- The name ‘ratatouille’ comes from the Occitan word ‘ratatolha’, meaning ‘to toss’ or ‘stir up’.

Ingredient insights for perfect roasting results
- Zucchini: First-person, I love how zucchini becomes tender and slightly sweet when roasted. If you dislike the skin, peel it, but I prefer the rustic look and texture.
- Eggplant: I find eggplant soaks up flavors beautifully, becoming silky and smoky. For less bitterness, salt slices beforehand and rinse.
- Bell Peppers: They turn soft and intensely sweet, with a smoky aroma. Use red or yellow for vibrant color, or green for a grassy note.
- Tomatoes: Juicy and oozy when roasted, adding natural acidity. Cherry tomatoes roast faster, so add them later if using.
- Garlic: Fragrant and mellow after roasting, but can burn easily. Mince finely and add midway through to avoid bitterness.
