A note about serious food allergies

Sliders are super, and burgers are the bomb, but a classic steak sandwich with cheese and sweet caramelized onion really levels the "meat sandwich" game up a few notches. And this gooey, juicy superstar is served on a pretzel stick, a long pretzel bun bringing all that salty softness to the game. Add a little truffle oil aioli, and you've got a sandwich all-star on your hands. (Or in your hands, as the case may be.)

Cooking Guidelines

To ensure food safety, the FDA recommends the following as minimum internal cooking temperatures:

  • Steak and Pork 145° F (rest cooked meat, 3 minutes) |
  • Seafood 145° F |
  • Chicken 165° F |
  • Ground Beef 160° F |
  • Ground Turkey 165° F |
  • Ground Pork 160° F

Customize It Instructions

  • If using flank steak, follow same instructions as steak strips.

  • If using Impossible burger, follow same instructions as steak strips in Step 4, breaking up burger until heated through, 4-6 minutes.

  • If using chicken breasts, pat dry and, on a separate cutting board, cut into 1” dice. Follow same instructions as steak strips in Step 4, stirring occasionally until chicken reaches minimum internal temperature, 5-7 minutes.

  1. 1

    Roast the Potatoes

    Halve potatoes lengthwise. Add potatoes to prepared baking sheet and toss with 2 tsp. olive oil, half the garlic salt (reserve remaining for steak strips), and a pinch of salt and pepper. Spread into a single layer and roast in hot oven until golden brown and fork-tender, 25-30 minutes, flipping once halfway through. Top roasted potatoes with Parmesan. While potatoes roast, prepare ingredients.

  2. 2

    Prepare Ingredients and Make Truffle Aioli

    Halve and peel onion. Slice halves into thin strips. Combine mayonnaise and truffle oil in a mixing bowl. Set aside. Separate steak strips into a single layer and pat dry.

  3. 3

    Caramelize the Onion

    Place a large non-stick pan over medium heat. Add 2 tsp. olive oil and onion to hot pan and stir occasionally until lightly browned, 4-6 minutes. Add 2 Tbsp. water to pan and bring to a simmer. Once simmering, cook until tender, 8-10 minutes. If pan becomes dry, add water, 1 Tbsp. at a time, until onion is tender. Remove from burner. Stir in sugar until combined. Transfer onion to a plate. Wipe pan clean and reserve. While onion caramelizes, cook steak strips.

  4. 4

    Cook the Steak Strips

    Place another large non-stick pan over medium-high heat and add 1 tsp. olive oil. Add steak strips and remaining garlic salt to hot pan. Stir occasionally until no pink remains and steak strips reach a minimum internal temperature of 145 degrees, 4-6 minutes. Remove from burner. Top with mozzarella. Cover and set aside to melt, 3 minutes.

  5. 5

    Toast Buns and Finish Dish

    Return pan used to cook onions to medium heat. Add pretzel sticks, cut side down, to hot, dry pan. Toast until lightly browned, 2-3 minutes. Remove from burner. Plate dish as pictured on front of card, topping bottom pretzel stick with truffle aioli, steak mixture, onions, and top pretzel stick. Bon appétit!
