Roasting Your Veggies

If you struggle to eat enough vegetables in your diet, and are used to boiling and steaming vegetables, roasting them brings out a whole new flavour profile.

Cauliflower is one vegetable that has a very pleasant flavour when roasted. In this dish, we are adding some paprika and garlic powder, and a little lemon post cooking, however there are a whole host of favourings that you can experiment with the create a delicious overall taste.

Roasted Cauliflower Ingredients:

A cauliflower, cut into florets

Olive oil

Paprika

Garlic Powder

Lemon wedges

A few parsley leaves

Salt and black pepper

How to Make this Dish:

The first step is to pre-heat the oven to 220 degrees Celsius (425 Fahrenheit)

Then cut the cauliflower into florets. Smaller florets will cook faster.

Next place the florets into a bowl and top with the olive oil, paprika and garlic powder. Mix with a big spoon so that the florets are evenly coated.

Next place the florets on a baking sheet and spread them out. Place into the oven and cook for around 18-20 minutes.

Serve with a garnish of parsley leaves and a squeeze of lemon juice.

Cooking the Cauliflower in the Air Frier

You can also cook the cauliflower in the air frier instead of the oven. This should be a little quicker at the same temperature. To cook in the air frier, follow the initial steps for coating the florets, then place in the air frier for around 15 minutes, giving the cauliflower a quick shake half way through.
