Garlic Butter Steak Bites and Potatoes

What Makes It Work

• Parcooked potatoes. Raw potatoes take 20-plus minutes to cook through in a skillet. Microwaved first, they just need to crisp.
• Steak seared in two batches. An uncrowded, very hot pan browns the outside instead of steaming the meat gray.
• Garlic added last, over medium heat. It turns fragrant and sweet in 30–60 seconds instead of burning.
• One pan. The potatoes, steak, and butter all pick up the same browned bits.

What You'll Need

• Top sirloin steak. Tender and affordable. Ribeye or New York strip are richer and cost more. Skip stew meat, which needs long cooking.
• Baby potatoes. Yukon Gold or red, halved so they have a flat side to crisp.
• Neutral oil. Avocado or canola handles high heat; butter alone would burn.
• Butter and garlic. Five cloves for the finishing sauce.
• Thyme and parsley. Thyme for an earthy note, parsley for freshness.
• Salt, pepper, and red pepper flakes. The flakes are optional.

How to Cut the Steak

Pat the steak dry and trim any thick fat or gristle. Cut it into 1-inch-wide strips, then across into 1-inch cubes. Same-size pieces finish at the same time. If you can see the grain (long lines of muscle), cut the strips across it so each bite is more tender.

How to Make It

Put the halved potatoes in a microwave-safe bowl with 2 tablespoons water, cover, and microwave 5–6 minutes, until just tender. Drain and pat them dry. Heat 1 tablespoon oil in a 12-inch skillet over medium-high, add the potatoes cut side down with a little salt, and cook 8–10 minutes, turning once, until golden and crisp. Move them to a plate.

Season the steak right before cooking. Add the rest of the oil and turn the heat to high. Sear half the cubes in a single layer without moving them for 2 minutes, then turn and cook 1–2 minutes more, until they reach 145°F. Move them to the plate and repeat with the rest.

Lower the heat to medium. Add the butter, garlic, thyme, and pepper flakes and stir 30–60 seconds, just until the garlic smells fragrant. Return the steak, potatoes, and any juices and toss for 1 minute. The steak gets its 3-minute rest while the butter melts. Sprinkle with parsley and serve.

Doneness Guide

USDA recommends cooking whole cuts of beef, including cubed steak cut from a whole roast or steak, to 145°F with a 3-minute rest. Many cooks pull at 130–135°F for medium-rare, which is a personal choice. An instant-read thermometer in the thickest cube takes the guesswork out.

Troubleshooting

• Tough, chewy steak. Overcooked or cut from a tough cut. Use sirloin and pull it as soon as it hits temperature.
• Gray, steamed steak. The pan was crowded or not hot enough. Pat the cubes dry and cook in two batches.
• Burned garlic. It went in over high heat. Lower the heat before adding the butter.
• Soggy potatoes. They were wet or crowded. Dry them after parcooking and give them room.
• Bland. Season the steak right before searing and salt the potatoes as they crisp.

Variations

• Mushrooms. Add 8 ounces sliced mushrooms with the potatoes.
• Green beans. Toss in a handful of trimmed green beans with the garlic butter and cook 2–3 minutes.
• Cajun. Season the steak with Cajun seasoning instead of salt and pepper.
• Parmesan. Sprinkle with grated Parmesan right before serving.
• Frozen potatoes. Thawed frozen roasted potatoes work; pat them dry and crisp 8–10 minutes.

Storing and Reheating

Refrigerate leftovers within 2 hours and eat within 3–4 days. Reheat in a hot skillet for 1–2 minutes, just until warmed through; the microwave overcooks steak quickly. Leftovers are good over a salad or tucked into a wrap.

What to Serve With It

A crisp Greek village salad, brown sugar glazed roasted carrots, steamed asparagus, or crusty bread for the garlic butter. If you'd rather roast the potatoes and skip the skillet step, garlic butter roasted potatoes or these simple rosemary roasted potatoes are good oven options. Planning a night in?

Cook's Tips

• Cast iron or stainless, not nonstick. You need a pan that can take high heat and build a crust.
• Let the oil shimmer before the steak goes in. A hot pan means a fast sear.
• Don't move the cubes for the first 2 minutes. That's when the crust forms.
• Slice one cube if you don't have a thermometer. Medium should be pink in the center.
