Ingredients Notes

This recipe keeps it simple with a handful of well-chosen ingredients that each play a critical role in the final dish.

Steak is the star of the show. I usually go for sirloin—it’s affordable, tender, and cooks quickly. If you prefer something even richer, ribeye or New York strip work beautifully too. Just be sure to cut the meat into evenly sized bites so they sear properly.

Garlic brings the signature punch to these steak bites. Fresh minced garlic is best here—you’ll want 4 to 5 cloves. It infuses the butter and steak with deep, aromatic flavor that makes the whole dish sing.

Parmesan cheese takes things to the next level. Go for freshly grated Parmesan, not the pre-shredded kind. It melts more evenly and gives you that nutty, salty finish that makes each bite irresistible.

Potatoes form the creamy base. I recommend using Yukon Golds or Russets, as they mash beautifully. Add butter, cream, and a touch of garlic to make them smooth, rich, and flavorful enough to stand on their own—but even better under those steak bites.

You’ll also want unsalted butter, olive oil, heavy cream, salt and pepper, and a sprinkle of parsley for garnish. No fancy tools required—just a good skillet, a large pot for boiling potatoes, and a potato masher or hand mixer.

How To Make This Garlic Parmesan Steak Bites With Mashed Potatoes

Creating this comfort-packed dish is easier than you think. Here's how to bring it all together step by step.

Start by prepping your potatoes. Peel and chop them into evenly sized chunks and get them boiling in salted water. Let them simmer until fork-tender—about 15 minutes—while you work on the steak.

Next, pat your steak pieces dry with paper towels. This is key to getting a nice sear. Heat a large skillet over medium-high and add a tablespoon each of butter and olive oil. Once the butter is melted and bubbling, add your steak in a single layer. Let them sear undisturbed for 2-3 minutes before flipping.

Once the steak is browned on all sides and just cooked through, remove it to a plate. In the same skillet, reduce the heat to medium and add your minced garlic. Stir constantly for about 30 seconds until fragrant—careful not to let it burn!

Add the steak bites back to the pan along with the rest of the butter and stir to coat everything in that rich garlic butter. Finish with a generous handful of grated Parmesan cheese, tossing until it melts and clings to the meat.

Meanwhile, drain your tender potatoes and return them to the pot. Add butter, cream, salt, and a pinch of garlic powder if desired. Mash until smooth and creamy. Taste and adjust for seasoning.

Spoon a hearty mound of mashed potatoes onto each plate, then pile on the steak bites. Finish with a sprinkle of parsley and a little extra Parmesan for good measure.

From start to finish, this recipe takes about 30–35 minutes—and every second is worth it.

Storage Options

If you have leftovers (which is rare in my house!), they store beautifully for another meal.

Refrigerate any extra steak bites and mashed potatoes in separate airtight containers. They’ll keep well in the fridge for up to 3 days.

For longer storage, you can freeze the mashed potatoes, though the texture may change slightly after thawing. Let them cool completely, then transfer to a freezer-safe bag or container. Freeze for up to 1 month.

Reheating is simple: warm the steak bites in a skillet over medium heat with a splash of beef broth or butter to keep them moist. Reheat the mashed potatoes on the stovetop or in the microwave, stirring in a bit of cream or milk to restore their smoothness.

Variations and Substitutions

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

If you're not a fan of red meat, chicken breast or thighs make a great substitute. Cube them up and follow the same method—you’ll still get plenty of garlicky, cheesy goodness.

Want to lighten things up? Try cauliflower mash instead of traditional potatoes. It cuts carbs without sacrificing that creamy texture we all love.

Add some veggies into the mix! A quick sauté of zucchini, mushrooms, or asparagus in the same garlic butter pan adds extra flavor and color.

Craving spice? A pinch of red pepper flakes or a dash of hot sauce in the garlic butter gives the dish a subtle kick.

You can even make it keto-friendly by skipping the mashed potatoes and serving the steak bites over zoodles or sautéed spinach. It’s still rich, satisfying, and full of flavor.

The best part about this recipe is how forgiving it is. No matter what you swap in or out, you’ll still end up with a dish that’s cozy, comforting, and totally delicious. Don’t be afraid to experiment—you might just stumble on your own new favorite version.
