Choosing the Best Steak for Sandwiches

The key to an exceptional steak sandwich is selecting the right cut. Look for:

• Ribeye (1 to 1½ pounds / 450–680 g) – Rich marbling and bold flavor

• Sirloin (1 to 1½ pounds / 450–680 g) – Leaner but still tender

• Flank steak (1 to 1½ pounds / 450–680 g) – Best when sliced thinly against the grain

Ribeye offers the most tenderness and flavor due to its marbling, while sirloin provides a slightly leaner option that still works beautifully in sandwiches.

Step-by-Step Instructions

Step 1: Bring Steak to Room Temperature

Remove the steak from the refrigerator 30–40 minutes before cooking. This ensures even cooking.

Pat the steak dry with paper towels. Rub with 1 tablespoon (15 ml) olive oil and season evenly with 1 teaspoon (5 g) kosher salt, ½ teaspoon (2 g) black pepper, and ½ teaspoon (1 g) garlic powder.

---

Step 2: Cook the Steak

Heat a cast-iron skillet over medium-high heat until very hot. Place the steak in the pan and cook:

• 4–5 minutes per side for medium-rare

• 5–6 minutes per side for medium

Cooking times will vary depending on thickness.

Transfer the steak to a cutting board and let it rest for 10 minutes before slicing. Resting allows the juices to redistribute.

---

Step 3: Caramelize the Onions

While the steak rests, melt 1 tablespoon (14 g) butter in a skillet over medium heat. Add the sliced onion and ½ teaspoon (2 g) salt.

Cook for 15–20 minutes, stirring occasionally, until the onions become golden brown and soft. Lower the heat if they brown too quickly.

Caramelized onions add sweetness and depth that perfectly complement the savory steak.

---

Step 4: Toast the Rolls

Preheat your oven to 375°F (190°C). Slice the rolls and brush the cut sides with olive oil or melted butter.

Toast for 5–7 minutes until lightly crisp and golden. This step prevents the bread from becoming soggy and adds texture.

---

Step 5: Slice the Steak

Using a sharp knife, slice the steak thinly against the grain. Cutting against the grain shortens muscle fibers, ensuring tender bites.

---

Step 6: Assemble the Sandwiches

Spread mayonnaise or aioli on the bottom half of each roll if desired. Layer sliced steak generously, followed by caramelized onions.

Add a slice of cheese if using and place under the broiler for 1–2 minutes until melted.

Top with fresh arugula or spinach for brightness. Close the sandwich and serve immediately.

Flavor Variations

Garlic Herb Butter Steak

Add 1 tablespoon (14 g) butter mixed with minced garlic and chopped parsley on top of the hot steak before resting.

Mushroom and Swiss

Sauté 1 cup (70 g) sliced mushrooms in olive oil and top the sandwich with Swiss cheese.

Spicy Kick

Add sliced jalapeños or a spicy mustard spread.

Creamy Horseradish Sauce

Mix ¼ cup (60 g) sour cream with 1 tablespoon (15 g) prepared horseradish and ½ teaspoon lemon juice for a bold spread.

Storage and Reheating

Refrigeration

Store leftover sliced steak in an airtight container for up to 3 days.

Reheating

Reheat gently in a skillet over medium-low heat to prevent overcooking. Avoid microwaving too long, as it can toughen the meat.

For best results, assemble sandwiches fresh rather than storing them fully assembled.

Frequently Asked Questions

1. What is the best doneness for steak sandwiches?

Medium-rare to medium is ideal for steak sandwiches. Cooking to medium-rare (internal temperature around 130–135°F / 54–57°C) keeps the meat tender and juicy. Since the steak may be briefly reheated during assembly or broiling, slightly undercooking ensures it doesn’t become dry.

2. How do I keep my steak sandwich from becoming soggy?

Toasting the bread is essential. Brushing the cut sides with olive oil or butter and lightly crisping them in the oven creates a barrier against juices. Also, avoid overloading the sandwich with sauce, and let the steak rest before slicing to reduce excess liquid.

3. Can I grill the steak instead of cooking it in a skillet?

Absolutely. Preheat your grill to high heat and cook the steak for 4–6 minutes per side, depending on thickness and desired doneness. Let it rest before slicing. Grilling adds a smoky flavor that works beautifully in sandwiches.

4. Can I prepare this recipe ahead of time?

You can cook the steak and caramelize the onions ahead of time, storing them separately in the refrigerator. Reheat gently before assembling the sandwiches. However, it’s best to toast the bread and assemble the sandwich just before serving for optimal texture and freshness.
