How to Make Marinated Flank Steak Sandwich
Follow these simple steps to prepare this delicious Marinated Flank Steak Sandwich:
Step 1: Prepare the Marinade
In a small bowl, whisk together the canola oil, lemon juice, soy sauce, Worcestershire sauce, Dijon mustard, dark brown sugar, black pepper, salt, and minced garlic. This vibrant marinade is your secret weapon for a mouthwatering steak.
Step 2: Marinate the Steak
Place the flank steak in a large resealable bag and pour the marinade over it. Seal the bag, squeezing out as much air as possible, then refrigerate. Allow the steak to marinate for at least 4 hours, or up to 8 for optimal flavor infusion.
Step 3: Make Garlic-Herb Butter
In a small bowl, whisk together the softened butter, minced garlic, chives, thyme, parsley, and salt until well combined. This garlic-herb butter will elevate your sandwich to new heights.
Step 4: Preheat the Grill
Ignite all burners on your grill, close the lid, and preheat for about 5 minutes. Clean the grilling grate thoroughly and oil it to prevent sticking.
Step 5: Grill the Onions and Steak
Brush the onion slices with oil and place them directly on the grill alongside the marinade-soaked flank steak. Cook the onions until soft and charred, roughly 5 minutes per side. For the steak, grill until it reaches a deep brown color and an internal temperature of 125°F; expect about 3 to 5 minutes per side for a perfect medium-rare.
Step 6: Assemble the Sandwiches
Once grilled, transfer the steak and onions to a cutting board to rest for 5 minutes. Slice the steak against the grain on a bias and separate the onion rings. Generously butter the cut side of each ciabatta piece with your garlic-herb butter, then place them cut side down on the grill for 1 to 2 minutes until toasted.
Step 7: Add Toppings
Place the grilled bread on a platter, add layers of sliced steak, charred onions, and slices of provolone cheese. Turn off one burner and position the topped bread on that side of the grill. Cover and let it sit until the cheese is melted, approximately 1 minute.
Step 8: Serve
Transfer the sandwiches back to the platter, top each with a handful of arugula, and the other half of the ciabatta. Serve these beauties immediately, and watch them disappear in seconds.
These Marinated Flank Steak Sandwiches with Charred Onions are more than just food; they’re a fantastic experience that will have you dreaming of backyard get-togethers long after the last bite. Whether you’re a seasoned grill master or a newbie in the kitchen, this recipe ensures a delicious adventure awaits. Enjoy every savory moment!

FAQs About Marinated Flank Steak Sandwich
What is Marinated Flank Steak Sandwich?
A Marinated Flank Steak Sandwich is a delicious creation that features tender flank steak marinated in a flavorful blend of ingredients. The marinade typically includes oil, lemon juice, soy sauce, and various spices, giving the meat a deliciously rich flavor. Once marinated, the steak is grilled to juicy perfection and served on crusty ciabatta bread, often with charred onions and cheese. This sandwich is perfect for summer barbecues or casual family dinners.
How long should I marinate the flank steak?
For the best flavor, flank steak should be marinated for at least 4 hours. However, if you can let it soak overnight, you’ll enhance the flavors even more. Marinating for a longer period allows the acids in the marinade to penetrate deeply, tenderizing the meat while imparting a depth of flavor that’s hard to resist. Just remember that marinating for too long can lead to mushy steak, so aim for a sweet spot between 4 to 8 hours.
Can I use other cuts of meat for a flank steak sandwich?
Absolutely! While flank steak is ideal for its flavor and tenderness, other cuts like skirt steak, sirloin, or even chicken breast can work nicely as substitutes. Each cut brings its own unique taste and texture, so feel free to get creative. Just be mindful that different meats might require slight adjustments in cooking time or marinating conditions to achieve the same tender, juicy sandwich.
What can I serve with a Marinated Flank Steak Sandwich?
A Marinated Flank Steak Sandwich pairs wonderfully with a variety of sides. Consider serving it with a fresh arugula salad, sweet potato fries, or grilled vegetables for a well-rounded meal. For a more indulgent treat, homemade potato chips or a zesty coleslaw can also complement the flavors, providing a crunchy contrast to the tender steak. Don’t forget about adding your favorite dipping sauces to elevate the sandwich experience!
