Begin by selecting your preferred cut of steak, such as top sirloin or ribeye, and cut it into 1-inch bite-sized pieces. Generously season the steak bites with kosher salt, freshly ground black pepper, and chopped rosemary. Let the seasoned steak sit for about 15 minutes at room temperature to enhance its flavor and tenderness.

Heat a large skillet over medium-high heat and add a drizzle of olive oil. Once the oil is shimmering, carefully add the steak pieces in batches, ensuring not to overcrowd the pan. Sear the steak bites for about 1 minute on each side, or until they develop a beautiful brown crust. Remove the cooked steak and set it aside on a plate.

In the same skillet, reduce the heat to medium and add a generous amount of unsalted butter. Once the butter melts and begins to sizzle, add the minced garlic and red pepper flakes. Stir the mixture for about 30 seconds, or until fragrant, being careful not to let the garlic burn for an optimal garlic flavor to complement your Garlic Butter Steak Bites.

Return the seared steak bites to the skillet, making sure to coat each piece in the garlic butter sauce. Toss gently for another 2-3 minutes until the steak reaches your desired level of doneness, typically medium-rare to medium for maximum tenderness. The steak should be beautifully glistening and full of flavor from the rich butter and garlic.

Once cooked to perfection, transfer the Garlic Butter Steak Bites to a serving platter. For an extra touch of freshness, garnish with freshly chopped parsley. These savory bites pair beautifully over a bed of creamy mashed potatoes or alongside your favorite grilled vegetables, ready to wow your family and guests!
