If you’re looking for a next-level sandwich that feels indulgent but comes together easily, these Cheesesteak Croissants with Cowboy Butter deliver every time. Think buttery, flaky croissants, filled with seasoned grilled steak, melty mozzarella, and a drizzle of garlic-herb cowboy butter that ties everything together with bold flavor.

Sweet caramelized onions, juicy steak, and that crispy, golden croissant make this feel like something you’d find at a street food festival—but better, because you made it at home.

Ingredients

For the Filling:

• Steak of your choice (ribeye, sirloin, or shaved beef)
• Salt and black pepper, to taste
• Chopped fresh parsley, for garnish
• 1 onion, sliced into rings
• 1–2 tablespoons oil or butter, for cooking
• Mozzarella cheese, shredded or sliced
• Croissants, halved lengthwise

For the Cowboy Butter:

• ½ cup butter, melted
• 2–3 garlic cloves, minced
• 1 tablespoon fresh parsley, chopped
• 1 teaspoon Dijon mustard
• 1 teaspoon Worcestershire sauce
• ¼ teaspoon paprika
• Salt and black pepper, to taste
• Optional: a pinch of red pepper flakes or lemon juice for brightness

Step-by-Step Instructions

Step 1: Caramelize the Onions

• Slice onions into rings.
• In a skillet or on a grill pan, cook onions over medium-low heat in oil or butter until soft and golden (about 10–15 minutes).
• Set aside.

Step 2: Cook the Steak

• Season steak with salt, pepper, and any additional seasoning you love.
• Grill or sear in a hot skillet until cooked to your preferred doneness.
• Let rest, then slice or dice thinly.
• Garnish with chopped parsley.

Step 3: Make the Cowboy Butter

• In a bowl, mix melted butter, garlic, parsley, Dijon, Worcestershire, paprika, and seasoning.
• Stir well and set aside for drizzling and spreading.

Step 4: Assemble the Croissants

• Slice croissants in half lengthwise and lightly toast cut sides on a skillet or grill.
• Spread cowboy butter on the bottom half.
• Add a layer of mozzarella cheese while warm so it starts to melt.
• Top with steak slices, caramelized onions, more cowboy butter, and a bit more cheese.
• Close with the top croissant half and press gently.

Pro Tips and Serving Suggestions

• Want extra crisp? Toast the whole sandwich panini-style or wrap in foil and bake at 350°F for 5–7 minutes.
• Serve with garlic fries, coleslaw, or a fresh green salad.
• Make extra cowboy butter—it also tastes great on grilled corn, shrimp, or steak.
• These croissants work great for meal prep—just reheat in the oven or air fryer.
