Preheat oven to 180°C/350°F (160°C fan).
Season lamb - Spread lamb out onto a tray. Pat dry with paper towels then sprinkle with salt.
Brown lamb - Heat the oil in a large, heavy-based, oven-proof pot over high heat (mine is 24cm / 9.5"). Add 1/3 lamb and brown aggressively all over (about 3 minutes). Remove into tray, then repeat with remaining lamb.
Brown onions - Turn the heat down to medium high and add the onions. Cook for 2 minutes stirring regularly until brown all over. Remove into a bowl.
Sauté carrots & garlic - Add the carrot and cook for 2 minutes stirring regularly until it starts to soften. Add garlic and cook for 20 seconds.
Tomato paste and lamb - Add tomato paste and cook for 1 minute stirring constantly. Add the lamb back in the pot including any juices that are on the tray. Stir to combine.
Flour - Stir in the flour and cook for 1 minute.
Add wine and stock - Pour the wine, stir until the lamb is coated in a pale red, loose paste then add the stock and stir gently until combined.
Seasoning - Add salt, pepper, thyme and bay leaves and stir well.
Oven 1 hour - Bring to a simmer, then cover and transfer to oven for 1 hour. (See note 6 for other cook methods)
Potato, turnip & onions - Remove from the oven, stir in potato, turnip and onions. Submerge ingredients as best as you can, if some of the vegetables or meat are still peeking above the sauce, that's perfectly fine.
Oven 1 1/2 hours - Cover with lid and return to the oven for 1 1/2 hours, or until the lamb is “fall-apart tender”.
Peas - Add the frozen peas, stir VERY gently using a rubber spatula, cover and leave it for 2 minutes.
Adjust salt - Remove from oven, taste sauce and add salt if needed. (Note 6)
Leave overnight (optional) - If time permits, leave the stew overnight before serving. Like all good stews, the flavours only get better the next day. Reheat it gently over a low heat before serving.
Serve - Serve hot with some warm crusty bread to soak up all that beautiful sauce! Enjoy! 😊
