Ingredients Notes

The magic of these Garlic Parmesan Steak Bites with Mashed Potatoes lies in the harmony of its ingredients. Each one plays an important role in delivering bold, savory flavors with every forkful.

The steak is the star of the show. I prefer using boneless sirloin steak because it's tender, affordable, and easy to cube into bite-sized pieces. If you happen to have ribeye or New York strip on hand, they work beautifully too, offering even more tenderness and richness.

Garlic brings its signature pungent, savory aroma that pairs perfectly with the beef. I recommend using freshly minced garlic cloves for maximum flavor. Pre-minced jarred garlic works in a pinch, but nothing beats the vibrant punch of fresh garlic.

Parmesan cheese adds a nutty, salty finish that elevates the entire dish. Use freshly grated Parmesan rather than the pre-shredded kind for the creamiest texture and best melt.

For the mashed potatoes, Yukon Gold potatoes are my go-to. They create the creamiest, most buttery mash with a naturally rich flavor. Russets can also work if you prefer a fluffier texture.

Finally, don’t forget the unsalted butter and heavy cream for the mashed potatoes. The butter adds richness while the cream makes the potatoes silky and smooth. A hand mixer or potato masher is all you’ll need for the perfect consistency.

Now that you’ve gathered your ingredients, let’s move on to how simple this dish is to prepare.

How To Make This Garlic Parmesan Steak Bites With Mashed Potatoes

Creating these flavorful Garlic Parmesan Steak Bites with Mashed Potatoes is surprisingly easy. Let me guide you through it step by step.

Start by preparing your mashed potatoes. Peel and cube your Yukon Gold potatoes, then place them in a large pot of salted water. Bring to a boil and let them simmer until fork-tender, about 15 minutes. Drain the potatoes thoroughly, returning them to the hot pot to allow any excess moisture to evaporate.

While your potatoes are boiling, cube your sirloin steak into bite-sized pieces. Pat them dry with paper towels to ensure a good sear, then season generously with salt and pepper.

Heat a large skillet over medium-high heat and add a splash of olive oil. Once shimmering, add your steak bites in a single layer. Avoid overcrowding the pan; if necessary, cook in batches to ensure each piece gets a beautiful, caramelized crust. Sear for 2-3 minutes per side, depending on your preferred doneness, then transfer to a plate and tent with foil to keep warm.

Reduce the heat to medium and add a few tablespoons of butter to the same skillet. Once melted, toss in your minced garlic and sauté for about 30 seconds until fragrant—be careful not to burn it. Return the steak bites to the pan, toss to coat in the garlic butter, then sprinkle generously with freshly grated Parmesan cheese.

By now, your potatoes should be ready for mashing. Add the butter, heavy cream, and a touch of salt. Mash until smooth and creamy, adjusting the seasoning to taste. If you like extra creamy potatoes, you can add a bit more cream or use a hand mixer for an ultra-smooth finish.

In under 40 minutes, you’ll have a plateful of tender, juicy steak bites coated in garlicky Parmesan goodness, nestled beside a heap of velvety mashed potatoes.

Storage Options

If you happen to have leftovers (which is rare in my house), they store beautifully.

For short-term storage, place the steak bites and mashed potatoes in separate airtight containers. They’ll keep in the refrigerator for up to 3 days. This separation helps maintain the best texture when reheating.

If you want to freeze portions, the mashed potatoes freeze better than the steak. Spoon the potatoes into freezer-safe containers or bags, removing as much air as possible. They can be frozen for up to 2 months. The steak bites can be frozen too, but keep in mind they may lose some tenderness after reheating.

When you're ready to reheat, gently warm the mashed potatoes on the stovetop with a splash of cream to restore their creamy texture. The steak bites can be reheated in a skillet over low heat or in the microwave at 50% power to avoid overcooking.

Variations and Substitutions

The beauty of this recipe is how easily it can be customized to suit your tastes and pantry.

For a leaner option, substitute chicken breast or turkey breast for the steak. The garlic Parmesan sauce pairs wonderfully with poultry too.

If you're craving a spicy kick, add a pinch of red pepper flakes or a dash of hot sauce to the garlic butter mixture before tossing the steak bites.

You can lighten up the mashed potatoes by using half-and-half instead of heavy cream, or even swap in Greek yogurt for a tangy, protein-rich alternative.

Vegetable lovers can stir some steamed broccoli or sautéed spinach into the mashed potatoes for added color and nutrients.

And for a low-carb version, serve the steak bites over cauliflower mash instead of traditional potatoes—it’s just as creamy and satisfying!

Don’t be afraid to experiment and make this dish your own. No matter which variation you try, you’ll end up with a comforting, crowd-pleasing meal.
