Ingredients You’ll Need
The magic of Garlic Butter Steak Bites and Mash lies in its simplicity—each ingredient is carefully chosen to build layers of flavor and texture. Don’t skip on the details: every element, from the choice of steak to the creamy tang of sour cream in the mash, plays a starring role.
- Sirloin or Ribeye Steak (1 ½ lbs, cut into 1-inch cubes): Choose a well-marbled steak for melt-in-your-mouth tenderness and rich, beefy flavor.
- Olive Oil (1 tablespoon): A light coating helps achieve that irresistible sear without burning the butter.
- Unsalted Butter (4 tablespoons for steak, 4 tablespoons for mash): Butter is the soul of both the steak bites and the mash, giving luscious richness and a glossy finish.
- Garlic (4 cloves, minced): Don’t hold back! Fresh garlic infuses the steak bites with robust, aromatic flavor.
- Chopped Fresh Parsley (1 tablespoon): Brightens up the dish with color and a fresh pop of taste.
- Salt and Black Pepper (to taste): Season generously to bring out all the best flavors in both steak and potatoes.
- Yukon Gold or Russet Potatoes (2 lbs, peeled and cubed): These varieties create the perfect creamy mash—Yukon Golds for buttery flavor, russets for fluffiness.
- Whole Milk (½ cup, warmed): Warm milk blends more smoothly, ensuring your mash stays light and creamy.
- Sour Cream (¼ cup): Adds a subtle tang and silkiness to the potatoes that elevates them above the ordinary.
How to Make Garlic Butter Steak Bites and Mash
Step 1: Boil and Mash the Potatoes
Start with the foundation: creamy, dreamy mashed potatoes. Place your peeled and cubed potatoes in a large pot and cover them with cold water, adding a generous pinch of salt. Bring to a boil and cook for 15 to 20 minutes, or until the potatoes are fork-tender and practically falling apart. Drain well, then return them to the pot. Add the butter, warm milk, and sour cream, and mash until smooth and velvety. Taste and season with salt and black pepper, adjusting as needed for that perfect balance.
Step 2: Prepare the Steak Bites
While the potatoes are cooking, get your steak ready. Pat the cubes dry with paper towels—this is key for getting that gorgeous golden-brown crust. Sprinkle generously with salt and black pepper. Heat the olive oil in a large skillet over high heat until shimmering. Working in batches if necessary (don’t crowd the pan!), sear the steak bites for 2 to 3 minutes per side until nicely browned on the outside and cooked to your preferred doneness. Remove the steak bites from the skillet and set them aside on a plate.
Step 3: Make the Garlic Butter Sauce
Turn the heat down to medium and drop the butter into the same skillet. Once it melts and bubbles, add the minced garlic. Stir continuously for about 30 seconds, just until fragrant—don’t let it brown. Return the steak bites to the pan and toss them in all that glorious garlic butter until they’re coated and glistening. Sprinkle with fresh parsley for a burst of color and freshness.
Step 4: Assemble and Serve
Spoon a generous helping of creamy mashed potatoes onto each plate, then pile on the garlic butter steak bites. Don’t forget to drizzle any extra garlic butter sauce over the top—it’s liquid gold. Serve immediately, while everything is piping hot and at peak deliciousness.
How to Serve Garlic Butter Steak Bites and Mash

Garnishes
A sprinkle of chopped parsley right before serving adds color and a fresh note that lifts the richness of the dish. A little cracked black pepper or a pinch of flaky sea salt on top makes it restaurant-worthy. If you’re feeling extra fancy, a dusting of parmesan cheese or a drizzle of truffle oil can take things over the top.
Side Dishes
Garlic Butter Steak Bites and Mash are hearty enough to stand alone, but they also play well with crisp green beans, roasted broccoli, or a fresh mixed greens salad. If you want to keep things classic, warm dinner rolls or a simple baguette are perfect for sopping up every last drop of garlic butter.
Creative Ways to Present
For a dinner party twist, try serving the steak bites and mashed potatoes in individual ramekins or mini cast-iron skillets. For a casual crowd, pile everything onto a big platter and let everyone dig in family-style. You can even turn this into a fun appetizer by skewering the steak bites and offering them over a dollop of mash on tasting spoons—guaranteed to wow your guests.
Make Ahead and Storage
Storing Leftovers
If you find yourself with leftovers (lucky you!), store the steak bites and mashed potatoes separately in airtight containers in the refrigerator. They’ll stay fresh and flavorful for up to 3 days, making them perfect for a quick lunch or easy dinner the next day.
Freezing
Mashed potatoes freeze surprisingly well—just transfer them to a freezer-safe container, smoothing the top, and cover tightly. The steak bites can be frozen too, although they’re best enjoyed fresh. Freeze each component for up to a month, and thaw overnight in the fridge before reheating.
Reheating
Gently reheat mashed potatoes in the microwave or on the stovetop, stirring in a splash of milk or butter to revive their creamy texture. For the steak bites, a quick reheat in a hot skillet helps preserve their tenderness and reawakens the garlic butter flavor. Avoid microwaving the steak for too long, as it can overcook.
FAQs
Can I use a different cut of steak?
Absolutely! While sirloin and ribeye are top choices for Garlic Butter Steak Bites and Mash thanks to their tenderness and flavor, you can also use strip steak or tenderloin. Just aim for well-marbled cuts for the best results.
What can I substitute for sour cream in the mashed potatoes?
If you don’t have sour cream, you can use plain Greek yogurt, crème fraîche, or even a little cream cheese for extra tang and richness in your mash.
How can I make this dish even more flavorful?
Add a splash of Worcestershire sauce or a squeeze of fresh lemon juice to the garlic butter for a punch of umami and brightness. A sprinkle of smoked paprika or chili flakes can also give your Garlic Butter Steak Bites and Mash a little extra kick.
Is this recipe gluten-free?
Yes! Garlic Butter Steak Bites and Mash are naturally gluten-free, as long as you double-check that your sour cream and any optional garnishes you use are gluten-free as well.
Can I make the mashed potatoes ahead of time?
Definitely. Prepare the mash a day in advance and store it in the fridge. When ready to serve, gently reheat with a little extra butter or milk to restore their creamy consistency before topping with the hot steak bites.
