Smash Burger Sub With Pesto and Peaches

Recipe by Dee

Ingredients

  • 4 oz. ground beef

  • 1/4 of a large sweet onion

  • 1 peach or nectarine, thinly sliced

  • 1 small cucumber, sliced on a bias

  • 2-3 tbsp. pesto

  • 1 hoagie roll, sliced in half

  • Fine sea salt

  • Unsalted butter

Directions

  • Heat a 10 inch cast iron griddle over medium heat for 5 minutes.
  • While the griddle is heating, divide the ground beef into 2 equal pieces and roll them into balls. Place one ball between two pieces of parchment paper and use a tortilla press or a flat bottomed pan to flatten the ground beef to a circle that is 1/8 of an inch thick.
  • Remove the top sheet of parchment paper and flip the second piece with the burger on it onto the pan, burger side down. Carefully peel off the second piece of parchment paper and cook the burger for about 1 minute on one side (it will shrink), then flip and cook for 30 to 60 seconds more. Remove from the pan and repeat with the second piece.
  • Add a pat of butter to the griddle and once it has melted, add the sliced sweet onion. Cook, stirring constantly, until the edges of the onion turn translucent, 3 to 4 minutes. Remove from the pan.
  • Add a bit more butter to the pan and add the halves of the hoagie roll to the pan, cut side down. Toast the bread for 2 to 3 minutes or until golden brown. Remove from the heat.
  • Assemble The Sandwich
  • Spread a thin layer of pesto on both slices of the bread. Then, to the bottom half of the bread, add the burgers, cucumber, peach or nectarine, and sweet onion. Top with the top half of the bread. For ease of eating, consider wrapping the sandwich in parchment paper before cutting in half. Enjoy!

Notes:

  • Nectarines are peaches without the fuzz, so you can use whichever you prefer. I used nectarines but didn’t put it in the title because it didn’t sound right.
  • Use your favorite pesto whether it is store bought or homemade. If you go the homemade route, consider trying this Spinach Pesto.
  •  The burger will shrink rapidly once you add it to the pan and how much it shrinks will depend on how lean the meat is. The ground beef I used was 90% lean and 10% fat. A ground beef mix that is 85% lean and 15% fat may shrink more but may also be more flavorful.

Ramblings: A Very Short Ramble

Yep, I know.

Technically there is more to this smash burger with pesto and peaches than pesto and peaches. There are onions and cucumber as well.

But smash burger with pesto, peaches, cucumber, and sweet onion is a very long title to type and say and it isn’t as alliterative, so shorter title it is!
