Choosing the Best Steak for Steak Bites
The cut of steak matters more than any other choice in this recipe. Because the pieces cook so quickly in a hot pan, you want a cut that is naturally tender and has good beef flavor. Here is how the most common options compare.
| Cut | Texture and flavor | Notes |
|---|---|---|
| Sirloin (top sirloin) | Tender, beefy, lean | Best value and our top pick |
| Ribeye | Very tender, rich, well marbled | Extra juicy, trim large fat pieces |
| New York strip | Tender with a firm bite | Great flavor, a bit pricier |
| Tenderloin (filet) | Buttery soft, mild | Luxurious but costly |
| Sirloin tips | Tender if cut small | Often sold pre-cubed for convenience |
Look for steak that is at least 1 inch thick with bright red color and a little marbling, which is the thin white fat running through the meat. Marbling melts as the steak cooks and keeps it juicy. If you buy a whole steak, cut it yourself into 1-inch cubes so all of the pieces cook at the same speed.
Everything you need: steak, baby potatoes, butter, garlic, olive oil and fresh herbs.
Ingredients for Garlic Butter Steak and Potatoes
- 1½ lb (680 g) sirloin steak, about 1 inch thick, cut into 1-inch cubes
- 1½ lb (680 g) baby potatoes, halved (quartered if large)
- 3 tbsp olive oil, divided
- 4 tbsp (57 g) unsalted butter, divided
- 5 garlic cloves, minced
- 2 sprigs fresh rosemary, plus 1 tsp finely chopped rosemary
- 1 tsp fresh thyme leaves (or ½ tsp dried)
- 1 tsp smoked paprika
- 1 tsp salt, plus more to taste
- ½ tsp freshly ground black pepper
- ¼ tsp red pepper flakes (optional)
- 2 tbsp chopped fresh parsley, for serving
- 1 tsp lemon juice (optional, for brightness)
Ingredient Notes
- Potatoes: Baby potatoes (also sold as creamers or baby Yukons) are ideal because they have thin skins, cook evenly and become creamy inside. Yukon Gold potatoes cut into ¾-inch chunks work just as well.
- Butter: Unsalted butter lets you control the salt. Add it at the end so it does not brown too much or burn.
- Garlic: Fresh garlic is a must here. Jarred garlic is milder and can taste dull in the sauce.
- Herbs: Rosemary and thyme give the butter a woodsy, steakhouse flavor. Parsley adds freshness at the end.
- Oil: Olive oil is fine for the potatoes. For a hotter sear on the steak you can use avocado oil or another high-heat oil.
Equipment You’ll Need
- A large 12-inch cast iron skillet (or heavy stainless steel pan) with a lid or sheet pan to cover it
- A sharp knife and cutting board
- A wooden spoon or spatula
- A digital meat thermometer (helpful but optional)
- Paper towels for drying the steak
How to Make Garlic Butter Steak and Potatoes Skillet
Read through the steps once before you start. The recipe moves quickly once the steak goes in the pan, so have everything chopped and measured ahead of time.
Step 1: Prep the Steak and Potatoes
Cut the sirloin into even 1-inch cubes so every piece cooks at the same speed.
Take the steak out of the fridge about 15 minutes before cooking. Pat it dry with paper towels, trim any large pieces of hard fat and cut it into 1-inch cubes. Season the cubes with ½ teaspoon of the salt, the black pepper and the paprika, then toss to coat. Halve the baby potatoes so they have a flat cut side, which will brown nicely in the pan.
Drying the meat is the step many people skip, and it makes a real difference. Moisture on the surface turns to steam in the hot pan and keeps the steak from browning, so dry cubes give you a deeper crust and more flavor.
Step 2: Brown the Potatoes
Start the potatoes first, cut-side down, so they get a golden crust.
Heat 2 tablespoons of the olive oil in a large cast iron skillet over medium-high heat until it shimmers. Add the potatoes cut-side down in a single layer, sprinkle with the remaining ½ teaspoon of salt and let them cook without stirring for 4 to 5 minutes, until the bottoms are deeply golden.
Stir the potatoes, reduce the heat to medium, cover the pan and cook for 8 to 10 minutes more, stirring once or twice, until a fork slides in easily. Remove the lid for the last couple of minutes so the surface dries and crisps. Move the potatoes to the edges of the pan or onto a plate.
Step 3: Sear the Steak Bites
Sear the steak in a single layer over high heat without crowding the pan.
Turn the heat up to high and add the remaining tablespoon of oil to the empty part of the skillet. When the oil is just starting to smoke, add the steak cubes in a single layer. Work in two batches if your pan is crowded. Let the steak sear without moving it for about 1 to 2 minutes, until a brown crust forms, then turn the pieces and sear the other sides for another 1 to 2 minutes.
