Preparation

Step 1: Prepare the Steak

Pat the steak cubes dry with paper towels to remove excess moisture. Season evenly with salt, pepper, smoked paprika, onion powder, thyme, and Worcestershire sauce. Let the meat rest at room temperature for about 20 minutes to ensure even cooking.

⸻

Step 2: Prepare the Potatoes

Peel and cut the potatoes into evenly sized chunks. Place them in a large pot and cover with cold salted water. Bring to a boil and cook for 15–20 minutes, or until fork-tender.

⸻

Step 3: Make the Garlic Butter

In a small bowl, combine softened butter with minced garlic, rosemary, and parsley. Set aside until needed.

Cooking Instructions

Cook the Steak Bites

Heat olive oil in a large skillet over medium-high heat until shimmering.

Add the steak cubes in a single layer without overcrowding the pan. Cook in batches if necessary.

Sear for about 2–3 minutes per side until a rich brown crust forms while the inside remains juicy.

Reduce the heat to medium. Add the garlic butter mixture and spoon the melted butter over the steak for 1–2 minutes until fragrant.

Remove from the heat and keep warm.

⸻

Prepare the Creamy Mashed Potatoes

Drain the cooked potatoes thoroughly.

Mash until smooth using a potato masher or potato ricer.

Add butter, warm milk, heavy cream, roasted garlic, Parmesan cheese (if using), salt, and pepper.

Mix until creamy and fluffy. Avoid overmixing to maintain a light texture.

⸻

Serving Instructions

Spoon a generous serving of creamy mashed potatoes onto each plate.

Top with sizzling garlic butter steak bites.

Drizzle the remaining garlic butter from the skillet over the steak and potatoes.

Garnish with chopped parsley or chives and serve immediately with your favorite vegetables or fresh bread.

Cooking Methods

Cast-Iron Skillet Method

A cast-iron skillet provides excellent heat retention, creating a beautifully caramelized crust on the steak while locking in the juices.

Grill Method

Thread the steak cubes onto skewers and grill over medium-high heat before tossing them in garlic butter.

Oven Finish Method

After searing, finish thicker steak bites in a 400°F (200°C) oven for 3–5 minutes to reach your preferred doneness.

Air Fryer Method

Cook seasoned steak bites in a preheated air fryer at 400°F (200°C) for 6–8 minutes, shaking halfway through. Toss with melted garlic butter before serving.

Tips for Success

  • Use well-marbled steak for the juiciest results.
  • Pat the steak dry before cooking to achieve a perfect sear.
  • Do not overcrowd the pan, as this causes steaming instead of browning.
  • Allow the steak to rest for a few minutes after cooking.
  • Warm the milk and cream before adding them to the potatoes for a smoother mash.
  • Taste and adjust the seasoning before serving.
