What Is Cowboy Butter?

Cowboy butter is a flavorful compound butter that elevates steaks and other dishes. It combines softened unsalted butter with a variety of savory ingredients.

Typical components include minced garlic, fresh herbs like parsley, chives, and thyme, as well as zesty additions such as lemon juice and zest. Many recipes incorporate Dijon mustard, Worcestershire sauce, and red pepper flakes for extra kick.

The mixture is usually seasoned with kosher salt and may include paprika for a smoky note. Some versions add finely chopped shallots for mild onion flavor.

To prepare cowboy butter, the ingredients are mixed into room temperature butter until well combined. The butter is then chilled to allow flavors to meld.

This versatile condiment can be melted over grilled steaks, used as a dipping sauce, or spread on bread. Its rich, herbaceous taste complements a variety of meats and sides.

Cowboy butter offers a convenient way to add complex flavor to dishes. Its blend of herbs, spices, and aromatics creates a bold taste that enhances the natural flavors of food.

Choosing the Right Cut

Selecting the ideal cut of beef is crucial for a delicious cowboy butter steak. The right choice balances tenderness, flavor, and affordability.

Flat Iron Steak Overview

Flat iron steak comes from the beef shoulder, specifically the top blade area. This cut stands out for its excellent marbling and tenderness. Flat iron steaks typically weigh between 8-12 ounces, making them perfect for individual servings.

The steak’s uniform thickness allows for even cooking. Its rich, beefy flavor pairs exceptionally well with cowboy butter. Flat iron steaks are relatively affordable compared to premium cuts, offering great value for their quality.

Alternative Steak Options

While flat iron steak is ideal, other cuts can work well with cowboy butter. Ribeye offers intense marbling and flavor but comes at a higher price point. NY strip provides a good balance of tenderness and beefy taste.

Flank steak is a leaner option that benefits from the added richness of cowboy butter. It requires careful slicing against the grain for optimal tenderness. For budget-conscious cooks, sirloin can be a suitable alternative, though it may not be as tender as flat iron.

Preparation Essentials

Proper preparation is key to achieving a delicious cowboy butter flat iron steak. Seasoning, marinating, and monitoring temperature are crucial steps in the process.

Marinades and Seasoning

Flat iron steak benefits from marinades and seasoning to enhance flavor and tenderness. A simple marinade of olive oil, minced garlic, and spices like chipotle powder can elevate the taste profile. For a quick seasoning, create a rub using salt, pepper, and paprika.

Allow the steak to marinate for at least 30 minutes, or up to 4 hours for deeper flavor penetration. Pat the steak dry before cooking to ensure a good sear.

For cowboy butter, combine softened butter with herbs, garlic, and lemon juice. Chill the mixture until firm to serve as a flavorful dipping sauce.

Meat Thermometer Usage

A meat thermometer is essential for achieving the desired doneness. Insert the thermometer into the thickest part of the steak to accurately measure the internal temperature.

For medium-rare, aim for 130-135°F (54-57°C). Medium is 140-145°F (60-63°C), while medium-well is 150-155°F (66-68°C).

Remove the steak from heat when it’s 5°F below the target temperature. The internal temperature will continue to rise during resting.

Let the steak rest for 5-10 minutes before slicing. This allows juices to redistribute, ensuring a juicy and flavorful result.

Cooking Techniques

Mastering the right cooking techniques is crucial for creating a delicious cowboy butter flat iron steak. The methods below focus on achieving the perfect doneness and developing rich flavors.

Grilling the Perfect Steak

Grilling imparts a smoky flavor and beautiful grill marks to flat iron steak. Preheat the grill to high heat, around 450-500°F. Pat the steak dry and season generously with salt and pepper. Place the steak on the hot grates and grill for 4-5 minutes per side for medium-rare. Use tongs to flip the steak, avoiding piercing the meat with a fork.

For even cooking, rotate the steak 45 degrees halfway through grilling each side. This creates appealing crosshatch grill marks. Let the steak rest for 5-10 minutes after grilling to allow juices to redistribute.

Searing for a Golden Crust

Searing creates a flavorful, golden-brown crust on the steak’s exterior. Heat a heavy-bottomed pan or skillet over high heat until very hot. Add a small amount of high-smoke point oil like vegetable or grapeseed oil.

Pat the steak dry to remove moisture, which helps achieve a better sear. Place the steak in the hot pan and cook for 3-4 minutes without moving it. Flip and sear the other side for an additional 3-4 minutes for medium-rare.