You are aiming for a brown outside and a pink, juicy center. Steak bites finish cooking in the garlic butter, so take them off the heat sooner than you think you should. If you use a thermometer, pull the steak at about 125°F (52°C) for medium-rare, which will rise a few degrees as it finishes.
Step 4: Make the Garlic Butter
Spoon the foaming garlic butter over the steak and potatoes.
Reduce the heat to medium-low and push everything to one side. Add 3 tablespoons of the butter, the minced garlic, the rosemary sprigs and the thyme to the empty space. Let the butter melt and foam for 30 seconds, stirring the garlic gently so it becomes fragrant but does not brown.
Tilt the pan slightly and use a spoon to baste the steak and potatoes with the melted butter for about 1 minute. This step is what turns a good skillet into a great one, since the butter carries the garlic and herb flavor onto every piece.
Step 5: Toss, Season and Serve
Stir the steak and potatoes together so everything is coated in the garlic butter. Add the last tablespoon of butter, the chopped rosemary, the red pepper flakes and the lemon juice if you are using it. Taste and add more salt and pepper if needed. Remove the rosemary sprigs, sprinkle with parsley and serve straight from the skillet while it is still sizzling.
Serve it hot, with plenty of the garlic butter spooned over the top.
Steak and Potatoes 101: Doneness and Timing
Steak bites are small, so the difference between perfect and overcooked is only a minute or two. Because the pieces finish in the hot garlic butter, pull them from the pan a few degrees before your target temperature. Use this guide as a starting point.
| Doneness | Pull from pan at | Final temperature | Sear time per side |
|---|---|---|---|
| Medium-rare | 120 to 125°F (49 to 52°C) | 130 to 135°F (54 to 57°C) | About 1 minute |
| Medium | 130 to 135°F (54 to 57°C) | 140 to 145°F (60 to 63°C) | About 1½ minutes |
| Medium-well | 140 to 145°F (60 to 63°C) | 150 to 155°F (66 to 68°C) | About 2 minutes |
Most people prefer steak bites medium-rare to medium. If you like your steak more done, keep the pieces in a single layer and add a minute of searing rather than lowering the heat, so you keep the crust.
Why This Method Works
There are three small ideas behind this recipe. First, the potatoes go in the pan first because they take the longest, and their starch and the browned bits they leave behind build flavor for everything that follows. Second, the steak is seared at high heat for a short time, which creates the brown crust (the Maillard reaction) without overcooking the inside. Third, the butter and garlic go in at the end over lower heat, so they stay sweet and fragrant instead of burning. Each step builds on the last, and the pan does all of the work.
Tips for the Best Steak and Potatoes Skillet
- Dry everything. Dry steak and dry potatoes brown better and taste richer.
- Use a hot pan. The oil should shimmer before the potatoes go in and almost smoke before the steak goes in.
- Do not crowd the pan. Overcrowded food steams and turns gray. Sear the steak in two batches if you need to.
- Leave the food alone. Let the potatoes and steak sit until they release naturally from the pan. That is how you get a crust.
- Add the garlic last. It cooks in seconds and turns bitter if it burns.
- Cut the pieces evenly. Same-size cubes mean the steak cooks at the same rate.
- Finish with acid. A small squeeze of lemon juice cuts through the butter and wakes up the flavors.
Common Mistakes to Avoid
- Cooking cold steak. Straight from the fridge, the center stays raw while the outside overcooks. Let the steak sit for 15 minutes first.
- Overcooking the steak. Cubes are small and cook in minutes. Pull them while they are still slightly pink inside.
- Burning the garlic. Lower the heat before adding the butter and garlic.
- Skipping the lid for the potatoes. Covering the pan traps steam and cooks the potatoes through. Uncover at the end to crisp them.
- Using the wrong cut. Tough cuts like chuck will stay chewy. Choose sirloin, ribeye or strip.
- Stirring too much. Constant stirring prevents browning. Let each side sit and sear.

A Few Seasoning and Flavor Notes
The seasoning here is simple on purpose, because good steak and crispy potatoes do not need much. Salt and pepper bring out the beef, paprika adds a little warmth and color, and the herbs perfume the butter. If you like a stronger flavor, mix a spoonful of the garlic butter with a teaspoon of Worcestershire sauce or Dijon mustard at the end, or finish with a pinch of flaky sea salt right before serving. For a lighter dinner, use a little less butter and add extra vegetables to the pan. Every skillet is slightly different, so taste as you go and adjust the salt, garlic and lemon until it tastes right to you.
Variations and Ideas
- Ribeye steak and potatoes: Use ribeye for a richer, juicier version. Trim any big pieces of fat first.
- Sweet potatoes: Swap half or all of the potatoes for sweet potato cubes. Cook them a couple of minutes longer.
