Introduction
Grilled cauliflower steaks offer a flavorful and satisfying vegetarian main dish. Paired with a vibrant romesco sauce, this recipe brings smoky, tangy, and nutty flavors together for a delightful meal.

Ingredients
- 1 large head of cauliflower (sliced lengthwise through the core into 4 “steaks”)
- 2 tablespoons fresh lemon juice
- 1 tablespoon olive oil
- Sea salt
- 1/4 cup slivered almonds
- 1/2 large tomato (chopped)
- 1/2 cup thinly sliced roasted red peppers (packed)
- 1/2 tablespoon fresh lemon juice
- 1 teaspoon garlic (minced)
- 1/4 teaspoon sea salt
- 1/4 teaspoon ground cumin
- Sliced parsley (for garnish)
Instructions
- Step 1: Preheat your oven to 350°F. Spread the slivered almonds on a small baking sheet and bake for 3-5 minutes until lightly golden. Watch carefully to prevent burning, then set aside. Preheat your grill to medium heat.
- Step 2: Place the cauliflower steaks on a cutting board. In a small bowl, mix 2 tablespoons lemon juice with 1 tablespoon olive oil. Brush half of this mixture over the tops of the cauliflower steaks and sprinkle with sea salt.
- Step 3: Place the cauliflower steaks oil-side down on the grill. Cook for 8-9 minutes until charred and starting to soften. Brush the remaining oil mixture on the top, flip the steaks, and grill for another 8-9 minutes until fork tender.
- Step 4: While cauliflower cooks, place the chopped tomato in a food processor and blend until smooth.
- Step 5: Add the roasted red peppers, toasted almonds, 1/2 tablespoon lemon juice, minced garlic, 1/4 teaspoon sea salt, and ground cumin to the food processor. Blend until smooth and creamy to make the romesco sauce.
- Step 6: Serve the grilled cauliflower steaks topped with romesco sauce and garnish with sliced parsley.
Tips & Variations
- For extra smoky flavor, use smoked paprika in the romesco sauce or grill the cauliflower over charcoal.
- If you don’t have a grill, roast the cauliflower steaks at 425°F for 20-25 minutes until tender and charred around the edges.
- Swap almonds with walnuts or hazelnuts for a different nutty taste in the sauce.

Ingredients
Cauliflower Steaks
- 1 large head of cauliflower (sliced lengthwise through the core into 4 “steaks”)
- 2 tablespoons fresh lemon juice
- 1 tablespoon olive oil
- Sea salt, to taste
Romesco Sauce
- 1/4 cup slivered almonds
- 1/2 large tomato (chopped)
- 1/2 cup thinly sliced roasted red peppers (packed)
- 1/2 tablespoon fresh lemon juice
- 1 teaspoon garlic (minced)
- 1/4 teaspoon sea salt
- 1/4 teaspoon ground cumin
- Sliced parsley (for garnish)
Instructions
- Toast almonds: Preheat your oven to 350°F. Spread the slivered almonds onto a small baking sheet and bake for about 3-5 minutes until they turn lightly golden brown. Watch closely to prevent burning. Remove and set aside.
- Preheat the grill: While the almonds toast, preheat your grill to medium heat to prepare for grilling the cauliflower steaks.
- Season cauliflower steaks: Place the cauliflower steaks on a cutting board. In a small bowl, mix 2 tablespoons fresh lemon juice with 1 tablespoon olive oil. Brush half of this mixture evenly over the top of the cauliflower steaks. Sprinkle sea salt over them to taste.
- Grill cauliflower (first side): Place the cauliflower steaks on the grill, oil-coated side down. Grill for about 8-9 minutes until they develop char marks and start to soften.
- Season and flip: Brush the remaining lemon juice and oil mixture over the top of the steaks. Carefully flip each steak and grill the other side for another 8-9 minutes until the cauliflower is fork-tender.
- Puree tomato: Meanwhile, place the chopped half tomato in a food processor and process until smooth and broken down.
- Blend Romesco sauce: Add the toasted almonds, roasted red peppers, minced garlic, 1/2 tablespoon fresh lemon juice, sea salt, and ground cumin to the food processor with the tomato. Process all ingredients together until the sauce is creamy and smooth.
- Serve: Spoon the Romesco sauce over the grilled cauliflower steaks and garnish with sliced parsley. Serve immediately for the best flavor and texture.
Notes
- Ensure almond toasting is closely monitored as they can burn quickly.
- Use a grill with a lid if possible to maintain consistent heat for even cooking.
- If you do not have a grill, you can grill the steaks in a grill pan over medium-high heat on a stovetop.
- To make the recipe vegan and vegetarian, verify that the roasted red peppers and other ingredients do not include any animal products.
- Leftover Romesco sauce can be stored in the refrigerator for up to 3 days and used as a dip or spread.
