Step‑by‑Step Instructions for Marry Me Steak Sandwich
Step 1: Preheat the Cooking Surface
Start by preheating a cast iron skillet or grill pan over medium-high heat for about 5 minutes. You want it hot enough that a drop of water sizzles upon contact. This is essential for achieving that perfect sear on your steak, which is the heart of the Marry Me Steak Sandwich.
Step 2: Sear the Steak
Once the skillet is hot, season the 8 oz flank or sirloin steak generously with salt and pepper. Place the steak in the skillet and sear it for 3-4 minutes on each side for a beautiful medium-rare doneness. Look for a crusty, brown exterior, which ensures a flavorful bite for your sandwich.
Step 3: Prepare the Flatbreads
While your steak is cooking to perfection, take this time to prepare the flatbreads. Lightly brush each flatbread with 1 tablespoon of olive oil, making sure to coat them evenly. This will help them crisp up beautifully in the skillet and add a delightful flavor to your Marry Me Steak Sandwich.
Step 4: Rest the Steak
Once the steak is seared, remove it from the skillet and let it rest on a cutting board for about 5 minutes. This rest period is crucial, as it allows the juices to redistribute throughout the meat, making it tender and juicy when you slice it for the sandwich.
Step 5: Grill the Flatbreads
In the same preheated skillet, add the oiled flatbreads, grilling each side for about 2 minutes until they are golden brown and slightly crisp. Keep a close eye on them, as they can go from perfectly golden to burnt quickly. This creates a wonderful texture for your Marry Me Steak Sandwich.
Step 6: Assemble the Sandwich
Now it’s time to build your delicious Marry Me Steak Sandwich! On one flatbread, spread 3 tablespoons of herbed cheese evenly. Layer on the sliced steak, followed by 1 cup of caramelized onions and 1 cup of peppery arugula. This will add layers of flavor and texture to your sandwich.
Step 7: Top and Serve
Carefully place the second flatbread on top of the filled one, pressing gently to adhere the layers together. Slice the sandwich in half to expose all that deliciousness, and serve immediately while warm. This Marry Me Steak Sandwich is best enjoyed fresh for the ultimate taste experience!

Expert Tips for the Best Marry Me Steak Sandwich

Marry Me Steak Sandwich Recipe FAQs
How do I choose the right steak for my sandwich?
Absolutely! Opt for flank steak if you're looking for tenderness or sirloin for a richer flavor. Look for cuts with good marbling, as this will enhance the juiciness during cooking.
How should I store leftovers?
For best results, wrap any leftover assembled Marry Me Steak Sandwich in foil and store it in the refrigerator for up to 3 days. When you're ready to enjoy it again, just reheat it in the oven to maintain that delicious texture.
Can I freeze the sandwich?
I recommend freezing the individual components instead of the assembled sandwich. You can freeze the steak and caramelized onions in airtight bags for up to 2 months. Just ensure they’re completely cooled before placing them in the freezer.
How do I reheat the sandwich to keep it delicious?
To revive your Marry Me Steak Sandwich, preheat your oven to 350°F (175°C). Wrap the sandwich in foil and heat for about 10-15 minutes or until warmed through. This method helps restore the crispiness of the flatbreads while ensuring the steak stays juicy.
Are there any dietary considerations I should keep in mind?
Very! If you're serving this sandwich to someone with dietary restrictions, simply swap out the herbed cheese spread for a dairy-free version. Also, keep an eye on gluten content—make sure to choose gluten-free flatbreads if needed!
What if my steak turns out tough?
The more the merrier, and don’t worry too much! If your steak isn’t as tender as you’d like, it might have been overcooked. Try slicing against the grain for a more tender bite. Ensure your skillet is adequately heated during searing, and always let the steak rest before slicing!
