How to Make Cowboy Butter Steak Frites Sandwich
Preparing the Fries and Onions
Preheat your oven to 425°F (220°C).
Wash and cut the russet potato into thin fries. Toss the fries with olive oil, salt, and pepper. Spread them on a baking sheet in a single layer.
Bake for 25 to 30 minutes, turning halfway through cooking. Continue baking until golden brown and crisp.
Meanwhile, melt 2 tablespoons butter in a skillet over medium heat. Add the sliced red onions and cook slowly for about 20 minutes. Stir occasionally until the onions become soft, sweet, and caramelized.
While the onions cook, prepare the cowboy butter by combining melted butter, garlic, parsley, Dijon mustard, lemon juice, paprika, red pepper flakes, salt, and pepper in a small bowl. Mix thoroughly and set aside.
Cooking the Steak and Building the Sandwich
Remove the ribeye steak from the refrigerator about 30 minutes before cooking.
Season generously with salt and pepper.
Heat a cast iron skillet over high heat until very hot. Cook the steak for approximately 4 to 5 minutes per side for medium-rare, adjusting as needed for preferred doneness.
Transfer the steak to a cutting board and let it rest for at least 10 minutes. This step allows the juices to redistribute throughout the meat.
Slice the steak thinly against the grain.
Toast the ciabatta rolls lightly until golden.
Spread cowboy butter onto both sides of each roll. Layer the caramelized onions on the bottom half, followed by sliced steak. Top with crispy fries and drizzle additional cowboy butter over everything.
Place the top bun on the sandwich and serve immediately.
Tips for the Best Results
Choosing the Right Steak
Ribeye remains the preferred choice because of its excellent marbling and flavor. However, New York strip steak or sirloin can also work well.
Always allow the steak to reach room temperature before cooking. This simple step encourages more even cooking throughout the meat.
Furthermore, resting the steak after cooking is essential. Skipping this step can result in juices running out instead of staying inside the meat.
Making the Perfect Cowboy Butter
Fresh ingredients create the best cowboy butter. Fresh parsley and freshly minced garlic deliver brighter flavor than dried alternatives.
If you enjoy extra heat, increase the amount of crushed red pepper flakes. On the other hand, reducing the spice creates a milder version suitable for all ages.
Cowboy butter can also serve as a dipping sauce for fries or vegetables. Therefore, consider making extra for serving alongside the sandwiches.
Serving Ideas and Storage
What to Serve with Cowboy Butter Steak Frites Sandwich
Although the sandwich is filling on its own, several side dishes complement it beautifully:
- Coleslaw
- Pickle spears
- Potato salad
- Garden salad
- Roasted vegetables
Additionally, extra cowboy butter makes an excellent dipping sauce for both fries and bread.
Storage Tips
For best results, enjoy the sandwich immediately after assembly.
Store leftover steak separately in an airtight container in the refrigerator for up to 3 days.
Keep fries and bread separate to maintain their texture. Reheat steak gently before rebuilding the sandwich.
Cowboy butter can be refrigerated for up to 5 days and reheated gently when needed.
