Garlic Butter Steak Bites and Potatoes

Tender, caramelized steak bites and crispy, golden potatoes tossed in a rich garlic butter sauce. This easy one-pan dinner is packed with flavor and ready in 30 minutes!

Why This Recipe Works:

• Sequential cooking ensures both the steak and potatoes cook at their optimal temperatures without crowding.
• Searing the potatoes in rendered steak fat builds a deep, savory flavor foundation.
• Adding the garlic and butter at the very end prevents the milk solids from burning while coating everything in a rich glaze.

I still remember the evening I ruined a beautiful ribeye.

My kitchen filled with grey, acrid steam as the meat boiled in its own juices, leaving me with rubbery chunks that tasted like wet cardboard.

The physics of a crowded pan is unforgiving. When you crowd beef and potatoes together, the moisture released from the potatoes immediately drops the pan's thermal mass. This prevents the Maillard reaction, steaming your steak instead of searing it.

The simple fix is cooking them sequentially in a screaming-hot cast-iron skillet.

By letting the potatoes get incredibly crispy in the rendered beef fat first, you set the stage for searing the steak bites in a flash. Trust me on this one, your forearms might ache from shaking that heavy skillet, but the reward is a plate of caramelized, buttery perfection. If you prefer cooking a whole cut of beef rather than bites, check out our guide on Pan Seared Steak with Garlic Butter.

Ingredients

• 1.5 lbs sirloin steak or ribeye, cut into 1-inch cubes
• 1.5 lbs baby yellow potatoes, quartered
• 2 tbsp olive oil, divided
• 1.5 tsp Diamond Crystal kosher salt, divided
• 1 tsp freshly cracked black pepper
• 4 tbsp unsalted butter
• 6 cloves garlic, minced
• 1 tbsp fresh rosemary, finely chopped
• 2 tbsp fresh parsley, chopped

Directions

1. Pat the steak bites completely dry with paper towels. Season with 1 teaspoon of Diamond Crystal kosher salt and black pepper.
2. Heat one tablespoon of olive oil in a large cast-iron skillet over medium-high heat until shimmering. Add the quartered potatoes in a single layer.
3. Cook the potatoes undisturbed for 4-5 minutes to develop a golden crust. Stir and continue cooking for another 6-8 minutes until tender, then transfer them to a plate.
4. Wipe the skillet quickly, add the remaining olive oil, and crank the heat to high. Add the steak bites in a single, uncrowded layer, searing for 2 minutes per side without moving them to build a deep crust.
5. Reduce heat to medium-low. Return the potatoes to the skillet, then add the butter, minced garlic, and chopped rosemary.
6. Toss everything continuously for 1-2 minutes, spooning the melted garlic butter over the steak and potatoes until fragrant. Garnish with fresh parsley and serve immediately.

Notes

• I highly recommend using Diamond Crystal kosher salt; if you are using Morton's or fine table salt, cut the volume in half (use 3/4 teaspoon instead of 1.5 teaspoons) to avoid over-salting.
• Patting the steak dry is essential because surface moisture absorbs thermal energy to evaporate, which delays the Maillard reaction and prevents a proper crust from forming.
• Do not add the garlic and butter at the beginning of the sear; garlic contains sugars that burn easily at high heat, turning bitter, so always toss them in during the final minute of cooking.
• After a day in the fridge, the butter will solidify and the potatoes will lose their crispness, but they reheat beautifully in a hot skillet rather than the microwave.
• If you want a slower, hands-off approach, you can try our Slow Cooker Garlic Butter Beef Bites with Potatoes.
• If you love this flavor profile, you can apply the exact same garlic butter technique to seafood with our Garlic Butter Shrimp.

Serving Suggestions

To turn this hearty skillet into a complete feast, pair it with bright, contrasting sides that cut through the rich, buttery glaze.

• Serve alongside a crisp green salad tossed in a zesty Greek Lemon Vinaigrette to balance the richness of the beef.
• Pair with a side of roasted vegetables like asparagus or green beans for a wholesome plate.
• Offer a warm, crusty baguette to soak up every last drop of the garlic butter pooling at the bottom of the skillet.
• For a low-carb alternative to the potatoes, serve the steak bites over a bowl of hot cauliflower rice.

Storage and Reheating

Leftovers keep well in an airtight container for up to three days.

However, the microwave is the enemy of crispy potatoes and tender steak. It will turn your perfectly seared medium-rare steak bites into grey, rubbery pebbles and make the potatoes soggy.

Instead, reheat them in a hot, dry skillet over medium heat. Toss frequently until the butter melts and the potato skins crisp up again.

Ingredient Substitutes

If you need to swap out ingredients based on what is in your pantry, here are the best alternatives:

1. Steak: Swap sirloin for ribeye, New York strip, or even tenderloin. Avoid tough cuts like chuck unless you are using a slow cooker method.
2. Potatoes: Baby red potatoes or Yukon Golds work best. If you only have russets, peel them and cut them into smaller cubes so they cook through quickly.
3. Butter: You can use ghee or clarified butter, which has a higher smoke point and won't burn as easily.
4. Herbs: Fresh thyme or oregano can easily replace the rosemary.
