Instructions
Prep
Thinly slice 2 medium brown onions. Crack 6 eggs into a bowl with 1 tsp salt and 0.5 tsp pepper, beat with a fork 30 seconds until just combined. Chop 2 tbsp flat-leaf parsley and snip 2 tsp chives. Whisk 2 tsp walnut oil, 0.5 tsp sherry vinegar, and 0.5 tsp salt flakes for salad.
Sweat
Melt 30g butter with 2 tsp olive oil in a 28cm non-stick pan over medium-low heat. Add onions, 0.5 tsp sugar, and a pinch of salt; cook 20–22 minutes, stirring occasionally, until deep mahogany and jammy.
Finish
Add 2 tsp red wine vinegar to onions, cook 30 seconds until absorbed. Transfer to a plate. Wipe pan clean, melt remaining 30g butter over medium-high heat until foaming.
Build
Pour 3 eggs into foaming butter, let set 5 seconds, then pull cooked edges toward centre while tilting pan for 30 seconds until surface is just set but glossy. Spoon half the caramelised onions and half the parsley over one half. Repeat with remaining 3 eggs and onions in the same pan to make a second omelette.
Wrap
Off heat, tilt each pan away from you, fold far edge over middle, then roll near edge over. While omelettes rest, butter sourdough and toast in a dry pan 1–2 minutes per side until deep golden.
Plate
Toss frisée with walnut oil dressing. Slide each omelette seam-side down onto warm plates, scatter chives and remaining parsley over both, serve with toast and dressed salad alongside.
