Ingredients Overview

This steak and potatoes recipe uses simple, high-impact ingredients to build bold flavor in every bite.

Steak (Sirloin, Ribeye, or Strip Steak)

Choose a well-marbled cut like sirloin or ribeye for tenderness and rich flavor. Cube into 1–1.5-inch pieces for even cooking. Pat the steak dry to get that perfect sear.

Tip: Let steak come to room temperature for 20–30 minutes before cooking for even browning.

Baby Potatoes

Small yellow or red potatoes work best—they hold their shape and crisp up nicely in a skillet. Slice them in half or quarters depending on size.

Optional Swap: Use fingerlings or even sweet potatoes for a twist.

Butter

Butter adds richness and becomes infused with garlic and herbs. Use unsalted to control salt levels, and finish with a final spoonful for that signature garlic butter gloss.

Garlic

Fresh garlic is essential. Mince it finely or crush it to release its aromatic oils—don’t use garlic powder in place of fresh here.

Olive Oil

Used for sautéing and searing—olive oil helps prevent butter from burning and adds a smooth richness to the dish.

Fresh or Dried Herbs

• Thyme, rosemary, or parsley complement steak beautifully.

• Use fresh herbs for best flavor, but dried herbs work in a pinch.

Salt & Pepper

Don’t skimp—these simple seasonings are essential for flavor, especially when searing steak.

Step-by-Step Instructions

1. Prep the Ingredients

• Cut 1.25–1.5 lbs steak into bite-sized cubes.

• Halve or quarter 1.5 lbs baby potatoes.

• Mince 4–5 cloves of garlic.

• Chop a handful of parsley or strip fresh rosemary/thyme from stems.

2. Cook the Potatoes

Heat 1.5 tablespoons olive oil in a large skillet over medium heat. Add the potatoes cut-side down. Season with salt and pepper.

Cover and cook for 8–10 minutes, stirring occasionally, until potatoes are golden brown and fork-tender. Remove from the pan and set aside.

Pro Tip: Covering helps steam them through before crisping.

3. Sear the Steak

Increase heat to medium-high. Add another 1 tablespoon olive oil to the same pan.

Season steak cubes generously with salt and pepper. Add to the hot skillet in a single layer—don’t overcrowd.

Sear for 2–3 minutes without moving to develop a crust, then stir and cook another 2–3 minutes until browned and just cooked through.

Remove steak and set aside (you can tent with foil to keep warm).

4. Make the Garlic Butter Sauce

Reduce heat to medium-low. Add:

• 3 tablespoons unsalted butter

• Minced garlic

• Chopped fresh herbs (or 1 tsp dried)

Sauté for 30–60 seconds until fragrant, scraping up any browned bits from the pan. Be careful not to burn the garlic.

5. Combine and Finish

Return the cooked steak and potatoes to the skillet. Toss everything in the garlic butter until coated and heated through—about 1–2 minutes.

Taste and adjust seasoning if needed. Finish with fresh parsley and an optional squeeze of lemon for brightness.
