Ingredients

  

For the Steak:

• 2 ribeye or New York strip steaks about 1 to 1 1/4 inches thick
• 1 tablespoon olive oil
• 1 teaspoon kosher salt
• 3/4 teaspoon black pepper
• 1/2 teaspoon garlic powder
• 1 tablespoon butter

For the Cowboy Butter:

• 6 tablespoons unsalted butter softened
• 3 garlic cloves minced
• 1 tablespoon Dijon mustard
• 1 tablespoon fresh lemon juice
• 1 teaspoon lemon zest
• 2 tablespoons fresh parsley finely chopped
• 1 tablespoon fresh chives finely chopped
• 1/2 teaspoon smoked paprika
• 1/4 teaspoon red pepper flakes
• 1/4 teaspoon black pepper
• Pinch of salt

For the Crispy Smashed Potatoes:

• 1 1/2 pounds baby potatoes
• 2 tablespoons olive oil
• 1/2 teaspoon garlic powder
• 1/2 teaspoon salt
• 1/4 teaspoon black pepper
• 1 tablespoon fresh parsley chopped

Method

 

1. Preheat the oven to 425°F (220°C). Place the baby potatoes in a pot, cover with cold salted water, and bring to a boil. Cook for 15 to 18 minutes, until fork-tender. Drain and let them steam dry for about 5 minutes.
2. Arrange the potatoes on a parchment-lined baking sheet. Press each one flat with the bottom of a glass or measuring cup until about 1/2 inch thick. Drizzle with the olive oil and sprinkle with the garlic powder, salt, and black pepper.
3. Roast for 20 to 25 minutes, until deeply golden and crisp at the edges. For extra crispness, broil for 1 to 2 minutes at the end, watching closely. Sprinkle with fresh parsley.
4. Make the cowboy butter: stir together the softened butter, garlic, Dijon mustard, lemon juice, lemon zest, parsley, chives, smoked paprika, red pepper flakes, black pepper, and a pinch of salt until smooth and well combined. Adjust the seasoning to taste and set aside at room temperature.
5. Take the steaks out of the fridge 20 to 30 minutes before cooking. Pat them very dry with paper towels and season all over with the kosher salt, black pepper, and garlic powder.
6. Heat a heavy skillet (cast iron is best) over medium-high to high heat until very hot, then add the olive oil.
7. Sear the steaks for 3 to 4 minutes without moving them, until a deep crust forms. Flip and cook 2 to 4 minutes more. During the last minute, add the butter and tilt the pan to baste the steaks with the foaming butter.
8. Check the internal temperature with a meat thermometer: Rare 120-125°F, Medium-rare 125-130°F, Medium 135-140°F, Medium-well 145-150°F. Remember the temperature will rise as the steak rests; medium-rare to medium gives the best texture.
9. Transfer the steaks to a plate, spoon a little cowboy butter over the top, and rest for 5 to 10 minutes without covering tightly.
10. Slice the steak against the grain and arrange it on plates with the crispy smashed potatoes. Spoon melted cowboy butter over everything, finish with cracked black pepper and fresh parsley, and serve immediately.

Tips from Chef Lea

• I dry the steak thoroughly. Surface moisture creates steam and prevents proper browning, so I pat the steak very dry with paper towels before it goes anywhere near the pan.
• I use a properly hot skillet. The pan is already hot when the steak goes in — that’s what gives us the deep, even crust.
• I don’t flip the steak constantly. I give the first side enough uninterrupted cooking time to develop its crust before I turn it once.
• I trust a thermometer, not the clock. It’s far more reliable than judging doneness by time alone, and it’s how I land on medium-rare to medium every time.
• I always let the steak rest. Cutting into it immediately lets more of the juices escape, so I give it 5 to 10 minutes first.
• I don’t drown the steak in cowboy butter. The butter should enhance the steak rather than hide its crust — a generous spoonful over the hot slices is plenty.

Variations

• Spicy Cowboy Butter Steak: Increase the red pepper flakes to 1/2 teaspoon and add a pinch of cayenne pepper.
• Cowboy Butter Steak Bites: Cut sirloin into large cubes before cooking. Sear quickly over high heat and toss with a small amount of cowboy butter just before serving.
• Cowboy Butter Chicken: Use chicken breasts or boneless chicken thighs instead of steak. Cook chicken to an internal temperature of 165°F (74°C).
• Steak Without Potatoes: Serve it with roasted asparagus, green beans, broccoli, a simple green salad, or grilled vegetables.

Make Ahead & Storage

Make ahead: The cowboy butter can be prepared up to 3 days ahead and refrigerated in an airtight container. Let it soften slightly before serving.

Fridge: Store leftover steak and potatoes in separate airtight containers in the refrigerator for up to 3 days. Store leftover cowboy butter separately in the refrigerator for up to 5 days.

Reheating: Reheat the steak gently in a skillet over low heat just until warmed through — avoid prolonged reheating, because it will continue cooking the center. Reheat the smashed potatoes in a 400°F (200°C) oven or air fryer until hot and crispy again, and add fresh cowboy butter after reheating.

FAQ

What cut of steak is best for cowboy butter?

Ribeye is particularly good because its rich beef flavor pairs beautifully with garlic-herb butter. New York strip and sirloin also work well.

Can I make cowboy butter ahead of time?

Yes. Prepare it up to 3 days ahead and refrigerate it in an airtight container. Let it soften slightly before serving.

Can I cook the steak on the grill?

Absolutely. Grill it over high heat to your preferred internal temperature, let it rest, then finish with cowboy butter.

Why isn’t my steak getting a good crust?

The steak or pan may be too wet or the skillet may not be hot enough. Pat the meat thoroughly dry and preheat the skillet before cooking.

Is cowboy butter spicy?

Only slightly with this recipe. You can omit the red pepper flakes for a mild version or increase them for more heat.
