How to Make Garlic Parmesan Chicken & Steak Bake with Cheesy Loaded Mashed Potatoes
Step 1: Prepare the Garlic Parmesan Coating
In a small bowl, stir together your olive oil, minced garlic, freshly grated Parmesan, Italian seasoning, paprika, salt, and black pepper. This zesty mix forms an irresistible crust on both the chicken and steak, infusing every bite with a burst of savory, garlicky goodness.
Step 2: Arrange and Season the Protein
Lay your chicken breasts and steaks side by side in a baking dish. Make sure they’re not overlapping so each piece can brown nicely. Using a brush (or the back of a spoon), generously slather your garlicky Parmesan mixture over every surface. Don’t be shy—every bit of this flavor-packed sauce belongs on that meat!
Step 3: Bake the Chicken & Steak
Pop the dish in a preheated oven at 400°F (200°C). Bake for 25 to 30 minutes, or just until the chicken is fully cooked (internal temp of 165°F) and the steaks are done to your liking. The irresistible aroma will fill your kitchen; you’ll know they’re ready when the tops are golden and the meat is juicy.
Step 4: Make the Cheesy Loaded Mashed Potatoes
Meanwhile, boil your peeled, cubed russet potatoes until they’re completely tender—about 15 minutes. Drain and return to the pot, then mash with butter, sour cream, and whole milk until irresistibly smooth. Fold in shredded cheddar, crumbled bacon, and scallions for a loaded mash that’s as comforting as it is craveable!
Step 5: Plate and Finish
Spoon a big, fluffy mound of loaded mashed potatoes onto each plate, then lay the gorgeous chicken and steak on top or alongside. Don’t forget a finishing shower of fresh parsley—the color and brightness make the dish pop! Serve right away for the dreamiest Garlic Parmesan Chicken & Steak Bake with Cheesy Loaded Mashed Potatoes experience.

Garnishes
Don’t skip the finishing touches! A sprinkle of chopped parsley brings a vibrant freshness that lifts the entire plate, and more crumbled bacon or an extra pinch of shaved Parmesan is always welcome. These simple garnishes make each serving of Garlic Parmesan Chicken & Steak Bake with Cheesy Loaded Mashed Potatoes look as inviting as it tastes.
Side Dishes
This meal is hearty enough to stand alone, but for a truly memorable spread, consider some tender green beans, crisp roasted asparagus, or a bright, lemony salad. Light veggies add color and a fresh contrast to the rich, comforting main.
Creative Ways to Present
For family-style serve-up, arrange the chicken, steak, and mashed potatoes on a large platter and let everyone dig in! Or, plate individually with chicken and steak fanned over the potatoes, finishing each plate with parsley and a little bacon. For a rustic flair, serve in oven-to-table baking dishes; it’s casual yet totally special.
Make Ahead and Storage
Storing Leftovers
Got leftovers (lucky you)? Transfer any extra Garlic Parmesan Chicken & Steak Bake with Cheesy Loaded Mashed Potatoes to airtight containers and keep them in the fridge for up to 3 days. The flavors actually deepen overnight, making your next meal even more delicious!
Freezing
Both the protein and the loaded mashed potatoes freeze surprisingly well. Cool everything completely, then wrap or seal tightly before freezing for up to 1 month. Thaw in the refrigerator overnight so the textures stay tender and creamy.
Reheating
To reheat, place portions in a baking dish, cover with foil, and warm in a 350°F oven until heated through—about 20 minutes. For a quick fix, individual servings can also be microwaved. Add a splash of milk to the potatoes if needed for extra creaminess.
FAQs
Can I use different cuts of steak or chicken?
Absolutely! While ribeye and sirloin are delicious, you can swap in strip steak, filet, or even boneless thighs. Just adjust cooking times as needed to keep everything juicy and flavorful.
How do I make this dish gluten-free?
The Garlic Parmesan Chicken & Steak Bake with Cheesy Loaded Mashed Potatoes is naturally gluten-free as long as all ingredients (especially bacon and seasonings) are certified GF. Double-check labels if you’re sensitive!
What’s the best way to tell when the meats are done?
Use an instant-read thermometer for best results—chicken should hit 165°F, and steaks can be cooked anywhere from medium-rare (130°F) to well done (160°F), depending on your preference.
Can I prepare the mashed potatoes in advance?
Yes! The loaded mashed potatoes can be made up to a day early—just reheat gently with a splash of milk and give it a good stir before serving.
What’s the secret to extra-creamy potatoes?
For dreamy, pillowy mashed potatoes, always mash them while hot and don’t skimp on the butter, sour cream, and milk. Stir in the cheese, bacon, and green onions last, so everything stays fluffy and melty!
