Full Recipe

Ingredients

• 1 large head of cauliflower

• 250 g (about 2 ½ cups) mushrooms, finely chopped

• 2 tbsp olive oil (plus more for brushing)

• 1 medium onion, finely diced

• 2 cloves garlic, minced

• 1 tsp fresh thyme leaves (or ½ tsp dried thyme)

• Salt and black pepper, to taste

• ½ cup grated Parmesan cheese

• 2 tbsp breadcrumbs (optional, for extra texture)

• Fresh parsley, chopped (for garnish)

Cooking Directions

1. Prepare the cauliflower: Trim the leaves and base of the cauliflower, leaving the core intact. Slice the cauliflower into 2–3 cm thick steaks. Depending on the size, you’ll get about 3–4 steaks. Save the smaller florets that fall off for another use.

2. Roast the cauliflower: Preheat the oven to 200°C (400°F). Place the steaks on a parchment-lined baking sheet, brush with olive oil, and season with salt and pepper. Roast for 20 minutes until golden and tender.

3. Make the mushroom filling: While the cauliflower roasts, heat 2 tbsp olive oil in a skillet over medium heat. Add onion and garlic, sauté until soft. Stir in the chopped mushrooms and thyme, cooking until the mushrooms release moisture and become golden. Season with salt and pepper.

4. Fill and bake: Remove cauliflower steaks from the oven. Top each steak generously with the mushroom-thyme mixture. Sprinkle Parmesan (and breadcrumbs if using) over the top. Return to the oven for another 10 minutes until the cheese is melted and bubbly.

5. Serve: Garnish with fresh parsley and an extra sprinkle of Parmesan before serving warm.

The Origins and Inspiration Behind the Dish

Cauliflower steaks became popular as part of the plant-based eating trend, offering a satisfying alternative to meat while keeping flavors bold and exciting.

Ingredient Spotlight

• Cauliflower: Mild yet nutty when roasted, it’s a low-carb alternative to grains and meat.

Storage and Reheating Tips

Store leftovers in an airtight container in the fridge for up to 3 days. Reheat in the oven at 180°C (350°F) for 10 minutes to keep the cauliflower from turning soggy. Avoid microwaving as it may soften the texture too much.

Common Variations to Try

• Spice it up with a pinch of chili flakes.

• Make it vegan by replacing Parmesan with nutritional yeast or a dairy-free cheese alternative.
