Start the Potatoes

Preheat your oven to 220°C/200°C fan/gas mark 7.

Halve the salad potatoes widthways, then pop onto a baking tray. Drizzle with oil, season with salt and pepper, then toss to coat. Spread out in a single layer, cut-side down.

When the oven is hot, roast the potatoes on the top shelf, 20 mins - you'll roast them for longer once you've crushed them.

Prep Time

Meanwhile, trim and halve the green beans.

Pick the tarragon leaves from their stalks and roughly chop (discard the stalks).

Boil a full kettle, then pour the boiled water for the sauce (see pantry for amount) into a measuring jug with the vegetable stock paste - this is your veg stock.

Get Smashing

When the potatoes have cooked for 20 mins, remove them from the oven. Use the bottom of a bowl or pan to lightly crush each potato half.

Drizzle the smashed potatoes with more oil and return to the top shelf until crispy and golden, 10-15 mins.

Meanwhile, pop a large saucepan of water on to boil with 1/2 tsp salt.

Fish to Fry

While the smashed potatoes roast, heat a drizzle of oil in a frying pan on medium-high heat. Season the fish with salt and pepper.

Once hot, carefully place your sea bass into the pan, skin-side down. Cook for 3-4 mins before turning over and cooking for 2-3 mins on the other side. TIP: To get crispy skin on the fish, don't move it around when it's cooking skin-side down.

Once cooked, transfer to a plate and cover with foil to keep warm. IMPORTANT: Wash your hands and equipment after handling raw fish. It's cooked when opaque in the middle. 

Make your Tarragon Sauce

Meanwhile, add the green beans to the pan of boiling water and cook until just tender, 4-6 mins.

Once cooked, drain in a colander, then return to the saucepan. Season with salt and pepper. Toss in olive oil if you'd like. 

While the beans cook, pop the (now empty) frying pan on medium-high heat and pour in the veg stock. Boil until reduced by a third, 2-3 mins, then remove from the heat.

Stir in the soured cream and tarragon, then heat through until piping hot. Season to taste with salt and pepper if needed.


When everything's ready, plate up the sea bass with the smashed potatoes and green beans alongside.

Spoon over the tarragon sauce to finish.
