Let’s walk through this recipe step by step so you can savor every moment—from boiling potatoes to plating up those irresistible steak bites over a bed of creamy mash.
1. Begin by preparing the mashed potatoes. Place the cubed potatoes in a large pot and cover them with cold water. Add a pinch of salt and bring to a rolling boil. Cook until the potatoes are fork-tender, about 15–20 minutes, then drain and set aside.
2. While the potatoes are bubbling away, heat a large skillet over medium-high heat. Add 2 tablespoons of butter and let it foam, coating the pan.
3. Once the butter has melted and begins to sizzle, add the sirloin steak bites in a single layer. Be careful not to overcrowd the pan so each piece can brown properly. Season with salt, black pepper, and Italian seasoning, then cook until the edges are beautifully browned on all sides, approximately 3–4 minutes.
4. Add the minced garlic to the skillet and continue cooking for 1–2 minutes more. Keep the garlic moving so it releases its flavor without burning.
5. Stir in the remaining 2 tablespoons of butter, allowing it to melt completely. Toss the steak bites in the bubbling garlic butter until every piece is coated in that glossy sauce.
6. Remove the skillet from heat and immediately sprinkle the grated Parmesan cheese over the hot steak bites. Add the chopped parsley for garnish, then cover briefly to let the cheese melt into the sauce.
7. Return to your drained potatoes and add the milk (or heavy cream) along with 2 tablespoons of butter for potatoes. Use a potato masher or ricer to mash until your potatoes reach a smooth, creamy consistency. Season with salt and pepper to taste.
8. Serve the steak bites hot atop a generous scoop of mashed potatoes, letting the garlicky Parmesan butter drip down for maximum flavor impact.

Leftovers? No problem. With a few simple tricks, you can keep your Garlic Parmesan Steak Bites with Mashed Potatoes tasting just as amazing the next day. The key is to store components properly and reheat them carefully to maintain texture and flavor.
Split the steak bites and mashed potatoes into separate containers to prevent the potatoes from absorbing meat juices. They’ll stay fresh for up to 3–4 days.
Lay the steak bites in a single layer on a baking sheet and freeze until solid. Transfer to a freezer bag with as much air removed as possible. Freeze mashed potatoes in a separate bag or container. Both can last up to 2 months.
For steak bites, rewarm in a skillet over medium heat with a splash of broth or butter to revive the sauce. Mashed potatoes reheat best in a pot with a little milk or cream, stirring frequently to restore creaminess.
If you do use a microwave, heat in short intervals, stirring in between. This prevents cold spots and helps maintain a smooth texture, especially for the potatoes.
