Serves 2
Prep Time: 10 minutes |
Cook Time: 12 minutes |
Total Time: 22 minutes
Ingredients
- 1 pound flank steak or skirt steak, trimmed
- 2 crusty rolls or baguette pieces, split
- 1 large yellow onion, thinly sliced
- 2 tablespoons olive oil, divided
- 2 tablespoons butter
- 2 cloves garlic, minced
- 3 tablespoons mayonnaise
- 1 teaspoon Dijon mustard
- 1 cup arugula, packed
- Salt and black pepper to taste
Instructions
- Bring the steak to room temperature and pat dry, then season both sides generously with salt and black pepper.
- Heat 1 tablespoon olive oil and 1 tablespoon butter in a large skillet over medium high heat until shimmering. Add the steak and sear 3 to 4 minutes per side for medium rare, adjust time for thickness, then transfer to a cutting board to rest 5 minutes.
- While the steak rests, add the remaining 1 tablespoon olive oil and 1 tablespoon butter to the same skillet, reduce heat to medium, add the sliced onion and a pinch of salt, cook, stirring occasionally, until golden and softened about 8 minutes.
- Mix the mayonnaise, Dijon, and minced garlic in a small bowl to make the quick aioli, season with a little salt and pepper.
- Thinly slice the steak against the grain into strips. Lightly toast the split rolls under the broiler or in a hot pan.
- Assemble by spreading aioli on each roll half, layer sliced steak on the bottom half, top with caramelized onions and arugula, close the sandwich and press lightly, serve immediately.
Tips & Tricks
- Pat the steak dry before searing to get a good crust and avoid steaming.
- Rest the steak five minutes so juices redistribute and slices stay juicy.
- Use the hot skillet for onions after searing steak to capture browned bits and extra flavor.
- Slice against the grain for tender bites that are easy to chew.
- Toast the roll just enough to add crunch without making it hard to bite through.
Serving Ideas
- Serve with kettle chips and a pickle for a classic deli style meal.
- Cut into smaller pieces and offer as party sliders for casual get togethers.
- Pair with a simple green salad to balance the richness for a weeknight dinner.
- Pack in foil for a hearty lunch on the go.
