This one-pan garlic butter steak and potatoes brings real steakhouse flavor to your kitchen with one skillet, a handful of ingredients, and about 30 minutes. Nothing fancy: a hot pan, a good sear, and a spoonful of garlic butter over everything at the end. It’s the dinner we make when we want something that feels special on a Tuesday without piling up dishes.
Below you’ll find why the method works, which cuts of steak to buy on a budget, easy swaps, how to tell when your steak is done, and how to store and reheat leftovers so they don’t turn tough.
Why This Recipe Works
- One pan, more flavor. Searing the steak first builds a flavorful crust and leaves behind browned bits in the pan that season the potatoes as they finish cooking in the same skillet.
- Parboiled potatoes finish fast. A quick boil or microwave before they hit the skillet means the potatoes get crispy outside and creamy inside in 6 to 8 minutes, instead of 25.
- Butter goes in after the sear. Butter burns at high heat, so it goes in once the steaks are out. That keeps the garlic golden and sweet, not bitter.
- Resting the steak. While the potatoes cook, the steak rests. The juices settle back into the meat instead of running onto the cutting board.
Ingredients You’ll Need
- 2 steaks (sirloin or ribeye), room temperature
- 1 pound baby potatoes, halved and parboiled
- 3 tablespoons butter
- 3 cloves garlic, smashed
- Fresh rosemary or thyme
- Salt and pepper, to taste
How to Make It
- Season. Season the steaks generously with salt and pepper.
- Sear. Heat a heavy skillet over high heat and sear the steaks for 3 to 4 minutes per side, then remove and let rest.
- Make the garlic butter. Add the butter, garlic, and herbs to the same pan, then add the parboiled potatoes.
- Crisp the potatoes. Cook the potatoes for 6 to 8 minutes, tossing occasionally, until golden and coated in the garlic butter.
- Serve. Slice the steak and serve alongside the potatoes, spooning any extra pan butter over the top.
How to Parboil the Potatoes
Boil the halved potatoes in salted water for 8 to 10 minutes until a fork just slides in, then drain well and let them steam-dry for a couple of minutes. Short on time? Microwave them in a covered bowl with a splash of water for 5 to 6 minutes instead.
Choosing the Right Steak (Without Overspending)
Top sirloin is our go-to for weeknights. It’s lean, beefy, and usually one of the cheaper steaks at the store. Ribeye has more marbling, so it’s juicier and more forgiving, but it costs more. Other good budget options: flat iron, NY strip when it’s on sale, or chuck eye, often called the “poor man’s ribeye.” Look for steaks about 1 inch thick with an even thickness from end to end.
How to Tell When Your Steak Is Done
An instant-read thermometer takes the guessing away. Pull the steak off the heat about 5°F before your target, because it keeps cooking as it rests:
- Rare: 120–125°F
- Medium-rare: 130–135°F
- Medium: 140–145°F
- Medium-well: 150–155°F
The USDA recommends 145°F with a 3-minute rest for whole cuts of beef. Choose the doneness your family is comfortable with.
Tips for the Best Results
- Pat the steaks dry. A dry surface browns; a wet one steams.
- Don’t crowd the pan. If your skillet is small, sear one steak at a time.
- Leave it alone. Resist moving the steak while it sears. It releases from the pan once the crust forms.
- Slice against the grain. Cut across the lines running through the meat for more tender bites, especially with sirloin.
- Turn on the fan. A good sear makes some smoke. That’s normal.
Easy Substitutions
- No baby potatoes: Cut Yukon Gold or red potatoes into 1-inch cubes.
- Dairy-free: Use olive oil or a plant-based butter.
- No fresh herbs: ½ teaspoon dried rosemary or thyme works fine. Add it with the butter.
- Add a vegetable: Toss green beans, asparagus, or mushrooms in with the potatoes for the last 4 to 5 minutes.
- Swap the protein: Boneless chicken thighs (cook to 165°F) or thick pork chops (145°F) also work with this method.
- Add some heat: A pinch of red pepper flakes in the garlic butter.
Storage and Reheating
- Fridge: Store steak and potatoes in an airtight container for up to 3 to 4 days.
- Freezer: Freeze sliced steak for up to 2 to 3 months. Potatoes get a bit grainy when frozen, so they’re best eaten fresh.
- Reheat without drying out: Warm the steak slices in a skillet over low heat with a small pat of butter for 1 to 2 minutes. Re-crisp the potatoes in the air fryer at 375°F for 4 to 5 minutes.
- Leftover idea: Chop leftover steak and potatoes into a breakfast hash with a fried egg on top.

Notes
Frequently Asked Questions
Can I skip parboiling the potatoes?
You can, but raw potatoes take 20 to 25 minutes in the skillet and the steak would get cold. Parboiling (or microwaving) keeps this a 30-minute meal.
What’s the best pan for this recipe?
A 12-inch cast iron skillet holds heat best and gives the deepest crust. A heavy stainless steel pan also works. Avoid thin nonstick pans at very high heat.
Why is my steak tough?
Usually one of three things: it was overcooked, it didn’t rest, or it was sliced with the grain. A thermometer and a 5-minute rest fix most of it.
Can I make this in the air fryer?
Yes. Air fry the parboiled potatoes at 400°F for 12 to 15 minutes, and cook 1-inch steaks at 400°F for 8 to 12 minutes, flipping halfway. Melt the garlic butter separately and pour it over both.
