Ingredients

(Tip: You can find the complete list of ingredients and their measurements in the recipe card below.)

Chicken breast provides lean, tender protein that absorbs the garlic Parmesan flavors beautifully.

Steak, such as sirloin or ribeye, adds richness and a hearty, beefy contrast to the chicken.

Potatoes form the base of the dish, mashed until smooth and creamy for a comforting foundation.

Butter enhances richness in both the mashed potatoes and the baked topping.

Heavy cream or milk creates smooth, velvety mashed potatoes without dryness.

Garlic delivers bold aroma and savory depth throughout the entire dish.

Parmesan cheese adds sharpness and umami, especially in the baked topping.

Mozzarella cheese contributes meltability and that irresistible cheese pull.

Cheddar cheese deepens flavor and reinforces the “loaded” potato profile.

Olive oil helps sear the meats and prevents sticking.

Salt balances and enhances every layer of the dish.

Black pepper adds gentle warmth and seasoning.

Italian seasoning brings subtle herb notes that complement both chicken and steak.

Sour cream adds tang and creaminess to the mashed potatoes.

Green onions provide freshness and mild bite for balance.

Bacon bits add smoky richness and texture to the mashed potatoes.

Fresh parsley finishes the dish with color and brightness.

Directions

Begin by preheating the oven to 190°C and greasing a large baking dish. Peel and boil the potatoes in salted water until fork-tender. Drain well and mash with butter, cream, sour cream, cheddar cheese, bacon bits, salt, and pepper until smooth. Spread the mashed potatoes evenly into the prepared baking dish.

Season the chicken and steak with salt, pepper, and Italian seasoning. Heat olive oil in a skillet over medium-high heat and quickly sear the chicken and steak separately until lightly browned. They do not need to be fully cooked at this stage. Arrange the meats evenly over the mashed potatoes.

In a small bowl, mix melted butter, garlic, Parmesan cheese, and parsley. Spoon this mixture evenly over the chicken and steak. Sprinkle mozzarella cheese across the top. Bake uncovered until the meats are cooked through and the top is golden and bubbly. Allow the dish to rest briefly before serving.

Variations and Customizations

This dish is very adaptable. You can use chicken thighs instead of breasts for extra juiciness or swap steak for ground beef if preferred. I tested a version with roasted garlic mixed into the potatoes, which added incredible depth. For a lighter variation, reduce the cheese slightly and use milk instead of cream. You may also add sautéed mushrooms or spinach between the potato and meat layers for extra flavor and nutrition. Spicy seasoning blends can be added for a bolder profile.
