directions
Preheat oven:
Preheat your oven to 400°F (200°C).
Prepare the mashed potatoes:
In a large pot, bring water to a boil and add the cubed potatoes. Boil for about 10 minutes or until fork-tender. Drain and return the potatoes to the pot.
Mash and season:
Mash the potatoes with butter, heavy cream, sour cream, and half of the shredded cheddar cheese. Add salt and pepper to taste. Mix until smooth and creamy. Set aside.
Cook the meats:
Heat olive oil in a skillet over medium-high heat. Season the chicken breasts and steaks with salt, pepper, and Italian seasoning.
Cook chicken for 5–6 minutes per side until fully cooked.
Cook steaks for 4–5 minutes per side for medium-rare, or longer depending on preference.
Set the cooked meat aside.
Assemble the bake:
In a baking dish, spread the mashed potatoes evenly as the bottom layer. Place the cooked chicken and steaks over the mashed potatoes.
Top with cheese:
Sprinkle the remaining cheddar cheese and Parmesan cheese over the meat. Add minced garlic over the top for added flavor.
Bake:
Place the dish in the oven and bake for 10 minutes, or until the cheese is melted and bubbly.
