut into bite-sized pieces and season with Italian seasoning, salt, and pepper.

   • If using rotisserie chicken: dice or shred and set aside.

2. Brown the chicken (if using raw).

   • In a medium pot or skillet, melt 2 tbsp butter over medium heat. Add 1 tbsp olive oil (helps prevent burning). Cook the seasoned chicken pieces until golden and mostly cooked through, about 4–6 minutes. Remove chicken to a plate and set aside. (If using rotisserie chicken, skip this step.)

3. Cook the rice (and broccoli).

   • In the same pot (no need to clean), pour in 2½ cups (600 ml) chicken broth and bring to a boil over high heat.

   • Stir in 1¼ cups (230 g) white long-grain rice, reduce heat to low, cover, and simmer 6 minutes (per your original method).

   • After 6 minutes, add 2 cups (180 g) fresh broccoli florets on top (do not stir), cover, and continue cooking 9 more minutes — or until the rice is tender and liquid is absorbed. (Total stovetop rice time ≈ 15 minutes.)

   Note: This method steams the broccoli on top of the rice so both finish at the same time. If you prefer firmer broccoli, add it for the last 6–8 minutes instead.

4. Combine the creamy mixture.

   • Turn off heat. To the pot with rice and broccoli, stir in the browned chicken (or rotisserie chicken), 10.5 oz (≈298 g) condensed cream of chicken soup, ½ cup (120 ml) milk, ½ cup (120 ml) sour cream, optional ½ tsp dried thyme and ½ tsp garlic powder, and 1 cup (≈113 g) of the shredded cheddar cheese (reserve the other cup for topping). Mix until combined and smooth. Taste and adjust salt/pepper (remember the soup adds salt).

5. Assemble in casserole dish.

   • Transfer the mixture into the greased 9×13-inch casserole dish and spread evenly. Sprinkle the reserved 1 cup (≈113 g) shredded cheddar evenly over the top.

6. Bake covered.

   • Cover the dish (foil or lid) and bake at 350°F / 175°C for 15 minutes.

7. Add cracker topping & finish baking.

   • While the casserole bakes, prepare the topping: mix 1 cup crushed Ritz crackers (≈120 g) with 2 tbsp melted butter (≈28 g) until crumbs are moistened.

   • After 15 minutes, remove the cover, sprinkle the cracker topping evenly, and bake uncovered for an additional 10 minutes, or until the topping is golden and the casserole is bubbling at the edges.

8. Rest & serve.

   • Let the casserole sit for 5 minutes before serving — this helps it set and makes portioning cleaner.

Pro tips & troubleshooting

• Rice texture: This recipe uses a 1:2 rice:liquid ratio (1¼ cup rice : 2½ cup broth). If your rice brand runs dry or sticky, check it a couple minutes earlier. If rice is undercooked after the total stovetop time, add 1–2 tbsp extra hot broth, cover, and rest 5 minutes.

• Broccoli doneness: Add broccoli later (last 6–8 minutes) for firmer florets, earlier for softer ones. Cut broccoli into uniform pieces for even cooking.

• If mixture is too thin: Stir in 1–2 tbsp instant rice (or 1 tbsp cornstarch slurry: 1 tbsp cornstarch + 1 tbsp cold water) and heat briefly before transferring to the baking dish.

• Prevent soggy topping: Make sure the cracker crumbs are well coated in butter so they toast quickly. Broil 30–60 seconds at the end if you want extra crunch — watch closely.

• Cheese melt: Use freshly shredded cheddar (not pre-shredded) for the creamiest melt — pre-shredded often contains anti-caking agents that make the sauce slightly grainy.

Variations & substitutions

• Rotisserie shortcut: Use 2 cups diced rotisserie chicken and skip the browning step — great for weeknights.

• Low-fat option: Use low-fat sour cream and 2% milk; swap half the cheddar for reduced-fat cheddar.

• Gluten-free: Use gluten-free crackers or crushed gluten-free breadcrumbs for the topping, and confirm the cream of chicken soup is GF (or use a GF substitute).

• Add-ins: Stir in 1 cup cooked mushrooms, ½ cup frozen corn, or ½ cup sun-dried tomatoes for extra flavor. Crumbled bacon on top adds a smoky crunch.

• Whole grain: Use brown rice but cook separately ahead of time (brown rice needs longer and more liquid — about 2:1.5 ratio and ~45 min cook time).

Make-ahead, storage & reheating

• Make-ahead (best): Assemble through step 5, cover tightly, refrigerate up to 24 hours, then top and bake as directed.

• Refrigerate: Store leftovers in an airtight container for 3–4 days.

• Freeze: For best texture, freeze before baking (assembled but unbaked) up to 2 months. Thaw overnight in the fridge and bake as directed, adding a few extra minutes as needed. Baked casserole can be frozen but cheese/dairy texture may change.

• Reheat: Warm individual portions in the microwave (1–2 minutes) or reheat the whole dish covered at 350°F / 175°C for 20–25 minutes until hot; broil briefly to crisp the topping.

Serving suggestions

• Serve with a crisp green salad or steamed green beans for a lighter plate.

• Offer crusty bread or garlic bread on the side to mop up the creamy sauce.

• Make it a full meal by adding a side of roasted sweet potatoes or a simple slaw.

enjoy!
