Ingredients & Substitutions

Beef steak searing in a black cast-iron skillet, developing a dark browned crust. — Sear the steak undisturbed in a hot cast-iron skillet to achieve a deep, dark browned crust.

To achieve the perfect seared beef steak slices and that iconic melted golden butter sauce, you will need a mix of high-quality protein and vibrant aromatics.

The Steak

Beef Steak (Ribeye or NY Strip): You will need 2 thick-cut steaks, roughly 1.5 lbs (680g) total, about 1.5 inches (3.8cm) thick. The generous marbling in these cuts ensures a juicy, pink medium-rare center.

Neutral Oil: Use 2 tbsp (30ml) of canola, vegetable, or avocado oil. A high smoke-point oil is mandatory to achieve that dark browned crust without burning the pan.

Kosher Salt: Use 2 tsp (10g) of coarse kosher salt. Salting the meat draws out moisture for a better sear while enhancing the natural beefy flavor.

The Cowboy Butter Sauce

Unsalted Butter: You will need 1/2 cup (113g) of unsalted butter to create the glossy, melted golden butter sauce. Using unsalted allows you to control the final sodium level of the rich pan sauce.

Minced Garlic: Measure out 2 tbsp (30g) of freshly minced garlic. Fresh garlic infuses the golden butter sauce with a pungent, sweet, and nutty aroma.

Coarse Black Pepper: You need 1 tbsp (7g) of freshly cracked coarse black pepper. This adds a bold, woody heat that beautifully coats the exterior of the steak.

Crushed Red Pepper Flakes: Use 1 tsp (2g) of crushed red pepper flakes. These vibrant red flakes add a visible pop of color and a pleasant, lingering warmth to the melted butter.

Fresh Green Parsley: Finely chop 2 tbsp (8g) of fresh green parsley. The bright, grassy notes cut through the richness of the butter and provide a gorgeous visual contrast.

Thyme Leaves: Use 1 tsp (1g) of fresh thyme leaves, or a generous pinch. The earthy, floral notes of thyme perfectly complement the savory roasted beef.

Equipment Needed

Black Cast-Iron Skillet: Essential for retaining high heat, guaranteeing an aggressive, dark browned crust on your steak.
Meat Thermometer: The foolproof way to ensure a flawless pink medium-rare center (aiming for 130°F / 54°C).
Heavy-Duty Tongs: Crucial for flipping the steaks safely and searing the fat caps.

Step-by-Step Instructions

Step 1: Prep and Season the Steak

Remove your steaks from the refrigerator 30 minutes before cooking to remove the chill. Pat the steaks completely dry with paper towels; moisture is the enemy of a good sear. Season them generously on all sides with kosher salt and half of your coarse black pepper.

Step 2: Sear to a Dark Browned Crust

Place your black cast-iron skillet over medium-high heat and add the neutral oil. Once the oil is shimmering and just beginning to smoke, carefully lay the steaks in the pan away from you. Sear undisturbed for 3 to 4 minutes per side until a deep, dark browned crust forms.

Step 3: Rest and Slice

Remove the steaks from the skillet and transfer them to a cutting board to rest for 5 to 10 minutes. Resting is essential so the juices redistribute, ensuring a perfectly pink medium-rare center. Once rested, slice the steak against the grain into thick, even strips.

Step 4: Create the Cowboy Butter Sauce

While the steak rests, wipe out the excess burnt oil from the black cast-iron skillet, but leave the browned bits (fond) behind. Lower the heat to medium-low and add your unsalted butter. As it melts into a golden liquid, stir in the minced garlic, crushed red pepper flakes, and the remaining coarse black pepper, cooking for 1 minute until fragrant.

Step 5: Coat and Serve

Remove the skillet from the heat and stir in the chopped fresh green parsley and a pinch of thyme leaves. Carefully arrange your seared beef steak slices back into the warm skillet. Toss the meat so it is generously coated in the glossy sauce, letting the melted butter sauce pool around the base of the steak pieces.

Expert Tips for Success

Dry the meat thoroughly: Always pat your beef completely dry before searing. Any surface moisture will create steam, preventing that beautiful dark browned crust.
Watch the temperature: Pull your steaks off the heat when they reach 125°F (51°C). The internal temperature will rise to 130°F (54°C) as they rest, yielding a perfect pink medium-rare center.
Don’t burn the garlic: When making your golden butter sauce, keep the heat low. Burnt garlic will turn the glossy butter bitter and ruin the flavor profile.
Slice against the grain: For the most tender bite, identify the direction of the muscle fibers and slice perpendicular to them.

Storage & Reheating/Freezing

Store leftover sliced steak and the cooled cowboy butter sauce in an airtight container in the refrigerator for up to 3 days. The butter will solidify in the fridge but will melt beautifully when reheated.

To reheat without overcooking that pink medium-rare center, place the steak slices and butter in a skillet over low heat just until warmed through. Freezing is not recommended, as the freezing process can alter the texture of the seared beef and cause the butter sauce to separate upon thawing.

What to Serve With This

This rich and savory steak requires sides that can soak up every drop of that melted golden butter sauce. For a classic steakhouse feel, serve it alongside Creamy Mashed Potatoes or Baked Garlic Butter Potatoes.

If you prefer a lighter, vegetable-forward pairing, Crispy Baked Cauliflower Steaks and Hot Honey Roasted Carrots offer a fantastic textural contrast. For a fresh, crunchy element to cut through the richness of the butter, a crisp Asian Cabbage Salad makes a surprisingly vibrant side dish.

Ribeye and New York Strip are the best choices. Their generous marbling renders beautifully during a high-heat cast-iron sear, creating a dark browned crust and tender medium-rare center.

How do I get a dark browned crust without overcooking the inside?

Pat the steak completely dry with paper towels before seasoning, and use a heavy black cast-iron skillet preheated until smoking. Sear quickly over medium-high heat, then let the steak rest.
