Ingredients

For the cauliflower steaks:

• 1 head of cauliflower

• Olive oil, for brushing

• 1 tablespoon olive oil (for sauce)

• 1 clove garlic, minced or crushed

• 1 tablespoon agave syrup

• 1 tablespoon Dijon mustard

• ½ teaspoon smoked sea salt

• 1 tablespoon water

• Juice of ½ lemon

For the mushroom filling:

• 250–300 g (8.8–10.6 oz) mushrooms, finely chopped

• 1 tablespoon butter (or olive oil for vegan)

• 1 teaspoon salt

• Black pepper, to taste

• 1 medium onion, finely diced

• 2 tablespoons Greek yogurt or sour cream

For topping:

• 200 g (7 oz) mozzarella cheese, shredded

Step-by-Step Cooking Directions

1. Prepare the cauliflower
   Remove the outer leaves and trim the base of the cauliflower. Slice into thick “steaks” (about 1–1.5 inches thick). You’ll get 2–3 good slices from the center; use the remaining florets for roasting separately.

2. Roast the cauliflower (first stage)
   Preheat your oven to 140°C (284°F). Arrange the steaks on a parchment-lined baking tray and brush both sides lightly with olive oil. Bake for 5 minutes to begin softening.

3. Make the seasoning glaze
   In a small bowl, mix 1 tablespoon olive oil, minced garlic, agave syrup, Dijon mustard, smoked sea salt, water, and lemon juice. Stir until well combined.

4. Glaze the cauliflower
   Brush the glaze generously over the partially roasted cauliflower steaks. Return them to the oven at 120°C (248°F) and cook for another 10 minutes. You can repeat this process for any remaining steaks or florets, using the same glaze and temperature.

5. Prepare the mushroom filling
   In a large skillet, melt butter over medium heat. Add the chopped mushrooms and cook for 5–7 minutes, stirring occasionally, until most of the moisture has evaporated. Season with salt and pepper.

6. Add onion and cook down
   Add the diced onion to the mushrooms and continue frying until the onions are soft and translucent, about 5 more minutes.

7. Finish the mushroom mixture
   Stir in Greek yogurt or sour cream. Mix well and cook for another 2 minutes. The result should be creamy and rich but not runny. Remove from heat.

8. Assemble the dish
   Remove the roasted cauliflower steaks from the oven. Top each with a generous spoonful of mushroom filling. Then sprinkle or layer mozzarella cheese over each portion.

9. Final bake with cheese
   Increase oven temperature to 200°C (400°F). Bake the assembled cauliflower steaks for 5 minutes or until the cheese is fully melted and lightly golden.

10. Serve and enjoy
    Plate your cauliflower steaks and garnish with fresh herbs, extra smoked salt, or cracked black pepper if desired. Serve hot.

Cooking Tips

• Slice cauliflower carefully: Use a sharp knife to get even, intact steaks

• Don’t skip the soak time: Giving cauliflower a bit of time in the oven before adding glaze helps it cook evenly

• Use firm mushrooms: Button or cremini mushrooms hold their shape and flavor best

• Evaporate mushroom juice fully: Prevents sogginess in your final bake

• Use parchment paper: For easy clean-up and nonstick baking

• Grate cheese yourself: Pre-shredded cheese may not melt as smoothly

Variations to Try

• Make it vegan: Use plant-based yogurt and vegan cheese

• Add greens: Stir in spinach or kale to the mushroom filling

• Use blue cheese: Swap mozzarella for gorgonzola or brie for richness

• Make it spicy: Add chili flakes or smoked paprika to the glaze

• Try balsamic reduction: Drizzle after baking for sweetness and tang

• Swap mushrooms: Use oyster or shiitake for deeper umami

Feel free to adapt based on what’s in season or in your fridge.

Frequently Asked Questions (FAQ)

1. Can I make this dish ahead of time?

It’s best enjoyed fresh, but you can freeze portions. Reheat in the oven to retain texture.

3. Can I use other vegetables instead of cauliflower?
Yes. Thick slices of eggplant or large portobello mushrooms work well.
