Ingredients

• 3 cups cooked shredded chicken (rotisserie works great)
• 4 cups cooked long-grain rice (white or brown)
• 3 cups broccoli florets (fresh or frozen, bite-size)
• 1 small onion, diced
• 3 cloves garlic, minced
• 2 tablespoons unsalted butter
• 1 tablespoon olive oil
• 3 tablespoons all-purpose flour
• 1 cup low-sodium chicken broth
• 1 1/2 cups milk (whole or 2%)
• 1 teaspoon Dijon mustard
• 1 teaspoon paprika
• 1 1/2 teaspoons kosher salt, divided (adjust to taste)
• 1 teaspoon black pepper, divided
• 2 cups shredded sharp cheddar cheese
• 1/2 cup grated Parmesan
• 1/2 cup sour cream (or plain Greek yogurt)
• 1 cup panko breadcrumbs
• 2 tablespoons melted butter (for the topping)
• Optional add-ins: 1 cup frozen peas, 1 cup sliced mushrooms, 1/4 teaspoon crushed red pepper

Let’s Get Cooking – Instructions

1. Preheat the oven to 375°F. Lightly grease a 9×13-inch baking dish. If using frozen broccoli, measure it out now so it starts to thaw.
2. Sauté aromatics. In a large skillet over medium heat, add olive oil. Cook the diced onion with 1/4 teaspoon salt for 4–5 minutes until translucent. Add garlic and cook 30 seconds until fragrant.
3. Make the quick sauce. Add 2 tablespoons butter to the skillet. Once melted, sprinkle in flour and whisk for 1 minute. Slowly pour in chicken broth and milk, whisking constantly to smooth out lumps.
4. Season and enrich. Whisk in Dijon, paprika, 1/2 teaspoon salt, and 1/2 teaspoon pepper. Simmer 3–4 minutes until the sauce thickens and coats a spoon. Turn off heat; stir in cheddar and Parmesan until melted. Fold in sour cream.
5. Assemble the casserole. In a large bowl, combine cooked rice, shredded chicken, broccoli, optional peas/mushrooms, and the cheese sauce. Taste and adjust seasoning with remaining salt and pepper.
6. Transfer to the dish. Spread the mixture evenly in the prepared 9×13. If it looks dry, splash in 2–3 tablespoons broth or milk—it should be creamy, not soupy.
7. Mix the topping. Stir panko with 2 tablespoons melted butter (and a pinch of paprika or Parmesan if you like). Sprinkle over the casserole for crunch.
8. Bake. Cover loosely with foil and bake 15 minutes. Remove foil and bake another 12–15 minutes until bubbling at the edges and golden on top.
9. Rest (yes, really). Let the casserole sit 10 minutes. This helps it set, keeps slices neat, and saves you from molten-cheese chaos.
10. Finish and serve. Optional: drizzle with a little olive oil, scatter chopped parsley, and hit with a squeeze of lemon for brightness. Serve hot and accept compliments.

Preservation Guide

• Store: Cool completely, then cover and refrigerate up to 4 days. For best texture, keep the topping separate if making ahead.
• Reheat: Oven at 350°F, covered for 15–20 minutes; uncover for 5 minutes to re-crisp. Microwave individual portions 2–3 minutes (FYI the topping softens).
• Freeze unbaked: Assemble without the panko. Wrap tightly and freeze up to 3 months. Thaw overnight, add topping, then bake as directed.
• Freeze baked leftovers: Portion and wrap well. Reheat straight from frozen at 325°F, covered 25–30 minutes. Ensure the center hits 165°F for food safety.
• Moisture insurance: If reheating seems dry, stir in a splash of broth or milk before baking.

Nutritional Perks

• Protein-packed: Chicken plus cheese deliver satisfying protein to keep you full longer.
• Veggie boost: Broccoli brings fiber, vitamin C, and a bit of crunch to balance the creaminess.
• Smart carbs: Rice provides steady energy; swap in brown rice or quinoa for extra fiber if you want.
• Calcium hit: Cheeses and milk support bone health—comfort food with benefits.
• Ballpark nutrition (per serving): ~560–680 calories, 35–45g protein, 55–70g carbs, 18–28g fat. Exact numbers vary based on your swaps.

