Crispy Onion Smash Burger Stromboli


  • Author: David Andersson
  • Total Time: 45 minutes
  • Yield: 6 slices 1x

Description

At its heart, this particular cooking concept is a creative, modern twist on a classic Italian-American turnover. A traditional version is typically stuffed with cured meats, mozzarella, and marinara sauce. However, an authentic Crispy Onion Smash Burger Stromboli recipe completely reimagines the filling by swapping out the deli meats for seasoned ground beef that has been cooked at a very high heat to develop maximum flavor.
