Boil water in a large pot and cook pasta according to package instructions — 10 minutes

Bring to boil a large pot of water. Add pasta and cook per packet MINUS 1 minute. (Note 5).

Just before draining, scoop out 1 cup of pasta cooking water and set aside. Drain pasta.

While pasta cooks, heat olive oil in a skillet over medium heat — 1 minute

Meanwhile, melt 1 tbsp of butter in a large non stick skillet over medium high heat. Add prawns and cook for 1 1/2 minutes on each side until just cooked through. Remove prawns.

Add minced garlic to the skillet and sauté until fragrant — 1 minute

Add halibut fillet to the skillet, season with salt and pepper, and cook until golden brown — 4 minutes per side

In the same skillet, add 1 tbsp butter. Once melted, add garlic. Stir for 20 seconds until fragrant.

Add wine and stir. Simmer for 2 minutes until wine mostly reduces (see video).

Remove halibut from skillet and set aside — 1 minute

Add cream, broth and parmesan. Stir until the parmesan is melted, then leave to simmer for 1 1/2 minutes until it thickens slightly (will thicken more in next step).

In the same skillet, add cherry tomatoes and cook until softened — 3 minutes

Add prawns, stir, then add pasta plus about 1/4 cup of reserved pasta water. Toss pasta (still on stove) and the sauce will thicken in about 30 - 45 seconds and start clinging to the pasta.

Pour in white wine and let simmer until reduced by half — 2 minutes

Take it off the stove before the sauce is as thick as you want - it will thicken more.

Flake the cooked halibut into bite-sized pieces and return to the skillet — 1 minute

Sprinkle with most of the parsley and black pepper, check salt (I don't need more). Toss again until the sauce consistency is to your taste. Add a tiny splash of pasta water if it gets too gluggy.

Drain pasta and add to the skillet, tossing to combine with the sauce — 2 minutes

Serve immediately, garnished with remaining parsley and parmesan if desired.

Stir in fresh basil and adjust seasoning if necessary — 1 minute

Serve hot, topped with grated Parmesan cheese — 1 minute
