Bottom Line Up Front (Quick Answer):
To make 15-minute garlic butter steak bites, cut 1.25 lbs top sirloin or ribeye steak into 1-inch cubes and pat thoroughly dry with paper towels. Season with 1 tsp salt, 1/2 tsp black pepper, and 1/2 tsp garlic powder. Heat 1 tbsp avocado oil in a large cast-iron skillet over smoking high heat. Add steak in a single layer without crowding; sear undisturbed for 2 minutes, then flip for 2 more minutes until crusty (medium-rare). Toss in 3 tbsp butter, 4 smashed garlic cloves, 1 lb trimmed asparagus tips, and 1 sprig fresh rosemary, basting continuously for 2 minutes.
Why This Recipe Conquers Weeknights
- Blazing Cast-Iron Maillard Reaction: High-heat cast iron browns steak cubes in 2 minutes per side without overcooking the juicy pink center.
- Herb Butter Basting Finish: Basting hot steak bites with foaming butter, smashed garlic, and fresh rosemary infuses deep steakhouse aromatics in 60 seconds.
- Quick Skillet Asparagus Pairing: Tender asparagus tips sear in the residual beef drippings and herb butter in under 3 minutes, completing a low-carb dinner in one pan.

15-Minute Tender Garlic Butter Sirloin Steak Bites with Asparagus
Tested and approved by Elena Bennett • Serves 4
Ingredients
Step-by-Step Instructions
- Dry & Season Steak Cubes: Pat steak cubes thoroughly dry with paper towels (moisture prevents a crust). Season on all sides with salt, cracked black pepper, garlic powder, and onion powder.
- Blister-Sear Asparagus: Heat 1 tbsp oil in a large cast-iron skillet over high heat until smoking hot. Add trimmed asparagus spears and cook for 2 to 3 minutes, tossing occasionally until bright green and charred in spots. Transfer asparagus to a plate.
- Hard Sear Steak Bites: Add steak cubes to the smoking hot cast iron in a single layer (do not crowd the pan; cook in two batches if needed). Sear undisturbed for 2 minutes until deeply caramelized and brown. Flip cubes with tongs and sear 1.5 to 2 minutes more for medium-rare.
- Garlic Herb Butter Basting: Reduce heat to medium. Drop in 3 tbsp butter, minced garlic, and fresh rosemary into the pan. As butter foams, tilt the skillet and spoon the bubbling garlic herb butter continuously over the steak bites for 60 seconds.
- Toss Together & Plate: Return charred asparagus back into the skillet to reheat in the garlic butter for 30 seconds. Garnish with chopped fresh parsley and flaky sea salt. Serve immediately with lemon wedges!

Elena’s Chef Pro-Tip
Chef Secret:
Never crowd your steak cubes in the skillet! If the meat touches, moisture gets trapped between cubes and steams the beef gray instead of searing a dark mahogany crust. If your skillet is under 12 inches, sear the steak in two quick 3-minute batches.
