A steak sandwich, with its blend of tenderness, juiciness, cheesiness, and a satisfying crunch, is worth cooking a steak for. Utilizing leftover cooked steak elevates its appeal, especially after a holiday feast or a big BBQ.

This guide is not a rigid recipe but an inspiration to transform the humble sandwich into a flavor-packed experience, reminding us of its extraordinary potential. So, whether you’re using freshly cooked steak or leftovers, let’s dive into the art of crafting a delicious steak sandwich.

steak sandwich ingredients

The Main Ingredients

  • Steak – A quality steak is going to make a big difference. Opt for tender options like strip steak, sirloin, picanha, tri-tip, or flank steak. While ribeye is flavorful, be mindful of potential fat and gristle.
  • Bread – A crusty roll or ciabatta provides an excellent base for a hearty steak sandwich. Consider a long French baguette for a steak sandwich gathering, slicing smaller pieces for sharing.
  • Cheese – Something nice and melty is best. I love brie or provolone or explore alternatives such as gruyere, gouda, bleu, or your personal favorite.
  • Onions – Onions are essential for a steak sandwich, in whichever form you prefer. Sweet onions, lightly caramelized still keeping their shape. Or experiment with using raw or quick pickled red onions, fried shallots or even beer-battered onion rings.
  • Lettuce – Arugula (aka rocket) adds a delightful peppery note and contrasts beautifully with the robust flavors of the steak and melty cheese. Or try butter lettuce for sweeter more delicate notes.

Sauce Inspiration

The addition of a sauce can elevate the sandwich experience, transporting you to different flavor realms. Whether using leftovers or crafting a quick sauce with minimal ingredients, taking a few extra minutes to enhance this sandwich is well worth it.

  • Steak/Burger sauce – just combine equal parts mayo, mustard and ketchup for a seriously easy and delicious sauce that goes great with this sandwich.
  • Chimichurri – This game-changing herby and zesty condiment adds a freshness to the sandwich that once you try it, is hard to resist using on just about everything.
  • Horseradish mayo – Combine some prepared horseradish with mayo and you have this creamy sandwich sauce with a peppery kick.
  • Garlic mayo – Make it from scratch or simply combine some chopped fresh garlic with mayonnaise.
  • BBQ sauce – You probably have some in the fridge, and it goes great with steak, onions and cheese.
  • Fig jam – Adds a nice earthy sweetness.

More Condiments & Topping Inspo

More options to go on your sandwich.

  • Pickles – Not essential, but bread & butter pickles served on the side go super well and are a great crunchy contrast.
  • Onion rings – Thick cut or onion strings, both are fun and tasty on top or on the side.
  • Fried shallots – The deep flavor of shallots makes everything more sophisticated.
  • Tomatoes – Tomatoes add so much when they are in season. If out of season, I’ll leave them off.
  • MushroomsRoast ’em or sautee in the same skillet while you caramelize the onions.

Going Beyond Bread

While the focus here is on the sandwich, there are exciting ways to vary it using the same ingredients. Try an open-face sandwich with only using bread on the bottom. Or transform it into a salad by tearing up the bread (even toasting it to make crunchy croutons). Do what feels right for you—it’s going to be delicious.

What to Serve with the Sandwiches

  • Fries – Yep, steak frites is great with sandwiches too.
  • Chips – Kettle chips are great, or slice some potatoes yourself and easily make chips in the air fryer.
  • Veggies
  • Salads – An arugula salad with a bright and fresh lemon vinaigrette is a steakhouse dream.
  • Onion Rings – Beer battered crunchy delight.
  • Potato Salad
