How to Make Garlic Parmesan Chicken & Steak Bake with Cheesy Loaded Mashed Potatoes Recipe
Step 1: Prep and Season the Meats
Start by cubing your chicken breasts and ribeye steaks into bite-sized pieces. Toss them in a bowl with olive oil, minced garlic, grated Parmesan, Italian seasoning, paprika, salt, and pepper. This simple marinade lets each cube soak in the flavorful blend that will make every morsel pop. Set this aside while you prepare the potatoes.
Step 2: Boil and Mash Potatoes
Place the peeled and cubed russet potatoes in a large pot of salted water and bring to a boil. Cook until tender, about 15–20 minutes. Drain well, then add butter, sour cream, and milk, mashing everything until smooth and creamy. Stir in shredded cheddar cheese, bacon bits, and chopped green onions, seasoning with salt and pepper to taste. These cheesy loaded mashed potatoes are what comfort food dreams are made of.
Step 3: Sear the Meat Cubes
Heat a large skillet over medium-high heat and add a little olive oil if needed. Sear the seasoned chicken and steak cubes in batches until they develop a beautiful golden crust on all sides but remain juicy inside. This step locks in flavor and texture before baking.
Step 4: Assemble and Bake
In a baking dish, layer the seared chicken and steak evenly. Spoon the cheesy loaded mashed potatoes over the top, spreading them out to cover the meat completely. Bake in a preheated oven at 375°F (190°C) for 15–20 minutes until everything is heated through and the top has just started to turn golden and bubbly.
How to Serve Garlic Parmesan Chicken & Steak Bake with Cheesy Loaded Mashed Potatoes Recipe

Garnishes
Sprinkle freshly chopped parsley over the bake right before serving for a pop of color and fresh herbal aroma that balances the rich dish beautifully. You can also add a little extra grated Parmesan or cracked black pepper for that finishing touch.
Side Dishes
This bake is a hearty meal on its own, but pairing it with a crisp green salad or steamed seasonal vegetables like broccoli or green beans adds brightness and crunch to your plate. These sides help lighten up the richness while complementing the flavors wonderfully.
Creative Ways to Present
For a fun twist, serve the Garlic Parmesan Chicken & Steak Bake with Cheesy Loaded Mashed Potatoes Recipe in individual ramekins or small cast-iron skillets. This not only looks charming but makes portion control easier for family dinners or entertaining guests. Alternatively, arrange it over a bed of roasted asparagus or baby spinach for a colorful, gourmet presentation.
Make Ahead and Storage
Storing Leftovers
Once cooled, transfer any leftovers to an airtight container and refrigerate for up to 3 days. The flavors deepen wonderfully overnight, making the next-day meal just as delightful.
Freezing
You can freeze portions of this bake for up to 2 months. Use freezer-safe containers and thaw overnight in the refrigerator before reheating. The mashed potatoes might thicken upon freezing; just add a splash of milk when reheating to restore creaminess.
Reheating
To reheat, warm leftovers in the oven at 350°F (175°C) until heated through, about 15–20 minutes. Alternatively, use a microwave on medium power to prevent drying out, stirring halfway through to keep it evenly warm and super creamy.
FAQs
Can I use other cuts of steak?
Absolutely! While ribeye gives great marbling and tenderness, sirloin or strip steak can also work well if you prefer leaner options. Just be mindful to not overcook them during searing to keep them juicy.
Is this recipe suitable for meal prep?
Yes, it holds up beautifully as a meal prep option. The flavors stay vibrant after storing, and reheating is easy. Just pack it in single portions for quick lunches or dinners throughout the week.
Can I make this dish gluten-free?
Definitely! This recipe is naturally gluten-free as long as you double-check that your bacon bits and seasonings do not contain any hidden gluten ingredients.
What can I substitute for sour cream in the mashed potatoes?
If you don’t have sour cream on hand, Greek yogurt is a great substitute that adds similar creaminess and tang. Just use the same amount as sour cream for best results.
How do I get the best garlic flavor without overpowering the dish?
Mincing fresh garlic and cooking it gently with the meats allows the flavor to mellow and infuse the dish smoothly. Avoid adding raw garlic too late, which can sometimes be too sharp or harsh.

- 1/4 cup cooked bacon bits
- 1/4 cup green onions, chopped

Instructions
- Preheat the oven: Preheat your oven to 400°F (200°C) to prepare for baking the meat and finishing the potatoes.
- Prepare the meat: In a large bowl, combine cubed chicken breasts and ribeye steaks with olive oil, minced garlic, grated Parmesan cheese, Italian seasoning, paprika, salt, and pepper. Toss well to ensure all pieces are evenly coated.
- Bake the meat: Spread the seasoned chicken and steak pieces on a baking sheet in a single layer. Bake in the preheated oven for 20-25 minutes, or until the meat is cooked through and slightly browned.
- Cook the potatoes: While the meat bakes, place the peeled and cubed russet potatoes in a large pot. Cover with cold water and add a pinch of salt. Bring to a boil over medium-high heat and cook until potatoes are tender when pierced with a fork, about 15 minutes.

Notes
- For a spicier version, add a pinch of crushed red pepper flakes to the meat seasoning mix.
- Use Greek yogurt instead of sour cream for a lighter, tangier mashed potato.
- Ensure the steak and chicken are cut into uniform cubes for even cooking.
- You can prepare the mashed potatoes a few hours ahead and reheat gently before serving.
- Fresh parsley garnish adds a nice herbal freshness but can be skipped if unavailable.
