Garlic & Herb Butter Steak Bites Over Mashed Potatoes with Asparagus

A Steakhouse-Worthy Meal at Home

Garlic and herb butter steak bites over mashed potatoes with asparagus is one of those dishes that looks and tastes like it came from a steakhouse but can easily be made right at home. The tender, juicy steak bites are seared until golden brown and tossed in a rich, aromatic garlic butter sauce infused with herbs like thyme, rosemary, and fresh parsley. That buttery coating clings to every bite, making each mouthful taste indulgent and savory.

Comfort Meets Elegance

Plated on a bed of creamy mashed potatoes, these steak bites bring comfort to your plate, and the addition of roasted asparagus cuts through the richness, adding freshness and texture to balance it all out. This meal works whether you’re serving guests or simply treating yourself to something luxurious on a weeknight. The mashed potatoes are whipped with butter and warm milk until smooth and fluffy, creating the perfect base to soak up all that garlic butter sauce.

The Perfect Trio of Flavors

The asparagus is roasted at a high temperature to give it a light char and crispy tips, which contrast beautifully with the soft, rich potatoes and juicy steak. Every part of this meal complements the other—savory, creamy, herby, and fresh—all in one perfect bite.

Ingredients You’ll Need

To make this dish, start by prepping the mashed potatoes. Peel and cube about 2 pounds of russet potatoes, boil them in salted water until fork tender, then mash with ½ cup warm whole milk and ¼ cup butter. Season with salt and pepper to taste and keep warm. While the potatoes boil, prepare the asparagus by trimming off the tough ends and tossing them with olive oil, salt, and pepper. Roast at 425°F for 10–12 minutes until lightly crisped but still vibrant green.

How to Cook the Steak Bites

For the steak bites, use about 1½ pounds of sirloin or strip steak, cut into bite-sized cubes. Pat them dry and season generously with salt and black pepper. Heat a tablespoon of olive oil in a cast iron skillet until smoking hot, then sear the steak cubes in batches for 1–2 minutes per side without overcrowding the pan. Remove them and reduce heat to medium, adding 3 tablespoons of butter, 4 minced garlic cloves, ½ teaspoon thyme, ½ teaspoon rosemary, and a tablespoon of chopped parsley. Let it sizzle for 1–2 minutes, then return the steak bites to the skillet and coat them in the melted herb butter.

Plating and Serving

Spoon creamy mashed potatoes onto a plate, top with those juicy garlic herb steak bites and drizzle any leftover butter sauce from the pan on top. Add a handful of roasted asparagus to the side and garnish with extra herbs if desired. The result is a well-rounded, satisfying dinner full of flavor and texture—perfectly seared meat, silky potatoes, crisp veggies, and garlicky herb richness in every bite.
