Ingredients

Scale

Cauliflower Steaks

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

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, trimming the stem if necessary for stability. Slice the cauliflower into approximately 1/4 inch thick steaks, reserving the end pieces for another use. Place the steaks in a single layer in a 13″ x 9″ baking dish.
  2. Marinate Cauliflower: In a medium bowl, whisk together 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, turning them to coat evenly. Let them sit, turning halfway through, for 30 minutes to absorb the flavors.
  3. Prepare Thickening Mixture: While the cauliflower marinates, whisk cornstarch with 1 tablespoon cold water in a small pot until dissolved. Stir in the brown sugar until combined.
  4. Season Cauliflower: Carefully transfer the cauliflower steaks onto a metal baking sheet and sprinkle with kosher salt for seasoning.
  5. Make Teriyaki Sauce: Pour the reserved marinade into the pot with the brown sugar and cornstarch mixture. Bring to a boil over medium-high heat, stirring occasionally, and cook until the sauce thickens enough to coat the back of a spoon, approximately 4 to 6 minutes. Remove from heat.
  6. Prepare Grill: Preheat a grill or grill pan to medium heat for about 5 minutes. Clean and oil the grill grates with neutral oil to prevent sticking.
  7. Grill Cauliflower Steaks: Place the cauliflower steaks evenly on the grill. Cook undisturbed until deeply marked on the bottom, about 6 to 8 minutes. Flip them carefully with a large metal spatula and grill for another 6 to 8 minutes until tender and grill-marked on both sides.
  8. Serve: Arrange the grilled cauliflower steaks on a serving platter. Generously slather with the thickened teriyaki sauce. Garnish with thinly sliced scallions and toasted sesame seeds before serving.

Notes

  • Choose a firm, large cauliflower head for the best steaks that hold together on the grill.
  • If your cauliflower steaks break apart, use the smaller pieces in stir-fries or roasted vegetable dishes.
  • Use a grill pan if you don’t have access to an outdoor grill for similar results.
  • The teriyaki sauce can be made ahead and stored in the refrigerator for up to 3 days.
  • This dish is vegetarian and can be served as a main course or a side.
  • Adjust the amount of brown sugar to your preferred sweetness level.
