Sunday Roast Beef Burger With Horseradish & Gravy

Preheat the oven to 220°C/ 200°C (fan)/ gas 7 and boil a full kettle

Peel your potatoes and chop them into quarters, then add to a pot with plenty of boiled water and bring to the boil over a high heat

Once boiling, reduce the heat to medium and cook for 10-12 min, then drain (save the pot!) and shake them around the colander to fluff up the edges

Top, tail and peel your carrots, then chop them into thick batons

Finely dice half brown onion[s], then slice the remaining onion

Add the diced onion, beef mince and half of your dried sage (you'll use the rest later!) to a large bowl with a pinch of salt and pepper

Mix thoroughly until fully combined, then shape into patty[ies] for per person and refrigerate until later

Crush your garlic cloves by squashing them with the side of a knife (keep the skins on!)

Add the drained potatoes to a baking tray with a drizzle of vegetable oil, the crushed garlic, remaining dried sage and a pinch of salt and pepper

Put the tray in the oven for 35-40 minutes or until golden and crispy – these are your herby roasties

While the potatoes are cooking, heat a large, wide-based pan (preferably non-stick) with a drizzle of vegetable oil over a medium heat

Once hot, add the sliced onions with a pinch of salt and cook for 5-6 min or until softened

Once the potatoes have had 10 min, add the carrot batons to one side of a separate baking tray with a drizzle of olive oil and put in oven for an initial 10 min

Meanwhile, dissolve your beef stock mix in 250ml [350ml] [450ml] boiled water and stir in your Henderson's Relish

Once the onions have softened, add 2 tsp [3 tsp] [4 tsp] flour to the pan and cook for 30 secs

Add the beef stock, bring to the boil over a high heat and cook for 4-5 min or until thickened – this is your onion gravy

While everything's cooking, combine your horseradish cream and mayo in a small bowl

Reboil half a kettle

Once the carrots have had an initial 10 min, add the beef patties to the other side of the tray and return the tray to the oven for a further 15 min or until the carrots are tender and the patties are cooked through

Once everything's nearly ready, put your ciabattas in the oven for 4-5 min or until they're warm and crusty, then carefully slice in half

Add your blanched peas to the reserved pot, cover them with boiling water, bring to the boil over a high heat and cook for 1 min or until they're warmed through

Tip: If the gravy has cooled down, warm it through over a low heat
