Harissa Seabass and Roasted Vegetables

A couple weeks back I posted a picture of my Harissa Seabass and roasted vegetables on instagram and it proved to be really popular. So popular that 90% of the people who took part on my poll said they wanted a step by step. The tutorial can be found saved over on my Instagram stories.

I thought some people might prefer to have it written down, as I know I personally find it easier to see the steps written down, so here it is.

Harissa is actually one of my favourite spices to cook with. I just love how versatile it is and how it came make the simplest ingredients become something exotic. It goes amazingly with Seabass and that’s the fish I use for this recipe. It is a strong spice with a distinctive flavour, so I’d say go easy on it if you’re not into spice. If you can’t find any in your local shops, you can order it on Amazon for free delivery.

It is a very easy recipe, minimal effort required. In fact all you have to do is chop the vegetables and they don’t even have to be neat. It is the perfect weekday dinner, as you can just shove it in the oven and chill for half hour before adding the fish. Who doesn’t like that? And Seabass cooks so quickly, which is what makes it perfect for this.

If you really wanted to, you could even make the vegetables the night before. Then all you have to do is heat them in the oven and add the fish.

  • 1 Red Onion
  • 1 Red Bell Pepper
  • 2 Spring Onions
  • 1 Courgette
  • 4 Baby Potatoes
  • 1 cup Cherry Tomatoes
  • 2 cloves Garlic
  • 2 Boneless Seabass Filletts
  • 5 tbsp Harissa Paste
  • Salt and Pepper To Taste
  • Olive Oil
  • 1/2 Lemon
  • Coriander To Garnish


  • Start by preheating your oven to 200degrees.
  • Chop all your vegetables except for the spring onion, I like to just rip it with my hands so it’s still long rather than small pieces.
  • Drizzle some olive oil on it and add 2 teaspoons of Harissa, season with salt and pepper and mix well using your hands.
  • Roast for 30 minutes or until our potatoes are cooked.
  • Rub a teaspoon of Harissa on your Seabass until it is coated in it, and place it skin side up on top of your vegetables. Put it back in the oven for 10 minutes or until the fish is cooked all the way through.
  • Spray or drizzle some lemon juice on it, garnish with a lemon slice and some coriander and enjoy hot!


Please adjust cooking times according to your oven and make sure to check throughout so the food does not burn.
If you prefer it to be extra spicy, add more harissa.
