The Ultimate Caramelized Onion Steak Sandwich Recipe

A steak sandwich is already a treat, but when you add sweet, rich caramelized onions, it becomes a gourmet delight. This recipe will guide you through creating a delicious caramelized onion steak sandwich that will elevate your lunch or dinner.

Ingredients:

For the Caramelized Onions:

• 2 large onions, thinly sliced
• 2 tablespoons butter
• 1 tablespoon olive oil
• 1 tablespoon brown sugar (optional)
• 1/2 teaspoon salt
• 1/4 teaspoon black pepper
• 1 tablespoon balsamic vinegar

For the Steak:

• 1 pound flank steak or ribeye, trimmed
• 1 tablespoon olive oil
• Salt and pepper to taste
• 1 teaspoon garlic powder
• 1 teaspoon paprika

For the Sandwich:

• 4 crusty rolls or baguettes, halved
• 4 slices provolone or Swiss cheese
• 1 cup arugula or baby spinach
• 1/4 cup mayonnaise (optional)
• 1 tablespoon Dijon mustard (optional)

Instructions:

1. Caramelize the Onions:

1. Heat the butter and olive oil in a large skillet over medium heat.
2. Add the sliced onions and stir to coat them in the oil and butter mixture.
3. Cook the onions, stirring occasionally, for about 20-30 minutes, or until they are golden brown and caramelized. If desired, add brown sugar halfway through the cooking process to enhance the sweetness.
4. Season with salt and pepper, and stir in the balsamic vinegar.
5. Once caramelized, set the onions aside.

2. Prepare the Steak:

1. Preheat your grill or a grill pan to high heat.
2. Rub the steak with olive oil and season generously with salt, pepper, garlic powder, and paprika.
3. Grill the steak for about 4-5 minutes per side for medium-rare, or until it reaches your desired level of doneness.
4. Remove the steak from the grill and let it rest for 5-10 minutes before slicing thinly against the grain.

3. Assemble the Sandwich:

1. Preheat the oven to 350°F (175°C) or use a broiler.
2. Slice the rolls or baguettes in half and, if desired, toast them in the oven for a few minutes until lightly crispy.
3. Spread mayonnaise and Dijon mustard on the bottom halves of the rolls.
4. Layer the sliced steak on the bottom halves of the rolls, followed by a generous portion of caramelized onions.
5. Place a slice of provolone or Swiss cheese over the onions.
6. Top with arugula or baby spinach.
7. Place the top halves of the rolls on the sandwiches.

4. Melt the Cheese (Optional):

1. If you prefer melted cheese, place the assembled sandwiches on a baking sheet and heat them in the oven for 5 minutes or until the cheese is melted and bubbly.

5. Serve:

1. Remove the sandwiches from the oven and let them cool slightly before serving.
2. Cut each sandwich in half, if desired, and serve with your favorite side, such as fries or a salad.

Tips for Perfect Caramelized Onion Steak Sandwiches:

• Onion Choice: Yellow onions are best for caramelizing due to their natural sweetness.
• Steak Resting: Letting the steak rest after grilling helps retain its juices.
• Bread Choice: A crusty roll or baguette provides a good balance of crunch and softness.

Enjoy your gourmet caramelized onion steak sandwich! This combination of tender steak, sweet onions, and melted cheese is sure to satisfy any craving.