- Add vegetables: Toss in broccoli florets, green beans, asparagus or sliced bell peppers during the last 5 minutes of potato cooking.
- Make it spicy: Add extra red pepper flakes, a pinch of cayenne or a spoonful of hot honey at the end.
- Make it cheesy: Sprinkle with parmesan or a little shredded mozzarella and cover the pan for one minute so it melts.
- Cajun style: Season the steak and potatoes with Cajun seasoning instead of paprika.
- Mushrooms and onions: Sauté sliced mushrooms and onions in the pan after the steak for a classic steakhouse flavor.
Easy Substitutions
| Ingredient | Substitute |

- Green salad: A crisp salad with lemon vinaigrette is a bright contrast to the butter.
- Roasted or steamed vegetables: Broccoli, asparagus and green beans all work well.
- Garlic bread: Perfect for mopping up the leftover butter sauce.

Make-Ahead, Storage and Reheating
Make ahead: You can cube the steak and halve the potatoes up to a day in advance and store them separately in the fridge. Mince the garlic and chop the herbs ahead of time as well, so dinner comes together in minutes. Season the steak just before cooking.
Storing: Keep leftovers in an airtight container in the fridge for up to 3 days. Cool the food within 2 hours of cooking.
Reheating: Warm the skillet over medium heat, add a small pat of butter and heat the steak and potatoes for 3 to 4 minutes, stirring until hot. This brings back the crisp potatoes and keeps the steak tender. Avoid reheating in a microwave for long, since the steak can turn rubbery.
Freezing: This recipe is best fresh, because the potatoes lose their texture after freezing. If you want to freeze it, freeze the steak alone for up to 2 months and cook fresh potatoes when you reheat.
Cooking for a Crowd or Doubling the Recipe
If you need to feed six to eight people, do not simply double everything in one pan, because an overcrowded skillet steams the food. Instead, use two large skillets, or roast the potatoes on a sheet pan at 425°F (220°C) for 30 to 35 minutes while you sear the steak in batches on the stove. Toss everything together with the garlic butter at the end and serve it family style from a big platter.
Meal Prep Tips
This recipe makes a great lunch the next day. Divide leftovers into containers with some steamed broccoli or green beans, and reheat them in a skillet for the best texture. You can also prep the raw ingredients on Sunday: cube the steak, halve the potatoes and mix the garlic, herbs and butter into a simple compound butter. On a busy night, you only need to cook.
Frequently Asked Questions
What is the best cut of steak for garlic butter steak and potatoes?
Sirloin is the best all-around choice because it is tender, beefy and affordable. Ribeye is richer and more marbled, and New York strip also works well. Tenderloin (filet) is very tender but costs more and has less flavor. Avoid tough cuts like chuck or stew meat, since they need long, slow cooking and will turn chewy in a quick skillet recipe.
Do I need to parboil the potatoes first?
No. Baby or small potatoes cut into halves cook through in the skillet in about 12 to 15 minutes if you cover the pan for the first part of cooking. If you want a faster dinner or you are using larger potatoes cut into chunks, you can microwave them for 4 to 5 minutes first, then brown them in the pan.
How do I keep the steak bites from getting tough?
Use a hot pan, do not overcrowd it and sear the bites for only 2 to 3 minutes total. Cook them in batches if needed. Because the steak finishes cooking for a minute in the garlic butter at the end, pull it from the pan when it is still slightly pink in the center and it will be juicy rather than chewy.
Can I make this garlic butter steak and potatoes recipe in a regular skillet?
Yes. Cast iron holds heat best and gives the deepest crust, but a heavy stainless steel or carbon steel skillet works well too. A nonstick pan is the weakest option because it does not brown as well and should not be heated as high.
Why add the garlic at the end?
Garlic burns quickly, and burnt garlic tastes bitter. Adding it with the butter in the last 1 to 2 minutes over medium-low heat gives you a sweet, fragrant garlic butter sauce without any bitterness.
Can I use salted butter?
Yes, but reduce the added salt a little and taste before the final seasoning. Unsalted butter gives you more control over how salty the dish turns out, which is why it is used in this recipe.
How long do leftovers keep, and how do I reheat them?
Store leftovers in an airtight container in the fridge for up to 3 days. Reheat in a skillet over medium heat for 3 to 4 minutes with a small knob of butter, which keeps the steak tender and re-crisps the potatoes. Microwaving works in a pinch but softens the potatoes.
Final Thoughts
This garlic butter steak and potatoes skillet is proof that a great dinner does not have to be complicated. With a hot pan, a good cut of steak and a spoonful of garlic butter, you get crispy potatoes, juicy beef and a sauce you will want to scrape from the pan. It is quick, comforting and easy to adapt to your taste, so it is a recipe you will come back to again and again. Save it for your next busy weeknight and enjoy.
