Using fresh garlic, Parmesan cheese, and just the right blend of seasonings will elevate this dish to delicious heights without any fuss.
- 1 ½ pounds sirloin steak, cut into 1-inch cubes: Choose fresh, good-quality sirloin for tender, flavorful steak bites.
- 1 tablespoon olive oil: Helps to sear the steak to a beautiful brown crust and adds subtle fruitiness.
- 3 tablespoons unsalted butter: Adds richness to the steak bites and is essential for the garlic sauce.
- 4 garlic cloves, minced: Provides that unmistakable garlic aroma and flavor that ties the dish together.
- ½ teaspoon salt: Enhances all the flavors without overpowering them.
- ½ teaspoon black pepper: Adds a gentle kick and depth to the steak seasoning.
- ½ teaspoon smoked paprika: Brings a subtle smokiness that complements the steak perfectly.
- ¼ cup grated Parmesan cheese: Melts slightly over the hot steak bites, lending nutty, savory notes.
- 2 tablespoons chopped fresh parsley: Adds a fresh, herbaceous pop of color and flavor.
- 2 pounds Yukon gold potatoes, peeled and cubed: The creaminess of Yukon golds is ideal for smooth mashed potatoes.
- 4 tablespoons unsalted butter (for potatoes): Creates velvety richness in the mashed potatoes.
- ½ cup milk: Lightens and softens the mashed potatoes for that perfect texture.
- ¼ cup sour cream: Introduces tangy creaminess that brightens the mashed potatoes.
- Salt and pepper to taste: Essential for seasoning the potatoes to perfection.
How to Make Garlic Parmesan Steak Bites with Mashed Potatoes Recipe
Step 1: Prepare the Mashed Potatoes
Start by bringing a large pot of salted water to a rolling boil. Add the peeled and cubed Yukon gold potatoes and let them cook for about 15 to 20 minutes or until they are tender enough to pierce easily with a fork. Once done, drain the potatoes and return them to the warm pot. This helps any excess moisture evaporate for fluffier mashed potatoes. Add the butter, milk, and sour cream along with a pinch of salt and pepper, then mash everything together until smooth and creamy. Keep the pot covered to retain heat while you prepare the steak bites.
Step 2: Season and Sear the Steak Bites
While your potatoes are cooking, heat the olive oil in a large skillet over medium-high heat. Pat the steak cubes dry with paper towels—this step is critical to getting a good sear. Then season them evenly with salt, black pepper, and smoked paprika. Add the steak bites to the skillet in a single layer, making sure not to overcrowd the pan to promote even browning. Let them sear without moving for 2 to 3 minutes, then flip and sear the other sides until they reach your desired doneness. Once browned, transfer the steak bites onto a plate and set aside.
Step 3: Create the Garlic Parmesan Sauce
Reduce the skillet heat to medium, then add the butter and minced garlic. Sauté the garlic gently for 1 to 2 minutes until it becomes fragrant and golden, stirring to scrape up any delicious browned bits left from the steak. Return the steak bites to the pan and toss them in the luscious garlic butter sauce to coat every cube evenly. Finally, sprinkle the grated Parmesan cheese and fresh parsley over the steak bites, allowing the cheese to melt slightly and infuse every bite with its rich, nutty flavor.
Step 4: Plate and Serve
For the perfect presentation, serve the steaming garlic Parmesan steak bites over a generous bed of creamy mashed potatoes. The steak juices will mingle with the potatoes, ensuring every forkful is dripping with flavor. This combination is guaranteed to make your taste buds sing with joy.
How to Serve Garlic Parmesan Steak Bites with Mashed Potatoes Recipe

Garnishes
Fresh parsley is already part of the recipe and makes a perfect garnish, adding a burst of color and brightness. If you want to take it up a notch, a light grating of extra Parmesan right before serving or a thin lemon wedge on the side offers a zesty contrast that cuts through the richness beautifully.
Side Dishes
This dish is wonderfully complete on its own, but if you want to add a green element, serve it alongside steamed asparagus, roasted Brussels sprouts, or a simple arugula salad with a citrus vinaigrette. These sides add freshness and help balance the richness of the steak and potatoes.
Creative Ways to Present
Consider plating the steak bites and mashed potatoes in a shallow bowl for a comforting, rustic vibe. For a fancier touch, stack the steak bites on top of the potatoes in a neat heap and drizzle any remaining garlic butter sauce around the plate. A sprinkle of crispy fried shallots or garlic chips can add a delightful crunch that elevates the dish’s texture.
Make Ahead and Storage
Storing Leftovers
Leftover steak bites and mashed potatoes should be stored separately in airtight containers in the refrigerator. This helps maintain their individual textures and flavors, preventing sogginess.
Freezing
You can freeze the mashed potatoes successfully by placing them in a freezer-safe container, but steak bites freeze best when cooked slightly less than desired; freeze in a single layer on a baking sheet first, then transfer to a container to prevent clumping. Freeze for up to 2 months for best quality.
Reheating
When reheating, gently warm mashed potatoes on the stovetop or microwave, adding a splash of milk to restore creaminess. For steak bites, reheat over medium heat in a skillet with a little butter or olive oil to avoid drying, stirring gently until heated through.
FAQs
Can I use a different cut of steak for this recipe?
Absolutely! While sirloin is tender and budget-friendly, ribeye or New York strip steak are excellent alternatives that offer more marbling and a richer flavor, perfect for steak bites.
Is it necessary to peel the potatoes before mashing?
Peeling Yukon gold potatoes creates a smoother texture for mashed potatoes, but if you prefer a more rustic mash, leaving the skins on adds extra nutrients and a bit of texture.
How can I adjust the recipe for spicier steak bites?
Add a pinch of cayenne pepper or a dash of crushed red pepper flakes to the seasoning mix before searing the steak for a subtle heat kick without overpowering the dish.
What can I substitute for sour cream in the mashed potatoes?
If you don’t have sour cream on hand, Greek yogurt is a fantastic substitute that adds both creaminess and a pleasant tang, keeping the mashed potatoes lush and flavorful.
How do I know when the steak bites are cooked to the right doneness?
For medium-rare, cook about 2 to 3 minutes per side until the interior is pink and juicy. Use a meat thermometer for precision—130 to 135°F is ideal for medium-rare. Adjust time for your preferred doneness.
