Ingredients
Scale
1.5 lb (680 g) sirloin or ribeye steak, trimmed and cut into 1‑in cubes
2 Tbsp olive oil
4 Tbsp unsalted butter, divided
4 garlic cloves, minced
1 tsp fresh thyme leaves (or ½ tsp dried thyme)
Salt & pepper, to taste
— For the Mash —
2 lb (900 g) Yukon Gold or russet potatoes, peeled and quartered
½ cup milk (or cream)
2 Tbsp unsalted butter
Salt & pepper, to taste
Optional garnish: chopped parsley
Instructions
Place potatoes in a pot, cover with water, add a pinch of salt, and bring to a boil. Cook until fork-tender, about 15–18 minutes.
While potatoes cook, pat steak cubes dry and season generously with salt and pepper.
Heat olive oil in a large skillet over medium-high heat until shimmering.
Add the steak bites in a single layer (work in batches if needed) and sear 2–3 minutes per side until browned and cooked to desired doneness. Transfer to a plate and tent loosely with foil.
In the same pan over medium heat, add 2 Tbsp butter. Once melted, stir in garlic and thyme; cook 30 seconds until fragrant.
Return steak bites to the skillet, add remaining 2 Tbsp butter, and toss to coat in garlic-thyme butter. Cook another minute, then remove from heat.
Drain potatoes and return to pot. Mash with butter and warm milk until smooth and creamy. Season with salt and pepper.
Serve steak bites over a bed of mashed potatoes, spooning extra garlic butter from the pan on top. Garnish with parsley if desired.
Notes
Use room-temperature milk and warm potatoes to help the mash come together smoothly.
Don’t overcrowd the pan when searing steak—working in batches ensures a good crust.
For extra richness, stir a dollop of sour cream or cream cheese into the mash.
Leftover steak bites reheat well in a skillet — avoid microwaving to preserve texture.
