Before you start
Before turning on the heat, gather and measure all your ingredients to ensure a smooth cooking process. Peel the potatoes and cut them into uniform two-inch chunks so they boil evenly.
Mince the fresh garlic cloves and finely chop the fresh herbs. Remove the steak from the refrigerator thirty minutes before cooking to take the chill off, then pat the cubes dry with paper towels so they are ready for a perfect sear.
Ingredients at a glance (7)
- 2 lb potatoes, peeled and cut into 2-inch chunks
- 4 tbsp butter, cubed
- 1/2 cup grated Parmesan cheese
- 1 1/2 lb steak, cut into 1-inch cubes
- 4 tbsp butter, for searing
- 4 cloves garlic, minced
- 1 tbsp chopped fresh herbs
Instructions
Boiling and Mashing the Potatoes
- Boil the PotatoesPlace the peeled and cubed potatoes into a large pot and cover them with cold water by about one inch. Bring the water to a boil over high heat. Reduce the heat to medium and simmer for fifteen to twenty minutes until the potatoes are completely fork-tender.Look for The potatoes should slide off a knife easily when pierced.Tip Always start potatoes in cold water so they cook evenly from the edges to the center.
- Mash and Season the PotatoesDrain the potatoes thoroughly and return them to the warm pot. Mash them using a potato ricer or hand masher until smooth. Gently fold in four tablespoons of butter and the grated parmesan cheese until the mixture is velvety, creamy, and fully incorporated, then cover to keep warm.Look for The potatoes should look smooth, creamy, and hold soft peaks.Tip Ensure the butter is at room temperature so it melts quickly into the hot potatoes.
At the end of this first phase, the potato chunks should be completely fork-tender and slide off a knife with absolutely no resistance. After draining and mashing, they will transform into a steaming, fluffy mound.
Once the butter and parmesan cheese are fully incorporated, the potatoes should look incredibly smooth, velvety, and hold soft peaks, releasing a rich aroma of melted butter and savory cheese.
Searing the Steak Bites
- Sear the Steak BitesHeat a large cast-iron skillet over high heat until smoking. Add the remaining butter and immediately add the steak bites in a single layer, ensuring they do not crowd the pan. Sear without moving for two minutes to develop a deep, caramelized crust, then flip and sear for another minute.Look for A rich, dark brown crust should form on the bottom of the steak bites.Tip Pat the steak completely dry with paper towels before cooking to ensure a perfect sear.
By the end of this phase, the steak bites should have a deeply caramelized, dark brown crust on all sides. You will hear a loud, active sizzle in the pan, and the kitchen will fill with the rich, savory aroma of seared beef. It is crucial that the pan remains hot enough to brown the meat quickly without crowding, ensuring the interiors stay tender and juicy.
Basting with Garlic Herb Butter
- Baste with Garlic Herb ButterReduce the heat to medium and add the minced garlic and chopped herbs to the skillet. Toss the steak bites continuously in the foaming garlic butter for one to two minutes, coating each piece thoroughly. Ensure the internal temperature of the steak reaches 145°F (63°C) using a meat thermometer, then remove from the heat and let the meat rest for at least three minutes before serving over the warm mashed potatoes.Look for The butter should be foaming, golden, and highly fragrant with garlic.Safe temperature 145°F (63°C) internal temperature (steaks, chops and roasts)Tip Do not let the garlic burn; reduce the heat if the pan is too hot.
At the final checkpoint, the butter in the pan should be foaming, golden-brown, and infused with the fragrance of toasted garlic and fresh herbs. The steak bites will be glistening with a glossy pan sauce, and when tested with a meat thermometer, the thickest cube will register 145 degrees Fahrenheit. The meat must then rest for three minutes to allow the juices to redistribute.
Common mistakes
One of the most common mistakes is crowding the skillet when searing the steak bites. If too many cold meat cubes are added to the pan at once, the pan temperature drops rapidly, causing the steak to release its juices and steam rather than sear.
This results in grey, tough meat without a crust. To avoid this, sear the steak in batches if necessary, ensuring there is plenty of space between each piece for steam to escape.
How to tell it’s done
Determining the perfect doneness for steak bites requires monitoring both the external crust and the internal temperature. The exterior should be deeply browned and caramelized.
To ensure food safety, the internal temperature of the whole cut beef must reach at least 145 degrees Fahrenheit (63 degrees Celsius) when measured with an instant-read thermometer. Once this temperature is reached, immediately remove the steak from the heat and let it rest for three minutes before serving.
