A few quick notes
1. Brown the onion
Cook the sliced onion in butter until tender and lightly browned before adding tomatoes and tomato paste.
2. Stir while simmering
Stir the covered soup occasionally so the potato chunks do not stick to the bottom while softening.
3. Thicken after potatoes soften
Add the flour slurry only once the potatoes are soft, then stir through to thicken the soup.

Take the browned flour mixture off the heat before transferring it to a bowl and mixing with water.
A few questions you might have
When does the sausage go in?
Add the strips after the soup comes to a boil, then reduce the heat and simmer covered.
How do I stop potatoes sticking?
Stir the soup occasionally during the covered simmer so the potatoes do not remain against the pot bottom.
How is the soup thickened?
Brown flour in butter separately, mix with water and stir the slurry in after the potatoes soften.
Should I brown the onion first?
Yes. Cook it in butter until tender and lightly browned before adding the tomatoes and paste.
When is the soup ready for seasoning?
After the potatoes are soft and the flour slurry has thickened the soup, add salt and pepper to taste.
Any more cooking tips?
Stir-fry the vegetables for 1 to 2 minutes until aromatic, then add beef broth. It brings the soup a natural sweetness from the vegetables after simmering. Cook the soup with beef broth instead of water for the best taste. For a rich taste, thicken the soup with stir-fried all-purpose flour slurry.
