Ingredients
For the Butter Garlic Steak Bites:
- 1 lb sirloin steak (or tenderloin/ribeye for extra richness), trimmed of excess fat and cut into 1-inch cubes
- 2 tablespoons olive oil (or avocado oil)
- 3 tablespoons unsalted butter, divided
- 3–4 cloves garlic, very finely minced (or 1 teaspoon garlic powder for milder flavor)
- Salt and freshly ground black pepper, to taste (be generous!)
- Optional: ½ teaspoon smoked paprika or Italian seasoning for subtle depth
- 1–2 tablespoons fresh parsley, finely chopped (for garnish)
For the Creamy Mashed Potatoes:
- 1½ lbs Yukon Gold potatoes (or russet), peeled and cut into 1–1½ inch chunks
- ¼–⅓ cup warm milk (whole or 2%; add more for creamier texture)
- 2–3 tablespoons unsalted butter
- Salt and freshly ground black pepper, to taste
- Optional: 2–3 tablespoons sour cream or cream cheese for extra silkiness
Step-by-Step Instructions
- Start the potatoes:
Place potato chunks in a medium saucepan and cover with cold water by about 1 inch. Add a generous pinch of salt. Bring to a boil over medium-high heat, then reduce to a simmer. Cook 15–20 minutes until fork-tender (they should break apart easily but not fall apart). - Prep the steak bites:
While potatoes cook, pat steak cubes very dry with paper towels—this ensures a great sear. Season generously on all sides with salt, black pepper (and optional paprika/seasoning). Let sit at room temperature while you wait for the pan to heat. - Sear the steak:
Heat 2 tablespoons olive oil in a large cast-iron or heavy skillet over medium-high heat until shimmering (but not smoking). Add steak cubes in a single layer (work in batches if needed—don’t overcrowd). Sear undisturbed 2–3 minutes per side until deeply golden-brown and crusty. (For medium-rare, aim for 130–135°F internal; they’ll finish in the butter.) Remove to a plate and tent loosely with foil. - Make the garlic butter sauce:
Reduce heat to medium. Add 2–3 tablespoons butter to the hot skillet. Once melted and foaming, add minced garlic. Cook 30–60 seconds, stirring constantly, until fragrant and lightly golden (don’t let it burn). Return steak bites to the pan and toss gently to coat in the garlic butter. Cook 1–2 minutes more to heat through and glaze. Remove from heat and sprinkle with fresh parsley. - Finish the mashed potatoes:
Drain potatoes thoroughly. Return to the warm pot over low heat for 1 minute to evaporate excess moisture. Add warm milk and butter. Mash with a potato masher or fork until smooth and creamy (leave a few small chunks for texture if desired). Stir in optional sour cream or cream cheese for extra richness. Season generously with salt and pepper. Taste and adjust—add more warm milk if too thick. - Serve & enjoy:
Spoon a generous mound of creamy mashed potatoes onto plates. Top with butter-garlic steak bites. Spoon extra garlic butter from the pan over everything. Garnish with more fresh parsley. Serve hot and dig in!
Serving Suggestions:
- With steamed green beans, roasted broccoli, or a simple side salad to balance richness.
- Crusty bread or dinner rolls for sopping up extra garlic butter.
- Pair with a crisp red wine (Pinot Noir) or cold beer.
Pro Tips & Variations:
- Best sear: High heat + dry steak = crispy edges. Don’t move cubes until ready to flip.
- Garlic intensity: Use fresh minced garlic for bold flavor; garlic powder for milder.
- Extra creamy potatoes: Warm milk prevents clumping; add butter last for silkiness.
- Spicy twist: Add red pepper flakes or a dash of hot sauce to the garlic butter.
- Make ahead: Boil potatoes ahead; reheat and mash fresh. Sear steak fresh for best texture.
- Storage: Leftovers keep in fridge 2–3 days. Reheat steak gently in skillet; microwave potatoes with a splash of milk.
