Cooking instructions

Instructions for 2 [for 3] [for 4] portion recipe.

1

Preheat the oven to 220°C/ 200°C (fan)/ gas 7

Cut your potatoes (skins on) into fries

Add the fries to a baking paper-lined baking tray (or two!) with a drizzle of vegetable oil and a pinch of pepper and give everything a good mix up

Put the tray[s] in the oven for an initial 25 min or until crisp and golden

Step 1
2

Meanwhile, peel and finely slice your red onion[s]

Heat a large, wide-based pan (preferably non-stick with a matching lid) with a drizzle of olive oil over a high heat

Once hot, add the sliced onion with 1 tsp [1 1/2 tsp] [2 tsp] sugar, half your balsamic vinegar (you'll use the rest later!) and a large splash of water

Cook the onions for 8-10 min or until they have softened and caramelised

Step 2
3

While the onions are cooking, slice your cheddar

Combine your mayo with most of your roasted garlic paste (save a little for a garnish!) in a small bowl with a splash of water and a small pinch of salt and pepper – this is your garlic mayo

Step 3
4

Wash your salad, then pat dry with kitchen paper

Reserve a handful of salad for later

Transfer the remaining salad to a bowl with the remaining balsamic vinegar and a little drizzle of olive oil – this is your balsamic rocket salad

Step 4
5

Once caramelised, transfer the onion to a plate and reserve the pan – this is your caramelised onion

Wipe the reserved pan clean, then return it to a high heat

Once hot, add the wagyu burger patty[ies], press down firmly with a spatula and cook for 5-6 min or until lightly charred

Tip: Cooking for 5? Use 2 pans!

Step 5
6

Once lightly charred, flip the patty[ies] and reduce the heat to medium-high and cook for a further 3-4 min or until browned on both sides

Once browned, top with the sliced cheese, cover with a lid and cook for a final 2 min or until the cheese has melted and the burger[s] is cooked through (no pink meat!) – this is your cheesy wagyu patty

Transfer the cheesy wagyu patty to a plate and set aside to rest for 2-3 min

Step 6
7

While the patties are resting, slice your brioche bun[s] in half (if required!)

Once the fries have had an initial 25 min, add the brioche halves to the baking tray[s], cut side up, on top of the fries and return to the oven for 2-3 min or until warmed through

Step 7
8

To build your burger, top each warmed brioche base with the reserved salad, a cheesy wagyu patty, the caramelised onion and a warmed brioche lid – this is your wagyu cheeseburger with caramelised onion

Drizzle the remaining roasted garlic paste over the garlic mayo and serve it to the side with the fries and balsamic rocket salad

Enjoy!
