Blackstone Steak Bites (Garlic Butter, 10 Minutes)

Steak bites are the fastest way to get a real steak dinner off a Blackstone. Bite-sized cubes of sirloin hit a ripping-hot surface, build a crust on every side in minutes, and finish in a pool of melted garlic butter. Because each cube gets direct steel contact — something a pan can’t give you at this quantity without crowding — every piece comes off with the sear you normally only get on the outside edge of a whole steak.

The whole cook takes about 8 minutes. It’s a weeknight dinner over rice or potatoes, a party appetizer straight off the griddle with toothpicks, or the protein for a steakhouse-style bowl.

Ingredients

• 1½ lbs top sirloin, cut into 1-inch cubes (ribeye or strip work too)
• 1 tbsp avocado oil or other high smoke point oil
• 1 tsp kosher salt
• ½ tsp black pepper
• ½ tsp garlic powder
• 3 tbsp butter
• 3 cloves garlic, minced
• Fresh parsley, chopped, to finish

You can also swap the butter and minced garlic for 2 tablespoons of make-ahead Blackstone garlic butter — same result, zero mid-cook chopping.

Instructions

Step 1: Cut and dry the steak

Cut the sirloin into even 1-inch cubes — uniform size means uniform doneness. Pat the cubes completely dry with paper towels, then season with salt, pepper, and garlic powder. Dry meat sears; wet meat steams.

Step 2: Preheat the griddle

Set the Blackstone to high and let it preheat a full 10 minutes. You want 450–500°F — the same searing range as a whole steak. If the surface isn’t hot enough, the cubes cook through before a crust forms.

Step 3: Sear without touching

Add the oil, spread it, and lay the cubes down in a single layer with space between them. Do not crowd them and do not move them. Let them sear untouched for 2 minutes until the bottom is deeply browned.

Step 4: Toss and finish searing

Flip or toss the cubes and sear another 2–3 minutes, turning once more so at least three sides get color. For medium-rare, pull when the interior reads 125–130°F on an instant-read thermometer — the cubes carry over a few degrees off the heat.

Step 5: Garlic butter finish

Move the bites to a cooler zone (or drop the burner to medium). Add the butter and minced garlic and toss constantly for 60–90 seconds until every cube is coated and the garlic is fragrant but not browned. Garlic burns fast at searing temperatures — this is why it goes in at the end, not the start.

Step 6: Rest and serve

Pull the bites, hit them with chopped parsley, and let them sit 2–3 minutes before serving. Serve over crispy potatoes, rice, or straight off the board with toothpicks.

Tips

Don’t crowd the surface. This is the difference between steak bites and gray boiled beef cubes. Each piece needs steel contact and airflow. If your griddle zone is small, cook in two batches — the second batch takes 4 minutes.

Sirloin is the right cut. It’s beefy, tender enough at medium-rare, and half the price of ribeye. Ribeye works if you want richer bites; avoid stew meat — it’s cut from tough muscles that need braising, not searing.

Keep the cubes big. 1-inch minimum. Smaller cubes overshoot medium-rare before the crust develops.

The garlic goes in last. Raw garlic added at the start of a 500°F sear turns bitter and black. Butter and garlic in the final 90 seconds gives you the flavor without the burn.

Frequently Asked Questions

What’s the best cut of steak for steak bites on a Blackstone?

Top sirloin is the best balance of flavor, tenderness, and price. Ribeye gives richer, fattier bites. New York strip also works well. Avoid pre-cut “stew meat” — it comes from tough cuts that need slow cooking and will be chewy off a griddle.

What temperature do you cook steak bites on a Blackstone griddle?

450–500°F — high heat. Steak bites need a fast, hard sear so the crust forms before the center overcooks. Preheat a full 10 minutes and cook the bites for 4–5 minutes total, pulling at 125–130°F internal for medium-rare.

Why are my steak bites tough or gray?

Three common causes: the griddle wasn’t hot enough, the surface was overcrowded (the cubes steamed in their own moisture instead of searing), or the cubes were cut too small and overcooked. Use 1-inch cubes, a 450°F+ surface, and space between every piece.

Can I marinate steak bites before cooking?

You can, but pat them very dry before they hit the griddle — surface moisture kills the sear. A dry rub of salt, pepper, and garlic powder plus the garlic butter finish gives you more crust than a wet marinade.
