The Ingredients

This recipe uses simple, affordable ingredients that come together beautifully.

For the Casserole:

3 cups cooked chicken, shredded or diced– Use rotisserie chicken for a shortcut.
4 cups broccoli florets – Fresh or frozen both work.
1 can (10.5 ounces) condensed cream of chicken soup – For creaminess and flavor.
1 cup sour cream – For tang and richness.
2 cups shredded cheddar cheese, divided– For a gooey, golden topping.
1 teaspoon garlic powder – For savory depth.
½ teaspoon onion powder – For warmth.
Salt and pepper to taste – For seasoning.

For the Topping:

1 cup crushed buttery crackers (such as Ritz) – For a crispy, golden crust.
¼ cup melted butter – For richness and to help the crackers adhere.

Step-by-Step Instructions

Step 1: Preheat and Prep

Preheat your oven to 350°F and lightly grease a 9×13-inch baking dish.

Pro Tip: A glass baking dish is recommended—it heats evenly and lets you see the beautiful layers forming.

Step 2: Prepare the Broccoli

If using fresh broccoli, blanch it in boiling water for 2-3 minutes, then drain well. If using frozen broccoli, thaw and drain it well.

Pro Tip: Draining the broccoli well prevents the casserole from becoming watery.

Step 3: Mix the Filling

In a large bowl, combine the cooked chicken, broccoli, cream of chicken soup, sour cream, 1½ cups of the cheddar cheese, garlic powder, onion powder, salt, and pepper. Stir until evenly combined.

Pro Tip: Mix well so every bite has a good ratio of chicken, broccoli, and sauce.

Step 4: Assemble the Casserole

Spread the mixture evenly into the prepared baking dish. Sprinkle the remaining ½ cup of cheddar cheese over the top.

Pro Tip: Spread the mixture evenly for uniform baking.

Step 5: Make the Topping

In a small bowl, combine the crushed crackers and melted butter. Stir until the crackers are evenly coated. Sprinkle the mixture evenly over the top of the casserole.

Pro Tip: Don’t press the topping down—leave it loose for a crispy, golden crust.

Step 6: Bake to Golden Perfection

Bake for 25 to 30 minutes, until hot and bubbly and the topping is golden brown.

Pro Tip: Watch the topping closely toward the end—it can go from golden to burnt quickly.

Step 7: Rest and Serve

Let the casserole rest for 5 minutes before serving.

Pro Tip: The rest time allows the casserole to set and makes it easier to scoop.
