Ingredients :
For the Steak
- 1 pound ribeye steak
- Steak seasoning (to taste)
- Olive oil
For the Creamy Mushroom Sauce
- 8 ounces mushrooms, sliced
- ½ large onion, thinly sliced
- 2 tablespoons butter
- 1 tablespoon all-purpose flour
- 2 cups heavy cream
- 1 cup beef broth
- 2 tablespoons Worcestershire-style sauce
- 1 tablespoon fresh rosemary, chopped
- 1 tablespoon fresh thyme leaves
- ½ cup grated Parmesan cheese
- Salt and black pepper, to taste
For the Frites
- 2 russet potatoes, very thinly sliced
- Oil for frying
- Cajun seasoning or preferred spice blend
For Assembly
- Ciabatta rolls or sturdy sandwich bread, split and toasted
- Fresh chives, thinly sliced
Instructions :
1. Season and Prepare the Steak
Pat the ribeye steak dry using paper towels. Generously season both sides with steak seasoning. Let the steak rest at room temperature for about 30 minutes so it cooks evenly. Lightly brush with olive oil before cooking.
2. Cook the Steak
Heat a grill or heavy skillet over high heat. Once hot, place the steak on the cooking surface and sear for about 3–4 minutes per side for medium-rare, adjusting the time based on your preferred doneness.
Remove the steak from heat and allow it to rest for at least 10–15 minutes. This step is important, as it helps the juices redistribute and keeps the meat tender. Once rested, slice the steak thinly against the grain.
3. Make the Creamy Mushroom Sauce
In a large skillet over medium heat, melt the butter. Add the sliced mushrooms and onions, cooking until softened and lightly caramelized, about 7–8 minutes.
Sprinkle the flour over the mixture and stir continuously for 2–3 minutes to cook out the raw flour taste. Add the rosemary and thyme, then slowly pour in the beef broth while stirring. Follow with the heavy cream and Worcestershire-style sauce.
Let the sauce simmer gently until it thickens into a rich, creamy consistency. Stir in the Parmesan cheese until fully melted and smooth. Season with salt and black pepper to taste. Reduce heat and keep warm.
4. Prepare the Crispy Frites
Slice the potatoes very thin using a mandoline or sharp knife. Place the slices in cold water and soak for 30 minutes to remove excess starch.
Drain and thoroughly dry the potato slices. Heat oil in a deep pot or fryer to 350°F (175°C). Fry the potatoes in small batches until golden brown and crispy. Remove and drain on paper towels, then toss with Cajun seasoning while still warm.
5. Assemble the Sandwich
Toast the ciabatta rolls until lightly crisp. On the bottom half of each roll, layer sliced steak generously. Spoon the creamy mushroom sauce over the steak, then top with a handful of crispy frites. Sprinkle with fresh chives and close the sandwich with the top half of the roll.
Serve immediately while warm.
Tips for Best Results
