Detailed method
Total progress: 0 % done
Phase 1: Preparation – 20 min
Equipment: Chopping board, knife
1. Cut the aubergine and courgette into 2 cm cubes. Deseed the peppers and cut into 2 cm pieces. Slice the onions. Crush the garlic. Chop the tomatoes.
VKB: All vegetables are cut into even pieces. This ensures even cooking.
Before you continue:
Do not peel the aubergine or courgette. The skin holds the vegetable together and adds flavour.
Phase 2: Cooking the aubergine – 15 min
Equipment: Large frying pan
2. Heat 3 tablespoons of olive oil in a large frying pan. Add the aubergine cubes and fry until golden and soft, about 10 minutes. Remove and set aside on kitchen paper.
VKB: Aubergine is golden brown and soft. It has absorbed the oil.
Before you continue:
Do not overcrowd the pan. The aubergine should fry, not steam. Cook in batches if needed.
Phase 3: Cooking the courgette and peppers – 15 min
Equipment: Frying pan
3. Add 2 tablespoons of olive oil to the pan. Fry the courgette until golden and slightly soft, about 5 minutes. Remove and set aside. Fry the peppers for 5 minutes until softened. Remove and set aside.
VKB: Courgette is golden and firm. Peppers are soft and sweet.
Before you continue:
Do not overcook the courgette. It should be golden but still hold its shape.
Phase 4: Making the sauce – 15 min
Equipment: Large pot, wooden spoon
4. Heat the remaining tablespoon of olive oil in a large pot. Add the onions and cook for 5 minutes until softened. Add the garlic and cook for 1 minute. Add the tomatoes, tomato purée, thyme, and bay leaves. Simmer for 10 minutes until the sauce thickens.
VKB: The sauce is thick and fragrant. The tomatoes have broken down.
Before you continue:
Do not let the garlic burn. It becomes bitter. Cook it gently.
Phase 5: Combining – 10 min
Equipment: Large pot
5. Add the cooked aubergine, courgette, and peppers to the tomato sauce. Stir gently to combine. Simmer for 10 minutes to allow the flavours to meld. Taste and adjust the seasoning.
VKB: The vegetables are coated in the sauce. Each vegetable is still distinct.
Before you continue:
Stir gently. You do not want to break up the vegetables. A ratatouille should have texture.
Phase 6: Finishing – 5 min
Equipment: Serving bowl
6. Remove from the heat. Stir in the fresh basil leaves. Serve hot, warm, or cold. Ratatouille tastes even better the next day.
VKB: The basil is wilted. The ratatouille is fragrant and rich.
Required equipment

WAGUU Pro level
- Pro standard: Verified recipe with precise ratios and visual control points.
- Tip 1: Salt the aubergine 30 minutes before cooking. It draws out moisture and prevents it from absorbing too much oil.
- Tip 2: Cook each vegetable separately. This is the difference between a ratatouille and a vegetable mush.
- Tip 3: Add the basil at the very end. Heat destroys its aroma.
- Tip 4: Ratatouille tastes even better the next day. Make it ahead and reheat gently.

FAQ
Can I make this ahead of time?
Yes. It tastes even better the next day. Store in the fridge and reheat gently on the hob.
Can I use tinned tomatoes?
Yes, but fresh tomatoes give a brighter flavour. Use good-quality tinned tomatoes if fresh are not available.
Why is my ratatouille watery?
The vegetables may not have been cooked long enough, or the tomatoes were too watery. Simmer uncovered for a few more minutes.
Can I freeze ratatouille?
Yes. Freeze in portions for up to 3 months. Thaw overnight in the fridge and reheat gently.
WAGUU Petr advises: Cooking for 6 or more?
6–8 people: Double the recipe but use a larger pot. 10+ people: Make two batches. Ratatouille is even better the next day.

Most common mistakes
- Cooking all vegetables together – Each vegetable has a different cooking time. Cook them separately.
- Not salting the aubergine – Salting draws out moisture and prevents it from absorbing too much oil.
- Overcrowding the pan – The vegetables should fry, not steam. Cook in batches.
- Adding basil too early – Heat destroys its aroma. Add it at the very end.
