How to make roast beef with baby Yorkies meal

Follow Jamie's step-by-step guide to make this full meal with dessert in just 30 minutes.

To start: Get all your ingredients and equipment ready. Fill and boil the kettle. Turn the oven on to 220ºC/425ºF/gas 7, and place a 12 hole shallow bun tin on the top shelf. Put 1 large saucepan and 2 large frying pans on a medium heat. Put the fine slicer disc attachment into the food processor.

Potatoes:Wash the potatoes, leaving the skins on. Chop into 2cm chunks and throw into one of the large frying pans. Cover with boiling water, season with salt and cover with a lid. Turn the heat right up, and boil for 8minutes, or until just cooked. Fill and reboil the kettle.

Beef: Quickly pick and finely chop the rosemary, sage and thyme leaves. Turn the heat under the empty frying pan up to full whack. Mix the herbs together and spread them around the chopping board with a good pinch of salt & pepper. Cut the fillet in half lengthways, then roll each piece back and forth so they are completely coated in herbs. Add the meat to the hot empty frying pan with a few good lugs of olive oil. You must turn it every minute while you get on with other jobs. Don't forget to seal the ends.

Carrots: Tip the carrots into the saucepan and just cover with boiling water. Add 2 sprigs of thyme, a couple of bay leaves, a good pinch of salt, a splash of olive oil and 1 heaped tablespoon of sugar. Cook with a lid on until tender.

Yorkies: Put the flour, milk and egg into the liquidizer with a pinch of salt. Blitz, then quickly and confidently remove the bun tin from the oven and close the door. In one quick movement, back and forth, drizzle a little olive oil in each compartment, then do the same with the batter until each one is half full (any remaining batter can be used for pancakes another day). Place in the top of the oven, close the door and do not open for 14 minutes, until golden and risen.

Potatoes: Check that the potatoes are cooked through, then drain and return to the same frying pan. Leave on a high heat and drizzle over some olive oil. Add a pinch of salt & pepper, speed-peel in strips of lemon zest and add 4 sprigs of thyme or rosemary. Halve the bulb of garlic widthways, squash each half with the back of a knife and add to the pan. Toss everything together, then roughly squash down with a masher. Toss every 3 minutes or so, until golden and crisp.

Gravy: Reduce the heat under the beef a little. Peel the red onion half. Finely slice in the food processor. Add half the onion to the beef pan with a splash of olive oil, the other half to a salad bowl. Rinse the mushrooms in a colander and slice in the processor, then add to the beef pan. Stir everything around and remember to keep turning the beef regularly for 5 minutes.

Watercress salad: Add 2 tablespoons of red wine vinegar, 1 tablespoon of caster sugar and a good pinch of salt & pepper to the onion bowl. Scrunch with one hand. Add 4 tablespoons of extra virgin olive oil. Empty the watercress on top and take to the table, but don't mix until serving.

Gravy: Remove the beef to a plate. Drizzle with a little olive oil, then cover with foil. Stir 1 heaped tablespoon of flour into the pan. Add a small glass of red wine and turn the heat up. Boil down to nearly nothing, then stir in 300ml of chicken stock and simmer until thick and shiny.

To serve: Drain the carrots, return to the pan, toss with butter and take to the table. Turn the potatoes out on to a platter. Smear 2 spoonfuls of horseradish sauce and 1 teaspoon of English mustard on to another platter. Quickly slice the beef 1cm thick, using long carving motions. Sprinkle over a pinch of salt & pepper from a height, then pile the beef on top of the horseradish sauce and mustard. Add any resting juices to the gravy and serve in a jug. Toss and dress the salad quickly, then get the Yorkies out of the oven, and take them to the table and tuck in with a glass of wine.
