Ingredients Notes

The magic of this dish lies in a handful of simple ingredients, each one adding depth and richness to the final plate. It’s a perfect reminder that when cooked well, everyday staples can feel downright decadent.

Let’s start with the steak. I recommend sirloin for its balance of tenderness and affordability, but ribeye or even strip steak work beautifully too. You’ll want to cut the meat into bite-sized cubes for fast, even cooking and maximum flavor in every mouthful.

Next up is the garlic – and don’t be shy. Fresh minced garlic is key here, sautéed in butter until golden and fragrant. It forms the base of the sauce and clings to the steak for an irresistible flavor punch.

Speaking of sauce, Parmesan cheese adds a salty, nutty richness that coats the steak bites and brings everything together. Go for freshly grated if you can – it melts better and adds a more authentic flavor than the pre-shredded stuff.

The mashed potatoes are the creamy anchor of this dish. I like to use Yukon Golds for their naturally buttery texture. Boil them until fork-tender, then mash with butter, warm milk, and a touch of salt. They should be smooth and rich but still light and fluffy.

As for special equipment, a heavy-bottomed skillet or cast-iron pan works best to get that signature sear on the steak. And a good potato masher or ricer helps ensure creamy potatoes without any lumps.

How To Make This Garlic Parmesan Steak Bites With Mashed Potatoes

Making this dish is much easier than it sounds – you’ll be shocked at how quickly it all comes together. Let’s take it step-by-step so everything hits the plate piping hot and perfectly seasoned.

Start by prepping your potatoes. Peel and chop them into even chunks, then drop them into a pot of salted water. Bring to a boil and cook until fork-tender – this usually takes about 15-18 minutes, giving you the perfect window to cook your steak.

While the potatoes are cooking, turn your attention to the steak. Pat your pieces dry with a paper towel – this is important for getting a good sear. Heat a generous amount of oil in a skillet over high heat until it’s just starting to smoke. Then, in batches, sear the steak bites on all sides until they develop a golden crust. Don’t overcrowd the pan or they’ll steam instead of sear.

Once the steak is cooked to your desired doneness, remove it from the pan and set it aside. In the same skillet, lower the heat and add a few tablespoons of butter, followed by your minced garlic. Stir constantly – garlic can burn quickly – and let it cook just until fragrant and golden.

Return the steak bites to the pan, toss them in the garlic butter, and sprinkle in the Parmesan cheese. Stir everything together until the cheese is melted and coats the steak. You can even turn the heat off at this point – the residual heat will help melt the cheese without overcooking the meat.

Meanwhile, drain your boiled potatoes and return them to the warm pot. Add in your butter, warm milk, and salt. Mash until smooth and creamy, adjusting the texture with more milk if needed. Taste and season with more salt or a dash of pepper to your liking.

From start to finish, this recipe takes about 35 to 45 minutes – most of it hands-on. When you’re done, you’ll have a sizzling skillet of garlicky steak bites and a bowl of creamy mashed potatoes ready to serve.

Storage Options

If you have leftovers, you’re in luck – this dish reheats well and makes an excellent lunch the next day.

Store the steak bites and mashed potatoes separately in airtight containers. This helps keep the textures intact and prevents the steak from getting too soggy. Both can be kept in the refrigerator for up to 3-4 days.

For longer storage, you can freeze the mashed potatoes in freezer-safe bags or containers for up to 2 months. While the steak can be frozen too, it’s best enjoyed fresh since reheating can dry it out.

To reheat, warm the mashed potatoes in the microwave with a splash of milk to restore creaminess. The steak can be reheated in a skillet over low heat with a bit of butter or oil to prevent overcooking. Avoid the microwave for the steak if possible – it tends to toughen.

Variations and Substitutions

One of the best things about this recipe is how easy it is to adapt based on what you have or your dietary preferences.

Want a low-carb version? Swap out the mashed potatoes for cauliflower mash. It still gives you that creamy, fluffy texture but with fewer carbs and a slightly nutty flavor that pairs well with the steak.

If you’re out of Parmesan, try using pecorino Romano or even a sharp aged cheddar. Each cheese brings its own unique flair, so don’t be afraid to experiment.

Prefer a leaner protein? This same method works great with chicken breast or pork tenderloin cut into cubes. Just adjust the cooking time to avoid drying out the meat.

You can also add in veggies to stretch the dish a bit further. Try tossing in sautéed mushrooms, green beans, or even spinach with the steak for an extra boost of flavor and nutrition.

Don’t be afraid to play with the seasoning either. Add a pinch of red pepper flakes for heat, or finish the steak with a splash of balsamic glaze for a tangy twist.

This Garlic Parmesan Steak Bites with Mashed Potatoes recipe is one of those meals that invites creativity. Once you’ve nailed the basics, feel free to make it your own. Whether you stick to the classic version or try something new, it’s bound to be a hit.
