Ingredients
Main Ingredients
- 2 cups shredded cooked chicken (rotisserie or poached and shredded) Rotisserie chicken adds flavor and speeds up the process.
- 3 cups broccoli florets (about 8–10 oz) Fresh broccoli gives the best texture; frozen broccoli can be used but should be well-drained.
- 4 oz cream cheese, softened Soften at room temperature for best melting results.
- 1 cup shredded cheddar cheese, divided Extra cheese can be added for a cheesier top.
- 1/2 cup heavy cream Can be swapped with half-and-half for a lighter sauce.
- 1/2 teaspoon garlic powder
- 1/2 teaspoon onion powder
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
- 1 tablespoon butter For greasing the baking dish.
Instructions
Preparation
- Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish with butter or nonstick spray.
- Steam 3 cups of broccoli florets until just tender, about 4–6 minutes depending on size. Drain thoroughly and let sit in a colander to remove excess water.
Making the Sauce
- In a medium saucepan over low–medium heat, melt 1 tablespoon of butter. Add 4 oz of softened cream cheese and 1/2 cup of heavy cream. Whisk until smooth and creamy.
- Stir in 1/2 teaspoon garlic powder, 1/2 teaspoon onion powder, 1/2 teaspoon salt, and 1/4 teaspoon black pepper. Taste and adjust seasoning as necessary.
Combining the Ingredients
- In a large bowl, toss 2 cups of shredded cooked chicken and the drained broccoli with the cream cheese sauce until evenly coated.
Baking
- Transfer the mixture to the prepared baking dish and spread it out evenly. Sprinkle 1 cup of shredded cheddar cheese over the top.
- Bake for 20–25 minutes, until the casserole is bubbly and the edges are set. Broil on high for 1–2 minutes for a golden, slightly crisp top, watching closely to prevent burning.
Serving
- Let the casserole rest for 5 minutes before serving so it firms up slightly.
Notes
This casserole stores well. Refrigerate leftovers in an airtight container for 3-4 days. It can be frozen for up to 2 months. Reheat in the oven or microwave before serving. For a lighter version, consider swapping ingredients as suggested in the notes and substitutions section above.
