# Ingredient List:
→ Meats
01 - 2 cups cooked chicken breast, cubed or shredded
→ Vegetables
02 - 4 medium russet potatoes, peeled and diced
03 - 2 cups broccoli florets, chopped
04 - 1 small onion, finely chopped
05 - 2 cloves garlic, minced
→ Dairy & Eggs
06 - 1 cup sour cream
07 - 1 cup shredded cheddar cheese (plus ½ cup for topping)

09 - 2 tablespoons unsalted butter
→ Pantry & Seasonings
10 - 1 teaspoon salt
11 - ½ teaspoon black pepper
12 - ½ teaspoon paprika
13 - ½ teaspoon dried thyme
# How to Make:
01 - Preheat oven to 400°F. Lightly grease a 9x13-inch baking dish with butter or cooking spray.
02 - Bring salted water to a boil in a large pot. Add diced potatoes and cook 8–10 minutes until just fork-tender. Drain thoroughly and set aside.
03 - Steam broccoli florets for 3–4 minutes until bright green and slightly tender but still crisp. Do not overcook.
04 - In a large mixing bowl, combine cooked potatoes, steamed broccoli, chicken, onion, and garlic.
05 - In a separate bowl, whisk together sour cream, milk, melted butter, 1 cup cheddar cheese, salt, pepper, paprika, and thyme until smooth and fully incorporated.
06 - Pour the creamy sauce mixture over the potato, chicken, and broccoli. Fold gently until all ingredients are evenly coated.
07 - Transfer the mixture to the prepared baking dish and spread evenly. Sprinkle remaining ½ cup cheddar cheese over the top.
08 - Bake uncovered for 25–30 minutes until the casserole is bubbly around edges and the cheese topping is golden brown.
09 - Remove from oven and let rest for 5 minutes to set. This makes serving easier and allows the sauce to thicken slightly.
# Expert Tips:
01 -
- Everything cooks in one dish, leaving you with minimal cleanup and maximum comfort
- The sour cream creates this velvety texture that makes every bite feel like a warm hug
02 -
- Overcooking the potatoes during boiling makes them fall apart in the final casserole
- Letting the assembled dish sit for 10 minutes before baking helps the flavors meld together
03 -
- Cheese the dish 5 minutes before baking ends if the top browns too quickly
- Use paper towels to blot excess moisture from broccoli after steaming
