Prepare the Steak: Start by patting the beef cubes dry with paper towels. This step is crucial for achieving a good sear that locks in the juices. Season generously with salt and pepper on all sides, ensuring that every piece is well-coated for maximum flavor. A good sear not only enhances flavor but also gives the steak bites a beautiful golden crust. For the best results, let the seasoned steak rest for about 15 minutes to bring them to room temperature before cooking.
Heat the Pan: In a large skillet, heat 1 tablespoon of olive oil over medium-high heat. Wait until the oil shimmers, indicating it's hot enough for a good sear; this is key for caramelizing the surface of the steak bites. A hot pan will help create that desirable crust, which adds texture and flavor. To test if the pan is hot enough, you can flick a drop of water into the pan; if it sizzles and evaporates quickly, you’re ready.
Sear the Steak: Add the beef cubes to the skillet in a single layer. Avoid overcrowding the pan, as this can cause steaming instead of searing and will lead to a less appealing texture. Cook for about 2-3 minutes on each side until browned and cooked to your desired doneness. For medium-rare, aim for an internal temperature of 130°F (54°C); use a meat thermometer for accuracy, as it ensures perfect cooking every time. If you prefer more char, you can cook them slightly longer, but be cautious not to overcook.
Make the Garlic Butter: While the steak is cooking, prepare the garlic butter. In a small bowl, combine the melted butter, minced garlic, chopped parsley, and lemon juice if using. Mix well until everything is combined; the garlic will infuse its flavor into the butter, creating a luxurious sauce that you will want to drizzle over everything. Allowing the garlic to sit in the butter for a couple of minutes before mixing can deepen the flavor further, allowing its aroma to permeate the butter.
Combine: Once the steak bites are cooked, remove them from the skillet and place them in a large bowl. Pour the garlic butter mixture over the steak bites, tossing gently to coat all the pieces evenly with the rich sauce. This step allows the flavors to meld beautifully, ensuring each bite is bursting with delicious garlic butter flavor. Make sure to scrape up any browned bits from the bottom of the pan; these add wonderful flavor to the sauce.
Serve: Transfer the steak bites to a serving platter. Drizzle any remaining garlic butter from the bowl over the top for added flavor. Garnish with extra parsley if desired for a pop of color, and serve immediately to enjoy the dish at its best. Pairing with toothpicks can make these bites even more user-friendly for gatherings. Consider serving alongside a simple salad or roasted vegetables to balance the richness of the steak.
