Broccoli can be swapped for nearly any veggie so this recipe flexes with what’s in my fridge I always find grating my own cheddar takes it from good to great plus the kitchen smells incredible as it bakes

Storage Tips

Keep leftovers in a sealed container in the fridge for three to four days. Reheat portions in the oven for crispiness or use a microwave for lunches. For longer storage freeze in single portions and thaw overnight for an easy meal later.

Ingredient Substitutions

If you do not have chicken breast use chicken thighs or diced rotisserie chicken for more flavor and tenderness. The potatoes can be replaced with sweet potatoes or cauliflower for a twist. Out of cheddar cheese blend mozzarella or pepper jack into the mix for a new flavor profile.

Serving Suggestions

Serve this casserole straight from the dish alongside a crisp green salad or roasted carrots. It also makes a filling lunch for meal prep. Crumble bacon or a handful of crispy onions on top for those who love extra crunch.

How to Make It

Instruction 01

Preheat oven to 190°C. Cut chicken and potatoes into uniform 2.5 cm cubes. Prepare broccoli by cutting into small florets if necessary.

Instruction 02

In a large mixing bowl, add diced chicken, potatoes, broccoli, grated cheddar, chicken broth, melted butter, garlic powder, salt, and pepper. Mix thoroughly to ensure even coating.

Instruction 03

Lightly grease a large ovenproof dish. Transfer the mixture into the dish, spreading evenly. Cover securely with foil to retain moisture. Bake in the preheated oven for 45 minutes.

Instruction 04

Remove foil. Continue baking uncovered for an additional 15 minutes, allowing the cheese to form a golden crust and the edges to bubble.

Additional Tips

  1. Dice chicken and potatoes evenly to ensure consistent cooking throughout the dish.
  2. The foil cover is essential for preventing dryness; uncovering at the end gives you a rich, caramelized topping.
  3. For extra creaminess, stir 60 ml of heavy cream or a spoonful of sour cream into the mixture before baking.
  4. Test with a thermometer—chicken should reach 74°C for food safety.
  5. For variety, substitute broccoli with peas or corn, or add sautéed onions or mushrooms before baking.
