Introduction
If you’ve ever been to a potluck, family gathering, church supper, or holiday get-together and watched one dish vanish before anything else, you know the power of a truly crowd-pleasing casserole. This Cheesy Chicken Broccoli Casserole is exactly that dish for me—I’ve brought it to so many events over the years that friends now jokingly call it “Aymane’s Famous Thing.” What makes it legendary? It’s ridiculously easy, uses just four core ingredients, comes together in minutes, feeds a crowd affordably, and delivers maximum comfort: tender shredded chicken, vibrant broccoli, creamy condensed soup base, and gooey melted cheddar cheese all baked into one bubbly, golden masterpiece.
The beauty lies in its simplicity—no fancy techniques, no long ingredient lists, no stress. Yet it tastes like you put in way more effort than you did. The chicken stays juicy, the broccoli adds freshness and nutrition without overpowering, the soup creates that signature creamy texture, and the cheese… oh, the cheese browns beautifully on top for those irresistible crispy edges everyone fights over.
This recipe has roots in classic mid-century American comfort food—think church potlucks of the 1950s–70s when casseroles were king, using pantry staples like canned soup for convenience. Over time, it evolved into a modern favorite because it’s budget-friendly (often under $15 for 8–10 servings), customizable, and reliably delicious. Whether you’re a beginner cook or a busy parent, this is the dish that makes you look like a pro with minimal work.

- Prep in 10 minutes, bake while you get ready
- Travels perfectly in a foil pan—no spills, reheats like a dream
- Kid-approved, adult-loved, veggie-hidden

In this massive guide, we’ll dive deep: exact ingredients with substitutions, foolproof steps, pro tips from years of making it, variations to keep it exciting, storage/freezing advice, nutritional breakdown, pairing ideas, and even why it works so well scientifically (hello, Maillard reaction on that cheese top!).
Ingredients (Serves 8–10 as a main or 12+ as a side)
Core 4-ingredient magic:
- 4–5 cups cooked, shredded chicken (about 2 lbs raw boneless skinless breasts or thighs; rotisserie chicken is perfect for ease—skin removed, meat pulled)
- 4–5 cups broccoli florets (fresh or frozen; if frozen, no need to thaw fully—about 24–32 oz bag)
- 2 (10.5 oz) cans condensed cream of chicken soup (low-sodium if preferred; cream of mushroom or celery works too for variety)
- 3–4 cups shredded sharp cheddar cheese (divided; freshly shredded melts better than pre-shredded, which has anti-caking agents)
Optional boosters for extra flavor (these don’t count toward the “4 ingredients” claim but elevate it):
- ½–1 cup sour cream or plain Greek yogurt (for tang and creaminess)
- ½ teaspoon garlic powder
- ½ teaspoon onion powder
- ¼ teaspoon black pepper
- ¼ teaspoon paprika or smoked paprika
- Salt to taste (canned soup and cheese are salty, so go light)
For topping (highly recommended for potluck wow factor):
- 1–2 cups extra shredded cheddar or a mix with mozzarella/Parmesan
- 1 cup crushed Ritz crackers, buttery breadcrumbs, or French fried onions (mixed with 2–3 Tbsp melted butter)
Equipment Needed
- Large mixing bowl
- 9×13-inch baking dish (or two smaller ones for sharing)
- Aluminum foil pan for transport
- Wooden spoon or spatula
- Oven preheated to 375°F (190°C)
Step-by-Step Instructions
- Preheat and prep (5 minutes)
Set your oven to 375°F. Lightly grease a 9×13-inch baking dish with butter or cooking spray (or use disposable foil for zero cleanup and easy transport). If using fresh broccoli, chop into bite-sized florets. If frozen, rinse quickly under cool water to remove ice crystals (helps prevent watery casserole). - Cook or shred the chicken (if not using rotisserie)
For raw chicken: Poach or bake 2 lbs breasts/thighs until 165°F internal temp (about 20–25 minutes). Cool slightly, then shred with two forks or your hands. Rotisserie shortcut: Buy one large or two small chickens, remove skin, shred meat (yields about 4–5 cups). Pro tip: Shred while warm—easier and absorbs flavors better. - Mix the filling (5 minutes)
In a large bowl, combine shredded chicken, broccoli florets, both cans of cream of chicken soup (undiluted), and 2–2.5 cups of the shredded cheddar. Add sour cream (if using) and seasonings: garlic powder, onion powder, pepper, paprika. Stir gently but thoroughly until everything is evenly coated in the creamy soup mixture. Taste a small bite—adjust salt/pepper if needed (soup is salty, so usually minimal). - Assemble the casserole
Spread the mixture evenly into the prepared baking dish. Smooth the top with your spoon. Sprinkle remaining 1–1.5 cups cheddar cheese generously over the surface—this creates that golden, bubbly crust everyone loves. - Add topping (optional but recommended)
For extra crunch: Mix crushed crackers or breadcrumbs with melted butter and scatter over cheese. This adds texture contrast—creamy inside, crispy top. - Bake to perfection (30–40 minutes)
Cover loosely with foil (prevents over-browning early) and bake 20 minutes. Remove foil, bake another 10–20 minutes until bubbling at edges, cheese is fully melted and golden-brown with spots, and broccoli is tender. If top browns too fast, tent foil again. Let rest 5–10 minutes before serving—sets up nicely and prevents burns. - Serve and wow the crowd
Scoop generous portions. Pairs beautifully with simple sides (see below). Watch it disappear!
Pro Tips for Potluck Success
- Use rotisserie chicken to save time—it’s the secret to “only 4 ingredients” feeling effortless.
- Don’t overcook broccoli pre-bake; it softens perfectly in the oven.
- Shred cheese yourself—melts smoother, better flavor.
- For transport: Bake ahead, cool, cover tightly, reheat at event (325°F covered 20–30 min).
- Prevent sogginess: If using frozen broccoli, pat dry after quick rinse.
- Cheese variations: Sharp cheddar for bite, mild for kids, add Parmesan for umami.
- Make it less “soupy”: Use one can soup + ½ cup sour cream for thicker texture.
Variations to Keep It Fresh
- Rice-boosted version: Add 2 cups cooked rice to stretch further (classic comfort upgrade).
- Healthier twist: Use low-fat soup, Greek yogurt instead of sour cream, reduced-fat cheese, add spinach.
- Spicy kick: Mix in diced jalapeños, hot sauce, or cayenne.
- No-chicken vegetarian: Swap chicken for white beans, chickpeas, or extra broccoli/mushrooms.
- Creamier deluxe: Stir in 4 oz cream cheese or ½ cup heavy cream.
- Topping swaps: Panko + butter, crushed cornflakes, or no topping for simplicity.
- Mini versions: Bake in muffin tins for individual portions—great for parties.
Make-Ahead and Storage
- Assemble up to 24 hours ahead: Cover unbaked, refrigerate. Add 10–15 min bake time.
- Fully baked leftovers: Store airtight in fridge 3–4 days. Reheat covered at 350°F with splash milk/cream.
- Freezer-friendly: Bake, cool completely, wrap tightly (foil + plastic), freeze up to 2–3 months. Thaw overnight, reheat covered.
- Potluck pro: Bake in foil pan, transport warm in insulated bag.
