Cauliflower Steaks with Roasted Red Pepper Sauce & Chimichurri Recipe
Introduction
Cauliflower steaks with roasted red pepper sauce and chimichurri make a vibrant, flavorful dish that’s perfect for a wholesome vegetarian meal. The combination of smoky spices, creamy sauce, and fresh herb chimichurri creates a satisfying plate that even meat lovers will enjoy.

Ingredients
- 1 large head cauliflower (cut into 2.5cm thick “steaks”)
- 3-5 tbsp olive oil
- Salt & pepper (to taste)
- 1 tsp smoked paprika
- 1/2 tsp ground cumin
- 1/2 tsp turmeric (optional, for color & earthiness)
- 3 red bell peppers
- 1-2 handfuls walnuts
- Juice of 1 lemon
- Salt & pepper (to taste)
- Water (as needed)
- 1 cup fresh parsley (finely chopped)
- 2 tbsp fresh oregano (or 1 tsp dried)
- 1 fresh chili (finely chopped, or 1/2 tsp chili flakes)
- 2-3 tbsp red wine vinegar (or lemon juice)
- 1/2 cup olive oil
- Salt & pepper (to taste)
Instructions
- Step 1: Preheat your oven or air fryer to 200°C (400°F).
- Step 2: Prepare the cauliflower by mixing olive oil with smoked paprika, ground cumin, turmeric (if using), salt, and pepper. Brush this mixture onto both sides of the cauliflower steaks.
- Step 3: Roast the cauliflower and bell peppers. For the oven, place the cauliflower steaks and whole red bell peppers on parchment-lined trays and roast for 25–30 minutes, flipping the cauliflower once, until the steaks are golden and the peppers are blistered. If using an air fryer, arrange the cauliflower steaks and peppers in the basket (if they fit) and cook for 20–25 minutes at 200°C, flipping the steaks halfway through.
- Step 4: Once cooled, peel the skins off the roasted peppers and discard the skins.
- Step 5: Make the roasted red pepper sauce by blending the peeled peppers with walnuts, lemon juice, salt, and pepper. Gradually add water to reach a smooth, creamy consistency. Adjust seasoning to taste.
- Step 6: Prepare the chimichurri by mixing chopped parsley, oregano, chili, red wine vinegar, olive oil, salt, and pepper in a bowl. Let it sit for 5–10 minutes to develop flavor.
- Step 7: To serve, spread the roasted red pepper sauce on a plate. Place the cauliflower steaks on top, drizzle generously with chimichurri, and garnish with extra parsley.
Tips & Variations
- For added richness, include a tablespoon of vegan parmesan in the red pepper sauce.
- Use mild chili flakes or omit chili if you prefer a milder chimichurri.
- Try substituting walnuts with almonds or pine nuts for a different nutty flavor in the sauce.
- If cauliflower steaks are fragile, handle gently when flipping to keep them intact.
Storage
Store leftover cauliflower steaks and sauces in airtight containers in the refrigerator for up to 3 days. Reheat the cauliflower gently in the oven or air fryer to retain texture, and stir the chimichurri before serving. The roasted red pepper sauce may thicken in the fridge—add a splash of water or olive oil when reheating or serving.

FAQs
Can I grill the cauliflower steaks instead of roasting?
Yes, grilling works well and imparts a smoky flavor. Brush the seasoned steaks with oil and grill over medium heat for about 5-7 minutes per side until tender and charred.
Can I prepare the sauces in advance?
Absolutely. Both the roasted red pepper sauce and chimichurri can be made a day ahead. Store in covered containers in the fridge and bring to room temperature before serving for the best flavor.

Ingredients
Cauliflower Steaks
- 1 large head cauliflower, cut into 2.5cm thick ‘steaks’
- 3–5 tbsp olive oil
- Salt and pepper, to taste
- 1 tsp smoked paprika
- 1/2 tsp ground cumin
- 1/2 tsp turmeric (optional, for color and earthiness)
Roasted Red Pepper Sauce
- 3 red bell peppers
- 1–2 handfuls walnuts
- Juice of 1 lemon
- Salt and pepper, to taste
- Water, as needed to achieve smoothness
Chimichurri
- 1 cup fresh parsley, finely chopped
- 2 tbsp fresh oregano (or 1 tsp dried)
- 1 fresh chili, finely chopped (or 1/2 tsp chili flakes)
- 2–3 tbsp red wine vinegar (or lemon juice)
- 1/2 cup olive oil
- Salt and pepper, to taste
Instructions
- Preheat Oven or Air Fryer: Set your oven or air fryer to 200°C (400°F) to prepare for roasting the cauliflower and peppers.
- Season the Cauliflower: In a bowl, combine olive oil, smoked paprika, ground cumin, turmeric (if using), salt, and pepper. Brush this seasoning mixture generously onto both sides of the cauliflower steaks to ensure full flavor penetration.
- Cook the Cauliflower and Peppers: If using an oven, place the cauliflower steaks and whole red bell peppers on parchment-lined trays. Roast for 25 to 30 minutes, flipping the cauliflower steaks halfway through, until golden brown and tender, and the peppers are blistered. If using an air fryer, arrange the cauliflower steaks and red peppers in the basket (space permitting) and cook for 20 to 25 minutes at 200°C, flipping the steaks once midway. The cauliflower should be tender and golden, and the peppers soft with charred skin.
- Peel the Peppers: Once cooled enough to handle, peel the skins off the roasted red peppers and discard the skins for a smoother sauce texture.
- Prepare Roasted Red Pepper Sauce: In a blender or food processor, combine the peeled roasted peppers, walnuts, lemon juice, salt, and pepper. Blend while gradually adding water until the sauce reaches a creamy and smooth consistency. Taste and adjust seasoning as necessary.
- Make the Chimichurri: In a bowl, mix finely chopped parsley, oregano, chili, red wine vinegar (or lemon juice), olive oil, salt, and pepper. Let the chimichurri sit for 5 to 10 minutes to allow the flavors to meld and develop.
- Assemble the Dish: Spread the roasted red pepper sauce on a serving plate. Place the roasted cauliflower steaks on top of the sauce. Drizzle liberally with chimichurri and garnish with extra fresh parsley for a vibrant presentation.
Notes
- Turmeric is optional but adds a beautiful golden hue and subtle earthiness to the cauliflower.
- If you don’t have vegan parmesan for the sauce, you can substitute with nutritional yeast or omit entirely.
- The sauce consistency can be adjusted by adding more or less water depending on your preference.
- The chimichurri can be made ahead and refrigerated for up to 24 hours to deepen the flavors.
- For a spicier chimichurri, increase the amount of fresh chili or chili flakes.
- This dish is naturally vegan and gluten-free.
