Begin by cutting your sirloin steak or ribeye into 1-inch cubes, ensuring even cooking. Pat the steak pieces dry with paper towels, then season generously with salt and black pepper. Let the seasoned steak bites sit at room temperature for about 15 minutes.

In a large cast-iron skillet, heat 2 tablespoons of olive oil over medium-high heat until it shimmers but doesn’t smoke, approximately 2 minutes. Swirl the oil to coat the skillet evenly before proceeding.

Carefully add the steak cubes to the skillet in a single layer, ensuring they aren’t overcrowded. Sear for 2-3 minutes without moving them until they develop a beautiful golden-brown crust. Flip the steak bites and sear the other side for an additional 2-3 minutes. Once browned and cooked to medium-rare, transfer the steak bites to a plate and cover to keep warm.

Lower the heat to medium and return the skillet to the stove. Add 3 tablespoons of unsalted butter and 4 minced garlic cloves to the skillet, stirring gently. Sauté for about 30 seconds until fragrant and the garlic turns golden but not burnt.

Return the seared steak bites to the skillet and toss them in the garlic butter, making sure every piece is well-coated. Cook for an additional minute to meld the flavors, then garnish with chopped fresh parsley if desired.

Serve your Garlic Butter Steak Bites immediately for the best flavor and presentation, and enjoy every succulent bite!
