Ingredients

Scale

Cauliflower Steaks

  • 1 large head cauliflower
  • Neutral oil, for grill
  • 2 scallions, thinly sliced
  • 2 tbsp. toasted sesame seeds

Teriyaki Marinade and Sauce

  • 1/2 cup reduced-sodium soy sauce
  • 3 cloves garlic, grated
  • 2 tbsp. unseasoned rice wine vinegar
  • 2 tsp. grated peeled ginger
  • 1 tsp. toasted sesame oil
  • 1/4 cup plus 1 tbsp. cold water, divided
  • 2 tbsp. cornstarch
  • 1/3 cup light brown sugar
  • 1/4 tsp. kosher salt

Instructions

  1. Prepare Cauliflower Steaks: Arrange the cauliflower head stem down on a cutting board. Trim the stem if necessary so the cauliflower sits flat. Use a sharp knife to cut cauliflower into 1/4-inch thick slices. You will get 3 or 4 center ‘steaks’ that hold together; set these aside and reserve any crumbly ends for another use. Place the steaks in a single layer in a 13″ x 9″ baking dish.
  2. Marinate Cauliflower: In a medium bowl, mix soy sauce, grated garlic, rice wine vinegar, grated ginger, toasted sesame oil, and 1/4 cup cold water. Pour this marinade over the cauliflower steaks and turn them to coat. Let them sit, flipping halfway through, for 30 minutes to absorb the flavors.
  3. Prepare Cornstarch Mixture: While the cauliflower marinates, whisk together cornstarch and 1 tablespoon cold water in a small pot until smooth. Add light brown sugar and whisk until combined. Set aside.
  4. Season Cauliflower: Carefully transfer the marinated cauliflower steaks to a metal baking sheet and season evenly with kosher salt.
  5. Make Teriyaki Sauce: Pour the marinade from the baking dish into the pot with the cornstarch and brown sugar mixture. Heat over medium-high heat, bringing to a boil. Stir occasionally and cook for 4 to 6 minutes until the sauce thickens enough to coat the back of a spoon. Remove from heat to prevent burning.
  6. Preheat Grill: Prepare a grill or heat a grill pan over medium heat. Preheat for about 5 minutes. Clean the grates and brush lightly with neutral oil to prevent sticking.
  7. Grill Cauliflower Steaks: Place the cauliflower steaks evenly spaced on the grill. Grill undisturbed for 6 to 8 minutes until deep grill marks develop on the bottom. Using a large metal spatula, carefully flip each steak and continue grilling for another 6 to 8 minutes until marked on the other side and fork-tender.
  8. Serve: Transfer the grilled cauliflower to a serving platter. Generously brush with the warm teriyaki sauce. Garnish with thinly sliced scallions and toasted sesame seeds for added flavor and texture. Serve immediately.

Notes

  • Use a very sharp knife when slicing cauliflower to keep steaks intact.
  • Do not flip the steaks too soon while grilling to allow nice grill marks to form.
  • Reserve crumbly cauliflower ends for soups, salads, or roasting.
  • Adjust the sweetness in the teriyaki sauce by adding more or less brown sugar as desired.
  • For a gluten-free version, substitute soy sauce with tamari.
