Lemon, Ginger & Rosemary Halibut with Roasted Sweet Veg Medley

Freezer Food Challenge Series

There’s something deeply satisfying about creating a nourishing, vibrant meal entirely from what you already have on hand.

This Freezer Food Challenge recipe is especially meaningful — featuring some of the beautiful halibut fillets caught by Craig on his Norway trip last year, carefully frozen and saved for the perfect moment.

Paired with homegrown frozen squash, sweet potatoes, sweetcorn, and a handful of fresh green vegetables from the fridge, this dish is a celebration of clean eating, zero waste, and thoughtful cooking. Bright lemon, warming ginger, and fragrant rosemary bring everything together into a meal that feels both comforting and elevated.

Ingredients (Serves 2–3)

For the halibut:

• 2–3 halibut fillets (frozen, then thawed)

• 1 lemon (zest + juice)

• 1 thumb-sized piece fresh ginger, grated or ground ginger from the cupboard (I always have ginger in the freezer)

• 1–2 sprigs rosemary, finely chopped

• 1 tbsp olive oil

• Sea salt & black pepper

For the roasted veg:

• 1–2 cups frozen squash (homegrown if you have it — even better)

• 1–2 sweet potatoes, chopped into chunks

• 1 cup sweetcorn (frozen)

• 1–2 cups mixed green vegetables (broccoli, green beans, or whatever’s in the fridge)

• 1 tbsp olive oil

• Salt, pepper, and optional pinch of chilli flakes

Method

Prep the Veg

Preheat your oven to 200°C (180°C fan).

Spread the squash and sweet potato chunks on a large baking tray. Drizzle with olive oil, season well, and toss to coat. Roast for 20 minutes.

After 20 minutes, add the sweetcorn and green vegetables, give everything a quick stir, and return to the oven for another 10–15 minutes until tender and lightly caramelised.

Marinate the Halibut

While the veg roasts, pat the thawed halibut dry.

In a small bowl, mix:

• Lemon zest and juice

• Grated ginger

• Chopped rosemary

• Olive oil

• Salt and pepper

Rub this mixture gently over the fillets and let sit for 10–15 minutes.

Cook the Fish

Heat a non-stick pan over medium heat.

Cook the halibut fillets for about 3–4 minutes per side (depending on thickness), until opaque and flaky. Spoon any leftover marinade over the fish as it cooks for extra flavour.

Bring It All Together

Plate the roasted vegetables and top with the halibut fillets. Spoon over any pan juices and finish with an extra squeeze of lemon if you like that fresh brightness.

Tips & Variations

Add a handful of fresh herbs (parsley or dill) at the end for extra freshness

Swap rosemary for thyme if that’s what you have

Toss the roasted veg with a handful of spinach right before serving for extra greens

If your halibut is especially thick, finish it in the oven for a couple of minutes

Final Thoughts

This dish is exactly what the Freezer Food Challenge is all about — using what you already have to create something nourishing, beautiful, and full of meaning. There’s something special about that halibut, knowing where it came from, and pairing it with homegrown produce makes it even more rewarding.

Simple food. Thoughtful choices. Big flavour.

Until next time — keep it clean, keep it creative, and keep dreaming.
