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
- 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.
- 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.
- 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.
- Season Cauliflower: Carefully transfer the marinated cauliflower steaks to a metal baking sheet and season evenly with kosher salt.
- 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.
- 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.
- 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.
- 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.
