Transforming Leftover Beef Tenderloin

If you have leftover beef tenderloin or steak, it’s time to get creative in the kitchen. Forget about adding it to a salad – why not make delicious steak sandwiches instead? With a few simple ingredients and some easy steps, you can create mouthwatering hoagie sandwiches with a touch of Philly cheesesteak goodness.

The Ingredients You’ll Need

To make these leftover beef tenderloin or steak sandwiches, gather the following ingredients:

  • Pre-cooked leftover tenderloin or steak
  • Aromatics like onion and garlic
  • Bell peppers, both green and red
  • Pantry essentials such as vegetable oil, Worcestershire sauce, salt, black pepper, and crushed red pepper (optional)
  • Sub or hoagie buns
  • Provolone cheese

How to Make the Sandwiches

  1. Begin by trimming the leftover tenderloin or steak into thin slices, about ¼ inch thick, cutting across the grain.
  2. Slice the onion and bell peppers as well.
  3. In a medium bowl, coat the trimmed meat with Worcestershire sauce, minced garlic, salt, pepper, and crushed red pepper (if desired).
  4. Heat a griddle or large stovetop pan with some vegetable oil. Add the trimmed onion and bell peppers, cooking for about 5 minutes, stirring every 2 minutes.
  5. After 5 minutes, add the meat to the pan and continue cooking for an additional 5 minutes.
  6. Toast the sub buns and layer the cooked meat and vegetables on them.
  7. Complete the sandwich by adding a slice of provolone cheese.

Tips for Success

Keep these tips in mind as you prepare your leftover beef tenderloin or steak sandwiches:

  • Aim for about ¼ pound of meat per sandwich.
  • Cut the beef across the grain, ensuring each slice is about ¼ inch thick. Trim the meat as you cut it.
  • Use two peppers and one medium onion for every 1 to 1 ½ pounds of meat. Adjust the quantities if needed.
  • Cook the vegetables until they are tender but still slightly crunchy.
  • Coat the meat with seasonings and add it to the vegetables halfway through their cooking time.
  • If your pan isn’t large enough to accommodate all the ingredients, cook the vegetables first, transfer them to a covered plate, and then cook the meat. Combine everything before serving.
  • For a Philly cheesesteak twist, melt some provolone cheese onto the hot meat and vegetable mixture before assembling the sandwiches.
