The Impossible™ Slider

$3.49 – 210 Cal

The Impossible™ Slider features a 2-ounce plant-based patty made from a blend of soy protein and heme, which provides a “meaty” flavor and texture without using animal products. It is typically topped with smoked cheddar cheese, crisp pickles, and fire-roasted onions. While the patty itself is larger and “heftier” than the standard 1-ounce beef patty, it is served on the same signature soft square bun.

Cross-Contamination: Prepared on shared kitchen equipment where Beef, Fish, and Egg items are also handled.

How to make The Impossible™ Slider :

  • Prep the Patty: Use store-bought Impossible™ Ground Beef. Press it into a thin 2×2 inch square between sheets of parchment paper.
  • Add Ventilation: Use a small dowel or straw to poke 5 holes in the center of the patty to ensure even cooking and steam distribution.
  • The Onion Bed: Sauté finely minced onions in a small amount of water or vegetable broth on a hot griddle.
  • Steam-Grill: Place the plant-based patty directly on the onions. Do not flip it.
  • The Bun Steam: Place the bottom half of the bun (cut side down) on the patty, then rest the top bun on top of the bottom bun to trap the onion steam.
  • Assembly: After 4–5 minutes, remove from the heat. Add a slice of smoked cheddar and a single dill pickle chip before serving.
