Garlic Butter Steak Bites and Potatoes is a dish that delivers everything I crave in a hearty dinner. Juicy cubes of sirloin get that golden crust while bite-size potatoes soak up loads of savory garlic butter. This skillet supper comes together quickly and fills the kitchen with a mouthwatering aroma every time. When my family is hungry but we do not want to fuss, these steak bites are my weeknight hero.
The first time I threw this together, everyone hovered around the stove sneaking nibbles. It instantly went on our regular dinner rotation and no one ever gets tired of it.
Ingredients
- Olive oil: provides the initial flavor base and gives a little crispness to potatoes and steak. Choose extra-virgin for the richest taste
- Unsalted butter: melts into the pan for that signature velvety garlic sauce. Go for high quality and use it divided so the flavors layer
- Yukon Gold potatoes: hold their shape well when diced. Their creamy texture and golden color are perfect here. Pick ones that are firm and without any green tinges
- Garlic: is essential for the dish’s deep flavor. Use fresh cloves and mince them yourself for the best punch
- Dried rosemary and dried oregano: each add herbal notes to cut through the richness. They keep well in the pantry so you can whip this up anytime
- Kosher salt: brings out every ingredient’s flavor. The coarse grains are great for seasoning proteins
- Ground pepper: gives a background warmth and slight spice. Use freshly cracked if possible for stronger aroma
- Sirloin steak: is ideal for tender bite-sized pieces. Look for marbling and deep red color. Cube it just before cooking for the freshest result
- Freshly chopped parsley: is optional but really lifts the dish visually and adds a gentle hit of freshness. Always choose flat-leaf parsley if you can find it
Instructions
- Heat the Skillet:
- Start by heating a cast iron skillet over medium-high heat. Pour in the olive oil followed by two tablespoons of butter. Let the butter melt completely until bubbling but not browned. This step lays the foundation for rich flavor.
- Cook the Potatoes:
- Add diced Yukon Gold potatoes right into the hot fat with minced garlic dried rosemary dried oregano salt and pepper. Leave them undisturbed for about four minutes so a crispy crust forms. Then stir the potatoes and let them cook another three to four minutes until easily pierced with a fork. Remove all the potatoes and set aside so they do not overcook.
- Cook the Steak:
- Place the empty skillet back on the stove and turn the heat up to high. Drop in the remaining two tablespoons of butter and allow it to melt and bubble. Add the sirloin steak bites in an even layer. Cook the steak pieces for one minute before flipping or stirring them. Let them go for another one to two minutes depending on how rare or well done you prefer. Remove the skillet from the heat once the steak is just right.
- Combine and Serve:
- Scoop the cooked potatoes back into the skillet. Toss everything really well so the steak and potatoes are both coated in the residual garlic butter. Taste and adjust seasoning if needed. Finish everything with a sprinkle of freshly chopped parsley. Serve immediately and enjoy

Potatoes are my personal favorite part of this dish. Once they soak up the garlicky butter and all the steak juices they become little golden bites you cannot stop eating. My kids used to argue over who got the crispiest ones and now ask for double potatoes each time.
Storage Tips
Transfer any leftovers to a tight container and refrigerate for up to three days. When reheating use a skillet over medium heat and add a splash of water or more butter to keep everything moist. Avoid the microwave if possible as it can make steak chewy and potatoes soggy.
Ingredient Substitutions
Try russet or red potatoes if Yukon Golds are not available. For the steak you can swap in New York strip or even chicken breast if needed. If you love more heat add a pinch of chili flakes or a dash of smoked paprika to the butter.
Serving Suggestions
This meal is hearty enough on its own but pairs nicely with a simple green salad or roasted broccoli. I sometimes serve it with crusty bread to mop up any extra garlic butter. You can also drizzle lemon juice over the final skillet for brightness.
