What You Need to Make This Recipe

Crafting this incredible Marry Me Steak Sandwich truly starts with a few star players: tender flank steak for that satisfying bite, sweet yellow onions for depth, and, of course, the rich heavy cream and Parmesan for that irresistible sauce.

How to Make Marry Me Steak Sandwich

Creating this indulgent Marry Me Steak Sandwich involves a few simple, sequential steps that build incredible flavor. First, you’ll lovingly caramelize the onions to golden perfection, then sear the seasoned flank steak until tender. Next, whip up the dreamy garlic Parmesan sauce, a step as satisfying as making a homemade sun-dried tomato pesto grilled cheese. Finally, assemble everything onto crusty rolls with melted provolone for a truly comforting meal.

Pro Tips for Making This Marry Me Steak Sandwich

Achieving perfection with this Marry Me Steak Sandwich is all about attention to detail, and I’ve learned a few tricks over the years that I’m excited to share. For the flank steak, always slice it against the grain after resting to ensure maximum tenderness; this makes all the difference in every bite. When it comes to the sauce, don’t be afraid to let it simmer gently to thicken, allowing all those beautiful garlic and Parmesan flavors to truly meld.

My Secret Trick: For the most luscious caramelized onions, I always add a tiny splash of water or broth to the pan if they start to stick and brown too quickly. This deglazes the pan, builds flavor, and helps them cook down slowly and evenly without burning, creating that deep, sweet foundation for the Marry Me Steak Sandwich.

What to Serve With Marry Me Steak Sandwich

When I’m making a hearty Marry Me Steak Sandwich, I love to pair it with sides that complement its richness without overpowering it. Here are a few of my go-to suggestions:

• Crispy Garlic Parmesan Fries: A classic pairing that echoes the flavors of the sauce.
• Simple Green Salad with Vinaigrette: A fresh, tangy salad cuts through the richness beautifully, offering a refreshing contrast.
• Roasted Asparagus or Broccoli: These add a touch of green and a lovely earthy flavor.

My practical tip is to always keep it simple with your sides. The Marry Me Steak Sandwich is the star, so let it shine!

How to Store Marry Me Steak Sandwich

To enjoy your Marry Me Steak Sandwich leftovers, I recommend storing the components separately if possible. Keep the cooked steak, caramelized onions, and creamy sauce in airtight containers in the refrigerator for up to 3 days. This way, the bread won’t get soggy. My personal tip is to reheat the steak and sauce gently on the stovetop or in the microwave, then quickly toast a fresh sub roll before assembling.

Nutritional Benefits

This Marry Me Steak Sandwich is more than just delicious; it’s packed with goodness! Flank steak provides a fantastic source of high-quality protein, essential for energy and muscle health, while the fresh spinach in the sauce adds vital vitamins.

Ingredients

  

For the Steak

• 1 lb Flank Steak or Sirloin Steak, about 1-inch thick
• 1 tbsp Olive Oil
• 1 tsp Garlic Powder
• 1/2 tsp Onion Powder
• 1/2 tsp Smoked Paprika
• 1/2 tsp Salt
• 1/4 tsp Black Pepper

For the Caramelized Onions

• 2 medium Yellow Onions thinly sliced
• 1 tbsp Butter
• 1 pinch Salt

For the Marry Me Cream Sauce

• 2 tbsp Butter
• 4 cloves Garlic minced
• 1/4 cup Sun-Dried Tomatoes packed in oil, drained and chopped
• 1 tsp All-Purpose Flour optional, for thickening
• 1 1/2 cup Heavy Cream
• 1/2 cup Parmesan Cheese grated
• 1/4 cup Chicken Broth or vegetable broth
• 1 cup Fresh Spinach loosely packed
• 1/4 tsp Red Pepper Flakes optional
• 1/2 tsp Salt to taste
• 1/4 tsp Black Pepper to taste

For Assembly

• 2 Crusty Sub Rolls or Baguette Sections about 8-10 inches each, split lengthwise
• 4-6 slices Provolone Cheese or Mozzarella
• 1 tbsp Fresh Parsley chopped, for garnish (optional)

Equipment

• Large Skillet (or cast iron pan)
• Saucepan
• Baking Sheet
• Sharp knife
• Cutting board

Method

 

Prepare the Caramelized Onions

• Melt 1 tablespoon of butter in a large skillet over medium-low heat. Add the thinly sliced yellow onions and a pinch of salt. Cook slowly, stirring occasionally, for 20-30 minutes until deeply golden brown and very soft. Remove from skillet and set aside.

Cook the Steak

• While onions are cooking, pat the flank steak dry with paper towels. In a small bowl, combine garlic powder, onion powder, smoked paprika, salt, and black pepper. Season the steak generously on both sides with the spice mixture.
• Heat 1 tablespoon of olive oil in the same large skillet (or a separate one if needed) over medium-high heat until shimmering. Sear the steak for 3-5 minutes per side for medium-rare, or longer for desired doneness. A 1-inch thick steak will usually take around 4 minutes per side. Remove steak from skillet, transfer to a cutting board, and tent with foil. Let rest for at least 5-10 minutes before slicing.

Make the Marry Me Cream Sauce

• In a medium saucepan, melt 2 tablespoons of butter over medium heat. Add minced garlic and chopped sun-dried tomatoes; sauté for 1-2 minutes until fragrant.
• If using, sprinkle in the 1 tsp of flour and cook for 1 minute, stirring constantly, to create a roux. Gradually whisk in the heavy cream and chicken broth, bringing the mixture to a gentle simmer. Cook for 2-3 minutes, stirring, until the sauce slightly thickens.
• Stir in the grated Parmesan cheese, fresh spinach, and red pepper flakes (if using). Cook until the cheese is melted and the spinach has wilted, about 1-2 minutes. Season with salt and black pepper to taste. Remove from heat.

Assemble the Sandwiches

• Preheat your broiler to high. Slice the rested flank steak thinly against the grain. Set aside.
• Place the split sub rolls face up on a baking sheet. Lightly toast under the broiler for 1-2 minutes until golden. Watch carefully to prevent burning.
• Spoon a generous layer of caramelized onions onto the bottom half of each toasted roll. Top with the thinly sliced steak. Drizzle generously with the Marry Me Cream Sauce, ensuring the steak is well coated.
• Place 2-3 slices of provolone cheese over the steak and sauce on each sandwich. Return the baking sheet to the broiler for 1-3 minutes, or until the cheese is melted and bubbly and slightly golden. Again, watch closely.
• Carefully remove from the oven, garnish with fresh chopped parsley if desired, and serve immediately. Prepare for compliments!

Notes

For best results, slice the steak against the grain to ensure maximum tenderness. The caramelized onions can be made ahead of time and stored in the fridge for up to 3 days. Adjust the amount of red pepper flakes to your preferred spice level. If the sauce becomes too thick, add a splash of chicken broth or water to reach your desired consistency.

Conclusion

This Marry Me Steak Sandwich truly brings together the best of comforting flavors and satisfying textures, making it a wonderful addition to any meal plan. It’s a testament to how simple ingredients, with a little love and creativity, can transform into an extraordinary meal that’s both hearty and approachable for any busy family.
