Cooking zucchini and yellow squash on a Blackstone griddle brings out a delicious, slightly caramelized flavor that steamed vegetables can’t match. The griddle works especially well for families because it cooks evenly and quickly.

Before using the griddle, make sure it’s clean and preheated. This method is simple enough to adapt with different seasonings or to pair with a variety of mains.

Choose a cut based on texture and presentation:

  • Cut in Rounds: Slice zucchini into 1/4-inch rounds for quick, even cooking.
  • Diagonal Cut: Cut at an angle for larger slices with more surface area for browning.
  • Planks: Slice lengthwise into thicker planks if you prefer a steak-like piece.
