Ingredients

- 2 cups cooked chicken breast, diced
- 1 head of broccoli, cut into florets
- 1 cup sour cream or Greek yogurt

- 2 cups shredded cheddar cheese, divided

How to Make It
1. Preheat the oven
Set your oven to 375°F (190°C) and lightly grease a 9×13-inch baking dish.
2. Boil the potatoes
In a large pot, boil the cubed potatoes in salted water for about 10 minutes, or until fork-tender. Drain and set aside.
3. Blanch the broccoli
Bring fresh water to a boil in the same pot, then blanch the broccoli florets for 3 minutes. Drain and set aside.
4. Mix the creamy sauce
In a large mixing bowl, stir together sour cream, milk, 1 cup of shredded cheddar cheese, garlic powder, onion powder, salt, and pepper until smooth.
5. Combine everything
Gently fold the cooked potatoes, diced chicken, and broccoli into the sauce until evenly coated. Spoon the mixture into the prepared baking dish.
6. Add the cheesy topping
Sprinkle the remaining 1 cup of cheddar cheese over the casserole. In a small bowl, mix the breadcrumbs with melted butter and sprinkle on top.
7. Bake
Bake uncovered for 20–25 minutes, or until the top is golden brown and the casserole is hot and bubbly.
8. Cool and serve
Let the casserole rest for 5 minutes before serving. Enjoy!
Tips and Variations
- Make it vegetarian: Skip the chicken and load it up with more veggies like mushrooms, cauliflower, or peas.
- Use rotisserie chicken: A great time-saver for busy nights!
- Add spice: Stir in a pinch of red pepper flakes or a dash of hot sauce to the sauce for extra flavor.
- Swap cheeses: Try mozzarella, Monterey Jack, or a sharp white cheddar.
Storage
Store leftovers in an airtight container in the fridge for up to 3 days. Reheat in the oven or microwave until warmed through.