Common Mistakes to Avoid

• Watery sauce: Skipping the roux or under-simmering leaves you with soup. Cook the flour for 1 minute, then reduce the sauce until it thickens.
• Overcooked veggies: Tiny broccoli florets turn mushy fast. Keep them bite-size and don’t pre-cook; the oven finish is enough.
• Unseasoned base: Cheesy doesn’t equal flavorful. Salt and pepper in stages—aromatics, sauce, and assembly—so the whole dish sings.
• Dry casserole: Using day-old rice without extra liquid can be a chokehold. Add broth or milk as needed for a creamy mix.
• Topping fails: Bare crumbs burn. Toss panko with melted butter and add it halfway if your oven runs hot.
• No rest period: Cutting immediately = cheesy landslide. Give it 10 minutes to set, then slice confidently.
• Wrong pan size: Overcrowding prevents bubbly goodness. A 9×13 is your friend for even heat and proper crust.

Alternatives

• Taco Beef Bake: Swap chicken for 1 lb browned ground beef. Use 2 cups salsa + 1 cup broth in the sauce, add black beans and corn, top with pepper jack.
• Tuna Noodle Classic: Replace rice with 12 oz cooked egg noodles and chicken with 2 cans tuna. Add peas, extra dill, and a lemony panko top.
• Veggie Enchilada Casserole: Use cooked quinoa, roasted peppers, zucchini, and black beans. Sauce with enchilada sauce + a bit of cream; finish with cotija and cilantro.
• Buffalo Chicken Bake: Stir 1/3 cup buffalo sauce into the cheese sauce. Top with blue cheese crumbles and celery leaves for a spicy twist.
• Gluten-free: Use GF panko and swap flour for cornstarch (2 tablespoons whisked into the cold milk, then simmer). Ensure broth is certified GF.
• Dairy-free: Make a cashew cream (blend 1 cup soaked cashews with 1 1/2 cups broth). Use DF cheese or nutritional yeast; skip sour cream.
• Low-carb: Replace rice with 5 cups riced cauliflower. Reduce broth by 1/4 cup to prevent excess moisture.
• Breakfast-for-dinner: Add 6 whisked eggs and crumble in cooked breakfast sausage. Bake until set; it’s a frittata-casserole hybrid and yes, it slaps.

FAQ

Can I prep this casserole a day ahead?

Absolutely. Assemble the casserole without the panko, cover, and refrigerate up to 24 hours. Add the topping right before baking and extend bake time by 5–10 minutes since it starts cold.

Is rotisserie chicken okay to use?

Yes, it’s perfect. Shred it while warm for easy handling, and taste the mixture before baking—rotisserie can be saltier, so adjust seasoning accordingly.

Should I use fresh or frozen broccoli?

Both work. Fresh stays a bit firmer; frozen is easier. If using frozen, don’t thaw fully—just break it up and fold in so it doesn’t release too much water.

Can I use uncooked rice instead of cooked?

You can, but tweak the method. Add 1 1/2 cups uncooked rice plus 3 cups broth, cover tightly with foil, and bake 40–45 minutes. Remove foil, stir, then top and finish baking 10–15 minutes.

How do I prevent the casserole from being bland?

Season in layers. Salt the onions, season the sauce with mustard, paprika, and pepper, then taste the mixture before baking. A squeeze of lemon or dash of hot sauce after baking brightens everything.

Can I skip the homemade sauce and use condensed soup?

Yes. Replace the roux, milk, and broth with 2 cans condensed cream of chicken (or mushroom) plus 1 cup milk. It’s faster, though IMO the homemade version tastes richer.

What pan size should I use?

A 9×13-inch baking dish is ideal for even heat and a great crust. If you use a deeper dish, add 5–10 minutes to bake time and check for bubbling edges.

How do I keep the crumb topping crisp?

Toss panko with melted butter and bake uncovered for the last 12–15 minutes. If reheating leftovers, broil 1–2 minutes at the end to revive the crunch (watch closely!).

Can I make this vegetarian?

Definitely. Swap chicken for 2 cups cooked lentils or a mix of mushrooms and chickpeas. Keep the sauce and cheese as written, or use dairy-free alternatives for a vegan version.

What’s the best way to freeze individual portions?

Scoop cooled casserole into airtight containers or wrap squares tightly in foil. Label with date and reheat at 325°F, covered, until the center reaches 165°F. Easy grab-and-go dinners for busy weeks.
