The image shows a close-up of a grilled sandwich cut into three stacked pieces on a wooden board, placed on a white marbled surface. Each sandwich piece has two thick slices of golden-brown toasted bread with a crispy, slightly crunchy texture. Inside, the bottom layer contains melted white cheese that looks stretchy and creamy, followed by a layer of cooked meat with a brownish color, topped with fresh green spinach leaves. The sandwich layers are uneven, showing the gooey cheese melting and the greens peeking out between the bread slices. The whole scene looks warm and inviting with the rustic placement of the sandwiches and a few scattered green leaves to the side. photo taken with an iphone --ar 4:5 --v 7

Ingredients

16 ounce Boneless Ribeye Steak
8 slices White Cheese
8 slices Sourdough Bread
2 cups Arugula
1 tablespoon Avocado Oil
4 tablespoons Unsalted Butter
½ teaspoon Salt

Instructions

Step 1: Take the unsalted butter out of the refrigerator 1 to 2 hours before making the sandwich to allow it to soften.
Step 2: Preheat your oven to 425°F (220°C).
Step 3: Remove the ribeye steak from the refrigerator and cut it while still cold. Trim off any large fat areas and discard them.
Step 4: Lay the steak slices horizontally and slice as thin and short as possible. Sprinkle with ½ teaspoon of salt.
Step 5: Heat a cast-iron or sauté pan over high heat with 1 tablespoon of avocado oil. When hot, add the steak slices spread out in a single layer and sear each side for 2 minutes until browned.
Step 6: Continue searing in batches until all steak is cooked. Let the steak rest on a cutting board or plate.
Step 7: Spread softened butter on one side of all sourdough bread slices (all 8 slices).
Step 8: Place 4 slices of bread butter-side down on an aluminum-lined baking tray.
Step 9: Top each bread slice with one slice of white cheese.
Step 10: Layer thin-sliced steak evenly over the cheese, about 5 to 6 slices per bread piece.
Step 11: Distribute ½ cup arugula over the steak on each sandwich, then top with another slice of white cheese.
Step 12: Finish by placing the remaining 4 bread slices on top, butter-side facing up.
Step 13: Bake the sandwiches in the oven for 15 minutes.
Step 14: Broil on high for 2 minutes, carefully watching to prevent burning the top bread slice.
Step 15: Remove from the oven immediately and cut the sandwiches in half or serve whole. Enjoy warm!

Tips & Variations

For extra flavor, add a spread of horseradish sauce or garlic aioli under the steak layers.
Substitute white cheese with provolone or mozzarella for a different melt and taste.
If you don’t have avocado oil, olive oil works well for searing the steak.
Use a cast-iron skillet for the best sear on the steak slices.

Storage

Store leftover sandwiches wrapped tightly in the refrigerator for up to 2 days. To reheat, place in a preheated oven at 350°F (175°C) for 10 minutes or until warmed through. Avoid microwaving to keep the bread from becoming soggy.

How to Serve

A stack of three grilled cheese sandwich halves rests on a wooden board over a white marbled background. Each sandwich half is made with thick slices of golden brown toasted bread that have a crunchy texture. Inside, layers include melted white cheese oozing slightly, fresh green leafy spinach, and slices of cooked meat with a slightly pink center. The sandwich layers are packed and show some melted cheese stretching between the slices. A bit of green spinach peeks out from the edges in each sandwich. Photo taken with an iphone --ar 4:5 --v 7

FAQs

Can I use a different cut of steak?

Yes, while ribeye is ideal for its tenderness and flavor, other cuts like sirloin or strip steak can work if sliced thinly and cooked quickly.

Is it necessary to broil the sandwiches?

Broiling helps achieve a crisp, golden top on the bread and melts the cheese perfectly. If you prefer, you can bake longer at a lower temperature, but broiling gives the best finish.
