Ingredients You’ll Need
Every ingredient in this Garlic Parmesan Steak Bites with Mashed Potatoes Recipe plays a vital role in creating a symphony of flavors and textures. From the savory steak to the creamy potatoes, these simple staples come together to deliver a dish that is anything but ordinary.
- 1 pound steak (such as sirloin): Choose a tender cut for juicy bite-sized pieces packed with flavor.
- 2 tablespoons olive oil: Helps sear the steak to a golden perfection while adding subtle fruitiness.
- 4 cloves garlic, minced: Infuses the steak bites with an irresistible aroma and depth.
- 1 tablespoon butter: Adds richness to the steak and helps meld all the seasonings together.
- 1/2 teaspoon garlic powder: Boosts the garlicky taste without overpowering.
- 1/4 teaspoon onion powder: Adds a subtle sweet and savory lift to the seasoning mix.
- 1/2 cup grated Parmesan cheese: Brings a nutty, salty finish that clings beautifully to each steak bite.
- Salt and pepper, to taste: Essential for balancing and enhancing all the flavors.
- 4 large potatoes, peeled and diced: The base for fluffy mashed potatoes—choose starchy potatoes like Russets for the best texture.
- 1/4 cup heavy cream: Makes the mashed potatoes luxuriously smooth and creamy.
- 1/4 cup milk: Lightens the mashed potatoes just right and keeps them from getting too dense.

How to Make Garlic Parmesan Steak Bites with Mashed Potatoes Recipe
Step 1: Sear the Steak Bites
Start by heating the olive oil in a large skillet over medium-high heat. Once hot, add the steak bites in a single layer and let them cook undisturbed for a couple of minutes to build a nice crust. Stir occasionally and cook for a total of 4-6 minutes until all sides are beautifully browned. This searing step locks in the juices that make these steak bites so tender and flavorful.
Step 2: Add the Garlic
Next, toss the minced garlic into the skillet with the seared steak bites. Cook everything together for about one minute, stirring constantly, until you can smell the garlic’s intoxicating fragrance. Be careful not to burn the garlic as it can turn bitter. This brief cooking releases its full aromatic potential, setting the stage for the cheesy sauce to come.
Step 3: Build the Parmesan Garlic Sauce
Now, stir in the butter, garlic powder, onion powder, and grated Parmesan cheese with a pinch of salt and pepper. The butter melts to create a velvety base while the Parmesan clings to each steak bite, melting into a gooey, flavorful coating. Let this cook for 2 more minutes so the flavors blend seamlessly. You’re basically creating a rich, luxurious sauce that turns simple steak bites into a standout dish.
Step 4: Boil the Potatoes
While your steak bites are sizzling away, bring a large pot of salted water to a boil and add the diced potatoes. Cook for about 10-12 minutes, or until the potatoes are fork-tender. Properly boiled potatoes are the secret to creamy mashed potatoes, so don’t rush this step. Drain them thoroughly before moving on.
Step 5: Mash the Potatoes
Return the drained potatoes to the pot and begin mashing while adding the heavy cream, milk, and butter. This combination creates irresistibly smooth and creamy mashed potatoes. Season with salt and pepper to your liking. The rich texture perfectly complements the savory steak bites and creates a well-rounded plate.
Step 6: Plate and Enjoy
Dish out a generous scoop of mashed potatoes onto each plate, then pile the warm Garlic Parmesan Steak Bites right on top. The melting cheese and buttery garlic sauce over the creamy potatoes make every bite a delightful experience. Serve immediately and savor this hearty, comforting meal that feels like a warm hug on a plate.
How to Serve Garlic Parmesan Steak Bites with Mashed Potatoes Recipe

Garnishes
A sprinkle of freshly chopped parsley or chives adds a vibrant pop of color and a hint of freshness that cuts through the rich flavors in this dish. You can also add a light dusting of extra grated Parmesan for an even cheesier experience. These small touches elevate the plate’s visual appeal and brightness.
Side Dishes
While the steak bites and mashed potatoes shine on their own, some crisp steamed green beans or a simple mixed green salad with a tangy vinaigrette create balance by introducing freshness and crunch. Roasted Brussels sprouts or garlic butter asparagus also pair beautifully if you want to amp up the veggie factor.
Creative Ways to Present
For a family-style feast, serve the steak bites in a rustic cast-iron skillet placed right on the table, surrounded by bowls of mashed potatoes and fresh sides. Alternatively, try spooning the steak bites artistically atop a smooth bed of mashed potatoes on individual plates for a restaurant-worthy presentation. Either way, this dish impresses with both flavor and style.
Make Ahead and Storage
Storing Leftovers
To keep your Garlic Parmesan Steak Bites with Mashed Potatoes Recipe tasting fresh, store leftovers in airtight containers in the refrigerator for up to 3 days. Separate the steak bites and mashed potatoes for best results, so nothing gets soggy or overly soft.
Freezing
If you want to save some for later, this dish freezes well. Place the steak bites and mashed potatoes in separate freezer-safe containers and freeze for up to 2 months. Labeling your containers helps avoid mystery meals later!
Reheating
Reheat steak bites gently in a skillet over medium-low heat to maintain their tenderness and prevent them from drying out. Warm the mashed potatoes in the microwave or on the stove, adding a splash of milk or cream if needed to loosen them up. Stir frequently to heat evenly and keep the creamy texture.
FAQs
Can I use other cuts of steak for this recipe?
Absolutely! Sirloin is a popular choice for its tenderness and flavor, but you can use ribeye, flank, or even filet mignon if you prefer. Just make sure to cut the steak into bite-sized pieces for even cooking.
Is it possible to make this recipe gluten-free?
Yes, this Garlic Parmesan Steak Bites with Mashed Potatoes Recipe is naturally gluten-free as long as you use pure Parmesan cheese and unseasoned butter and cream. Always double-check your ingredients to be certain.
Can I substitute Parmesan cheese with another type of cheese?
Parmesan provides a distinctive nutty, salty flavor and helps create that luscious sauce. However, Pecorino Romano or Asiago can be used as substitutes for a slightly different, yet delicious twist.
How can I make my mashed potatoes extra creamy?
For ultra-creamy mashed potatoes, use starchy potatoes like Russets, warm your cream and milk before adding, and mash while the potatoes are hot. Adding butter early also helps create a rich texture.
What can I do if I don’t have heavy cream?
If you don’t have heavy cream, you can substitute with an equal amount of whole milk mixed with a tablespoon of melted butter. This combination mimics the richness of cream and still keeps the mashed potatoes smooth.
