Ingredients
For the Roasted Cauliflower:
- Cauliflower: 1 whole head
- Olive oil: ~1/4 cup (60 ml)
- Salt: 1 teaspoon
- Black pepper: A pinch
- Paprika: 1 teaspoon
- Garlic powder: 1 teaspoon
- Parmesan cheese: ~3 tablespoons grated (20 g)
For the Filling:
- Onion: 1 medium, finely diced
- Carrot: 1 medium, grated
- Olive oil: 3 tablespoons
- Salt: 1/2 teaspoon
- Black pepper: A pinch
- Garlic powder: 1 teaspoon
- Dried parsley: 1 teaspoon
- Canned tuna: 1 can (80 g), drained (optional)
- Mozzarella cheese: 100 g, shredded
- Chopped parsley: For garnish (optional)
Instructions
- Preheat Your Oven:
- Preheat the oven to 200°C (400°F).
- Clean and Season the Cauliflower:
- Remove the green leaves and trim the stem of the cauliflower so it can sit flat.
- Place the cauliflower in a large pot and blanch it in boiling water for 5-7 minutes. This will help soften it slightly and reduce cooking time. After blanching, drain and pat dry.
- Coat with Seasoning:
- In a small bowl, mix together olive oil, salt, black pepper, paprika, and garlic powder.
- Rub this mixture all over the cauliflower, ensuring it’s evenly coated. This will give it a flavorful crust once roasted.
- Sprinkle Parmesan Cheese:
- Place the cauliflower on a baking sheet lined with parchment paper.
- Sprinkle the top with grated Parmesan cheese.
- Roast the Cauliflower:
- Roast in the preheated oven for 30-35 minutes, or until the cauliflower is tender and golden brown on the outside.
Step 2: Prepare the Filling
- Sauté the Vegetables:
- While the cauliflower is roasting, heat 3 tablespoons of olive oil in a pan over medium heat. Add the diced onion and sauté until soft and translucent.
- Add the grated carrot and continue cooking for another 3-4 minutes.
- Season the Filling:
- Season the mixture with salt, black pepper, garlic powder, and dried parsley. Stir well to combine.
- If using tuna, add it to the pan and break it up with a spoon. Cook until everything is well combined and heated through. Remove from heat.
Step 3: Assemble and Bake
- Fill the Roasted Cauliflower:
- Carefully remove the roasted cauliflower from the oven. Using a small knife, gently create small cavities in the cauliflower florets, making room to spoon in the filling.
- Spoon the vegetable and tuna mixture into the gaps, trying to stuff it as much as possible.
- Add Mozzarella Cheese:
- Sprinkle the shredded mozzarella over the filled cauliflower, allowing it to melt and bind the filling together.
- Return the cauliflower to the oven and bake for another 10-15 minutes, or until the cheese is melted and bubbly.
- Garnish:
- Once baked, remove from the oven and let it cool slightly. Garnish with chopped parsley for a fresh, vibrant touch.
Step 4: Serve and Enjoy
- Slice the cauliflower into wedges and serve hot. Enjoy the combination of roasted, cheesy goodness with the savory filling inside.
