Garlic Butter Steak Bites & Potatoes

I make garlic butter steak bites and potatoes on the nights I want steak-and-potatoes energy without actually cooking a whole steak. Dice it up, marinate it while the potatoes go in the air fryer, sear it hot and fast, finish it in butter and garlic. Dinner’s on the table in under 30 minutes and it doesn’t taste like a shortcut.

Why This Works

Cutting the steak into 1–1½ inch pieces instead of cooking it whole changes the whole equation. Small pieces sear on more sides in less time, so you get that browned, salty crust on nearly every surface instead of just the top and bottom of a steak.

The order matters more than it looks like it should. Marinating the steak in soy sauce, onion powder, garlic powder, and black pepper before it hits the pan means the seasoning has time to actually get into the meat instead of just sitting on the surface — soy sauce also helps the outside brown faster because of the sugar and salt content. Air frying the potatoes separately, instead of trying to cook everything in one pan, keeps them crisp. Potatoes release a lot of moisture as they cook; steam them next to the steak and neither one browns properly.

Ingredients

• 2 pounds steak (ribeye, NY strip, or sirloin), diced into 1–1½ inch pieces
• 2 tablespoons soy sauce
• 1 teaspoon onion powder
• 1 teaspoon garlic powder
• ¼ teaspoon black pepper
• Olive oil
• 2 large russet potatoes, diced into 1-inch pieces
• 1 tablespoon seasoned salt
• 6 tablespoons butter
• 1 tablespoon minced garlic

Instructions

1. Dice the steak into 1–1½ inch pieces.
2. Place the steak bites in a large mixing bowl and add 1 teaspoon olive oil, soy sauce, onion powder, garlic powder, and black pepper.
3. Toss until every piece is coated, then set aside to marinate for 15–30 minutes.
4. While the steak marinates, wash and peel the potatoes and dice them into 1-inch pieces.
5. Rinse the diced potatoes under cold water, then pat them dry with a paper towel — this is what gets them crispy instead of soft, so don’t skip it.
6. Place the potatoes in a small bowl, drizzle with 1 teaspoon olive oil, and season with seasoned salt. Toss until coated.
7. Preheat the air fryer to 400°F and add the potatoes in a single layer.
8. Cook for 15–20 minutes, tossing every 5 minutes, until fork tender and golden at the edges.
9. While the potatoes finish, heat a large skillet — cast iron if you have it — over medium-high heat.
10. Add the marinated steak bites in a single layer, working in batches if needed so the pan isn’t crowded. Cook for 2–3 minutes without moving them, then flip.
11. Cook another 1–2 minutes for medium-rare, longer if you like it more done. Push the steak to one side of the skillet.
12. Add the butter and minced garlic to the cleared side of the pan. Once the butter melts and the garlic turns fragrant (about 30 seconds), tilt the pan and spoon the garlic butter over the steak bites for another minute.
13. Plate the steak bites over the crispy potatoes and spoon any extra garlic butter from the pan on top.

Note: the original recipe didn’t specify when to add the butter and minced garlic — I’ve built that step in as a garlic-butter baste at the end, which is the standard way to do it without breaking the sear. Swap in the real method if it was done differently.

Prep Time & Servings

• Prep time: 10 minutes
• Cook time: 20 minutes
• Total time: about 30 minutes
• Serves: 4
• Equipment: air fryer, large skillet (cast iron preferred)

Tips

• Pat the potatoes fully dry before seasoning — any leftover water turns to steam in the air fryer and keeps them from crisping.
• Don’t crowd the skillet with steak.
• Let the steak actually sit untouched for the first 2–3 minutes. Moving it too early is the most common reason it doesn’t brown.
• Ribeye brings more marbling and a richer bite; sirloin is leaner and cooks a touch faster.

Variations

• Swap the potatoes for baby yukons if that’s what’s in the fridge — same timing, slightly creamier inside.
• Add a squeeze of lemon over the finished steak if you want to cut the richness of the butter.
• Skip trying to cook this in one skillet start to finish.

Make-Ahead

The steak can marinate up to a day ahead in the fridge, covered — any longer and the soy sauce starts to break down the texture instead of just seasoning it. Don’t dice and season the potatoes ahead of time; they’ll oxidize and turn gray, and the seasoned salt draws out moisture that keeps them from crisping later. Reheated steak bites lose their sear no matter what — a hot skillet for 60–90 seconds gets them closer than a microwave, but they won’t be quite what they were fresh.

Closing Thoughts

This is one of those recipes that scales up easily if you’re feeding more than four — just work the steak in batches so the skillet never gets crowded.
