Ingredients
- Flank steak (1 lb): Lean and flavorful cut perfect for grilling, offering tender slices when cooked medium-rare.
- Baguette or ciabatta rolls (2): Crusty artisan bread that holds all the fillings without becoming soggy.
- Garlic cloves, minced (2): Adds aromatic, savory depth to the steak marinade for enhanced flavor.
- Mayonnaise (1/4 cup): Creamy base for the Sriracha sauce, creating smooth texture and richness.
- Sriracha sauce (1 tbsp): Spicy chili sauce that delivers a smoky kick to the sandwich spread.
- Romaine or arugula lettuce (1 cup): Fresh, crisp greens that add a peppery crunch and vibrant color.
- Medium tomato, sliced (1): Juicy, ripe slices providing a refreshing contrast to the savory steak.

Instructions
- Marinate the Flank Steak
-
In a bowl, combine the minced garlic, salt, pepper, and olive oil to create a flavorful marinade. Coat the flank steak thoroughly with this mixture and let it rest at room temperature for 30 minutes. This step allows the steak to absorb the seasonings and tenderize before cooking.
- Preheat and Cook the Steak
-
Heat a grill or skillet over medium-high heat until hot. Place the marinated steak on the grill and cook for 5 to 7 minutes per side, depending on your preferred doneness. For medium-rare, aim for 130°F internal temperature. This ensures a juicy, tender steak with a delicious charred exterior.
- Rest and Slice the Steak
-
Once cooked, remove the steak from the heat and let it rest for 5 minutes. Resting allows juices to redistribute through the meat, keeping it moist. Then, slice the steak thinly against the grain to maximize tenderness and ease of eating.
- Prepare the Sriracha Mayo Sauce
-
While the steak rests, combine mayonnaise and Sriracha sauce in a small bowl. Stir well and adjust the amount of Sriracha to taste for your preferred spice level. This creamy, spicy mayo will elevate the sandwich with a vibrant flavor boost.
- Assemble the Sandwich
-
Slice open the baguette or ciabatta rolls and spread a generous layer of the Sriracha mayo inside. Layer on the sliced steak, followed by crisp lettuce and fresh tomato slices. The combination of textures and flavors creates a balanced and satisfying bite.
- Serve Immediately
-
Enjoy your Marry Me Steak Sandwich while the steak is warm and the bread is still crisp. Pair with your favorite side dishes like sweet potato fries or a fresh salad for a complete meal.
- Allowing the steak to marinate and rest properly is key to juicy, flavorful meat.
- Slice steak against the grain to ensure maximum tenderness in each bite.
- Customize the Sriracha mayo heat to suit your preference for spice.
Storage Tips
Store any leftover steak separated from the bread and vegetables to prevent sogginess. Keep steak refrigerated in an airtight container for up to 3 days, and reheat gently before assembling the sandwich again.
