Ingredients
- Four 4-5 oz Pieces of halibut
- Salt to taste
- Oil for searing
- Lime juice to taste
Moroccan Butter
- 1 Tbsp (15ml) Canola oil
- ½ a medium onion, chopped
- 2 Garlic cloves, coarsely chopped
- 1 Tbsp (30 ml) Sweet paprika
- 2 tsp (10ml) cumin seeds or ground cumin
- Pinch of Cayenne
- Salt to taste
- ½ cup (120 ml) White wine
- Juice of ½ a Lime
- 1 lb (454 g) of butter, cubed and cold
Couscous
- 2 cups (500 ml) Couscous
- 2 ½ cups (625 ml) Boiling water
- 2 Tbsp Olives chopped
- ¼ cup (60ml) Dried black currants
- 2 Tbsp (30 ml) Cilantro, chopped
- 3 Tbsp (45 ml) Parsley, chopped
- 2 Tbsp (30g) Butter
- 1/8 tsp Salt
- Lime juice
- Boiling water to cover
Methods
- Preheat the oven to 300°F/150°C
- Pour dry couscous into a baking dish. Evenly distribute olives and currants over top and cover with boiling water. Cover the dish with plastic wrap to trap in the heat. Allow to rest for 10 minutes.
- Prepare your butter poaching liquid. Heat oil in an oven proof pan or pot. Add onions and garlic and sauté until softened. Add sweet paprika, cumin, cayenne, and a dash of salt and cook for 1 minute. Pour in wine and let reduce for 2 minutes. Squeeze in fresh lime juice and add all of the butter. Allow to melt over gentle heat for approximately 3 minutes, or until butter is fully incorporated. Keep the liquid to just below a simmer. It should not boil.
- Season halibut with salt and sear in a hot oiled pan. Cook for 2 minutes or until a crust develops on one side. Flip and transfer fish to the pan of Moroccan butter cooked side up. Spoon the butter over the fish several time to incorporate the flavours. Place the fish in the butter into the oven and cook for 3-6 minutes until fish is cooked.
- Remove plastic wrap from couscous and fluff with a fork. Add cilantro, parsley, butter, salt, and lime juice. Stir to combine.
- Remove the cooked fish from the butter and plate with the warm couscous with a drizzle of the poaching butter overtop and a fresh spritz of lime juice. Note – you can keep the poaching liquid in the fridge to use for another recipe later.
Serving Suggestions
Pair the dish with a crisp green salad or roasted vegetables such as carrots, zucchini, or eggplant to complement the Moroccan flavour profile. For beverages, a dry white wine like Chardonnay or Viognier pairs wonderfully with the buttery richness, while a light red such as Pinot Noir can also work for those who prefer red wine. Non-alcoholic options like sparkling water with citrus or a lightly spiced herbal tea can enhance the aromatic experience.
For entertaining, consider serving the couscous family-style in a large dish with the halibut arranged on top and extra butter sauce on the side. This allows guests to help themselves and creates a warm, inviting dining atmosphere.

This Moroccan butter-poached halibut recipe is a stunning example of how bold spices and simple techniques can transform a dish into something truly memorable.
