Ingredients

Scale
  • 4 cups Yukon Gold or Russet potatoes, peeled and diced (about 650g)
  • 2 large boneless, skinless chicken breasts (about 1 lb), cut into 1-inch pieces
  • 3 cups broccoli florets (about 300g), fresh or frozen (thawed and dried if frozen)
  • 1 cup sour cream (240g)
  • 1/3 cup mayonnaise (80g)
  • 1/2 cup chicken broth (120ml)
  • 1 teaspoon garlic powder
  • 1/2 teaspoon onion powder
  • 1/2 teaspoon salt (or to taste)
  • 1/2 teaspoon black pepper (or to taste)
  • 1 1/2 cups shredded cheddar cheese (170g)
  • 1 cup shredded mozzarella cheese (110g)
  • 2 tablespoons chopped fresh parsley (optional)

Instructions

  1. Preheat oven to 400°F (200°C).
  2. Peel and dice potatoes into 1-inch cubes and place in a large mixing bowl.
  3. Cut chicken breasts into 1-inch pieces and pat dry.
  4. Chop broccoli florets into bite-sized pieces. If using frozen, thaw and dry thoroughly.
  5. In a separate bowl, whisk together sour cream, mayonnaise, chicken broth, garlic powder, onion powder, salt, and pepper until creamy.
  6. Add chicken, potatoes, and broccoli to the sauce bowl and toss to coat evenly. Adjust seasoning if needed.
  7. Lightly grease a 9×13-inch baking dish. Spread mixture evenly in the dish and press down gently.
  8. Sprinkle cheddar and mozzarella cheese evenly over the top.
  9. Bake uncovered for 35-40 minutes, until the top is golden and bubbly and potatoes are fork-tender. If cheese browns too quickly, cover loosely with foil.
  10. Remove from oven and let rest for 10 minutes before serving. Garnish with chopped parsley if desired.

Notes

For a low-carb version, swap potatoes for cauliflower. Use rotisserie chicken for faster prep. Add extra veggies like bell peppers or spinach if desired. Let casserole rest after baking for best texture. Use dairy-free cheese and plant-based yogurt for allergy-friendly adaptation.
