Before you start

Before beginning, gather all necessary equipment and ingredients to ensure a smooth cooking process. Peel and chop the potatoes into uniform cubes so they boil evenly. Measure out the butter and parmesan cheese.

Mince the garlic cloves and set them aside. Pat the steak cubes completely dry with paper towels; removing surface moisture is essential for achieving a deep, golden-brown crust during the sear.

Ingredients at a glance (6)
  • 2 lb potatoes, peeled and cubed
  • 1/2 cup butter, divided
  • 1/2 cup parmesan cheese, grated
  • 1 1/2 lb steak, cut into 1-inch cubes
  • 1 tbsp seasoning
  • 4 cloves garlic, minced

Instructions

Preparing and Whipping the Potatoes

  1. Boil the Potatoes
    Place the peeled and cubed potatoes in a large pot and cover with cold water. Bring to a boil over high heat, then reduce the heat to medium and simmer until the potatoes are completely fork-tender, about 15 minutes. Drain the water thoroughly.
    Look for The potatoes are ready when a fork slides into the center of the cubes with absolutely no resistance.
    Tip Starting the potatoes in cold water ensures they cook evenly from the edges to the center.
  2. Whip the Potatoes
    Mash the hot potatoes in the pot. Add half of the butter and the parmesan cheese. Whip with a hand mixer or a sturdy spoon until completely smooth, fluffy, and creamy, then cover the pot to keep them warm.
    Look for The potatoes should look light, fluffy, and completely free of lumps.
    Tip Warm the butter slightly before adding it to keep the potatoes hot and velvety.

At the end of this phase, the potatoes should be completely tender when pierced with a fork, with no resistance in the center. Once drained, mashed, and whipped with the butter and parmesan, they will look exceptionally smooth, fluffy, and pale yellow.

They should hold their shape gently on a spoon and release a rich, buttery aroma with a distinct hint of savory parmesan cheese.

Searing the Steak Bites

  1. Sear the Steak
    Pat the steak cubes completely dry with paper towels and coat them with the seasoning. Heat half of the remaining butter in a large skillet over high heat. Once the butter is foaming, add the seasoned steak cubes in a single layer. Sear without moving for 2 minutes to form a deep brown crust.
    Look for A rich, dark brown crust should form on the bottom side of the steak cubes.
    Tip Drying the meat thoroughly is the secret to achieving a perfect, restaurant-style caramelized crust.
  2. Cook to Temperature
    Flip the steak cubes and cook for an additional 1 to 2 minutes. The internal temperature must reach at least 145°F (63°C) for food safety. Remove the skillet from the heat and transfer the steak bites to a plate. Let the meat rest for at least 3 minutes to keep the juices locked inside.
    Look for The steak cubes will feel slightly firm to the touch and have an even sear on all sides.
    Safe temperature 145°F (63°C) internal temperature (steaks, chops and roasts)
    Tip Do not skip the resting period; it is essential for keeping the steak tender and juicy.

By the end of this phase, the steak cubes will have a deeply caramelized, dark brown crust on the outside while remaining tender and juicy. The skillet will sizzle loudly, and the aroma of seared beef will fill the kitchen. A meat thermometer inserted into the thickest cube must read at least 145 degrees Fahrenheit (63 degrees Celsius) before removing the meat to rest.

Glazing with Garlic Butter and Assembling

  1. Make Garlic Butter and Assemble
    Reduce the skillet heat to medium-low. Melt the remaining butter in the same skillet, scraping up any browned bits from the bottom. Add the minced garlic and sauté for 1 minute until fragrant. Return the rested steak bites and their juices to the pan, tossing to coat in the garlic butter. Spoon the warm mashed potatoes onto plates, top with the steak bites, and drizzle the rich garlic butter sauce over the top.
    Look for The garlic should turn a light golden color and smell highly fragrant without browning too much.
    Tip Watch the garlic closely, as it can burn quickly and become bitter in a hot pan.

At the final checkpoint, the melted butter in the pan will be foaming and infused with golden, fragrant minced garlic. The steak bites will be glossy and thoroughly coated in the rich pan sauce. When plated over the warm, fluffy bed of whipped potatoes, the finished dish should look incredibly appetizing, with the savory garlic butter pooling beautifully around the tender beef.

Common mistakes

One common mistake is crowding the skillet when searing the steak bites. If the beef cubes are piled on top of each other, they will steam in their own moisture instead of searing, resulting in a gray color and a tough texture rather than a crisp, brown crust.

Cook the steak in batches if necessary, ensuring there is space between each piece to allow steam to escape and heat to circulate.

How to tell it’s done

To determine perfect doneness, use an instant-read digital meat thermometer inserted into the center of a steak cube. For safe consumption, the internal temperature must reach at least 145 degrees Fahrenheit (63 degrees Celsius).

Additionally, letting the meat rest for at least three minutes after cooking is vital. This resting period allows the muscle fibers to relax and reabsorb the flavorful juices, ensuring the steak bites remain tender.
