How to Make Garlic Parmesan Chicken & Steak Bake with Cheesy Loaded Mashed Potatoes

Step 1: Prepare the Potatoes

1. Peel and chop the russet potatoes into even chunks. Place them in a large pot of salted water and bring to a boil. Cook for about 15-20 minutes or until fork-tender.
2. Drain the potatoes and return them to the pot. Add butter, sour cream, milk, cheddar cheese, salt, and pepper. Mash until smooth and creamy. Cover and set aside.

Step 2: Cook the Chicken and Steak

1. Preheat your oven to 400°F (200°C).
2. Heat 1 tablespoon of olive oil in a large skillet over medium-high heat. Season the chicken breasts with paprika, salt, and pepper, then sear for 2-3 minutes per side until golden. Remove and set aside.
3. Add another tablespoon of olive oil to the same skillet. Season the steaks with salt, pepper, and paprika. Sear for 2-3 minutes per side for a nice crust (they’ll finish cooking in the oven). Remove and set aside.

Step 3: Make the Garlic Parmesan Sauce

1. In the same skillet, reduce the heat to medium and add minced garlic. Sauté until fragrant, about 1 minute.
2. Stir in heavy cream and grated Parmesan cheese, whisking until smooth and creamy. Let it simmer for 2-3 minutes until slightly thickened. Season with salt and pepper to taste.

Step 4: Assemble the Dish

1. Spread the mashed potatoes evenly in a large baking dish. Arrange the seared chicken and steak over the potatoes.
2. Pour the garlic Parmesan sauce over the top, ensuring the chicken and steak are well-coated.
3. Sprinkle shredded mozzarella cheese generously over the dish.

Step 5: Bake and Serve

1. Bake in the preheated oven for 10-15 minutes, or until the cheese is bubbly and golden.
2. Remove from the oven, garnish with chopped chives if desired, and serve warm.

This dish is as delightful to prepare as it is to eat!

Cooking Time and Tips for Garlic Parmesan Chicken & Steak Bake with Cheesy Loaded Mashed Potatoes

How Long to Bake the Dish

Baking ensures all the flavors meld together perfectly while the cheese melts into a golden, bubbly topping. Here’s a guideline for the perfect bake:

• Chicken and Steak – After searing, bake the dish for 10-15 minutes at 400°F (200°C). The steak should reach your preferred doneness (use a meat thermometer to check), and the chicken should have an internal temperature of 165°F (74°C).

Storing and Reheating Leftovers

This dish is just as delicious the next day! Here’s how to store and reheat it:

• Refrigerator – Place leftovers in an airtight container and refrigerate for up to 3 days.
• Reheating – Reheat individual portions in the microwave or place the entire dish in the oven at 350°F (175°C) for 10-15 minutes, until warmed through.
• Freezer – You can freeze the dish for up to 1 month, though the texture of the mashed potatoes may change slightly. Wrap tightly in plastic wrap and foil, and thaw overnight in the fridge before reheating.

Tips for the Best Results

Here are some tips to elevate your Garlic Parmesan Chicken & Steak Bake to the next level:

1. Choose the Right Cuts – Use well-marbled steak (like ribeye) for maximum flavor and juicy, fresh chicken breasts for tenderness.
2. Don’t Overcook the Steak – Searing creates a crust, but it’s important not to overcook it in the oven. Use a thermometer to achieve your desired level of doneness (e.g., 130°F for medium-rare).
3. Enhance the Sauce – For an extra layer of flavor, add a splash of white wine or chicken broth while making the garlic Parmesan sauce.
4. Customize the Cheese – Swap mozzarella with provolone or Gruyère for a slightly different flavor profile.
5. Add Texture – Sprinkle crispy bacon bits or toasted breadcrumbs over the cheese layer before baking for added crunch.

This dish is as versatile as it is indulgent, making it perfect for both cozy nights in or entertaining guests!
