- 1 medium yellow onion, chopped (about 1 cup / 150g)
- 2 tablespoons olive oil (30ml)
- 1/2 teaspoon salt (2.5ml)
- 1/4 teaspoon black pepper (1.25ml)
- 1/4 teaspoon garlic powder (1.25ml)
- 4 tablespoons unsalted butter (57g)
- 4 tablespoons all-purpose flour (30g)
- 2 cups whole milk (475ml), warmed slightly

Instructions:
- Sauté chopped onion in olive oil in a large skillet until softened. Add broccoli florets, salt, pepper, and garlic powder. Cook until broccoli is slightly tender-crisp.

- Add shredded chicken and the cooked onion and broccoli mixture to the creamy cheese sauce. Stir to combine, making a rich chicken broccoli casserole filling.
- Pour the chicken and broccoli mixture into the prepared 9x13 inch baking dish.
- In a small bowl, combine crushed crackers and melted butter.
- Sprinkle the cracker topping evenly over the chicken and broccoli mixture.
- Bake in a preheated oven (375°F / 190°C) for 25-30 minutes, or until golden brown and bubbly, creating the perfect chicken broccoli casserole.