Using a Cast Iron Skillet

A cast iron skillet is ideal for cooking flat iron steak due to its heat retention and distribution properties. Preheat the skillet in a 450°F oven for 20 minutes. Carefully remove the hot skillet and place it on a burner over high heat.

Add a thin layer of oil to the skillet. Sear the seasoned steak for 3-4 minutes per side. For medium-rare, finish cooking in the oven for 5-7 minutes. The skillet’s heat creates a beautiful crust while keeping the interior juicy and tender.

Final Touches

The final touches are crucial for achieving a perfect cowboy butter flat iron steak. Proper application of the cowboy butter and attaining the ideal doneness elevate the dish to new heights.

Applying Cowboy Butter

Cowboy butter adds a rich, flavorful finish to the flat iron steak. Slice the chilled cowboy butter into thin rounds. Place 1-2 rounds on top of the hot steak immediately after removing it from the grill or pan. The residual heat will melt the butter, creating a luscious sauce.

For extra indulgence, serve additional cowboy butter on the side. This allows diners to add more as desired. Some prefer to dip each bite of steak into the melted butter for maximum flavor impact.

Achieving Ideal Doneness

Using a meat thermometer ensures the flat iron steak reaches the perfect internal temperature. For medium-rare, aim for 130-135°F (54-57°C). Medium doneness is achieved at 140-145°F (60-63°C).

Remove the steak from heat when it’s 5°F below the target temperature. Let it rest for 5-10 minutes. The internal temperature will continue to rise, reaching the desired doneness.

For optimal tenderness, slice the steak against the grain. This breaks up the muscle fibers, resulting in a more tender bite. Serve immediately with the melted cowboy butter for a mouthwatering experience.

Serving Suggestions

Enhance your cowboy butter flat iron steak with carefully chosen accompaniments and an appealing presentation. The right side dishes and plating techniques can elevate this flavorful cut to new heights.

Side Dishes

Roasted potatoes make an excellent pairing with cowboy butter flat iron steak. Toss quartered red potatoes with olive oil, salt, and rosemary before roasting until crispy. Grilled corn on the cob complements the steak’s smoky flavors. Brush with melted butter and sprinkle with chili powder for a zesty kick.

Fresh green beans sautéed with garlic and almonds offer a light, crunchy contrast. For a heartier option, serve creamy mashed potatoes infused with roasted garlic. A crisp garden salad with mixed greens, cherry tomatoes, and a tangy vinaigrette balances the rich flavors of the steak.

Consider offering extra cowboy butter as a dip for crusty bread or steamed vegetables. This versatile condiment adds depth to various side dishes.

Presentation Tips

Slice the flat iron steak against the grain into thin strips. Arrange these on a warm platter or individual plates. Drizzle with a spoonful of melted cowboy butter for added flavor and visual appeal.

Garnish the plate with fresh herbs like parsley or cilantro to add color and aroma. A sprig of rosemary or thyme can echo flavors used in marinating the steak. Place side dishes strategically around the steak to create an attractive, balanced plate.

For a rustic presentation, serve the steak on a wooden board with small bowls of sides. This family-style approach encourages sharing and creates a convivial atmosphere. Alternatively, use cast iron skillets for both cooking and serving to maintain heat and add a touch of cowboy authenticity.

Preservation and Reheating

Proper storage is crucial for maintaining the quality of leftover cowboy butter flat iron steak. Refrigerate the steak within two hours of cooking, wrapped tightly in plastic wrap or aluminum foil.

For longer storage, place the wrapped steak in an airtight container. It will keep in the refrigerator for 3-4 days. Freezing is an option for extended preservation, with a shelf life of up to 3 months.

When reheating, several methods can restore the steak’s flavor and texture. The oven method is reliable:

1. Preheat to 250°F (121°C)
2. Place steak on a wire rack over a baking sheet
3. Heat until internal temperature reaches 110°F (43°C), about 20-30 minutes

For a quicker option, try the air fryer:

• Preheat to 350°F (175°C)
• Cook for 3-5 minutes, checking temperature
• Aim for 145°F (63°C) internal temperature

To preserve moisture, add a pat of the cowboy butter during reheating. This helps maintain the steak’s rich flavor and juiciness.

Avoid microwaving, as it can lead to uneven heating and toughness. Regardless of method, be careful not to overcook the steak during reheating to maintain its original quality.
