Halibut Stuffed With Kale and Feta Pesto

This elegant halibut stuffed with kale and feta pesto offers a sophisticated way to enjoy white fish while keeping your meal nutritious and light. The meaty texture of the halibut provides a sturdy base for the vibrant, savoury filling, which combines the earthy notes of kale with the salty tang of feta cheese. By stuffing the pesto directly into the fillets, the fish stays beautifully moist and takes on all the aromatic flavours of the spring onions and celery during the short roasting process.

As a diabetes-friendly main course, this dish is naturally low in carbohydrates and high in lean protein. It is an ideal choice for a quick midweek supper or a healthy weekend dinner when you want something that feels special but requires minimal effort. Serve these fillets alongside some steamed seasonal greens or a crisp side salad for a well-balanced, heart-healthy meal that doesn't compromise on flavour.

Ingredients for Halibut Stuffed With Kale and Feta Pesto

  • 1 teaspoon grapeseed oil

  • 6 skinless halibut fillets, about 170g (185 g) each

  • Kosher salt and freshly ground black pepper

  • 2 spring onions, white and pale green parts, each cut crosswise into 4 equal pieces

  • 2 cups (130g / 140 g) coarsely chopped stemmed kale

  • 1 rib celery, coarsely chopped

  • 30g (35g / 40 g) crumbled feta cheese

  • 1–2 tablespoons extra-virgin olive oil

How to make Halibut Stuffed With Kale and Feta Pesto

Preheat the oven to 450ºF. Using the grapeseed oil, lightly grease a rectangular baking dish large enough to accommodate the fillets in a single layer.

Place the halibut fillets in the prepared baking dish and season lightly with salt and pepper. Use a sharp knife to slash several deep cuts in the top of each fillet, being careful not to cut all the way through the fish.

In a mini food processor, combine the spring onions, kale, celery, and cheese and process until the ingredients are crumb-sized. Add 1 tablespoon of the olive oil and pulse until a paste forms, adding more oil as needed to achieve a good consistency. Season with salt and pepper.

Use a small spoon or your finger to stuff the pesto into the slits in each fillet, filling them with as much pesto as will fit and allowing it to overflow. Roast until the fish is opaque at the centre when tested with the tip of a knife, about 15 minutes. Let cool for 3 minutes before serving.
