Ingredients
  

Core Ingredients:
  • 1.5 lbs sirloin steak cut into 1-inch cubes
  • 1.5 lbs baby potatoes halved
  • 3 tbsp olive oil
  • 3 tbsp unsalted butter
  • 4 garlic cloves minced
  • 1 tsp Italian seasoning
  • Salt and pepper to taste
  • Fresh chopped parsley for garnish
Optional Add-ins:
  • Crushed red pepper flakes for a little heat
  • A squeeze of lemon juice for brightness
  • Sliced mushrooms or bell peppers
  • Fresh thyme or rosemary for extra herby depth

Method
 

Prep the Potatoes
  1. Boil potatoes in salted water for 6–8 minutes until just tender. Drain and pat dry.
Sear the Potatoes
  1. Heat 2 tbsp olive oil in a large skillet over medium-high heat. Add the potatoes cut-side down and cook until golden and crispy, about 8–10 minutes. Remove from pan and set aside.
Cook the Steak
  1. Season steak cubes with salt, pepper, and Italian seasoning. Add remaining oil to the skillet and sear steak in a single layer (in batches if needed) for about 2–3 minutes per side. Remove and set aside.
Make the Garlic Butter
  1. Lower heat to medium. Add butter and garlic to the skillet, stirring until fragrant (about 30 seconds).
Combine Everything
  1. Return the potatoes and steak to the skillet. Toss in the garlic butter until everything is coated and sizzling hot. Garnish with parsley.
Serve
  1. Serve immediately straight from the pan — with bread, a green salad, or whatever makes your taste buds happy!

Notes

Garlic Butter Steak and Potatoes Skillet – Helpful Tips

Cooking Tips & Techniques
Choose well-marbled cuts like ribeye, sirloin, or NY strip for juicy, flavorful steak bites.
Cut steak into even, bite-sized pieces and let it rest at room temp for 20–30 minutes before searing.
Parboil or microwave baby potatoes to soften them slightly before pan-searing for that golden crisp.
Use a heavy skillet (cast iron is best!) and cook steak in batches to avoid steaming—give it that perfect crust.
Add garlic and butter after searing to infuse flavor without burning—spoon that garlicky butter over everything.
Serving Suggestions
Serve hot right out of the skillet with chopped parsley and a squeeze of lemon for brightness.
Pair with a side salad, roasted veggies, or crusty bread to soak up all that buttery goodness.
Top with crumbled blue cheese or drizzle with balsamic glaze for an elevated finish.
Great for date nights, steakhouse-style dinners, or comfort food cravings.
Serve with a glass of red wine or iced tea, depending on the mood.
Make-Ahead & Storage
Make-Ahead: Parboil potatoes and cut steak ahead of time—store separately and cook fresh for best results.
Refrigerator: Store leftovers in an airtight container for up to 3 days.
Freezer: Freeze cooked steak and potatoes for up to 2 months—reheat gently for best texture.
Reheat: Reheat in a skillet with a touch of butter over medium heat; microwave only if necessary, as steak can toughen.
Tasty Variations to Try
Herb Upgrade: Add fresh rosemary or thyme sprigs when melting the butter for an earthy finish.
Spicy Kick: Sprinkle with crushed red pepper flakes or finish with a chili garlic compound butter.
Cheesy Top: Sprinkle with shredded Parmesan or melty provolone just before serving.
Garlic Cream Sauce: Turn the skillet drippings into a quick cream sauce with a splash of cream and extra garlic.
Low-Carb Swap: Replace potatoes with sautéed cauliflower or roasted radishes for a keto-friendly twist.
