From Start to Finish: Grilled Cauliflower Steak With Romesco Sauce

Step 1: Prepare the Cauliflower Steaks
Start by removing the leaves from the cauliflower head and cutting it into four thick slices. Aim for about 1 to 1.5 inches thick to ensure they hold together on the grill.
Step 2: Marinate the Steaks
In a small bowl, whisk together 2 tablespoons of fresh lemon juice, 1 tablespoon of olive oil, and a pinch of sea salt. Brush this mixture over both sides of each cauliflower steak, allowing them to marinate for about 10-15 minutes.
Step 3: Grill the Cauliflower
Preheat your grill or grill pan over medium-high heat. Once hot, place the marinated cauliflower steaks on the grill. Grill for about 5-7 minutes on each side, or until they have nice grill marks and are tender. Remove from the grill and set aside.
Step 4: Make the Romesco Sauce
While the cauliflower is grilling, prepare the Romesco sauce. In a blender or food processor, combine the slivered almonds, chopped tomato, roasted red peppers, 1/2 tablespoon lemon juice, minced garlic, 1/4 teaspoon sea salt, and ground cumin. Blend until smooth, adjusting the consistency with a little water if necessary.
Step 5: Serve
Place the grilled cauliflower steaks on a serving platter. Generously spoon the Romesco sauce over each steak. Garnish with sliced parsley for a fresh touch.
Healthier Substitutions

- Use sunflower seeds instead of slivered almonds for a nut-free option.
- Replace olive oil with avocado oil for a higher smoke point.
- Opt for fresh herbs like basil or cilantro for a different flavor profile.
- Swap roasted red peppers with fresh bell peppers for a lighter sauce.
Avoid These Mistakes
- Cutting the cauliflower steaks too thin can lead to them falling apart on the grill.
- Not preheating the grill properly may result in uneven cooking.
- Overcooking the cauliflower can make it mushy; aim for a tender yet firm texture.
- Forgetting to season adequately can make the dish bland; don’t skip the salt and lemon juice!
Prep Ahead & Store
You can prepare the cauliflower steaks and the Romesco sauce in advance. Marinate the cauliflower and store it in the refrigerator for up to 24 hours before grilling. The Romesco sauce can also be made ahead of time and stored in an airtight container for up to a week in the fridge. Just give it a good stir before serving.
Quick Questions

Other great options include tahini sauce, pesto, or even a simple yogurt-based sauce for a creamy contrast.
