Leftover steak deserves more than just being reheated the next day. This sandwich gives it a full upgrade with layers of bold flavors and fresh ingredients.
A crispy toasted baguette becomes the perfect base for savory olive tapenade, tender steak slices, caramelized onions, juicy tomatoes, and fresh arugula. It’s simple but tastes incredibly elevated.
This is the kind of no-fuss meal that proves leftovers can become something even better the second time around.

The Ultimate Leftover Steak Sandwich
Ingredients
Method
- Slice the baguette in half and lightly toast until golden brown and crispy.
- Spread a generous layer of olive tapenade on both sides of the toasted baguette.
- Add sliced leftover steak evenly over the sandwich.
- Layer with sweet caramelized onions.
- Add fresh tomato slices.
- Top with a handful of peppery arugula.
- Finish with a drizzle of extra virgin olive oil.
- Close the sandwich, slice in half, and prepare for the best bite of your weekend.
Notes
- This recipe works best with leftover grilled steak, but any tender sliced steak will work.
- For extra flavor, warm the steak slightly before assembling the sandwich.
- Serve right away to keep the baguette crispy.
