Ingredients You’ll Need

• 2 cups cooked chicken, shredded or chopped
• 2 cups broccoli florets (fresh or frozen)
• 1 can cream of chicken soup
• ½ cup sour cream
• ½ cup mayonnaise (yes, trust the process)
• 1 teaspoon lemon juice
• ½ teaspoon garlic powder
• ½ teaspoon black pepper
• 1 cup shredded cheddar cheese
• ½ cup grated Parmesan cheese
• ½ cup breadcrumbs or crushed crackers
• 2 tablespoons melted butter

Optional extras:

• Cooked rice (for a heartier base)
• Mushrooms or onions
• Extra cheese (because obviously)

Step-by-Step Instructions

1. Preheat your oven.
Set your oven to 180°C (350°F). Lightly grease a baking dish so nothing sticks.

2. Prepare the broccoli.
Steam or microwave broccoli until slightly tender. You don’t want it mushy—just softened.

3. Mix the creamy sauce.
In a bowl, combine cream of chicken soup, sour cream, mayonnaise, lemon juice, garlic powder, and black pepper. Stir until smooth.

4. Assemble the casserole.
Spread broccoli in the bottom of the dish. Add cooked chicken on top.

5. Add the sauce.
Pour the creamy mixture over everything. Spread evenly so every bite gets coated.

6. Add cheese.
Sprinkle cheddar and Parmesan cheese over the top.

7. Add the crunchy topping.
Mix breadcrumbs with melted butter and sprinkle over the casserole.

8. Bake.
Bake for 25–30 minutes until bubbly and golden on top.

9. Let it rest.
Cool for a few minutes before serving. This helps everything set (and saves your tongue).

Common Mistakes to Avoid

Skipping the broccoli pre-cook. Raw broccoli stays crunchy… and not in a good way.

Using dry chicken. This dish loves juicy, tender chicken—rotisserie works great.

Overbaking. You want bubbly and golden, not dried out.

Forgetting seasoning. Even creamy casseroles need a little flavor boost.

Not letting it rest. Cutting too early = casserole soup.

Alternatives & Substitutions

No cream of chicken soup? Use cream of mushroom or make a quick homemade white sauce.

Want it lighter? Swap mayo with Greek yogurt. It still works, promise.

No chicken? Try turkey or even tofu for a vegetarian twist.

Gluten-free? Use GF breadcrumbs or skip the topping altogether.

IMO, adding a layer of cooked rice at the bottom turns this into a full, hearty meal.
