Ingredients Notes

The magic of these Garlic Parmesan Steak Bites lies in the flavorful, straightforward ingredients. With each component playing a key role, it's the kind of recipe where less truly is more.

The steak is the star of the show. I typically go for sirloin, as it's affordable, lean, and tender when cooked quickly over high heat. You can also use ribeye or strip steak if you're feeling fancy, but sirloin provides the perfect balance of quality and cost.

Fresh garlic is non-negotiable here. We’re not just tossing in a clove or two — this recipe leans into bold garlic flavor. Mince it finely or use a garlic press for best results. If you love garlic, feel free to add even more than the recipe calls for.

Butter and olive oil create the luscious base for the pan sauce. The butter adds richness, while the olive oil prevents it from burning during high-heat cooking. Combined, they coat the steak bites and garlic in a golden, flavorful glaze.

Parmesan cheese, freshly grated, finishes the steak bites with a nutty, savory touch. Don’t skimp on quality here — skip the pre-grated stuff and grab a wedge of Parmigiano-Reggiano if you can.

Yukon Gold potatoes are my pick for the mashed potatoes. They mash up creamy and smooth without needing too much butter or cream. Add a splash of warm milk, a dollop of sour cream, and a generous pinch of salt, and you're in mashed potato heaven.

No special equipment is required, but a cast iron skillet works wonders for searing the steak and achieving that crusty, caramelized exterior. A hand mixer or potato masher makes quick work of the mash.

How To Make This Garlic Parmesan Steak Bites With Mashed Potatoes

Creating this dish is surprisingly straightforward — and most of it happens in a single pan. Here’s how to make it happen.

Start by prepping your steak. Cut the meat into bite-sized cubes, around 1-inch each, and pat them dry with paper towels. This step helps the steak brown properly. Season generously with salt, pepper, and a touch of paprika for color and subtle smokiness.

Next, get those mashed potatoes going. Peel and chop your Yukon Golds into chunks and add them to a pot of salted boiling water. Let them cook until fork-tender, about 12-15 minutes. Drain well and return to the pot. Mash with butter, warm milk, sour cream, and salt until smooth and fluffy.

While the potatoes cook, heat your skillet over medium-high heat and add a splash of olive oil. When the oil is shimmering, add the steak in a single layer. Don’t overcrowd the pan — work in batches if needed. Let them sear undisturbed for 2-3 minutes per side until deeply browned.

Once all the steak bites are seared, return them to the skillet and reduce the heat. Add butter and your minced garlic. Stir constantly for about 1 minute, just until the garlic is fragrant and golden. Off the heat, sprinkle in the freshly grated Parmesan and toss to coat.

To serve, scoop a generous portion of mashed potatoes onto each plate and top with the sizzling garlic parmesan steak bites. Spoon over any extra garlic butter from the pan for maximum flavor.

The whole process takes about 30 minutes, start to finish. Expect a comforting, restaurant-worthy dish with minimal cleanup.

Storage Options

Leftovers store surprisingly well, making this a great make-ahead option for busy weeks.

Store any leftover steak bites and mashed potatoes in separate airtight containers. They'll keep in the refrigerator for up to 3 days.

To freeze, portion the mashed potatoes and steak bites separately into freezer-safe containers. Label and date them, and store for up to 2 months. Thaw overnight in the fridge before reheating.

Reheat the steak bites in a skillet over medium heat with a splash of broth or butter to keep them moist. For the mashed potatoes, microwave in 30-second intervals, stirring between, or reheat on the stovetop with a little milk to restore creaminess.

Variations and Substitutions

This recipe is endlessly adaptable, so don’t be afraid to make it your own.

If you’re cutting back on red meat, swap the steak for chicken breast or thighs. Cook the same way — quick sear, garlic butter, Parmesan — and you’ll still end up with a delicious meal.

Want to lower the carbs? Try cauliflower mash instead of traditional mashed potatoes. Steam or boil cauliflower florets, then blend with butter, garlic, and cream until smooth.

Feeling spicy? Add a pinch of crushed red pepper flakes or a drizzle of hot sauce to the garlic butter. It adds a subtle kick that pairs beautifully with the creamy mash.

Herb lovers can mix things up with fresh rosemary, thyme, or parsley. Stir chopped herbs into the garlic butter or sprinkle over the finished dish for an aromatic twist.

Don’t have Parmesan? Try grated Asiago or Pecorino Romano for a slightly different cheesy finish. Each brings a unique salty tang that complements the garlicky steak perfectly.

Once you’ve made this dish a few times, you’ll find yourself tweaking and personalizing it to suit your cravings. And that’s the beauty of a recipe like this — it’s a foundation for creativity and comfort all in one.
