- Sirloin steak (1 1/2 pounds): Choose well-marbled steak for tender, flavorful bites.
- Salt (1 teaspoon): Essential for seasoning both the steak and the mash to bring out their natural flavors.
- Black pepper (1/2 teaspoon): Adds a subtle heat and depth to the steak and potatoes.
- Smoked paprika (1 teaspoon): Infuses the steak bites with a smoky, slightly sweet undertone.
- Olive oil (1 tablespoon): Provides a perfect searing base for the steak bites.
- Butter (4 tablespoons, divided): Key for rich, luscious garlic butter and creamy mashed potatoes.
- Garlic cloves (5, minced): Delivers irresistible aroma and bold flavor in the butter sauce.
- Worcestershire sauce (1 tablespoon): Adds a savory, tangy complexity to the steak bites.
- Fresh parsley (1 tablespoon, chopped): Brings fresh color and a mild herbal note to finish the dish.
- Russet potatoes (2 pounds, peeled and cubed): The ideal variety for ultra-smooth, fluffy mashed potatoes.

How to Make Garlic Butter Steak Bites and Mash Recipe
Step 1: Season and Sear the Steak Bites
Start by tossing the sirloin steak cubes with salt, black pepper, and smoked paprika. This simple seasoning sets the stage for a flavor-packed bite. Heat olive oil in a large skillet over medium-high heat, then add half the steak bites in a single layer to get that beautiful sear. Cook for 2 to 3 minutes per side until nicely browned, then transfer to a plate and repeat with the remaining pieces. This technique locks in juices and forms a caramelized crust that’s utterly mouthwatering.
Step 2: Create the Garlic Butter Sauce
Once all the steak bites are seared and resting, lower the heat to medium and add 3 tablespoons of butter to the skillet. When the butter melts, toss in the minced garlic and cook until fragrant, just a minute or so. The aroma at this point is absolutely irresistible and sets the tone for what’s next.
Step 3: Toss Steak Bites in Garlic Butter
Return the steak bites to the skillet and stir them gently with the garlic butter and Worcestershire sauce. Cook for another minute to coat each piece thoroughly, allowing all those flavors to meld beautifully. Finally, sprinkle chopped fresh parsley over the top and remove from heat to preserve the bright herbal finish.
Step 4: Prepare the Creamy Mashed Potatoes
While the steak bites get their final flavor boost, bring a large pot of salted water to a boil and cook the cubed russet potatoes for 12 to 15 minutes or until fork-tender. Drain them well and return them to the pot. Add the remaining butter, warm milk, sour cream, salt, and pepper, then mash everything together until smooth and creamy. The sour cream lends a subtle tang, making your mashed potatoes delightfully rich and silky.
Step 5: Plate and Serve
For the finishing touch, serve the garlic butter steak bites over a generous mound of the luscious mashed potatoes. The combination of sizzling garlic butter steak with velvety mash is truly next-level comfort food, perfect for impressing family or treating yourself to something special.
How to Serve Garlic Butter Steak Bites and Mash Recipe

Garnishes
Brighten your plate by sprinkling extra fresh parsley over the top just before serving. For an added burst of color and zing, consider a light dusting of smoked paprika or a few red pepper flakes if you love a touch of heat. These small touches elevate the look and taste, making your dish feel restaurant-worthy.
Side Dishes
This dish is quite hearty, but pairing it with a crisp green salad featuring a tangy vinaigrette cuts through the richness beautifully. Roasted or steamed green beans, asparagus, or sautéed garlic spinach make excellent veggie sides, adding a fresh crunch and balance to the meal.
Creative Ways to Present
For a fun presentation twist, serve the steak bites and mash in individual cast-iron skillets or rustic bowls for a cozy, casual vibe. Layering the mash first with steak bites piled on top, then drizzling the garlic butter sauce over everything, not only looks stunning but keeps every bite perfectly saucy and delicious.
Make Ahead and Storage
Storing Leftovers
If you find yourself with leftovers, they store beautifully in an airtight container in the refrigerator for up to 3 days. This way, you can enjoy the flavors again without any hassle, just reheat gently to keep that garlic butter magic intact.
Freezing
While the steak bites are best fresh to maintain tenderness, the mashed potatoes freeze very well. Store mashed potatoes in a freezer-safe container for up to 2 months. When ready to eat, thaw overnight in the fridge before reheating to preserve their smooth, creamy texture.
Reheating
To reheat, warm the steak bites gently in a skillet over medium heat to avoid drying them out. For the mashed potatoes, add a splash of milk or cream while reheating to revive their creamy consistency. Avoid microwaving on high heat to prevent uneven warming and maintain the dish’s delicious qualities.
FAQs
Can I use a different cut of steak for this recipe?
Absolutely! Ribeye or New York strip steaks are excellent substitutes if you want an even more tender bite. Just be sure to cut them into evenly sized cubes for consistent cooking.
Is it possible to make this recipe dairy-free?
Yes! You can swap butter with dairy-free margarine and use a plant-based milk alternative along with a non-dairy sour cream to enjoy a similar creamy texture without dairy.
How do I prevent the steak bites from overcooking?
Make sure your skillet is properly preheated and avoid overcrowding the pan. Sear the steak cubes in batches for a quick, even cook that locks in juices while achieving a golden crust.
Can I add a spicy kick to the garlic butter?
Definitely! Adding a pinch of red pepper flakes to the garlic butter while it cooks gives the dish a delightful warmth that complements the robust flavors beautifully.
What’s the best way to make mashed potatoes extra creamy?
Using russet potatoes, warming your milk before mixing, and mashing thoroughly all help. Adding a splash of heavy cream can also amplify the richness if you’re looking to spoil yourself.
