Ingredients For Steak Croissant Sandwich

Steak Croissant Sandwich

• 2 pound ribeye steak
• 1 large onion, sliced
• 4 slices pepper jack cheese
• 4 buttery croissants
• 3 tablespoons Chipotle Cream Sauce (Herdez)
• 2 tablespoons Worcestershire sauce
• 2 tablespoons butter
• 2 tablespoons avocado oil
• 3 tablespoons steak seasoning

Chimichurri Sauce

• 1 bunch Italian parsley, finely chopped
• 1 bunch cilantro, finely chopped
• 5 cloves garlic, finely minced
• ½ cup olive oil
• ¼ cup red wine vinegar
• Juice from 1 lemon
• 1 teaspoon salt
• 1 teaspoon black pepper
• ½ teaspoon red pepper flakes

What Is a Reverse Sear?

A reverse sear is a cooking method where the steak is slowly cooked at a low temperature before finishing with a high-heat sear. Unlike traditional steak cooking, where the outside is seared first, the reverse sear allows the steak to cook evenly from edge to edge.

First, the steak is smoked at a lower temperature until it is close to your desired internal temperature. Then, it is finished over high heat to create a flavorful crust on the outside.

As a result, this method gives you better control over the doneness while adding incredible smoky flavor. For this recipe, the ribeye is smoked until it reaches 110°F before being seared and finished at 130°F for a perfect medium-rare steak.

Other Cuts of Steak That Will Work

While ribeye is an excellent choice because of its marbling and tenderness, several other cuts work well for this steak sandwich.

• New York Strip: A flavorful option with a slightly firmer texture.
• Sirloin: A leaner cut that still delivers great steak flavor.
• Filet Mignon: Extremely tender and mild in flavor.
• Flank Steak: A budget-friendly option that works well when sliced thin against the grain.
• Skirt Steak: Offers bold beef flavor and is excellent for sandwiches.

No matter which cut you choose, slicing the steak into thin slices against the grain will help create the most tender bite.

How to Make a Steak Croissant Sandwich

1. Smoke the Ribeye Steak

Preheat your smoker to 250°F and set it up for indirect cooking. Add hickory wood chunks for bold smoky flavor.

Lightly coat the ribeye with avocado oil, then generously season all sides with steak seasoning. Insert a meat thermometer to monitor the internal temperature throughout the cook.

Place the steak on the smoker away from direct heat and allow it to cook slowly and evenly.

2. Caramelize the Onions

While the steak cooks, slice the onion into thin strips.

Get the butter melted in a large skillet over medium‑low heat, then add the onions. Cook them for 25 to 30 minutes, stirring every 5 minutes so they soften up and build that deep flavor.

When the onions reach that golden‑brown, caramelized sweet spot, add the Worcestershire sauce and work it through the pan.

Take them off the heat when they reach a deep golden color. That’s when you know you nailed it.

3. Prepare the Chimichurri

Get the parsley, cilantro, and garlic chopped down fine, then bring them together with olive oil, red wine vinegar, lemon juice, salt, black pepper, and red pepper flakes. Give it a thorough mix and set it aside to come alive.

4. Reverse Sear the Steak

As soon as the steak reaches 110°F, get it out of the smoker and fire things up to high for the sear.

Sear the steak over high heat until it reaches your preferred doneness. For medium‑rare, pull the steak at 130°F and let it rest for 15 minutes so the juices settle back in.

5. Assemble the Sandwich

While the steak rests, slice the croissants in half with a serrated knife. Toast the inside of each croissant until golden brown.

After resting, place the steak on a cutting board and slice it into thin pieces against the grain.

Build each sandwich with sliced steak, caramelized onions, pepper jack cheese, chimichurri, and chipotle cream sauce.

Place the top of the croissant over the sandwich, serve immediately and Enjoy!

Expert Tips On Steak Croissant Sandwich

• Let the steak rest before slicing to keep the juices inside.
• Always slice steak against the grain for a tender bite.
• Use a serrated knife when cutting croissants to avoid crushing them.
• Don’t rush caramelized onions; low and slow creates the best flavor.
• Add the cheese while the steak is warm so it melts slightly.
• Use a meat thermometer for the most accurate steak temperature.

Variations On Steak Croissant Sandwich

• Swap pepper jack cheese for provolone or Swiss cheese.
• Add roasted peppers for extra flavor.
• Use smoked brisket instead of steak.
• Add sautéed mushrooms for a hearty sandwich.
• Replace chipotle cream sauce with horseradish sauce for a different flavor.

Storage

Store leftover steak, onions, and chimichurri separately in airtight containers in the refrigerator for up to 3 days.

For the best results, reheat the steak gently before assembling a fresh sandwich. Avoid storing assembled croissant sandwiches because the bread can become soggy.

Frequently Asked Questions About Steak Croissant Sandwich

Can I make this steak sandwich without a smoker? Yes. You can cook the steak in the oven, grill, or cast iron skillet before finishing with a high-heat sear.

What temperature should steak be for a sandwich? Medium-rare at 130°F is recommended because the steak stays tender and juicy after slicing.
