Sauté the Base:
Heat a splash of oil in a large saucepan over medium heat. Add the chopped onion and cook for 4–5 minutes until soft and translucent. Add the garlic and sauté for another minute until fragrant.
Brown the Beef:
Add the lean beef mince to the pan. Break it apart with a wooden spoon and cook for 5–7 minutes until browned all over.
Add the Sauce Ingredients:
Pour in the chopped tomatoes, ketchup, sweet chilli sauce, and the vegetable stock. Stir to combine.
Add salt, pepper, chilli flakes, all-purpose seasoning, Italian herbs, thyme, and mixed herbs. Stir everything through, bring to a gentle boil, then lower the heat and simmer uncovered for 20–25 minutes, stirring occasionally.
Cook the Spaghetti:
While the sauce simmers, cook the spaghetti in a large pot of salted boiling water according to package instructions. Drain well.
Serve & Enjoy!
Taste the Bolognese and adjust seasoning if needed. Serve the sauce over the cooked spaghetti and garnish with fresh herbs or low-fat cheese if desired.
