Cooking instructions
Instructions for 2 [for 3] [for 4] portion recipe.
Preheat the oven to 220°C/ 200°C (fan)/ gas 7
Peel and finely slice your brown onion[s]
Heat a pot over a low heat with a drizzle of vegetable oil and once hot, add the sliced onion, your dried thyme, a pinch of salt and 1 tsp [1 1/2 tsp] [2 tsp] sugar
Cook for 20-25 min, stirring frequently, or until the onion has softened and caramelised – this is your caramelised onion

While the onion is caramelising, slice your potatoes (skins on) into thin discs, then slice each potato disc into matchsticks
Add the potato matchsticks to a baking tray (or two!) with a drizzle of vegetable oil and a pinch of salt and pepper
Give everything a good mix up and put the tray[s] in the oven for 20-25 min or until golden and crisp – these are your matchstick fries

Boil a kettle
Line a separate baking tray (or two!) with tin foil
Add your meat-free patty[ies] to the tray[s] and put the tray[s] in the oven for 10-12 min or until cooked through

Meanwhile, combine your Dijon mustard (not a fan of mustard? Just add a little!) and mayo in a bowl – this is your Dijon mustard mayo
Slice your brioche bun[s] in half

Once caramelised, transfer half the caramelised onion to a bowl and set aside (you'll use this later!)
Return the remaining caramelised onion in the pot to the heat with 2 tsp [3 tsp] [4 tsp] flour and cook for 1 min
Add your vegetable stock mix and 250ml [325ml] [425ml] boiled water and cook for 4-5 min or until the sauce thickens to a gravy-like consistency – this is your onion gravy

Once cooked, remove the meat-free burger patty[ies] from the oven, push to one side of the baking tray[s] and top with the reserved caramelised onion and your cheese flavour slice[s]
Add your brioche halves to the other side of the baking tray[s], then return to the oven for 4-5 min or until the cheeze has melted and the brioche are warmed through – this is your cheezy plant-based patty & toasted brioche
Tip: Cooking for 3 or more? Use 2 trays!

Wash your salad, then pat dry with kitchen paper
To build your burger, spread the Dijon mustard mayo over the toasted brioche base, then top with a handful of salad, a cheezy plant-based patty, a drizzle of onion gravy and a toasted brioche lid – this your French-style plant-based burger with onion gravy & Dijon mayo

Serve the French-style plant-based burger with onion gravy & Dijon mayo with the remaining onion gravy, matchstick fries and remaining salad to the side
Drizzle your white wine vinegar and a little olive oil over the salad
Enjoy!
