Ingredients Notes

The beauty of Garlic Parmesan Steak Bites With Mashed Potatoes lies in its simple, well-balanced ingredients. Each element contributes to the dish’s irresistible flavor and satisfying texture.

The steak is the star of the show. I recommend using sirloin steak for its perfect balance of tenderness and affordability. Cut it into evenly-sized cubes, about one inch, so they cook quickly and evenly while staying juicy inside. Ribeye or New York strip also work wonderfully if you want to splurge.

Next comes the garlic — lots of it! Freshly minced garlic is essential here. As it sautés in the butter, it releases its rich aroma and deepens the flavor profile, giving the steak bites their signature taste.

The parmesan cheese adds a nutty, salty richness that perfectly complements the garlicky butter sauce. Use freshly grated parmesan if possible — it melts better and has a superior flavor compared to pre-shredded varieties.

For the mashed potatoes, I prefer using Yukon Gold potatoes. They’re naturally buttery and creamy, which means you can use less butter and still achieve a rich texture. Boil them until fork-tender and whip them with butter, cream, and a touch of salt for the ultimate side dish.

Finally, you’ll need a large skillet or cast-iron pan for searing the steak bites. A good, heavy pan helps achieve that beautiful golden-brown crust while locking in the juices. You’ll also need a medium pot for boiling your potatoes.

How To Make This Garlic Parmesan Steak Bites With Mashed Potatoes

Creating this comforting meal is easier than you might think. Let’s walk through the process step by step so you can serve up steakhouse flavors from your own kitchen.

Start by preparing the mashed potatoes. Peel and chop the Yukon Gold potatoes into even chunks to ensure they cook uniformly. Place them in a pot of salted water, bring it to a boil, and let them cook for about 15 minutes or until fork-tender.

While the potatoes are boiling, prep your steak. Pat the steak cubes dry with paper towels — this is key to getting a good sear. Season generously with salt, pepper, and a touch of smoked paprika if you like a hint of extra flavor.

Heat your large skillet over medium-high heat and add a bit of oil. Once the oil is shimmering, add the steak cubes in a single layer. Avoid overcrowding the pan; work in batches if necessary. Let the steak bites sear undisturbed for about 2-3 minutes per side to develop that golden-brown crust.

Once all the steak bites are cooked, reduce the heat and add butter to the pan along with the minced garlic. Stir constantly, letting the garlic cook for about 30 seconds until fragrant. Return the steak bites to the pan and toss them in the garlic butter, then sprinkle the grated parmesan over the top and stir until everything is coated in the rich, creamy sauce.

By now, your potatoes should be ready. Drain them and return them to the pot. Add butter, warm cream, and a pinch of salt, then mash until smooth and creamy. Adjust the consistency to your liking by adding more cream if necessary.

Altogether, the entire cooking process should take about 35-40 minutes. What you’ll end up with is a restaurant-quality meal that’s rich, savory, and incredibly satisfying.

Storage Options

Leftovers store wonderfully, making this recipe great for meal prep or next-day lunches.

For short-term storage, place any leftover steak bites and mashed potatoes in airtight containers. They’ll stay fresh in the refrigerator for up to 3 days.

If you want to freeze the mashed potatoes, let them cool completely and store them in a freezer-safe container for up to 2 months. The steak bites can be frozen too, though the texture may change slightly upon reheating.

When reheating, gently warm the steak bites in a skillet over low heat with a splash of broth or water to prevent them from drying out. The mashed potatoes can be reheated in the microwave or on the stovetop with a bit of cream stirred in to bring back their creaminess.

Variations and Substitutions

The flexibility of this recipe means you can easily tailor it to suit your taste or what you have on hand.

For a spicier kick, add a pinch of red pepper flakes or a dash of hot sauce to the garlic butter sauce. It gives the steak bites a nice heat that balances beautifully with the parmesan.

You can also switch up the protein. Chicken breast, shrimp, or even tofu can stand in for steak if you're looking for something different or accommodating dietary preferences.

If you're watching your dairy intake, substitute the butter with plant-based margarine and use a dairy-free parmesan alternative. The mashed potatoes can also be made with olive oil and almond milk for a lighter, dairy-free version.

Adding vegetables is another great way to make this meal even more nutritious. Toss in some sautéed mushrooms, steamed broccoli, or roasted asparagus alongside your steak bites for a colorful, balanced plate.

Don’t be afraid to experiment with different herbs and seasonings. Fresh rosemary, thyme, or a sprinkle of Italian seasoning can bring an extra layer of flavor to the dish.

Have fun making this recipe your own — it’s nearly foolproof and always delicious!
